I-Celsulose Ether uhlobo lwe-polymer ephakeme ye-moleculatic engekho emthethweni. Inezinhlobo ezimbili zezakhiwo ezisuselwa emanzini nezisuselwa ku-solvent. Inemiphumela ehlukile emikhakheni ehlukene. Isibonelo, ezintweni zokwakha amakhemikhali, inemiphumela elandelayo eyinhlanganisela: i-ejenti yokugcina indawo yokuhlala ④Hhilsener Embonini ye-PVC, kuyinto emulsifier futhi ihlakazekile; Embonini yezemithi, kuyisigaxa futhi ngoba i-cellulose inemiphumela ehlukahlukene eyinhlanganisela, futhi ibuye isetshenziswe kabanzi. Ngezansi ngizogxila ekusetshenzisweni nasekusebenzeni kwezimali ze-cellulose ezintweni zokwakha ezinobungane bemvelo.
1. Ku-Latex Paint
Embonini ye-latex Paint, i-hydroxyethyl cellulose kufanele ikhethwe. Ukucaciswa okujwayelekile kwe-viscosity yi-RT30000-50000CPS, kanye nethamo lezethenjwa ngokuvamile lingaba ngu-1.5 ‰ -2 ‰. Umsebenzi oyinhloko we-HydroxyEthyl ku-Latex Paint ukuqina, ukuvikela ukubekezelela ama-picment, usiza ukuhlakazeka kwe-pigment, i-latex, nokuqina, futhi kungathuthukisa ukusebenza kwezakhiwo futhi kufake isandla ekusebenzeni kwezinga lezokwakha: I-Hydroxyyethylllllulose ilula ukuyisebenzisa. Ingachithwa emanzini abandayo namanzi ashisayo, futhi ayithintwa yinani le-PH. Ingasetshenziswa phakathi kwenani le-PH lakwa-2 no-12. Kunezindlela ezintathu ezilandelayo:
I. Faka ngqo ekukhiqizeni:
Le ndlela kufanele ikhethe i-hydroxyethyl cellulose yohlobo olubambezelekile - i-hydroxyyethyl cellulose enesikhathi sokuchithwa kwemizuzu engaphezu kwama-30. Izinyathelo zokusebenzisa zimi ngokulandelayo: ① Faka inani elithile lamanzi amsulwa esitsheni esine-agitator ephezulu ye-agitator enesivinini esiphansi, futhi ngasikhathi sinye futhi ngokungeze i-hydroxyethyl group ku-solution ③ qhubeka uvuse Kuze kube yilapho zonke izinto zokwakha ama-granular zimanzi nge-④ engeza ezinye izengezo ze-alkali, njll.
Ⅱ. Ifakwe ngotshwala bamama:
Le ndlela ingakhetha uhlobo olusheshayo, futhi inomphumela we-anti-celtulose. Inzuzo yale ndlela ukuthi inokuguquguquka okukhulu futhi kungangezwa ngqo kupende we-latex. Indlela yokulungiselela iyafana nezinyathelo ze-①-④.
Ⅲ. Ngokulungiselela izakhiwo ezinjenge-porge:
Njengoba ama-organic solvents ama-solvents ampofu (ama-insoluble) amaqembu ama-hydroxyethyl, ama-porlidge ahlelwe ngalezi zinhlava. Ama-solvents asetshenziswa kakhulu asetshenziswayo angama-organic uketshezi e-Latex Paint Activations, njenge-Ethylene Glycol, i-PlyLlene Glycol kanye nabaqambi befilimu (njenge-diethylene glycol butyl acetate). I-porridge hydroxyyethyl celtulese ingangezwa ngqo kupende. Qhubeka nokuvusa kuze kuchithwe ngokuphelele.
2, ukuklebhula udonga uPretty
Njengamanje, i-putty enobungani bezemvelo evimbelani namanzi emadolobheni amaningi ezweni lami ibiseneliswe ngabantu. Eminyakeni embalwa edlule, ngoba i-putty eyenziwe nge-glue yezokwakha ikhipha igesi ye-formaldehyde futhi ilimaza impilo yabantu, i-glue yokwakha yenziwa nge-polymer ukulungiswa ngokusabela kwe-acetal kwe-vinyl aclohol ne-formaldehyde. Ngakho-ke, lokhu okuqukethwe kuqedwa ngabantu, futhi imikhiqizo yochungechunge ye-cellulose ether ithathelwa indawo yilokhu okuqukethwe, okungukuthi, ukuthuthukiswa kwezinto zokwakha ezinobungane bemvelo, iselula kuwukuphela kwempahla njengamanje.
