Udindo wa hydroxyethyl cellulose (HEC) mu zokutira!

Hydroxyethyl cellulose (HEC), yoyera kapena yopepuka yachikasu, yopanda fungo, yopanda poizoni kapena yolimba, yokonzedwa ndi etherification ya cellulose yamchere ndi ethylene oxide (kapena chlorohydrin), yamtundu wa Nonionic soluble cellulose ethers. Chifukwa HEC ili ndi katundu wabwino wa thickening, kuyimitsa, kumwazikana, emulsifying, kugwirizana, kupanga mafilimu, kuteteza chinyezi ndi kupereka colloids zotetezera, zakhala zikugwiritsidwa ntchito kwambiri pofufuza mafuta, zokutira, zomangamanga, mankhwala ndi chakudya, nsalu, mapepala ndi ma polima. Polymerization ndi magawo ena.

Pambuyo pa hydroxyethyl cellulose ikukumana ndi utoto wopangidwa ndi madzi?

Monga si ionic surfactant, hydroxyethyl cellulose ili ndi zotsatirazi kuwonjezera pa thickening, kuyimitsa, kumanga, kuyandama, kupanga mafilimu, kubalalika, kusunga madzi ndi kupereka colloids zoteteza:

HEC imasungunuka m'madzi otentha kapena ozizira, ndipo sichimawotcha kutentha kwambiri kapena kutentha, kumapangitsa kuti ikhale ndi mitundu yambiri ya solubility ndi viscosity, komanso gelling yopanda kutentha;

Mphamvu yosungira madzi imakhala yowirikiza kawiri ya methyl cellulose, ndipo imakhala ndi malamulo oyendetsera bwino;

Poyerekeza ndi methyl cellulose yodziwika bwino ndi hydroxypropyl methyl cellulose, kuthekera kobalalika kwa HEC ndikoyipa kwambiri, koma luso loteteza la colloid ndilolimba kwambiri;

Si ionic ndipo imatha kukhala limodzi ndi ma polima ena osungunuka m'madzi, ma surfactants, ndi mchere. Ndiwothira bwino kwambiri wa colloidal pamayankho a electrolyte apamwamba kwambiri.

Momwe mungagwiritsire ntchito hydroxyethyl cellulose?

Onjezani mwachindunji panthawi yopanga - njirayi ndi yosavuta komanso imatenga nthawi yochepa:

Yambani kugwedeza mosalekeza pa liwiro lotsika ndipo pang'onopang'ono sefa hydroxyethyl cellulose mofanana mu yankho ndikupitiriza kusonkhezera mpaka tinthu tating'onoting'ono tanyowa. Kenaka yikani zotetezera ndi zina zowonjezera. Monga inki, dispersing zothandizira, ammonia, etc. Muziganiza mpaka onse hydroxyethyl mapadi ndi kusungunuka kwathunthu (kukhuthala kwa kukhuthala kwa yankho kumawonjezera kwambiri) pamaso kuwonjezera zigawo zina mu chilinganizo kuchita anachita.

Okonzeka ndi chakumwa cha mayi

Ndiko kukonzekera mowa wa mayi wokhala ndi ndende yapamwamba poyamba, kenako ndikuwonjezera ku mankhwalawo. Ubwino wa njirayi ndikuti umakhala ndi kusinthasintha kwakukulu ndipo ukhoza kuwonjezeredwa mwachindunji ku mankhwala omalizidwa, koma ayenera kusungidwa bwino. Masitepe a njirayi ndi ofanana ndi masitepe ambiri mu Njira 1; kusiyana ndi kuti palibe chifukwa mkulu-kumeta ubweya agitator, ndi ena agitators ndi mphamvu zokwanira kusunga mapadi hydroxyethyl uniformly omwazika mu yankho angagwiritsidwe ntchito, ndi kupitiriza Kusonkhezera mpaka kwathunthu kusungunuka mu njira viscous. Komabe, ziyenera kudziwidwa kuti antifungal wothandizira ayenera kuwonjezeredwa kwa mowa wamayi posachedwa.

Malangizo abwino:

Popeza kuti mankhwala a hydroxyethyl cellulose ndi powdery kapena fibrous solid, pokonzekera mowa wa hydroxyethyl cellulose, akukumbutseni kuti mumvetsere mfundo zotsatirazi:

Isanayambe kapena itatha kuwonjezera pa cellulose ya hydroxyethyl, iyenera kugwedezeka mpaka yankho likuwonekera bwino komanso lomveka bwino;

Izo ziyenera sieved mu kusanganikirana mbiya pang`onopang`ono, ndipo musati mwachindunji kulumikiza apezeka kapena spheroids ndi hydroxyethyl mapadi mu kusakaniza mbiya;

Kutentha kwa madzi ndi pH ya madzi kumakhala ndi ubale wofunikira ndi kusungunuka kwa cellulose ya hydroxyethyl, kotero chidwi chapadera chiyenera kuperekedwa kwa izo;

Osawonjezera zinthu zamchere kusakaniza pamaso pahydroxyethyl celluloseufa wanyowa ndi madzi. Kukweza pH mtengo mutatha kuvina kumathandizira kusungunuka;

Momwe mungathere, onjezerani antifungal wothandizira pasadakhale;

Pamene ntchito mkulu mamasukidwe akayendedwe mapadi hydroxyethyl mapadi, ndende ya mowa mayi sayenera kupitirira 2.5-3% (ndi kulemera), apo ayi mowa mayi n`kovuta kupirira.
