Kugwiritsa kwa hydroxyethyl cellulose mu zokutira

Utoto, mwambo wotchedwa utoto ku China. Wotchedwa kuti wokutidwayo umakhala pamwamba pa chinthu kuti atetezedwe kapena kukongoletsedwa, ndipo amatha kupanga filimu yopitilira yomwe imalumikizidwa ndi chinthu chomwe chimaphatikizidwa ndi chinthu chomwe chimaphatikizidwa.

Kodi hydroxyethyl ndi chiyani cellulose?

Hydroxyethyl cellulose (hec), chikasu chachikaso kapena chikaso, chosawoneka bwino, chokhazikika ndi ma celloude oxide), kukhala mu genlohydrin), kukhala mu genloydric sollose yosungunuka ears. Chifukwa Hec ali ndi zinthu zabwino zokukula, kuyimitsa, kubalalitsa, kulumikizidwa, kulumikizana, kupanga chinyezi, kapangidwe, kapangidwe kake ndi chakudya. Polymerization ndi minda ina.

Kodi chimachitika ndi chiani pamene ma hydroxyethyl cellulose akumana ndi zokutira zamadzi?

Monga osagwirizana ndi ionic, hydroxethyl cellulose ili ndi zotsatirazi kuwonjezera, kuyimitsa, kumangiriza, kusunthika, kusungitsa mafilimu ndikupanga zoteteza:

Hec amasungunuka m'madzi otentha kapena ozizira, ndipo osayendetsa kutentha kwambiri kapena kuwira, kuwononga, ndikupanga mawonekedwe osiyanasiyana, komanso kuphatikizira mafuta;

Kuchuluka kwa madzi ndi kawiri konse kwa methyl cellulose, ndipo ili ndi malamulo owuma;

Poyerekeza ndi methyl cellose ndi hydroxypypyl methy celyolose, kuthekera kwa hec ndiye choyipa kwambiri, koma luso loteteza lapangidwe ndi lamphamvu;

Siyopanda ionic ndipo imatha kukhala yolumikizana ndi ma pointer ena osungunuka madzi, okonda, ndi mchere. Ndibwino kwambiri cololodal yothetsera mavuto ambiri a electrolyte.

Momwe mungagwiritsire ntchito hydroxyethyl cellulose? Momwe mungawonjezere?

Onjezani mwachindunji panthawi yopanga - njirayi ndiyosavuta ndipo imatenga nthawi yochepa.

Onjezani madzi oyera ku vat omwe ali ndi duwa lalitali kwambiri. Yambitsani chisangalalo mosalekeza mwachangu ndikudumphira pang'onopang'ono hydroththyl cellulose yothetsera yankho. Pitilizani kusangalatsa mpaka tinthu tating'onoting'ono tanyowa. Kenako onjezerani oteteza komanso zowonjezera zosiyanasiyana. Monga utoto, wobalalitsa Edzi, madzi ammoni, etc. Khazikitsani mpaka pa cellulose yonse imasungunuka kwambiri.

Okonzeka ndi amayi mowa.

Ndikukonzera amayi mowa ndi mkulu wambiri, kenako ndikuwonjezera malonda. Ubwino wa njirayi ndikuti umasinthasintha kwambiri ndipo amatha kuwonjezeredwa mwachindunji kwa chinthu chomalizidwa, koma ziyenera kusungidwa bwino. Njira za njirayi ndizofanana ndi masitepe ambiri mu njira 1; Kusiyanako ndikuti palibe chifukwa choti akakamizidwe kwambiri, ndipo okhawo omwe ali ndi mphamvu zokwanira kuti asunge ma hydroxethyl cellulose cellulose moyenera mu yankho kungayambike mpaka kusungunuka kwathunthu kukhala yankho la ma viscous. Komabe, ziyenera kudziwika kuti antifural wothandizirana ayenera kuwonjezeredwa kwa amayi omwe amamwa mowa msanga.

Popeza ma hydroxyethyl cellose ndi ufa kapena shandom heda imakumbutsa kuti musangalale ndi mfundo zotsatirazi pokonzekera mafoni a hydroxyathyl mowa:

. Kukweza PH pokhapokha kunyowa kungathandize kusungunuka.
(5) Monga momwe mungathere, onjezani antifungal wothandizira pasadakhale.
