Hydroxypropyl methylcellulose (HPMC) is a semi-synthetic, non-chepfu, multifunctional polymer zvinhu zvinoshandiswa zvakanyanya mumishonga, chikafu, cosmetics uye makemikari indasitiri. Mukugadzira detergent, HPMC yave kuwedzera kwakakosha nekuda kwekukora kwayo, kudzikamisa, kunyorova uye zvimwe zvinhu.
1. Basic maitiro eHPMC
HPMC is a cellulose ether compound, iyo inowanikwa kubva kune yakasikwa cellulose kuburikidza nekugadzirisa kemikari. Zvikuru zvayo zvinosanganisira:
Yakanaka kunyungudika kwemvura: HPMC inogona kukurumidza kunyungudika mumvura inotonhora kuti igadzire yakajeka uye viscous mhinduro.
Kukora mhedzisiro: HPMC ine yakanakisa thickening mhedzisiro, inogona zvakanyanya kuwedzera viscosity yemhinduro pane yakaderera concentrations, uye inokodzera akasiyana emvura magadzirirwo.
Mafirimu-ekugadzira zvimiro: Mushure memvura yanyungudika, HPMC inogona kuumba inochinjika uye yakajeka firimu kuti iwedzere kunamatira kwezvinosuka.
Antioxidation uye kugadzikana kwemakemikari: HPMC ine yakakwira makemikari inertness, inogona kuramba yakagadzikana munzvimbo dzakasiyana siyana dzemakemikari, ine acid uye alkali inodzivirira, uye ine antioxidant.
Moisturizing pfuma: HPMC ine yakanaka yekunyorovesa kugona uye inogona kunonoka kurasikirwa kwemvura, kunyanya muzvigadzirwa zvekuchengetedza ganda.
2. Iyo nzira yekuita kweHPMC mune detergents
Mukugadzira detergent, kunyanya mvura yekuchenesa, kugadzikana ndechimwe chezvinhu zvayo zvinokosha. Detergents inofanirwa kuchengetedza yakagadzikana yemuviri nemakemikari zvivakwa kwenguva yakareba, uye HPMC inoita basa rakakosha mune izvi, kunyanya mune zvinotevera zvinhu:
Dzivirira kupatsanurwa kwechikamu: Mishonga yemvura inowanzove neyakasiyana-siyana senge mvura, surfactants, thickeners, zvinonhuhwirira, nezvimwewo, izvo zvinowanzoita kupatsanurwa kwechikamu panguva yekuchengetedza kwenguva refu. Iko kukora mhedzisiro yeHPMC inogona zvinobudirira kuwedzera viscosity yehurongwa, ichiita kuti chikamu chimwe nechimwe chipararire zvakaenzana uye kudzivirira stratification uye kunaya kwemvura.
Kuvandudza kugadzikana kwefuro: Munguva yekugeza, kugadzikana kwefuro kwakakosha. HPMC inogona kuwedzera viscosity yemvura uye kunonoka kuputika kwefuro, nekudaro ichivandudza kusimba kwefuro. Izvi zvine simba guru pachiitiko chekushandisa detergent, kunyanya kugeza maoko kana kune zvigadzirwa zvine furo rakasimba rekuchenesa.
Enhanced thickening effect: Iko kukobvu mhedzisiro yeHPMC inogona kuita kuti mvura yekugezesa ive nani uye kudzivirira kuti isanyanya kutetepa kana kukora. Mukati mehupamhi pH renji, kukora mhedzisiro yeHPMC haina kugadzikana, uye inonyanya kukodzera kune yakanyanya alkaline detergent maumbirwo, senge madhishi ekuwachisa uye zvinwiwa zvekuchenesa chimbuzi.
Anti-chando uye kunyunguduka kugadzikana: Mamwe madhishi anodonha kana kupenya munzvimbo dzakaderera tembiricha, zvichiita kuti chigadzirwa chirasikirwe nekuyerera kana kugovaniswa zvisina kuenzana. HPMC inogona kuvandudza kutonhora-kunyunguduka kuramba kweformula, kuchengetedza zvimiro zvemuviri zvisina kuchinjika panguva inodzokororwa kutonhora-kunyorova kutenderera, uye kudzivirira kukanganisa kushanda kweiyo detergent.
Dzivirira kunamatira uye sedimentation: Mune detergents ine particulate matter (senge detergent particles kana scrub particles), HPMC inogona kudzivirira zvimedu izvi kuti zvisagadzikane panguva yekuchengetedza, zvichinyatso kuvandudza kugadzikana kwechigadzirwa.
