Hydroxypropyl methylcellulose, inozivikanwawo se hypromellose uye cellulose hydroxypropyl methyl ether, inogadzirwa ne cotton cellulose yakachena kwazvo uye inonyanya kupiswa kana paine alkaline.
musiyano:
hunhu hwakasiyana
Hydroxypropyl methylcellulose: upfu kana granules zvakaita sefiber chena kana chena, zviri mumhando dzakasiyana dzemhando dzisiri dzeionic mumusanganiswa wecellulose, chigadzirwa ichi ipolymer yeviscoelastic isingashande, isingashande.
Hydroxyethyl cellulose ifayibha chena kana yero, isina hwema, isina chepfu kana upfu hwakasimba, chinhu chikuru chakagadzirwa ialkali cellulose uye ethylene oxide etherification, inova iyo non-ionic soluble cellulose ether.
Kushandiswa kwakasiyana
Muindasitiri yekupenda, hydroxypropyl methylcellulose inonyungudika zvakanaka mumvura kana mune zvinonyungudutsa zvakasikwa semuchina wekuomesa, wekuparadzanisa uye wekusimbisa. Polyvinyl chloride inoshandiswa semushonga wekubvisa pendi pakugadzira polymerization yepurasitiki, iyo inoshandiswa zvakanyanya mumatehwe, zvigadzirwa zvemapepa, kuchengetedza michero nemiriwo, machira nedzimwe nzvimbo.
Hydroxypropyl methylcellulose: hainyungudike zvachose mune ethanol, ether, acetone; inonyungudika mumvura inotonhora kana kuti ine turbid colloidal solution, inoshandiswa zvakanyanya mukuputira, inki, fibers, dhayi, kugadzira mapepa, zvizoro, mishonga yezvipembenene, zvicherwa. Kugadzirisa zvigadzirwa, kudzoreredza mafuta uye maindasitiri emishonga.
kunyunguduka kwakasiyana
Hydroxypropyl methylcellulose: hainyungudike zvachose muethanol, ether, acetone; inonyungudika mumvura inotonhora kana kuti ine makore mashoma.
Hydroxyethyl cellulose (HEC): Inogona kugadzira mhinduro dzakasiyana-siyana, uye ine hunhu hwakanaka hwekunyungudutsa munyu kune ma electrolytes.
