Methylcellulose (MC) bụ ihe e nwetara site na cellulose site na ọgwụgwọ methylation ma nwee ihe pụrụ iche nke anụ ahụ na kemịkal. Dị ka a ọtụtụ-eji ọtọ mgbakwunye, ọ na-arụ a dị oké mkpa ọrụ dị iche iche ulo oru ubi, gụnyere ụlọ ihe, nri, ọgwụ, ntecha na coatings, wdg Ya magburu onwe ndim, mmiri njigide, bonding, film-akpụ, emulsifying na stabilizing ọrụ na-eme methylcellulose. ihe dị mkpa n'ịkwalite na ịkwalite mmepụta mmepụta ihe.
1. Mmetụta dị arọ
Njirimara nke methylcellulose na-eme ka ọ bụrụ ihe mgbakwunye dị mkpa na ụlọ ọrụ ihe owuwu na mkpuchi. N'ime ụlọ ọrụ ihe owuwu, karịsịa na ngwa ngwa simenti na ngwaahịa gypsum, methylcellulose nwere ike ịbawanye nkwụsi ike na viscosity nke usoro ahụ, si otú a na-eme ka ọrụ nke ihe ahụ dịkwuo mma. Maka mkpuchi na agba, mgbakwunye nke methylcellulose nwere ike igbochi mmiri ahụ nke ọma ka ọ ghara ịdị oke mmiri ma mee ka adhesion na ịdị n'otu nke mkpuchi ahụ dịkwuo mma.
Usoro nke ndim bụ tumadi site na nhazi usoro netwọk na ngwọta site na methylcellulose. Agbụ nke molekụla nke methylcellulose na-emekọrịta ihe site na njikọ hydrogen dị na mmiri iji mepụta ngwọta nwere ụfọdụ viscosity. Usoro netwọk a nwere ike ijide ma dozie ụmụ irighiri mmiri, si otú ahụ na-abawanye viscosity na nkwụsi ike nke usoro mmiri mmiri.
2. Njide mmiri
N'ime ihe owuwu dị ka ụrọ ciment na gypsum slurries, ihe njide mmiri nke methylcellulose dị oke egwu. Ihe owuwu ụlọ chọrọ oke mmiri kwesịrị ekwesị iji sonye na mmeghachi omume n'oge usoro ọgwụgwọ. Mfu mmiri na-akaghị aka ga-eduga n'ịgwọta ihe adịghị mma, mbelata ike, ma ọ bụ mgbawa n'elu. Methylcellulose na-emepụta ihe nkiri dị gịrịgịrị n'elu ihe ahụ iji gbochie oke evaporation nke mmiri ma hụ na ciment, plasta na ihe ndị ọzọ nwere mmiri zuru oke n'oge usoro ọgwụgwọ, si otú a na-eme ka ike na ịdịte aka ha dịkwuo mma.
Mmetụta a na-ejigide mmiri dị mkpa karịsịa na mpaghara akọrọ ma ọ bụ okpomọkụ dị elu, na-ekwe ka methylcellulose kwalite arụmọrụ nke mmepụta mmepụta ihe n'okpuru ọnọdụ gburugburu ebe obibi.
3. Njikọ na ịkwalite ike ihe onwunwe
Njirimara njikọta nke methylcellulose dịkwa mma na mmepụta ụlọ ọrụ. Dịka ọmụmaatụ, na tile adhesives na ụdị ndị ọzọ na-ejikọta ọnụ, methylcellulose nwere ike ime ka adhesion nke nhazi ahụ dịkwuo mma, na-ekwe ka ihe eji eme ihe na-arụ ọrụ nke ọma. Ọdịdị ogologo eriri molekụla nke methylcellulose nwere ike iji ihe matriks na-emekọ ihe iji kwalite ike njikọ, si otú a na-eme ka ike nhazi nke ihe ahụ dịkwuo elu.
N'ime plastik ndị na-eme ka eriri fiber (FRP), methylcellulose nwere ike ịkwalite ike na ike nke ihe ndị mejupụtara ya site na nhazi nke fibrous ya, na-enye ihe ahụ ike dị elu ma na-eyi nkwụsi ike, si otú a na-eme ka ọ dịkwuo ogologo oge na ngwa mmepụta ihe. mmekọahụ.
4. Nhazi ihe nkiri
Methylcellulose nwere ikike imepụta ihe nkiri dị mma na ngwọta, yana akụrụngwa a ejirila ya n'ọtụtụ mpaghara mmepụta ihe. Na mkpuchi mkpuchi na ụlọ ọrụ agba, methylcellulose nwere ike ịmepụta ihe nkiri nchebe otu nke na-eme ka mmiri na-eguzogide mmiri na nguzogide kemịkalụ nke mkpuchi.
N'ụlọ ọrụ nri, a na-ejikarị methylcellulose eme ihe na mkpuchi ma ọ bụ usoro ịse ihe nkiri, ọkachasị na mkpọ mkpụrụ osisi, akwụkwọ nri na nri ndị ọzọ. Site n'ịmepụta ihe nkiri dị mkpa, methylcellulose na-egbu oge nkwụsị mmiri ma na-echebe nri site na gburugburu ebe obibi.
