Iyini i-Cellulose Thickener?

by admin on 23-01-11

I-Thickener, eyaziwa nangokuthi i-ejenti ye-gelling, ibizwa nangokuthi i-paste noma iglue yokudla uma isetshenziswa ekudleni. Umsebenzi wawo oyinhloko ukukhulisa i-viscosity yesistimu yezinto ezibonakalayo, ukugcina isistimu yezinto ezibonakalayo esimweni sokumiswa esilinganayo futhi esizinzile noma isimo se-emulsified, noma ukwakha ijeli. Ama-thickeners angakhula ngokushesha...

Ziyini Izici ze-HPMC odakeni oluxutshwe okomile

by admin on 23-01-10

1. Izici ze-HPMC kudaka olujwayelekile lwe-HPMC isetshenziswa kakhulu njenge-retarder kanye ne-ejenti yokugcinwa kwamanzi ekulinganiseni kukasimende. Ezingxenyeni zikakhonkolo nodaka, kungathuthukisa i-viscosity kanye nezinga lokuncipha, kuqinise amandla ahlangene, kulawule isikhathi sokumisa usimende, futhi kuthuthukise amandla okuqala...

Ukusetshenziswa kwe-HPMC embonini yezokwakha

by admin on 23-01-10

I-Hydroxypropyl methyl cellulose, ebizwa ngokuthi i-cellulose (HPMC), yenziwe nge-cotton cellulose emsulwa kakhulu njengento eluhlaza futhi ifakwa etherified ngokukhethekile ngaphansi kwezimo ze-alkali. Yonke le nqubo iqedwa ngaphansi kokuqapha okuzenzakalelayo futhi ayiqukethe izithako ezisebenzayo njengesilwane noma...

Uyenza kanjani i-methylcellulose?

by admin on 23-01-09

Okokuqala, i-cellulose eluhlaza okotini wokhuni/ukotini ocolisisiwe uyachotshozwa, bese u-alkali futhi ugoqe ngaphansi kwesenzo se-caustic soda. Engeza i-olefin oxide (efana ne-ethylene oxide noma i-propylene oxide) ne-methyl chloride ukuze uthole i-etherification. Ekugcineni, ukuwashwa nokuhlanzwa kwamanzi kuyenziwa ukuze kufinyelelwe...
