Imiterere ya selulose ya sodium carboxymethyl

Selulose ya sodium carboxymethylni eteri ya cellulose ya anionic ifite ifu y'umweru cyangwa umuhondo muto ifite fibrous cyangwa ifu yera mu buryo busa, nta mpumuro, nta buryohe kandi ntabwo ari uburozi; yoroshye gushonga mu mazi akonje cyangwa ashyushye kugira ngo ikore umuti ubonerana ufite ubukana runaka, umuti ni utari mu mazi cyangwa ufite alkaline gato; ntushonga mu bintu by'umwimerere nka ethanol, ether, isopropanol, acetone, nibindi, ishonga mu 60% bya ethanol cyangwa acetone irimo amazi.

Ni hygroscopic, ihamye ku mucyo n'ubushyuhe, ubushyuhe buragabanuka uko ubushyuhe bwiyongera, umuti uba uhamye ku gipimo cya PH cya 2-10, igipimo cya PH kiri munsi ya 2, hari imvura ikomeye, naho igipimo cya PH kiri hejuru ya 10, ubushyuhe buragabanuka. Ubushyuhe bwo guhindura ibara ni 227℃, ubushyuhe bwa karuboni ni 252℃, kandi ubushyuhe bw'amazi bwa 2% ni 71mn/n.

Iyi ni yo miterere ifatika ya selulose ya sodium carboxymethyl, ihagaze ite?

Imiterere ifatika ya selulose ya sodium carboxymethyl irahamye cyane, bityo ikaba ifite ifu y'umweru cyangwa umuhondo iramba. Imiterere yayo idafite ibara, impumuro kandi idafite uburozi ishobora gukoreshwa mu bihe bitandukanye, nko mu nganda z'ibiribwa, inganda z'imiti, n'ibindi; Muri icyo gihe, ifite ubushobozi bwo gushonga neza kandi ishobora gushonga mu mazi akonje cyangwa mu mazi ashyushye kugira ngo ikore gel, kandi umuti ushongeshejwe ni udafite aho ubogamiye cyangwa ufite alkaline nkeya, bityo ishobora gukoreshwa mu buryo butandukanye kandi ikazana ingaruka nziza.

Kubera ko selulosi ya sodium carboxymethyl ishongesha cyane, ishobora gukoreshwa mu bihe byinshi mu musaruro no mu buzima. Birumvikana ko imiterere yayo ihamye cyane, kandi inyungu ishobora kuzana zizagaragara cyane, bigatuma twishimira ibyiyumvo bitandukanye.
