The raw material of glass fiber reinforced plastic is divided into two kinds: reinforced material and base materialThe reinforced material of glass fiber reinforced plastic is composed of glass fiber and its fabric. It is the main load-bearing component material of glass fiber reinforced plastics, and has a direct impact on the strength and stiffness of FRPs
The main raw materials of flat glass are: silica sand (sandstone), sodium carbonate, feldspar, dolomite, limestone and mirabilite. Process: 1, raw material crushing: the raw materials are crushed into powder; 2, weighing: according to plan the list of ingredients said powder can take a certain amount of; 3, will be called: the mixed powder mixing, stirring into a batch (colored glass and colorant);s
The disadvantages are complicated operation, great difficulty, slow curing time, and difficult to meet the requirement of mass production. The general characteristics and one component adhesive is fast and can meet the requirements of mass production process, product defect is after bonding of the bubbles, easy white, poor weather resistance, beautiful appearance and poor quality. In addition, the adhesive bonding process skill is also very important, there are several common a, docking: acrylic plate the level of two block to be docking on the operating platform, closed, and at the bottom of a sticky tape, leaving a gap of not more than 0.3mm wide for coating adhesive injection.s
The main chemical composition of glass products is silicon dioxide, sodium oxide, calcium oxide and other inorganic compounds, the precipitates of tableware national limit has strict rules, regular production of glass tableware, kitchenware is not harmful to humans, so consumers do not have to worry about the basic glass tableware utensils will cause harm to food safety. Daily exposure of glass tableware from the material can be divided into sodium, calcium, glass, that is, ordinary glass, borosilicate glass, lead crystal glass, glass ceramics.s
First of all, you know what zircon sand is[g o], also known as zirconium sand zircon sand, zircon, is a kind of zirconium silicate (ZrSiO4) as the main mineral composition. Zircon sand pure colorless transparent crystal, often because of quantity and species of different origin and different impurities dyed yellow, orange, red and brown color, crystal structure belongs to tetragonal, a square pyramidal column, the proportion of 4.6 to 4.71, the proportion of the variation with composition and sometimes altered state with zirconium stone incomplete cleavage, uniform Mohs hardness of 7 to 8, the refractive index of 1.93 to 2.01, with the melting point of impurities in different 2190~2420 DEG C wave. The main chemical composition is ZrO2, SiO2, and a small amount of impurities such as Fe2O3, CaO, AI2O3 and so on. The theoretical composition of zircon sand is ZrO2:67.1%; SiO2:32.9%. It is the only compound in the ZrO2-SiO2 system. But natural zircon sand contains only about 57~66%ZrO2.s
The typical phenomenon of the failure of insulating glass products is that the condensation and water inflow in the insulating glass interlayer affect not only the appearance of the whole glass, but also the thermal performance of the whole glass.s
