Hydroxyethyl Cellulose (HEC)
Hydroxyethyl cellulose(HEC)
CAS:9004-62-0
Hydroxyethyl cellulose(HEC) ndi ether ya cellulose yosungunuka m'madzi yopanda ionic, yomwe imagwiritsidwa ntchito ngati chokhuthala, choteteza colloid, chothandizira kusunga madzi komanso chosinthira rheology m'njira zosiyanasiyana monga utoto wochokera m'madzi, zipangizo zomangira, mankhwala ophera mafuta ndi zinthu zosamalira thupi. Chifukwa cha makhalidwe ake apadera, monga kukhuthala kwakukulu, kusungunuka m'madzi otentha ndi ozizira, komanso kukhazikika kwa mankhwala, HEC ndi chinthu chofunikira kwambiri m'mafakitale ambiri ndi ogula.
HEC imapangidwa poika magulu a hydroxyethyl (-CH₂CH₂OH) mu unyolo wa polymer wa cellulose kudzera mu etherification reaction. Kusintha kumeneku kumawonjezera kusungunuka kwa madzi, mphamvu yake yokhuthala, komanso kugwirizana ndi mitundu yosiyanasiyana.

| Zomatira | Zomatira zapakhomo zomatira za latex Zomatira za plywood | Kukhuthala ndi kukhuthala Kukhuthala ndi kumangirira madzi Kukhuthala ndi kukhazikika kwa zinthu zolimba |
| Zomangira | Ndodo zowotcherera Chophimba cha Ceramic Mizere ya Foundry | Chithandizo chomangirira madzi ndi kutulutsa madzi Kumangirira madzi ndi mphamvu yobiriwira Kumanga madzi |
| Utoto | utoto wa latex Utoto wa kapangidwe kake | Kukhuthala ndi kuteteza colloid Kumanga madzi |
| Zodzoladzola & chotsukira | Zodzola tsitsi Mankhwala otsukira mano sopo wamadzimadzi ndi bafa losambira, mafuta odzola ndi mafuta odzola m'manja | Kukhuthala Kukhuthala Kukhazikika Kukhuthala ndi kukhazikika |
Ubwino Waukulu:
1. Kusunga Madzi Bwino: Kumathandiza kupewa kuumitsa msanga zinthu zopangidwa ndi simenti ndi zodzoladzola.
2. Yokhazikika pa pH yochuluka: Imakhalabe yogwira ntchito m'malo okhala ndi acidity, neutral, komanso alkaline.
3. Yosakhala ya Ionic ndipo Imagwirizana: Imagwira ntchito bwino ndi mankhwala osiyanasiyana, kuphatikizapo mchere, ma surfactants, ndi ma polima ena.
4. Zimawonjezera Magwiridwe Abwino a Zinthu: Zimawonjezera makulidwe, kumatira, kupanga filimu, komanso mphamvu zopanga emulsification.
5. Yogwirizana ndi chilengedwe komanso yowola: Yochokera ku cellulose, HEC si poizoni ndipo imatha kuwola.
6. Imawongolera Rheology ndi Mayendedwe: Imalola kukhuthala kolamulidwa, kupewa kutsika, kutsika, ndi kulekanitsidwa kwa gawo.
Kupaka:
Chogulitsa cha HEC chili m'thumba la mapepala atatu okhala ndi thumba lamkati la polyethylene lolimbikitsidwa, kulemera konse ndi 25kg pa thumba lililonse.
Malo Osungira:
Sungani m'nyumba yosungiramo zinthu zozizira komanso zouma, kutali ndi chinyezi, dzuwa, moto, kapena mvula.
KIMA Chemical Co., Ltd. ndi wopanga akatswiri omwe amagwira ntchito yopanga ma ether a cellulose, kuphatikiza HydroxyethylSelosi(HEC). Pokhala ndi mphamvu yopangira matani 20,000 pachaka, KIMA Chemical imapereka zinthu zosiyanasiyana za HEC zapamwamba pansi pa dzina la KimaCell®, zomwe zimatumikira mafakitale osiyanasiyana monga zomangamanga, utoto ndi zokutira, mankhwala, ndi chisamaliro chaumwini.
