Ngwa ngwa ma ọ bụ na-abụghị ngwa ngwa cellulose HPMC maka mkpuchi

A na-eji cellulose HPMC, ma ọ bụ hydroxypropyl methylcellulose, mee ihe na ụlọ ọrụ mkpuchi. Ọ bụ ihe na-adịghị egbu egbu, dị oke arụ ọrụ na ihe dị iche iche. A na-enweta HPMC site na eriri osisi ma na-agbaze ngwa ngwa na mmiri. Ọ nwere ngwa ngwa dị iche iche na ihe owuwu ụlọ, ihe mkpuchi mkpuchi, adhesives na ụlọ ọrụ ndị ọzọ metụtara ya.

Cellulose HPMC na-abịa n'ụdị abụọ: ngwa ngwa na nke na-abụghị ozugbo. Onye ọ bụla nwere ihe pụrụ iche nke ya ma dabara maka ngwa ngwa. N'isiokwu a, anyị ga-enyocha ọdịiche dị n'etiti HPMC cellulose ozugbo na HPMC cellulose na-abụghị ngwa ngwa maka mkpuchi.

Ngwa ngwa cellulose HPMC

Ngwa ngwa Cellulose HPMC bụ ụdị HPMC nke na-agbaze na mmiri oyi. Ọ nwere oge mgbasa ngwa ngwa, nke pụtara na enwere ike ịgbasa ya na mmiri n'ime sekọnd. A na-ejikarị HPMC ngwa ngwa na mkpuchi na-achọ ịgbara ngwa ngwa, dị ka nkwusioru, emulsions na ngwa viscosity dị elu.

Otu n'ime isi uru nke ozugbo cellulose HPMC bụ ya magburu onwe dispersibility. Ọ na-agbaze n'ime mmiri na-enweghị ọkpụkpụ ma ọ bụ lumps ọ bụla. Njirimara a na-eme ka ọ dị mma maka iji ya mee ihe n'ụdị ihe siri ike dị elu ka ọ na-eme ka viscosity na-agbanwe agbanwe n'oge dum.

Ngwa ngwa cellulose HPMC bụkwa nke ọma ịrụ ọrụ nke ọma, na-enye ndị magburu onwe ndim Njirimara na ala ịta. Ọ naghị emetụta agba ma ọ bụ gloss nke agba, na-eme ka ọ dị mma maka ọtụtụ nhazi. Na mgbakwunye, HPMC ozugbo na-eguzogide enzymes, acids, na alkalis, nke pụtara na ọ nwere ezigbo nkwụsi ike nke kemịkal.

HPMC cellulose na-adịghị ozugbo

N'aka nke ọzọ, HPMC cellulose na-abụghị ozugbo adịghị soluble na mmiri oyi ma na-achọ ikpo ọkụ iji gbazee. Ọ na-ewe ogologo oge iji gbazee karịa HPMC cellulose ozugbo ma na-achọ okpomọkụ dị elu ka ọ gbasaa kpamkpam. A na-ejikarị HPMC ndị na-abụghị ngwa ngwa eme ihe na mkpuchi ebe a na-achọsi ike ngwa ngwa na nke nta nke nta.

Otu n'ime uru ndị bụ isi nke cellulose HPMC na-abụghị ngwa ngwa bụ ikike ya inye mmetụta nke ntanye nwayọọ nwayọọ karịa oge. Ọ naghị ebute mgbanwe mberede na viscosity nke nwere ike imetụta àgwà niile nke agba. HPMC na-abụghị ngwa ngwa nwere ezigbo rheological Njirimara na ọ dị mma maka iji na mkpuchi ebe a chọrọ njikwa dị elu na ntinye na nhazi nke ngwaahịa ahụ.

HPMC cellulose na-abụghị ngwa ngwa nwekwara ihe ndị na-emepụta ihe nkiri dị mma, nke pụtara na ọ na-enyere aka melite ịdịte aka nke mkpuchi. Ọ nwere ike iguzogide ihu igwe, UV radieshon na ihe ndị ọzọ gburugburu ebe obibi, na-eme ka mkpuchi na-adịgide adịgide n'oge. Tụkwasị na nke ahụ, HPMC na-abụghị ngwa ngwa nwere ezigbo mmachi elu, nke na-egbochi mkpuchi site na bee ma ọ bụ chipping.

Ma ozugbo na nke na-abụghị ngwa ngwa cellulose HPMC nwere pụrụ iche Njirimara na uru na-eme ka ha dabara maka kpọmkwem ngwa na coatings ụlọ ọrụ. Ngwa ngwa cellulosic HPMC dị mma maka mkpuchi na-achọ ịgbara ngwa ngwa, ebe HPMC na-abụghị ngwa ngwa kacha mma maka ngwa chọrọ ngwa ngwa na nke nta nke nta.

N'agbanyeghị ụdị cellulose HPMC eji, uru nke ihe a vasatail bụ ihe a na-apụghị ịgbagha agbagha. Ọ na-agbakwụnye uru na mkpuchi site n'ịkwalite ịdị arọ, nhazi, adhesion na ogologo oge. Na mgbakwunye, ọ naghị egbu egbu na gburugburu ebe obibi, na-eme ka ọ bụrụ nhọrọ magburu onwe ya maka usoro iji belata mmetụta gburugburu ebe obibi ha.

Cellulose HPMC bụ ihe na-arụ ọrụ nke ọma na nke nwere ike iweta uru dị ukwuu na mkpuchi. Ojiji ya dị oke mkpa iji meziwanye àgwà nke agba, nke na-emesị emetụta afọ ojuju zuru ezu nke onye ọrụ njedebe.
