Cellulose, hydroxyethyl ether (MW 1000000)

Hydroxyethyl cellulose(HEC) ndi polima yosungunuka m'madzi yochokera ku cellulose poyambitsa magulu a hydroxyethyl. Kulemera kwa mamolekyulu (MW) otchulidwa, 1000000, kumayimira kusiyanasiyana kolemera kwa mamolekyu. Nayi chithunzithunzi cha cellulose ya hydroxyethyl yokhala ndi molekyulu yolemera 1000000:

Ma cellulose a Hydroxyethyl (HEC):

1. Kapangidwe ka Chemical:
   • HEC ndi chochokera ku cellulose pomwe magulu a hydroxyethyl amalumikizidwa ku mayunitsi a anhydroglucose a unyolo wa cellulose. Kusintha kumeneku kumawonjezera kusungunuka kwamadzi ndi zina zogwira ntchito za cellulose.
2. Kulemera kwa Molecular:
   • Kulemera kwa mamolekyu otchulidwa 1000000 kumasonyeza kusiyana kwakukulu kwa molekyulu. Kulemera kwa mamolekyulu kumakhudza kukhuthala, mawonekedwe a rheological, ndi magwiridwe antchito a HEC m'njira zosiyanasiyana.
3. Mawonekedwe Athupi:
   • Ma cellulose a Hydroxyethyl okhala ndi mamolekyu olemera a 1000000 amapezeka mu mawonekedwe a ufa woyera mpaka woyera, wopanda fungo. Itha kuperekedwanso ngati njira yamadzimadzi kapena kubalalitsidwa.
4. Kusungunuka kwamadzi:
   • HEC imasungunuka m'madzi ndipo imatha kupanga njira zomveka bwino komanso zowoneka bwino m'madzi. Kuchuluka kwa solubility ndi viscosity kumatha kutengera zinthu monga kutentha, pH, ndi kukhazikika.
5. Mapulogalamu:
   • Thickening Agent: HEC imagwiritsidwa ntchito kwambiri ngati chowonjezera pamitundu yosiyanasiyana, kuphatikiza utoto, zokutira, zomatira, ndi zinthu zosamalira anthu. Kusiyanitsa kwakukulu kwa maselo ndikothandiza kwambiri popereka mamasukidwe akayendedwe.
   • Stabilizer: Imagwira ntchito ngati stabilizer mu emulsions ndi suspensions, zomwe zimathandizira kukhazikika komanso kufanana kwa mapangidwewo.
   • Wothandizira Kusunga Madzi: HEC ili ndi zinthu zabwino kwambiri zosungira madzi, zomwe zimapangitsa kuti zikhale zofunika kwambiri pazomangira, monga matope ndi zinthu zopangidwa ndi simenti.
   • Mankhwala: M'makampani opanga mankhwala, HEC imagwiritsidwa ntchito ngati binder, disintegrant, and thickener mumapiritsi a mapiritsi. Chikhalidwe chake chosungunuka m'madzi chimapangitsa kuti chikhale choyenera pamitundu yosiyanasiyana yapakamwa.
   • Zopangira Zosamalira Munthu: Zopezeka mu zodzoladzola, ma shampoos, ndi mafuta odzola, HEC imapereka mamasukidwe akayendedwe ndi kukhazikika kwa mapangidwe mumakampani osamalira anthu.
   • Makampani a Mafuta ndi Gasi: HEC imagwiritsidwa ntchito pobowola madzi monga rheology modifier ndi wowongolera kutaya kwamadzi.
6. Viscosity Control:
   • Kulemera kwa molekyulu ya HEC kumathandizira kuti ikhale yogwira mtima pakuwongolera kukhuthala. Katunduyu ndi wamtengo wapatali pamagwiritsidwe pomwe makulidwe omwe mukufuna kapena mawonekedwe amtundu wa chinthu akuyenera kusamalidwa.
7. Kugwirizana:
   • HEC nthawi zambiri imagwirizana ndi zida zina zambiri komanso zowonjezera zomwe zimagwiritsidwa ntchito m'mafakitale osiyanasiyana. Komabe, kuyezetsa kufananira kuyenera kuchitidwa popanga ndi zigawo zinazake.
8. Miyezo Yabwino:
   • Opanga nthawi zambiri amapereka mafotokozedwe ndi miyezo yapamwamba ya zinthu za HEC, kuwonetsetsa kusasinthasintha ndi kudalirika pakugwira ntchito. Miyezo iyi ingaphatikizepo mfundo zokhudzana ndi kulemera kwa maselo, chiyero, ndi zina zofunika.

Ma cellulose a Hydroxyethyl okhala ndi mamolekyu olemera a 1000000 ndi polima wosunthika wokhala ndi ntchito zosiyanasiyana m'mafakitale, makamaka m'mapangidwe omwe kukhuthala kwakukulu ndi kusungunuka kwamadzi ndikofunikira. Ndikofunikira kutsatira malangizo ovomerezeka ndi mapangidwe operekedwa ndi opanga kuti apeze zotsatira zabwino pamapulogalamu apadera.
