Abstract
An antifog glass is made up through such technological steps as spreading transparent ethyl vinylacetate resin film and electrothermal wire between two layers of float glass, vacuumizing the space between them, heating and cooling. Its advantages are simple process, no need of preheating and high-pressure heating and low energy consumption.
Description
The present invention relates to the production and processing method of glass, more specifically be meant a kind of antifog glass preparation method who utilizes the nichrome wire conductive exothermal.
Traditional antifog glass preparation method who utilizes the nichrome wire conductive exothermal is with in nichrome wire and the two-layer float glass of PVB (polyvinyl butyral resin molding) intermediate coat folder people, get rid of air in the laminated glass with roll extrusion or in the mode that vacuumizes, then it is carried out preheating, precompressed, be preheated to 100, be depressed into 1KG/cm in advance
2Deliver to heating in the pressure furnace, pressurization after preheating, the precompressed again, be heated to 120-150 degree Celsius, be forced into 12-15KG/cm
2, cool off again, become finished product after the cooling, be antifog glass.This working method is lasted 2-3 hour, and its process is very cumbersome, complicated, and big energy-consuming, reaches 2.5K.W.H/M approximately
2, the antifog glass that is one square metre of every processing will consume 2.5 kilowatt-hours.
For this reason, the objective of the invention is the shortcoming that exists at above-mentioned traditional antifog glass preparation method, propose new a kind of antifog glass preparation method who utilizes the nichrome wire conductive exothermal.
To achieve these goals, the present invention adopts following technical scheme: transparent ethene ethyl acetate resin molding and nichrome wire are lain against in the middle of the two-layer float glass, through vacuumizing the air of getting rid of in the two-layer float glass; Reheat is to 80-120 degree Celsius; Cooling.
Because the present invention selects for use ethene ethyl acetate resin molding and nichrome wire to lie against in the middle of the two-layer float glass, through vacuumizing the air of getting rid of in the two-layer float glass, reheat just can obtain utilizing the antifog glass of nichrome wire conductive exothermal to the 80-120 degree Celsius, therefore, compare with traditional method, this procedure is simple, has save pre-heating step and need not under high pressure to heat; The method applied in the present invention power consumption simultaneously is also few, can reach energy-conservation purpose.
Below in conjunction with drawings and Examples, the present invention is described in further detail:
Fig. 1 utilizes one of antifog glass structural representation that the inventive method makes.
Fig. 2 utilizes two of antifog glass structural representation that the inventive method makes.
See also Fig. 1,
Embodiment 1, the inventive method at first with transparent ethene ethyl acetate resin molding as intermediate coat, this intermediate coat and nichrome wire 2 are lain against two-layer float glass 1 centre, then through vacuumizing the air of getting rid of in the two-layer float glass, reheat is to 80 degree Celsius, after finish whole process after the cooling.
The effect of wherein transparent ethene ethyl acetate resin molding has two, the one, nichrome wire is glued between the two interlayer float glasses 1, other is to be an integral body with two-layer float glass 1 gummed, whole process of preparation only needs about 1 hour, and traditional preparation method needs 2-3 hour, utilizes method power consumption of the present invention only to be 1.25K.W.H/M
2, reach more than 1 times than original method is energy-conservation.
See also shown in Figure 2, the conductive interlayer heating antifog glass of made and a float glass 3 that does not paste the demist plastics film are again carried out hollow processing, between said conductive interlayer heating antifog glass and the said float glass 3 that does not paste the demist plastics film edge with aluminum pipe and siccative 4 mutually barrier fix.So just be made into the antifog glass that utilizes the nichrome wire conductive exothermal of hollow.
The thickness of above-mentioned float glass 1,3 is all between 3mm-5mm.
