I-HPMC esetshenziswa ekwakheni

I-HPMC Hydroxypropyl methyl cellulose, eyaziwa nangokuthi i-hydroxypropyl methyl cellulose ether (HPMC), i-cellulose hydroxypropyl methyl ether, ukukhethwa kwe-cellulose kakotini ecwenge kakhulu njengempahla eluhlaza, ngaphansi kwezimo ze-alkali ngokufaka i-etherification ekhethekile nokulungiswa.

I-Hydroxypropyl methyl cellulose HPMC esetshenziselwa ukwakhiwa, inani le-cellulose ether eyengeziwe liphansi kakhulu, kodwa lingathuthukisa kakhulu ukusebenza kodaka olumanzi, ukusebenza kokwakhiwa kodaka kuyisengezo esikhulu. Manje, i-hydroxypropyl methyl cellulose esetshenziswa ku-dry mortar cellulose ether ikakhulukazi i-hydroxypropyl methyl cellulose ether (HPMC). I-Hydroxypropyl methyl cellulose ekwakheni udaka olomile I-HPMC idlala indima enkulu ekugcineni amanzi, ukuqina, ukuthuthukisa ukusebenza kokwakhiwa.

1, udaka lokwakha ukhonkolo

Ukugcinwa kwamanzi okuphezulu kungenza usimende ugcwale amanzi ngokugcwele, kukhuphule ngokuphawulekayo amandla ebhondi, futhi kungathuthukisa ngokufanelekile amandla okuqina namandla okugunda, kuthuthukise kakhulu umphumela wokwakha, kuthuthukise ukusebenza kahle komsebenzi.

I-2, i-putty yokumelana namanzi

Ku-putty HPMC i-hydroxypropyl methyl cellulose ether idlala indima enkulu yokugcina amanzi, ukubopha kanye nokugcobisa, ukugwema ukwenzeka kokuqhekeka nokuphelelwa amandla kwamanzi okubangelwa ukulahleka kwamanzi ngokushesha kakhulu, futhi kuthuthukise ukunamathela kwe-putty, kunciphisa ukwenzeka kokugeleza okulenga ngaphakathi. ukwakhiwa, ukuze ukwakhiwa kube bushelelezi.

3, upende we-gypsum series

Ku-gypsum uchungechunge lwemikhiqizo ye-HPMC hydroxypropyl methyl cellulose ether ikakhulukazi ukudlala ukugcinwa kwamanzi, ukwandisa ukugcotshwa kanye neminye imiphumela, ngesikhathi esifanayo kunomphumela wokulibaziseka othize, ukuxazulula inqubo yokwakha ukuqhekeka kwesigubhu, amandla okuqala awekho enkingeni, angandisa isikhathi eside. isikhathi sokusebenza.

4, i-ejenti yokuxhumana

Isetshenziswa kakhulu njenge-thickener, ingathuthukisa amandla aqinile namandla okugunda, ithuthukise ukunamathela kwendawo, ithuthukise ukunamathela namandla okubopha.

5, udaka lwangaphandle lokufakelwa

I-HPMC Hydroxypropyl methyl cellulose, i-cellulose ether ekugxilweni kwezinto ezibonakalayo ekubopheni, ukwandisa amandla, ukwenza kube lula ukuhlanganisa udaka, ukuthuthukisa ukusebenza kahle komsebenzi, ngesikhathi esifanayo ukumelana nokugeleza okuqondile, ukusebenza okuphezulu kokugcinwa kwamanzi kungandisa isikhathi sokusebenza kodaka, thuthukisa ukuncipha kanye nokumelana nokukhathala okushisayo, uthuthukise ikhwalithi ephezulu, uthuthukise amandla okubopha.

6, i-ceramic tile binder

Ukugcinwa kwamanzi aphezulu akukwazi ukucwilisa ngaphambili noma kumanzi amathayili e-ceramic kanye nesisekelo, kuthuthukise kakhulu amandla ayo esibopho, i-slurry ingaba umjikelezo omude wokwakha, uthambile, umfaniswano, ukwakhiwa okulula, futhi unokumelana okuhle nomswakama.

