Parizvino, hapana mushumo pamusoro pemhedzisiro yekuwedzera nzira yehydroxyethyl cellulose pane latex pendi system. Kuburikidza nekutsvakurudza, kunowanikwa kuti kuwedzerwa kwehydroxyethyl cellulose mu latex pendi system yakasiyana, uye kushanda kwependi yakagadzirwa nelatex yakasiyana zvikuru. Muchiitiko chekuwedzera kumwe chete, nzira yekuwedzera yakasiyana, uye viscosity yepende yakagadzirirwa latex yakasiyana. Pamusoro pezvo, iyo nzira yekuwedzera yehydroxyethyl cellulose zvakare ine mhedzisiro yakajeka pakuchengetedza kugadzikana kwepende yelatex.
Nzira yekuwedzera hydroxyethyl cellulose mu latex pendi inosarudza kupararira kwayo mupende, uye mamiriro ekupararira ndeimwe yemakiyi ekukora kwayo. Kuburikidza netsvagiridzo, zvinoonekwa kuti hydroxyethyl cellulose yakawedzerwa muchikamu chekuparadzira inorongwa nenzira yakarongeka pasi pekuita kweshear yakakwirira, uye zviri nyore kutsvedza mumwe nemumwe, uye iyo inopindirana uye yakabatana nzvimbo yetiweki chimiro inoparadzwa, nekudaro. kuderedza thickening kunyatsoshanda. Iyo paste HEC yakawedzerwa padanho rekudzikisa-pasi ine kukuvadza kudiki kune nzvimbo yetiweki dhizaini panguva yakaderera-yekumhanyisa maitiro, uye iyo thickening mhedzisiro inoratidzwa zvizere, uye iyi network chimiro zvakare inobatsira kwazvo kuve nechokwadi chekuchengetedza kugadzikana. iyo latex pendi. Muchidimbu, kuwedzerwa kwehydroxyethyl cellulose HEC muchikamu chekudzikisa chepende yelatex inonyanya kuita kuti iwedzere kusimba uye kugadzikana kwekuchengetedza kwakanyanya.
Celulosic thickeners yagara iri imwe yeakakosha rheological additives ye latex pendi, pakati peiyo hydroxyethyl cellulose (HEC) ndiyo inonyanya kushandiswa. Zvinoenderana nemashumo mazhinji ezvinyorwa, cellulose thickeners ane zvinotevera zvakanakira: yakakwirira thickening kunyatsoshanda, kuenderana kwakanaka, yakakwirira yekuchengetedza kugadzikana, yakanakisa sag kuramba, nezvimwe zvakadaro. Iyo yekuwedzera nzira yehydroxyethyl cellulose mukugadzirwa kwependi yelatex inoshanduka, uye nzira dzakajairika dzekuwedzera ndedzinotevera:
01. Wedzera iyo panguva yekuputika kuti uwedzere viscosity ye slurry, nokudaro kubatsira kuvandudza kupararira kwekushanda;
02. Gadzirira paste yakasvibirira uye uiwedzere paunenge uchisanganisa pende kuti uwane chinangwa chekuwedzera.
