燒過石灰石的煤渣還有什么用?能不能做地磚瓷磚原材料副料用,粉唰打底用,或做磚,或輕質磚用?:燒過石灰石的煤渣還有什么用?能不能做地磚瓷磚原材料副料用,粉唰打底用,或做磚,或輕質磚用?
類似產品(煤渣)的主(zhu)要成分是二氧化(hua)硅、氧化(hua)鋁、氧化(hua)鐵、氧化(hua)鈣(gai)、氧化(hua)鎂等。根(gen)據(ju)成分的不同,可用于制造水泥、磚和耐(nai)火(huo)材料等。
如:
1、制造砌筑(zhu)砂(sha)漿(jiang)和(he)墻體(ti)材(cai)料(liao):以(yi)煤(mei)渣細粒(li)為(wei)主(約占2/3),摻入適(shi)量粉煤(mei)灰(1/3左右(you)),另外(wai)再加10%左右(you)石(shi)灰,3%左右(you)石(shi)膏(gao),或加5~10%水泥,拌合(he)后制成(cheng)砌筑(zhu)砂(sha)漿(jiang)。也可用輪碾機濕碾成(cheng)砂(sha)漿(jiang),再利用成(cheng)型(xing)機制成(cheng)標準磚(zhuan)、空心磚(zhuan)和(he)小型(xing)砌塊(kuai)。
2、作(zuo)水泥(ni)(ni)混(hun)(hun)合材(cai)料(liao)(liao):煤(mei)渣為燒結火山灰質材(cai)料(liao)(liao),磨細后仍具有水硬膠(jiao)凝(ning)性能,可(ke)(ke)同水泥(ni)(ni)熟料(liao)(liao)、水泥(ni)(ni)或同石(shi)灰和石(shi)膏等配制加工成少熟料(liao)(liao)或無熟料(liao)(liao)的水泥(ni)(ni),其強度可(ke)(ke)達225~325號。煤(mei)渣作(zuo)為水泥(ni)(ni)混(hun)(hun)合材(cai)料(liao)(liao),一般摻量控(kong)制在(zai)。
生石灰可以做干燥劑,理由是什么? - 已回答 :您好,生石灰能用在干燥劑的原理是由于生石灰吸水后能變成熟石灰,化學反應式是
CaO+H2O=Ca(OH)2,不過這里有一個放熱的過程,有一定的危險性,所以物流干燥劑一般會定義生石灰干燥劑做為危險品處理,目前,生石灰用做干燥劑也越來越少了,不過由于價格便宜成本低所以還有一定的使用空間。

食品中的石灰干燥劑除了防潮還可以用來干什么? - 已解決 :1.買(mai)了(le)包海苔,里面有一(yi)大包石灰(hui)干燥劑,能(neng)放入冰(bing)箱么(me)?
2.冰箱的除臭功能不好,自帶的那個除臭劑的成份(fen)是什(shen)么(me)?
不(bu)可以,,他的主要作用是防(fang)潮(chao),,冰箱(xiang)濕氣(qi)重。放了不(bu)用濕透了,濕透的防(fang)潮(chao)干燥(zao)劑(ji)也失去(qu)作用了。
因(yin)為對(dui)這方面知識熟悉(xi)的有限,所以在網(wang)上找了點資料,希望對(dui)你有用:
主要(yao)成分(fen)是炭類的 另外推薦(jian)幾個(ge)方便使(shi)用(yong)的方法給你: ) 橘(ju)子(zi)皮除味∶將(jiang)新鮮橘(ju)子(zi)500克(ke),吃完橘(ju)子(zi)后(hou),把橘(ju)子(zi)皮洗凈揩干,分(fen)散放(fang)入(ru)冰(bing)(bing)箱(xiang)(xiang)內。 3日(ri)后(hou)打(da)開冰(bing)(bing)箱(xiang)(xiang),清香(xiang)撲(pu)鼻(bi),異味全(quan)無。 2) 檸檬除味∶將(jiang)檸檬切成小片,放(fang)置在冰(bing)(bing)箱(xiang)(xiang)的各(ge)層,可除去(qu)異味。 3) 茶(cha)(cha)葉除味∶把50克(ke)花(hua)茶(cha)(cha)裝在紗布袋中,放(fang)入(ru)冰(bing)(bing)箱(xiang)(xiang),可除去(qu)異味。一(yi)個(ge)月(yue)后(hou),將(jiang)茶(cha)(cha)葉取出(chu)放(fang)在陽(yang)光(guang)下暴曬,可反復使(shi)用(yong)多(duo)次,效果很。
