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

Magadzirirwo e "28-30% methoxyl" uye "7-12% hydroxypropyl" anoreva mwero wekutsiva muHydroxypropyl Methylcellulose(HPMC). Aya manhamba anoratidza kuti polymer yekutanga ye cellulose yakagadziriswa sei nemakemikari nemapoka e methoxyl ne hydroxypropyl.

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

Mwero wekutsiva une simba pahunhu hweHPMC uye mashandiro ayo mumashandisirwo akasiyana-siyana. Semuenzaniso:

• Kuwanda kwemethoxyl kunowanzoita kuti polymer isanyanye kunyungudika mumvura, zvichikanganisa kunyungudika kwayo mumvura nezvimwe zvinhu zvayo.
• Kuwanda kwehydroxypropyl kunogona kuwedzera kunyungudika kwemvura uye hunhu hweHPMC hwekugadzira firimu.

Magadzirirwo aya akakosha pakugadzirisa HPMC kuti ienderane nezvinodiwa mumaindasitiri akasiyana. Semuenzaniso, muindasitiri yemishonga, kusarudzwa kwegiredhi reHPMC rine madhigirii chaiwo ekutsiva kunogona kukanganisa marongero ekuburitswa kwemishonga mumapiritsi. Muindasitiri yekuvaka, zvinogona kukanganisa kuchengetedza mvura uye hunhu hwekunamatira kwezvigadzirwa zvakagadzirwa nesimende.

Vagadziri vanogadzira mhando dzakasiyana dzeHPMC dzine mwero wakasiyana wekutsiva kuti zvienderane nezvinodiwa zvakasiyana siyana zvemashandisirwo akasiyana. Pavanoshandisa HPMC mumafomura, zvakakosha kuti vanogadzira vafunge nezvemhando chaiyo yeHPMC inoenderana nezvinodiwa uye hunhu hwekushanda kwekushandisa kwacho.
