Chii chinonzi sodium carboxymethyl cellelose?

CarboxyMethylcellose (CMC) ishandare yemakemikari uye yakashandiswa nemakemikari anowana zvikumbiro zviri mumaindasitiri akasiyana siyana nekuda kwezvivakwa zvaro zvakasarudzika. Iyi polymer inotorwa kubva ku cellulose, polymer yakasikwa inowanikwa mumasero emaruva ezvirimwa. CarboxyMethylcellose iri yakanyorwa nemakemikari yekugadziridzwa kwemheremalose kuburikidza nekutanga kweCarbolmeymeymethyl mapoka emapoka, ayo anokwazisa mvura yayo-solubility.

Molecular chimiro uye synthesis

CarboxyMethylEllose inovheneka cellulose chain ine carboxymethyl mapoka (-ch2-cooh) yakabatanidzwa kune mamwe mahydroxyl mapoka paGlucose zvikamu. Iyo Synthesis yeCMC inosanganisira maitiro eCellulose neChloroacetic acid, zvichikonzera kutsiva kwehydrogen maatomu pane cellucose ketani ine carbolmeymethyl mapoka emapoka ane carbolmethyl. Dhigirii rekutsiva

Zvimiro zvemuviri uye zvemakemikari

1. Solubility: Chimwe chezvakakosha zveCMC ndirwo rwemvura-salubility, ichiita kuti iite anonyanya kukonzeresa mumiriri mumvura mhinduro. Iyo degree rekutsiva rinobata iyo solubility, ine yakakwira DS inotungamira kuwedzera mvura yekuwedzera.
2. Viscosity: Carboxymethylcellose inokosheswa nekugona kwayo kuwedzera iyo visikoka yezvinwiwa. Izvi zvinoita kuti ive chinhu chakajairika mune zvakakura zvigadzirwa, zvakadai sezvinhu zvekudya, mishonga yechikafu, uye zvigadzirwa zvekuchengeta pachako.
3. Firimu-Kugadzira Zvivakwa: CMC inogona kuumba mafirimu kana yakaoma, inopa iyo application mumaindasitiri emaindasitiri emagetsi akaonda, anochinjika anodiwa.
4. Ion kuchinjana: CMC ine ion exchanges Properties, uchibvumira kuti ifambe neINS mumhinduro. Ichi chivakwa chinowanzo kubatwa mumaindasitiri kunge kurapwa kwemafuta nekurohwa kwemarara.
5. Kugadzikana: CMC yakagadzikana pasi pehuremu hwakawanda hwePP mamiriro, kuwedzera kune raisanganisira raishandiswa kwazvo mune dzakasiyana mashandisirwo.

Zvishandiso

1. Indasitiri yechikafu:

• Kukoshesa Agent: CMC inoshandiswa seyekuwedzera mumiriri mune dzakasiyana siyana chikafu zvigadzirwa, kusanganisira masaga, zvipfeko, uye zvigadzirwa zvemukaka.
• STabilizer: Inodzora emultions mune zvigadzirwa zvekudya, kudzivirira kuparadzaniswa.
• Tumira mameseji Modifier: CMC inosimudzira iyo yekunyora uye muromo kwechimwe chinhu chikafu.

2. Mishonga:

• Binder: CMC inoshandiswa seyekuchinjika mumapiritsi emishonga, kubatsira kubata izvo zvinosanganiswa pamwechete.
• Kumiswa Mumiriri: Inoshandirwa mumishonga yemvura kudzivirira kugadzirisa zvimedu.

3. Zvigadzirwa zvega zvega:

• Viscosity Modifier: CMC inowedzerwa kune cosmetics, shampoos, uye midziyo yekugadzirisa zvavakatarisana nayo uye kuvandudza chimiro chavo.
• Stabilizer: inokanganisa emulsions mune cosmetic mafomu.

4. Indasitiri yepepa:

• Surure Singigies Agent: CMC inoshandiswa mupepa repepa kuti dzivandudze nzvimbo dzepepa, dzakadai sekunyorova uye kudhinda.

5. Textile Indasitiri:

• Kubata mumiririri: CMC inoshandiswa kune mafaira kuti uvandudze zvivakwa zvavo zvekusiya uye kusimudzira simba remucheka wakakonzera.

6. Kudhiraini Mafuta:

• Fluid kurasikirwa kwekutonga mumiririri: CMC inoshandirwa mumvura inodhonza kudzora kurasikirwa kweFluid, kuderedza njodzi yekusagadzikana kwakanaka.

7. Kurapa Kwemambotara:

• Floculant: CMC zviito seinobuda kuti uunganidze zvidimbu zvakanaka, uchiita kubviswa kwavo mukureba kwekurapa kwekurapa.

Kufunga kwezvakatipoteredza

Carboxymethylcellose inowanzoonekwa seyakachengeteka kushandiswa mune dzakasiyana siyana application. Semunhu cellulose anobva, iri biodegradable, uye kukanganisa kwayo kwezvakatipoteredza kwakadzikira. Nekudaro, zvakakosha kuti ufunge nezve tsoka dzakavimbika dzekugadzirwa kwayo uye kushandiswa.

Mhedziso

Carboxymethylcellose inzvimbo inoverengeka uye yakakosha polymer ine yakapararira yekushandisa maindasitiri akasiyana. Yayo yakasarudzika inosanganiswa yezvivakwa, kusanganisira yemvura solubility, kugona kwakasimba, uye kugadzikana, kunoita chinhu chakakosha pane zvakavanzika muzvigadzirwa zvakasiyana siyana. Maindasitiri anoramba achitsvaga mhinduro dzakasimba uye dzakashanda, basa rezvakarukwa, uye kutsvagurudza kunogona kufumura zvikumbiro zvitsva zveichi chinoshamisa polymer.
