Hydroxypropyl Methyl Cellulose (HPMC) kuKwakha– IiNkcazo zeMveliso

Uhlobo loMzimba kunye neNkangeleko

I-HPMC ibonakala ngathi imhlophe okanye i-beige, umgubo okhululekileyo. Ayinayo ivumba elibonakalayo kwaye iyancibilika ngokufanelekileyo emanzini abandayo ukwenza icace, ukhetho olungqingqwa. Umgubo uhlala uzinzile phantsi kweemeko eziqhelekileyo zendawo yogcino kwaye awubhobhozi xa ugcinwe womile.

Viscosity ezahlukeneyo
I-Viscosity luphawu lokusebenza oluphambili lwe-HPMC kwizicelo zokwakha nokwakha. Iimpawu eziqhelekileyo zibonelela ngezidanga ukusuka 400 mPa · s ukuya 100,000 mPa · s, ilinganiswe kwi 2% ugxininiso kunye 20 °C. Iimpawu zokwakha eziqhelekileyo ziwela phakathi 4,000 mPa · s kunye 75,000 mPa · s, kuxhomekeke kusetyenziso oluthile– njengezinto zokuncamathelisa iithayile, inikeza, okanye i-self-leveling compounds.

Izidanga zoTshintsho
HPMC iqulathe 2 amaqela eether eziphambili: i-methoxy kunye ne-hydroxypropoxy. Umxholo oqhelekileyo we-methoxy usukela 19% ukuya 30%, ngelixa umxholo we-hydroxypropoxy uqhelekile phakathi 4% kwaye 12%. Ezi zidanga zinefuthe elithe ngqo kugcino lwamanzi, ukusebenza, kunye nokumisela ixesha kwiimveliso ezisekwe kwisamente.

Ukugcinwa kwamanzi
Ugcino lwamanzi oluphezulu lubalulekile ukuze kufakwe isamente ngokufanelekileyo. I-HPMC esetyenziswa kulwakhiwo idla ngokugcina ngaphezulu 90% yokuxuba amanzi kwiimviwo zodaka eziqhelekileyo (umz., emva 20 imiz kwiphepha lokucoca). Oku kuqinisekisa ukuphiliswa rhoqo kwaye kunciphisa ukwaphuka okanye ukubola.

Ubunyulu noKhuseleko
Imveliso iyanelisa imigangatho yehlabathi yee-ethers ze-cellulose zodidi lolwakhiwo. Ayinazinto zendalo ezingazinzanga (IiVOCs) kwaye ayinayo ityhefu. Umxholo we-Ash uhlala udweliswe ngezantsi 5%, kunye ne-pH ye 2% inkonzo ihlala phakathi 6.0 kwaye 8.5.

Ukupakishwa kwemveliso kunye nendawo yokuGcina
I-HPMC igxininiswe kwiingxowa ezininzi zephepha ezine-polyethylene yangaphakathi, ngokwesiqhelo kwi 25 kg izixhobo. Thenga kwindawo entle, indawo eyomileyo ngokupheleleyo kude nobumanzi. Gcina izikhongozeli zikhuselekile xa zingasetyenziselwa ukumisa i-caking okanye ilahleko yokusebenza kakuhle.
