HPMC, zita rakazara ndiHydroxypropyl Methylcellulose, isiri-ionic cellulose ether inoshandiswa zvakanyanya mukuvaka, mushonga, chikafu, makemikari ezuva nezuva nemimwe minda.
1. Kurongwa ne viscosity
Iyo viscosity yeHPMC ndeimwe yezvinhu zvayo zvakakosha zvemuviri, uye HPMC ine viscosity yakasiyana ine misiyano yakakura mukushandiswa. Iro viscosity range kubva kune yakaderera viscosity (makumi ecps) kusvika kune yakakwirira viscosity (makumi ezviuru zvecps).
Low viscosity HPMC: Inowanzo shandiswa muzvishandiso zvinoda kukurumidza kunyungudika kana kuyerera, senge mvura inomiswa mishonga yemishonga, sprays, nezvimwe.
Medium viscosity HPMC: inoshandiswa zvakanyanya mumakemikari ezuva nezuva, senge shampoo, gel yekugeza, nezvimwewo, ichipa zvine mwero thickening maitiro uye yakanaka rheological properties.
Yakakwira viscosity HPMC: inonyanya kushandiswa mukuvaka zvinhu, senge yakaoma dhaka, ceramic tile inonamira, yemukati uye yekunze madziro putty, nezvimwewo, ichipa yakanakisa kukora, kuchengetedza mvura uye zvivakwa zvekuvaka.
2. Kurongwa nechiyero chekutsiva
Iyo dhigirii yekutsiva yeHPMC inoreva huwandu hwehydroxypropyl uye methyl inotsiva mumorekuru wayo, inowanzo ratidzwa seMS (hydroxypropyl degree of substitution) uye DS (methyl substitution).
Yakaderera dhigirii yekutsiva HPMC: inonyungudika nekukurumidza uye inonyanya kushandiswa mumaapplication anoda kukurumidza kunyungudika, senge mishonga yekuputira piritsi uye zvinwiwa ipapo.
High degree of substitution HPMC: Iine viscosity yepamusoro uye kuchengetedzwa kwemvura zviri nani, uye inokodzera zvigadzirwa zvinoda high viscosity uye kuchengetwa kwemvura yakakwirira, senge zvinhu zvekuvaka uye zvinonyanya kushanda zvinonyorovesa zvizoro.
3. Kurongwa nenzvimbo dzekushandisa
Iwo chaiwo mashandisirwo eHPMC muminda dzakasiyana anosiyana zvakanyanya, uye anogona kupatsanurwa muzvikamu zvinotevera zvinoenderana neminda yekushandisa:
zvokuvakisa
Basa guru reHPMC mundima yekuvaka nderekuvandudza mashandiro ekuvaka uye kusimba kwezvinhu, zvinosanganisira:
Dry motar: HPMC inopa kuchengetwa kwemvura kwakanaka, lubricity uye kushanda, kuvandudza kushanda kwekuvaka uye kupera kwechigadzirwa.
Tile adhesive: Wedzera simba rekubatanidza uye anti-slip zvivakwa kuti ive nechokwadi chekugadzikana uye kusimba kweiyo tile paving.
Paint uye putty: Wedzera rheology uye kuchengetwa kwemvura kwepende uye putty kudzivirira kuputika uye kurasikirwa kwehupfu.
mushonga
Mundima yemishonga, HPMC inonyanya kushandiswa semishonga yemishonga, kusanganisira:
Kuputira kwepiritsi: Senge piritsi yekuputira zvinhu, inopa hunyoro-uchapupu, solubilization uye inosimudzira-kuburitsa mabasa ekuvandudza kugadzikana uye kutaridzika kwemushonga.
Gel: inoshandiswa kugadzira mishonga yemishonga, inopa kunamatira kwakanaka uye biocompatibility.
chikafu
HPMC inonyanya kushandiswa se thickener, emulsifier uye stabilizer muindasitiri yechikafu, kusanganisira:
Zvigadzirwa zveNoodle: Wedzera kuoma uye elasticity yehupfu, kunatsiridza kuravira uye magadzirirwo.
Zvigadzirwa zvemukaka: Se emulsifier uye stabilizer, inodzivirira stratification uye kunaya kwezvigadzirwa zvemukaka uye inovandudza kugadzikana kwechigadzirwa.
Makemikari ezuva nezuva
Mumakemikari ezuva nezuva, HPMC inoshandiswa zvakanyanya seyakasimba uye inosimbisa, kusanganisira:
Shampoo uye gel yekugeza: Ipa ine mwero viscosity uye rheology yekuvandudza chigadzirwa chekushandisa ruzivo.
Zvigadzirwa zvekuchengetedza ganda: Seyakakora uye yekunyorovesa, inosimudzira iyo moisturizing mhedzisiro uye ruzivo rwekushandisa kwechigadzirwa.
4. Zvimwe zvinangwa zvakakosha
HPMC inogona zvakare kushandiswa mune mamwe akakosha minda, senge oiri munda migodhi, ceramic indasitiri, indasitiri yemapepa, nezvimwe.
Kugadzirwa kweOilfield: inoshandiswa mukuchera zvinwiwa uye zvinwiwa zvinoputika kuti zvipe yakanakisa kukora uye kurasikirwa kwemvura kudzikisa zvivakwa.
Ceramic industry: inoshandiswa sebhainda uye inomisa mumiriri kuvandudza kugadzikana uye fluidity yeceramic slurry.
Indasitiri yekugadzira mapepa: inoshandiswa kugadzirisa pamusoro pepepa kuwedzera simba rayo uye kudzivirira mvura.
Seyakawanda inoshanda cellulose derivative, HPMC ine yakanakisa yemuviri uye makemikari zvimiro uye yakafara tarisiro yekushandisa. Mhando dzakasiyana dzeHPMC dzine maitiro avo maererano ne viscosity, dhigirii rekutsiva uye kushandiswa. Kusarudza iyo yakakodzera HPMC mhando zvinoenderana nezvinodiwa zvekushandisa kunogona kuvandudza zvakanyanya kuita kwechigadzirwa uye mhando. Nekufambira mberi kwesainzi uye tekinoroji uye nekuwedzera kwenzvimbo dzekushandisa, kushandiswa kweHPMC kuchawedzera uye kwakadzama.
