chemical and physical properties

chemical and physical properties: Typically, commercially available PPE or PPO materials are generally mixed with other buy full lace wig materials such as PS, PA and so on. These hybrid materials are generally still known as PPE or PPO. Hybrid PPE or PPO better than the pure material processing characteristics. Characteristics vary depending on the led perimeter displays, such as the ratio of PPO and PS. Mixed with PA 66 of mixed material at high temperatures with greater chemical stability. Moisture absorption of this material is very small, its products have excellent geometric stability. Mixed with non-crystalline material of PS, while the material is mixed with the PA crystalline nature. Glass fiber additives can reduce the shrinkage to 0.2%. This material also has excellent electrical insulation properties and low coefficient of thermal expansion. The viscosity depends on the material in the mixture ratio, PPO rate increase will result in increased viscosity.
PS polystyrene Typical Applications: Packaging household utensils, trays, etc., electrical (transparent container, light diffusers, insulation film, etc.).
injection molding process conditions: drying: Unless stored properly, usually does not require drying. If you need dry, recommended drying conditions for 80C, 2 ~ 3 hours. Melting temperature: 180 ~ 280C. Flame-retardant materials for the upper limit of 250C. Mold temperature: 40 ~ 50C. Injection pressure: 200 ~ 600bar. Injection speed: It is recommended to use a fast injection speed. Runners and gates: You can use all conventional types of gate.
chemical and physical properties: most of the commercial use of PS is transparent, non-crystalline materials. PS has a very good geometric stability, thermal stability, optical transmission properties, electrical insulating properties and a very small moisture absorption tendency. It is resistant to water, dilute mineral acids, but can be strong grp/frp storage tank acids such as concentrated sulfuric acid are corrosive and can in some organic solvents in the swelling deformation. Typical shrinkage of 0.4 ~ 0.7%.
PA12 Polyamide 12 or nylon 12 Typical applications: water table and other business equipment, cable sets, mechanical cam, slide mechanism and bearings.
injection molding process conditions: drying: before processing should ensure that humidity below 0.1%. If the material is exposed to air storage, it is recommended to air dry in the 85C heat 4 to 5 hours. If the material is stored in a closed container, then the balance after three hours the temperature can be used directly.
melting temperature: 240 ~ 300C; characteristics of materials for no more than ordinary 310C, flame-retardant properties of materials for no more than 270C.
mold temperature: for the unreinforced material is 30 ~ 40C, or for large area thin-walled components is 80 ~ 90C, for enhanced materials for the 90 ~ 100C. Increase in temperature will increase the crystallinity of the material. Precise control of mold temperature on the PA12 is very important. Injection pressure: maximum to 1000bar (recommended minimal pressure and high melting temperature). Injection speed: high speed (for a glass additive material better).
runners and gates: For non-additive materials, as materials, low viscosity, flow should be about 3mm in diameter. Materials required for the enhanced 5 ~ 8mm diameter of the crowd said. Flow channel shape should be all round. Note the entrance should be as short as possible. You can use various forms of the gate. Large plastic parts do not use a small gate, which is to avoid excessive pressure on the plastic parts or excessive shrinkage. Gate thickness equal to the best and the thickness of plastic parts. If the submarine gate, the proposed minimum diameter of 0.8mm. Hot runner mold is very effective, but requires very precise temperature control to prevent material leakage or freezing in the nozzle. If you use the hot runner, cold runner gate size should be smaller than.
chemical and physical properties: PA12 from butadiene linear, semi-crystalline - crystalline thermoplastic materials. It features and PA11 similar, but different crystal structure. PA12 is a good electrical insulator and as polyamides and other moisture will not affect the insulation performance. It has good chemical stability, impact resistance machines. PA12 has many features and enhancements in the plastics area of ​​improved varieties. And PA6 and PA66 compared to those materials have a lower melting point and density, with a very high moisture regain. PA12 on the strong non-oxidizing acid resistance. PA12 depends on the viscosity of humidity, temperature and storage time. It's good liquidity. Shrinkage of 0.5% to 2%, depending on the variety of materials, wall thickness and other process conditions.
PS polystyrene Typical Applications: Packaging household utensils, trays, etc., electrical (transparent led waterproof Switching Power Supply , light diffusers, insulation film, etc.).
injection molding process conditions: drying: Unless stored properly, usually does not require drying. If you need dry, recommended drying conditions for 80C, 2 ~ 3 hours. Melting temperature: 180 ~ 280C. Flame-retardant materials for the upper limit of 250C. Mold temperature: 40 ~ 50C. Injection pressure: 200 ~ 600bar. Injection speed: It is recommended to use a fast injection speed. Runners and gates: You can use all conventional types of gate.
chemical and physical properties: most of the commercial use of PS is transparent, non-crystalline materials. PS has a very good geometric stability, thermal stability, optical transmission properties, electrical insulating properties and a very small moisture absorption tendency. It is resistant to water, dilute mineral acids, but can be strong oxidizing acids such as concentrated sulfuric acid are corrosive and can in some organic solvents in the swelling deformation. Typical shrinkage of 0.4 ~ 0.7%.
PVC (polyvinyl chloride) Typical Applications: water natural human hair pipes, home pipes, house siding, business machine housings, electronic packaging, medical devices, food packaging.

