1. Ihe ndị bụ isi nke methylcellulose
Methylcellulose bụ enweghị agba, enweghị ụtọ, ntụ ntụ ma ọ bụ granule na-enweghị isi nwere mmịnye mmiri siri ike yana ezigbo solubility. A na-ewebata otu methoxy (-OCH₃) n'ime usoro ihe omimi ya. Mgbanwe a na-enye ya ụfọdụ akụrụngwa nke cellulose eke enweghị, gụnyere:
Solubility: Methylcellulose na-agbaze ngwa ngwa na mmiri oyi iji mepụta ngwọta colloidal transperent, ma ọ bụ ihe na-adịghị edozi na mmiri ọkụ, na-egosi njirimara nke thermogel. Ngwongwo thermogel a na-enyere ya aka inwe mmetụta na-ekpo ọkụ na ụfọdụ okpomọkụ ma nọgide na-enwe ezigbo nkwụsi ike morphological na okpomọkụ dị elu.
Biocompatibility: Ebe ọ bụ na methylcellulose sitere na cellulose eke, ọ naghị egbu egbu, ọ naghị agbakasị ahụ, ma dịkwa mfe biodegradable, n'ihi ya, ọ bụ enyi na gburugburu ebe obibi.
Ọkpụkpụ na nkwụsi ike: Methylcellulose nwere ike ịbawanye viscosity nke ngwọta n'ụzọ dị irè ma na-arụ ọrụ na-emekọ ihe. Ọ na-enwekwa nkwụsi ike dị mma, nke nwere ike inyere aka na-ekesa ihe ndị ọzọ dị na usoro ahụ ma gbochie ha idozi ma ọ bụ kewaa.
2. Ngwa nke methylcellulose na ụlọ ọrụ ihe owuwu
N'ụlọ ọrụ ihe owuwu, a na-ejikarị methylcellulose eme ihe na ihe ndị dị ka ngwa ngwa ciment, ntụ ntụ na ngwaahịa gypsum. Isi ọrụ ya gụnyere:
Thickener: Na ngwa ngwa ciment, methylcellulose na-abawanye viscosity, na-eme ka arụ ọrụ na ịrụ ọrụ nke ngwa agha dịkwuo mfe, na-eme ka ọ dị mfe ịrụ ọrụ, ma nwee ike igbochi nkwụsị mmiri na stratification nke ọma. Ọ na-eme ka ngwa agha ahụ dịkwuo mmiri ma na-arụ ọrụ nke ọma.
Onye na-ejigide mmiri: Methylcellulose nwere ezigbo njide mmiri, nke nwere ike belata mfu mmiri na ngwa ngwa ma gbatịa oge hydration nke ciment, si otú a na-emeziwanye mmetụta na ike. N'ọnọdụ ihu igwe kpọrọ nkụ, methylcellulose nwere ike ibelata evaporation mmiri ma gbochie mgbawa ngwa agha.
Mgbochi sagging: Ọ nwere ike ịkwalite ikike mgbochi nke ngwa agha, ọkachasị n'ihe owuwu kwụ ọtọ, iji zere mfu ihe ma hụ na ọkpụrụkpụ mkpuchi na-agbanwe agbanwe.
3. Ngwa nke methylcellulose na mkpuchi na adhesives
A na-eji Methylcellulose eme ihe n'ọtụtụ ebe na mkpuchi na adhesives dị ka onye na-agba ume na stabilizer, nke nwere ike ime ka arụmọrụ nke ngwaahịa ndị a dịkwuo mma.
Ịgba ụda na ụkpụrụ rheological: N'ime ihe mkpuchi mkpuchi, methylcellulose na-eme ka mmiri na-agbasa ya dịkwuo mma site n'ịbawanye viscosity nke mkpuchi. Ihe mkpuchi nke mkpuchi nwere ike ọ bụghị naanị igbochi sagging na eruba, kamakwa mee ka mkpuchi ahụ bụrụ otu ma na-agbanwe agbanwe, na-eme ka mmetụta ụlọ ahụ dịkwuo mma. N'oge usoro ihicha nke mkpuchi ahụ, ọ na-ekerekwa òkè n'ịgbochi mmiri ozuzo nke ihe ndị na-emepụta ihe na mgbawa nke mkpuchi.
Ihe na-emepụta ihe nkiri: Methylcellulose nwere ike inye ihe mkpuchi ahụ nke ọma na-emepụta ihe nkiri, na-eme ka mkpuchi ahụ sie ike ma na-eyi ya, na inwe ụfọdụ nkwụsị mmiri na ihu igwe. Ọ nwekwara ike melite nrapado mbụ na ike njikọ nke nrapado.
