Advancements in the Demolition Industry

Posted by Writer at 4:39 AM 0

The demolition industry has been around since the dawn of the mechanical age of manufacturing. The moment that modern architecture came about to address the growing need to maximize allocated land and resources, demolition engineering was right behind it, waiting for a signal to enter.

Demolition is the process of imploding a structure to clear a space for another structure to rise. Often, old buildings and structures are imploded to give way to new concessionaries or investors. In the city space, urbanity and modernity both require demolition to maximize use of land and to make sure that social utility of structures are also maximized.

Solid wastes during demolition

According to Sung Kin Pun in an engineering journal from the University of Sidney:

“Conventional mechanical building demolition produces numerous solid wastes, most of which are sent to landfill directly that severely degrade the living environment. Just-in-time building demolition has been developed recently with a management strategy to facilitate waste reuse. Procurement management plays a significant role in just-in-time building demolition. In particular, the demolition tendering selection needs to consider contractors' environmental performance in addition to project costs.”

Chunlu Liu, a co-author of the journal article A Framework for Material Management in the Building Demolition Industry clarifies the process of production and its reverse relationship to demolition engineering:

“Since building demolition is the reverse process of building construction, the issues involved in a demolition project are fundamentally identical or similar to those in a construction project. Yet they are different in context and implementation strategies, particularly the project contracting and waste material supply chain management (Liu et al., 2004). Although construction procurement concerns the purchase of building materials while the waste material chain is to market the waste materials, the management strategies and models in the building construction process can be adopted into the procurement management of building demolition projects.”

New technologies in the demolition industry

Because of the depletion of natural resources in all parts of the globe, there is a need to increase the effectiveness of technologies employed during demolition. Waste management is just one faltering matter to deal with. The sum energy expended during demolition is another. Juridical steps are also necessary, as expounded by Liu:

“In particular, increasing landfill tipping fees and compulsory high recycling rates on demolition wastes impose strong legal incentives for the construction industry to allot attention on environmental issues (Ling et al., 2002; Merman et al., 2004). A growing interest in deconstruction and material reuse is forming within the industry (CSC, 1994).”

The labour intensive nature of demolition

Demolition is labour intensive for the simple reason that it required selective handling of materials. The value of the waste produce after demolition should also be high, because demolition industries aim for high recyclability and reusability, in keeping with the global agenda of sustainability.

To address the problem of management during demolition, Liu expounds on a particular approach to improve facilitation during demolition projects:

“Keeping in mind that waste reuse is one of the most significant objectives of a building demolition project, Just-In-Time (JIT) demolition was developed as a management strategy to facilitate reuse of building materials (Pun & Liu, 2003). JIT philosophy is a mature management approach nurtured in the manufacturing industry. The main concepts of JIT include reducing the inventory of raw materials and products, and speeding up the manufacturing process by decreasing the manufacturing batch size.”

Indian Handmade Carpet Industry Biting Dust

Posted by Writer at 4:39 AM 1 comments

The once flourishing Indian handmade carpet sector is presently reeling under tremendous pressure on account of the global economic slowdown and an unfavourable tax policy.

Dwindling demand, shrinking profit margins and lack of adequate government assistance have made it difficult for small scale industries (SSIs) in the handmade carpet sector to perform efficiently and sustain their businesses.

Rising taxes have further added to the woes of small handmade carpet manufacturing and export units, who have already been hit hard by the contraction of export orders by overseas clients.

The export-oriented handmade carpet industry has a major share in the international markets, and provides employment to millions of people in the country. More than 2 million rural artisans depend on this industry for their sustenance. Over Rs 35 billion worth handmade carpets are exported to various countries by small and mid-sized carpet manufacturing and supplying units.

However, the declining demand and withdrawal of orders placed by the international clients have led to an uncertain future for the carpet weavers and exporters. According to an All India Carpet Manufacturers’ Association (AICMA) report, export orders worth about Rs 3 billion have been cancelled recently.

Besides, delayed payments and reluctance of banks to offer credit assistance to the carpet industry has further made it difficult for them to sustain their production and export operations. Stiff competition from neighbouring countries like Pakistan, China and Nepal among others is also leading to erosion of profit margins of carpet exporters thereby rendering them less competitive. The stringent financing norms of banks for lending to this sector are the other major obstacles for small units to get easy access to loans.

To rescue the carpet industry from the ongoing crisis, the government needs to undertake important initiatives and introduce tax exemptions. Marketing and credit support from the government and banks can help garner adequate revenues for the industry.Technology upgradation, enhanced duty drawback rate (DDR) and low interest charges on export finance can help revive the fading industry.

Packaged Industrial Air Handling Units

Posted by Writer at 4:39 AM 0

NISCO Co. just completed major re-design of Industrial Make-Up Air Units for industrial plants ventilation needs.

