Product Introduction

Announce

edit

Ultrafine glass wool is mainly made of quartz sand, feldspar, sodium silicate, boric acid, etc Thermal insulation material 。 After melting at high temperature, the fiber cotton less than 2um is obtained, and then the thermosetting resin adhesive is added to pressurize and finalize at high temperature to produce board, felt and pipe products of various shapes and specifications. The surface can also be pasted with aluminum foil or PVC film. The product has light volume weight, small thermal conductivity, large absorption coefficient and good flame retardancy. It can be widely used in thermal equipment, air conditioning constant temperature, cold and hot pipes, oven drying room, cold storage and preservation, and building insulation, heat insulation, sound insulation, etc.

glass fibre

edit

superfine glass fibre It belongs to one type of glass fiber and is a kind of artificial Inorganic fiber 。 Imported equipment and American technology are used. Broken glass is used as the main raw material, together with some soda ash, borax and other auxiliary materials, and the molten glass is centrifugally blown into cotton like glass microfibers with a diameter of 2.5 to 5 μ m, commonly known as glass wool. The fibers are vertically intertwined with each other, with a large number of internal and external micro pores and holes, so they are considered as porous materials, It has the advantages of light constitution, low thermal conductivity, good thermal insulation and sound absorption performance, incombustible, corrosion resistant, non-toxic, not afraid of moth eaten, not stabbing the skin, high water repellency, and good chemical stability Sealed Lead Acid Battery It is an ideal material for glass fiber adsorptive partition, filter paper and thermal insulation paper, and is also the preferred material for VIP (vacuum thermal insulation board). It is recognized as an ideal material for heat preservation, sound attenuation and heat insulation with superior performance.

Glass core material

Announce

edit

Glass core material is an important part of VIP Vacuum insulation plate The thermal conductivity of the core material after vacuum pumping plays a crucial role. The core material has a certain strength and can play the role of skeleton support. The fiber distribution of the core material plays a decisive role in the insulation of VIP. It can be seen that the fiber distribution of the core material is more uniform. The lower its thermal conductivity, the better its thermal insulation performance.
