Hydroxypropyl methylcellulose HPMC Njirimara

Ethers cellulose a na-ejikarị gụnyere HEC, HPMC, CMC, PAC, MHEC na ihe ndị yiri ya. Ether cellulose na-abụghị nke ionic nke mmiri na-edozi mmiri nwere nrapado, nkwụsi ike nkesa na ikike ijide mmiri, ọ bụkwa ihe mgbakwunye a na-ejikarị eme ihe maka ihe owuwu ụlọ. A na-eji HPMC, MC ma ọ bụ EHEC eme ihe n'ọtụtụ ciment ma ọ bụ gypsum dabeere na ya, dị ka ngwa ngwa masonry, ngwa ngwa ciment, mkpuchi ciment, gypsum, ngwakọta cimentious, na milky putty, wdg, nke nwere ike ịkwalite mgbasa nke ciment ma ọ bụ ájá ájá. ma na-emeziwanye Adhesion, nke dị ezigbo mkpa maka plasta, tile ciment na putty. A na-eji HEC mee ihe na ciment, ọ bụghị naanị dị ka onye na-azụ azụ, kamakwa dịka onye na-ejigide mmiri. HEHPC nwekwara ngwa a.

Ngwaahịa HPMC Hydroxypropyl methylcellulose na-ejikọta ọtụtụ ihe anụ ahụ na kemịkal n'ime ngwaahịa pụrụ iche nwere ọtụtụ ojiji na akụrụngwa:

Njide mmiri: Ọ nwere ike idowe mmiri n'elu ebe ndị nwere oghere dị ka mbadamba ciment na brik.

Ịme ihe nkiri: Ọ nwere ike ịmepụta ihe nkiri na-enweghị atụ, siri ike ma dị nro nke nwere oke mmanu mmanu.

Ngwakọta solubility: Ngwaahịa a na-agbaze na ụfọdụ ihe mgbaze organic, dị ka nha kwesịrị ekwesị nke ethanol/mmiri, propanol/water, dichloroethane na usoro ihe mgbaze nke mejupụtara abụọ ihe mgbaze organic.

Gelation thermal: Mgbe mmiri na-ekpo ọkụ nke ngwaahịa na-ekpo ọkụ, gel ga-etolite, gel a kpụrụ ga-atụgharị ghọọ ngwọta mgbe ọ dị jụụ.

Ọrụ dị n'elu: Na-enye ọrụ elu na ngwọta iji nweta emulsification achọrọ na colloid nchebe, yana nkwụsị nke oge.

Nkwusioru: Hydroxypropyl methylcellulose na-egbochi ụmụ irighiri ihe siri ike idozi, si otú a na-egbochi nhazi nke sediments.

Colloid Nchekwa: Gbochie ụmụ irighiri mmiri na ụmụ irighiri ihe ka ha ghara ịchịkọta ma ọ bụ ịgbakọta.

Mmiri Soluble : Enwere ike ịgbaze ngwaahịa ahụ n'ime mmiri dị iche iche, ihe kachasị elu na-ejedebe naanị site na viscosity.

Inertness na-abụghị ionic: Ngwaahịa a bụ cellulose ether na-abụghị ionic nke na-ejikọtaghị ya na nnu ígwè ma ọ bụ ion ndị ọzọ na-emepụta ihe na-adịghị edozi.

Acid-base kwụsie ike: kwesịrị ekwesị maka ojiji na nso nke PH3.0-11.0.
