Detergent Thickener Hydroxypropyl Methyl Cellulose Eteri HPMC
High ViscosityHPMChydroxypropyl methyl celluloseThickenerNokuda kweputty powder:
1) Chitarisiko:HPMCis nonionic cellulose ether, chena greyish-white powder kana granule, isinganhuhwi uye haina kunaka, inonyungudika mumvura inotonhora, glacial acetic acid, ethanol, methanol uye propylene glycol, inonyungudika zvishoma muacetone zvichienderana nehuwandu hwekutsiva, isinganyungudika mumvura inopisa. , ethylene glycol uye toluene.HPMC inonyungudika mumusanganiswa we10% methanol uye 90% methylene chloride kuita colloidal mhinduro.
2) Mhinduro yeHPMC ine chiitiko chepamusoro, kujeka kwepamusoro, uye kuita kwakagadzikana.Kana ichipisa pane imwe tembiricha, mhinduro inova nemakore kana kuumba flocculent gel.Zvisinei, mhinduro inova yakajeka zvakare mushure mekutonhora.Mhando dzakasiyana dzeHPMC dzine tembiricha dzakasiyana dzegelation.Solubility inosiyana zvichienderana ne viscosity.Iyo yakaderera iyo viscosity, iyo yakanyanya solubility ine.Mhando dzakasiyana dzeHPMC dzakasiyana mune zvimwe zvivakwa uye kunyungudika kwavo mumvura hakukanganiswe nepH.
3) Particle saizi: 100% kupasa mwero mu80 mesh.
4) Density inooneka: 0.25-0.70 g/mL (kazhinji inenge 0.5 g/mL), density chaiyo 1.26-1.31mL.
5) Kupisa kwemavara: 190-200 ° C;Carbonization tembiricha: 280-300°C.
6) Kushungurudzika kwepamusoro: 42-56 dyn / cm (2% aqueous solution).
7) Iyo yepamusoro methoxy yemukati muHPMC, yakadzika gelation tembiricha, uye yakanyanya solubility mumvura uye pamusoro pekuita.
8) HPMC ine humwe humwe hunhu, semuenzaniso, kukora pfuma, pH kugadzikana, kuchengetwa kwemvura, yakanakisa firimu-yekugadzira pfuma, yakanaka kuparadzira uye kugona kunamatira.

Zvigadzirwa zveYoungcel zvinosanganisira marudzi ese ezvigadzirwa zvemvura zvakaita sezvicheneso zvepasi, zvekugezesa uye zvigadzirwa zvekusuka ndiro zvine pH pakati.6- 8
Youngcelinogona kushandiswa seyakakora kugadzirisa iyo rheology yemvura yekugezesa, kugadzirisa kune inodiwa chitarisiko uye kwakaringana kuenderana.
Youngcel inoita kuti viscous mafomula uye gel yekuchenesa ive yakawedzera kubatsira uye zvakanyanya kunaka, nekutiYoungcelinoregedza makuchenesa gel asara pamusoro uye ashande kwenguva yakareba, saka zvirinani kuchenesa mhedzisiro.
- Kukora mhedzisiro
- Kugadziriswa kwekuenderana
- Kuenderana neiyo ionic surfactants
- Mhinduro dzekujeka kwepamusoro
