IHydroxyethyl methyl cellulose
I-Hydroxyethyl methyl cellulose (HEMC) yalungiswa ngokwethula i-ethylene oxide substituent ku-methyl cellulose (MC). Ukubekezelelwa kukasawoti kwakungcono kunokwe-polymer engakhonjwanga, futhi izinga lokushisa le-gel le-methyl hydroxyethyl cellulose laliphezulu kunelithi methyl cellulose.
Ⅰ.Ukusebenza ngokubambisana
1. Ukubukeka: I-White emhlophe noma efanayo emhlophe, awukho umagazini okwenziwa ngomshini, onephunga futhi ongathandeki
2. Ukushisa kwe-Gel (℃): 60-90
3. Okuqukethwe kwamanzi (Wt%): ≤5.0
4. Okuqukethwe kwe-Ash (Wt%): ≤5.0
5.HP: 5.0-8.0
6. Ubuncane: ≥80 Mesh
7. I-Viscosity (mPa.s, isixazululo samanzi esingu-2%, 20 ± 0.2 ℃): 100000-20000
Ain ukusebenza okuyisisekelo kwezobuchwepheshe
1. I-solubility: imodeli H ku-HEMC ingahlakazwa emanzini abandayo nangamanzi ashisayo, kuyilapho imodeli L ingancibilika kuphela emanzini abandayo, kuyilapho i-HEMC inganyibilikiswa lapho kuncibilikiswa izakhi eziningi. I-HEMC ephethwe ebusweni ihlakazeka emanzini abandayo futhi ayihlanganisi. Kodwa-ke, ingaqedwa ngokushesha ngokulungisa inani layo le-pH libe ngu-8-10
2. Ukuzinza kwe-PH: inani le-pH ebangeni lokushintshwa kwe-viscosity engu-2-12 lincane, ngale kwaleli banga le-viscosity liyancipha
3. I-HEMC inezimpawu zokuqina, ukumiswa, ukuhlakazwa, ukunamathela, ukumiswa, ukwenziwa kwefilimu nokugcinwa kwamanzi, namandla ayo okubamba amanzi anamandla kune-methylcellulose. Ukuqina kwe-Viscosity, ukumelana nobala nokusakazeka kungcono kune-hydroxyethyl cellulose
Ⅲ. Ukusetshenziswa nokuqapha
I-HEMC isetshenziswa kakhulu ekugqokeni i-latex esekwe emanzini, izinto zokwakha nezokwakha, uyinki wokuphrinta, ukubhola uwoyela, njll
Ⅳ. Iphakheji nokugcina
1. Lo mkhiqizo unedatha yokuphepha ehambisanayo nedatha yemvume yokuhamba yokuphepha
Lo mkhiqizo ugcwele ngamaphepha angama-25 kg e-kraft kanye nesikhwama sefilimu esilingene
3.Store endaweni eyomile, naka umswakama-proof
