Ibipimo bya Sodium Carboxymethylcellulose / Cellulose ya Polyanionic

Sodium carboxymethylcellulose (CMC) na polyanionic selulose (PAC) ni ibikomoka kuri selile bikoreshwa cyane mu nganda zitandukanye, harimo ibiryo, imiti, amavuta yo kwisiga, no gucukura amavuta. Ibi bikoresho akenshi byubahiriza ibipimo byihariye kugirango byemeze ubuziranenge, umutekano, no guhora mubikorwa byabo. Hano hari bimwe mubisanzwe byerekanwa kuri sodium carboxymethylcellulose na selile ya polyanionic:

Sodium Carboxymethylcellulose (CMC):

1. Inganda zikora ibiribwa:
   • E466: Ubu ni uburyo mpuzamahanga bwo gutondekanya nimero y’inyongeramusaruro, kandi CMC ihabwa E nimero E466 na komisiyo ya Codex Alimentarius.
   • ISO 7885: Ihame rya ISO ritanga ibisobanuro kuri CMC ikoreshwa mubicuruzwa byibiribwa, harimo ibipimo byera hamwe nibintu bifatika.
2. Inganda zimiti:
   • USP / NF: Pharmacopeia yo muri Amerika / Imiterere y’igihugu (USP / NF) ikubiyemo monografiya ya CMC, igaragaza ibiranga ubuziranenge, ibisabwa kugira isuku, nuburyo bwo gupima imiti ikoreshwa.
   • EP: Pharmacopoeia yu Burayi (EP) ikubiyemo kandi monografiya ya CMC, isobanura ubuziranenge bwayo nibisobanuro byo gukoresha imiti.

Cellulose ya Polyanionic (PAC):

1. Inganda zo gucukura peteroli:
   • API Spec 13A: Ibi bisobanuro byatanzwe n'ikigo cya peteroli cya Amerika (API) bitanga ibisabwa kuri selile ya polyanionic ikoreshwa nk'inyongeramusaruro y'amazi. Harimo ibisobanuro byera, gukwirakwiza ingano yubunini, imiterere ya rheologiya, no kugenzura kuyungurura.
   • OCMA DF-CP-7: Iyi ngingo ngenderwaho, yasohowe n’ishyirahamwe ry’ibikoresho bya peteroli (OCMA), itanga umurongo ngenderwaho mugusuzuma selileyo ya polyanionic ikoreshwa mubisabwa mu gucukura peteroli.

Umwanzuro:

Ibipimo bigira uruhare runini mu kwemeza ubuziranenge, umutekano, n’imikorere ya sodium carboxymethylcellulose (CMC) na selile ya polyanionic (PAC) mu nganda zitandukanye. Kubahiriza ibipimo bifatika bifasha ababikora nababikoresha kugumya kwizerwa no kwizerwa mubicuruzwa byabo nibisabwa. Ni ngombwa kwifashisha ibipimo byihariye bikoreshwa mugukoresha CMC na PAC kugirango hagenzurwe neza ubuziranenge no kubahiriza amabwiriza.
