Brief analysis on the development of GFRP resin industry in China
With the increasing maturity of basic research technology of FRP and the continuous introduction of advanced equipment and technology from abroad, the domestic FRP industry has been developing rapidly in recent years, and the variety of gel coat resin has been expanding constantly. Gel coat resin in the continuous increase of variety and performance, kept expanding its application field, current gel coating in sanitary ware, tub, the counter, etc., such as shower tub shipbuilding industry such as yachts, lifeboat, patrol boats and transportation industry, construction industry, the entertainment industry, medical instruments, billboards, kiosks and security kiosks and many other fields have been applied. Gel coat resin divided into color and color gel coat. In the production process, the vast majority of cases need to use color gel coat. In the past, coloured plasters were made by adding appropriate color paste (also called pigment paste) into the ecru plasters. The colouring paste thus prepared is often used in large assembly products, such as cooling tower or mass production, such as seats on the viewing platform in the playground. In order to overcome this drawback and improve the product appearance quality, we need to produce color gel coat without color difference for customers. The development of low styrene bulk gel coat resin is very necessary and has very important practical significance.
At present domestic enterprises can produce color suits is not much, ashland polyester (kunshan) co., LTD is China's largest color gel suppliers, ashland company in order to provide faster, more timely service to suits, all over the world (including ashland polyester (kunshan) co., LTD.) launched INSTINT rapid gel automatic production system, can be in a few minutes for the customer to produce the required color color glue; Jinling disman company introduced the Eurotinter equipment of the world's most advanced automatic production line of color adjustment and color matching for color overalls with annual output of 1000t from the DSM headquarters (owning the world's largest undergarment factory), which is the 5th production line of color overcoats in the world. Jiangsu fuling chemical co., LTD. (formerly jiangsu fuli chemical co., LTD.) has also introduced an advanced production line of color gel coat with all-computer adjustment and color matching from Holland. Large state-owned enterprises tianma group (has a great influence on the domestic FRP industry) as well as the meaning of chemical (Taiwan's largest gel manufacturer, until one of the main rubber clothing suppliers in Asia, southeast Asia Taiwan solely invested enterprise) in the production of color gel coat color system USES the world's most advanced computer color, toning, again through the personnel to the greatest extent eliminated due to the different batches of the paste off color.
The matrix of the resin is unsaturated polyester resin (UP), so most enterprises producing UP produce the resin. According to incomplete statistics, the annual sales volume of the gel coat in China in 2001 was about 20,000 tons, among which the color gel coat was over 3,000 tons. In recent years, the annual sales volume of all enterprises is mostly increased by 10% ~ 30%, and the growth trend is not decreased, so there is a great potential in the gel garment market. Although the market prospect is very good, still very fierce competition, to gain a foothold in the industry, need to have enough economic strength to occupy the market, best quality and or have a unique product, glass steel mills named bei gel year sales volume is not too big, but it has gas dry gel, radiation curing, gel coats, as well as the hit not bad mold gel features such as gel in the leading position in the industry, profits are still considerable; Meaning of chemical industry the development and production of a kind of SMC paste, resistant to high temperature of 180 ℃ and the surface is design and color of the products, successfully applied in big central air conditioning. Gel coat resin is the production of glass - reinforced plastic coating of special resin. Styrene is still the most suitable monomer for UP resin. At room temperature, however, the vapor pressure of styrene is higher and more volatile, especially for GFRP products made by hand paste or spray molding, and more volatile in the process of its coating and backing enhancement. a.
