Lekwasị anya na cellulose ethers

Kedu uru nke cellulose ethers dị ka ihe na-ejikọta na mkpuchi?

A na-ejikarị cellulose ethers, dị ka methyl cellulose (MC), hydroxypropyl methylcellulose (HPMC), na ethyl cellulose (EC), dị ka ihe eji eme ihe na mkpuchi n'ihi ihe ha pụrụ iche na ọtụtụ uru. Nke a bụ nkọwa zuru oke na-ekpuchi akụkụ dị iche iche:

Nhazi ihe nkiri: Cellulose ethers na-enye aka n'ịmepụta ihe nkiri na-aga n'ihu, otu ihe mgbe a na-eji ya dị ka ihe eji eme ihe na mkpuchi. Ihe nkiri a na-enye ihe mgbochi na-echebe mkpụrụ osisi site na gburugburu ebe obibi dịka mmiri mmiri, kemịkalụ, na radieshon UV.

Adhesion: Ihe ndị a na-ejikọta ọnụ na-eme ka adhesion dị n'etiti mkpuchi na mkpụrụ, na-akwalite ịdịte aka na ogologo ndụ nke usoro mkpuchi. Nrachi dị mma na-eduga n'ibelata ohere nke ọnya, ịhịa aka n'ahụ, ma ọ bụ bee ka oge na-aga.

Ọkpụkpụ na nchịkwa Rheology: Cellulose ethers na-egosipụta ihe ndị na-eme ka ọ dị mma, na-enye ohere ịchịkwa viscosity na rheology nke usoro mkpuchi. Nke a na-enyere aka igbochi ịsa mmiri ma ọ bụ ntapu n'oge ngwa, na-ahụ na ọbụna mkpuchi na otu.

Njide mmiri: Otu n'ime uru dị mkpa nke cellulose ethers bụ ikike ha nwere idowe mmiri n'ime nhazi mkpuchi. Nke a na-agbatị oge ihicha, na-eme ka nhazi ọkwa kwesịrị ekwesị na ibelata ihe ize ndụ nke ntụpọ dị n'elu dị ka cratering ma ọ bụ mmetụta bee oroma.

Ịrụ ọrụ emelitere: Mkpuchi nwere cellulose ethers dị mfe ijikwa ma tinye ya n'ọrụ, ekele maka ịrụ ọrụ ha ka mma yana mbelata ọchịchọ ịgbasa ma ọ bụ ịgbasa n'oge ngwa. Nke a na-eme ka arụmọrụ zuru oke nke usoro mkpuchi ahụ dịkwuo elu.

Enwekwukwa Nkwụsi ike: Cellulose ethers na-enye aka na nkwụsi ike nke usoro mkpuchi site na igbochi nkewa nkewa, sedimentation, ma ọ bụ flocculation nke pigmenti na ihe mgbakwunye ndị ọzọ. Nke a na-eme ka arụmọrụ na-agbanwe agbanwe na ọdịdị nke mkpuchi na-aga n'ihu n'oge.

Ndakọrịta na ihe mgbakwunye ndị ọzọ: Ihe ndị a na-ejikọta ya na ọtụtụ ihe mgbakwunye na-ejikarị eme ihe na mkpuchi, dị ka pigmenti, fillers, dispersants, and defoamers. Nke a na-agbanwe agbanwe na-enye ohere ịmepụta ihe mkpuchi na ihe eji eme ihe iji mezuo ihe ngwa ngwa chọrọ.

Enyi na gburugburu ebe obibi: Cellulose ethers na-enweta site na ihe ndị nwere ike imeghari, nke bụ isi cellulose enwetara site na eriri osisi. N'ihi nke a, a na-ewere ha dị ka ndị ọzọ na-emetụta gburugburu ebe obibi maka ihe nkedo sịntetik nke sitere na petrochemicals.

Nrube isi nke usoro iwu: Ọtụtụ cellulose ethers eji na mkpuchi na-agbaso ụkpụrụ iwu maka nchekwa na nchekwa gburugburu ebe obibi, dị ka ihe mgbochi na ihe ọkụkụ na-agbanwe agbanwe (VOC) na ihe ndị dị ize ndụ. Nke a na-eme ka mkpuchi kpuchie ya na ihe ndị a na-ejikọta ya na-emezu ihe ndị a chọrọ n'iwu na ahịa dị iche iche.

Ngwa ngwa obosara: Cellulose ethers na-achọta ngwa n'ụdị dị iche iche nke usoro mkpuchi, gụnyere eserese ụlọ, ihe mkpuchi ụlọ ọrụ, mkpuchi osisi, na mkpuchi pụrụ iche dị ka akwụkwọ ink na nrapado. Ntughari ha na-eme ka ha bụrụ ihe ndị dị mkpa na ụlọ ọrụ mkpuchi.

Cellulose ethers na-enye ọtụtụ uru dị ka ihe na-ejikọta na mkpuchi, sitere na nhazi ihe nkiri na-eme ka ọ dịkwuo mma na nkwụsi ike na nkwụsi ike na ịdị mma gburugburu ebe obibi. Ntughari ha na ndakọrịta na ihe mgbakwunye ndị ọzọ na-eme ka ha bụrụ ihe dị mkpa na nhazi nke mkpuchi mkpuchi dị elu maka ngwa dị iche iche.
