Utoto, mwambo wotchedwa utoto ku China. Utoto wotchedwa utoto umakhala pamwamba pa chinthu kuti chitetezedwe kapena kukongoletsedwa, ndipo chingapangitse filimu yopitilira muyeso yolumikizidwa ndi chinthu kuti chikhale cholumikizidwa.
Kodi hydroxyethyl ndi chiyani cellulose?
Hydroxyethyl cellulose (hec), chikasu chachikaso kapena chowoneka bwino, chosawoneka bwino, chokhazikika ndi cylylene oxide), amakhala a cellulose yosungunuka m'malo a cellulose. Popeza Hec ali ndi katundu wabwino, kuyimitsa, kubalalitsa, kuphatikizika, kulumikizana, kupanga chinyezi, chakudya, zojambulajambula ndi polymerization ndi minda ina.
Kodi chimachitika ndi chiyani pamene hydroxyethyl cellose yokumana ndi utoto wozikidwa m'madzi?
Monga osagwirizana ndi ionic, hydroxethyl cellulose ili ndi zotsatirazi kuwonjezera, kuyimitsa, kuyandama, kukonza mafilimu,
Hec amasungunuka m'madzi otentha kapena madzi ozizira, kutentha kwambiri kapena kuwira popanda mpweya, kotero kuti ili ndi mawonekedwe osiyanasiyana komanso owoneka bwino;
Kuchuluka kwa madzi ndikokwera kwambiri ngati kwa methyl cellulose, ndipo imakhala ndi malamulo owuma;
Poyerekeza ndi methyl cellose ndi hydroxypropyl methy celyolose, kuthekera kwa hec ndiye choyipa kwambiri, koma kuthekera kotchinjiriza ndikolimba.
Siyopanda ionic ndipo imatha kukhala yolumikizana ndi ma pointer ena osungunuka madzi, okonda, ndi mchere. Ndibwino kwambiri colloidal yothetsera mavuto ambiri a electrolyte;
Momwe mungagwiritsire ntchito hydroxyethyl cellulose? Momwe mungawonjezere?
Onjezani mwachindunji pakupanga - njirayi ndiyosavuta kwambiri ndipo imatenga nthawi yochepa kwambiri.
Onjezani madzi oyera ku chidebe chachikulu chokhala ndi chosakanizira chachikulu. Yambani kukweza mosalekeza mwachangu ndikung'amba pang'onopang'ono hydroththyl cellulose poyankha. Pitilizani kusokoneza mpaka tinthu tating'onoting'ono titanyowa. Kenako onjezerani oteteza komanso zowonjezera zosiyanasiyana. Monga utoto, wobalalitsa Edzi, madzi ammoni, etc. Khazikitsani mpaka pa cellulose yonse imasungunuka kwambiri.
Okonzeka ndi amayi
Ndikukonzekera mayi mowa ndi kuchuluka kwambiri poyamba, kenako kuwonjezera pazogulitsa. 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 andichitikire okalamba kwambiri, ndipo okhawo omwe ali ndi mphamvu zokwanira kuti asunge ma hydroxethyl cellulose omwe amafalitsidwa mu yankho atha kupitilizidwa popanda kunyamuka. Komabe, ziyenera kudziwika kuti funguyi ayenera kuwonjezeredwa kwa amayi omwe amamwa mowa msanga.
Popeza ma hydroxyethyl opaleshoni ndi powdery kapena fibruus cholimba, lihongdeddes amakumbutsa kuti musangalale ndi mfundo zotsatirazi pokonzekera ma hydroxyethyl mowa wamagetsi:

. Kukweza PH pambuyo ponyowa kumathandiza kusungunuka.
(5) Monga momwe mungathere, onjezani antifungal wothandizira pasadakhale