4. Ngwa nke methylcellulose na ụlọ ọrụ nri
Methylcellulose, dị ka ihe mgbakwunye nri, nwere ezigbo nchekwa na nkwụsi ike na a na-ejikarị eme ihe maka ịgbakọ nri, nkwụsi ike na emulsification. Ọ nwere ike melite uto, udidi na ọdịdị nke nri, ebe ọ na-agbatị ndụ ndụ nke nri.
Thickener na stabilizer: N'ihe oriri ndị dị ka jelii, pudding, ude, ofe na ihendori, methylcellulose nwere ike ime ka ihe na-esi ísì ụtọ na-eme ka nri ahụ dịkwuo viscous na ire ụtọ. Ọ nwere ike ịmepụta colloid viscous na mmiri, gbochie stratification na mmiri ozuzo nke ihe oriri, ma melite nkwụsi ike nke ngwaahịa.
Ihe dochie abụba: Njirimara gelation thermal nke methylcellulose na-enye ya ụtọ dị ka abụba na obere okpomọkụ, enwere ike iji ya dochie abụba na nri ndị nwere obere kalori. Ọ nwere ike belata ọdịnaya abụba na-enweghị emetụta uto, na-enyere ndị na-emepụta nri aka ịmepụta ngwaahịa dị mma.
Njide mmiri: N'ime ihe oriri ndị e ghere eghe, methylcellulose nwere ike imeziwanye ikike njigide mmiri nke mgwakota agwa, gbochie mgbawa nke ikuku mmiri na-akpata, ma melite ọdịdị na ịdị nro nke ngwaahịa ahụ.
5. Ngwa nke methylcellulose na ọgwụ na ihe ịchọ mma
A na-eji Methylcellulose eme ihe n'ọtụtụ ebe na ọgwụ na ihe ịchọ mma n'ihi adịghị egbu egbu ya na ezigbo bioacompatibility.
Ngwa na ọgwụ: Na nkwadebe ọgwụ, methylcellulose nwere ike iji dị ka ihe nkedo, ihe nkiri mbụ na disintegrant maka mbadamba nkume iji hụ na ntọhapụ na absorption nke ọgwụ dị irè. N'ime ọgwụ mmiri mmiri, enwere ike iji ya dị ka onye na-akwụsịtụ na ihe na-eme ka ọ ghara igbochi mmiri ozuzo nke ihe ndị na-arụ ọrụ.
Ngwa n'ime ihe ịchọ mma: N'ihe ịchọ mma, a na-eji methylcellulose mee ihe dị ka ihe na-esikwu ike na nkwụsi ike iji nyere ngwaahịa ndị dị ka lotions, creams, na shampoos aka ịnọgide na-enwe ezigbo udidi na nkwụsi ike. Ọ nwere ike igbochi mmanụ na mmiri stratification na-enye ngwaahịa lubrication na moisturizing mmetụta.
6. Ngwa na ụlọ ọrụ ndị ọzọ
Methylcellulose na-arụkwa ọrụ dị mkpa na ụlọ ọrụ ndị ọzọ. Dịka ọmụmaatụ, na ụlọ ọrụ na-emepụta akwụkwọ, a na-eji methylcellulose mee ihe dị ka onye na-ekesa eriri iji meziwanye otu nke pulp; na ụlọ ọrụ seramiiki, a na-eji ya dị ka ihe nkedo iji nyere aka na-ejikọta ntụ ntụ seramiiki n'oge usoro ịkpụzi; N'ime ụlọ ọrụ na-egwupụta mmanụ, a na-eji methylcellulose mee ihe dị ka ihe na-esi ísì ụtọ na mmanu maka ịkụ ala apịtị iji melite arụmọrụ na nkwụsi ike.
Methylcellulose nwere ike ịrụ ọrụ dị mkpa n'ọtụtụ mpaghara mmepụta ihe site na nhazi kemịkalụ pụrụ iche na akụrụngwa anụ ahụ. Ọkpụkpụ ya, njide mmiri, nkwụsi ike na ọrụ mmepụta ihe nkiri na-eme ka ọ bụrụ nhọrọ dị mma maka ịkwalite mmepụta mmepụta ihe. Ma ọ bụ ihe eji ewu ụlọ, mkpuchi, nri, ma ọ bụ ọgwụ, ihe ịchọ mma na ubi ndị ọzọ, methylcellulose ewetala ọganihu dị ukwuu na nkwalite na ngwaahịa na arụmọrụ ya dị mma. N'ọdịnihu, na mmepe nke teknụzụ mmepụta ihe na-aga n'ihu, atụmanya ngwa nke methyl cellulose ga-abawanye ụba.