5. Nkwụsi ike na emulsification
Methylcellulose nwere ike ịmepụta ihe ngwọta dị elu mgbe ọ gbazere na mmiri, nke nwere mmetụta na-eme ka ahụ sie ike na emulsifying. Ihe onwunwe a dị mkpa karịsịa na ụlọ ọrụ dị ka mkpuchi, agba, ihe ịchọ mma na nkwadebe ọgwụ. Na agba na agba, methylcellulose nwere ike ime ka mgbasa nke pigmenti guzosie ike, gbochie nhazi, ma melite gloss na ịdị n'otu nke mkpuchi; N'ime usoro ịchọ mma, methylcellulose na-eje ozi dị ka emulsifier iji mee ka mmiri-mmanụ agwakọta usoro ma gbochie Stratification.
N'ime nkwadebe ọgwụ, a na-ejikarị methylcellulose eme ka ọ sie ike na ịkwado nkwadebe mmiri ọnụ yana dịka onye na-ebu ọgwụ. Viscosity ya na ihe ndị na-emepụta ihe nkiri nwere ike inyere aka wepụ ọgwụ ahụ nwayọọ nwayọọ, gbasaa oge mmetụta ọgwụ, ma melite bioavailability nke ọgwụ ahụ.
6. Thermal gelling Njirimara
Otu ihe dị mkpa anụ ahụ nke methylcellulose bụ omume gelling ya pụrụ iche, nke ọ na-aghọ gel mgbe ọ na-ekpo ọkụ. Njirimara a na-eme ka ọ bụrụ nke a na-apụghị dochie anya na ụfọdụ usoro mmepụta ihe pụrụ iche. Dịka ọmụmaatụ, n'ụlọ ọrụ nri, a na-eji methylcellulose na-edozi nri ndị nwere obere abụba. Gel a na-emepụta mgbe kpochara ọkụ nwere uto yiri abụba, na-ekwe ka ihe oriri ndị dị obere na-eme ka ọ dị mma na ọdịdị dị mma. N'ime ụlọ ọrụ ihe owuwu, ihe onwunwe gelling a na-ekpo ọkụ na-eme ka ịdịte aka na nkwụsi ike nke ihe owuwu na gburugburu ebe okpomọkụ dị elu.
7. Biocompatibility na gburugburu ebe obibi enyi
Methylcellulose, dị ka ihe sitere n'okike, nwere ezigbo ihe ndakọrịta na gburugburu ebe obibi. Nke a na-eme ka ọ na-ewu ewu na usoro mmepụta ihe nke oge a, karịsịa na mpaghara nwere ihe nchebe gburugburu ebe obibi dị elu dị ka ụlọ akwụkwọ ndụ akwụkwọ ndụ, mkpuchi gburugburu ebe obibi na ihe nkwakọ ngwaahịa na-emebi emebi. Methylcellulose nwere ike iweda ya n'ụzọ nkịtị, na-ebelata ibu gburugburu ebe obibi ma na-agbaso usoro mmepụta ihe nke mmepe na-adigide.
8. Mma nhazi arụmọrụ
Na mmepụta mmepụta ihe, methylcellulose nwere ike melite nhazi nhazi. Dịka ọmụmaatụ, na ihe owuwu ụlọ, methylcellulose nwere ike ime ka mmiri dị na mmiri na-ejigide ihe, si otú a na-eme ka ịdị mma na ịrụ ọrụ nke ọma dịkwuo mma; na ihe ịchọ mma na nkwadebe ọgwụ, methylcellulose nwere ike melite nkwụsi ike nke usoro ma belata mmiri ozuzo. na delamination, si otú ịgbatị ndụ shelf nke ngwaahịa. Njirimara ndị a na-enye methylcellulose aka imeziwanye nrụpụta mmepụta ihe mgbe ọ na-ebuli usoro mmepụta ihe.
Dị ka ihe mgbakwunye multifunctional, a na-eji methylcellulose mee ihe n'ọtụtụ ụlọ ọrụ dị ka ihe owuwu, nri, ọgwụ, ihe ịchọ mma, mkpuchi, wdg n'ihi ọtụtụ ihe ndị dị ka ịgbara mmiri, njigide mmiri, njikọ, ịmepụta ihe nkiri, nkwụsịtụ, emulsification na gelling thermal. na-arụ ọrụ dị mkpa n'ọhịa. Ọ nwere ike ọ bụghị naanị welie ihe anụ ahụ nke mmepụta mmepụta ihe, kamakwa melite mmepụta mmepụta ihe na izute mkpa ụlọ ọrụ dị iche iche. N'otu oge ahụ, biocompatibility na enyi na gburugburu ebe obibi nke methylcellulose na-emekwa ka ọ bụrụ ihe dị mma nke na-emezu ihe achọrọ maka mmepe na-adịgide adịgide. Site n'iji ezi uche na-etinye methylcellulose na usoro mmepụta ihe, ọ bụghị nanị na ọ na-eme ka mma ngwaahịa dịkwuo mma, kamakwa ịkwalite ọganihu na mmepe nke nkà na ụzụ mmepụta ihe.
