Yiziphi izinzuzo ze-cellulose afers ngokwemigomo yokuqina nokusebenza?

I-Cellule Kunezinhlobo ezahlukene ze-cellulose iziphathamandla, ezijwayelekile zifaka i-hydroxypropylllylylylylylyll methylcellulose (HPMC), i-hydroxyethyl cellulose (HEC) ne-methylcellulose (MC). Kuzicelo ezahlukahlukene, izithambiso ze-cellulose zikhombisile izinzuzo ezibalulekile ngokuya ngokuqina nokusebenza, zibe yingxenye ebalulekile ekwenzeni ngcono ikhwalithi yezinto ezibonakalayo nempilo yenkonzo.

1. Thuthukisa ukusebenza kokwakha

Ensimini yezinto zokwakha, izimpikiswano ze-cellulose zivame ukusetshenziswa njengabakhulu, ama-ejenti agcina amanzi kanye nama-linders. Ngezinto zodaka, ze-gypsum kanye nokwenza usimende, umphumela wokuqina we-cellulose ether wenza ukuba kube lula ngokwezinto ezibonakalayo kanye nepulasitiki ngesikhathi sokwakha, ukugwema izinkinga zokuphamba nezinhlaka. I-Celsulose Ether ibuye ithuthukise amandla abusayo kwezinto ezibonakalayo, ukuqinisekisa ukuthi lokho okubonakalayo kungasatshalaliswa ngokulinganayo ngesikhathi sokwakha futhi kube nokunamathela okungcono ku-subthesion engcono.

IHydroxypropyl Methylcellulose (HPMC) ingathuthukisa kakhulu ukusebenza kokusebenza kodaka, okwenza kube lula ukufaka isicelo futhi mancane amathuba okuthi slide phansi, ikakhulukazi ekwakhiweni okuthe mpo. Ngaphezu kwalokho, umphumela wokugcina kabusha we-cellulose ether ungangezelela isikhathi sokusebenza sodaka, esizuzisa ukwakhiwa okuqondile kwamaphrojekthi anzima. Lezi zici zithuthukisa ukusebenza kahle kokwakha kanye nekhwalithi ngokuya ngokunciphisa imfucuza yezinto ezibonakalayo namaphutha wokwakha.

2. Ukugcinwa kwamanzi okuhle kakhulu

Enye yezinto ezibalulekile ze-cellulose afers yizakhiwo zazo ezinhle kakhulu zokugcina amanzi. Ukugcinwa kwamanzi kusho amandla we-cellulose ether ukudonsa nokugcina umswakama kulokho okubonakalayo, ukuvimbela ukuhwamuka ngaphambi kwesikhathi noma i-sperage yomswakama, ngaleyo ndlela uqinisekise amandla nokuqina kwezinto ngemuva kokwakha. Ezintweni zokwakha ezinjengemikhiqizo esekwe ku-clean-based and gypsum, umphumela wokugcina amanzi we-cellulose ether uqinisekisa ukuthi amanzi angabamba iqhaza ngokugcwele kwinqubo yokusabela ngesikhathi sokuphendula, ukugwema ukuqhekeka kwezinto ezibonakalayo namandla anganele okubangelwa ukulahleka kwamanzi ngaphambi kwesikhathi.

Izakhiwo zokugcina amanzi zibaluleke kakhulu ekwakhiweni kwesendlalelo. Isibonelo, ngesikhathi senqubo yokuvutha, izimpi ze-cellulose zingasiza ukuvikela umswakama odongeni kusuka ekulahlekelweni kakhulu, ngaleyo ndlela kuthuthukiswe ukunamathela nokuqina kwamathayili. Ngokufanayo, emkhakheni wezembatho, ama-cellulose afers angavimbela ukuhwamuka ngaphambi kwesikhathi komswakama, okuvumela ukuhlanganiswa kokwenza umfaniswano nomnyene, ukunweba impilo ye-coating kanye nokunciphisa isidingo sokulungiswa kwakamuva.

3. Thuthukisa ukumelana kwesimo sezulu kwezinto zokwakha

Ukusetshenziswa kwe-cellulose TETERS kungathuthukisa futhi isimo sezulu sokwaziswa, okusho ukumelana kwaso ezimweni zemvelo njengokuswakama, imisebe ye-UV, isimo sezulu kanye namazinga okushisa aphezulu. Lokhu kubaluleke kakhulu ekulweni nesikhathi eside sezinto zokwakha. Isibonelo, ukusetshenziswa kwe-CelculOse Tather in Coatings kungathuthukisa ikhwalithi eyenziwe ngamafilimu okuhlanganisa futhi kwandise ubungako bokuhlanganiswa, ngaleyo ndlela kuthuthukise ukumelana nokuhlangana kwe-ultraviolet kanye nokuvimbela ukufiphala nokuguga.

Ezintweni ezenzelwe amasimende, i-cellulose ether ingathuthukisa ukugcinwa kwamanzi, yehlise umthelela wokucwilisa wamanzi ngesikhathi sokuqinisa usimanzi, futhi wehlise ubungozi bokuqhekeka, ngaleyo ndlela kuthuthukise ukumelana kwe-free-thaw kanye nokumelana nesimo sezulu. Lokhu kuvumela isakhiwo ukuthi silondoloze ubuqotho bayo kanye nama-aesthetics isikhathi eside esimweni sezulu esinzima.

