1. Sodium Carboxymethyl Cellulose
Icapiro ryimyitozo ngororamubiri ni inkomoko hamwe na ether yabonetse binyuze muburyo bwo guhindura imiti ya selile. Nibishishwa byamazi ashobora gushonga mumazi akonje namazi ashyushye. Igisubizo cyacyo cyamazi gifite imirimo yo guhuza, kubyimba, gutatanya, guhagarika no gutuza.
Icapiro ryimyororokere nigicuruzwa cya sodium carboxymethyl selulose hamwe na etherification yo hejuru. Inzira idasanzwe ituma itsinda ryibanze rya hydroxyl ryasimbuwe rwose, kugirango wirinde kwitwara hamwe n amarangi akora.
Nkuko umubyimba mwinshi wo gucapa, paste yerekana neza irashobora guhagarika ubwiza bwayo, kunoza ubwiza bwa paste, kongera ubushobozi bwa hydrophilique y irangi, gukora irangi ryamabara no kugabanya itandukaniro ryamabara; icyarimwe, mugikorwa cyo gukaraba nyuma yo gucapa no gusiga irangi, igipimo cyo gukaraba kiri hejuru, Umwenda wumva woroshye gukoraho.
2. Kugereranya ibiranga ibiranga reaction yo gucapa na sodium alginate
2.1
Ugereranije na sodium alginate, paste yandika yandika ifite ububobere buke, bwaba bukoreshwa bwonyine cyangwa bufatanije nibindi binini, burashobora kugabanya neza igiciro cya paste; mubisanzwe, icapiro ryimikorere ikora Igipimo ni 60-65% gusa ya sodium alginate.
2.2 Umusaruro wamabara kandi wumve
Umusaruro wamabara ya paste yo gucapura yateguwe hamwe nogucapura neza nkuko byabyimbye bihwanye na sodium alginate, kandi umwenda wumva woroshye nyuma yo kubishaka, ibyo bikaba bihwanye nibicuruzwa bya sodium alginate.
2.3 Shira ituze
Sodium alginate ni colloid isanzwe, ifite kwihanganira nabi mikorobe, igihe gito cyo kubika amabara, kandi byoroshye kwangirika. Ihungabana ryibicuruzwa bisanzwe bya sodium carboxymethyl selile iruta kure iyindi ya sodium alginate. Ibicuruzwa byacapishijwe neza byatejwe imbere nuburyo bwihariye, kandi kurwanya electrolyte biruta ibicuruzwa bisanzwe bya sodium carboxymethyl selile. Mugihe kimwe, zifite aho zihurira nabafasha ba chimique n amarangi, kandi ntabwo byoroshye kwangirika no kwangirika mugihe cyo kubika. Imiti ihamye ni nziza kuruta sodium alginate.
2.4 Rheologiya (yuzuzanya)
Sodium alginate na CMC byombi ni amazi ya pseudoplastique, ariko sodium alginate ifite ububobere buke bwububiko hamwe nagaciro gakomeye ka PVI, kubwibyo ntibikwiriye ko icapiro ryizengurutse (rinini), cyane cyane icapiro rya meshi mesh; Ibicuruzwa byacapwe byoroshye bifite ibyubaka bihanitse, agaciro ka PVI ni 0.5, byoroshye gucapa neza imirongo n'imirongo. Ihuriro rya sodium alginate hamwe nigikorwa cyo gucapa kirashobora kuzuza ibisabwa byinshi bya rheologiya yo gucapa
