I-Cellulose ether i-non-ionic semi-synthetic high molecular polymer, encibilika emanzini futhi encibilika.Inemiphumela ehlukene ezimbonini ezahlukene.Isibonelo, ezintweni zokwakha zamakhemikhali, zinemiphumela elandelayo eyinhlanganisela:
①Umenzeli ogcina amanzi
②I-Thickener
③Leveling
④Ukwakhiwa kwefilimu
⑤ Isibopho
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.
1. 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 ze-granular zicwilisiwe ④Engeza ezinye izithasiselo nezithako eziyisisekelo, njll. ⑤Guqula kuze kube yilapho wonke amaqembu e-hydroxyethyl ehlakazeka ngokuphelele, bese Engeza ezinye izingxenye kufomula bese ugaya kuze kube umkhiqizo ophelile.
Ⅱ.Ifakwe notshwala kamama 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.
Ⅲ.Yenza iphalishi ozolisebenzisa 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 ugovuze kuze kuqedwe ngokuphelele.
Okwesibili, ku-wall scraping 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 e-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., ngakho ukucaciswa, i-viscosity kanye nokungena kwe-cellulose amafomula amabili nawo ahlukene.Isamba esingeziwe singaba ngu-2 ‰-3 ‰.
