Waa lagama maarmaan in lagu daro cellulose alaabta gypsum-ku salaysan

Sababo la xiriira sida heerkulka hawada, qoyaanka, cadaadiska dabaysha, iyo xawaaraha dabaysha, heerka isbedbedelka qoyaanka ee alaabta gypsum-ku-saleysan ayaa saameyn doonta.

Markaa haddii ay ku jirto hoobiye-ku-salaysan gypsum-ku-salaysan, caulk, putty, ama is-heeraynta gypsum-ku-salaysan, hydroxypropyl methylcellulose ether (HPMC) ayaa door muhiim ah ka ciyaara.

Haysashada biyaha BAOSHUIXINGHPMC

Heerarka sare ee hydroxypropyl methylcellulose (HPMC) ayaa si wax ku ool ah u xalin kara dhibaatada haynta biyaha ee heerkulka sare.

Methoxy iyo kooxaha hydroxypropoxy waxay si siman u qaybsan yihiin silsiladda molecular cellulose, taas oo wanaajin karta awoodda atamka oksijiinta ee hydroxyl iyo ether bonds si ay ula xiriiraan biyaha si ay u sameeyaan bonds hydrogen, samaynta biyo bilaash ah biyo xidhxidhan, si wax ku ool ah u xakameeyo uumiga. biyaha ay sababto heerkulka sare ee cimilada si loo gaaro haynta biyaha sare.

Dhismaha SHIGONGXINGHPMC

Alaabooyinka ether cellulose ee si sax ah loo doortay waxay si dhakhso ah ugu dhex geli karaan alaabada gypsum kala duwan iyada oo aan la kicin, wax saameyn ah kuma yeelanayaan porosity ee alaabta gypsum ee la daaweeyay, taas oo hubinaysa waxqabadka neefsashada ee alaabta gypsum.

Waxay leedahay saameyn dib-u-dhac gaar ah laakiin ma saameynayso koritaanka kiristaalo gypsum;waxay hubisaa awoodda isku-xidhka ee walxaha dusha sare leh oo leh qoyan qoyan oo ku habboon, waxay si weyn u wanaajisaa waxqabadka dhismaha ee alaabta gypsum, waana sahlan tahay in la faafiyo iyada oo aan qalab lagu dhejin.

Dufanka RUNHUAXINGHPMC

Hydroxypropyl methylcellulose tayo sare leh ayaa si siman oo waxtar leh loogu kala firdhi karaa hoobiye sibidhka iyo alaabta gypsum-ku salaysan, oo ku duub dhammaan qaybaha adag, oo samee filim qoynta, qoyaanka saldhigga ayaa si tartiib tartiib ah u milmi doona wakhti dheer.sii daayo, oo la marsiiyo falcelinta fuuq-celinta alaabada gelling-ka aan organic-ga ahayn, si loo hubiyo awoodda isku-xidhka iyo xoogga isku-buufinta ee walxaha.
