Hydroxyethyl cellulose (HEC) ndi yoyera kapena yopepuka yachikasu, yopanda fungo, yopanda poizoni kapena yolimba yaufa yokonzedwa ndi etherification ya cellulose yamchere ndi ethylene oxide (kapena chlorohydrin).Nonionic soluble cellulose ethers.Chifukwa HEC ili ndi katundu wabwino monga thickening, kuyimitsa, kubalalika, emulsifying, kugwirizana, filimu kupanga, kuteteza chinyezi ndi kupereka colloids zoteteza, wakhala ankagwiritsa ntchito pa khungu chisamaliro , kufufuza mafuta, zokutira, zomangamanga, mankhwala ndi chakudya, nsalu, kupanga mapepala ndi ma polima.Polymerization ndi magawo ena.40 mauna sieving mlingo ≥ 99%;
Mawonekedwe: zoyera mpaka zachikasu zobiriwira kapena zolimba, zopanda poizoni, zopanda fungo, zimasungunuka mosavuta m'madzi.Insoluble zambiri organic solvents.
Hydroxyethyl cellulose
Pakati pa mtengo wa PH wa 2-12, kusintha kwa viscosity kumakhala kochepa, koma kukhuthala kumachepa kuposa izi.Lili ndi katundu wa thickening, kuyimitsa, kugwirizana, emulsifying, dispersing, kusunga chinyezi ndi kuteteza colloid.Mayankho amitundu yosiyanasiyana yama viscosity akhoza kukonzedwa.Ndi yosakhazikika pansi pa kutentha kwabwino ndi kupanikizika, kupewa chinyezi, kutentha ndi kutentha kwakukulu, ndipo imakhala ndi mchere wabwino kwambiri wosungunuka kwa ma dielectrics, ndipo njira yake yamadzimadzi imaloledwa kukhala ndi mchere wambiri ndipo imakhala yokhazikika.
Zofunika: Monga osakhala ionic surfactant, hydroxyethyl cellulose ili ndi zinthu zotsatirazi kuwonjezera pa thickening, kuyimitsa, kumanga, kuyandama, kupanga mafilimu, kubalalika, kusunga madzi ndi kupereka colloids zoteteza:
1. HEC imasungunuka m'madzi otentha kapena ozizira, ndipo sichitha kutentha kwambiri kapena kutentha, kumapangitsa kuti ikhale ndi mitundu yambiri ya solubility ndi viscosity, ndi gelation yopanda kutentha;
2. Ndizopanda ma ionic ndipo zimatha kukhala pamodzi ndi ma polima ena osungunuka m'madzi, ma surfactants ndi mchere, ndipo ndi abwino kwambiri a colloidal thickener omwe ali ndi ma electrolyte 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 colloid yotetezera imakhala ndi mphamvu zolimba kwambiri.
Kupinda kwa malo ogwiritsira ntchito
Amagwiritsidwa ntchito ngati zomatira, surfactant, colloid zoteteza wothandizila, dispersant, emulsifier ndi dispersion stabilizer.Lili ndi ntchito zosiyanasiyana zopangira zokutira, inki, ulusi, utoto, kupanga mapepala, zodzoladzola, mankhwala ophera tizilombo, kukonza mchere, kuchotsa mafuta ndi mankhwala.
1. Amagwiritsidwa ntchito ngati thickening wothandizila, zoteteza wothandizila, zomatira, stabilizer ndi zowonjezera pokonzekera emulsion, gel osakaniza, mafuta, odzola, diso kuyeretsa wothandizila, suppository ndi piritsi, amagwiritsidwanso ntchito monga hydrophilic gel osakaniza, mafupa zipangizo, kukonzekera mafupa opitiriza-kumasulidwa kukonzekera. , ndipo angagwiritsidwenso ntchito ngati stabilizer mu chakudya.

4. Izi zimagwiritsidwa ntchito ngati dispersant kwa madzi opangidwa ndi gel osakaniza fracturing madzi, polystyrene ndi polyvinyl kolorayidi mu mafuta fracturing kupanga.Itha kugwiritsidwanso ntchito ngati emulsion thickener m'makampani opaka utoto, chinyezi tcheru resistor mumakampani amagetsi, simenti coagulation inhibitor ndi wosungira chinyezi pantchito yomanga.Zomatira zowuma ndi zotsukira mano zamakampani a ceramic.Amagwiritsidwanso ntchito kwambiri posindikiza ndi kudaya, nsalu, kupanga mapepala, mankhwala, ukhondo, chakudya, ndudu, mankhwala ophera tizilombo ndi zozimitsa moto.