7, i-ejenti yokugcwalisa umphetho, i-ejenti yokuhlanganisa

Ukwengezwa kwe-hydroxypropyl methyl cellulose HPMC cellulose ether kuyenza ibe nokunamathela okuhle konqenqemeni, ukuncipha okuphansi nokumelana nokugqoka okuphezulu, ukuvikela izinto eziyisisekelo ekulimaleni komshini, ukugwema umthelela wokungenwa kuwo wonke isakhiwo.

8, self leveling impahla

Isibopho esizinzile se-Hydroxypropyl methyl cellulose cellulose ether ukuze kuqinisekiswe uketshezi oluhle kanye nekhono lokuzilinganisa, lawula izinga lokugcinwa kwamanzi ukuze liqine ngokushesha, linciphise ukuqhekeka nokufinyela.

9. Upende we-latex

IHydroxypropyl methyl cellulose embonini yokumboza i-cellulose ether njengefilimu-yangaphambili, i-ejenti ejiyayo, i-emulsifier nesiqinisi esetshenziswa, ikwenze ibe nokungalunywa kahle kwe-abrasion, ukunamathela, ukunamathela, ukuthuthukisa ikhwalithi yevelu ye-PH ye-top tension, kanye nomphumela wengxube ye-solvent ye-organic. kungcono futhi, ukusebenza kwe-Gao Baoshui kuyenza ibe nempahla yokuxubha nokugeleza okuhle.

10. Izitsha zobumba lezinyosi

Kumaceramics amasha ekhekheba lezinyosi, i-billet inikezwa ukuthambisa, ukugcinwa kwamanzi kanye nokuthuthukiswa kwamandla.

Imikhiqizo yochungechunge oluhle kakhulu lwe-hydroxypropyl methyl cellulose ingaxazulula ngempumelelo inkinga yokugcinwa kwamanzi ngaphansi kwezinga lokushisa eliphezulu. Esikhathini sokushisa okuphezulu, ikakhulukazi ezindaweni ezishisayo nezomile kanye nokwakhiwa kongqimba oluncane ohlangothini olushisayo, i-HPMC yekhwalithi ephezulu iyadingeka ukuze kuthuthukiswe ukugcinwa kwamanzi odaka. Ikhwalithi ephezulu ye-HPMC, ukufana kuhle kakhulu, amaqembu ayo e-methoxy kanye ne-hydroxypropyl eduze nokusabalalisa iyunifomu yamangqamuzana e-cellulose, ingathuthukisa isibopho se-hydroxyl ne-ether kuma-athomu omoya-mpilo kanye nekhono le-hydrogen bond lenhlangano yamanzi, lenze amanzi amahhala abe amanzi ahlangene, ukuze ngokuphumelelayo lawula ukuhwamuka kwamanzi okubangelwa izinga lokushisa eliphezulu, ukufeza ukugcinwa kwamanzi aphezulu.

Ikhwalithi ephezulu ye-hydroxypropyl methyl cellulose ingahlakaza ngokulinganayo nangempumelelo odakeni lukasimende nemikhiqizo kasimende, futhi ipakishe zonke izinhlayiya eziqinile, futhi yakhe ungqimba lwefilimu yokumanzisa, umswakama osesisekelweni isikhathi eside ukhululwa kancane kancane, kanye nokusabela kwe-hydration yezinto ezingaphili zikasimende. , ukuze kuqinisekiswe amandla esibopho namandla acindezelayo wezinto zokwakha. Ngakho-ke, ekushiseni okuphezulu ekwakhiweni kwehlobo, ukuze kuzuzwe umphumela wokongiwa kwamanzi, ngokusho kwefomula yokwengeza imikhiqizo yekhwalithi ephezulu ye-HPMC, ngaphandle kwalokho, kuzoba nokoma ngokushesha okubangelwa ukungondleki okwanele, ukunciphisa amandla, ukuqhekeka, isigubhu esingenalutho kanye ukuwa kanye nezinye izinkinga izinga, kodwa futhi ukwandisa nobunzima abasebenzi ukwakhiwa. Njengoba izinga lokushisa lincipha, inani le-HPMC lingancishiswa kancane kancane, futhi umphumela ofanayo wokugcina amanzi ungafinyelelwa.
