IHydroxypropyl methylcellulose yokufafaza odongeni!

Imikhiqizo ye-Hydroxypropyl methylcellulose yokwakha isetshenziswa kabanzi ukuthuthukisa ukusebenza kwezinto zokwakha ezinama-hydraulic, njengosimende negypsum.Ezisimendeni ezenziwe usimende, zenza ngcono ukugcinwa kwamanzi, andise ukulungiswa kanye nezikhathi ezivulekile, futhi kunciphisa ukuwohloka.

a.Ukugcinwa kwamanzi

IHydroxypropyl methylcellulose yokwakha ivimbela umswakama ukuthi ungangeni odongeni.Inani elifanele lamanzi lihlala odakeni, ukuze usimende ube nesikhathi eside sokukhipha amanzi.Ukugcinwa kwamanzi kuhambisana ne-viscosity yesisombululo se-cellulose ether esisetsheni.Ukuphakama kwe-viscosity, kungcono ukugcina amanzi.Lapho ama-molecule amanzi anda, ukugcinwa kwamanzi kuncipha.Ngoba ngenani elifanayo lesisombululo se-hydroxypropyl methylcellulose esiqondene nokwakhiwa, ukwanda kwamanzi kusho ukuncipha kwe-viscosity.Ukwenziwa ngcono kokugcinwa kwamanzi kuzoholela ekwandiseni isikhathi sokulungisa udaka olwakhiwayo.

b.Thuthukisa ukwakhiwa

Ukusetshenziswa kwe-hydroxypropyl methylcellulose HPMC kungathuthukisa ukwakhiwa kodaka.

c.Ikhono lokugcoba

Wonke ama-ejenti afaka umoya-mpilo asebenza njengama-ejenti wokumanzisa ngokwehlisa ukushuba kwendawo futhi asize izinhlawulo ezisesimendeni ukuba zihlakazeke lapho zixutshwe namanzi.

d.I-Anti-sagging

Udaka oluhle olungancibiliki lusho ukuthi uma lusetshenziswa ezingqimbeni eziwugqinsi ayikho ingozi yokucwila noma ukugeleza okuya phansi.Ukumelana ne-Sag kungathuthukiswa ngokwakhiwa okuqondile kwe-hydroxypropyl methylcellulose.I-hydroxypropyl methylcellulose eqondene nokwakha ekhiqizwe yi-Shandong Chuangyao Company ingahlinzeka ngezakhiwo ezingcono zokulwa nokusagiga kodaka.

e.Okuqukethwe kwebhamuza

Okuqukethwe kwebhamuza lomoya okuphezulu kubangela isivuno esingcono sodaka nokusebenza, kunciphisa ukwakheka kokuqhekeka.Iphinde yehlise inani lokuqina, ibangele "i-liquefaction" into.Okuqukethwe kwebhamuza lomoya ngokuvamile kuncike esikhathini sokunyakazisa.

Izinzuzo ze-hydroxypropyl methylcellulose ekwakhiweni kwezinto zokwakha:

IHydroxypropyl methylcellulose inezinto zayo eziyingqayizivele ekusetshenzisweni kwezinto zokwakha, kusukela ekuxubeni kuya ekuhlakazweni kuya ekwakheni, kanje:

Inhlanganisela nokumisa:

1. Kulula ukuxuba nefomula yempushana eyomile.

2. Inezici zokuhlakazeka kwamanzi abandayo.

3. Misa izinhlayiya eziqinile ngokuphumelelayo, okwenza ingxube ibe bushelelezi futhi ifane.

Ukuhlakazeka nokuxuba:

1. Ifomula yenhlanganisela eyomile equkethe i-hydroxypropyl methylcellulose ingaxutshwa kalula namanzi.

2. Thola ngokushesha ukuvumelana okufunayo.

3. Ukuqedwa kwe-cellulose ether kuyashesha futhi ngaphandle kwezigaxa.

Ukwakhiwa ku-inthanethi:

1. Thuthukisa i-lubricity ne-plasticity ukuze uthuthukise ukusebenza kahle futhi wenze ukwakhiwa komkhiqizo kube lula futhi kusheshe.

2. Thuthukisa izici zokugcina amanzi futhi welule isikhathi sokusebenza.

3. Isiza ukuvimbela ukugeleza okuqondile kodaka, udaka namathayili.Yelula isikhathi sokupholisa futhi uthuthukise ukusebenza kahle komsebenzi.

Ukusebenza nokubukeka okuqediwe:

1. Thuthukisa amandla okubopha ama-adhesive tile.

2. Thuthukisa i-anti-crack shrinkage namandla okulwa nokuqhekeka kodaka nesigcwalisi esihlanganyelwe sebhodi.

3. Thuthukisa okuqukethwe komoya odakeni futhi unciphise kakhulu amathuba okuqhekeka.

4. Thuthukisa ukubukeka kwemikhiqizo eqediwe.

5. Ingathuthukisa ukumelana nokugeleza okuqondile kwama-adhesive tile.

I-Hydroxypropyl methylcellulose (HPMC) iyi-ether ye-cellulose engeyona i-ionic eyenziwe kusuka ukotini omsulwa ngochungechunge lwezinqubo zamakhemikhali.IHydroxypropylmethylcellulose (HPMC) iyimpushana emhlophe engenaphunga, engenabuthi engancibilika emanzini abandayo ukuze yakhe isixazululo se-viscous esisobala.Inezici zokuqina, ukubopha, ukusabalalisa, i-emulsifying, ifilimu-forming, ukumisa okwesikhashana, i-adsorbing, i-gelling, i-surface esebenzayo, ukugcina umswakama nokuvikela i-colloid.