"This is the 16th China International Kitchen & Bath Show, many exhibitors use microblogging to pass out information. Southern RoHs driver for led screen was informed, through the microblogging Sina home out of the most talked about brand named Wrigley, nine, animal husbandry, the buildings, Washington, waves whales were present, and Ke Lani, constant cleaning, Eagle bathroom, Faenza, security Chinese brands are also costumes to help out.

"kitchen cake is still the industry to accelerate growth, but LED ceiling light mode from extensive quantitative change to qualitative change in accuracy, while from a business point of view, the exhibition was to show features from functional changes in trade." Ke Lani home marketing director Zhu Chunyun told reporters the South, bid farewell to "profiteering era", the basic kitchen industry to reach a consensus: the brand is the business performance.

"round 'shuffle' is an adjustment of the ranking"

kitchen industry as China's "benchmark" and "barometer", Shanghai Kitchen Health Fair has so far held 15 sessions, exhibition scale new high this year, a new exhibition opening of the Expo Theme Pavilion, with a total exhibition area of ​​about 250,000 square meters.

"exhibition kitchen to participate in the most direct effect 'that I still exist', so that colleagues, dealers, designers and consumers to know your brand exists." SSWW sanitary assistant to the chairman, the market Yang, director of events held at the home on Sina told reporters the South, the past few years, "the kitchen industry major reshuffle" argument sound growing clamor, but the market performance, "shuffle" Which is not the well-known enterprises. " wash "," Bridge or 54, the number of resulting business or that a few, do not rise, 'shuffle', but the result is to adjust the 'brand' of rank ordering. "

It organizers, in 2009 the Shanghai International Exhibition kitchen companies have 2492, 2010, this number rapidly increased to 3224, this year will further increase the number of businesses, bathroom alone, there came from Guangdong, Zhejiang , Fujian, Shanghai, Italy, Germany and other regions more than 900 exhibitors debut.

Ke Lani home home marketing director Zhu Chunyun Sina forum admitted to reporters, "Shanghai is the business development and acceptance of brand reputation, when more and more enterprises to change the past, the idea of ​​the exhibition site to take orders, did her best 'show products, show techniques, show creativity' behind, we all compete for a leading consumer boom in the 'eye focal point'。"

kitchen and home manufacturers collectively "microblogging Marketing "

new show with beautiful models, looking for celebrity endorsements, advertising in the exhibition area hit ... ... this is plainly marketing tactics are commonly used in previous years, and this year's Festival Highlights is collective work kitchen business portal Sina microblogging, microblogging start to rally, want to build "never closing press conference." Washington sanitary official told reporters the South, with the company's brand ambassador Fan Bingbing the opportunity to attend the Shanghai wind Shangsheng Dian, Washington hand Sina microblogging, start "Washington bathroom Y ES fashion" microblogging prizes forwarding activities, all of a sudden let "Washington" in nearly a thousand exhibitors stand out.

