Hydroxyethyl Cellulose (HEC) ndi polima yosungunuka m'madzi yomwe imagwiritsidwa ntchito kwambiri pazinthu zosiyanasiyana chifukwa cha mawonekedwe ake apadera. HEC imachokera ku cellulose ndipo imagwiritsidwa ntchito ngati thickening, stabilizing, and rheology-modifying agent m'mafakitale osiyanasiyana.HEC ndi polima yosunthika yomwe imakhala ndi ntchito zambiri chifukwa cha katundu wake wapadera, monga kusungunuka kwa madzi, kusungunuka ndi kusungunuka. luso lokhazikika, ndi rheology-kusintha katundu. Kusinthasintha kwake komanso kugwiritsa ntchito kwake kumapangitsa kukhala chisankho chodziwika bwino m'mafakitale osiyanasiyana, kuphatikiza utoto & zokutira, chisamaliro chamunthu, zomangamanga, chakudya, mankhwala, mafuta ndi gasi, mapepala, ndi nsalu.
● Paint&Coating thickener
Utoto wa latex wokhala ndiHECchigawocho ali ndi katundu wa kusungunuka mofulumira, thovu otsika, zotsatira zabwino thickening, wabwino kukula mtundu ndi bata kwambiri. Makhalidwe ake osakhala a ionic amathandizira kukhazikika pamitundu yambiri ya pH ndikuloleza mitundu yosiyanasiyana.
Kuchita bwino kwambiri kwazinthu zotsatizana za HEC HS ndikuti hydration imatha kuwongoleredwa ndikuwonjezera chowonjezera m'madzi kumayambiriro kwa kugaya kwa pigment.
Magiredi apamwamba a viscosity a HEC HS100000, HEC HS150000 ndi HEC HS200000 amapangidwa makamaka kuti apange utoto wa latex wosungunuka m'madzi, ndipo mlingo wake ndi wocheperako kuposa zokhuthala zina.
●Ulimi
Hydroxyethyl cellulose (HEC) imatha kuyimitsa ziphe zolimba m'madzi opopera.
Kugwiritsa ntchito HEC mu ntchito yopopera kumatha kugwira ntchito yomatira poizoni pamasamba; HEC angagwiritsidwe ntchito monga thickener wa kutsitsi emulsion kuchepetsa kutengeka kutengeka wa mankhwala, potero kuwonjezera zotsatira ntchito kutsitsi foliar.
HEC itha kugwiritsidwanso ntchito ngati chopangira filimu popangira mbewu; monga chomangira pobwezeretsanso masamba a fodya.
●Zinthu zomangira
HEC ikhoza kugwiritsidwa ntchito mu gypsum, simenti, laimu ndi matope, phala ndi matope. Mu gawo la simenti, itha kugwiritsidwanso ntchito ngati cholepheretsa komanso chosungira madzi. Pochiza ntchito zapambali, zimagwiritsidwa ntchito popanga latex, yomwe imatha kuchiritsa pamwamba ndi kuchepetsa kupanikizika kwa khoma, kuti zotsatira za kujambula ndi zokutira pamwamba zikhale bwino; itha kugwiritsidwa ntchito ngati thickener kwa zomatira wallpaper.
HEC ikhoza kupititsa patsogolo ntchito ya matope a gypsum powonjezera kuumitsa ndi nthawi yogwiritsira ntchito. Pankhani ya mphamvu yopondereza, mphamvu ya torsional ndi kukhazikika kwapang'onopang'ono, HEC imakhala ndi zotsatira zabwino kuposa ma cellulose ena.
● Zodzoladzola ndi zotsukira
HEC ndi filimu yogwira ntchito kale, binder, thickener, stabilizer ndi dispersant mu shampoos, opopera tsitsi, neutralizers, conditioners ndi zodzoladzola. Kukhuthala kwake ndi chitetezo cha colloid chitha kugwiritsidwa ntchito m'mafakitale otsukira madzi ndi olimba. HEC imasungunuka mofulumira pa kutentha kwakukulu, komwe kungathe kufulumizitsa ndondomeko yopangira ndi kupititsa patsogolo kupanga. Ndizodziwika bwino kuti chinthu chodziwika bwino cha zotsukira zomwe zili ndi HEC ndikuwongolera kusalala kwa nsalu ndi mercerization.
●Latex polymerization
Kusankha HEC ndi digiri inayake molar m'malo akhoza kuimba zotsatira zabwino m'kati catalyzing ndi polymerization wa zoteteza colloids; polamulira kukula kwa tinthu ta polima, kukhazikika kwa latex ntchito, ndi kukana kutentha kochepa ndi kutentha kwakukulu, ndi kumeta makina, HEC ingagwiritsidwe ntchito. ku zotsatira zabwino. Pa polymerization wa latex, HEC angateteze ndende ya colloid mkati osiyanasiyana yovuta, ndi kulamulira kukula kwa particles polima ndi mlingo wa ufulu nawo magulu zotakasika.
●Kutulutsa mafuta
HEC ikugwira ntchito pokonza ndi kudzaza slurries. Zimathandizira kupereka matope abwino otsika olimba osawonongeka pang'ono pachitsime. Slurry wokhuthala ndi HEC amawonongeka mosavuta kukhala ma hydrocarbon ndi ma acid, ma enzymes kapena oxidants ndipo amakulitsa kuchira kwamafuta.