Negative Air Pressure in industrial manufacturing facilities can create problems such as:

- Exhaust fans losing performance, as the building pressure becomes negative.

- Pilot light outages and exhaust system failure on natural draft gas equipment.

- Cold air drafts and infiltration of dirt and contamination from outside.

- Difficulty opening or closing exterior doors.

Nausea and headaches among personnel due to inadequate ventilation. In temperate climates or during mild weather, moderate amounts of make-up air can be supplied by simply opening windows or overhead doors. However, this is usually not the case in industrial and commercial facilities. Forced ventilation Make-up air is required.

Direct Gas-Fired Make-up Air Units supply tempered and filtered air to the indoor environment. In summer, a direct-fired unit may be used as an air handler, with the heater disabled. By adding a DX or evaporative cooling section to the unit, it may be used to supply conditioned air year round.

Make-Up Air Applications:

There are three general applications for Make-Up Air Units:

- Direct Compensating Ventilation

- General Area Ventilation

- Door Heating

Direct Compensating Ventilation.

Conditioned Air is Delivered to the Immediate Vicinity of Exhaust. This is the case for welding fume extractors, stovetop exhaust hoods, paint booths, or similar applications.

General Area Ventilation.
 
Conditioned Air Blankets Entire Area of Building to Compensate for Many Exhausts. Introduced in Cleanest Part of Building - Flows to Negative Pressure Areas - Picks up Dust, Vapors, and Odors en route.

Door Heaters

Heated Air is introduced at open doors to warm incoming air or compensate for loss. Heater may also be used as part of an "air door" system.

Typical Industrial Uses:

* Plating Tanks

* Paint Spray Booths

* Welding Operations

* Chemical Exhaust

* Degreasing

* Factory Ventilation

* Plastic Molding

* Foundry Works

* Grinding & Buffing Operations

Typical Commercial Uses:

* Warehouses

* Kitchens

* Entryways

* Gymnasiums

* Pools

* Exposition Buildings

* Garages

Make-Up Air Volume Requirements:

The recommended method for calculating Make-up Air Volume is to determine the total CFM capacity of exhaust fans, blowers, stacks, etc. in the building and add 10%. This will create a positive pressure in the building.

When information is not available, the following estimates may be used to determine approximate requirements:

- Paint / Spray Booth: 100 to 200 CFM per sq. ft. of face opening.

- Oven Exhaust: One air change per minute.

- Fume Exhaust: Area of Pipe (in square feet) x velocity (3,000 feet/min average) = CFM.

- Roof Ventilator: same as Fume Exhaust.

- Canopy Hoods: 100 to 300 CFM per square foot of hood open area.
 
- Furnace Combustion Air: Minimum CFM = BTU/hr rating / 6,000.

- Drying, Baking, Curing Ovens: 100 CFM per square foot of booth cross section.

- Pickling or Cleaning Tanks: 150 CFM per square foot of door opening or 200 CFM per square foot of hood face opening.

A Direct Gas-Fired Air Heating System may be used in an industrial or commercial application for any or all of the following purposes:

. Make-Up Air Heating - Air is introduced to a building to replace air being exhausted.
. Space Heating - A unit provides primary or supplementary heating to a building space.
. Space Pressure Control - Building or Room Pressurization is held within a range.

Modern Eco-Sustainable Industrial Processing

Posted by Writer at 4:39 AM 0

The industrial process produces a lot of garbage. Very often these processes are highly toxic or in any case not sustainable. It is just from the industry sector that comes most pollution.

Among community regulations, the Kyoto protocol, the warning for the global climate change, also the enterprises slowly have to conform to minimum standard. They can’t pretend nothing is happening anymore. This is the real challenge of this millennium. Sustainable economy is centered on a sustainable development model. This kind of economy, still unfortunately not enough developed, provide for society development being pursued able to respect the environment and use sources at our disposal to allow them regenerating. This way, also future generations will have the chance to use these resources. Unfortunately this concept has been understood too late from society, so now we are very backward for what concerns this field of development.

But there are also many enterprises that are moving to change this state of things.
The increasing market competition obliges operators to focus on product quality, without increasing costs and production efficiency, also and especially in the light of new European regulations. This is just why always more enterprises are focusing on innovation and research of new materials and new equipments.

A very important sector for the ecology is for example the one of industrial grinders. Industrial grinders can be used to reduce the volume of processing waste of: cumbersome plastic materials (bins, boxes, bumpers etc.), paperboards, wood, packaging, fruit shells and stones, leather and hide waste, bark, aluminum and steel cans, car tires, branches, and other. These machines are essential for the shredding and waste management, new technologies minimize the contribution of labor input for the loading and unloading of the shredder and the facilitation of all operations of waste recycling.

