I-Cellulose ether iyi-polymer engeyona i-ionic semi-synthetic, encibilika emanzini futhi encibilika.Inemiphumela ehlukene ezimbonini ezahlukene.Isibonelo, ezintweni zokwakha zamakhemikhali, zinemiphumela eyinhlanganisela elandelayo: ① i-ejenti yokugcinwa kwamanzi ② ukuqina ③ impahla yokulinganisa ④ isakhiwo sokwenza ifilimu ⑤ i-binder;embonini ye-polyvinyl chloride, i-emulsifier ne-dispersant;embonini yezemithi, iyi-agent ehlanganisayo ne-buffering Khipha izinto zamathambo, njll., ngoba i-cellulose inemiphumela ehlukahlukene eyinhlanganisela, ngakho-ke izinkambu zayo zokufaka isicelo nazo zibanzi kakhulu.Okulandelayo, ngizogxila ekusetshenzisweni nasekusebenzeni kwe-cellulose ether ezintweni zokwakha zokuvikela imvelo.
1. Ngopende we-latex
Embonini yokupenda ye-latex, i-hydroxyethyl cellulose kufanele ikhethwe.Ukucaciswa okujwayelekile kwe-viscosity yi-RT30000-50000cps, futhi isilinganiso sereferensi ngokuvamile simayelana ne-1.5 ‰-2 ‰.Umsebenzi oyinhloko we-hydroxyethyl kupende we-latex uwukuqina, ukuvimbela ukugeleza kwe-pigment, ukusiza ukuhlakazeka, i-latex, nokuzinza kwe-pigment, nokwandisa i-viscosity yengxenye, okuwusizo ekusebenzeni kokulinganisa kokwakhiwa: I-hydroxyethyl Ethyl cellulose kulula ukuyisebenzisa.Ingancibilika emanzini abandayo nasemanzini ashisayo, futhi ayithinteki ngenani le-pH.Ingasetshenziswa phakathi kwenani le-pH lika-2 no-12. Kunezindlela ezintathu zokusebenzisa:
I. Engeza ngokuqondile ekukhiqizeni:
Le ndlela kufanele ikhethe uhlobo olubambezelekile lwe-hydroxyethyl cellulose - i-hydroxyethyl cellulose enesikhathi sokuhlakazeka esingaphezu kwemizuzu engama-30.Izinyathelo zimi kanje: ① Faka inani elithile lamanzi ahlanzekile esitsheni esifakwe isishicileli esishear kakhulu ② Qala ukunyakazisa ngokuqhubekayo ngesivinini esiphansi, futhi ngesikhathi esifanayo wengeze kancane kancane iqembu le-hydroxyethyl esixazululweni ngokulinganayo ③Qhubeka nokunyakazisa kuze kucwiliswe zonke izinto ze-granular ④Engeza ezinye izinsiza nezithasiselo eziyisisekelo, njll. ⑤Govuza kuze kube yilapho wonke amaqembu e-hydroxyethyl ehlakazeka ngokuphelele, bese Engeza ezinye izingxenye kufomula bese ugaya kuze kube umkhiqizo ophelile.
Ⅱ.Ifakwe utshwala bomama 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.Yilungiselele iphalishi ukuze lisetshenziswe 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.
2. Odongeni lokukhuhla i-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 eguquliwe kanye ne-hydroxypropyl methyl kufanele kukhethwe.Ukucaciswa kwe-viscosity ngokuvamile kuphakathi kuka-30000-60000cps.Umsebenzi oyinhloko we-cellulose ku-putty ukugcinwa kwamanzi, ukubopha, ukugcoba nokunye.
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 ‰.
Ekwakhiweni kwe-wall scraping putty, njengoba isisekelo sodonga sinezinga elithile lokumuncwa kwamanzi (izinga lokumuncwa kwamanzi odongeni lwezitini liyi-13%, futhi izinga lokumuncwa kwamanzi likakhonkolo liyi-3-5%), kuhambisana nokuhwamuka kwezwe langaphandle, uma i-putty ilahlekelwa amanzi ngokushesha okukhulu , Kuzoholela ekuqhekekeni noma ekususweni kwempushana, okuzokwenza buthaka amandla e-putty.Ngakho-ke, ukwengeza i-cellulose ether kuzoxazulula le nkinga.Kodwa ikhwalithi ye-filler, ikakhulukazi ikhwalithi ye-ash calcium nayo ibaluleke kakhulu.Ngenxa ye-viscosity ephezulu ye-cellulose, i-buoyancy ye-putty nayo iyathuthukiswa, futhi umkhuba wokuwohloka ngesikhathi sokwakhiwa nawo uyagwenywa, futhi kuba ntofontofo futhi konga umsebenzi ngemuva kokukhuhla.
3. Udaka lukakhonkolo
Odakeni lukakhonkolo, ukuze kuzuzwe amandla okugcina, usimende kumele ube namanzi ngokuphelele.Ikakhulukazi ekwakhiweni kwehlobo, udaka lwekhonkrithi lulahlekelwa amanzi ngokushesha, futhi izilinganiso ze-hydration ephelele zisetshenziselwa ukugcina nokufafaza amanzi.Ukuchithwa kwezinsiza kanye nokusebenza okungalungile, okubalulekile ukuthi amanzi aphezu komhlaba kuphela, futhi i-hydration yangaphakathi namanje ayiphelele, ngakho-ke isisombululo sale nkinga ukwengeza i-hydroxypropyl methylcellulose noma i-methylcellulose kukhonkolo yodaka, Ukucaciswa kwe-viscosity kuphakathi 20000–60000cps, inani elingeziwe lingaba ngu-2 ‰–3‰, futhi izinga lokugcinwa kwamanzi lingakhuphuka libe ngaphezu kwama-85%.Indlela yokusebenzisa ukhonkolo wodaka ukufaka amanzi ngemva kokuba impushana eyomile ixutshwe ngokulinganayo.
