On July 31, 2015, bach of Olympic committee chairman announces Beijing hand in hand Zhang Jia mouth is obtained Autumn 2022 of the Olympic Games hold advantageous position. Beijing makes the whole world from this the city that holds aestivate Olympic Games to will hold Olympic Winter Games again already. Produce actually in firebrick in, the main method that adds raw material plasticity has:
① choosing expects, eliminate among them blame plasticity impurity, wait like quartz;
② will be chosen makings is fine grind, increase its to be spent dispersedly;
③ adds bond of material of right amount plasticity, wait like pulp waste liquid, dextrin;
④ undertakes to pug vacuum squeezes provenance to manage;
⑤ extends tired makings time.
The combinative sex of raw material is to point to clay kind raw material and blame plastic raw material is united in wedlock, form plasticity mud group and have certain dry intensity capacity. The combinative sex that combines clay joins standard quartz with can forming the place when plasticity mud is round normally arenaceous (grain comprises 0.25 ～ 0.15mm to occupy 70% , 0.15 ～ 0.09mm is occupied 30% ) amount and dry after fight fold intensity to mirror. The clay with general strong plasticity, its union ability is strong also (also have exception, be like Nanning ball clay very pure and granuality is fine, plasticity is very good. But because the surface can be big adsorbed water is much, dry when dehydration systole is big, the cranny that produces causes dry intensity to differ more. Its plasticity index can amount to 36 ～ 47, and fight fold intensity to be 0.48Mpa only.
What Zhengzhou flourish Cheng Naicai serves as major is fireproof and pouring makings production manufacturer, product quality is good, price material benefit, welcome everybody the incoming telegram seeks advice and choose and buy.