Other machines very important in this sense are also the waste compactors. The compactors are, to date, the best solution for anyone who wants to manage in a simple, secure and independent way the collection of waste. These machines are technologically advanced but very common to use, and make the disposal of waste and their recycling in particular, easier and faster.

But not just in this industry sector, in all sectors, companies aim to the design and creation of modern industrial machinery and new industrial processing that respect the environment or people, from mixers to pumps, to powder coating instead of spraying coating machines, to sustainable products pointing to a modern economic sustainable development plan. In the last years, so, we watched the birth of several innovations in this field, the creation of new machines and new technologies.

From innovative technologies for waste management to the creation of new machinery to respect the environment and of new processes that don’t harm environment or people, this is this is certainly the way forward in the future. Also, and especially at a time of severe economic crisis, to get out quickly from this moment of impasse, it is essential to continue to invest in research and development. Because it is precisely on this front that we can and must compete on the world market, not get so outdated on productions, but by innovating and offering products and services always at the forefront.

If you primarily sell your goods or services to other companies and businesses, then you are always looking for a new way to network. Now it is easier than ever to get word out to a specific set of companies with industry lists. You are able to target a specific industry with these lists, and send them promotional information in a way that is cost effective and efficient. Learn more about purchasing these incredible marketing tools in the information below.

Choose to Target Specific Industries

You may find yourself in a bind when it comes to industry lists. The idea is to find a company that will allow you to purchase lists that are tailored to your needs. You may not need a variety of industries, and instead may want to focus your marketing efforts on only one or two specific ones. If this is the case, then a high quality list broker will make it possible with custom lists.

Don’t Pay More When You Can Spend Less

There is no need to fork up thousands of dollars for industry lists. In this tightening economy, we could all stand to hold on to a little more of our money. There are list brokers available who can offer you these same lists for under $200, and can save you quite a lot of money.

These are essentially the same lists, but the cheaper ones will have a greater number of leads that fail. The majority of the leads you receive will be accurate, but some will not be. If you are smart and use a free method to reach your prospective lead such as fax, then it will not cost you a cent to try each lead. In the long run, cheaper industry lists are a greater value and require no extra effort on your part.

Industrial Machines for the 21st Century

Posted by Writer at 4:39 AM 0

The 21st Century inherits much of the conveniences of industrial work from the discoveries and inventions made a century before. Computing and telecommunications technologies have seen some of its most furious pace of growth and development in the last 50 years. Miniaturization in electronics and data storage made these computers and telecoms gadgets not only small enough to be hand-held, but more powerful and affordable to the common man.

Aerospace and military sciences and engineering contributed much of the impetus to spearheading developments in these areas. And as a result, they have made inroads in the commercial industries that make life at home and work in the office a lot more productive and convenient.

Mainframes and Super Computers

Airlines and the aerospace industry have long been home to mainframe computers. These are highly robust computers that can do multiple tasks without suffering the problems found in our home and desktop PCs.

The requirements of the business often demand continuous availability of computing and networking resources. Only industrial-grade computers can fill this need. The last years of the 20th century saw the emergence of mini-computers that can work cost-effectively as departmental computers because of their specific highly focused computing resource, such as for accounting or purchasing functions.

They can be networked to enable seamless data access across the levels of the organization. But while they have achieved industrial-strength features, mainframes and super-computers have not lagged behind and they remain the staple computing resources in large industries and business complexes.

The global markets now confronting businesses have made mainframes the ideal core brain in large corporations. Super thinking computers that organize and process billions of data points are processed in parallel computers that can make up what are called super computers. The special effects in movies have moves the audience to expect nothing less than realistic visuals and sounds and the computers that process these images require so much computing power, like having a CPU for each screen pixel, that only massively parallel computers can do the job.

Robotics

This is a highly specialized computer application that is basically an output peripheral of powerful computers. Rather than having a printer as an output device, robotics employ mobile and agile armatures as output devices that can manipulate objects to achieve an end product or object. Automobile plants have these robots that can grab panel molds from forges, paint them and assemble with consistent precision humans would have difficulty achieving. And all these are controlled remotely from computers in an office.

Similarly, large warehouses with automated systems have robots installed along rails parallel to warehouse shelves and bins and controlled remotely from computers. These robots can sense the storage numbers and retrieve or pick up the needed parts or materials for distribution without the need for human intervention.

Hazardous conditions at work can easily and cost-effectively be performed by robots. Bomb squads and military units have them to handle life-threatening situations. Unmanned military spy planes are essentially robots that fly enabling remote sensing of enemy targets. The 1986 Chernobyl nuclear plan accidents made clear that robots can do the job of cleaning up radioactive and chemical accidents that would have the potential to kill any person doing it.

For the 21st Century industry, we can expect more and more robotic technologies to do the job. Mainframes and super computers can be right behind them remotely controlling these robots with increasing efficiency in more complex jobs.
