Sodium carboxymethyl cellose ruzivo

Sodium CarboxyMethyl Cellerose (CMC) iri polymer yakawedzera kushandiswa mumaindasitiri akawanda seyakanyanya chikafu, mushonga, zvizarisi, zvinyorwa, pepa, uye kuyerera kwemafuta. Inowanikwa nemakemikari kugadziridzwa kwemheremalose. Hunhu hwayo hwechimiro ndezvekuti mamwe mapoka ehydroxyl muCellulose Molecules anotsiviwa neCarboxymeym mapoka (-ch2cooh) uye akasanganiswa neSodium Ions

1. Chemical chimiro uye zvivakwa

Iyo yemakemikari formula ye sodium carboxymeym cellever is (c6h7o2 (o) 2ch2coona) n, iyo ine imwe solubility uye mvura yekunyora. Chimiro chayo chekutanga chikamu chetsetse chimiro chakanyorwa cellulose monomers-glucose mamorekuru. Mushure mekugadziridzwa kwemakemikari, mamwe kana ese emapoka ehydroxyl ari pamamolellose molellecoles anotsiviwa neCarboxyMeymethyl mapoka ekugadzira mamorekuru emvura ane mari yemvura ine zvakaipa. Kunyanya, iyo molecular cheni yeSodium carboxymeym Carbolose ine nhamba huru yeCarboxymeylm mapoka (-Ch2cooh), inokwanisa kupindirana nemamolekyudhi yemvura, ichipa iyo yakanaka solubility uye viscosity hunhu.

CMC ine inotevera nzvimbo dzekutanga:

Mvura Solubility: Sodium CarboxyMethyl Cellelose inogona kukurumidza kunyungudutswa mumvura kuti iite yunifomu coolid.

Viscosity: CMC Makwikwi emamiriro ekunze ane yakakwira viscosity, uye viscosity ine hukama nemanyorerwe aro uremu uye mhinduro yekugadzirisa.

Kugadzikana: CMC ine kugadzikana kwakanaka kuAcid, Alkali uye yakanyanya kupisa, asi mune yakasimba acid kana nzvimbo yakasimba, kusimba kweCMC ichaderera.

Kugadziridzwa: Nekugadzirisa iyo molecular uremu uye degree rekutsiva kweCMC, zvivakwa zvemuviri uye zvemakemikari zvinogona kudzorwa chaizvo.

2. Kugadzirira nzira

Sodium carboxymethyl Cellelose inowanzogadzirirwa nekuita cellulose uye sodium chloroacetate mune alkaline nharaunda. Matanho chaiwo ari seanotevera:

Kunamata kweCellulose: Kutanga, cellulose (senge machira fiber) kunogezwa kuti ubvise kusvibiswa.

Alkalinization Reaction: iyo cellulose cellumlose inoitwa neSodium Hydroxide Solution yekuparadzanisa iyo hydroxyl chikamu muCellulose Molecule kuti iite anoshanda cellulose sodium munyu.

Kutsiva
Kushambidza uye Kuoma: Mushure mekunge kuitwa kwapera, chigadzirwa chakashambwa nemvura kuti ubvise kusvibiswa, uye pakupedzisira wakachenesa sodium carboxym cellever inowanikwa.

3. Masango ekushandisa

Nekuda kwekunyora kwayo kwemvura solubility, kuremerwa uye kugadzikana, sodium carboxymelm cellulose inoshandiswa zvakanyanya muminda inotevera:

Indasitiri yeChikafu: Semidhi, STabilizer, emulsifier, ecing etent, etc. inowanzoitika, etcc.

Indasitiri yechechi yechechi: Semubatanidzwa, wekusunungurwa-akasunungurwa-mumiririri, kumhanyisa mumiriri uye anoshandiswa pamahwendefa, mahwendefa, magiramu emuromo, mafuta emoto, gadziriro dzepamusoro uye zvimwe zvigadziriso. Mukuwedzera, cmc inoshandiswawo seyakanakisa zvinhu zvekuvhiya uye mazino zvinhu.

Cosmetic indasitiri: Inoshandiswa mukugadzirwa kwemazamu, kirimu, shampoos, mazino uye zvimwe zvigadzirwa sedhizimusi uye stabilizer. Inogona kugadzirisa iyo visikopa yechigadzirwa uye kusimudzira ruzivo rwemushandisi.

Indasitiri yepepa: Sechirongwa chekurapa kwepepa, cmc zvinogona kuvandudza simba, kuramba kwemvura uye kudhinda kwero pepa uye kuderedza guruva pamusoro pepepa.

Kudhara kwemafuta: Munguva yekuchera mafuta, CMC inoshandiswa mukukweva kwemvura kusvika pakukanda mvura yekukwevera mvura, batsira kubvisa rockings kutenderedza kudhiraivha uye kusimbisa rusvingo rwekare.

Indasitiri yemiindana: Sechiremba wekuparadzira dhayi uye kudhinda paste anoshambadzira, cmc inogona kuvandudza kufanana kwekunyepedzera uye kunaka kwemhando.

4. Kuchengetedza uye Zvemamiriro ekunze

Sodium carboxymethyl cellerose inowanzoonekwa yakachengeteka, uye kushandiswa kwayo mukudya uye mushonga wakabvumidzwa nechikafu chemukati cheCollic uye yakakodzera mirau yenyika. Hazvina musoro kune muviri wemunhu uye hauzove uine maitiro akakosha pane zvakasikwa nharaunda, saka inoshandiswa zvakanyanya.

Nekudaro, kunyangwe CMC pachayo ine hukama hwakatipoteredza, maitiro ayo ekugadzira anogona kusanganisira kushandiswa kwemamwe makemikari reagents uye marara ekurwisa nyaya. Naizvozvo, zvakafanira kutarisisa kune zvakatipoteredza kuchengetedza matanho panguva yekugadzira maitiro kuti uderedze kubviswa kwezvinhu zvinokuvadza.

Sodium carboxymethyl cellerose is a wrongs inoshandiswa uye yakawanda polymer. Kubata kwayo, kusimbisa uye kugadzira zvivakwa zvinoita kuti zviite zvakakosha kune maindasitiri akawanda. Kubva pakudya, mushonga kuenda kuindasitiri, cmc inoitira basa rakakosha. Nekuenderera mberi kwekufambira mberi kwehunyanzvi mune ramangwana, iyo nzvimbo yekushandisa yeCMC inogona kuwedzeredzwa.
