In October 2008, after we have gotten the patent license of German company named STRICKER IRD PATENT GBR, our company began to produce and sell infrared crystal drying equipment. This equipment is one of the world’s advanced technical products currently.

A. Description

1. It can complete crystallization and drying at the same time, with short time、 low energy consumption and high efficiency. The quick dehumidification can lessly chang the Molecular Structure of raw materials and maintain the physical performance of raw material.

2. Application materials: PET、PLA、PC and so on. New material or recycling materials. Best application for PET bottle flakes、board material、dehumidified drying before drawing.

3. Theory of drying: Using the special performance of short-wave to radiate the surface layer of raw material directly, then the temperature rises from the interior of raw material. Moisture is heated quickly then gasified instantly. It transfers from internal to outer then discharge.In a shorter time it can get the best crystallization drying effecy that raw material needs.

B. Compared with traditional dehumidifier

1. Low energy consumption,producing PET(400kg/h) consumes about 39 kw/h, saved 50% of traditional energy consumption(82kw/h).

2. About 10 to 20 minutes can complete crystallization and drying at the same time; Traditional dryer need about two hours crystallization and four to five hours dehumidification.

3. Water ratio of final product is 50ppm-85ppm; Water ratio of traditional dryer product is 90ppm-130ppm.

4. Power generated of infrared crystal dryer is less than traditional dryer.

5. It is easy for infrared crystal dryer to change raw materials and clean,taking only 30 minutes; Traditional dryer need 2-3 hours.

6. For infrared crystal dryer, little occupancy and simple installation; For traditional dryer, large occupancy、much auxiliary materials、heavy working load and requiring regular change for drier、heater、fiter and etc.

7. For infrared crystal dryer, applicable for all plastic products; For traditional dryer, different raw material with different designs.

According to the comparation, we can clearly know that compared with a traditional dryer, the infrared crystal dryer has the absolute advantage. I believe that in the near future, it will replace the traditional dryer and become the most popular dryer.

Plastic film is a thin gauge packaging medium used as a bag or a wrap. Examples include grocery sacks, trash bags, drycleaner bags and plastic wrap. Plastic film is less than ten mils in thickness, with an average of 0.7 - 1.5 mils. A mil is 0.001 inch. Most plastic trash bags are less than 1.0 mil in thickness.Plastic film recycling is hard because it can hardly get profits,but as the world has recognized the importance of this matter,goverments take more and actions to support the recycling business,so i believe this has a bright future.

Plastic film provides 6 percent of all packaging and 33 percent of plastic packaging. Flexible packaging includes plastic film, paper bags, aluminum foil and cellophane. More than half of flexible packaging is plastic. Paper packages are most of the rest, with aluminum foil supplying a small percentage.

Different resins and colors make plastic film difficult to recycle. More than 60 percent of plastic film uses low-density polyethylene (LDPE) or linear LDPE resin and approximately half of plastic film is pigmented. Our company also provide PE film recyling machine.

Many films also blend or coextrude two or more resins. Also, individual product characteristics may create remanufacturing problems. For instance, stretch wrap requires a “tackifier” to make the wrap cling, but this product quality is not desired in a bag.

The operators of Closed Loop Recycling’s pioneering plastic bottle recycling facility at Dagenham in East London have claimed that the site will be fully up-and-running again in “a matter of weeks” after it was hit by a fire last night (October 13).

Fire engines were called to the plant, which became the first in the world to recycle mixed plastic bottles back into food grade plastic when it opened in June 2008, at 9.24pm, just four minutes after the fire broke out.

London Fire Brigade confirmed that six fire engines and around 30 firefighters attended the fire, which was under control by 12.34am this morning, and that the cause of the blaze was now under investigation.

None of the 17 staff working in the plant at the time were injured in the incident.

In a statement, Closed Loop Recycling confirmed that a “localised” fire had broken out on the plants PET bottle recycling line, and claimed that the blaze was contained “swiftly”, adding that, with the fire put out, there was no further risk of outbreaks.

It added: “Whilst the cause of the fire is still being investigated, it is likely that it was caused by a technical fault. There is no environmental impact to the local area and inside the plant there has been some loss of stock but a full assessment of the damage is currently underway.”

Speaking to letsrecycle.com this afternoon (October 14) about the incident, a spokeswoman for Closed Loop said that it was “too early” to say exactly what stock had been affected, but she stressed that any impact on the plant’s suppliers of waste plastic bottles - such as Veolia - and its customers would be “minimal”.

She added that the company had been in touch with its suppliers as soon as it knew about the fire.