M'matope osweka, HEC imatha kutenga matope ndi mchenga. Madzi awa amathanso kuwonongeka mosavuta ndi ma acid, ma enzymes kapena ma oxidants omwe ali pamwambapa.
Kubowola kwamadzimadzi abwino otsika kumatha kupangidwa ndi HEC, komwe kumapereka mwayi wochulukirapo komanso kukhazikika bwino pakubowola. Makhalidwe ake osunga madzimadzi amatha kugwiritsidwa ntchito pobowola miyala yolimba komanso m'mapangidwe otsika kapena otsika.
Powonjezera simenti, HEC imachepetsa kukana kwa pore-pressure simenti slurry, potero kumachepetsa kuwonongeka kwa kapangidwe kamene kamataya madzi.
● Mapepala ndi inki
HEC itha kugwiritsidwa ntchito ngati glazing wothandizira pamapepala ndi makatoni ndi guluu zoteteza inki. HEC ili ndi ubwino wokhala wodziimira paokha pa kukula kwa pepala mu kusindikiza, ndipo ingagwiritsidwe ntchito kusindikiza zithunzi zamtengo wapatali, ndipo panthawi imodzimodziyo, ikhoza kuchepetsanso ndalama chifukwa cha kutsika kwake kochepa komanso kuwala kwamphamvu.
Itha kugwiritsidwanso ntchito papepala lililonse la kukula kapena kusindikiza kwa makatoni kapena kusindikiza kwa kalendala. Pakukula kwa pepala, mlingo wake wanthawi zonse ndi 0.5 ~ 2.0 g/m2.
HEC ikhoza kuonjezera kusungidwa kwa madzi mumitundu ya utoto, makamaka utoto wokhala ndi gawo lalikulu la latex.
Popanga mapepala, HEC ili ndi zinthu zina zapamwamba, kuphatikizapo kugwirizana ndi chingamu zambiri, utomoni ndi mchere wachilengedwe, kusungunuka kwachangu, kutsika kwa thovu, kutsika kwa oxygen komanso kuthekera kopanga filimu yosalala pamwamba.
Popanga inki, HEC imagwiritsidwa ntchito popanga ma inki opangidwa ndi madzi omwe amauma mwachangu ndikufalikira bwino popanda kumamatira.
●Kukula kwa nsalu
HEC yakhala ikugwiritsidwa ntchito poyesa ndi utoto wa ulusi ndi zinthu za nsalu, ndipo guluu amatha kutsukidwa ndi ulusi pochapa ndi madzi. Kuphatikiza ndi utomoni wina, HEC ikhoza kugwiritsidwa ntchito kwambiri pochiza nsalu, mu galasi fiber imagwiritsidwa ntchito ngati chopangira chopangira ndi binder, ndi zamkati zachikopa monga chosinthira ndi binder.
Zopaka za latex, zomatira ndi zomatira
Zomatira zokhuthala ndi HEC ndi pseudoplastic, ndiko kuti, zimakhala zoonda pansi pakumeta ubweya, koma zimabwerera mwachangu kumayendedwe apamwamba ndikuwongolera kumveka bwino kwa kusindikiza.
HEC imatha kuwongolera kutulutsidwa kwa chinyezi ndikulola kuti iziyenda mosalekeza pamtundu wa utoto popanda kuwonjezera zomatira. Kuwongolera kutulutsa madzi kumapangitsa kuti pakhale nthawi yotseguka, yomwe imakhala yopindulitsa pakusunga zodzaza ndi kupanga filimu yabwino yomatira popanda kuwonjezera nthawi yowuma.
HEC HS300 pa ndende ya 0,2% mpaka 0,5% mu njira bwino mawotchi mphamvu ya zomatira sanali nsalu, amachepetsa chonyowa kuyeretsa pa masikono chonyowa, ndi kumawonjezera chonyowa mphamvu ya chomaliza mankhwala.
HEC HS60000 ndi zomatira zabwino zosindikizira ndi kudaya nsalu zosalukidwa, ndipo zimatha kupeza zithunzi zomveka bwino, zokongola.
HEC itha kugwiritsidwa ntchito ngati chomangira cha utoto wa acrylic komanso zomatira pazopanga zopanda nsalu. Amagwiritsidwanso ntchito ngati thickener kwa zoyambira nsalu ndi zomatira. Sichichita ndi zodzaza ndipo zimakhalabe zogwira mtima pazigawo zochepa.
Kupaka utoto ndi kusindikiza makapeti ansalu
Mu utoto wa carpet, monga Kusters mosalekeza wopaka utoto, zokhuthala zina zochepa zimatha kufanana ndi kukhuthala komanso kuyanjana kwa HEC. Chifukwa cha kukhuthala kwake, imasungunuka mosavuta muzosungunulira zosiyanasiyana, ndipo zonyansa zake zochepa sizimasokoneza kuyamwa kwa utoto ndi kufalikira kwa utoto, kupanga kusindikiza ndi utoto wopanda ma gels osasungunuka (omwe angayambitse mawanga pa nsalu) ndi malire a Homogeneity zofunikira zamakono.
●Mapulogalamu ena

Electroplating ndi Electrolysis -
HEC imatha kuteteza colloid ku chikoka cha ndende ya electrolyte; hydroxyethyl mapadi amatha kulimbikitsa yunifolomu mafunsidwe mu cadmium electroplating njira.
Ceramics -
Itha kugwiritsidwa ntchito kupanga zomangira zolimba kwambiri zama ceramic.
Chingwe—
