Chii chinonzi Sodium Carboxymethyl cellulose?

Carboxymethylcellulose (CMC) ikemikari inoshandiswa zvakasiyana-siyana uye inoshandiswa zvakanyanya inoshandiswa mumaindasitiri akasiyana-siyana nekuda kwehunhu hwayo hwakasiyana. Iyi polymer inobva ku cellulose, polymer yechisikigo inowanikwa mumadziro esero emiti. Carboxymethylcellulose inogadzirwa nekuchinja kwekemikari kwe cellulose kuburikidza nekuunzwa kwemapoka e carboxymethyl, izvo zvinowedzera kugona kwayo kunyungudika mumvura uye kukora.

Maumbirwo eMolekyu uye Kugadzirwa

Carboxymethylcellulose ine cheni dze cellulose dzine mapoka e carboxymethyl (-CH2-COOH) dzakabatana nemamwe mapoka e hydroxyl ari pamayuniti e glucose. Kugadzirwa kweCMC kunosanganisira kuita kwe cellulose ne chloroacetic acid, zvichikonzera kutsiviwa kwemaatomu e hydrogen pacheni ye cellulose nemapoka e carboxymethyl. Dhigirii rekutsiva (DS), iro rinoratidza huwandu hweavhareji yemapoka e carboxymethyl payuniti yega yega ye glucose, rinokanganisa hunhu hweCMC.

Zvimiro zveMuviri neMakemikoro

1. Kunyungudika: Chimwe chezvinhu zvinonyanya kukosha muCMC ndiko kunyungudika kwayo mumvura, zvichiita kuti ive chinhu chinobatsira pakukora mumvura. Kuwanda kwekuchinjana kunokanganisa kunyungudika kwayo, uye DS yakakwira inotungamira mukunyungudika kwemvura.
2. Kusimba: Carboxymethylcellulose inokosheswa nekukwanisa kwayo kuwedzera kusimba kwezvinwiwa. Izvi zvinoita kuti ive chinhu chinowanikwa muzvigadzirwa zvakasiyana-siyana, zvakaita sezvekudya, mishonga, uye zvigadzirwa zvekuchengetedza muviri.
3. Hunhu Hwekugadzira Mafirimu: CMC inogona kugadzira mafirimu kana yaoma, zvichibatsira mukushandiswa kwayo mumaindasitiri uko kunodiwa kupeta kwakatetepa uye kunochinjika.
4. Ion Exchange: CMC ine hunhu hwekutsinhana kwemaion, zvichiita kuti ikwanise kushanda nemaion mumushonga. Hunhu uhwu hunowanzo shandiswa mumaindasitiri akadai sekuchera mafuta uye kugadzirisa mvura yakasviba.
5. Kugadzikana: CMC yakagadzikana pasi pemamiriro akasiyana-siyana epH, zvichiita kuti ishande zvakasiyana-siyana mukushandiswa kwayo kwakasiyana-siyana.

Mashandisirwo

1. Indasitiri yezvekudya:

• Mushonga wekukora: CMC inoshandiswa semushonga wekukora muzvigadzirwa zvakasiyana-siyana zvekudya, zvinosanganisira muto, madhirowa, uye zvigadzirwa zvemukaka.
• Chinosimbisa: Chinosimbisa ma emulsions ari muzvigadzirwa zvekudya, zvichidzivirira kupatsanurwa.
• Chinogadzirisa Maumbirwo: CMC inovandudza maumbirwo uye kunzwa kwemuromo kwezvimwe zvekudya.

2. Mishonga:

• Chinosunga: CMC inoshandiswa sechinosunga mumapiritsi emishonga, ichibatsira kubatanidza zvinhu zviri mukati.
• Mushonga weSuspension: Unoshandiswa mumishonga yemvura kudzivirira kugadzika kwezvikamu.

3. Zvigadzirwa zveKuchengetedza Munhu:

• Chinogadzirisa Kupenya: CMC inowedzerwa muzvizoro, shampoo, uye mafuta ekuchenesa kuti igadzirise kunaka kwazvo uye kuvandudza kunaka kwazvo.
• Chinosimbisa: Chinosimbisa emulsions mumafomu ekushongedza.

4. Bhizinesi reMapepa:

• Mumiriri weSaizi yePamusoro: CMC inoshandiswa muindasitiri yemapepa kuvandudza hunhu hwepamusoro hwepepa, zvakaita sekutsetseka uye kudhindwa.

5. Indasitiri yeMachira:

• Mushonga weSaizi: CMC inoiswa pamafaibha kuti ivandudze hunhu hwavo hwekuruka uye kuwedzera simba rejira rinobuda.

6. Kuchera Oiri:

• Mushonga weKudzora Kurasikirwa neMafuta: CMC inoshandiswa mukuboorera mvura kudzora kurasikirwa kwemvura, zvichideredza njodzi yekusagadzikana kwemvura.

7. Kurapa Mvura Yakasviba:

• Flocculant: CMC inoshanda seflocculant yekuunganidza zvidimbu zvidiki, zvichiita kuti zvibviswe mukugadzirisa mvura yakasviba.

Kufunga Nezvezvakatipoteredza

Carboxymethylcellulose inowanzoonekwa seyakachengeteka kushandiswa mumhando dzakasiyana-siyana. Sechinhu chinobva mu cellulose, chinogona kuora, uye kukanganisa kwayo nharaunda kwakaderera. Zvisinei, zvakakosha kufunga nezvehuwandu hwekugadzirwa kwayo nekushandiswa kwayo nharaunda.

Mhedziso

Carboxymethylcellulose ipolymer inoshandiswa zvakasiyana-siyana uye inokosha ine mashandisirwo akapararira mumaindasitiri akasiyana-siyana. Musanganiswa wayo wakasiyana wehunhu hwayo, kusanganisira kunyungudika kwemvura, kugona kwayo kukora, uye kugadzikana, kunoita kuti ive chinhu chakakosha muzvigadzirwa zvakasiyana-siyana. Sezvo maindasitiri achiramba achitsvaga mhinduro dzinogara kwenguva refu uye dzinoshanda, basa recarboxymethylcellulose rinogona kuchinja, uye kutsvagurudza kuri kuenderera mberi kunogona kuratidza mashandisirwo matsva epolymer iyi inoshamisa.
