Ngokuthuthukiswa kokuqwashisa ngemvelo kanye nezidingo ezikhulayo zemakethe yempahla yokwakha ukuze isebenze kanye nokuvikelwa kwemvelo, izinto zokwakha ezinobungani bemvelo kancane kancane ziye zaba imikhiqizo evamile emkhakheni wokwakha. I-Cellulose ether, njenge-polymer material esebenzayo, idlala indima ebalulekile ezintweni zokwakha ezinobungani bemvelo ngokusebenza kwayo okuhle kakhulu. Kunezinhlobo eziningi ze-cellulose ethers, ezivame kakhulu i-hydroxypropyl methylcellulose (HPMC), i-methyl cellulose (MC), i-hydroxyethyl cellulose (HEC), njll. Asetshenziswa kakhulu ezintweni zokwakha ezingavumelani nemvelo njengezinamathiselo zokwakha, i-putty powder. , udaka oluxutshwe okomile kanye nezingubo ngokulawula ukugeleza kwamanzi, ukuthuthukisa i-rheology nokuthuthukisa izakhiwo zezinto ezibonakalayo.
1. Izici ze-cellulose ethers
I-Cellulose ether iyinhlanganisela ye-polymer ekhishwe emicu yezitshalo yemvelo. Yenziwa yancibilika, yajiya, igcina amanzi futhi yakhiwe ngefilimu ngokusabela kwe-etherification. Izici zayo eziyinhloko zihlanganisa:
Ukugcinwa kwamanzi: I-Cellulose ether inamandla okugcina amanzi amahle kakhulu, angalawula ngokuphumelelayo ukukhululwa kwamanzi ezintweni zokwakha, agweme ukuhwamuka kwamanzi ngokweqile, futhi ngaleyo ndlela athuthukise ukusebenza kokwakhiwa.
Ukuqina: I-Cellulose ether ivame ukusetshenziswa njengesigqila ezintweni zokwakha, ezingathuthukisa i-viscosity yento futhi ithuthukise ukusebenza kwayo ngesikhathi sokwakha.
Ukunamathela: Odakeni oluxutshwe okomile kanye nezinto ezinamathelayo, i-cellulose ether ingasetshenziswa njengesibophezelo ukuze kuthuthukiswe ukunamathela phakathi kwempahla nesisekelo.
Ukulungiswa kwe-Rheological: I-Cellulose ether ingathuthukisa izakhiwo ze-rheological zezinto zokwakha, ukuze zikwazi ukugcina i-fluidity enhle ne-thixotropy ngaphansi kwezimo ezahlukene zokwakha, ezilungele ukwakhiwa nokubunjwa.
I-Anti-sagging: I-Cellulose ether ingathuthukisa indawo evimbela ukugxusha yento, ikakhulukazi uma yakha izindonga eziqondile, ezingavimbela ngempumelelo udaka noma upende ekuwohlokeni.
2. Ukufakwa kwe-cellulose ether ezintweni zokwakha ezingayingeni imvelo
Udaka oluxutshwe okomile
Udaka oluxutshwe okomile luyinto evamile yokwakha evumelana nemvelo, ikakhulukazi esetshenziselwa ukupulasitela odongeni, ukubeka phansi, ukubeka amathayili nezinye izigcawu. I-Cellulose ether isetshenziswa kakhulu odakeni oluxutshwe okomile, ikakhulukazi idlala indima yokugcina amanzi, ukuqina nokubopha. I-Cellulose ether ingenza udaka lukhulule amanzi ngokulinganayo phakathi nenqubo yokomisa, luvimbele ukuqhekeka okubangelwa ukulahlekelwa amanzi ngokweqile, futhi luthuthukise amandla okubopha udaka ukuze kuqinisekiswe amandla alo nokuqina ngemva kokwakhiwa.
Izembatho zezakhiwo
I-Cellulose ether isetshenziswa njenge-ejenti yokuqina kanye ne-ejenti yokugcina amanzi embotsheni yezakhiwo ezisekelwe emanzini ukuze kuthuthukiswe ukusebenza kokwakhiwa kanye nomphumela wokugcina wokuhlanganisa we-coating. Inezakhiwo ezinhle kakhulu zokwakheka kwefilimu kanye nezakhiwo zokulungiswa kwe-rheological, ezingaqinisekisa ukuthi ukugqoka kunokusabalala okuhle ngaphansi kwamathuluzi okwakha ahlukene. Ukwengeza, i-cellulose ether ingaphinde ithuthukise indawo evimbela ukugwedla ye-coating, iyenze ibe mancane amathuba okuthi ihlehle uma isetshenziswa ezindaweni eziqondile, ngaleyo ndlela ithole ukunamathela okufanayo.
