Ngenxa yezakhiwo zawo zamakhemikhali eziyingqayizivele, ama-cellulose ethers ayizithako eziyinhloko ekukhiqizeni upende we-latex.Asetshenziswa kumapende e-latex njengama-thickeners, ama-rheology modifiers, ama-colloid avikelayo kanye nama-ejenti okugcina amanzi.Ama-cellulose ether adlala indima ebalulekile ekwakhiweni nasekusetshenzisweni kopende be-latex, futhi ukusetshenziswa kwawo sekuyinto evamile embonini yokumboza.
Ama-Thickeners kanye ne-Rheology Modifiers:
Omunye wemisebenzi eyisisekelo yama-cellulose ethers njengama-thickeners nama-rheology modifiers.I-Rheology iwucwaningo lokuwohloka nokugeleza kwento, futhi idlala indima ebalulekile ekusetshenzisweni kwezimbotshana.Izilungisi ze-Rheology zengezwa ekwakhiweni kopende ukuze kulawulwe izici zokugeleza kopende futhi kuqinisekiswe ukuthungwa okungaguquki nokumbozwa.Ngokusebenza njengama-thickeners nama-rheology modifiers, ama-cellulose ethers angajiya upende we-latex futhi enze kube lula ukuwufaka.
Ama-cellulose ether ama-polymers ancibilika emanzini afana namakhemikhali afana ne-cellulose, i-polymer eyenzeka ngokwemvelo etholakala ezitshalweni.Izakhiwo zamakhemikhali eziyingqayizivele zama-cellulose ethers ziwavumela ukuba ajiye upende we-latex ngaphandle kokuthinta kakhulu i-viscosity yawo, ukuqinisekisa ukuthi upende unobushelelezi, ngisho nokuthungwa.
Ngenxa yezakhiwo zabo eziqina, ama-cellulose ethers nawo athuthukisa izakhiwo zokunamathisela zezingubo.Ngokwandisa ubukhulu befilimu kapende, kusiza ukuthuthukisa isibopho phakathi kopende nongaphezulu, ukuqinisekisa ukuthi upende uhlala isikhathi eside.
I-protective colloid:
Ama-cellulose ether angama-colloid avikelayo asebenzayo asiza ukuzinzisa izinhlayiya ze-colloidal kumapende we-latex.Ama-Colloids ayizinhlayiya ezincane ezihlakazekile endaweni ephakathi, kulokhu, upende.Ukuzinza kwalezi zinhlayiya kubalulekile ekugcineni ubuqotho obuphelele bokubunjwa kokugqoka.
Ukwengeza i-cellulose ethers ekubunjweni kokugqoka kuqinisekisa ukuthi izinhlayiya ze-colloidal zihlala zihlakazekile ngokulinganayo ekuhlanganiseni, ukuvimbela ukwakheka kwama-clumps.Ukwengeza, izici ezivikelayo ze-colloid ze-cellulose ether zivimbela upende we-latex ekubeni ugqinsile kakhulu noma uqine ngokuhamba kwesikhathi.Lokhu kuqinisekisa ukuthi upende kulula ukuwufaka futhi uhlala uzinzile futhi ungaguquguquki kukho konke ukusetshenziswa.
Ukugcinwa kwamanzi:
Enye impahla ebalulekile yama-cellulose ether amandla awo okubamba amanzi.Ekwenziweni kopende, amanzi avame ukungezwa njenge-diluent ukuze enze ukubushelelezi, ngisho nokuthungwa futhi kuthuthukiswe izakhiwo zokusetshenziswa kopende.Kodwa-ke, amanzi angabangela futhi upende ukuba wome ngokushesha, okubangela ukuba isibopho phakathi kopende nobuso bube buthaka.
Ngokugcina umswakama, ama-cellulose ethers aqinisekisa ukuthi ukugqoka kuhlala kumanzi kuyo yonke inqubo yokufaka isicelo, kuvimbele ukuthi ukoma ngokushesha okukhulu.Lokhu kuvumela upende ukuthi lome ngokulinganayo futhi wenze isibopho esiqinile, esihlala isikhathi eside nendawo.
Ekuphetheni:
Ama-cellulose ethers ayingxenye ebalulekile yamapende e-latex ngenxa yezakhiwo zawo zamakhemikhali eziyingqayizivele.Zisetshenziswa ekubunjweni kokugqoka njengama-thickeners, ama-rheology modifiers, ama-colloid avikelayo kanye nama-agent okugcina amanzi.Ngokuhlinzeka ngale misebenzi eminingi, ama-cellulose ethers aqinisekisa ukuthi amapende e-latex ahlala ezinzile, angaguquki futhi kulula ukuwasebenzisa.Ukusetshenziswa kwabo kuye kwashintsha imboni yezingubo zokugqoka, futhi izinzuzo zabo ziqashelwa kabanzi abakhiqizi nabasebenzisi.
