HPMC inogona kunyungudutswa musolvent yakasanganiswa nemvura inotonhora uye organic matter kuti igadzire inoonekera viscous mhinduro. Mushonga wemvura une basa repamusoro, kujeka kwepamusoro uye kugadzikana kwakasimba. Kuparara kwayo mumvura hakukanganiswi nepH. Iine kukora uye anti kutonhora mhedzisiro mu shampoo uye gel yekugeza, uye ine kuchengetedza mvura uye yakanaka yekugadzira firimu zvimiro zvebvudzi neganda. Nekuwedzera kwakanyanya kwezvinhu zvekutanga, cellulose (antifreeze thickener) inogona kuderedza zvakanyanya mutengo uye kuwana mhedzisiro yakanaka kana ichishandiswa mu shampoo uye gel yekugeza.
Iyo yemazuva ese kemikari giredhi yemvura inotonhorera instant hydroxypropyl methyl cellulose ine inotevera chigadzirwa maitiro:
1. Yakanakisa kuchengetedza mvura kuita. HPMC ine hydrophilic maitiro. Inogona kuchengetedza yakakwira kuchengetwa kwemvura mune paste, paste uye kunamira zvigadzirwa.
2. Mvura inotonhora instant hydroxypropyl methylcellulose HPMC inoshandisa zvinhu zvakasvibirira zvechisikigo, izvo zvine hunyoro hunoita, kushatirwa kwakaderera, kuchengetedza kwezvakatipoteredza uye kuchengeteka.
3. PH inenge yakagadzikana, uye viscosity yeaqueous solution inowanzogadzikana muhuwandu hwepH3.0 kusvika 11.0.
4. Mushonga wemvura wechigadzirwa une basa repamusoro, emulsification, colloid kudzivirira uye kugadzikana kwehukama. Kudzvinyirirwa kwayo kwepamusoro kunenge 2% uye mhinduro ine mvura ndeye 42-56dyn/cm.
5. Kukora uye kunyungudika kwemvura, inogona kukurumidza kunyungudutswa mumvura inotonhora, mamwe organic solvents uye masanganiswa ane organic solvents.
6. Kuwedzera viscosity: kana chidimbu chiduku chekuparara chichiwedzerwa, sarudzo yakajeka ye viscous ichaumbwa, iyo ine maitiro ekushanda kwakagadzikana uye kujekesa kwepamusoro. Iyo solubility ichachinja ne viscosity. Iyo yakaderera iyo viscosity, iyo yakakura dhigirii yekuparara, iyo inogona zvinobudirira kuvandudza kuyerera kugadzikana kwehurongwa.
7. Yakanakisa munyu kuramba. HPMC isiri-ionic polima, iyo yakagadzikana muorganic electrolyte aqueous solution kana organic electrolyte.
8. Thermal gelation: kana mhinduro yemvura inopisa kune imwe tembiricha, ichava opaque kusvikira flocculation state yagadzirwa, iyo ichaita zvachose kuti mhinduro irasikirwe neviscosity yayo. Nekudaro, ichachinja kune yekutanga mhinduro mamiriro mushure mekutonhora. Kune dambudziko remafuta gel, tembiricha inonyanya kuenderana nerudzi rwechigadzirwa, kugadziriswa kwemhinduro uye chiyero chekupisa.
9. HPMC ine zvimwe zvinhu mumunda wekushandiswa kwemakemikari ezuva nezuva, zvakadai seyakanakisa firimu-kugadzira zvinhu, yakakura enzyme kuramba, kupararira uye bonding properties.