Izinamatheliso zamathayela
Izinamatheliso zama-tile ziyisicelo esibalulekile emkhakheni wezinto zokwakha ezinobungani bemvelo. Ama-cellulose ether angathuthukisa ngempumelelo ukugcinwa kwamanzi kanye nezakhiwo ezimelene nokushelela kwezinamathelisa futhi athuthukise amandla okubopha phakathi kwamathayili nesendlalelo sesisekelo. Ngesikhathi sokwakhiwa, ukungezwa kwe-cellulose ethers kuthuthukisa kakhulu ukusebenza kwe-adhesives tile, kuyilapho kuqinisekisa isikhathi eside esivulekile, esilungele abasebenzi bezokwakha ukulungisa.
I-putty powder
I-putty powder isetshenziselwa ukulinganisa nokulungiswa kodonga. Ukugcinwa kwamanzi kwe-cellulose ether kungavimbela ukuqhekeka noma ukuwa okubangelwa ukomisa kwe-putty ngokushesha ngemva kokwakhiwa. Ngesikhathi esifanayo, impahla yayo yokuqina isiza ekuthuthukiseni ukumboza nokushelela kwe-putty, okwenza ukwakhiwa kube lula.
Izinto zokuzilinganisa phansi
Ukusetshenziswa kwe-cellulose ether ezintweni ezizilinganisa phansi ikakhulukazi ukuthuthukisa uketshezi nokugcinwa kwamanzi, ukuqinisekisa ukuthi impahla ingalinganiswa ngokushesha futhi isatshalaliswe ngokulinganayo ngesikhathi sokwakhiwa komhlabathi, futhi ivimbele phansi ekuqhekekeni noma ekufakweni kwesihlabathi okubangelwa ukulahlekelwa kwamanzi.
3. Izinzuzo zemvelo ze-cellulose ether
Umthombo wemvelo, ukukhiqizwa okuhambisana nemvelo
I-Cellulose ether yenziwe nge-cellulose yemvelo futhi ivuseleleka. Ayikho igesi engcolile eyingozi kanye noketshezi olulahlwayo olukhiqizwayo ngesikhathi sokukhiqiza, futhi umthelela emvelweni mncane. Ngaphezu kwalokho, uma kuqhathaniswa nezithasiselo zamakhemikhali ezivamile, i-cellulose ether ayinangozi emzimbeni womuntu futhi ingewonakala ngokwemvelo. Kuyinto impahla eluhlaza ngempela futhi imvelo.
Yehlisa ukusetshenziswa kwamandla okubalulekile futhi uthuthukise ukusebenza kahle kwesakhiwo
I-Cellulose ether ingathuthukisa ukusebenza kokwakhiwa kwezinto zokwakha, yenze ukwakhiwa kwazo kube lula futhi kusheshe, futhi kunciphise ukumosheka kwezinto kanye nokusetshenziswa kwamandla. Ngaphezu kwalokho, ngenxa yokugcinwa kwamanzi kahle, i-cellulose ether inganciphisa isidingo samanzi ekwakhiweni futhi iqhubeke nokulondoloza izinsiza.
Thuthukisa ukuqina kwezinto zokwakha
I-Cellulose ether ingathuthukisa ukuqina kwezinto zokwakha ezinobungani bemvelo, yenze impilo yesevisi yezakhiwo ibe yinde, inciphise isidingo sokukhanda noma ukushintshwa ngenxa yokuguga noma ukulimala kwezinto zokwakha, ngaleyo ndlela inciphise imfucumfucu yezinsiza kanye nokukhiqizwa kwemfucuza yokwakha.
Njengesengezo sezinto zokwakha esinobungani nemvelo, esiphephile nesisebenza ngempumelelo, i-cellulose ether isetshenziswe kabanzi emikhakheni eminingi yokwakha ehambisana nemvelo njengodaka oluxutshwe okomile, izinto zokunamathisela zamathayili, nezingubo zokuklama. Akukwazi nje ukuthuthukisa ukusebenza kokwakhiwa kwezinto zokwakha futhi kuthuthukise ikhwalithi yezinto zokwakha, kodwa futhi kunezinzuzo ezibalulekile zemvelo. Emkhakheni wesikhathi esizayo wezinto zokwakha, ngokuthuthukiswa okuqhubekayo kwezidingo zokuvikelwa kwemvelo, amathemba okusetshenziswa kwe-cellulose ether azoba banzi.
