水(shui)性脫(tuo)模(mo)劑,也(ye)叫水(shui)質脫(tuo)模(mo)劑,是由有機高(gao)分子材(cai)料(liao)研制(zhi)成(cheng)的,易溶于水(shui),兌水(shui)后(hou)(hou),直(zhi)接(jie)(jie)(jie)涂刷于模(mo)板(ban)后(hou)(hou)形成(cheng)一層很(hen)滑的隔(ge)離膜,該膜能(neng)完全阻止(zhi)混(hun)(hun)凝(ning)土與(yu)模(mo)板(ban)的直(zhi)接(jie)(jie)(jie)接(jie)(jie)(jie)觸(chu)并(bing)且有助于在澆注混(hun)(hun)凝(ning)土時,混(hun)(hun)凝(ning)土與(yu)模(mo)板(ban)接(jie)(jie)(jie)觸(chu)處(chu)的氣泡能(neng)迅速溢(yi)出,使(shi)梁柱不(bu)會出現氣孔,美觀。使(shi)用之后(hou)(hou)不(bu)影(ying)響混(hun)(hun)凝(ning)土的強度,對鋼筋無(wu)(wu)腐蝕作用。無(wu)(wu)毒,無(wu)(wu)害,綠色(se)產品。
油(you)(you)(you)性(xing)脫模劑(ji)(ji)是精(jing)選進(jin)口材料(liao)調制(zhi)而(er)成的注塑(su)機成型專用(yong)脫模劑(ji)(ji),不(bu)(bu)含CFA,環(huan)保無(wu)毒。油(you)(you)(you)性(xing)脫模劑(ji)(ji)對產(chan)品及(ji)模具(ju)不(bu)(bu)腐蝕(shi),不(bu)(bu)影響(xiang)產(chan)品的第二次加工(gong),表(biao)(biao)面不(bu)(bu)油(you)(you)(you)膩。特別適(shi)用(yong)用(yong)于大型塑(su)膠外殼產(chan)品成型。傳(chuan)統的機油(you)(you)(you),稱油(you)(you)(you)性(xing)脫模劑(ji)(ji),其粘性(xing)及(ji)稠度高,氣泡不(bu)(bu)容(rong)易(yi)溢出造成拆(chai)模后表(biao)(biao)面出現氣孔,并(bing)且嚴重影響(xiang)后續(xu)表(biao)(biao)面抹(mo)灰砂漿與混凝土基層的粘結力,影響(xiang)工(gong)程(cheng)質量。
水(shui)(shui)(shui)性(xing)(xing)(xing)(xing)脫(tuo)模(mo)劑和油(you)性(xing)(xing)(xing)(xing)脫(tuo)模(mo)劑最主要(yao)(yao)(yao)的區別原材(cai)料(liao)肯定不(bu)一(yi)樣,使用(yong)(yong)(yong)方法(fa)也不(bu)一(yi)樣。水(shui)(shui)(shui)性(xing)(xing)(xing)(xing)脫(tuo)模(mo)劑使用(yong)(yong)(yong)時與水(shui)(shui)(shui)按一(yi)定比例調(diao)兌后,再噴涂。水(shui)(shui)(shui)性(xing)(xing)(xing)(xing)脫(tuo)模(mo)劑使用(yong)(yong)(yong)簡單安全、最主要(yao)(yao)(yao)環保。油(you)性(xing)(xing)(xing)(xing)脫(tuo)模(mo)劑需(xu)要(yao)(yao)(yao)跟二氯甲烷(wan)、石(shi)油(you)醚120#汽(qi)油(you)等(deng)溶劑調(diao)兌后使用(yong)(yong)(yong),它(ta)相對(dui)水(shui)(shui)(shui)性(xing)(xing)(xing)(xing)脫(tuo)模(mo)劑成(cheng)本較高、存在(zai)安全隱患、且不(bu)環保。水(shui)(shui)(shui)性(xing)(xing)(xing)(xing)脫(tuo)模(mo)劑對(dui)模(mo)具的溫(wen)度(du)有較高的要(yao)(yao)(yao)求,需(xu)要(yao)(yao)(yao)讓(rang)里面的水(shui)(shui)(shui)分(fen)快速蒸發掉,但是用(yong)(yong)(yong)水(shui)(shui)(shui)性(xing)(xing)(xing)(xing)脫(tuo)模(mo)劑操(cao)作環境(jing)比較好,氣味低(di),污染小。油(you)性(xing)(xing)(xing)(xing)脫(tuo)模(mo)劑揮發快,不(bu)用(yong)(yong)(yong)升高模(mo)具溫(wen)度(du)使其蒸發。但是殘留(liu)物比較多,相對(dui)不(bu)容易清洗,氣味比較大。
