Sodium Carboxymethyl Cellulose Gukoresha Inganda Isesengura

Ibicuruzwa byo mu rwego rwo hejuru bya sodium carboxymethyl selulose ni polyanionic selulose (PAC), nayo ni anionic selulose ether, ifite impamyabumenyi ihanitse yo gusimbuza no gusimburana, urunigi rugufi na molekile ihamye. , bityo rero irwanya umunyu mwiza, irwanya aside, irwanya calcium, irwanya ubushyuhe bwinshi nibindi bintu, kandi imbaraga zayo nazo zongerewe imbaraga. Ikoreshwa mu nganda zose aho carboxymethyl selulose ishobora gukoreshwa, itanga ituze ryiza kandi yujuje ibisabwa. Ibisabwa. Carboxymethyl selulose ni ifu yera idafite ubumara kandi idafite impumuro nziza kandi ikora neza kandi irashobora gushonga mumazi. Igisubizo cyacyo cyamazi nikidafite aho kibogamiye cyangwa alkaline kibonerana cyamazi ya viscous, gishonga mubindi bishishwa byamazi hamwe na resin, bitangirika Birashobora gukoreshwa mumashanyarazi kama nka Ethanol. CMC irashobora gukoreshwa nkibifatika, kubyimbye, guhagarika ibikorwa, emulifiseri, gutatanya, stabilisateur, agent ingana, nibindi.
Sodium carboxymethyl selulose nigicuruzwa gifite umusaruro mwinshi, gikoreshwa cyane kandi cyoroshye cyane muri ethers ya selile, bakunze kwita "monosodium glutamate yinganda".
1. Ikoreshwa mu gucukura no gucukura amariba ya peteroli na gaze gasanzwe.
CMC ifite ubukonje bwinshi kandi murwego rwo hejuru rwo gusimbuza ikwiranye nicyondo gifite ubucucike buke, na CMC ifite ubukonje buke hamwe nubunini bwo gusimbuza ikwiranye nicyondo gifite ubucucike bwinshi. Guhitamo CMC bigomba kugenwa ukurikije ibihe bitandukanye nkubwoko bwibyondo, akarere nuburebure bwimbitse.
2. Ikoreshwa mu nganda z’imyenda, icapiro n’irangi. Inganda zikoresha imyenda zikoresha CMC nkibikoresho bingana ubunini buke bw ipamba, ubwoya bwa silike, fibre chimique, bivanze nibindi bikoresho bikomeye;
3. Ikoreshwa mu nganda zimpapuro CMC irashobora gukoreshwa nkimpapuro zorohereza impapuro nogukora ingero zinganda. Ongeraho 0.1% kugeza 0.3% CMC kuri pulp irashobora kongera imbaraga zingutu zimpapuro 40% kugeza kuri 50%, byongera gucikamo ibice 50%, kandi bikongerera inshuro 4 kugeza 5.
4. CMC irashobora gukoreshwa nka adsorbent yumwanda iyo yongewe kumashanyarazi; imiti ya buri munsi nkinganda zinyoza amenyo CMC glycerine yumuti wamazi ikoreshwa nkibishishwa byinyo yinyo; uruganda rwa farumasi rukoreshwa nkibibyimbye na emulisiferi; Umuti wamazi wa CMC urabyimbye kandi ukoreshwa mugutunganya amabuye y'agaciro, nibindi.
5.
6. Yakoreshejwe mubwubatsi kugirango atezimbere amazi n'imbaraga
7. Ikoreshwa mu nganda zibiribwa. Inganda zikora ibiryo zikoresha CMC zifite urwego rwo hejuru rwo gusimbuza nkibyimbye bya ice cream, ibiryo byafunzwe, isafuriya itetse vuba, hamwe na stabilisateur ifuro ya byeri, nibindi.
8. Uruganda rwa farumasi ruhitamo CMC hamwe nubukonje bukwiye nkibikoresho bya tablet, bidahwitse, kandi bihagarika umukozi kugirango ahagarare.

Ibikoresho byumye byubaka ibikoresho byongeweho:
Irashobora gukoreshwa mumashanyarazi ya latx ikwirakwizwa, hydroxypropyl methylcellulose, micropowder ya polyvinyl alcool, fibre polypropilene, fibre yinkwi, inhibitori ya alkali, imiti yica amazi, hamwe na retarder.

PVA n'ibikoresho:
Inzoga za polyvinyl, bactericide antiseptic, polyacrylamide, sodium carboxymethyl selulose, inyongeramusaruro.

Ibifatika:
Urukurikirane rwa latex yera, VAE emulsion, styrene-acrylic emulsion hamwe ninyongera.

Amazi:
1.4-Butanediol, tetrahydrofuran, acetate ya methyl.

Ibyiciro byiza byibicuruzwa:
Anhydrous Sodium Acetate, Diacetate ya Sodium
