I-Cellulose Ether iyi-polymer yokwenziwa engeyona eye-ionic, okuyi-soluble yamanzi futhi i-solvent-soluble. Inemiphumela ehlukile emikhakheni ehlukene. Isibonelo, ezintweni zokwakha amakhemikhali, inemiphumela elandelayo eyinhlanganisela:
I-Agent egciniwe yamanzi,
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.
ku-latex upende
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 weHydroxYethyl ku-Latex Paint ukuqina, uvikele ukuvezwa kombala, usiza ukuhlakazeka kwe-pigment, ukuqina kwe-latex, futhi kwandise ukubonwa kwezakhi, okunomthelela ekusebenzeni kwalolokwakha: I-Hydroxyethyl cellulose ilula ukuyisebenzisa. Ingachithwa emanzini abandayo namanzi ashisayo, futhi ayithintwa yinani le-PH. Ingasetshenziswa ngokuphepha phakathi kwe-PI Value 2 no-12. Izindlela zokusebenzisa zimi ngokulandelayo:
I. Faka ngqo ekukhiqizeni
Ngale ndlela, uhlobo lwe-hydroxyethyl cellulose kufanele kukhethwe, 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.
ku-tutty
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. Amafomula amabili ahlukile. Inani elingeziwe lingaba 2 ‰ -3 ‰.
