Indima ye-hydroxypropyl methylcellulose odakeni

I-Hydroxypropylmethylcellulose

Ngaphezu kwama-95% ebanga lokwakhai-hydroxypropyl methylcelluloseisetshenziswa ku-putty powder mortar. Imisebenzi yayo iwukuqina, ukugcinwa kwamanzi nokwakha. Ukusebenza kokugcinwa kwamanzi kwe-HPMC kuvimbela udaka ekuqhekekeni ngenxa yokoma ngokushesha ngemva kokufaka isicelo, kuthuthukisa amandla ngemva kokuqina, umsebenzi oyinhloko ukugcinwa kwamanzi, ukujiya, kanye nemiphumela yokulwa nokucwila. Ingasetshenziswa njenge-adhesive ku-plaster, i-gypsum, i-putty powder noma ezinye izinto zokwakha ukuze kuthuthukiswe ukusabalala nokwandisa isikhathi sokusebenza; njengamathayili e-ceramic, imabula, amapulasitiki Ukuhlobisa: Njengesithuthukisi sokunamathisela, kungase futhi kunciphise inani likasimende; ukuze uthole udaka lwe-anti-crack, engeza i-polypropylene anti-crack fiber (i-PP fiber) ngenani elifanele, ukuze ibe khona ngendlela yama-barbs odakeni, ukuze kuzuzwe umphumela wokulwa nokuqhekeka. I-HPMC idlala kuphela indima yokugcina amanzi, ukujiya kanye ne-anti-sag.

1. Udaka lokwakha ukhonkolo

Ukugcinwa kwamanzi aphezulu kungenza usimende ugcwale amanzi ngokugcwele, kwandise kakhulu amandla esibopho, futhi ngesikhathi esifanayo, kungakhuphula ngokufanele amandla okuqina namandla okugunda, kuthuthukise kakhulu umphumela wokwakha futhi kuthuthukise ukusebenza kahle komsebenzi.

2. I-putty engangeni manzi

Ku-putty, i-hydroxypropyl methylcellulose cellulose ether ngokuyinhloko idlala indima yokugcina amanzi, ukubopha kanye nokugcoba, ukugwema imifantu kanye nokuphelelwa amandla kwamanzi okubangelwa ukulahlekelwa kwamanzi amaningi, futhi ngesikhathi esifanayo kuthuthukise ukunamathela kwe-putty nokunciphisa i-sag ngesikhathi sokwakha I-Phenomenon, ukuze ukwakhiwa kube bushelelezi.

3. Uchungechunge lwe-plaster plaster

Phakathi kwemikhiqizo yochungechunge lwe-gypsum, i-hydroxypropyl methylcellulose cellulose ether ngokuyinhloko idlala indima yokugcina amanzi kanye nokugcoba, futhi ngesikhathi esifanayo inomphumela othize wokuhlehlisa, oxazulula izinkinga zokuqhekeka kwemigqomo nokuhluleka kokuqala kwamandla ngesikhathi sokwakhiwa, futhi inganwetshwa amahora okusebenza.

4. I-ejenti yesixhumi esibonakalayo

Ngokuyinhloko isetshenziswa njenge-thickener, engathuthukisa amandla aqinile namandla okugunda, ithuthukise ukumbozwa kwendawo, ithuthukise ukunamathela namandla okubopha.

5. Udaka lwangaphandle lokufakwa odongeni

Kulesi sihloko, i-hydroxypropyl methylcellulose cellulose ether idlala indima yokubopha nokwandisa amandla, okwenza kube lula ukumboza udaka nokuthuthukisa ukusebenza kahle komsebenzi. Khulisa isikhathi sokusebenza sodaka, uthuthukise ukushwabana nokumelana nokuqhekeka, uthuthukise ikhwalithi ephezulu, futhi ukhulise amandla ebhondi.

6. I-adhesive ye-tile

Ukugcinwa kwamanzi okuphezulu akudingi ukucwiliswa ngaphambili noma ukumanzisa amathayili nesisekelo, okungathuthukisa kakhulu amandla abo okubopha. I-slurry ingaba nesikhathi eside sokwakha, ilungile futhi iyunifomu, futhi ilungele ukwakhiwa. Futhi inokumelana okuhle nomswakama.

7, i-caulking agent, i-ejenti yokukhomba

Ukwengezwa kwei-hydroxypropyl methylcellulose cellulose etherkwenza kube nokubopha okuhle konqenqemeni, ukuncipha okuphansi nokumelana nokugqoka okuphezulu, okuvikela izinto eziyisisekelo ekulimaleni komshini futhi kugweme umonakalo obangelwa ukungena kuso sonke isakhiwo. Ithonya.
