I-Hydroxypropyllth methylcellulose (hpmc) plaster-based plasters kanye nemikhiqizo ye-gypsum

I-Hydroxypropyl Methylcellulose (HPMC), njenge-ether evamile ye-cellulose, iya ngokuya isetshenziswa ezintweni zokwakha, ikakhulukazi ku-gypsum-based plaster kanye nemikhiqizo ye-gypsum. I-HPMC ine-solubility yamanzi enhle, ukuqina, ukugcinwa kwamanzi kanye nezakhiwo ezakha amafilimu, ngakho-ke zidlala indima ebalulekile ekukhiqizweni nasekusetshenzisweni kwemikhiqizo ye-gypsum.

Izici eziyisisekelo ze-hydroxypropyllylylyll (hpmc)
I-HPMC iyi-ether engeyona eye-celvule ye-moulsose, eqanjwe ngemuva kokwethulwa kwe-hydroxypropyl kanye namaqembu we-methyl molecule. Izakhiwo zalo eziyisisekelo zifaka:

I-Solubinity: I-HPMC ingancipha ngokushesha emanzini abandayo ukwakha isixazululo esibonakalayo noma esincanyana se-turmid.
Ukuqina: I-HPMC inomphumela omuhle kakhulu wokuqina futhi ingakhuphula ukubonwa kwesixazululo.
Ukugcinwa kwamanzi: I-HPMC ingahlala inomswakama isikhathi eside lapho amanzi evele avele, ukuvimba amanzi ekulahlekelweni ngokushesha okukhulu.
Ukukhamulwa kwefilimu: I-HPMC ingakha ifilimu eguquguqukayo futhi esobala ngemuva kokomiswa.
Lezi zici zenza i-hpmc i-HPMC isengezo esibalulekile ku-gypsum-based plaster kanye nemikhiqizo ye-gypsum.

Ukusetshenziswa kwe-HPMC ku-gypsum-based plaster
Upulani osuselwa ku-gypsum uyisisekelo esisetshenziswa ngaphakathi nangaphandle kokuhlobisa odongeni ezakhiweni zanamuhla, ikakhulukazi akhiwa nge-gypsum ye-semi-hydrate, aggregates kanye nezithasiselo ezahlukahlukene. Ukusetshenziswa kwe-HPMC ku-gypsum-based sopulalta kuboniswa ikakhulukazi ezintweni ezilandelayo:

Umphumela Wokuqina
Umphumela Wezokugcina Amanzi
Ukwenza ngcono ukusebenza kokwakha
Ukumelana nokuqhekeka: Ngokwandisa ukuguquguquka kodaka, i-HPMC inganciphisa ngempumelelo ukuqhekeka okubangelwa ukushwabana futhi kwandise impilo yenkonzo yesendlalelo sokuhlobisa.

Ukusetshenziswa kwe-HPMC emikhiqizweni ye-Gypsum
Ngaphezu kohlelo lokusebenza lwayo ku-Gypsum-based Plaster, i-HPMC nayo isetshenziswa kabanzi emikhiqizweni ehlukahlukene ye-gypsum, efana ne-gypsum, amamodeli we-gypsum, njll. In inqubo yokukhiqiza, i-HPMC ingaletha imiphumela ebalulekile:

Ukuguqulwa kanye nokuqina: Ukungeza i-HPMC ku-Gypsum Slurry kungathuthukisa ukubonakala kwayo kanye ne-Thixotropy, yenza ama-slurry anokugcwaliswa okungcono kokubumba, anciphise ama-bubbles kanye namaphutha, futhi athuthukise ikhwalithi ephezulu yomkhiqizo ophelile.
Thuthukisa ubulukhuni namandla: Isakhiwo sefilimu esakhiwe yi-HPMC ngesikhathi senqubo eqinile singakhuphula ukuguquguquka kanye nokumelana nomthelela wemikhiqizo ye-gypsum futhi kunciphise ukulimala ngesikhathi sokuhamba nokufakwa.
Thuthukisa ukugcinwa kwamanzi: I-HPMC ingagcina isimo esimanzi isikhathi eside ngesikhathi senqubo yokomisa yemikhiqizo ye-gypsum, ukugwema ukuqhekeka nokukhubazeka okubangelwa ukomisa okusheshayo.
Ukubumba okufanayo: I-HPMC ingenza ama-slurry we-gypsum asatshalaliswe ngokulinganayo ekubumbeni, athuthukise ubuntu nokufana komkhiqizo, futhi aqinisekise ukunemba okubucayi nomkhiqizo.

Ukusetshenziswa kwe-hydroxypropyllym methylcellulose (HPMC) ku-gypsum-based plaster kanye nemikhiqizo ye-gypsum inezinzuzo ezinkulu. Ngokwenza ngcono ukuqina, ukugcinwa kwamanzi, ukwakha amafilimu nezinye izakhiwo, i-HPMC ayigcini nje ngokuthuthukisa ukusebenza kwezokwakha kanye nekhwalithi yomkhiqizo eqediwe, kepha futhi inweba impilo yensiza yemikhiqizo ye-gypsum. Ecwaningweni nasekuthuthukisweni nasekusetshenzisweni kwezinto zokwakha, i-HPMC, njengesengezo esibalulekile esisebenzayo, sizoqhubeka nokudlala indima yayo ehlukile futhi senze iminikelo enkulu ekuthuthukisweni kwemboni yezokwakha.
