Hydroxypropylmethylcylosellose (HPMC) uye hydroxyTHELELcellose (HEC) marudzi maviri akajairika eCellulose Derivatives anoshandiswa mumaindasitiri akawanda. Kunyangwe vachigoverana zvakafanana, kune zvakare misiyano yakawanda, kusanganisira makemikari chimiro, zvivakwa zvemuviri, uye zvinoshandiswa.
Chemical chimiro
Musiyano mukuru pakati peHPMC uye Hec ndiyo yavo yemakemikari chimiro. HPMC ndeye synthetic polymer yakagadzirwa nekuita cellulose ine procleene oxide uye methyl chloride. Maitiro acho anogadzira polysers avo vese hydrophilic uye lipeilic, vachiita kuti vawedzere zvinoshandiswa muzvakawanda zvigadzirwa zveindasitiri, kusanganisira chengetedzo yemunhu uye mishonga.
Hec, kune rumwe rutivi, iri biopolymer yakawanikwa kubva ku cellulose. Iyo inogadzirwa nekuita kwemheremellose neErthylene oxide, iyo inogadzira hydroxythersl mapoka pane iyo cellulose mamorekuru. Izvi zvinoumba poldu-soluble polymer ine zvakanakisa uye rateological zvivakwa uye zvikaita kuti zviite zvakakodzera kuti zviwedzere huwandu hwekushandisa.
Zvivakwa zvemuviri
HPMC uye Hec ine zvakasiyana zvivakwa zvemuviri nekuda kwezvivakwa zvavo zvakasiyana zvemakemikari. Semuenzaniso, HPMC iri kuwedzera hydrophobic kupfuura yehec, zvinoreva kuti haina kunyanyoka mumvura. Naizvozvo, HPMC inowanzoshandiswa sechiStabilizer uye emulsifier mune zvigadzirwa-zvakavakirwa zvigadzirwa zvakadai nemazvo uye zvinogara. HEC, kune rumwe rutivi, inonyatso kuvezwa mumvura uye inowanzoshandiswa seyakakwenenzverwa uye nemumiririri wemukati mumvura mhinduro.
Imwe nzvimbo yemuviri yeHPMC uye Hec ndeyevisipa yavo. Hec ine yepamusoro viscosity kupfuura HPMC, zvinoreva kuti inonyanya kushanda pamhinduro dzakakora uye kugadzira gerles. Ichi chivakwa chinoita kuti Hec yakanakira kushandiswa mumatanda uye hukuru, zvinoshambidza, uye zvimwe zvigadzirwa zvinoda huwandu hwekubatanidza.
Nzvimbo dzekushandisa
HPMC uye HPMC inoratidzika zvakanyanya muindasitiri akasiyana siyana. HPMC inowanzo shandiswa muindasitiri yemishonga sekumaodzanyemba, kuungana, uye masisitimu anodhaka. Izvo zvinoshandiswawo seanotenda uye emulsifier mune zvigadzirwa zvega zvega senge shampoos, soaps uye cosmetics. HPMC inoshandiswawo seinowedzera chikafu uye mugadzirwa yepepa zvigadzirwa.
Hec, kune rumwe rutivi, inowanzoshandiswa seyakakwenenzverwa uye gomba mumiririri mune akasiyana maindasitiri. MuPendi uye Coatings Indasitiri, Hec inoshandiswa seanoti, rheology modifier uye kumiswa rubatsiro. Iyo inoshandiswawo seyemvura-yekuchengetedza mvura mune yekuvaka indasitiri uye mukugadzira madekisheni, machira uye ceramics.
HPMC uye HPM CLE maviri Cellulose DEVILATIVES NEZVINHU ZVAKAITWA ZVAKAITWA, ZVINHU ZVINOGONESA UYE ZVINHU ZVINOGONESA. HPMC iri kuwanda hydrophobic uye inoshandiswa mune dzakasiyana-siyana maindasitiri, nepo hec iri manyorerwo-svutugadzike uye yakanakira kumhinduro dzemvura uye kugadzira magedhi. Izvo zvakakosha kuti unzwisise mutsauko uripo pakati peiyi miviri yemaseru-cellulose Decivatives kana uchisarudza iyo yakakodzera chinongedzo chekushandisa chairo.
