In the whole process of home decoration indoor pollution control

Previous: air quality precontrol mainly

For most families, the mainest material of indoor pollution is ---- formaldehyde. Formaldehyde is the important part of adhesive, so everything that relates to adhesive,plastic bag manufacturer including man-made board, paint, carpet, furniture will contain formaldehyde exceed the standard, if the individual will necessarily cause the air quality standards. It is also noteworthy, even if each of the products are in the range, if the room in the building materials containing formaldehyde add up too much, it is easy to cause the air quality standard, so owners in the decoration project of time, should be grasped, try not to get too complicated.

Current state of the harmful substances have the strict limit, building materials" ten standard limit of harmful substances" constraint, and the decoration," 2005 Jiezhuang contract" have qualified as part of the evaluation of indoor air quality is qualified as part of the renovation, to ensure that the owners of the health benefits.

Late: environmental control products with caution

" China indoor environment pollution control systems engineering " of the indoor environment pollution investigation data shows, China indoor environment pollution problem is very prominent," 2004 November, national indoor environmental pollution control office" office furniture was established in Beijing. It is guiding the national indoor environmental pollution control of the professional bodies, management of indoor environmental pollution, indoor air purification and to guide and standardize the management of products.

According to the Chinese interior decoration Association indoor environment monitoring center director Song Guangsheng, currently on the market of environmental governance products reach the hundreds, and most of them are speculation, true to its commitment to action very little.pearl jewelry As a result of these control products of pharmacologically different, there is no relevant standards, consumers in the purchase when you can view the inspection report, test report for most no products, consumers in the purchase will be especially careful, it is best not to buy.

The screen of the external wearing underwear

External wearing underwear, show the female body beauty, has become a kind of fashion. But in more than half a century ago, social customs, yet then opened, some western female star has solved the coat, on the screen to show their inner beauty. This was, and even later clothing habits and fashion trends,printing company have played a certain effect.

The choice to use Flash animation

Many use slow computer visitors find animated icons easily run out of system resources, make the site operation becomes very difficult, therefore,Web Content Management System should give the user a skip animation using Flash selection.

As little as possible using the Flash plug-in

Although many Web designers think Flash function is very powerful, and Netscape5.0 will support Flash, when in use, does not need to download any plug-ins. However, better cancel it use Flash interface ideas.

Allows users to preview the image

If have placed large images on the web, it is best to use the Thumbnails software, the image is scaled down versions of the preview is displayed, so the user does not have to waste time and money to download and they don't want to see the big picture.

Animation and contents should combine

Ensure that the animation and content related.Website Development They should all blend into one harmonious whole. And webpage, not dry. The animation is not just Macromedia Director making things simple accumulation.

Using sound

Voice utilization should also be vigilant. Inline sound is another tribute webpage designer. Because of the excessive use of voice will make the downloading speed is very slow, and did not bring much benefit to visitors. The first voice heard a mouse may be very interesting,L-Carnitine but many times later certainly will be very annoying. The use of sound, should be carefully considered sound will bring you what.

With Java and AxtiveX

The webpage should minimize the use of Java and AxtiveX. Because not every browser will use it, only those Netscape and earlier versions of Explorer users only need it. Another Mac in the treatment of Java has problems, excessive use of Java, makes the Mac collapse.

Divided into high-pressure ( by high pressure process from ethylene synthesis, Gaosuibuyou Thailand poly bags the synthesis pressure is 100 ~ 300MPa, the temperature of 150 ~ 275, 0.05% ~ 0.1% oxygen or peroxidase as catalyst; synthesis or in the mixing tank for intermittent occurrence, or in a tubular reactor in continuous ), low pressure, middle pressure method three.

High pressure method used in the production of low density polyethylene, this method development early, the polyethylene production has accounted for about 2 of total production of polyethylene / 3, but with the production technology and development of catalysts, its growth rate has significantly lagged behind the low voltage method. Low pressure method. Its implementation method, a slurry method, solution method and gas chromatography.

Slurry method is mainly used for the production of high density polyethylene, and the solution method and gas phase method not only can produce high density polyethylene, but also through the addition of comonomer, production, low density polyethylene polyethylene ethylene, also known as linear low density polyethylene. In recent years, a variety of low-voltage technology develops very fast. MV only Philip is still in use, the main production is high density polyethylene.

Polyethylene characteristics

Polyethylene odorless, non-toxic, feel like wax, has excellent low temperature properties ( lowest service temperature up to - 70 to - 100 degrees C), good chemical stability, resistance to most acid-base corrosion ( intolerance with oxidation properties of acid ), room temperature, soluble in common solvents, water absorption of small, but because of the linear molecule can be slowly soluble in some organic solvents, and no swelling, electric insulation performance; but the polyethylene for environmental stress ( chemical and mechanical action ) is very sensitive, heat aging resistance difference.

Polyethylene properties varied with varieties, mainly depends on the molecular structure and density.

( 1) LDPE: low density polyethylene, high density polyethylene

( 2) LLDPE: linear low density polyethylene

( 3) MDPE: medium density polyethylene resin, Shuangfeng

( 4) HDPE: high density polyethylene, low pressure polyethylene

( 5) UHMWPE: ultra high molecular weight polyethylene

( 6): CPE modified polyethylene,plastic bags supplier cross-linked polyethylene ( PEX )

( 7): ethylene copolymer of ethylene propylene copolymer ( plastic ), EVA, copolymer, ethylene - other olefin ( such as POE, octene copolymer of cyclic olefin ), ethylene unsaturated ester copolymer ( EAA, EMAA, EEA, EMA, EMMA, EMAH )

The molecular weight of 3000000-6000000 linear polyethylene called ultra high molecular weight polyethylene ( UHMWPE ). Ultra high molecular weight polyethylene intensity is very high, can be used to make the body armor.

Main methods: Polyethylene liquid chromatography (also divided into solution and slurry method ) and gas phase method ( material in the reactor of phase type ). Our country mainly used Ziegler catalyst slurry method.

Conditions and process description: more than 99% purity ethylene in catalyst of titanium tetrachloride and two ethyl aluminum chloride in the presence of pressure and temperature, in 0.1-0.5MPa 65-75 C HDPE slurry polymerization in gasoline. The alcoholysis destroys residual catalyst,solar module cell neutralization, washing, and recovery of gasoline and unpolymerized vinyl, after drying, granulation product.
