Hydroxypropyl methylcellulose (HPMC)isiri-ionic, semi-synthetic polymer inoshandiswa zvakanyanya mukuvaka, mushonga, chikafu, zvizorwa uye mamwe maindasitiri minda.
1. Muviri uye makemikari zvinhu
HPMC ipolymer yakagadzirwa kubva kune yakasikwa chirimwa cellulose kuburikidza nekugadzirisa kemikari. Inowanzo chena kana isina-chena poda, isinganakidze, isina kunhuwa uye isina chepfu. Iyo ine yakanaka solubility yemvura uye inogona kunyungudika mumvura inotonhora kana inopisa kuti iite yakajeka kana zvishoma turbid colloidal solution. Hunhu hwayo hwekunyungudika hunokonzerwa nehuwandu hwekutsiviwa, huremu hwemamorekuru uye tembiricha.
2. Kukora
HPMC ine yakanakisa thickening zvivakwa uye inogona zvakanyanya kuwedzera viscosity yemhinduro, ichiita kuti ishandiswe seyakakora mumaindasitiri akadai sezvivakwa, machira, uye mushonga. Semuenzaniso, mudhaka resimende, inogona kuwedzera kushanda kwayo uye kuita kwekuvaka.
3. Kuchengeta mvura
HPMC inogona kunyatso kudzikisa kubuda kwemvura uye kuvandudza simba rekuchengetedza mvura yezvinhu. Ichi chivakwa chinonyanya kukosha muindasitiri yekuvaka. Semuenzaniso, kuwedzera HPMC kune simende dhaka uye gypsum-based zvinhu zvinogona kuwedzera nguva yavo yakavhurika, kunatsiridza kunaka kwekuvaka, uye kuderedza kuputika.
4. Kunamatira
Nekuda kwehunhu hwayo hwakanaka hwekunamatira, HPMC inoshandiswa zvakanyanya mumatairi anonamira, machira, anonamira uye mamwe minda. Mumataira anonamira, anogona kuwedzera simba rekubatanidza uye kuvandudza kureruka kwemabasa ekuvaka.
5. Lubricity
HPMC inoratidzira lubricity yakanaka mune aqueous solution, iyo inoita kuti ive yakanaka lubricant mukugadzirwa kwekuvaka, machira, zvizorwa uye mapiritsi emishonga, kuvandudza kushanda kwechigadzirwa.
6. Chiitiko chepamusoro
Iyo molecular chimiro cheHPMC ine hydrophilic uye hydrophobic mapoka, ayo anoita kuti ive neimwe nzvimbo yebasa uye inogona kuita basa re emulsification, kumiswa, kupararira uye zvichingodaro. Nokudaro, inoshandiswawo mukuputira, emulsion polymerization, detergents uye zvimwe zvigadzirwa.
7. Munyu kuramba uye pH kugadzikana
HPMC is a non-ionic polymer substance, saka haina kugadzikana kune electrolytes uye haisi nyore kudonha neinorganic munyu. Pamusoro pezvo, yakanyatsogadzikana mupH ye3 kusvika 11 uye inokodzera kwakasiyana siyana.
8. Firimu-kugadzira pfuma
HPMC inogona kuumba mafirimu akajeka pamusoro pezvinhu zvakasiyana-siyana zvine simba rakanaka remagetsi uye kushanduka, saka inoshandiswa zvakanyanya mumishonga (tablet coating), chikafu (yekudzivirira firimu), coating (kuumba firimu rubatsiro), nezvimwewo.
9. Kuramba kwekushisa
HPMC ine kugadzikana kwakanaka kwekupisa uye inogona kuramba ichigadzikana kune imwe tembiricha. Ichapinda mukati mekupisa gelation mune aqueous mhinduro pasi pesimba rekushisa, ndiko kuti, ichagadzira gel pane imwe tembiricha uye inonyungudika zvakare mushure mekutonhora. Ichi chivakwa chinoshandiswa zvakanyanya mukuvaka, chikafu uye maindasitiri emishonga.
10. Biocompatibility uye kuchengeteka
HPMC isiri-chepfu, isingashatise polymer zvinhu zvine biocompatibility yakanaka, saka inoshandiswa zvakanyanya mumaindasitiri emishonga uye ezvekudya. Semuyenzaniso, inogona kushandiswa mumishonga inosimudzira-inoburitsa masisitimu, madonhwe emaziso makobvu, uye makobvu echikafu uye emulsifiers.
Nzvimbo dzekushandisa
Nekuda kwehunhu hwayo hwakanaka hwemuviri nemakemikari, HPMC inoshandiswa zvakanyanya mundima dzinotevera:
Indasitiri yekuvaka: inoshandiswa seyakakora uye inochengeta mvura mumiriri wesamende dhaka, mataira anonamira, putty poda, uye zvigadzirwa zvegypsum kuvandudza kuita kwekuvaka uye kunamatira.
Indasitiri yemishonga: inoshandiswa semushonga wemishonga yekunamira piritsi, inosimudzira-inoburitsa zvinhu, emulsifiers uye stabilizers, nezvimwe.
Indasitiri yechikafu: inoshandiswa sechikafu chakakora, emulsifier, uye stabilizer yeaizi cream, muto, sosi uye zvimwe zvigadzirwa.
Indasitiri yezvizoro: inoshandiswa muzvigadzirwa zvekuchengetedza ganda, shampoo, mushonga wemazino, nezvimwewo, kupa kukora, emulsification uye moisturizing mhedzisiro.
Indasitiri yekupfekedza: inoshandiswa seyakakora uye firimu-kuumba rubatsiro rwemvura-based coatings kuti ivandudze kufanana uye kugadzikana kwejasi.
HPMCchinhu chakanakisa chepolymer chine hunhu hwekukora, kuchengetedza mvura, kuumbwa kwemafirimu, mafuta ekuzora, uye kunamatira, uye haina chepfu uye haina kukuvadza, inokodzera maindasitiri mazhinji. Inoshandiswa zvakanyanya mukuvaka, mushonga, chikafu, cosmetics, coatings uye mamwe minda kuvandudza chigadzirwa mhando uye kuita. Mune ramangwana, nekufambira mberi kwetekinoroji uye kukura kwemusika kudiwa, chiyero chekushandisa cheHPMC chinogona kuwedzerwa uye kuita basa rakakosha.
