I-Hydroxypropyl methylcellulose, eyaziwa ngokuba yi-HPMC, i-ether ye-cellulose e-nonionic efunyenwe kwi-cotton ecocekileyo, i-polymer material yendalo, ngokusebenzisa uchungechunge lweenkqubo zemichiza.Ngumgubo omhlophe okanye omthubi onyibilika lula emanzini.Makhe sithethe ngendlela yokuchithwa kwe-hydroxypropyl methylcellulose.
1. I-Hydroxypropyl methylcellulose isetyenziswa kakhulu njenge-additive for putty powder, mortar and glue.Ifakwe kwi-cement mortar, ingasetyenziselwa njenge-arhente yokugcina amanzi kunye ne-retardant ukwandisa ukumpompa;ifakwe kwi-putty powder kunye neglue, ingasetyenziselwa njenge-binder.Ukuze kuphuculwe ukusabalalisa kunye nokwandisa ixesha lokusebenza, sithatha i-Qingquan Cellulose njengomzekelo wokuchaza indlela yokuchithwa kwe-hydroxypropyl methylcellulose.
2. I-Hydroxypropyl methylcellulose eqhelekileyo iqala ukuxutywa kwaye ihlakazwe ngamanzi ashushu, emva koko ifakwe ngamanzi abandayo, ixutywe kwaye ipholile ukuze inyibilike;
Ngokukodwa: thatha i-1/5-1/3 yomthamo ofunekayo wamanzi ashushu, ugxobhoze de imveliso eyongeziweyo idumbe ngokupheleleyo, uze udibanise inxenye eseleyo yamanzi ashushu, anokuba ngamanzi abandayo okanye amanzi omkhenkce, kwaye ushukumise iqondo lobushushu elifanelekileyo (10°C ) de inyibilike ngokupheleleyo.
3. Indlela yokumanzisa isinyibilikisi se-organic:
Ukusasaza i-hydroxypropyl methylcellulose kwi-solvent ephilayo okanye uyinyakazise nge-solvent ye-organic, kwaye wongeze okanye wongeze amanzi abandayo ukuwanyibilikisa kakuhle.I-solvent ye-organic ingaba yi-ethanol, i-ethylene glycol, njl.
4. Ukuba i-agglomeration okanye ukusonga kwenzeka ngexesha lokuchithwa, kungenxa yokuba ukuvuselela akwanelanga okanye imodeli eqhelekileyo yongezwa ngokuthe ngqo kumanzi abandayo.Ngeli xesha, xuba ngokukhawuleza.
5. Ukuba ama-bubbles aveliswa ngexesha lokuchithwa, angashiywa kwiiyure ezingama-2-12 (ixesha elithile lixhomekeke ekungqineni kwesisombululo) okanye asuswe ngokucoca, ukuxinzelela, njl., okanye ukongeza inani elifanelekileyo le-agent defoaming.
Ukulumkela
IHydroxypropyl methylcellulose yahlulwe yaba ziindidi zokunyibilika kancinane kunye nezinyibilikayo ngoko nangoko.I-hydroxypropyl methylcellulose ekhawulezileyo inokunyibilika ngokuthe ngqo kumanzi abandayo.