5. Ntchito ngati surfactant, colloid zoteteza wothandizila, emulsion 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 ophera tizilombo, ndi zina zotero. Lilinso ndi ntchito zambiri m'mafakitale ochotsa mafuta ndi makina.
6. Hydroxyethyl cellulose imakhala ndi ntchito yapamwamba, yowonjezera, kuyimitsa, kumanga, emulsifying, kupanga mafilimu, kufalitsa, kusunga madzi ndi kupereka chitetezo pakukonzekera mankhwala olimba ndi madzi.
7. Amagwiritsidwa ntchito ngati dispersant chifukwa masuku pamutu mafuta a petroleum madzi gel osakaniza fracturing madzi, polyvinyl kolorayidi ndi polystyrene.Itha kugwiritsidwanso ntchito ngati emulsion thickener mumakampani opanga utoto, simenti coagulation inhibitor ndi wosungira chinyezi pantchito yomanga, glazing wothandizila ndi zomatira zotsukira m'mano m'makampani a ceramic.Amagwiritsidwanso ntchito kwambiri posindikiza ndi kudaya, nsalu, kupanga mapepala, mankhwala, ukhondo, chakudya, ndudu ndi mankhwala ophera tizilombo ndi minda ina yamakampani.
Kupinda kwapang'onopang'ono kwazinthu
1. HEC imasungunuka m'madzi otentha kapena ozizira, ndipo sichitha kutentha kwambiri kapena kutentha, kotero kuti imakhala ndi mitundu yambiri ya solubility ndi viscosity, ndi gelation yopanda kutentha;
2. Zopanda ma ionic zokha zimatha kukhala pamodzi ndi ma polima ena osungunuka m'madzi, ma surfactants ndi mchere, ndipo ndi colloidal thickener yabwino kwambiri yomwe ili ndi ma dielectric 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 colloid yotetezera imakhala ndi mphamvu zolimba kwambiri.
Momwe mungapindane
Lowani mwachindunji kupanga
1. Thirani madzi oyera pachidebe chachikulu chokhala ndi chosakaniza chometa ubweya wambiri.
2. Yambani kuyambitsa mosalekeza pa liwiro lotsika ndikusefa pang'onopang'ono cellulose ya hydroxyethyl mu yankho mofanana.
3. Pitirizani kuyambitsa mpaka tinthu tating'onoting'ono tanyowa.
4. Kenaka yikani antifungal wothandizira, zowonjezera zamchere monga ma pigment, dispersing aids, ammonia madzi.
5. Onetsetsani mpaka cellulose yonse ya hydroxyethyl itasungunuka kwathunthu (kukhuthala kwa yankho kumawonjezeka kwambiri) musanawonjezere zigawo zina mu ndondomeko, ndikupera mpaka mankhwala omalizidwa.
Udindo wa hydroxyethyl cellulose pakupanga mankhwala odzola?Ma polima osungunuka m'madzi omwe amagwiritsidwa ntchito pazodzikongoletsera amagawidwa m'magulu awiri: zachilengedwe komanso zopangidwa.
Mankhwala achilengedwe a polima osungunuka m'madzi akuphatikizapo: wowuma, chingamu cha zomera, gelatin ya nyama, ndi zina zotero, koma khalidweli ndi losakhazikika, limakhudzidwa mosavuta ndi nyengo, malo okhala, zokolola zochepa, ndipo zimawonongeka mosavuta ndi mabakiteriya ndi nkhungu.
Mankhwala opangidwa ndi polima osungunuka m'madzi amaphatikizapo mowa wa polyvinyl, polyvinylpyrrolidone, ndi zina zotero, zomwe zimakhala ndi katundu wokhazikika, kupsa mtima kwapakhungu komanso mtengo wotsika, kotero alowa m'malo mwazinthu zachilengedwe zosungunuka m'madzi ndikukhala gwero lalikulu la zopangira za colloid.
Imagawidwanso mu semi-synthetic ndi kupanga polima zosungunuka m'madzi.
Semi-synthetic water-soluble polymer compounds amagwiritsidwa ntchito nthawi zambiri: methyl cellulose, ethyl cellulose, sodium carboxymethyl cellulose, hydroxyethyl cellulose, ndi guar gum ndi zotumphukira zake.
Mankhwala opangidwa ndi polima osungunuka m'madzi amagwiritsidwa ntchito kwambiri: mowa wa polyvinyl, polyvinylpyrrolidone, acrylic acid polima, ndi zina.
Izi zimagwiritsidwa ntchito muzodzoladzola monga zomatira, zokometsera, zopangira mafilimu, ndi zolimbitsa thupi za emulsion.