"microblogging control" the spread of magic be? Sina head home to the reporters, for example, joint public Sina home kitchen brand launched the "Energy Pioneer V action" to bring together the brightest show by Sina microblogging users own green living, green V of people do.

Roundtable

topic 1

market regulation, the situation is not clear, the brand break it is imperative?

Wrigley Marketing Director of Tan Yi

Wrigley present position? Where to go next? How to achieve change? The survey found that Wrigley's position in the minds of consumers, "good service, domestic popular brand", and the next development goal is to "set the whole package of quality services and products that have affinity in the high-end fashion brand, a strong international feel of the brand. " How to achieve change? We think the key is innovation, increase research and development, and integrate communication, to tap the core driver of consumer bathroom.

Ke Lani Home Marketing Director Zhu Chunyun

some extent, the situation is not that also means a lot of opportunities. Like 2008 and 2009 financial crisis period, the whole industry into a historical low, and Ke Lani was "sword pay" adverse economic expansion, with a very low cost of acquisition of the plant. Although the New Deal ferocious, but China's urbanization process has only just begun, the second and third tier cities in the real estate market is booming, the pursuit of high-quality consumption "must be greater than supply." Ke Lani's strategy is "pure German brand positioning" for precision marketing.

topic 2

mad hit home kitchen industry, advertising the good old days have passed?

Wrigley Marketing Director of Tan Yi

mad drop in advertising on CCTV, high-pushing tactics may allow companies to play "night fame, "may" instantly collapse. " According to the marketing point of view, a reasonable integration of existing communication channels produced by the spread of results than the single channel of communication and dissemination of results. In the actual operation of the market, the diversification of consumer trends in kitchen has become increasingly evident, is the so-called "difficult to reach," we call home and abroad through the microblogging designers hold "exchange", by the designer to high-end consumer groups population, again spread layer mass consumers, "environmental protection, fashion laptop bag concept", the effect is more obvious hand.

SSWW sanitary assistant to the chairman, Yang, director of marketing

brand management without advertising, but advertising does not mean you can hit good brand. In fact, many companies drop the purpose of advertising is to "drive sales", and waves whales that for marketing to expand a business investment is limited by "advertising" to launch a short-term business growth, it is better to rely on "product promotion", do really do go through the second and third tier cities healthy.

constant cleaning sanitary marketing director Liang Jiansheng

you into a misunderstanding, that your beauty, celebrities can come to lift the brand image, in fact, is the basic business competition, that is, the ability to integrate resources. Many people think that celebrity endorsements from the constant cleaning bathroom done, but in fact not so simple, Pu Cunxin indeed very consistent with our brand image, he is more intelligent, loving star, our brand image and brand meaning and he is quite fit, two who find a meeting point, it only took a few million endorsement fee. But in fact in order to promote the brand, so consumer awareness constant cleaning, we invested an astronomical amount.

topic 3

low carbon environmental protection is a "gimmick" or "trend"?

taitao Marketing Manager Qiuai Bin

environmental protection, including low-carbon are now becoming the focus of the entire country and the world, but that's easy as it sounds more difficult. Last year, in the event of ceramic enterprises found pneumoconiosis, but we have none of the cases the factory case occurred, including the Shanghai exhibition, our slim bathroom cabinet, raw materials are environmentally friendly, you can also save material, this is another manifestation of environmental protection. So we have been doing environmental protection this.

constant cleaning sanitary marketing director Liang Jiansheng

I think the bathroom and water-related industry is China's water shortage is a big country, is a big country of scarce resources, economic development in the past 30 years , we get the achievements but also as unconventional development has brought some problems. Now the so-called low-carbon green, more from national standards, and the second is that a sense of responsibility from the business to start, really convey to consumers, if the standards have, to a sense of responsibility of enterprises, Consumers will have direct experience of low-carbon full lace wig , whether your brand may be more low-carbon environment is business you do, then you can support live with you, I accept your point of view, there is the impression of your brand better understanding.
