Abstract
The invention discloses an arch micro-crystal glass preparing method and specific mould, which comprises the following steps: manufacturing flat-shaped micro-crystal glass hair plate; placing on the specific mould; pushing in the kiln to bend; heating at 1-3 deg.c per min; insulating at 750-820 deg.c for 0.5-1.5h; cooling at 1-2 deg.c per min; grinding; polishing; cutting into the product.
Description
Technical field
The present invention relates to building material technical field, especially relate to manufacture method of circular arc type glass-ceramic and particular manufacturing craft thereof.
Background technology
The production technique of devitrified glass has two kinds of methods: a kind of is rolling process, and a kind of is sintering process.It is bigger that rolling process is produced investment, and range of product is difficult to variation, the similar pottery of the devitrified glass of producing, and decorative effect is not good, so adopt sintering process to produce the more of devitrified glass.The technological process that sintering process is produced microcrystal glass plate is, after at first mineral powder, industrial chemicals etc. evenly being mixed by prescription, drop in the glass melter and melt, the glass particle of certain particle size is made in shrend, then glass particle is put into mould with releasing agent, sintering and crystallization in crystallization kiln, at last that crystallization is good microcrystal glass plate are ground, throw, are cut and be processed into product.
But, adopt sintering process to make circular arc type glass-ceramic and need increase a processing step, the devitrified glass hair of exactly crystallization being finished is dull and stereotyped through after the roughing, be placed on the ready-formed arc groove mould, form circular arc type glass-ceramic through Overheating Treatment, qualified product through explained hereafter such as overground, as to throw, cut.Prior art is in heat treatment process, and the way that more employing is exerted pressure on devitrified glass hair flat board is accelerated to be shaped, and the shortcoming of this processing method is that the finished product rate is low, the mould volume is big in addition, the absorption heat is many, wastes energy, and the intact back of thermal treatment cooling rate is slow.
Summary of the invention
The objective of the invention is to overcome the deficiency of prior art, the manufacture method of simple, the with low cost and circular arc type glass-ceramic that yield rate is high of a kind of technology is provided.
The present invention also provides a kind of particular manufacturing craft of making the circular arc type glass-ceramic method, this mould has that volume is little, heat absorption less, advantage such as rapid heat dissipation.
Manufacture method of circular arc type glass-ceramic of the present invention, with crystallization forming is that flat etched microcrystalline glass plate is through roughing, be placed on the mould, push and carry out the hot bending processing in the stove, speed with 1～3 ℃ of per minute heats up, 750 ℃～820 ℃ insulations 0.5～1.5 hour, then with 1～2 ℃ of cooling rate cooling of per minute, cool to room temperature and come out of the stove, through overground, throw, cut and produce qualified product.
The manufacture method of circular arc type glass-ceramic of the present invention, carry out hot bending and handle more that optimized parameters is in stove: the speed with 1.5～2.5 ℃ of per minutes heats up, 770 ℃～800 ℃ insulations 0.8～1.2 hour, then with 1.2～1.8 ℃ of cooling rate coolings of per minute.
Produce circular arc type glass-ceramic and generally adopt CaO-Al

20～0.5 part of O, B
2O
30～5 part, tinting material are an amount of.
Described tinting material is little with the relation of making circular arc sheet material in this prescription, can select tinting material as required arbitrarily, as: cream-coloured tinting material NiO, blue colorant CoO+CuO, gray colored agent NiO+CoO+Fe
2O
3Its proportion in starting material is about 0.01～0.2%.
In order to produce circular arc type glass-ceramic, improve yield rate and save the energy, improve the quality of products, the present invention has also designed the manufacture method of circular arc type glass-ceramic particular manufacturing craft, this mould is by stainless steel pillar sheet, stainless steel tube, vitrified pipe and stainless steel iron sheet are formed, described stainless steel is a kind of heat-resisting oxidation-resistance Cr-18Ni-9Ti material, there is the stainless steel pillar sheet of half garden v notch v to link into an integrated entity by some stainless steel tubes with 3～5, arrange steel pipe in 1: 3～6 ratio and vitrified pipe forms half garden groove in indentation, there, on groove, place the stainless steel iron sheet that bends to circular arc.
The invention has the advantages that: adopt the softening naturally forming technology of high temperature, need on devitrified glass hair flat board, not exert pressure, manufacture method is simple, do not need complicated die just can produce, topmost in addition still firing period is short, finished product rate height, the circular arc type glass-ceramic integrated yield that adopts this method to produce reaches more than 90%.Particular manufacturing craft is made by heat-resisting oxidation-resistance steel and two kinds of materials of pottery, simple and practical, because die design uniqueness, in using repeatedly, indeformable at arc direction and generatrix direction, finished product reaches the arc raw sheet of expection accurate size always, and it is also advantageous in that the mould volume is little in addition, heat absorption less, rapid heat dissipation, the saving energy, shorten the process time.
