]]> Causes and preventive measures of oxidation of coated glass film http://en.jlblkj.com/show.asp?id=97 Oxidation after coating glass coating: It means that Low-E glass is oxidized after the coating is completed because the silver in the film is contaminated by moisture or sulfide in the air. Mainly caused by the following reasons:


(1) The air humidity during production is too high, and the water content in the air is too high, especially during the rainy season. In the south from May to October each year is the season of easy oxidation of Low-E glass. In view of this situation, on the one hand, a sufficient amount of desiccant should be charged when the lower film is packaged, and on the other hand, the time for waiting for hollow production should be shortened as much as possible.

]]> There are several production methods for coated glass. Do you know? http://en.jlblkj.com/show.asp?id=96 1. Vacuum evaporation coating: The vacuum coating machine using thermal evaporator produces coated glass. Because the overall production is intermittent, some of the cleaned glass often needs to wait in the workshop for a period of time before coating the coating chamber. At this time, The glass will be subject to secondary pollution, causing the film layer coated on the contaminated part to fall off easily, the uniformity of the film layer is poor, the rainbow color difference and the reflectivity are easy to be high. Jinhua tempered glass manufacturer, and the glass is only coated with a film, which is easy to It is discolored in the air and cannot produce large-size glass. Therefore, the Ministry of Construction has made clear that such coated glass is not easy to be used as curtain wall glass. In China, it can be seen that the curtain wall glass of many buildings appears white around each piece of glass, black in the middle, and stripping of the stripe is caused by the wrong selection of the coated glass. Of course, the price of such glass is generally low at 80 yuan to 100 yuan / m2. Individual decoration companies have chosen such glass pits to swindle users. Jinhua fire glass customization


2. Vacuum magnetron cathode sputtering method: flat glass in a vacuum chamber with high vacuum, working gas positive ions between the two poles of negative voltage fly to the cathode under the action of orthogonal electromagnetic field, in a short cathode position A large amount of energy is obtained in the drop zone to rapidly bombard the target, so that the cathode (target) atoms fly toward the glass substrate-glass deposition film, and the sputtered secondary electrons (this process is called γ process) act in the electromagnetic field. Pressing the rotation of the rotary wheel to participate in the impact ionization, the crabs are the carriers, so that the energy source continuously bombards the cathode, providing a sufficient amount of positive ions Jinhua fireproof glass, forming a plasma zone to sustain the glow discharge, which can be completed at one time. Layer coating with excellent film uniformity, excellent edge coverage and good adhesion. What is particularly mentioned here is the coating machine produced by the German "LH" company. The advantage is that it is superior to and different from other vacuum magnetron sputtering coating machines: the magnetic field on the planar magnetron target is generated by the ring magnet. Jinhua tempered glass manufacturers can regard the semi-circular ring magnet as a combination of infinite T micro-fan column magnets. Therefore, the corresponding magnetic label potential is relatively stable, in order to produce a uniform and firm coating layer.


3, solution gel method: also known as double-sided coating impregnation method, the coating method is to immerse the glass in a chemical solution, forming a film on the surface of the glass, the chemical film layer adheres to the surface of the glass, the film thickness can pass 50% of the incoming rays, the rest reflected off, and absorbed little light.

]]> Study on two-component polyurethane sealant for insulating glass http://en.jlblkj.com/show.asp?id=81 Insulating glass is a new type of building material with two pieces (or three pieces) of glass, which is bonded with an aluminum alloy frame by using high-strength and high-air-tight composite adhesive. It has good heat insulation, sound insulation and beautiful appearance. . Insulating glass units usually use two-way sealant, that is, polyisobutylene rubber is used as the first seal, and organic silica gel, polysulfide rubber or polyurethane glue is used as the second seal. In this paper, two-component polyurethane sealant for insulating glass was prepared by using hydroxyl-terminated liquid polybutadiene and crude MDI as main raw materials, and the filler, plasticizer, chain extender, adhesion promoter and catalyst pair were studied. The effect of the glue properties.


Experimental materials: hydroxyl-terminated liquid polybutadiene, Poly bd® R45V, Crayville (Guangzhou) Chemical Co., Ltd.; crude MDI, WANAATE® PM-200, Wanhua Chemical Group Co., Ltd.; nano calcium carbonate, WINNOFIL® SPM, SOLVAY; heavy calcium carbonate, OMY-2, Omega (Shanghai) Investment Co., Ltd.; plasticizer, DIDP, ExxonMobil Chemical; chain extender, 1,4-butanediol (1,4- BDO), Shanghai Tishhi Ai; adhesion promoter, Silquest® A-187, Momentive Advanced Materials (China) Co., Ltd.; catalyst, ZJPC-0225, homemade.


(1) The effect of NCO/OH ratio on the performance of insulating glass sealant: Generally, the closer the ratio of NCO/OH is to 1, the closer the sealant is to the gel point, the faster the reaction cross-linking speed, but too fast. The crosslinking speed affects the operability of the polyurethane sealant. Therefore, the selection of the appropriate NCO/OH ratio is crucial for the two-component polyurethane insulating glass glue. The performance of the two-component polyurethane insulating glass sealant was investigated by comparing different NCO/OH ratios. The results are shown in Table 1 and Figure 1 shows.

]]> How many kinds of main and auxiliary materials are used in glass, and what role does it play in glass manufacturing? http://en.jlblkj.com/show.asp?id=80 First, the main raw material of glass Jinhua fireproof glass


1. Borax or silica sand: The main component of borax or silica sand introduced into glass is boron oxide or silicon oxide, which can be separately melted into the main body of glass during combustion, which determines the main properties of glass, correspondingly called borate glass or Silicate glass; Glauber's salt or soda ash, the main component of Glauber's salt and soda ash introduced into glass is sodium oxide, which can form a fusible double salt with an acidic oxide such as silica sand during calcination, making the glass easy to form. However, if the content is too much, the glass thermal expansion rate will increase and the tensile strength will decrease. Jinhua fireproof glass


2. Feldspar, limestone, dolomite, etc.: The main component of limestone introduced into glass is calcium oxide, which enhances the chemical stability and mechanical strength of the glass, but too much content will also reduce heat resistance and glass crystallization. As a raw material for the introduction of alumina, feldspar can control the melting temperature and has high durability (in addition, feldspar can also provide potassium oxide component to improve the thermal expansion property of glass), and dolomite is used as a raw material for introducing magnesium oxide. It can improve the transparency of the glass, improve the water resistance and reduce the thermal expansion. In general, glass is not made entirely from new raw materials, but 15%-30% broken glass is blended. Wenzhou fire glass customization
