Kodi wopanga hydroxyethylcellulose ndi ndani?

Hydroxyethylcellulose (HEC) ndi polima opangidwa omwe amagwiritsidwa ntchito m'mafakitale osiyanasiyana pazifukwa zosiyanasiyana. Ndi polima yopanda ionic, yosungunuka m'madzi yomwe imachokera ku cellulose, ndipo imagwiritsidwa ntchito ngati thickening agent, emulsifier, stabilizer, ndi suspending agent.

HEC imapangidwa ndi makampani osiyanasiyana, kuphatikizapo Dow Chemical, BASF, Ashland, AkzoNobel, ndi Clariant. Dow Chemical ndi amodzi mwa opanga zazikulu kwambiri za HEC, ndipo amapanga magiredi osiyanasiyana a HEC, kuphatikiza mitundu ya Dowfax ndi Natrosol. BASF imapanga mtundu wa Cellosize wa HEC, pomwe Ashland imapanga mtundu wa Aqualon. AkzoNobel imapanga mtundu wa Aqualon ndi Aquasol wa HEC, ndipo Clariant amapanga mtundu wa Mowiol.

Iliyonse mwamakampaniwa imapanga masukulu osiyanasiyana a HEC, omwe amasiyana malinga ndi kulemera kwa maselo, kukhuthala, ndi zina. Kulemera kwa molekyulu ya HEC kumatha kuchoka ku 100,000 mpaka 1,000,000, ndipo kukhuthala kumatha kuchoka ku 1 mpaka 10,000 cps. Magulu a HEC opangidwa ndi kampani iliyonse amasiyananso malinga ndi kusungunuka kwawo, kukhazikika, komanso kugwirizana ndi zosakaniza zina.

Kuphatikiza pa opanga akuluakulu a HEC, palinso makampani ang'onoang'ono omwe amapanga HEC. Makampaniwa akuphatikizapo Lubrizol, ndiKima Chemical. Iliyonse mwamakampaniwa imapanga masukulu osiyanasiyana a HEC, omwe amasiyana malinga ndi katundu wawo.

Zonsezi, pali makampani osiyanasiyana omwe amapanga HEC, ndipo kampani iliyonse imapanga mitundu yosiyanasiyana ya HEC. Makalasi a HEC opangidwa ndi kampani iliyonse amasiyana malinga ndi kulemera kwawo kwa maselo, kukhuthala, kusungunuka, kukhazikika, komanso kuyanjana ndi zosakaniza zina.
