Hydroxypropyl methylcellulose, 28-30% methoxyl, 7-12% hydroxypropyl

Izvo zvinotsanangurwa "28-30% methoxyl" uye "7-12% hydroxypropyl" zvinoreva dhigirii rekutsiva mu.Hydroxypropyl methylcellulose(HPMC). Aya makoshero anoratidza mwero wekuti iyo yekutanga cellulose polymer yakagadziridzwa makemikari ne methoxyl uye hydroxypropyl mapoka.

1. 28-30% Methoxyl:
   • Izvi zvinoratidza kuti, paavhareji, 28-30% yemapoka ekutanga ehydroxyl pamorekuru we cellulose akatsiviwa nemapoka emethoxyl. Methoxyl mapoka (-OCH3) anounzwa kuti awedzere hydrophobicity yepolymer.
2. 7-12% Hydroxypropyl:
   • Izvi zvinoreva kuti, paavhareji, 7-12% yemapoka ekutanga ehydroxyl pamorekuru we cellulose akatsiviwa nemapoka ehydroxypropyl. Mapoka eHydroxypropyl (-OCH2CHOHCH3) anounzwa kuti awedzere kunyungudika kwemvura uye kugadzirisa zvimwe zvemuviri nemakemikari zvimiro zvepolymer.

Iyo dhigirii yekutsiva inopesvedzera zvimiro zveHPMC uye kuita kwayo mumashandisirwo akasiyana siyana. Semuyenzaniso:

• Yepamusoro methoxyl yemukati inowanzo wedzera iyo polymer's hydrophobicity, inokanganisa kunyungudika kwayo kwemvura uye zvimwe zvivakwa.
• Iyo yepamusoro hydroxypropyl yemukati inogona kuwedzera kunyungudika kwemvura uye firimu-kugadzira zvimiro zveHPMC.

Aya maratidziro akakosha mukugadzirisa HPMC kuti isangane nezvinodiwa mumaindasitiri akasiyana. Semuyenzaniso, muindasitiri yemishonga, kusarudzwa kwegiredhi reHPMC rine madhigirii chaiwo ekutsiva kunogona kukanganisa maprofile ekuburitswa kwemishonga mumagadzirirwo emapiritsi. Muindasitiri yekuvaka, inogona kukanganisa kuchengetedza kwemvura uye kunamatira zvivakwa zvesimende-based zvigadzirwa.

Vagadziri vanogadzira mamakisi akasiyana eHPMC ane madhigirii akasiyana ekutsiva kusangana nezvinodiwa zvakasiyana zvekushandisa kwakasiyana. Paunenge uchishandisa HPMC mukugadzira, zvakakosha kuti vagadziri vatarise giredhi chairo reHPMC rinoenderana nezvinodiwa uye maitiro ekuita kwechinodiwa chikumbiro.
