Hydroxypropylmethylcellulose (HPMC) chinhu chinobva mu cellulose chinowanzoshandiswa mukugadzira zvinhu zvakasiyana-siyana, kusanganisira mvura yekugeza ndiro. Inoshanda sechinhu chinogodza zvinhu zvakasiyana-siyana, ichipa kusimba uye kugadzikana kwemafuta emvura.
Ongororo yeHPMC:
HPMC ipurasitiki yakagadzirwa ne cellulose, polymer yechisikigo inowanikwa mumadziro emasero emiti. Inogadzirwa nekushandisa cellulose inogadziriswa nemakemikari uchishandisa propylene oxide nemethyl chloride. Chigadzirwa chinobuda ipolymer inonyungudika mumvura ine hunhu hwakasiyana hwe rheological.
Basa reHPMC muzvinwiwa zvekusuka ndiro:
Kudzora Kusviba: Rimwe remabasa makuru eHPMC muzvinwiwa zvekusuka ndiro nderekudzora kusviba. Inopa mvura kugadzikana, ichivandudza magadzirirwo ayo ese uye kuyerera kwayo. Izvi zvakakosha kuti ive nechokwadi chekuti chinochenesa chinoramba chiri pamusoro uye chinobvisa mafuta netsvina zvinobudirira.
Kugadzikana: HPMC inovandudza kugadzikana kwekugadzirwa kwayo nekudzivirira kupatsanurwa kwechikamu uye kunaya kwemvura. Inobatsira kuchengetedza chigadzirwa chakafanana uye chakagadzikana nekufamba kwenguva, ichivimbisa kushanda kwakafanana.
Kuvandudzwa kwefuro: Pamusoro pekukora kwayo, HPMC inobatsirawo kuvandudza hunhu hwefuro hwezvinwiwa zvekusuka ndiro. Inobatsira kugadzira furo rakagadzikana rinobatsira mukuchenesa nekubata nekubvisa tsvina netsvina.
Kushanda nemasurfactants: Mvura yekugeza ndiro ine masurfactants, ayo akakosha pakupwanya mafuta. HPMC inoenderana nemasurfactants akasiyana-siyana, zvichiita kuti ive chinhu chakakodzera kukora maformula aya.
Kufunga Nezvezvakatipoteredza: HPMC inoonekwa seyakachengeteka pakuchengetedza nharaunda uye yakachengeteka kushandiswa muzvigadzirwa zvemumba. Inogona kuora uye haina njodzi huru kuhutano hwevanhu kana nharaunda.
Mashandisirwo uye mafomura:
HPMC inowanzo wedzerwa mumidziyo yekugeza ndiro panguva yekugadzira. Huwandu hweHPMC hunoshandiswa hunoenderana nekusimba kunodiwa uye zvimwe zvinodiwa zvechigadzirwa. Vagadziri vemagadzirirwo vanofunga nezvezvinhu zvakaita semhando yesurfactant uye huwandu hwayo, pH level, uye zvinangwa zvekushanda kwese.
Hydroxypropyl methylcellulose (HPMC) inoita basa rakakosha semuchina wekugocha ndiro, ichipa kudzora kusimba kweganda, kugadzikana uye furo riri nani. Inoenderana nemasurfactants uye hushamwari hwezvakatipoteredza zvinoita kuti ive sarudzo yakakurumbira mumhando dzezvishandiso zvekuchenesa imba.
