Not come to corundum Shi Cheng is burned board be out of shape case study
From;    Author:Stand originally
Not come to domestic corundum Shi Cheng is burned board the market uses a case; Domestic corundum not comes Shi Cheng is burned board manufacturing technology had a breakthrough eventually; Came true to need not depend on abroad to import again bear burn board condition; Limited company of new material of pottery and porcelain of state of luck of domestic Jiangsu Suzhou is already unripe yielded to be able to be overcome bear burn board rupture, bent problem; Solved bear burn board it is difficult to purchase, purchase the issue with high cost;

As a result of electric frit corundum, the use temperature of electric frit Mo Laishi is higher, the working temperature of two kinds of material all is in 1650 ℃ above, add right bear burn board of product framework reasonable deserve to compare, repass suppress, high temperature is firing; The production methods a future life that a few fireproof data companies of domestic think to use a convention produces corundum Mo Laishi bear burn board, come out bear burn board the use that use temperature can satisfy 1650 ℃ certainly is changeless the condition of form; The corundum that result user in use often can discover home not comes Shi Cheng is burned board appear to rupture and curve two kinds of phenomena;
  
Bear burn board because coefficient of expansion and high temperature defy the result that breaks intensity to bring about,be out of shape is; Home bear burn board coefficient of expansion is in about 8 the left and right sides, the coefficient of expansion of foreign product is in 5.65 the left and right sides; Home bear burn board high temperature is fought fold intensity to be in 8.5-10; abroad bear burn board high temperature is fought fold intensity to be in 13.5- - 14.5; is reduced only accordingly bear burn board coefficient of expansion can be reduced or prevent bear burn board rupture and bend be out of shape rate; The corundum that limited company of new material of pottery and porcelain of state of Jiangsu Suzhou luck produces craft production to go out through considering to improve for years not comes Shi Cheng burns board 1400 ℃ high temperature fights fold intensity to be able to achieve: 13.5Mpa; Particular branch is 1, radical of pottery and porcelain piece stroke smooth special; 2, radical of pottery and porcelain piece agglomeration, alumina, zirconia pottery and porcelain, electronic pottery and porcelain is special; 3, bear heavy-duty bear burn board 3 kinds of series; Abroad a few bear burn board produce manufacturer general bear burn board different use situation did careful cent to list: Cent is folded to fight model and defy a turn model; Solve those who be out of shape the problem can expect through matrix to allocate, strict manufacturing technology, reasonable pressure will reduce coefficient of expansion and raise tall Wen Kang to lose strength, satisfy all sorts of different use condition thereby.
