Ịghọta Methylcellulose:
Methylcellulose bụ ihe sitere na cellulose, polymer eke dị na osisi. Site na mgbanwe kemịkalụ, a na-emepụta methylcellulose, na-enye ya ihe pụrụ iche dị ka:
Ọkpụkpụ: Methylcellulose nwere ike ịbawanye viscosity nke ngwọta nke ọma, na-eme ka ọ baa uru na ngwa chọrọ ihe ndị na-eme ka ike sie ike.
Njide mmiri: Ọ na-egosipụta ọmarịcha njide mmiri, dị oke mkpa maka idobe mmiri na ngwaahịa dị iche iche.
Nhazi ihe nkiri: Methylcellulose nwere ike ịmepụta ihe nkiri mgbe a mịrị amị, na-eme ka ọ baa uru na mkpuchi na adhesives.
Nkwụsi ike: Ọ na-eme ka emulsions na suspensions guzosie ike, na-egbochi nkewa nke akụkụ.
Ngwakọta Methylcellulose:
1. Ịhọrọ ụdị ziri ezi:
Methylcellulose dị na ọkwa dị iche iche na viscosities, dabere na ngwa a chọrọ. Họrọ ụdị kwesịrị ekwesị dabere na mkpa gị, na-atụle ihe ndị dị ka viscosity chọrọ, njigide mmiri, na nkwụsi ike okpomọkụ.
2. Ịkwadebe Ngwọta:
Usoro ịgwakọta na-agụnyekarị igbari methylcellulose ntụ ntụ n'ime mmiri. Soro usoro ndị a maka ịkwadebe ngwọta:
a. Ị̀tụ̀tụ̀: tụọ ọnụ ọgụgụ achọrọ nke methylcellulose ntụ ntụ n'ụzọ ziri ezi site na iji ọnụ ọgụgụ.
b. Okpomọkụ mmiri: Ọ bụ ezie na methylcellulose nwere ike ịgbaze na mmiri oyi na mmiri ọkụ, iji mmiri ọkụ (ihe dị ka 40-50 Celsius) nwere ike ime ka usoro mgbasa ahụ dịkwuo ngwa.
c. Na-agbakwunye Methylcellulose: Jiri nwayọ fesa ntụ ntụ methylcellulose n'ime mmiri ka ị na-akpalite n'ihu iji gbochie ịchịkọta.
d. Ịgwakọta: Gaa n'ihu na-akpalite ruo mgbe methylcellulose ntụ ntụ gbasasịa kpamkpam na ọ dịghị lumps fọdụrụ. Usoro a nwere ike were nkeji ole na ole.
e. Oge ezumike: Kwe ka ngwọta ahụ zuru ike maka ihe dịka nkeji 30 iji hụ na hydration zuru oke na mmepe viscosity.
3. Na-agbanwe agbanwe:
Dabere na nkwekọ achọrọ nke ngwaahịa ikpeazụ, ị nwere ike ịhazigharị ntinye nke methylcellulose na ngwọta. Maka ịdị nhịahụ siri ike, mụbaa ọnụọgụ methylcellulose, ebe maka ịdị nro dị nro, jiri mmiri ọzọ gbanye ihe ngwọta ahụ.
4. Atụmatụ okpomọkụ:
Ihe ngwọta methylcellulose na-egosipụta viscosity dabere na okpomọkụ. Okpomọkụ dị elu na-ebelata viscosity, ebe okpomọkụ dị ala na-abawanye ya. Tụlee ngwa e zubere ma mezie okpomọkụ nke ngwọta ya ka ọ wee nweta viscosity achọrọ.
5. Ịgwakọta ya na ihe ndị ọzọ:
Mgbe ị na-etinye methylcellulose n'ime usoro nwere ihe ndị ọzọ, hụ na agwakọta nke ọma iji nweta ịdị n'otu. Nke a dị mkpa karịsịa na nri na ngwa ọgwụ iji hụ na nhazi na arụmọrụ na-agbanwe agbanwe.