E-putty engamelana namanzi, ihlukaniswe nge-powder eyomile uPutty kanye no-patety paste. Phakathi kwalezi zinhlobo ezimbili ze-putty, i-methyllulose eguquliwe kanye ne-hydroxypropyll methyl ngokuvamile kukhethwe. Ukucaciswa kwe-Viscosity ngokuvamile kuphakathi kuka-30000-60000CPS. Imisebenzi esemqoka ye-cellulose ku-tutty ukugcinwa kwamanzi, ukubopha nokuthambisa.
Njengoba amafomula ama-putty abakhiqizi ahlukahlukene ahlukile, ezinye ziyi-grey calcium, ukukhanya calcium, usimende omhlophe, njll. . Inani lokungezwa licishe libe ngu-2 ‰ -3 ‰.
Ekwakhiweni kodonga oludongeni uPretty, ngoba ingaphezulu lesisekelo sodonga linokufakwa kwamanzi (izinga lokufakwa kwamanzi kodonga lwezitini lungu-13%, kanti izinga lokufakwa kwamanzi lingu-3-5%), lihambisana Ukuhanjiswa komhlaba wangaphandle, uma i-putty ilahlekelwa amanzi ngokushesha okukhulu, izoholela emihlafwini noma ekususweni kwempuphu kanye nezinye izehlakalo, ngaleyo ndlela yenza buthaka amandla we-putty. Ngalesi sizathu, ukungeza i-cellulose ether kuzoxazulula le nkinga. Kepha ikhwalithi ye-filler, ikakhulukazi ikhwalithi ye-lime calcium, nayo ibaluleke kakhulu. Ngoba i-cellulose inokubona okuphezulu, futhi ithuthukisa ubunye balesi sikhala, ligwema ukugcwala ngesikhathi sokwakha, futhi likhululekile futhi ligcina ukonga ngemuva kokusongelwa.
3. Udaka lukakhonkolo
Udaka lukakhonkolo, ukuze uzuze amandla okugcina, usimende kufanele ukhishwe ngama-hydrate ngokuphelele, ikakhulukazi ehlobo lokwakhiwa kwamanzi, udaka lukakhonkolo lulahlekelwa amanzi ngokushesha, futhi izinyathelo zokugcwaliswa okuphelele zithathwa ukuze zilondoloze futhi zifafaze amanzi. Ukuchithwa kwezinsizakusebenza nokungasebenzi kahle, ukhiye ukuthi amanzi asemgqeni kuphela, futhi i-hydration yangaphakathi isaphelele, ngakho-ke ikhambi lale nkinga ukwengeza i-hydroxypropylylylylylylylylylylylylylylylylylylylylylylylylylylylylylylylylylylylylylylylylylylylylylylylylylylyl metrule Ukucaciswa kwe-Viscosity kuphakathi kuka-20000-60000CPS, inani lokungezwa lingaba ngu-2 ‰ -3 ‰, kanti izinga lokugcina amanzi lingandiswa libe ngaphezu kwama-85%. Indlela yokusebenzisa ngokhonkolo kadaka ukuxuba i-powder eyomile ngokulinganayo bese wengeza amanzi.

Ngokuthuthuka okusheshayo kwemboni yezokwakha, isidingo sabantu sezinto ezintsha zokwakha siyanda usuku nosuku. Ngenxa yokwanda kokuqwashisa kwabantu ngokuvikelwa kwemvelo kanye nokwenza ngcono okuqhubekayo kokusebenza kwezokwakha, imikhiqizo ye-gypsum eyenziwe ngamaveni yathuthuka ngokushesha. Njengamanje, imikhiqizo ejwayelekile ye-gypsum isebenzisa i-gypsum ekhanyayo kakhulu, i-bonding gypsum, i-gypsum yokufaka i-gypsum, i-tile anamathela njalonjalo.
