EHEC na MEHEC

EHEC (ethyl hydroxyethyl cellulose) na MEHEC (methyl ethyl hydroxyethyl cellulose) bụ ụdị abụọ dị mkpa nke cellulose ethers nke a na-ejikarị eme ihe na ụlọ ọrụ dị iche iche, gụnyere ụlọ ọrụ agba na mkpuchi.Ka anyị lebakwuo anya na nke ọ bụla:

1. EHEC (Ethyl Hydroxyethyl Cellulose):
   • Ọdịdị kemịkal: EHEC sitere na cellulose site na iwebata ma ethyl na hydroxyethyl otu n'ime ọkpụkpụ azụ cellulose.
   • Ngwongwo na Ọrụ:
     • EHEC bụ soluble na mmiri na-emepụta uzo, viscous ngwọta.
     • Ọ na-arụ ọrụ dị ka ihe na-eme ka ọkpụkpụ na rheology modifier na agba na mkpuchi mmiri, na-achịkwa viscosity na imeziwanye ngwa ngwa.
     • EHEC na-enye pseudoplastic ma ọ bụ nke na-akpụ akpụ omume ka ọ na-esepụta ihe osise, nke pụtara viscosity na-ebelata site na ọnụ ọgụgụ shear na-abawanye, na-eme ka ngwa dị mfe na brushability dị nro.
   • Ngwa:
     • A na-eji EHEC eme ihe n'ọtụtụ ebe n'ime ime na n'èzí agba, primers, na mkpuchi iji nweta ihe a na-achọsi ike, ọsọ, na nhazi ọkwa.
     • Ọ dị irè karịsịa n'ụdị ebe a na-achọ viscosity dị elu na ọnụ ọgụgụ dị ala nke shea maka sag resistance na mma mmepụta ihe nkiri.
2. MEHEC (Methyl Ethyl Hydroxyethyl Cellulose):
   • Nhazi kemịkalụ: MEHEC bụ ether cellulose gbanwetụrụ nwere ihe methyl, ethyl na hydroxyethyl nọ n'ọkpụkpụ cellulose.
   • Ngwongwo na Ọrụ:
     • MEHEC na-egosiputa solubility na rheological Njirimara na EHEC mana enwere ọdịiche dị na arụmọrụ.
     • Ọ na-enye ike njigide mmiri dị mma ma e jiri ya tụnyere EHEC, na-eme ka ọ dị mma maka nhazi ebe a na-achọ oge imeghe ma ọ bụ ọganihu agba agba.
     • MEHEC na-enye nkwalite arụmọrụ na nkwụsi ike n'ọtụtụ pH na ọnọdụ okpomọkụ.
   • Ngwa:
     • MEHEC na-achọta ngwa na agba mmiri, mkpuchi, na ihe owuwu ebe a na-achọ ka njigide mmiri dị mma, nkwụsi ike, na njikwa rheological.
     • A na-ejikarị ya eme ihe maka eserese ịchọ mma, mkpuchi textured, na ihe ọpụrụiche na-agwụcha ebe ogologo oge ọrụ na ihe ndị na-asọpụta ka mma dị oke egwu.

Ma EHEC na MEHEC bụ cellulose ethers dị iche iche nke na-enye ndị na-emepụta mgbanwe mgbanwe iji nweta njirimara arụmọrụ achọrọ na agba na mkpuchi mmiri.Nkwekọrịta ha na ihe mgbakwunye ndị ọzọ, ịdị mfe nke ntinye n'ime usoro, na ike ịkwalite ihe ndị dị mkpa dị ka njikwa viscosity, njide mmiri, na ngwa ngwa na-eme ka ha bụrụ ihe bara uru n'ichepụta ihe mkpuchi ịchọ mma dị elu.
