HydroxyPropyl methylcellose (HPMC) inzira yemashandisirwo ezvekushandisa mune dzakasiyana-siyana maindasitiri, kusanganisira mishonga yemishonga, kuvaka, chikafu uye cosmetics. Izvo Zvishandiso zvinoshandiswa muHPMC Synthesis zvinobva kune zvakasikwa zvinyorwa uye zvidzitiro zvemakemikari zvekugadziridzwa kuti uwane zvivakwa zvaunoda.
Cellulose: izvo zvekutanga
Iyo mainini mainini yeHPMC is cellulose, yakaomarara carbohydrate inowanikwa mune zvinodyara madziro emadziro. Machira uye huni dzemapururu ivhu redzimhosva em cellulose. Cellulose mafaira anotanga kurapwa kuti abvise kusvibiswa uyezve hydrolyzed kuputsa mapopuni madiki madiki polysaccharides. Maitiro acho anosanganisira kushandisa Acids kana enzymes kuti anyaradze zvisungo zveGlycsic aripo muCellulose, zvichikonzera kuchena kakawanda cellulose cellumlose anonzi cellulose.
Propyonexe Oxide: Nhanganyaya yeHydroxyPropyl Group
Mushure mekuwana iyo cellulose ether, iyo inotevera nhanho inosanganisira kuunza hydroxpressl mapoka muCellulose Backbone. Propyonexo oxide is kiyi yehuswa rakabiwa rinoshandiswa nechinangwa ichi. Mukuvapo kweAlkaline Catalyst, profylexie oxide inoreva neiyo hydroxyl mapoka paCellulose Chain, inokonzerwa nekubatanidzwa kweiyo hydroxyprorpropropropropropropropropropropropropropropropropropropropropropropropropropropropyl mapoka eHydroxpropropyl. Kuita uku, kunonzi eritation, kunoita basa rakakosha mukuchinja zvinhu zvemuviri uye zvemakemikari zvemasero, kugadzira hydroxypruppropyl cellulose.
Methyl chloride: Wedzera methyl boka
Muchikamu chinotevera chekuchinja, methyl chloride chinoshandiswa kusuma methyl mapoka pane iyo cellulose backbone. Kuita uku, kunonzi methylation, kunosanganisira kuita metherulose ne methyl chloride pamberi pechikamu. Methyl mapoka anowedzerwa kuHydroxypressleselcellose kuumba hydroxypronylethelose (HPMC). Dhigirii rekutsiva
Alkali: Neutralies uye kudzora viscosity
Mushure mekutsvagira uye methylation matanho, iyo HPMC inokonzeresa inowanzoitika alkaline. Chikamu chakadai sodium hydroxide chinoshandiswa kusarerekera chigadzirwa. Iyi nhanho yakakosha kuzadzisa iyo yaunoda pH level uye kusimudzira kugadzikana kweHPMC. Kuwedzera chigadziko zvakare kunobatsira kudzora zvisizvo zveHPMC mhinduro dzeHPMC, zvichiita kuti vakwanise kuita zvakasiyana-siyana zvekushandisa uko viscosity inoitira basa rakakosha, senge mishonga yemishonga uye zvigadzirwa zvekuvaka.
Kucheneswa uye filtration: kuona kunaka kwemhando
Mushure mekugadziriswa kwemakemikari, zvigadzirwa zveHPMC zvinonatswa kubvisa chero zvigadzirwa zvisina kugadzirwa zvisingaiti, ne-zvigadzirwa, kana kusvibiswa. Kucheneswa uku kunowanikwa uchishandisa maitiro efaira, kuve nechokwadi chekuti iyo yekupedzisira HPMC chigadzirwa inosangana nemhando dzinodiwa mhando. Kucheneswa inhanho yakaoma yekubvisa zvinhu zvisingadiwe izvo zvinogona kukanganisa maitiro uye kuchengetedzwa kweHPMC mune kwayo chinangwa.
Zvikumbiro zve hydroxyprupyl methylcellose
Pharmaceutical: HPMC inoshandiswa zvakanyanya muindasitiri yemishonga seyakagadzirwa, yefirimu yaimbova uye yakadzorwa kuburitswa mumiririri mukugadzira piritsi. Kugona kwayo kuumba mafirimu akajeka kunoita kuti zviite kuti zviite kuti zviite piritsi yekuvhara, kupa dura rekudzivirira uye kusunungurwa kwezvinodhaka.
Kuvaka: Muindasitiri yekuvaka, HPMC inoshandiswa mune yemasimendi-yakavakirwa zvinhu senge moter, stucco, uye madhimoni. Inoita sedhizimusi, mvura inochengetedza mumiriri, uye inovandudza kushanda uye kushamisika.
Indasitiri yechikafu: HPMC inoshandiswa mune indasitiri yechikafu sedhimoni, stabilizer uye emulsifier. Iyo inoshandiswa mune dzakasiyana siyana zvekudya zvekudya, kusanganisira sosi, zvipfeko uye zveshuwa.
Cosmetics: Mune cosmetics, HPMC inoshandiswa muFormas yakadai sekiriniki, marara, uye shampoos kupa chimiro, nekuvandudza kugadzikana, uye kusimudzira kuita kwakazara kwechigadzirwa.
Pendi uye majasi: HPMC inoshandiswa seanoshandiswa sedhizaini uye stabilizer mumvura-yakavakirwa pendi uye zvipfuyo kubatsira kuvandudza rateology yeiyo rateology yechifananidzo.
Zvigadzirwa zvega zvega: HPMC inowanikwa mune dzakasiyana siyana dzekuchengeta zvigadzirwa, kusanganisira mazino ezvigadzirwa uye zvigadzirwa zvezvikwereti, kwauchiita seBinder uye viscossity modifier.
HydroxyprondPropyl methylcellose inzvimbo yakakosha polymer ine huwandu hwakawanda hwekushandisa mune dzakasiyana maindasitiri. Iyo Synthesis yeHPMC inosanganisira kushandiswa kweCellulose, profylone oxide, methyl chloride, alkali uye yekuchenesa matanho ekuvezwa kuti ive yakakwirira mhando chigadzirwa. Iko kuwanda kweHPMC kunobva mukugona kwayo kugadzirisa zvemuviri uye zvemakemikari zvimiro zveCellerulose muCellemical mumishonga, zvekuvakisa, chikafu, chigadzirwa, pendi uye zvigadzirwa zvekutarisira. Kunzwisisa zvigadzirwa zvevhu uye synthesis process inokosheswa kugadzirira HPMC kune chaiyo yekushandisa uye inogadzirisa mashandiro aro mune dzakasiyana siyana mafambiro.