Ntuziaka ịgwakọta ngwa-ngwa:
A. Ngwa nri:
Methylcellulose na-ahụta ojiji a na-ejikarị eme ihe na ụlọ ọrụ nri maka ebumnuche dị iche iche, gụnyere sọstị na-akpụ akpụ, ụfụfụ na-eme ka ọ kwụsie ike, na ịmepụta gels. Soro ntuziaka ndị a maka ngwa nri nri:
Nkwalite ederede: Jiri nleba anya dị iche iche nke methylcellulose nwalee iji nweta udidi a chọrọ na mmetụta ọnụ na efere.
Oge hydration: Kwe ka oge hydration zuru oke maka ngwọta methylcellulose tupu itinye ya n'ime ntụziaka iji hụ na ihe na-eme ka ọ dị mma.
Njikwa okpomọkụ: Na-achịkwa okpomọkụ n'oge usoro nri, n'ihi na oke okpomọkụ nwere ike imebi viscosity nke ngwọta methylcellulose.
B. Ngwa ọgwụ:
N'ụdị usoro ọgwụ, methylcellulose na-eje ozi dị ka onye na-ekekọta, ihe na-agbasa, ma ọ bụ onye ntọhapụ na-achịkwa. Tụlee ihe ndị a mgbe ị na-agwakọta methylcellulose maka iji ọgwụ eme ihe:
Mbelata nha nke urughuru: Gbaa mbọ hụ na a na-egwe ọka methylcellulose nke ọma iji kwado mgbasa otu na mgbasa na usoro.
Nnwale ndakọrịta: Mepụta ọmụmụ ndakọrịta na ihe ndị ọzọ na-eme ihe na ihe ndị na-arụ ọrụ iji hụ na nkwụsi ike na ịdị mma nke ngwaahịa ọgwụ ikpeazụ.
Nrube isi n'usoro iwu: Soro ntuziaka na ụkpụrụ na-achịkwa iji methylcellulose na usoro ọgwụ.
C. Ihe eji ewu ụlọ:
A na-eji Methylcellulose eme ihe n'ihe owuwu dị ka ngwa agha, plasta, na adhesives taịlị maka njide mmiri na ihe na-eme ka ọ sie ike. Tụlee ihe ndị a mgbe ị na-agwakọta methylcellulose maka ngwa owuwu:
Njikwa na-agbanwe agbanwe: Gbanwee ntinye nke methylcellulose na ngwọta iji nweta nkwekọ achọrọ na ịrụ ọrụ nke ihe owuwu.
Ngwa Ngwakọta Ngwakọta: Jiri akụrụngwa agwakọta kwesịrị ekwesị, dị ka igwekota paddle ma ọ bụ ngwa ngwa igwe, iji hụ na mgbasa nke methylcellulose nke ọma na nhazi ahụ.
Nkwanye mma: Mejuputa usoro njikwa mma iji nyochaa arụmọrụ nke ihe owuwu nke nwere methylcellulose, gụnyere ike adhesion, mgbochi mmiri, na ịtọ oge.
Akpachara anya maka nchekwa:
Mgbe ị na-ejikwa methylcellulose, debe ihe nchekwa nchekwa ndị a iji belata ihe egwu:
Ngwa Nchekwa: Yiri akụrụngwa nchedo nkeonwe dabara adaba, gụnyere uwe aka na enyo nchekwa, iji gbochie mkpasu iwe anụ na anya.
Igwe ikuku: Gbaa mbọ hụ na ikuku ikuku zuru oke na mpaghara ngwakọta iji gbochie iku ume nke irighiri ikuku.
Nchekwa: Chekwaa ntụ ntụ methylcellulose n'ebe dị jụụ, nke kpọrọ nkụ na-esi na ebe okpomọkụ na mmiri na-esi enweta iji gbochie mmebi.
Ntufu: Tụfuo ngwaahịa methylcellulose ejighi ya ma ọ bụ mebie ya dịka ụkpụrụ na ụkpụrụ mpaghara siri dị.
Mmechi:
Ma ejiri ya mee ihe na nri nri, usoro ọgwụ, ma ọ bụ ihe owuwu, usoro ịgwakọta nke ọma dị mkpa iji meghee ikike pụrụ iche nke methylcellulose. Site n'ịgbaso usoro akwadoro na nchekwa nchekwa nke edepụtara na ntuziaka a, ị nwere ike ijikwa ike nke methylcellulose na-emekọ ihe nke ọma, na-ekekọta ya na nkwụsi ike iji nweta nsonaazụ kacha mma na ọrụ gị.
