Hydroxypropyl methylcellulose (HPMC) is nonionic cellulose ether inoshandiswa zvakanyanya mumhando dzakasiyana dzemaindasitiri nemishonga. Mabasa ayo makuru anosanganisira thickener, firimu rekare, stabilizer, emulsifier, kumisa mumiririri uye anonamira. HPMC inoshandiswa zvakanyanya mumishonga, cosmetic, chikafu, zvekuvaka uye mamwe maindasitiri. Kushandiswa kwayo kunoenderana neiyo chaiyo ndima yekushandisa, inodiwa inoshanda mhedzisiro, zvimwe zvinongedzo zvekugadzira uye zvakatemwa zvekutonga zvinodiwa.
1. Pharmaceutical field
Mukugadzirira kwemishonga, HPMC inowanzoshandiswa seyakagadziriswa-yakaburitswa mumiriri, yekuputira zvinhu, firimu rekare uye capsule chikamu. Mumahwendefa, kushandiswa kweHPMC kunowanzova pakati pe2% ne5% yehuremu hwese kudzora kuburitswa kwemushonga. Kune mahwendefa anoramba achiburitswa, kushandiswa kungave kwakakwira, kunyangwe kusvika ku20% kana kupfuura, kuve nechokwadi chekuti mushonga unogona kuburitswa zvishoma nezvishoma kwenguva yakareba. Sechinhu chekuputira, kushandiswa kweHPMC kunowanzo kuve pakati pe3% ne8%, zvichienderana nehukobvu hunodiwa hwekujasa uye zvinoshanda zvinodiwa.
2. Indasitiri yezvokudya
Muindasitiri yezvekudya, HPMC inowanzoshandiswa seyakakora, emulsifier, suspending agent, etc. Inoshandiswa sechinhu chinotsiva mafuta muzvokudya zvakaderera-calori nokuti inogona kupa kuravira kwemafuta uye chimiro. Mari inoshandiswa mukudya inowanzova pakati pe0.5% ne3%, zvichienderana nerudzi uye kuumbwa kwechigadzirwa. Semuenzaniso, muzvinwiwa, sosi kana zvigadzirwa zvemukaka, huwandu hweHPMC hunoshandiswa kazhinji hushoma, hunenge 0.1% kusvika 1%. Mune zvimwe zvekudya zvinoda kuwedzera viscosity kana kuvandudza magadzirirwo, senge ma noodles ekare kana zvigadzirwa zvakabikwa, huwandu hweHPMC hunoshandiswa hunogona kunge hwakakwira, kazhinji pakati pe1% ne3%.
3. Cosmetic Field
Muzvizoro, HPMC inoshandiswa zvakanyanya seyakakora, stabilizer uye firimu rekare mune lotions, makirimu, shampoos, mimvuri yeziso uye zvimwe zvigadzirwa. Chiyero chayo chinowanzo 0.1% kusvika 2%, zvichienderana nezvinodiwa viscosity yechigadzirwa uye hunhu hwezvimwe zvinongedzo. Mune zvimwe zvekuzora, senge zvigadzirwa zvekuchengetedza ganda kana sunscreens inoda kuumba firimu, huwandu hweHPMC hunoshandiswa hunogona kunge hwakakwirira kuve nechokwadi chekuti chigadzirwa chinoumba yunifomu yekudzivirira paganda.
4. Zvinhu zvekuvaka
Muzvivakwa zvekuvaka, HPMC inoshandiswa zvakanyanya muzvigadzirwa zvakaita sesimende, zvigadzirwa zvegypsum, pendi yelatex uye zvinonamira mataira kuvandudza kuita kwekuvaka kwezvinhu, kuwedzera nguva yakavhurika, nekuvandudza anti-sagging uye anti-kuparuka zvivakwa. Huwandu hweHPMC hunoshandiswa muzvivakwa zvekuvaka hunowanzo pakati pe0.1% ne1%, zvichienderana nezvinodiwa zvekuumbwa. Zvesimende dhaka kana gypsum zvinhu, huwandu hweHPMC hunowanzo 0.2% kusvika 0.5% kuona kuti zvinhu zvacho zvine kuita kwakanaka kwekuvaka uye rheology. Mune latex pendi, huwandu hweHPMC hunowanzo 0.3% kusvika 1%.
5. Mitemo nemitemo
Nyika dzakasiyana uye matunhu ane mirau yakasiyana uye zviyero zvekushandiswa kweHPMC. Mumunda wezvekudya nemishonga, kushandiswa kweHPMC kunofanirwa kuenderana nezvinopihwa nemirairo yakakodzera. Semuenzaniso, muEU nekuUnited States, HPMC inozivikanwa zvakanyanya seyakachengeteka (GRAS), asi kushandiswa kwayo kuchiri kufanira kudzorwa zvichienderana nemhando yezvigadzirwa uye mashandisirwo. Muminda yekuvaka uye zvizorwa, kunyangwe kushandiswa kweHPMC kusiri pasi pezvirambidzo zvakanangana nemirairo, kukanganisa kunogona kuitika kune nharaunda, kuchengetedzwa kwechigadzirwa uye hutano hwevatengi huchiri kufanira kutariswa.
Iko hakuna yakagadziriswa chiyero chehuwandu hweHPMC inoshandiswa. Iyo inotsamira zvakanyanya pane chaiyo application mamiriro, inodiwa inoshanda mhedzisiro, uye kurongeka kwezvimwe zvinongedzo zvekugadzira. Kazhinji, huwandu hweHPMC hunoshandiswa hunobva pa0.1% kusvika 20%, uye kukosha chaiko kunoda kugadziridzwa zvinoenderana nekugadzira dhizaini uye zvinodiwa zvekutonga. Mumashandisirwo chaiwo, vashandi veR&D vanowanzogadzirisa zvinoenderana nedata rekuyedza uye ruzivo kuti vakwanise kushandisa zvakanakisa maitiro uye mutengo-unoshanda. Panguva imwecheteyo, kushandiswa kweHPMC kunofanirwa kuenderana neakakodzera indasitiri zviyero nemirau kuti ive nechokwadi chekuchengetedza uye kutevedza kwechigadzirwa.