3. Kushandiswa kweHPMC mumhando dzakasiyana dze detergents
(1). Detergent yezvipfeko
HPMC inoshandiswa seyakakora uye inodzikamisa mune zvekusuka mbatya. Basa rayo guru nderokudzivirira stratification ye detergents, kuwedzera kugadzikana kwefuro, uye kuve nechokwadi chekugovera yunifomu yezvigadzirwa zvinoshanda panguva yekugeza. Yayo yakanaka biocompatibility uye isiri-chepfu inovimbisa kuti haizokonzerese kushatirwa kweganda kana uchiwacha mbatya.
(2). Dishwashing liquid
Muzvinwiwa zvekusuka ndiro, HPMC haingobatsiri kuvandudza mvura, asi zvakare inosimudzira kusimba kwefuro uye inosimudzira ruzivo rwemushandisi. Panguva imwecheteyo, inogona kudzivirira kunaya uye kunaya kwevanoshandisa surfactants, kuchengetedza chigadzirwa chakajeka uye chakajeka panguva yekuchengetedza.
(3). Zvigadzirwa zvekuchenesa zvizorwa
HPMC inowanzo shandiswa muzvigadzirwa zvakaita seyekuchenesa kumeso uye yekugezesa gel. Basa rayo guru nderekuvandudza magadzirirwo uye fluidity yechigadzirwa ichipa hunyoro hunoita. Sezvo HPMC pachayo isiri-chepfu uye yakapfava, haizokonzeri kutsamwa kweganda uye yakakodzera kushandiswa mukuchenesa zvigadzirwa zvemhando dzakasiyana dzeganda.
(4). Industrial cleaners
Pakati pezvigadzirwa zvemaindasitiri, kugadzikana uye kukora kweHPMC kunoita kuti ive yakanyatsokodzera nzvimbo dzakaomarara dzemaindasitiri. Semuenzaniso, mune zvekuchenesa simbi, inochengetedza kugovaniswa kwezvinhu zvinoshanda uye inodzivirira stratification panguva yekuchengetedza.
4. Zvinhu zvinokanganisa kugadzikana kwe detergents inovandudzwa neHPMC
Kunyangwe HPMC ichiratidza kugadzikana kwakanakisa mukugadzirwa kwe detergent, mhedzisiro yayo ichakanganiswa nezvimwe zvinhu:
Concentration: Huwandu hweHPMC hunokanganisa zvakananga kugadzikana uye fluidity ye detergent. Kuisa pfungwa kwakanyanyisa kungaita kuti detergent ive yakanyanya viscous, inokanganisa ruzivo rwemushandisi; nepo fungidziro yakaderera zvikuru inogona kusashandisa zvizere maitiro ayo ekudzikamisa.
Tembiricha: Iko kukora mhedzisiro yeHPMC inokanganisa tembiricha, uye viscosity yayo inogona kuderera pakupisa kwepamusoro. Naizvozvo, kana ichishandiswa munzvimbo dzekushisa kwepamusoro, fomula inoda kugadziridzwa kuchengetedza viscosity yakakodzera.
pH kukosha: Kunyange zvazvo HPMC iine kugadzikana kwakanaka muhupamhi hwepH, yakanyanyisa asidhi uye alkali nharaunda inogona kuramba ichikanganisa kushanda kwayo, kunyanya mune yakanyanya alkaline formula, nekugadzirisa chikamu kana kuwedzera zvimwe zvinowedzera kusimba.
Kugarisana nezvimwe zvikamu: HPMC inofanirwa kuve nekuenderana kwakanaka nezvimwe zvikamu mu detergents, senge ma surfactants, zvinonhuhwirira, nezvimwewo, kudzivirira kuita kwakashata kana kunaya kwemvura. Kazhinji kana uchigadzira resipi, kuyedza kwakadzama kunodiwa kuti uve nechokwadi chekubatana kwezvese zvinongedzo.
Kushandiswa kweHPMC mune zvekugezesa kune zvakakosha pakuvandudza kugadzikana kwechigadzirwa. Iyo haingodzivisi kupatsanurwa kwechikamu che detergents uye inovandudza furo kugadzikana, asi zvakare inosimudzira kutonhora-kunyungudika kuramba uye inovandudza fluidity. Panguva imwecheteyo, kugadzikana kwemakemikari eHPMC, kupfava uye kusiri muchetura kunoita kuti ive yakakodzera kune dzakasiyana siyana dzekugadzira detergent, kusanganisira zvemumba, zveindasitiri uye zvemunhu zvekuchengeta. Nekudaro, mashandisiro ekushandisa kweHPMC achiri kuda kugadziridzwa zvinoenderana nemafomula chaiwo kuti ive nechokwadi chekuita kwakanyanya munzvimbo dzakasiyana.
