Katundu ndi kusamala kwa hydroxyethyl cellulose

Hydroxyethyl cellulose (hec) ndi chikasu choyera kapena chowoneka bwino, chosawoneka bwino, chomwe chimakonzedwa ndi makonda a alkalinine celluuse (kapena chlleohydrin). Cellowec cellulose yopanda. Kuphatikiza pa kukula, kuyimitsa, kumangiriza, kuyandama, mawonekedwe a filimu, obalalitsa, osunga madzi ndikuteteza Colloid, ali ndi zinthu zotsatirazi:

1. Hec amasungunuka m'madzi otentha kapena madzi ozizira, kutentha kwambiri kapena kuwira popanda mpweya, kotero kuti ili ndi mawonekedwe osiyanasiyana komanso osakhala otenthetsera;

2. Sikuti ndi ionic ndipo imatha kukhala yolumikizana ndi ma pointer ena osungunuka madzi, okonda, komanso mchere. Ndibwino kwambiri colloidal yothetsera mavuto ambiri a electrolyte;

3. Kuchuluka kwa madzi ndikokwera kwambiri ngati kwa methyl cellulose, ndipo ili ndi njira yabwino kwambiri.

4. Poyerekeza ndi methyl cellose ndi hydroxypropyl methy cellose, kuthekera kwa hec ndiye choyipa kwambiri, koma kuthekera kwa coloid ndikolimba. Chifukwa cha zabwino zake, kuyimitsa, kubalalitsa, kuponderezedwa, kupanga mafilimu, kuteteza, chakudya, pepala ndi polymerization.

Kusamalitsa:

Popeza ma sydroxyethyl opaleshoni ali ndi ufa kapena cellulose yolimba, ndizosavuta kusamalira m'madzi malinga ngati zinthu zotsatirazi zimakhudzidwa. a

1. Asanayambe ndi mutawonjezera hydroththyl cellulose, ziyenera kulimbikitsidwa mosalekeza mpaka yankho likaonekeratu. a

2. Iyenera kukhala yosemphana pang'ono mu thanki yosakanikirana, musawonjezere mwachindunji za hydroxethyl cellulose kapena hydroxethyl cellulose yomwe yapanga zotupa ndi mipira mu thanki yosakanikirana. a

3. Kutentha kwa madzi ndi mtengo wa PH m'madzi kumakhala chibwenzi chodziwikiratu ndi kusungunuka kwa hydroxethyl cellulose, chidwi chachikulu chimayenera kulipidwa. a

4. Osamawonjezera zinthu zina za alkaline kuti chisakanizo chisanachitike hydroxethyl cellulose ufa umawotchedwa m'madzi. Kukweza mtengo wa pH mutatha kutentha kudzathandiza kusungunuka. a

5. Monga momwe mungathere, onjezani wotsutsa-fungal wothandizila kuyambiranso. a

6. Makina opangidwa ndi ma hydroxyethyl nthawi zambiri sakhala osavuta kupanga zotupa kapena magawo, kapena mtundu wa mafayilo ochepa pambuyo powonjezera madzi.
