Okwu Mmalite Ngwaahịa CMC maka Tapawa Mbipụta Reactive

1. Sodium Carboxymethyl Cellulose
Tapawa obibi akwụkwọ na-arụ ọrụ bụ ihe ether a na-enweta site na mgbanwe kemịkalụ nke cellulose eke.Ọ bụ gluu na-agbaze mmiri nke nwere ike ịgbaze na mmiri oyi na mmiri ọkụ.Ngwọta mmiri ya nwere ọrụ nke njikọta, ịgbasa, ịgbasa, kwụsịtụ na nkwụsi ike.

Tapawa mbipụta na-arụ ọrụ bụ ngwaahịa nke sodium carboxymethyl cellulose nwere ogo dị elu nke etherification.Usoro pụrụ iche na-eme ka otu hydroxyl bụ isi ya dochie kpamkpam, ka ọ ghara imeghachi omume na agba agba.

Dị ka thickener nke na-ebi akwụkwọ tapawa, reactive ebipụta mado nwere ike mee ka viscosity kwụsie ike, melite fluidity nke mado, welie hydrophilic ike nke agba, mee ka ịcha mma na-ebelata agba iche;n'otu oge ahụ, na usoro ịsa ahụ mgbe e bipụtachara na ịcha akwa, ọnụ ọgụgụ ịsa ahụ dị elu, ákwà ahụ na-adị nro na-emetụ aka.

2. Ntụle nke njirimara nke reactive ebipụta mado na sodium alginate
2.1 Tapawa ọnụego

E jiri ya tụnyere sodium alginate, reactive printing paste nwere viscosity dị elu, ma a na-eji ya naanị ma ọ bụ na-ejikọta ya na ndị ọzọ na-ekpo ọkụ, ọ nwere ike belata ọnụ ahịa nke mado;na-emekarị, na-arụ ọrụ na-ebi akwụkwọ mado Usoro onunu ogwu bụ naanị 60-65% nke sodium alginate.

2.2 Agba mkpụrụ na mmetụta

Ụdị agba nke mpempe akwụkwọ a kwadebere ya na mpempe akwụkwọ reactive dị ka thickener dabara na nke sodium alginate, na ákwà ahụ na-adị nro mgbe ọ nwụsịrị, nke ya na ngwaahịa sodium alginate tapawa.

2.3 Tapawa nkwụsi ike

Sodium alginate bụ colloid eke, nke na-adịghị anabata microorganisms, obere oge nchekwa nke mado agba, ma dị mfe imebi.Nkwụsi ike nke ngwaahịa sodium carboxymethyl cellulose nkịtị dị elu karịa nke sodium alginate.A na-eme ka ngwaahịa ndị na-ebi akwụkwọ na-arụ ọrụ dị mma site na usoro pụrụ iche, na nguzogide electrolyte ha dị mma karịa ngwaahịa sodium carboxymethyl cellulose nkịtị.N'otu oge ahụ, ha nwere ezigbo ndakọrịta na ihe enyemaka kemịkalụ na agba, ọ dịghịkwa mfe imebi ma mebie n'oge nchekwa.Nkwụsi ike kemịkalụ dị mma karịa sodium alginate.

2.4 Rheology (mmekọrịta)

Ma sodium alginate na CMC bụ mmiri mmiri pseudoplastic, ma sodium alginate nwere obere viscosity nhazi na uru PVI dị elu, n'ihi ya, ọ dịghị adabara maka mbipụta ihuenyo gburugburu (flat), karịsịa akwụkwọ ntanetị elu;reactive ebipụta mado ngwaahịa nwere elu structural viscosity, PVI uru bụ banyere 0.5, mfe ibipụta doro anya ụkpụrụ na ahịrị.Nchikota nke sodium alginate na-arụ ọrụ na-ebi akwụkwọ mado nwere ike izute ọzọ rheological chọrọ nke obibi akwụkwọ mado
