Lingakanani izinga lokusetshenziswa kwe-HPMC?

I-Hydroxypropyl methylcellulose (HPMC)iyi-ether ebalulekile ye-cellulose engeyona i-ionic esetshenziswa kabanzi ezimbonini ezahlukahlukene, okuhlanganisa ukwakhiwa, imithi, ukudla, kanye nezimonyo. Abantu abaningi bakhathazekile ngesilinganiso sokusetshenziswa kwe-HPMC. Kodwa-ke, umthamo awunqunyelwe; uyahlukahluka kuye ngemboni, uhlobo lomkhiqizo, izidingo zokusebenza, kanye nokwakheka.

1. Izinga Lokusetshenziswa kwe-HPMC Embonini Yokwakha

Imboni yokwakha ingenye yezindlela eziyinhloko zokusebenzisa i-HPMC, ikakhulukazi ku-dry-mix mortar, i-tile adhesive, i-putty powder, i-self-leveling mortar, kanye ne-thermal insulation mortar. I-HPMC isebenza ngokuyinhloko ukugcina amanzi, ukujiya, nokuthuthukisa ukusebenza kahle. Izinga lokusetshenziswa kwayo livame ukusuka ku-0.2% kuya ku-0.8%, kanje:

I-adhesive yethayela: Isilinganiso se-HPMC ngokuvamile siphakathi kuka-0.3% no-0.5%, silungiswa ngokusekelwe esilinganisweni sokumuncwa kwamanzi kwethayela, indawo yokwakha, kanye nezinga le-adhesive.

I-putty yodonga: Umthamo ojwayelekile u-0.2% kuya ku-0.4% ukuqinisekisa ubuso be-putty obubushelelezi, obungenamachaphaza. Udaka oluzilinganisayo: Umthamo uvame ukuba ngu-0.1% kuya ku-0.3%, futhi kudingeka ukulawulwa kwe-viscosity ukuze kulondolozwe ukugeleza.

Ukufakwa kodaka oluvikelayo: Umthamo we-HPMC ngokuvamile uphakathi kuka-0.3% kuya ku-0.6% ukuze kuthuthukiswe ukugcinwa kwamanzi nokunamathela, futhi kuvinjelwe ukugoba nokuqhekeka.

Izici ezithonya umthamo zifaka phakathi izinga le-viscosity le-HPMC (amazinga avamile afaka phakathi ama-mPa·s angu-40,000, ama-mPa·s angu-75,000, kanye nama-mPa·s angu-100,000), ukwakheka komkhiqizo, izinga lokushisa lokusetshenziswa, kanye nezakhiwo zesimende.

2. Ukusetshenziswa kwe-HPMC Embonini Yezemithi

Emkhakheni wezokwelapha, i-HPMC isetshenziswa kaningi njengento yokugqoka amaphilisi, ukwakheka okukhululwa njalo, kanye namagobolondo e-capsule, kodwa idinga ubumsulwa obukhulu kakhulu kanye nokuphepha. Ukusetshenziswa Okuvamile:

Ukwembozwa kwethebhulethi: Ngokuvamile u-2% kuya ku-5% wesisindo sethebhulethi usetshenziselwa ukulawula izinga lokuncibilika nokuthuthukisa ukubukeka.

Amaphilisi okukhululwa okuqhubekayo: Okuqukethwe kwe-HPMC kungafinyelela ku-10% kuya ku-40%, okusebenza njengezinto ezibonakalayo zokubambezela ukukhishwa kwemithi. Amaphilisi angenalutho: I-HPMC cishe iyisithako esiyinhloko kumaphilisi, esingaphezu kuka-50%.

3. Ukusetshenziswa kwe-HPMC Embonini Yokudla

I-HPMC isetshenziswa njengesithambisi, i-emulsifier, kanye nesiqinisi ekudleni, futhi ivame ukusetshenziswa ezinhlotsheni ezibhakiwe, eziphuzweni, kanye nemikhiqizo yobisi enamafutha aphansi. Amanani okusetshenziswa ngokuvamile asukela ku-0.1% kuya ku-0.5%. Isibonelo:

I-ayisikhilimu: Cishe u-0.2% wengezwe ukuthuthukisa ukunambitheka nokuvimbela ukwakheka kwekristalu yeqhwa.

Izimpahla ezibhakiwe: Cishe u-0.3% wengezwe ukuze kuthuthukiswe ukugcinwa komswakama kanye nokuthamba.

4. Ukusetshenziswa kwe-HPMC Embonini Yamakhemikhali Yansuku Zonke

I-HPMC isetshenziswa njengesithako esijiyisayo kanye nesithako esithambile kuma-shampoo, ama-shower gels, kanye nemikhiqizo yokunakekelwa kwesikhumba, ngokuvamile ngesilinganiso sokusetshenziswa esingu-0.3% kuya ku-1.0%. Phakathi kwalokhu:

I-shampoo: 0.3% kuya ku-0.6% engeziwe ukuze kuthuthukiswe izakhiwo ze-rheological kanye nomuzwa.

Ama-lotion okunakekela isikhumba: Cishe angu-0.5% kuya ku-1.0% anezelwe ukuthuthukisa ukusabalala nokwakha ifilimu yokuthambisa isikhumba.

5. Izici Eziyinhloko Ezithinta Izinga Lokusetshenziswa Kwe-HPMC

Uhlobo Lomkhiqizo: Izinhlelo ezahlukene zinezidingo ezahlukene, isib., udoti > ukudla.

Ukujiya kwe-HPMC: Ukujiya okuphezulu kwe-HPMC idinga umthamo ophansi kakhulu, kodwa ibonisa ukugcinwa kwamanzi okuphezulu.

Izinga Lokushisa Nemvelo: Ukusetshenziswa kwezinga lokushisa eliphezulu kudinga ukugcinwa kwamanzi okuphezulu, okwandisa ukusetshenziswa kwe-HPMC.

Ukuhlanganiswa Kwezinto Ezintsha: Ukusetshenziswa kwe-HPMC kungancishiswa uma i-RDP noma i-starch ether isetshenziswa njengesithasiselo.

Ayikho indinganiso eqinile yokusetshenziswa kwe-HPMC; kumele ihambisane nezidingo ezithile zemboni kanye nokwakheka. Ngokuvamile, izinga lokusetshenziswa embonini yokwakha lingu-0.2%-0.6%, embonini yezemithi lingafinyelela ku-40%, embonini yokudla cishe lingu-0.1%-0.5%, kanti emikhiqizweni yamakhemikhali yansuku zonke ingu-0.3%-1.0%.Ukukhetha uhlobo olufanele lwe-HPMCkanye nomthamo akugcini nje ngokuthuthukisa ukusebenza komkhiqizo kodwa futhi kulawula nezindleko ngempumelelo.
