I-Cellulose EtherI-polymer ephakeme engeyona eye-moleculatic ephezulu ye-moleculatic, okungukuthi ancibilika amanzi futhi i-solvent-soluble. Inemiphumela ehlukile emikhakheni ehlukene. Isibonelo, ezintweni zokwakha amakhemikhali, inemiphumela elandelayo eyinhlanganisela:
① I-ejenti yokugcina amanzi, ②Thiikener, impahla ebilayo, ④FILMM yakha impahla,
⑤Ber
Embonini ye-polyvinyl chloride, kuyinto emulsifier futhi ihlakazekile; Embonini yezemithi, kuyisigaxa kanye nohlaka lokukhishwa kancane futhi olulawulwa ukukhishwa, njll. Ngoba i-cellulose inemiphumela ehlukahlukene yenhlanganisela, uhlelo lokusebenza lwayo insimu ibuye ibe ngcono kakhulu. Okulandelayo, ngizogxila ekusetshenzisweni nasekusebenzeni kwe-cellulose ether ezintweni ezahlukahlukene zokwakha.
In upende we-latex
Embonini ye-latex Paint, ukukhetha i-hydroxyethyl cellulose, ukucaciswa okujwayelekile kokubonakala okulinganayo kungu-30000-50000CPS, okuhambisana nokucaciswa kwe-HBR250, kanye nethamo lezethenjwa ngokuvamile lingaba ngu-1.5 ‰ -2 ‰. Umsebenzi oyinhloko we-HydroxyEthyl ku-Latex Paint ukuqina, ukuvikela ukubekeka kwe-pigment, ukusiza ukuhlakazeka kwe-pigment, ukuqina kwe-latex, futhi kukhuphule ukubonwa kwezakhi, okuwusizo ekusebenzeni kokwakha : I-Hydroxyethyl cellulose ilula ukuyisebenzisa. Ingachithwa emanzini abandayo noma emanzini ashisayo, futhi ayithintwa yinani le-PH. Ingasetshenziswa ngokuphepha phakathi kwe-PI Value 2 no-12. Izindlela zokusebenzisa zimi ngokulandelayo:
1. Faka ngqo ekukhiqizeni
Le ndlela, uhlobo lwe-hydroxyyethyl cellulose kufanele ikhethwe, kanye ne-hydroxyethyl cellulose enesikhashana sokuchithwa kwemizuzu engaphezu kwama-30. Izinyathelo zimi ngalendlela elandelayo: ① Beka inani elithile lamanzi amsulwa esitsheni esifakwe nge-agaritator ephezulu-② Qala ukushukumisa ngokuqhubekayo ngejubane eliphansi, futhi ngasikhathi sinye engeza kancane i-hydroxyethyl gerol kwisisombululo ngokulinganayo. Zonke izinto ze-granular zigcwele ezinye izengezo nezithasiselo eziyisisekelo, njll.
2. Ifakwe ngotshwala bamama ukuze isetshenziswe kamuva
Le ndlela ingakhetha uhlobo olusheshayo, futhi ine-anti-mbumba ye-cellulose. Inzuzo yale ndlela ukuthi inokuguquguquka okuthe xaxa futhi kungangezwa ngqo ku-Latex Paint. Indlela yokulungiselela iyafana nezinyathelo ①-④.
3. Kwenze kube iphalishi ukuze isetshenziswe kamuva
Njengoba ama-organic solvents ama-solvents ampofu (insoluble) ye-hydroxyethyl, lezi zinhlava zingasetshenziswa ukwenza iphalishi. I-solvents esetshenziswa kakhulu ye-organic uketshezi olwenziwayo ekwakhekeni kwepende ye-latex, njenge-ethylene glycol, i-plylene glycol, kanye nama-ejenti akha amafilimu (njenge-diethylene glycol butyl acetate). I-porridge hydroxyyethyl celtulese ingangezwa ngqo kupende. Qhubeka nokuvusa kuze kuchithwe ngokuphelele.
In putty
Njengamanje, emadolobheni amaningi ezweni lakithi, indawo yokulwa namanzi nokungamelana nokungamelana nokungamelana nobuntu kubhekwe ngokuyisisekelo ngabantu. Kukhiqizwa ukusabela kwe-acetal kweVinyl Alcohol kanye ne-formaldehyde. Ngakho-ke, lokhu okuqukethwe kuqedwa kancane kancane ngabantu, futhi imikhiqizo yeCellulose ether ether isetshenziselwa ukufaka le nto. Lokho kusho ukuthi, ukuthuthukiswa kwezinto zokwakha ezemvelo zokwakha, amaselula okwamanje okuwukuphela kwento.
E-putty engamelana namanzi, ihlukaniswe ngezinhlobo ezimbili: i-dry powder putty ne-putty paste. Phakathi kwalezi zinhlobo ezimbili ze-putty, methylllslese kanye ne-hydroxypropyll methy kufanele kukhethwe. Ukucaciswa kwe-Viscosity ngokuvamile kuphakathi kuka-40000-75000cps. Imisebenzi esemqoka yeselula yokugcinwa kwamanzi, ukubopha kanye nokuthambisa.
Njengoba amafomula ama-putty abakhiqizi ahlukahlukene ahlukile, ezinye ziyi-grey calcium, ukukhanya calcium, usimende omhlophe, njll. Ngamafomula amabili ahlukile. Inani elingeziwe lingaba 2 ‰ -3 ‰.