The company’s managing director, Chris Dow, praised the “initiative” of the plant’s staff in limiting the blaze to the PET line, and added that: “Our team will have the plant fully operational again by the end of today, with full operations restored within a matter of weeks.”

The spokeswoman explained that sorting and grounding bottles into flakes at the plant - the first stage of the process - was not affected, but that the “washing and food grade” for PET “will be affected for a few weeks”.

PET bottles which enter the facility are sorted and then ground into flake before being ’super-cleaned’ to produce a raw material that can be used in food applications.

The £12 million Dagenham facility has received considerable praise since it opened, being hailed by politicians from all sides of the political spectrum, while WRAP’s chief executive Liz Goodwin claimed its opening represented a “step change” in plastics recycling.

The list of customers for the HDPE and PET flake produced by the plant, which can reprocess up to 35,000 tonnes of mixed plastic bottles a year, includes big names like Coca Cola, Marks and Spencer and milk carton manufacturer Nampak.

What Are Plastic Granulators?
Plastic Granulators are the machines that are used to convert non-biodegradable plastic products into granules, so that they can be recycled and put to work once again. The plastic bottles, containers, bags and packaging materials are among the solid wastes that must be eliminated from the environment. As plastic is non-biodegradable, these waste products are broken down by granulators and sold to the plastic manufacturers and molders.

Components of Granulators
Plastic granulators consist of electric motor and rotor with cutting blades attached to it. The setup is enclosed within a chamber and a screen is accommodated to assess the process of breaking down of the plastic.

Working of Granulators
The working of Plastic Granulators is very simple. The electric motor installed in these machines rotate the rotor and the cutting blades attached to it. The waste plastic items are put in the chamber, where they are converted into small pieces. The screen helps you to watch the process of granulating and make sure that appropriate size of granules is achieved. Reprocessing might be required in case you find the plastic size to be larger than required.

It is better to obtain small pieces of plastic, which are easy to mold by the manufacturer.

Buying Plastic Granulators
A plastic granulator can be purchased for the industrial use as well as for the residential use. An important specification of these machines is kilogram per hors. This specifies the amount of plastic that can be processed by a granulator in one hour. So, you can purchase a plastic granulator by specifying your needs.

Taking Care of Plastic Granulators
It is necessary to take a good care of the plastic granulator to ensure its long-term business usage. For instance, these machines must be cleaned properly after every session of plastic processing. The blades of the granulator must be oiled periodically to maintain their efficiency. The screen must also be cleaned to maintain its visibility. Also, the machine should be kept away from inexperienced users and children; otherwise it might prove dangerous for them.

Whether you’re concerned about personal protection from germs while in public or you’re performing open heart surgery next week, a surgical mask helps protect you from outside contamination and vice versa. There are pre-fabricated surgical masks, but sometimes it’s more fun to make your own. Constructing your own surgical mask can also be a good idea if you’re making a doctor costume for Halloween  and you need a durable mask. Best of all, a mask you make yourself can be customized to fit your own face.

Instructions

Step 1

Make a pattern for your surgical masks. Get a piece of paper and cut out a rough surgical mask shape. Hold it up to your own face and look in the mirror. Is it too big or small? Does it extend too close to your eyes or down below your chin? Keep trimming away paper until you have the shape you want. This is now the pattern for your surgical masks. If you’re planning on making lots of masks, transfer the paper pattern to sturdy cardboard.

Step 2

Put your pattern over some soft, thick fabric. Draw the pattern onto the fabric as many times as necessary to make the number of masks you need. Leave a little extra to account for any mistakes you might make. After all, you can always trim the fabric a little, but you can’t put any back.

Step 3

Cut 1/2-inch strips of the fabric. Fold these in half and sew them around the edges of your masks to make the edge strong and keep them looking even. These also make the seal a little stronger to keep your breath from spreading too much.

Step 4

Attach elastic strips to the surgical masks so you can loop them around your ears, securing the surgical mask in place. You have many options. You can get small cords of elastic and run them through the top and bottom seams of the masks. You can simply sew the lengths of elastic cable to the masks at the top and bottom of the sides, making ear loops.

Step 5

Try on the first surgical mask you make to ensure you’re on the right track. Make adjustments to the length of elastic for a tighter or looser fit. This is also an opportunity to see how the mask looks in use. If the elastic pulls the mask too close to your eyes, trim the next mask a little bit to see if you get a better fit.

Plastic recycling codes come from the The Society of the Plastics Industry, Inc. (SPI) that introduced its resin identification coding system in 1988 after lobbying by recyclers. The recycling codes are explained below.

Number 1 Code - Polyethylene Terephthalate, PETE
