Isihluzi seThickener Hydroxypropyl Methyl Cellulose Etere HPMC
Viscosity ephezuluHPMCi-hydroxypropyl methyl celluloseThickenerNgomgubo weputty:
1) Imbonakalo:HPMCyi-nonionic cellulose ether, emhlophe greyish-white powder okanye granule, ayinavumba kwaye ayinancasa, inyibilika emanzini abandayo, iglacial acetic acid, i-ethanol, i-methanol kunye nepropylene glycol, inyibilika kancinane kwi-acetone ngokuxhomekeke kwiqondo lokufakela endaweni, ayinyibiliki ngokuthe ngqo emanzini ashushu. , i-ethylene glycol kunye ne-toluene.I-HPMC inyibilika kumxube we-10% ye-methanol kunye ne-90% ye-methylene chloride ukwenza izisombululo ze-colloidal.
2) Isisombululo se-HPMC sinomsebenzi ongaphezulu, ukukhanya okuphezulu, kunye nokusebenza okuzinzileyo.Xa kushushu kwiqondo elithile lobushushu, isisombululo siba ngamafu okanye senze ijeli ehlumayo.Nangona kunjalo, isisombululo siyacaca kwakhona emva kokupholisa.Iindidi ezahlukeneyo ze-HPMC zinobushushu obuhlukeneyo be-gelation.I-solubility iyahluka kunye ne-viscosity.I-viscosity ephantsi, i-solubility ephezulu inayo.Iindidi ezahlukeneyo ze-HPMC zahlukile kwezinye iipropati kwaye ukunyibilika kwazo emanzini akuchatshazelwa yi-pH.
3) Ubungakanani be-particle: 100% izinga lokupasa kwi-80 mesh.
4) Ubuninzi obubonakalayo: 0.25-0.70 g / mL (ngokuqhelekileyo malunga ne-0.5 g / mL), ubuninzi obuthile 1.26-1.31mL.
5) Ubushushu bokutshintsha umbala: 190-200 ° C;Ubushushu beCarbonization: 280-300°C.
6) Uxinzelelo lomphezulu: 42-56 dyn / cm (2% isisombululo samanzi).
7) Umxholo ophezulu we-methoxy kwi-HPMC, ubushushu obuphantsi be-gelation, kunye nokunyibilika okuphezulu kwamanzi kunye nomsebenzi womphezulu.
8) I-HPMC inezinye iimpawu, umzekelo, ukuqina kwepropati, ukuzinza kwe-pH, ukugcinwa kwamanzi, ipropati ebalaseleyo yokwenza ifilimu, ukusabalalisa okulungileyo kunye nokukwazi ukunamathela.

8) I-HPMC inezinye iimpawu, umzekelo, ukuqina kwepropati, ukuzinza kwe-pH, ukugcinwa kwamanzi, ipropati ebalaseleyo yokwenza ifilimu, ukusabalalisa okulungileyo kunye nokukwazi ukunamathela.
Iimveliso zeYoungcel zibandakanya zonke iintlobo zeemveliso ezingamanzi ezifana nezicoci zomgangatho, izicoci kunye neemveliso zokuvasa izitya ezine pH phakathi.6- 8
Abaselulacelingasetyenziswa njenge-thickener yokulungelelanisa i-rheology ye-detergents yolwelo, ukulungelelanisa imbonakalo efunekayo kunye nokuhambelana okufanelekileyo.
Abaselulacel yenza ukuba iifomyula ze-viscous kunye nezicoci zejeli zibe luncedo ngakumbi kwaye zithandeke ngakumbi, kubaAbaselulaceliya kuvumela abacoci bejeli bashiye umphezulu kwaye basebenze ixesha elide, ngoko ke iziphumo ezingcono zokucoca.
- Iziphumo ezityebileyo
- Ukulungelelaniswa kokuhambelana
- Ukuhambelana ne-ionic surfactants
- Izisombululo zokucaca okuphezulu
