Abstract
The invention relates to microcrystalline glass, which belongs to a high-grade novel decorative material. The glass uses a natural inorganic material, adopts a specific control technology, and is manufactured by separating out special crystal phase in molten glass containing special components through a specific production technology. A microcrystalline stone can be used for decoration of internal walls, external walls and floors of various buildings, and is even an ideal material for a wash bedplate and a sanitary bedplate. However, the prior sintered microcrystalline glass is manufactured by melting and sintering twice, so that not only energy consumption of a fuel is high, but also a blank product has rough surface and high air porosity, thereby causing high secondary processing energy consumption and cost, and affecting thinning development trend of the microcrystalline glass. The microcrystalline glass is manufactured into a decorative plank by a floating (rolling) method, so indexes of the microcrystalline glass such as shock strength and compressive strength are superior to those of the sintered microcrystalline glass, and physical-chemical properties and decorative effect are superior to those of a natural stone. The thinning microcrystalline glass achieves continuous production, high efficiency and low cost. Because large-scale thinning of the product, the production process saves energy consumption, and is environment-friendly. Compared with the production line of the sintered microcrystalline glass plank with the same scale, the production process can save fuel oil by more than 50 percent.
Description
The present invention relates to a kind of processing method of thin type nucleated glass wall surface decorative plate.
Devitrified glass has been concentrated triple advantages of glass, pottery and lithotome, be better than lithotome and pottery, can be used for external wall and indoor high-grade the decoration, also can do structured material mechanically, insulating material on electronics, the electrician, the baseboard material of large-scale integrated circuit, microwave oven flameproof ware, chemical industry and impregnating material and mine high-abrasive material or the like.It is type material with 21 century of development prospect.
Devitrified glass belongs to high-grade emerging finishing material, and it is with the natural inorganic material, adopts specific controlled process, separates out special crystalline phase in the glass metal of special composition, makes through specific production technique.Devitrified glass can be used for the interior exterior wall and the floor decorative of all kinds of buildings, the ideal material of the platen of washing one's face especially, health platen.But existing sintering process devitrified glass is made through twice molten sintering, and this not only makes the fuel energy consumption high, and the blank product surface is coarse, the void content height causes high secondary processing energy consumption and cost, and has influenced its slimming development trend.The float glass process microcrystalline glass decorative plate, indexs such as its resistance to impact shock, compressive strength are better than the sintering process devitrified glass, and physicochemical property and decorative effect all are better than lithotome.Being constructed and put into operation of thin type nucleated glass production line can be reduced significantly to the exploitation of the blindness of lithotome, and production itself economizes on resources, reduces energy consumption, protected resource effectively.
The float glass process thin type nucleated glass wall surface decorative plate is by the improvement of production technology and equipment, and indexs such as its resistance to impact shock, compressive strength are better than the sintering process devitrified glass.The thin type nucleated glass that the float glass process technology is produced can be realized continuous production, the efficient height, and cost is low.Because the extensive slimming of product makes production process energy-saving and cost-reducing, environmental protection.Compare with the sintering process crystallizing glass sheet material production line of same scale, can save fuel oil more than 50%.
Floating process is the effective way of producing thin type nucleated glass, and this production technique is produced continuously, the production efficiency height, and production cost is low, and is energy-saving and cost-reducing.It is the desirable replacement technology of sintering process devitrified glass.Because crystallizing glass sheet material is compared with lithotome and is had "dead" harm and economize on resources, doing one's utmost to praise highly the China of green product now, it produces the positive support that will be subjected to national relevant industry policy with development.
Float glass process nucleated glass wall surface decorative plate of the present invention, at first carry out specific glass composition, nucleus agent and microcrystalline technology, the efficient nucleus agent of selection superfine nano attitude, in float tin groove, finish glass-ceramic process, thereby when forming the high strength micro-crystalline glass material, avoided the distortion of sheet material.The glass metal that fusing is good flows into the calendering formation machine from overflow port through the holder brick, glass after the moulding enters process furnace after moving roil table is lowered the temperature naturally, when being heated to certain temperature, enter the molten tin bath crystallization, be full of nitrogen and hydrogen in the molten tin bath space, avoid the tin liquor oxidation, after glass ribbon is heated to about 850 ℃, carrying out micritization behind the insulation certain hour handles then through cooling gradually, gone out molten tin bath by drawing,, enter annealing furnace through the transition roller platform.Its flow process is as follows:
Disconnected → the air cushion of glass melter → calendering formation → molten tin bath → micritization → moving roil table → annealing furnace → slitter → transverse cutting unit → manually break off with the fingers and thumb is got plate → get plate → finished product
The float glass process devitrified glass is the senior building finishing material, have extraordinary planeness, surface gloss and good physical and chemical performance, alternative natural granite is used for interior exterior wall, ground and the table top of various buildings and decorates, applying of float glass process devitrified glass will form new growth engines, goes to the world with the advantage of high-performance quality, lower production cost, scale operation.Can adopt industrial residue to do main raw material (as gold ore tailing) in addition in the production of float glass process devitrified glass, be the environment-friendly type project; Also be that float glass factory adjusts the first-selected product innovation that structure is increased economic efficiency.
