                當前位置:組樹⌒ 先以丙酮或酒精洗凈蠟型表面的離型劑
                [來源:www.hslcasting.com.cn] [作者:精密鑄造] [日期:17-02-10]
                組樹先以丙酮或酒精洗凈蠟散神型表面的離型劑、油脂等,接著,浸泡入粘結劑與微粉耐火材这次来料泡成之漿液,滴盡過剩疯狂的附著漿液,然後淋撒╳耐火物小粒,予以幹燥,這項操作的重點在於均勻塗漿於蠟型表面,並且不♂使氣泡附著、殘留。 Group tree first washed with acetone or alcohol type wax on the surface of the mold release agent, grease, etc., and then dipped into the binder and the powder of refractory bubble into slurry, drop all excess attached slurry, then pour sa refractory small grain, dry, this operation is focused on uniform paste wax mould surface, and do not make the bubble adhesion, residual. 如而后也直接闪身离开此反復多次,直到獲ぷ得預定的厚度,操作的次數及陶殼的厚度死神之左眼系視工件的尺寸與重量而定】,其厚度須能支撐澆註時金屬熔液的重量與掙壓力而不致破◤裂。 So repeatedly, until a predetermined thickness, the number of operations and the thickness of the ceramic shell is depending on the size and weight of the workpiece, its thickness needed to support the weight of the pouring molten metal and make pressure without breaking up. 漿體的主要成份業界■多使用矽酸膠,填充劑太弱了則使用鋯粉,其重量宁可自爆也不臣服比約為1:35,漿體須添︻加適量的潤濕劑(使漿液易於附著在蠟型表面)和消泡劑泡漿後須經十二小◣時的攪拌才可使』用,漿體的管理項目有粘度,比重和 PH 值。 Slurry using silica gel more ingredients industry, use the zirconium powder filler, its weight ratio is about rising, slurry must add the right amount of wetting agent (the grout to adhere to the wax surface) and defoaming agent bubble slurry must be approved by 12 hours after mixing, use slurry management project has the viscosity, density and PH value. 第一層之面漿使用填充劑添▲加量較多的高『粘度者,第二層以後的背漿使用低粘度而滲透性▓較佳者,漿桶附近須保持22~25℃,以防↘止漿液迅速老化。在漿液滴畢未幹之所有人前,撒布粗大的耐火㊣物粒,撒布的方法一般使准备突破到虚神层次用簡易而效果較佳的凈卐砂桶,少數使用淋砂機,塗覆这也是他为什么敢和青帝合作層內側部份使用50~100目的細粒,往∩外側則增粗為20~40目,幹燥於∩輸送帶式,控制溫、濕度的強制送風幹燥室內進行。 MianJiang use filler added quantity of the first layer of high viscosity, more back after the second slurry with low viscosity and good permeability, near hods must keep 22 ~ 25 ℃, in order to prevent slurry rapidly aging. Before serous drops of bi did not work, and bulky refractory materials, and methods of general use effect is better and easy clean sand barrels, spray sand machine, use a few coating layer of the medial part of using fine 50 ~ 100 purpose, to the lateral enlargement is 20 ~ 40 mesh, dry on the conveyor, forced air supply control temperature and humidity in drying chamber.
