Polyanionic cellulose bụ polymer

Polyanionic cellulose (PAC) bụ n'ezie polymer, kpọmkwem ihe mmepụta nke cellulose. Ngwakọta a na-adọrọ mmasị na-achọta ngwa ngwa n'ofe ụlọ ọrụ dị iche iche n'ihi njirimara pụrụ iche na arụmọrụ ya.

Ọdịdị nke Polyanionic Cellulose:

Polyanionic cellulose na-enweta site na cellulose, nke bụ otu n'ime ihe ndị kasị eke polymers na Ụwa. Cellulose bụ polysaccharide linear nke mejupụtara nkeji glucose ugboro ugboro jikọtara ya na β(1→4) glycosidic bonds. Ọ na-etolite akụkụ ntọala bụ isi nke mgbidi cell osisi. A na-agbanwe cellulose polyanionic cellulose, ebe a na-eji otu anionic dochie ụfọdụ otu hydroxyl nke agbụ cellulose. Otu anionic ndị a na-agụnyekarị carboxylate (-COO⁻), sulfonate (-SO₃⁻), ma ọ bụ phosphate (-PO₄⁻) otu. Iwebata ndị otu anionic ndị a na-enye mmiri solubility na ihe ndị ọzọ na-achọsi ike na polymer.

Nchịkọta nke cellulose polyanionic:

A na-emepụtakarị cellulose polyanionic site na mgbanwe kemịkalụ nke cellulose. Otu usoro a na-ahụkarị gụnyere imeghachi cellulose na ihe anhydride n'okpuru ọnọdụ ụfọdụ iji webata otu anionic na ọkpụkpụ azụ cellulose. Ọnọdụ mmeghachi omume na ụdị anhydride ejiri mee ihe na-ekpebi ogo ngbanwe (DS) nke otu anionic na agbụ cellulose. Ụkpụrụ DS dị elu na-ebute oke mmiri solubility na arụ ọrụ dị mma na ụfọdụ ngwa.

Njirimara nke cellulose polyanionic:

Polyanionic cellulose na-egosipụta ọtụtụ ihe pụrụ iche nke na-eme ka ọ dabara maka ọtụtụ ngwa:

Mmiri Solubility: Iwebata ndị otu anionic na-enye mmiri solubility na polyanionic cellulose, na-enye ya ohere ịmepụta ngwọta kwụsiri ike ma ọ bụ gbasaa na mmiri. Ihe onwunwe a bara uru karịsịa na ngwa ebe a na-ahọrọ usoro mmiri.

Mgbanwe nke ukwuu na Rheology: A na-eji polyanionic cellulose eme ihe dị ka onye na-eme ihe na-akụda mmụọ na ihe ngbanwe rheology na ụlọ ọrụ dị iche iche, gụnyere nri, ọgwụ na ngwaahịa nlekọta onwe onye. Ọ na-enye viscosity ma melite nkwụsi ike na udidi nke usoro.

Ntugharị na njikwa mfu mmiri: N'ụlọ ọrụ ndị dị ka mkpọ mmanụ, a na-eji polyanionic cellulose eme ihe maka ike ọ na-ebugharị ihe siri ike kwụsịtụrụ na ịchịkwa mfu mmiri. Ọ na-enyere aka ịnọgide na-enwe nkwụsi ike nke olulu mmiri ma na-akwalite ịrụ ọrụ nke mkpọpu ihe.

Ndakọrịta: Polyanionic cellulose dakọtara na ọtụtụ kemịkalụ ndị ọzọ na ihe mgbakwunye, na-eme ka ọ bụrụ ihe dị iche iche maka imepụta na ngwa dị iche iche. Enwere ike itinye ya n'ụzọ dị mfe n'ime usoro dị iche iche na-enweghị ịkpata nsogbu ndakọrịta.

Biodegradability: N'agbanyeghị mgbanwe nke sịntetik ya, polyanionic cellulose na-ejigide biodegradability nke cellulose. Njirimara a dị mkpa maka ibelata mmetụta gburugburu ebe obibi, karịsịa na ngwa ebe mkpofu bụ nchegbu.

