西藏常年供應高活性鈣基粉狀脫硫劑-現貨供應 <西藏>豫北鈣業有限公司

西藏工業級氫氧化(hua)鈣(gai)主要用(yong)途：用(yong)于(yu)(yu)建筑(zhu)物，用(yong)于(yu)(yu)制作單(dan)膠質，液體基礎，漂白(bai)劑(ji)和(he)石(shi)膏。該實驗(yan)室用(yong)于(yu)(yu)干(gan)燥和(he)醇脫水(shui)的(de)氨氣(qi)。通過與水(shui)反(fan)應，氧化(hua)鈣(gai)也可以(yi)(yi)產生大量的(de)熱量，通常(chang)用(yong)于(yu)(yu)自動加熱包裝。 堿性可以(yi)(yi)使脂(zhi)肪乳化(hua)，吸(xi)收水(shui)分(fen)，溶解蛋白(bai)質，和(he)腐蝕組織(zhi)。吸(xi)入(ru)石(shi)灰(hui)粉塵可能(neng)導(dao)致肺炎。高空濃(nong)度為5mg / m3。在工作時，應注(zhu)意保護(hu)呼吸(xi)器官(guan)，穿(chuan)防(fang)塵纖維(wei)，手(shou)套，密封防(fang)塵眼鏡，含有油的(de)軟膏以(yi)(yi)防(fang)止(zhi)灰(hui)塵吸(xi)入(ru)。生石(shi)灰(hui)是(shi)種(zhong)食品干(gan)燥劑(ji)，吸(xi)收空氣(qi)中(zhong)的(de)水(shui)分(fen)延長食物等，以(yi)(yi)及(ji)我們在某(mou)些物品中(zhong)看(kan)到的(de)白(bai)色粉末是(shi)一種(zhong)原(yuan)石(shi)。在辨別時，添加水(shui)不(bu)防(fang)止(zhi)高溫。只(zhi)需加入(ru)少量水(shui)以(yi)(yi)與粗石(shi)灰(hui)反(fan)應。氫氧化(hua)鈣(gai)灰(hui)塵或(huo)懸浮液滴加入(ru)水(shui)以(yi)(yi)表示石(shi)灰(hui)部分(fen)劣化(hua)。粘(zhan)膜的(de)作用(yong)可能(neng)導(dao)致打噴嚏和(he)咳嗽它是(shi)一種(zhong)沒有反(fan)應的(de)熟石(shi)灰(hui)。

工(gong)業級(ji)氫(qing)氧化鈣(gai)(gai)使用(yong)(yong)(yong)(yong)時(shi)(shi)(shi)(shi)的(de)注意事項 工(gong)業級(ji)氫(qing)氧化鈣(gai)(gai)長時(shi)(shi)(shi)(shi)間在(zai)(zai)空氣中(zhong)會吸收(shou)二氧化碳變成(cheng)(cheng)粉末狀(zhuang)碳酸鈣(gai)(gai)，起不(bu)到清塘消的(de)作用(yong)(yong)(yong)(yong)。因此生(sheng)(sheng)(sheng)(sheng)石(shi)灰(hui)(hui)好現買(mai)現用(yong)(yong)(yong)(yong)，且選擇塊狀(zhuang)較輕，不(bu)含(han)雜質的(de)為(wei)(wei)好。若(ruo)次用(yong)(yong)(yong)(yong)不(bu)完剩下的(de)生(sheng)(sheng)(sheng)(sheng)石(shi)灰(hui)(hui)用(yong)(yong)(yong)(yong)塑料袋扎(zha)口(kou)密封保存。 工(gong)業級(ji)氫(qing)氧化鈣(gai)(gai)要加入漿后(hou)趁熱潑(po)灑，忌將殘渣(zha)倒入池中(zhong)，以(yi)免池魚誤(wu)食而，更不(bu)可(ke)將整塊石(shi)灰(hui)(hui)扔(reng)到池中(zhong)進行水(shui)體消。 工(gong)業級(ji)氫(qing)氧化鈣(gai)(gai)忌與(yu)。 氮(dan)肥同(tong)時(shi)(shi)(shi)(shi)施(shi)用(yong)(yong)(yong)(yong)。生(sheng)(sheng)(sheng)(sheng)石(shi)灰(hui)(hui)遇(yu)水(shui)生(sheng)(sheng)(sheng)(sheng)成(cheng)(cheng)大(da)量的(de)OH-，氨(an)水(shui)含(han)量高(gao)易(yi)引起魚類(lei)氨(an)中(zhong)。同(tong)理，池水(shui)中(zhong)氨(an)氮(dan)含(han)量高(gao)于(yu)1.2毫(hao)克/升時(shi)(shi)(shi)(shi)，也不(bu)宜放用(yong)(yong)(yong)(yong)生(sheng)(sheng)(sheng)(sheng)石(shi)灰(hui)(hui)。另外施(shi)銨(an)態氮(dan)肥后(hou)隔(ge)周后(hou)方可(ke)使用(yong)(yong)(yong)(yong)生(sheng)(sheng)(sheng)(sheng)石(shi)灰(hui)(hui)，切忌混用(yong)(yong)(yong)(yong)。 工(gong)業級(ji)氫(qing)氧化鈣(gai)(gai)不(bu)能和磷(lin)肥混用(yong)(yong)(yong)(yong)。施(shi)磷(lin)肥后(hou)無機(ji)磷(lin)在(zai)(zai)pH為(wei)(wei)6.5～7.5時(shi)(shi)(shi)(shi)主要以(yi)化。 合物形式(shi)存在(zai)(zai)，若(ruo)與(yu)生(sheng)(sheng)(sheng)(sheng)石(shi)灰(hui)(hui)混用(yong)(yong)(yong)(yong)在(zai)(zai)pH大(da)于(yu)7.5時(shi)(shi)(shi)(shi)，會發生(sheng)(sheng)(sheng)(sheng)反應生(sheng)(sheng)(sheng)(sheng)成(cheng)(cheng)Ca（PO使有磷(lin)易(yi)形成(cheng)(cheng)鈣(gai)(gai)鹽沉淀而損(sun)失。般施(shi)生(sheng)(sheng)(sheng)(sheng)石(shi)灰(hui)(hui)后(hou)至少隔(ge)10～15天方可(ke)施(shi)磷(lin)肥。 工(gong)業級(ji)氫(qing)氧化鈣(gai)(gai)不(bu)能和漂(piao)，強氯精(jing)等(deng)鹵素(su)類(lei)混用(yong)(yong)(yong)(yong)。因為(wei)(wei)漂(piao)等(deng)為(wei)(wei)酸性，生(sheng)(sheng)(sheng)(sheng)石(shi)灰(hui)(hui)為(wei)(wei)堿(jian)性，若(ruo)混用(yong)(yong)(yong)(yong)。