4. Ekufakeni i-gypsum, ukubopha i-gypsum, i-caulking gypsum
Ngokuthuthuka okusheshayo kwemboni yezokwakha, isidingo sabantu sezinto zokwakha ezintsha sikhula usuku nosuku.Ngenxa yokwanda kokuqwashisa kwabantu ngokuvikelwa kwemvelo kanye nokuthuthukiswa okuqhubekayo kokusebenza kahle kokwakhiwa, imikhiqizo ye-gypsum kasimende ithuthuke ngokushesha.Njengamanje, imikhiqizo evame kakhulu ye-gypsum i-gypsum yokunamathisela, i-gypsum eboshiwe, i-gypsum ehlotshisiwe, ne-adhesive tile.
I-plastering gypsum iyikhwalithi ephezulu yokukhonkoloza kwezindonga zangaphakathi nophahla.Udonga olunamekwe ngalo luhle futhi lubushelelezi, aluwehlisi impushana, luboshwe ngokuqinile esisekelweni, aluqhekeki futhi luwa, futhi lunomsebenzi wokuvikela umlilo;i-gypsum eboshiwe iwuhlobo olusha lokunamathisela kwebhodi lokukhanya lokwakha into enamathelayo eyenziwe nge-gypsum njengento eyisisekelo futhi ingeza izithasiselo ezihlukahlukene.Ifanele ukuhlangana phakathi kwezinto ezihlukahlukene zezindonga zokwakha ezingaphili.Ayinabuthi, ayinambitheki, Izici ezifana namandla okuqala, ukusetha okusheshayo, nokubopha okuqinile, iyinto esekelayo yamaphaneli okwakha nokwakhiwa kwamabhulokhi;i-ejenti ye-gypsum caulking iyisigcwalisi segebe phakathi kwamaphaneli e-gypsum kanye nesigcwalisi sokulungisa izindonga nokuqhekeka.
Le mikhiqizo ye-gypsum inochungechunge lwemisebenzi ehlukene.Ngaphezu kwendima ye-gypsum kanye nezigcwalisi ezihlobene, inkinga eyinhloko ukuthi izithasiselo ze-cellulose ether ezengeziwe zidlala indima ehamba phambili.Ngenxa yokuthi i-gypsum ihlukaniswe yaba yi-gypsum anhydrous kanye ne-hemihydrate gypsum, i-gypsum ehlukene inemiphumela ehlukene ekusebenzeni komkhiqizo, ngakho-ke ukuqina, ukugcinwa kwamanzi kanye nokuvinjelwa kunquma izinga lezinto zokwakha ze-gypsum.Inkinga evamile yalezi zinto ezisetshenziswayo ukugoba nokuqhekeka, futhi amandla okuqala awakwazi ukufinyelelwa.Ukuxazulula le nkinga, ukukhetha uhlobo lwe-cellulose kanye nendlela yokusebenzisa inhlanganisela ye-retarder.Mayelana nalokhu, i-methyl noma i-hydroxypropyl methyl 30000 ngokuvamile ikhethwa.-60000cps, inani elengeziwe liphakathi kuka-1.5 ‰–2 ‰, i-cellulose isetshenziselwa kakhulu ukugcina amanzi kanye nokunciphisa ukuthambisa.
Kodwa-ke, akunakwenzeka ukuthembela ku-cellulose ether njenge-retarder, futhi kuyadingeka ukwengeza i-citric acid retarder ukuxuba nokusebenzisa ngaphandle kokuthinta amandla okuqala.
Ukugcinwa kwamanzi ngokuvamile kubhekisela ekutheni angakanani amanzi azolahleka ngokwemvelo ngaphandle kokumuncwa kwamanzi ngaphandle.Uma udonga lome kakhulu, ukumuncwa kwamanzi kanye nokuhwamuka kwemvelo endaweni engaphansi kuzokwenza izinto zilahlekelwe amanzi ngokushesha kakhulu, futhi ukumboza nokuqhekeka nakho kuzokwenzeka.
Le ndlela yokusetshenziswa ixubene nempushana eyomile.Uma ulungisa isixazululo, sicela ubheke indlela yokulungiselela ikhambi.
5. I-thermal insulation mortar
I-insulation mortar iwuhlobo olusha lwempahla yokufaka udonga lwangaphakathi esifundeni esisenyakatho.Kuyimpahla yodonga ehlanganiswe ngezinto zokufakelwa, udaka kanye ne-binder.Kule nto, i-cellulose idlala indima ebalulekile ekuhlanganiseni nasekukhuliseni amandla.Ngokuvamile khetha i-methyl cellulose ene-viscosity ephezulu (mayelana ne-10000eps), umthamo ngokuvamile uphakathi kuka-2 ‰-3 ‰), futhi indlela yokusetshenziswa iwukuba ukuxubana kwe-powder eyomile.
6. I-ejenti yesixhumi esibonakalayo
I-adhesive tile kufanele ibe ngaphezu kuka-60,000cps, futhi kufanele isetshenziswe njenge-thickener ku-ejenti yesixhumi esibonakalayo, engathuthukisa amandla aqinile namandla okulwa nomcibisholo.