Ngwa nke Polyanionic Cellulose:

Polyanionic cellulose na-achọta ngwa dị iche iche n'ọtụtụ ụlọ ọrụ:

Industrylọ ọrụ mmanụ na gas: Na mpaghara mmanụ na gas, a na-ejikarị PAC dị ka ihe mgbakwunye viscosifier na njikwa mfu mmiri na-egwu mmiri. Ọ na-enyere aka ịnọgide na-enwe nkwụsi ike nke olulu mmiri, na-eme ka ihicha oghere dị elu, ma na-eme ka ọ dị mma igwu mmiri.

Ụlọ ọrụ nri: N'ime ụlọ ọrụ nri, PAC na-eje ozi dị ka onye na-eme ka ọ sie ike, stabilizer, na texturizer na ngwaahịa dị iche iche dị ka sauces, uwe, ngwaahịa mmiri ara ehi, na desserts. Ọ na-eme ka mmetụta ọnụ dịkwuo mma, na-eme ka nkwụsi ike, na-egbochi syneresis na nhazi nri.

Ọgwụ: A na-eji polyanionic cellulose eme ihe n'ụdị ọgwụ dị ka ihe na-ekekọta, na-ekesa, na ihe ntọhapụ a na-achịkwa na mbadamba na capsules. Ọ na-enyere aka n'ịkọkọta mbadamba nkume, na-eme ka mwepụta ọgwụ otu otu, ma na-akwalite nnabata ndị ọrịa.

Ngwaahịa nlekọta onwe onye: N'ime ngwaahịa nlekọta onwe onye, ​​PAC na-arụ ọrụ dị ka onye na-ebu ibu, onye nkwusioru, na emulsion stabilizer na ngwaahịa dị ka shampoos, lotions, na creams. Ọ na-eme ka viscosity ngwaahịa dịkwuo mma, na-eme ka udidi dị mma, ma gbochie nkewa nke oge.

Ihe eji ewu ewu: A na-eji PAC na ụlọ ọrụ ihe owuwu dị ka onye na-ejigide mmiri, ihe na-agbapụta, na rheology modifier n'ụdị nke sitere na ciment dị ka ngwa agha, grouts, na plasta. Ọ na-eme ka arụ ọrụ dịkwuo mma, na-ebelata mmiri na-efunahụ, ma na-eme ka adhesion na ihe ndị na-emepụta ihe.

Mmetụta gburugburu ebe obibi na nkwado:

Ọ bụ ezie na cellulose polyanionic na-enye uru dị iche iche n'ihe gbasara ịrụ ọrụ na ịrụ ọrụ, a ga-atụlekwa mmetụta gburugburu ebe obibi ya. Dị ka ihe mmepụta nke cellulose, PAC na-ejigide biodegradability nke polymer nne na nna ya. Nke a pụtara na n'okpuru ọnọdụ kwesịrị ekwesị, microorganisms nwere ike imebi polyanionic cellulose n'ime ihe ndị na-adịghị emerụ ahụ, na-enye aka na nkwado gburugburu ebe obibi.

Ọzọkwa, ọdịdị cellulose na-emegharị ọhụrụ dị ka akụrụngwa maka njikọ PAC na-enye uru n'ihe gbasara nnweta akụrụngwa yana mbelata ịdabere na mmanụ ọkụ. Mgbalị na-aga n'ihu iji kwalite usoro njikọ ahụ na ịkwalite biodegradability nke ihe ndị na-emepụta polyanionic cellulose iji belata akara ukwu gburugburu ebe obibi ha.

polyanionic cellulose bụ polymer vasatail ewepụtara site na cellulose, na-enye ọtụtụ ngwa ngwa n'ofe ụlọ ọrụ dị iche iche. Ngwongwo ya pụrụ iche, gụnyere mmiri solubility, ike ịgbakọ, ndakọrịta, na biodegradability, na-eme ka ọ bụrụ ihe bara uru n'ọtụtụ nhazi. Ka ọ na-enye uru arụmọrụ dị ịrịba ama, mbọ na-aga n'ihu iji hụ na a na-emepụta polyanionic cellulose na ihe ndị sitere na ya n'ụzọ kwesịrị ekwesị na gburugburu ebe obibi, si otú ahụ na-edozi mkpa ụlọ ọrụ na ihe mgbaru ọsọ nkwado.
