Kuze kube manje, awukho umbiko ngomphumela wendlela yokwengeza ye-hydroxyethyl cellulose ohlelweni lokupenda lwe-latex. Ngokucwaninga, kutholakala ukuthi ukungezwa kwe-hydroxyethyl cellulose ohlelweni lwepende ye-latex kuhlukile, futhi ukusebenza kopende olungiselelwe we-latex kuhluke kakhulu. Endabeni yokwengezwa okufanayo, indlela yokwengeza ihlukile, futhi i-viscosity yopende olungiselelwe we-latex ihlukile. Ngaphezu kwalokho, indlela yokwengeza ye-hydroxyethyl cellulose nayo inomthelela osobala kakhulu ekuzinzeni kwesitoreji sopende we-latex.
Indlela yokwengeza i-hydroxyethyl cellulose kupende we-latex inquma isimo sayo sokuhlakazeka kupende, futhi isimo sokuhlakazeka singesinye sezihluthulelo zomphumela wawo wokujiya. Ngocwaningo, kutholakala ukuthi i-hydroxyethyl cellulose engezwe esigabeni sokuhlakazeka ihlelwe ngendlela ehlelekile ngaphansi kwesenzo se-shear ephezulu, futhi kulula ukushelelana, futhi isakhiwo senethiwekhi yendawo egqagqene futhi esihlangene siyabhujiswa, ngaleyo ndlela. ukunciphisa ukusebenza kahle kokuqina. I-HEC yokunamathisela efakwe esiteji sokwehlisa inomonakalo omncane kakhulu esakhiweni senethiwekhi yesikhala ngesikhathi senqubo yokugqugquzela isivinini esiphansi, futhi umphumela wayo wokuqina ubonakala ngokugcwele, futhi lesi sakhiwo senethiwekhi sizuzisa kakhulu ukuqinisekisa ukuzinza kwesitoreji. upende we-latex. Kafushane, ukungezwa kwe-hydroxyethyl cellulose HEC esigabeni sokwehlisa upende we-latex kusiza kakhulu ekusebenzeni kwayo okuphezulu kokuqina kanye nokuzinza okuphezulu kwesitoreji.
Ama-Cellulosic thickeners abelokhu engenye yezithako ze-rheological ezibaluleke kakhulu zopende be-latex, phakathi kwayo i-hydroxyethyl cellulose (HEC) esetshenziswa kakhulu. Ngokwemibiko eminingi yezincwadi, ama-cellulose thickeners anezinzuzo ezilandelayo: ukusebenza kahle kokuqina okuphezulu, ukuhambisana okuhle, ukuzinza okuphezulu kwesitoreji, ukumelana okuhle kakhulu kwe-sag, nokunye okunjalo. Indlela yokwengeza ye-hydroxyethyl cellulose ekukhiqizeni upende we-latex iyavumelana nezimo, futhi izindlela zokwengeza ezivame kakhulu yilezi ezilandelayo:
01. Yengeze ngesikhathi se-pulping ukwandisa i-viscosity ye-slurry, ngaleyo ndlela usize ukuthuthukisa ukusebenza kahle kokuhlakazeka;
02. Lungiselela i-viscous paste futhi uyengeze lapho uhlanganisa upende ukuze ufeze injongo yokuqina.
