Okwangoku, akukho ngxelo ikhoyo malunga nefuthe lendlela yokongeza i-hydroxyethyl cellulose kwinkqubo yokupenda i-latex. Ngophando, kufunyaniswe ukuba ukongezwa kwe-hydroxyethyl cellulose kwinkqubo yokupenda i-latex kwahlukile, kwaye ukusebenza kwepeyinti ye-latex elungisiweyo kwahlukile kakhulu. Kwimeko yokongeza okufanayo, indlela yokongeza yahlukile, kwaye i-viscosity yepeyinti ye-latex elungisiweyo yahlukile. Ukongeza, indlela yokongeza i-hydroxyethyl cellulose ikwanempembelelo ecacileyo ekuzinzeni kokugcinwa kwepeyinti ye-latex.
Indlela yokufaka i-hydroxyethyl cellulose kwipeyinti yelatex imisela imeko yayo yokusasazeka kwipeyinti, kwaye imeko yokusasazeka yenye yezona zinto zibalulekileyo kwisiphumo sayo sokutyeba. Ngophando, kufunyaniswe ukuba i-hydroxyethyl cellulose eyongeziweyo kwisigaba sokusasazeka icwangciswe ngendlela ehlelekileyo phantsi kwesenzo sokucheba okuphezulu, kwaye kulula ukutyibilika, kwaye isakhiwo senethiwekhi yendawo esidibeneyo nesidibeneyo siyatshatyalaliswa, ngaloo ndlela kunciphisa ukusebenza kakuhle kokutyeba. I-paste HEC eyongeziweyo kwisigaba sokuthotywa inomonakalo omncinci kakhulu kwisakhiwo senethiwekhi yendawo ngexesha lenkqubo yokuxubha ngesantya esiphantsi, kwaye isiphumo sayo sokutyeba sibonakaliswa ngokupheleleyo, kwaye olu lwakhiwo lwenethiwekhi lukwaluncedo kakhulu ukuqinisekisa uzinzo lokugcina lwepeyinti yelatex. Ngamafutshane, ukongezwa kwe-hydroxyethyl cellulose HEC kwisigaba sokuthotywa kwepeyinti yelatex kunceda ngakumbi ekusebenzeni kwayo okuphezulu kokutyeba kunye nokuzinza okuphezulu kokugcina.
Izithambisi ze-cellulosic bezisoloko zizezinye zezona zinto zibalulekileyo zokongeza i-rheological kwiipeyinti ze-latex, apho i-hydroxyethyl cellulose (HEC) iyeyona isetyenziswa kakhulu. Ngokweengxelo ezininzi zeencwadi, izithambisi ze-cellulose zinezibonelelo ezilandelayo: ukusebenza kakuhle kokuqina, ukuhambelana okuhle, ukuzinza okuphezulu kokugcina, ukumelana okuhle kokuwa, kunye nezinye izinto ezifana nezo. Indlela yokongeza i-hydroxyethyl cellulose kwimveliso yepeyinti ye-latex iyaguquguquka, kwaye iindlela zokongeza eziqhelekileyo zezi zilandelayo:
01. Yongeza ngexesha lokuxubha ukuze wonyuse uburhabaxa be-slurry, ngaloo ndlela uncede ukuphucula ukusebenza kakuhle kokusasazeka;
02. Lungisa intlama ethambileyo uze uyifake xa uxuba ipeyinti ukuze ufezekise injongo yokuyenza ibe nkulu.
