Using french chalk which was dried by the 120 air as the normal air model , the quality which the fabric contains particle can be test . considering the fabric ' s reusing , the author has washed the fabric in many ways and compared the washed and unwashed fabrics “ purifying performance testing datas . through putting the fabric on the home air condition , the author analysed the effect to the air condition ' s runing and purifying performance 為了將高效濾料進一步推廣使用,本文通過試驗,得到過濾速度和定量對過濾材料過濾性能的影響;利用120的高溫烘干過的滑石粉作為塵源,試驗得到該濾料的容塵量;考慮到濾料的重復使用問題,對濾料進行清洗處理,比較處理前后濾料的過濾性能測試結果,看能否對濾料進行清洗。

Please keep in mind that the titanium products should be cleaned by soft fabric or a litter french chalk , not by acid and alkaline detergent . for the plastic and non - stainless steel products , should not be used in the moist floor or cleaned by the water directly . and the brass products have done by oxygenation , so that you only want to clean by soft frabic 鈦金制品,切勿用酸、堿性清潔劑擦洗,只需用軟布或少許滑石粉擦之即光亮如新,非不銹鋼、塑料類產品不能使用在潮溫地面或直接用水沖洗;銅制品已做氧化處理,切勿使用擦銅劑,只需用軟布擦之即可。

We have developed the grain size varies among 2um to 15um grade superfine powder and the yearly output of which comes up to 20 , 000 tons . our products mainly consist of calcite powder , french chalk , active coarse whiting and other jinshi brand series superfine powder , which are welcomed in the more than 10 provinces and districts markets . the company has owned a calcite mine , and the calcite storage capacity has reached to more than 2 million tons 99年公司投資1500萬元引進細川德國alpine公司先進超細粉碎分級設備流水生產線,屬國內領先水平,開發了粒徑為2um - 15um級的超細粉體(年生產量2萬噸) ,主要生產方解石粉、滑石粉、硅灰粉、活性重鈣等金石牌系列超細粉體,暢銷國內10多個省市,產品深受各地用戶親睞。

Taking the brown alumina powder and french chalk as the refractory , the silicasol and dextrin as the composite binder , the western bentonite and sodium carboxymethyl cellulose ( cmc ) as the composite suspension agent , the optimum mixing ratio of the water - based coating was established by the method of orthogonal experiments 摘要選用棕剛玉粉及滑石粉為耐火填料,以硅溶膠及糊精為復合粘結劑,以鈉基膨潤土和羧甲基纖維素鈉( cmc )為復合懸浮劑,通過正交試驗方法確定了最佳配方。

The best technical condition of the reed pulp is in 47 sr , wipped off primary fines and added secondary fines up to 10 % , meanwhile , adding stuffings ( abietic acid , vitriolic aluminium , french chalk ) 漂白蘆葦漿抄造文化用紙的最佳工藝條件為:在打漿度為47 sr時去除一級細小纖維,加入10 %的二級細小纖維,同時加入填料(松香膠、硫酸鋁、滑石粉) 。
