Mukugadzirwa kwesipo yemvura,hydroxypropyl methylcellulose (HPMC)chinhu chinowanzo shandiswa chinosimbisa, chinosimbisa, uye chinogadzira firimu. Hachingogadziri chitarisiko chechigadzirwa uye hunhu hwerheological chete, asiwo chinowedzera ruzivo rwemushandisi. Tsananguro yakadzama inotevera yekuti HPMC inoshandiswa sei mu sipo yemvura ichafukidza misimboti yayo, mhedzisiro, mashandisirwo, matanho ekudzivirira, uye zvakanakira mashandisirwo ayo.
1. Mashandiro anoita HPMC muSipo yemvura
HPMC imhando ye nonionic cellulose ether inobva mu cellulose yechisikigo uye inogadziriswa kuburikidza ne methylation ne hydroxypropylation. Ine hunhu hwakanaka hwekunyunguduka, emulsification, uye kukora. Nzira huru dzekushanda kweHPMC mu sipo yemvura dzinosanganisira:
Kukora: HPMC inokura mumvura kuti igadzire mushonga wakakora, zvichiita kuti sipo iwedzere kukora, zvichiita kuti mvura ifambe zvakanaka, uye zvinodzivirira kuti chigadzirwa chisanyanya kunyorova.
Kudzikamisa: Mumasystem ane ma surfactants, HPMC inogadzira colloid inodzivirira, ichidzivirira kupatsanurwa kwemafuta nemvura, nokudaro ichivandudza kugadzikana kwemushonga. Kugadzira firimu uye Kunyorovesa: HPMC inogadzira firimu rakapfava pamusoro peganda, ichideredza kurasikirwa nemvura uye ichipa hunyorovesa.
Kuvandudza Chitarisiko uye Mashandisirwo: Inoita kuti sipo ive mvura yakajeka uye yakafanana, ichivandudza magadzirirwo ayo uku ichigadzira furo rakatsetseka uye rakapfava.
2. Maitiro Ekuwedzera HPMC muSipo Yemvura
Mukugadzirwa chaiko, kushandiswa kweHPMC kunoda kunyatsotarisa nzira yekunyungudutsa uye kurongeka kwekuwedzera zvinhu. Zvikasadaro, zvinogona kukonzera kuungana kana kupera zvachose. Matanho akajairika ekushandisa ndeaya anotevera:
2.1. HPMC isati yapararira
Sanganisai upfu hweHPMC nehuwandu hwakakodzera hweglycerin, propylene glycol, kana huwandu hushoma hwesurfactant kudzivirira kuungana kana yaiswa mumvura.
2.2. Nzira yekuparadzira mvura inotonhora
Isa zvishoma nezvishoma HPMC yakapararira mumvura inotonhora (tembiricha yemukamuri), uchikurunga uku uchiwedzera zvinhu kuti zvive nechokwadi chekuti zvinopararira zvakaenzana.
Pakutanga, HPMC inenge yave muchimiro cheupfu uye zvishoma nezvishoma inozvimba painonwisa mvura.
2.3. Nzira yekudziyisa
Pisai zvishoma nezvishoma musanganiswa une HPMC kusvika pa60°C kuti munyatsozvimba cheni dze cellulose mogadzira mhinduro yakafanana, inoonekera.
Mushure mekunyungudika, tonhodza kusvika patembiricha yemukamuri kuti uwane mhinduro yakasimba yemuto.
2.4. Kuwedzera Sipo Yepasi
Wedzera mushonga weHPMC wakanyungudutswa mufomura huru yesipo yemvura zvichienderana nehuwandu hwakakodzera wobva wasanganisa zvakanaka.
Chiyero chinowanzova pakati pe0.3% ne1.0%, zvichigadziriswa zvichienderana nekunaka uye kujeka kwesisipo.
3. Chipimo uye Kudzora kweHPMC
Kuwanda kwakaderera (0.1% kusvika 0.3%): Kunovandudza kuyerera kwemushonga wesipo, zvichiita kuti usanyanya kunyorova.
Kuwanda kwemvura kuri pakati nepakati (0.3% kusvika 0.6%): Inowanzoshandiswa mu sipo dzinoonekera kana dzinopenya, inosimbisa mashandiro emuviri pasina kusviba zvakanyanya.