I-4. Ukulungiswa okuhle kakhulu nokuqina kwe-Rheology

Umphumela wokuqina we-cellulose ether kwisixazululo samanzi uyakuvumela ukuthi uguqule izakhiwo zesimbozo sezinto ezibonakalayo (njengokubonakala, ngaleyo ndlela uthuthukise ukuqina kanye nokusebenziseka kalula kokuqukethwe. Ekuhlolweni nasezindebeni, izithambisi ze-cellulose zilungisa i-viscosity yopende ukuze uqinisekise ukuthi ayihlanganisi noma idonsa ngesikhathi sokusebenzisa futhi yakha. Lokhu akugcini nje ngokuthuthukisa ukulawulwa kokwakha, kepha futhi kukhulisa kakhulu ukumelana nokugqoka kanye nokumelana nokuqhekeka kwe-coating.

I-Cellulose Tashers ibuye idlale indima ebalulekile ezintweni zokuzivikela ezingezansi. Imisebenzi yayo yokuqina kanye ne-herological ukuguqulwa iqinisekisa ukuthi lokho okubonakalayo kugcina ingozi enhle kanye nezakhiwo ezizimele ngesikhathi senqubo yokuthela, kunciphisa ukukhiqizwa kwamabhamuza kanye nokulimazeka, futhi ekugcineni kuthuthukisa ukukhuluphala nokuqina phansi.

5. Thuthukisa ukumelana nokuqhekeka kwezinto zokwakha

Ukugcinwa kwamanzi kanye nemiphumela yokuqina ye-cellulose ether kusiza ukulawula ijubane lokusoma kokuqukethwe okuqukethwe futhi ugweme ukuncipha kanye nokuqhekeka kwezinkinga ezibangelwa ukulahleka komswakama ngokweqile. Ikakhulu ezintweni zodaka zezinto zodaka kanye nosimende, i-cellulose ether ingahlakaza ngokulinganayo umswakama kokuqukethwe futhi inciphise ukwenzeka kwama-shrinkage imifantu. Ngaphezu kwalokho, izakhiwo zayo ezithuthukile ezithuthukisiwe nazo zinika amandla okuqukethwe kubudlelwano obungcono nge-substrate futhi bathuthukise ukumelana nokuqhekeka kwesakhiwo sonke.

Ezintweni ezenzelwe ama-gypsum, izithambiso ze-cellulose zivimbela ukuqhekeka komhlaba okubangelwa ukulahleka kwamanzi okusheshayo, okwenza udonga kanye nophahla izimbobo ezizinzile zizinzile futhi zibusheleleke ngesikhathi sokomiswa. Lokhu kumelana nokuqhekeka akugcini nje ngokuthuthukisa ikhwalithi yokubukeka nje, kepha futhi kunweba impilo yayo yenkonzo.

6. Thuthukisa ukumelana nokugqwala nokuphikiswa kwamakhemikhali

I-Cellulose Afers nayo ingathuthukisa ukugqwala kanye nokuphikiswa kwamakhemikhali kwezinto zokwenziwa kwezicelo ezithile. Ngokwenza umganingi wezinto ezibonakalayo kanye nokungamelananga amanzi, ama-cellulose akwazi ukunciphisa ngempumelelo ukuhlaselwa kwamakhemikhali ayingozi noma umswakama obonakalayo. Lokhu kubaluleke kakhulu ezindaweni ezithile ezikhethekile, njengezitshalo zamakhemikhali, izindawo zasolwandle noma izindawo eziphakeme zomswakama.

Ukusetshenziswa kwezithambisi ze-cellulose ezimbozweni ezingavunyelwe kungaphili nje kuthuthukisa ukuqina kwamakhemikhali, kepha futhi kuthuthukisa ukumelana namakhemikhali afana nama-acids, i-alkali kanye nosawoti, ukunciphisa izindleko zokulungiswa nokubuyiselwa.

7. Ukuvikelwa okuluhlaza kwezemvelo kanye nentuthuko esimeme

I-Cellulose Ether empeleni iyinto eluhlaza okwesikhashana nemvelo enobungane ngoba itholakala kwisitshalo semvelo se-cellulose futhi iyinto engathandeki. Uma kuqhathaniswa nezinto zokwenziwa ze-polymer, izithambiso ze-cellulose zinomthelela omncane emvelweni futhi zingadedeli izinto eziyingozi ngesikhathi senqubo yokukhiqiza. Ngakho-ke, ukusetshenziswa okubanzi kwezinhlangano ze-cellulose kuhlangabezana nezidingo zamanje zokuvikelwa kwemvelo kanye nokuthuthuka okuqhubekayo embonini yezokwakha.

Izinzuzo ze-cellulose afers ngokwemigomo yokuqina nokusebenza zikhonjiswa ikakhulukazi ekugcinweni kwazo kwamanzi okuhle, ukuqina, ukunamathela kanye nokumelana nesimo sezulu. Akugcini nje ngokuthuthukisa ukusebenza kwezokwakha kwezinto zokwakha, kepha futhi kuthuthukisa kakhulu ukumelana nokuqhekeka kwezinto ezibonakalayo, ukuqina nokuphikiswa kokugqwala, futhi kunwebe impilo yenkonzo yezinto ezibonakalayo. Ngaphezu kwalokho, izakhiwo eziluhlaza eziluhlaza nezemvelo ze-cellulose ether nazo zikwenza kube yingxenye ebalulekile yokuthuthukiswa kwezinto zokwakha ezizayo.
