Hydroxyethyl cellulose (HEC) ndi yoyera kapena yopepuka yachikasu, yopanda fungo, yopanda poizoni kapena yolimba, yomwe imakonzedwa ndi etherification ya alkaline cellulose ndi ethylene oxide (kapena chlorohydrin).Nonionic soluble cellulose ethers.Popeza HEC ili ndi katundu wabwino wa thickening, kuyimitsa, kumwazikana, emulsifying, kugwirizana, kupanga mafilimu, kuteteza chinyezi ndi kupereka colloid zoteteza, zakhala zikugwiritsidwa ntchito kwambiri pofufuza mafuta, zokutira, zomangamanga, mankhwala, chakudya, nsalu, kupanga mapepala ndi polymerization. ndi minda ina.40 mauna sieving mlingo ≥ 99%;
Maonekedwe: zoyera mpaka zachikasu zobiriwira kapena zolimba, zopanda poizoni, zopanda kukoma, zosungunuka m'madzi.Insoluble mu wamba organic solvents.
Hydroxyethyl cellulosethickener
Kukhuthala kumasintha pang'ono mumtundu wa PH mtengo 2-12, koma kukhuthala kumachepera kuposa izi.Lili ndi katundu wa thickening, kuyimitsa, kumanga, emulsifying, dispersing, kusunga chinyezi ndi kuteteza colloid.Mayankho osiyanasiyana mamasukidwe akayendedwe osiyanasiyana akhoza kukonzekera.Kusakhazikika pansi pa kutentha kwabwino ndi kupanikizika, kupewa chinyezi, kutentha, ndi kutentha kwakukulu, komanso kukhala ndi mchere wabwino kwambiri wa dielectrics, ndipo njira yake yamadzimadzi imalola kuti mchere wambiri ukhale wokhazikika.
Zofunikira:
Monga si ionic surfactant, hydroxyethyl cellulose ili ndi zinthu zotsatirazi kuwonjezera pa kukhuthala, kuyimitsa, kumanga, kuyandama, kupanga mafilimu, kubalalitsa, kusunga madzi ndi kupereka colloid yoteteza:
1. HEC imasungunuka m'madzi otentha kapena madzi ozizira, ndipo sichimawotcha kutentha kwambiri kapena kutentha, kotero kuti imakhala ndi mitundu yambiri ya solubility ndi viscosity, ndi gelation yopanda kutentha;
2. Siionic ndipo imatha kukhala limodzi ndi ma polima ena osungunuka m'madzi, ma surfactants, ndi mchere.Ndibwino kwambiri colloidal thickener kwa high-concentration electrolyte solutions;
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.
Malo ogwiritsira ntchito
Amagwiritsidwa ntchito ngati zomatira, surfactant, colloidal zoteteza wothandizila, dispersant, emulsifier ndi dispersion stabilizer, etc. Iwo ali osiyanasiyana ntchito mu minda ya zokutira, inki, ulusi, utoto, papermaking, zodzoladzola, mankhwala, mchere processing, mafuta m'zigawo ndi mankhwala.
1. Nthawi zambiri amagwiritsidwa ntchito ngati thickener, zotetezera, zomatira, stabilizer, ndi zowonjezera pokonzekera emulsions, jellies, mafuta odzola, odzola, oyeretsa maso, suppositories, ndi mapiritsi.Amagwiritsidwanso ntchito ngati gel osakaniza a hydrophilic ndi skeleton Materials, kukonzekera matrix-mtundu wokhazikika wokonzekera, komanso angagwiritsidwe ntchito ngati chokhazikika muzakudya.
2. Amagwiritsidwa ntchito ngati sizing wothandizila mu makampani nsalu, ndi ngati wothandizira wothandiza kwa bonding, thickening, emulsifying, ndi kukhazikika mu zamagetsi ndi kuwala makampani makampani.
3. Amagwiritsidwa ntchito ngati thickener ndi kutaya madzimadzi kutaya reducer kwa madzi pobowola madzimadzi ndi kumaliza madzimadzi, ndi thickening zotsatira zoonekeratu mu brine pobowola madzimadzi.Itha kugwiritsidwanso ntchito ngati chochepetsera kutaya madzi kwa simenti yamafuta bwino.Itha kulumikizidwa ndi ayoni azitsulo a polyvalent kuti apange gel.
4. Mankhwalawa amagwiritsidwa ntchito ngati dispersant kwa polymerization ya mafuta a petroleum madzi ofotokoza gel osakaniza fracturing madzimadzi, polystyrene ndi polyvinyl kolorayidi, etc. ndi fracturing.Itha kugwiritsidwanso ntchito ngati emulsion thickener mumakampani opanga utoto, hygrostat mumakampani amagetsi, anticoagulant ya simenti ndi chosungira chinyezi pantchito yomanga.Ceramic industry glazing ndi mankhwala otsukira mano binder.Amagwiritsidwanso ntchito kwambiri posindikiza ndi kudaya, nsalu, kupanga mapepala, mankhwala, ukhondo, chakudya, ndudu, mankhwala ophera tizilombo ndi zozimitsa moto.
5. Monga surfactant, colloidal zoteteza wothandizira, emulsification stabilizer kwa vinilu kolorayidi, vinilu acetate ndi emulsions ena, komanso latex tackifier, dispersant, dispersion stabilizer, etc. Amagwiritsidwa ntchito kwambiri mu zokutira, ulusi, utoto, papermaking, zodzoladzola, mankhwala, mankhwala, mankhwala, mankhwala, , etc. Lilinso ndi ntchito zambiri mu kufufuza mafuta ndi makampani makina.
6. Hydroxyethyl cellulose imakhala ndi ntchito yogwira ntchito, yowonjezera, yoyimitsa, yomangiriza, emulsifying, kupanga mafilimu, kufalitsa, kusunga madzi ndi ntchito zotetezera mu mankhwala olimba ndi amadzimadzi.
7. Amagwiritsidwa ntchito ngati dispersant polymeric pogwiritsira ntchito mafuta a petroleum madzi opangidwa ndi gel fracturing fluid, polyvinyl chloride ndi polystyrene.Angagwiritsidwenso ntchito ngati emulsion thickener mu makampani utoto, simenti anticoagulant ndi chinyezi posungira wothandizila mu zomangamanga, wothandizila glazing ndi zomatira otsukira m`kamwa mu makampani ceramic.Amagwiritsidwanso ntchito kwambiri m'mafakitale monga kusindikiza ndi utoto, nsalu, kupanga mapepala, mankhwala, ukhondo, chakudya, ndudu ndi mankhwala ophera tizilombo.
Magwiridwe Azinthu
1. HEC imasungunuka m'madzi otentha kapena madzi ozizira, ndipo sichimawotcha kutentha kwambiri kapena kutentha, kotero kuti imakhala ndi mitundu yambiri ya solubility ndi viscosity, ndi gelation yopanda kutentha;
