Ukuza kuthi ga ngoku, akukho ngxelo malunga nomphumo wokongezwa kwendlela ye-hydroxyethyl cellulose kwinkqubo yepeyinti ye-latex. Ngophando, kufunyenwe ukuba ukongezwa kwe-hydroxyethyl cellulose kwinkqubo yepeyinti ye-latex ihluke, kwaye ukusebenza kwepeyinti ye-latex elungiselelwe ihluke kakhulu. Kwimeko yokongezwa okufanayo, indlela yokongeza iyahluka, kwaye i-viscosity yepeyinti ye-latex elungiselelwe iyahluka. Ukongeza, indlela yokongeza ye-hydroxyethyl cellulose nayo inempembelelo ecacileyo kakhulu ekugcinweni kozinzo lwepeyinti ye-latex.
Indlela yokongeza i-hydroxyethyl cellulose kwipeyinti ye-latex imisela isimo sayo sokusasazeka kwipeyinti, kwaye imeko yokusabalalisa yenye yezitshixo kwisiphumo sayo sokuqina. Ngophando, kufumaniseke ukuba i-cellulose ye-hydroxyethyl eyongeziweyo kwinqanaba lokusasazwa icwangciswe ngendlela ecwangcisiweyo phantsi kwesenzo sokucheba okuphezulu, kwaye kulula ukutyibilika omnye komnye, kunye nesakhiwo sothungelwano sothungelwano esithe kratya kunye nesiphithiphithi siyatshatyalaliswa, ngaloo ndlela. ukunciphisa ukusebenza kakuhle kokuqina. I-HEC yokuncamathelisa idityaniswe kwinqanaba le-let-down inomonakalo omncinci kakhulu kwisakhiwo sothungelwano lwesithuba ngexesha lenkqubo yokuvuselela isantya esiphantsi, kwaye umphumo wayo wokuqina ubonakaliswa ngokupheleleyo, kwaye esi sakhiwo sothungelwano siluncedo kakhulu ekuqinisekiseni ukuzinza kokugcina ipeyinti yelatex. Isishwankathelo, ukongezwa kwe-hydroxyethyl cellulose HEC kwinqanaba lokuyeka lepeyinti ye-latex kulungeleka ngakumbi ekusebenzeni kwayo okuphezulu kokuqina kunye nokuzinza okuphezulu kokugcinwa.
I-Cellulosic thickeners ibisoloko iyenye yezongezo zerheological ezibaluleke kakhulu kwiipeyinti ze-latex, phakathi kwayo i-hydroxyethyl cellulose (HEC) isetyenziswa kakhulu. Ngokutsho kweengxelo ezininzi zoncwadi, i-cellulose thickeners ineenzuzo ezilandelayo: ukusebenza kakuhle kokuqina, ukuhambelana kakuhle, ukuzinza okuphezulu kokugcinwa, ukuxhathisa kwe-sag, kunye nokunye okunjalo. Indlela yokongeza ye-hydroxyethyl cellulose ekuvelisweni kwepeyinti ye-latex iyaguquguquka, kwaye iindlela zokongeza eziqhelekileyo zezi zilandelayo:
01. Yongeza ngexesha le-pulping ukwandisa i-viscosity ye-slurry, ngaloo ndlela inceda ukuphucula ukusebenza kakuhle kokusabalalisa;
02. Lungisa i-viscous paste kwaye uyongeze xa udibanisa ipeyinti ukufezekisa injongo yokuqina.
