I-Cellulose ether iyi-polymer engeyona i-ionic semi-synthetic, encibilika emanzini futhi encibilika. Inemiphumela ehlukene ezimbonini ezahlukene. Isibonelo, ezintweni zokwakha zamakhemikhali, zinemiphumela elandelayo eyinhlanganisela:
①I-ejenti egcina amanzi, ②Thickener, ③Leveling impahla, ④Isakhiwo sefilimu, ⑤Binder
Embonini ye-polyvinyl chloride, iyi-emulsifier ne-dispersant; embonini yezemithi, iyisibophezelo kanye nezinto zohlaka lokukhishwa kancane futhi olulawulwayo, njll. Ngenxa yokuthi i-cellulose inemiphumela ehlukahlukene ehlanganisiwe, ukusetshenziswa kwayo Inkambu nayo ibanzi kakhulu. Okulandelayo, ngizogxila ekusetshenzisweni nasekusebenzeni kwe-cellulose ether ezintweni zokwakha ezihlukahlukene.
ngopende we-latex
Embonini yepende ye-latex, ukukhetha i-hydroxyethyl cellulose, ukucaciswa okujwayelekile kwe-viscosity elinganayo yi-30000-50000cps, ehambisana nokucaciswa kwe-HBR250, futhi isilinganiso sereferensi ngokuvamile simayelana ne-1.5 ‰ -2 ‰. Umsebenzi oyinhloko we-hydroxyethyl kupende we-latex ukujiya, ukuvimbela i-gelation ye-pigment, ukusiza ukuhlakazeka kwe-pigment, ukuqina kwe-latex, nokwandisa i-viscosity yezingxenye, okunomthelela ekusebenzeni kokulinganisa kokwakhiwa: I-Hydroxyethyl cellulose kulula ukuyisebenzisa. Ingancibilika emanzini abandayo nasemanzini ashisayo, futhi ayithinteki ngenani le-pH. Ingasetshenziswa ngokuphephile phakathi kwe-PI value 2 kanye ne-12. Izindlela zokusebenzisa zimi kanje:
I. Engeza ngokuqondile ekukhiqizeni
Ngale ndlela, kufanele kukhethwe uhlobo olubambezelekile lwe-hydroxyethyl cellulose, bese kusetshenziswa i-hydroxyethyl cellulose enesikhathi sokuhlakazeka esingaphezu kwemizuzu engama-30. Izinyathelo zimi kanje: ① Faka inani elithile lamanzi ahlanzekile esitsheni esifakelwe isishicileli esishear kakhulu ② Qala ukunyakazisa ngokuqhubekayo ngesivinini esiphansi, futhi ngesikhathi esifanayo ungeze kancane kancane iqembu le-hydroxyethyl esixazululweni ngokulinganayo ③Qhubeka ugoqoza kuze zonke izinto eziyimbudumbudu zicwilisiwe ④Engeza ezinye izithasiselo neziyisisekelo, njll. ⑤Guqula kuze Amaqembu e-hydroxyethyl ahlakazeka ngokuphelele, bese Engeza ezinye izingxenye kufomula bese ugaya kuze kube umkhiqizo ophelile.
2. Ifakwe utshwala bukamama ukuze busetshenziswe kamuva
Le ndlela ingakhetha uhlobo olusheshayo, futhi ine-anti-mildew effect cellulose. Inzuzo yale ndlela yukuthi inokuguquguquka okukhulu futhi ingafakwa ngokuqondile kupende we-latex. Indlela yokulungiselela iyafana nezinyathelo ①-④.
3. Kwenze kube iphalishi ukuze ulisebenzise kamuva
Njengoba izincibilikisi zemvelo zingama-solvents ampofu (angancibiliki) ku-hydroxyethyl, lezi zinyibilikisi zingasetshenziswa ukwenza iphalishi. Izincibilikisi eziphilayo ezisetshenziswa kakhulu uketshezi lwemvelo ekwenziweni kopende kwe-latex, okufana ne-ethylene glycol, i-propylene glycol, nama-ejenti akha ifilimu (njenge-diethylene glycol butyl acetate). Iphalishi i-hydroxyethyl cellulose ingafakwa ngokuqondile kupende. Qhubeka ugoqa kuze kuqedwe ngokuphelele.
ku-putty
Njengamanje, emadolobheni amaningi ezweni lami, i-putty engavimbeli amanzi kanye ne-scrub-friendly i-putty iye yaziswa kakhulu abantu. Ikhiqizwa ukusabela kwe-acetal ye-vinyl utshwala ne-formaldehyde. Ngakho-ke, le nto isuswa kancane kancane ngabantu, futhi imikhiqizo yochungechunge lwe-cellulose ether isetshenziselwa ukufaka esikhundleni salokhu. Okusho ukuthi, ukuthuthukiswa kwezinto zokwakha ezinobungani bemvelo, i-cellulose okwamanje yiyona nto kuphela.
Ku-putty engavimbeli amanzi, ihlukaniswe yaba izinhlobo ezimbili: i-powder putty ne-putty paste. Phakathi kwalezi zinhlobo ezimbili ze-putty, i-methyl cellulose ne-hydroxypropyl methyl kufanele kukhethwe. Ukucaciswa kwe-viscosity ngokuvamile kuphakathi kuka-40000-75000cps. Imisebenzi eyinhloko ye-cellulose ukugcinwa kwamanzi, ukubopha kanye nokugcoba.
Njengoba amafomula we-putty abakhiqizi abahlukahlukene ehlukile, amanye ayi-calcium empunga, i-calcium ekhanyayo, usimende omhlophe, njll., kanti amanye ayimpushana ye-gypsum, i-calcium empunga, i-calcium ekhanyayo, njll. amafomula amabili nawo ahlukene. Isamba esingeziwe singaba ngu-2 ‰-3 ‰.
