Kedu ihe Hydroxyethyl Cellulose na-eji?

 

Hydroxyethyl cellulose(HEC) bụ ihe na-abụghị ionic cellulose ether nke sitere na polymer material cellulose sitere na usoro etherification. Ọ bụ ihe na-esi ísì ụtọ, enweghị ụtọ, ntụ ntụ ọcha na-adịghị egbu egbu ma ọ bụ granule, nke nwere ike igbari na mmiri oyi iji mepụta ngwọta viscous na-egbuke egbuke, na nkwụsịtụ adịghị emetụta uru pH. Ọ nwere ndim, njide, na-agbasasị, emulsifying, imepụta ihe nkiri, nkwusioru, mgbasa ozi, ọrụ elu, ihe na-ejide mmiri na ihe na-egbochi nnu. Ejiri ya nke ọma na agba, ihe owuwu, akwa, kemịkalụ kwa ụbọchị, akwụkwọ, mkpọ mmanụ na ụlọ ọrụ ndị ọzọ.

 

Mpaghara ngwa ngwa:

1.Agba:Agba nke dabere na mmiri bụ mmiri viscous emebere ya na ihe mgbaze organic ma ọ bụ mmiri dabere na resin, ma ọ bụ mmanụ, ma ọ bụ emulsion, yana mgbakwunye na mgbakwunye kwekọrọ. Ihe mkpuchi nke mmiri na-arụ ọrụ nke ọma kwesịkwara inwe ọrụ arụmọrụ dị mma, ike nzuzo dị mma, mkpuchi mkpuchi siri ike, na njigide mmiri dị mma; cellulose ether bụ akụrụngwa kachasị mma iji nye ihe ndị a.

2.Cntụziaka:N'ime ụlọ ọrụ mmepụta ihe, a na-eji HEC mee ihe dị ka ihe mgbakwunye maka ihe ndị dị ka ihe mgbidi, ihe (gụnyere asphalt), taịl nile na ihe ndị na-emepụta ihe, nke nwere ike ime ka viscosity dịkwuo elu na ịgbanye ihe owuwu ụlọ, meziwanye adhesion, lubricity, na mmiri. njide.
