Ukusetshenziswa kwe-hydroxyethyl cellulose (HEC) ekugqokeni kunezinzuzo eziningi, ukumboza izakhiwo zomzimba, amasu okucubungula kanye nemiphumela yesicelo.
1. Ukuqina komphumela
I-Hydroxyethyl cellulose iyi-thickener ephumelelayo engakhuphula kakhulu i-viscosity yezingubo. Umthelela wayo wokuqina ungafinyelela imiphumela ebalulekile emazingeni aphansi okungeza, ngaleyo ndlela kuthuthukiswe ukusebenza kwesicelo sokumboza. I-viscosity kapende iphakathi, engagwema izinkinga ezifana nokuwohloka nokuwohloka ngesikhathi sokudweba, futhi kuthuthukise ukufana kokwakhiwa kanye nokucaba kwefilimu yokumboza.
2. Ukuzinza okuthuthukisiwe
I-HEC inomphumela omuhle wokuzinzisa kuma-coatings. Ingakwazi ukuzinzisa ukusakazeka kombala kanye nezigcwalisi ngokuxhumanisa ngokomzimba kanye nokusebenzisana kwamakhemikhali, ivimbele ukuhlaliswa kanye nokukhishwa kwemibala nokugcwalisa ngesikhathi sokugcina noma ukusetshenziswa. Lokhu akugcini nje ukwandisa impilo yeshalofu kapende kodwa futhi kuqinisekisa nokusatshalaliswa kwezingulube ngesikhathi sokufaka isicelo.
3. Thuthukisa i-rheology
I-Hydroxyethyl cellulose inomthelela omkhulu ku-rheology ye-coating, okwenza ukuthi ukunamathela kubonise izakhiwo ze-pseudoplastic (shear thinning). Ngamazinga aphansi e-shear, upende ugcina i-viscosity ephezulu, ekulungele ukuma nokugcinwa; ngenkathi amazinga aphezulu e-shear (njengalapho uxubha futhi ufafaza), i-viscosity yepende iyancipha, okwenza kube lula ukugeleza nokusebenzisa. Lesi sici sokunciphisa i-shear senza ukunamathela kube lula ukusisebenzisa ngesikhathi sokusetshenziswa, futhi ifilimu yokugqoka ibushelelezi futhi ilingana.
4. Thuthukisa ukumelana ne-sag
Uma usebenzisa upende ezindaweni eziqondile, i-HEC ingathuthukisa kakhulu ukumelana nopende ukuze ungagxumeki. Lokhu kungenxa yomphumela wayo wokuqina kanye nezakhiwo ze-rheological ezivumela upende ukuthi wenze ngokushesha isakhiwo esifana nejeli ngemva kokufaka isicelo, sinciphise ukuthambekela kokugeleza, ngaleyo ndlela kuvimbele upende ukuthi ungagugi futhi ugoqe.
5. Thuthukisa izindawo zokuthambisa
I-HEC igcina ngempumelelo umswakama, ngaleyo ndlela yandisa isikhathi sokumisa upende. Lokhu kubaluleke kakhulu kwezinye izigqoko ezidinga isikhathi eside sokusebenza, njengopende wezinkuni, upende wobuciko, njll. Isikhathi esinwetshiwe sokumisa sinikeza umakhi isikhathi esiningi sokusebenza futhi sigwema izimpawu zokudweba kanye nobunzima bokwakha obubangelwa ukomiswa ngokweqile kopende.
6. Thuthukisa ukusebenza kokuxubha
Njengoba i-HEC ithuthukisa izakhiwo ze-rheological kanye nomphumela wokujiya wopende, upende ubonisa izinga elingcono lapho uxutshwa. Lapho uxubha, upende lungasakazwa ngokulinganayo ngaphandle kwezimpawu zokuxubha, futhi ifilimu yokugcina yokugqoka ibushelelezi futhi ithambile. Lokhu kubaluleke kakhulu ekugqokeni okuphezulu kwekhwalithi ephezulu, njengezingubo zefenisha, izigqoko zezimoto, njll.
7. Kuyavumelana nezimo
I-HEC inokuqina okuhle kwamakhemikhali nokuhambisana futhi ihambisana nezinhlelo ezihlukahlukene zokumboza, njengezingubo ezisekelwe emanzini, opende be-latex, opende abasekelwe uwoyela, njll. Ikwazi ukuguquguquka okubanzi kumafomula ahlukene kanye nezithako, ngeke isabele kabi nezinye. izithako, futhi ngeke kubangele kalula izinguquko zamakhemikhali kufomula.
8. Thuthukisa ukusebenza kwe-coating
I-HEC ayihlinzeki nje kuphela ngemiphumela yokuqina nokuqiniswa kwezingubo zokugqoka, kodwa futhi ithuthukisa izakhiwo ezibonakalayo zefilimu yokugqoka. Isibonelo, ingathuthukisa ukumelana nokuqhekeka, ukumelana nokukhuhla kanye nokuguquguquka kwefilimu yokugqoka. Lokhu kwenza i-coating yokugcina ihlale isikhathi eside, ikwazi ukugcina ubuhle bayo nokusebenza ngaphansi kwezimo ezihlukahlukene zemvelo.
9. Ukuvikelwa kwemvelo
I-HEC iyimpahla ebolayo enezinto ezinhle zokuvikela imvelo. Uma iqhathaniswa namanye ama-thickeners okwenziwa, inomthwalo omncane wemvelo futhi ayikhiphi izinto eziyingozi ngesikhathi sokusetshenziswa. Lokhu kuhambisana nezidingo eziphakeme zokuvikela imvelo embonini yesimanje yokumboza futhi kuvumelana nesidingo sabathengi semikhiqizo eluhlaza.
10. Kulula ukuphatha nokuhlakaza
I-HEC incibilika kalula futhi ihlakazeke emanzini futhi yakhe uketshezi olufana ne-viscous. Enqubweni yokukhiqiza enamathelayo, ukuhlakazeka nokuhlakazeka kwayo kwenza inqubo yokukhiqiza ibe lula futhi ingathambekeli kakhulu ezinkingeni ze-agglomeration noma ukuhlakazeka okungaphelele, kunciphisa izinkinga enqubweni yokukhiqiza kanye nokwenza ngcono ukusebenza kahle kokukhiqiza.
Ukusetshenziswa kwe-hydroxyethyl cellulose embotsheni kunezinzuzo eziningi. Akukona nje ukuthuthukisa izakhiwo ezibonakalayo nokusebenza kokwakhiwa kokugqoka, kodwa futhi kuthuthukisa ukuzinza kanye nezici zokuvikela imvelo zokugqoka. Idlala indima ebalulekile ekwakhiweni kopende lwesimanje, ihlinzeka ngezixazululo ezisebenzayo zokufeza imiphumela yokudweba yekhwalithi ephezulu. Ngokuthuthukiswa kobuchwepheshe bokumboza kanye nokwehlukahlukana kwesidingo semakethe, amathemba okufaka isicelo e-HEC enamathela azoba banzi.
