Moetsi oa hydroxyethylcellulose ke mang?

Hydroxyethylcellulose (HEC) ke polymer ea maiketsetso e sebelisoang liindastering tse fapaneng bakeng sa merero e fapaneng. Ke polima e se nang ionic, e qhibilihang ka metsing e nkiloeng ho selulose, 'me e sebelisoa e le ntho e teteaneng, emulsifier, stabilizer, le moemeli ea emisang.

HEC e etsoa ke lik'hamphani tse fapa-fapaneng, ho akarelletsa le Dow Chemical, BASF, Ashland, AkzoNobel, le Clariant. Dow Chemical ke e 'ngoe ea lihlahisoa tse kholo ka ho fetisisa tsa HEC,' me e hlahisa mefuta e fapaneng ea limaraka tsa HEC, ho kenyeletsa le li-brand tsa Dowfax le Natrosol. BASF e hlahisa mofuta oa Cellosize oa HEC, ha Ashland e hlahisa mofuta oa Aqualon. AkzoNobel e hlahisa mefuta ea Aqualon le Aquasol ea HEC, 'me Clariant e hlahisa mofuta oa Mowiol.

E 'ngoe le e' ngoe ea lik'hamphani tsena e hlahisa limaraka tse fapaneng tsa HEC, tse fapaneng ho ea ka boima ba limolek'hule, viscosity le thepa e 'ngoe. Boima ba molek'hule ba HEC bo ka tloha ho 100,000 ho ea ho 1,000,000, 'me viscosity e ka tloha ho 1 ho ea ho 10,000 cps. Litekanyetso tsa HEC tse hlahisoang ke k'hamphani ka 'ngoe li boetse li fapana ho ea ka ho qhibiliha ha tsona, botsitso le ho lumellana le lisebelisoa tse ling.

Ho phaella ho bahlahisi ba ka sehloohong ba HEC, ho boetse ho na le lik'hamphani tse nyenyane tse ngata tse hlahisang HEC. Lik'hamphani tsena li kenyelletsa Lubrizol, leKima Chemical. E 'ngoe le e' ngoe ea lik'hamphani tsena e hlahisa mefuta e fapaneng ea limaraka tsa HEC, tse fapaneng ho ea ka thepa ea tsona.

Ka kakaretso, ho na le lik'hamphani tse fapaneng tse hlahisang HEC, 'me k'hamphani e' ngoe le e 'ngoe e hlahisa mefuta e sa tšoaneng ea lihlopha tsa HEC. Litekanyetso tsa HEC tse hlahisoang ke k'hamphani ka 'ngoe li fapana ho ea ka boima ba limolek'hule, viscosity, solubility, botsitso, le ho lumellana le lisebelisoa tse ling.