I-Stucco Plasaster uhlobo lwezinto zokufaka ezisezingeni eliphakeme lokudonswa kwezindonga zangaphakathi nophahla. Izindonga ezipulangwe zihlelwe yizo zilungile futhi zibushelelezi, musa ukwehlisela i-powder, ngesibopho ngokuqinile kuya engxenyeni engezansi, ungabi nokuqhekeka bese uwa phansi, futhi ube nokumelana nomlilo; Usonga lokubopha luhlobo lodaka. Uhlobo olusha lwesakhiwo seBhodi iBhodi Adhesive izinto ezinamathelayo ezenziwe nge-gypsum njengezinto zesisekelo futhi zingeza izithasiselo ezahlukahlukene. Ilungele ukubopha izibopho phakathi kwezinto ezahlukahlukene zokwakha udonga. Akunangqondo, ayinambitha, inezici zamandla okuqala, ukusethwa okusheshayo kanye nokubopha okuqinile, futhi kuyinto esekelayo yokwakhiwa kwamabhodi okwakha amabhulokhi;
Le mikhiqizo ye-gypsum inochungechunge lwemisebenzi ehlukene, ngaphezu kweqhaza le-gypsum kanye nabasizi abahlobene, inkinga enkulu ukuthi i-cellulose auxiliary idlala indima eholayo. Njengoba i-gypsum ihlukaniswe nge-anhydrite ne-hemihydrate gypsum, i-gypsum ehlukile inemiphumela ehlukile ekusebenzeni komkhiqizo, ukuqina, ukugcinwa kwamanzi kanye nokubuyiselwa emuva kuthola ikhwalithi yezinto zokwakha ze-gypsum. Inkinga evamile yalezi zinto zokwakha ayiwukuqhekeka okungekho, futhi amandla okuqala awatholakali. Ukuxazulula le nkinga, kuyinkinga yokukhetha uhlobo lwe-cellulose kanye nendlela yokusebenzisa eyinhlanganisela ye-retard. Kulokhu, i-methyl noma i-hydroxypropylylyl methyl 30000 ngokuvamile kukhethwe. -60000CPS, inani lokungezwa liphakathi kuka-1.5 ‰ -2 ‰, ukugxila kwe-cellulose ukugcinwa kwamanzi, ukubuyiselwa emuva nokuthambisa.
Kodwa-ke, akunakwenzeka ukuncika ku-cellulose ether njenge-retarder, futhi kuyadingeka ukwengeza i-retarder ye-citric acid ukuxuba nokuyisebenzisa ukuze amandla okuqala angeke athinteke.
Izinga lokugcina amanzi ngokuvamile libhekisela ekulahlekelweni kwemvelo kwamanzi lapho kungekho khona ukumuncwa kwamanzi kwangaphandle. Uma udonga lusomile kakhulu, ukumuncwa kwamanzi kanye nokuhwamuka kwemvelo endaweni eyisisekelo kuzodala ukuthi lokhu kulahlekelwa amanzi ngokushesha okukhulu, futhi kuyavela nokuqhekeka kuzokwenzeka.
Le ndlela yokusebenzisa ixubene ne-powder eyomile. Uma isixazululo silungiselelwe, sicela ubheke indlela yokulungiselela ikhambi.
5. Isidumbu sodaka
I-Thermal Insulation Metar iluhlobo olusha lwento engaphakathi yodonga lokufakwa odongeni esifundeni esisenyakatho. Kuyinto yodonga lodonga elakhiwa ngezinto zokufaka okushisayo, udaka kanye ne-binter. Kulokhu okubonakalayo, i-cellulose idlala indima ebalulekile eBonding namandla andayo. Ngokuvamile khetha i-methyl celtule
6. I-ejenti ebonakalayo
I-ejenti ye-interface i-HPNC20000CPS, kanye ne-tile adhesive ingaphezulu kwama-60000cps. Emenzeni ebonakalayo, isetshenziswa ikakhulukazi njengomuntu omkhulu, ongathuthukisa amandla ashukumisayo kanye nokuphikiswa komcibisholo.
