4. Barrier and reflection layer: ensure that the foam material does not enter the inorganic hard high temperature resistant layer; reflect part of the heat of the high temperature resistant layer. 5. Inorganic hard insulation layer: high temperature resistance, ensure the interface temperature between the insulation layer and the foam, ensure that the foam will not be carbonized. Steel sleeve steel insulation pipe is made of conveying medium, working steel pipe, foam insulation layer and polyethylene plastic outer protection pipe, which are combined outward through the equipment in turn. Polyurethane insulation layer its function is waterproof, the second is heat preservation, overhead prefabricated steel sleeve steel steam insulation pipe remarks, the third is to support the weight of the heating network.

Aside from its practicality, the use of bamboo in this storage organizer provides an aesthetic appeal. The natural grain and warmth of bamboo add a touch of elegance and sophistication to any space. Whether you decide to keep it hidden away in your drawer or display it proudly on your wall, this bamboo plastic bag storage organizer blends seamlessly with any decor, adding a touch of eco-friendliness to your living space.

According to the different sliding mode, the thermal insulation structure of steel sleeve and steel composite thermal insulation steel pipe can be divided into two categories: inner sliding type: thermal insulation structure consists of working steel pipe, aluminum silicate, drag reduction layer, microporous calcium silicate, heat insulation layer, stainless steel fastening steel strip, aluminum foil reflection layer, polyurethane insulation layer, outer steel pipe, outer anti-corrosion layer. The inner sliding type thermal insulation steel pipe is composed of steel pipe composite silicate or microporous calcium silicate rigid polyurethane foam plastic jacket steel pipe glass steel shell anticorrosive protective coating structure. The quality is reliable.

Fiber reinforcement is an important method for plastic modification. Magnesium salt whisker and glass fiber can effectively improve the comprehensive properties of polypropylene. Polypropylene reinforced with glass fiber has the advantages of low density, low price and can be recycled. It is gradually replacing the application of engineering plastics and metals in automobile dashboards, car bodies and chassis parts: compared with glass fiber, the molded products of magnesium salt whiskers have higher precision, dimensional stability and surface finish, and are suitable for the preparation of various complex parts. Light and high strength flame retardant components and electronic and electrical components. As a modifier, magnesium salt whisker can greatly improve the strength, stiffness, impact resistance and flame retardancy of polypropylene. Therefore, more and more attention has been paid to the application of magnesium salt whisker and glass fiber in the modification of polypropylene. [1]

News: PP Taiwan Chemical K8065 original package price Shantou plastic doors and windows are made of polymer synthetic materials, supplemented by reinforced materials, made of a new type of material doors and windows. At present, three kinds of plastic doors and windows have been developed in the world: polyvinyl chloride (pvc) plastic doors and windows, glass fiber reinforced unsaturated polyester (GUP) plastic doors and windows and polyurethane (PUR) rigid foam doors and windows. Among them, polyvinyl chloride plastic doors and windows account for more than 90%. Therefore, this book mainly introduces PVC plastic doors and windows. Plastic is a poor conductor of electricity, heat, sound and so on, and its sealing performance is excellent, so it can be matched with air-conditioning facilities in cold winter or hot summer to achieve the effect of cold heat preservation and heat prevention.