Kuwanda kwakanyanya (0.6% kusvika 1.0%): Kunoshandiswa muzvigadzirwa zvinoda kusimba kwakanyanya, zvakaita sekugeza muviri, sipo dzemaoko, kana sipo dzemhando yepamusoro dzekuchengetedza ganda. Zvakakosha kuziva kuti kuwanda kwakanyanya kunogona kukonzera kudzikira kwefuro kana kuomarara panguva yekuisa, saka sarudzo yakakodzera inofanira kuitwa zvichienderana nenzvimbo yechigadzirwa.
4. Nzira dzekudzivirira pakushandisa HPMC
Kudzivirira Kuungana: HPMC inogadzira firimu rekunze nyore nyore kana yabata mvura, ichifukidza upfu husina kunyunguduka, zvichikonzera mapundu e "fish-eye". Saka, kuaparadzira kana kuchenesa nemvura inotonhora kunokosha.
Kudzora Tembiricha: Usashandise mvura inopisa zvakananga panguva yekunyungudika, sezvo izvi zvichizoguma nekunyungudika kusina kuenzana. Paradzira nemvura inotonhora kutanga, wozopisa kuti inyungudike.
Nhamba ye pH: HPMC yakagadzikana mukati mehuwandu hwe pH hwe 3-11 uye yakakodzera masisitimu mazhinji esipo yemvura. Kuwanda kwe acidic kana alkaline kunogona kukanganisa kunyungudika uye kusimba.
Kuenderana neSurfactants: HPMC inoenderana neanionic, nonionic, uye amphoteric surfactants, asi inofanira kudzivirirwa ne cationic polymers dzakasimba kudzivirira kunaya kwemvura.
Kudzivirira Kusvibiswa neMabhakitiriya: HPMC ipolymer yeorganic inoparadzwa nyore nyore nehutachiona, saka sipo dzemvura dzinoda mushonga unochengetedza wakakodzera.
5. Mabhenefiti eHPMC muSipo dzeLiquid
Kuchengetedzeka uye Kudzivirirwa Kwezvakatipoteredza: Yakabva mu cellulose yechisikigo, haina chepfu uye haitsamwisi, zvichienderana nepfungwa yezvizoro zvegirini.
Kunzwa Kweganda Kusina Kusimba: Inoita firimu rekudzivirira pamusoro peganda, zvichideredza kushatirwa kwesipo.
Mutengo Unodhura: Kana tichienzanisa nemapolymer ekugadzira akadai secarbomer, HPMC inodhura zvishoma uye inopa mhedzisiro yakafanana.
Kuchinjika Kwazvo Kwekugadzira: Inoshanda nemasurfactants akajairika, munyu, uye zvinonhuhwirira, zvichiita kuti kugadzirwa kwemhando dzakasiyana dzesipo yemvura kuve nyore.
Kuchinja-chinja: Hazvingoiti kuti iite gobvu chete, asiwo zvinonyorovesa, zvinovandudza furo, uye zvinodzikamisa sisitimu, zvichipa mabhenefiti akawanda.
6. Maitiro Akajairika
Sipo Yemaoko: HPMC inobvumira sipo dzemaoko kuchengetedza viscosity iri pakati nepakati kunyangwe kana paine huwandu hwakaderera hwesurfactant, zvichiwedzera kunzwa.
Kugeza Muviri: HPMC inoita kuti ganda rive rakapfava uye inowedzera mafuta eganda.
Zvigadzirwa Zvekuchengetedza Vana: Kusatsamwa kwakanyanya uye kunyorova kweHPMC zvinonyanya kukodzera mafomura evana.
Sipo yemvura inopenya zvikuru: Kujeka kwemhinduro dzeHPMC kunogona kushandiswa kugadzira sipo dzemvura dzinopenya dzine mifanidzo inoyevedza.
Chinhu chikuru chekushandisaHPMCMusipo yemvura mune kunyungudika kwakakodzera, kuyera kwakakodzera, uye chiyero chakakodzera. Haingogadzirisi chete kugadzikana uye kugara zvakanaka kwesipo asiwo inovandudza kunzwa kweganda uye chitarisiko. Sechinowedzerwa mukugadzira chinosanganisa kuchengetedzeka, kushanda, uye mutengo wakaderera, HPMC yave chinhu chakakosha musipo yemvura nezvimwe zvigadzirwa zvemakemikari zvezuva nezuva.
