Ma cellulose a Hydroxyethyl omwe amagwiritsidwa ntchito mu zodzoladzola

Mu zodzoladzola, pali zinthu zambiri zopanda mtundu komanso zopanda fungo, koma zopanda poizoni. Lero ndikudziwitsanihydroxyethyl cellulose, zomwe zimakonda kwambiri zodzoladzola zambiri kapena zofunika zatsiku ndi tsiku.

Hydroxyethyl cellulose

Imadziwikanso kuti (HEC) ndi yoyera kapena yopepuka yachikasu, yopanda fungo, yopanda poizoni kapena yolimba. Chifukwa cha makhalidwe ake abwino a thickening, kuyimitsa, kufalitsa, emulsifying, kumamatira, kupanga mafilimu, kuteteza chinyezi ndi kupereka colloid yotetezera, HEC yakhala ikugwiritsidwa ntchito kwambiri m'madera azachipatala ndi zodzoladzola.

Zogulitsa Zamalonda

1. HEC imasungunuka m'madzi otentha kapena madzi ozizira, kutentha kwakukulu kapena kuwira popanda mvula, kotero kuti imakhala ndi mitundu yambiri ya solubility ndi viscosity, ndi gelation yopanda kutentha;

2. Ndizopanda ionic ndipo zimatha kukhala pamodzi ndi ma polima ena osungunuka m'madzi, ma surfactants ndi mchere wambiri. Ndicolloidal thickener yabwino kwambiri yothetsera mayankho omwe ali ndi ma dielectrics apamwamba kwambiri;

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

4. Poyerekeza ndi methyl cellulose yodziwika bwino ndi hydroxypropyl methyl cellulose, mphamvu yobalalika ya HEC ndiyoipa kwambiri, koma mphamvu yoteteza colloid ndiyo yamphamvu kwambiri.

Rolepa HECmu zodzoladzola

Kulemera kwa maselo mu zodzoladzola, kachulukidwe ka zinthu monga zopangira zachilengedwe ndi zopangira zopangira ndizosiyana, choncho m'pofunika kuwonjezera solubilizer kuti zosakaniza zonse ziziyenda bwino. The solubility ndi mamasukidwe akayendedwe katundu wa hydroxyethyl mapadi mokwanira mbali, ndi kukhalabe bwino khalidwe, kotero kuti kukhalabe mawonekedwe oyambirira zodzoladzola mu nyengo alternating ozizira ndi otentha. Kuphatikiza apo, imakhala ndi zinthu zonyowa ndipo nthawi zambiri imapezeka muzodzoladzola zopangira zonyowa. Makamaka masks, toner, etc. pafupifupi onse anawonjezera.

Ntchitozotsatira

Ma cellulose a Hydroxyethyl omwe amagwiritsidwa ntchito mu zodzoladzola monga emollients, thickeners, etc. kwenikweni alibe poizoni. Ndipo imatengedwa ngati No. 1 chilengedwe chitetezo mankhwala ndi EWG.
