Iqhaza le-hydroxypropyllll methylcellulose kudaka

Hydroxypropylmethylcellellulose

Bangaphezu kuka-95% wezokwakha-gratch hydroxypropyll methylcellulose asetshenziswa ku-putty powder wodun. Imisebenzi yayo iyaqina, ukugcinwa kwamanzi nokwakha. Ukusebenza kokugcinwa kwamanzi kwe-HPMC kuvimbela ama-slurry kusuka ekuqhekekeni ngenxa yokomisa ngokushesha okukhulu ngemuva kwesicelo, ukuthuthukisa amandla ngemuva kokukhula kwamanzi, ukuqina, kanye nemiphumela yokulwa nokulwa. Ingasetshenziswa njengombala onamathela ku-plaster, i-gypsum, i-putty powder noma ezinye izinto zokwakha ukuthuthukisa ukusakazeka kanye nesikhathi esandisa ukusebenza; njengamathayili e-ceramic, umhlobiso wemabula, amapulasitiki: njengesithuthukisi sokunamathisela, kunganciphisa futhi inani likasimende; Ngohlobo lokulwa nokulwa, engeza i-polypropylene anti-crack fiber (i-PP fiber) ngenani elifanele, ukuze abe khona ngesimo sebharibs ku-datar, ukuze afeze umphumela wokulwa nokulwa. I-HPMC imane idlala indima yokugcinwa kwamanzi, ukuqina kanye ne-anti-sag.

1. Udaka lodaka lokwakha udaka

Ukugcinwa kwamanzi okuphezulu kungenza usimende ophelelwe yi-hydrate ngokuphelele, wandise kakhulu amandla webhondi, futhi ngasikhathi sinye, kungakhulisa amandla ashubile namandla okugunda, ukuthuthukisa kakhulu ukusebenza komsebenzi kanye nokwenza ngcono umsebenzi.

2. I-putty engamelana namanzi

Ku-putty, hydroxypropyl methylcellose cellulose ether ikakhulukazi kudlala indima yokugcinwa kwamanzi, futhi ngasikhathi sinye okubangelwa ukulahleka kwamanzi ngesikhathi se-punomenon, ukuze ukwakhiwa kubushelelezi.

Phakathi kwemikhiqizo ye-gypsum yochungechunge, i-hydroxypropyll methylcellosise cellulose ether ikakhulukazi idlala indima yokugcinwa kwamanzi nokuthambisa okukodwa, futhi ngasikhathi sinye ukwehluleka kwe-Drum Creaming kanye nokwehluleka kwamandla okuqala ngesikhathi sokwakha, futhi kunganwetshwa amahora okusebenza

4. I-ejenti ebonakalayo

Isetshenziswa kakhulu njengomuntu omkhulu, ongathuthukisa amandla ashukumisayo namandla okugunda, athuthukise ukunamathela komhlaba, athuthukise ukunamathela namandla obopho.

5. Udaka lwangaphandle oludongeni olungaphandle

Kulokhu okubonakalayo, i-hydroxypropyl methylcellose cellulose ether ikakhulukazi idlala indima yokubopha futhi ikhulise amandla, okwenza kube lula ukumboza udaka nokwenza ngcono umsebenzi kahle. Khulisa isikhathi sokusebenza sodaka, uthuthukise i-shrinkage kanye nokumelana nokuqhekeka, uthuthukise ikhwalithi ephezulu, futhi ukhuphule amandla e-bond.

6. Ithayili elinamathelayo

Ukugcinwa kwamanzi okuphezulu akudingi ukucwilisa noma kumanzi amathayili kanye nesisekelo, esingathuthukisa amandla amakhulu abo. I-slurry ingaba nesikhathi eside sokwakhiwa, ilungile futhi iyunifomu, futhi ilungele ukwakhiwa. Futhi inokumelana kahle nomswakama.

7, i-ejenti ye-caulking, umenzeli okhomba

Ukungezwa kwe-hydroxypropylllypropyl methyllellulose cellulose ether kwenza kube nokubopha okuhle, ukumelana okuphansi kanye nokumelana okuphezulu, okuvikela ukulimala okubangelwa ukungeniswa kwayo sonke isakhiwo. Ithonya.
