Kugadzirira kweCarboxyMethyl Cellose

Carboxymethyl cellose (cmc)Inoshamisa yemvura-yakadzvanywa-inodzora-soluble polymer yakawanikwa kubva ku cellulose, inova chisikwa chechipfuva chakawanikwa mumasero emasero. CMC inowana akawanda ekushandisa mumaindasitiri akasiyana siyana kusanganisira chikafu, mishonga, zvinyorwa, pepa, kudzikisira, kusunga, kusunga, uye kuchengetwa kwemvura, uye kuchengetwa kwemvura. Kugadziriswa kweCMC kunosanganisira nhanho dzinoverengeka kutanga kubva pakurwiswa kwemasekonzi kubva kune zvakasikwa zvinyorwa zvinoteverwa nekugadziridzwa kwaro kusuma carboxymethyl mapoka ezvivakwa.

1. Kubvisa Cellulose:
Nhanho yekutanga mukugadzirira kweCMC ndeyekupedzisira kwemasangano kubva kune zvakasikwa mashura akadai sehuni dzemapuranga, machira ekotoni, kana mamwe mafaera. Iyo cellulose inowanzo kuwanikwa kuburikidza neyekutevedzana kwemaitiro kusanganisira kuburitsa, kusviba, uye kucheneswa. Semuenzaniso, danda remvura rinogona kuwanikwa nemuchina kana makemikari proping maitiro akateverwa nekubuda neClorine kana hydrogen peroxide kubvisa kusvibiswa uye lignin.

2. Activation of cellulose:
Kamwe cellulose inobviswa, inoda kuitwa kuti itange kufambisa iyo yekutanga carboxymethyl mapoka emapoka. Active Alkali kurapwa kunopaza cellulose macabers uye kunowedzera yavo yekugadzirisa nekutyora intra uye intermolecular hydrogen zvisungo.

3. CarboxyMethyation Reaction:
Iyo yakagadziriswa cellulose inoshandiswa kuiswa kuCarboxymethylation Kuita uku kunowanzoitwa nekuita iyo activate cellulose neSodium monochloroacetate (SMCA) pamberi peiyo alkaline Catalyst yakadai seSodium Hydroxide (Naoh). Maitiro acho anogona kumiririrwa seinotevera:

Cellulose + chloroacetic acid → carboxymethyl cellose + nacl

Mamiriro ezvinhu ekuita anosanganisira tembiricha, maitiro ekutsikisa, kusunganidzwa kwemareji ekudzorwa, dns) iyo inoreva iyo nhamba yepakati yeCarboxymethyl mapoka eClucose

4. Kusaruramisa nekugeza:
Mushure meCarboxyMethylation Reaction, iyo inokonzeresa carboxymethyl cellery haina kurariswa kubvisa yakawandisa Alkali uye isingaenderane necirocetic acid. Izvi zvinowanzoitika nekushambidza chigadzirwa nemvura kana dhidhi acid mhinduro ichiteverwa neFiltiration kuti utsaure yakasimba cmc kubva kumisangano yekuita.

5. Kunatswa:
Iyo CMC yakanatswa yasukwa nemvura kakawanda kuchibvisa kusvibiswa senge munyu, dzinza dzisina kujairika, uye ne-zvigadzirwa. Filtration kana centrifugation inogona kunge ichishandiswa kupatsanura iyo yakacheneswa cmc kubva kumvura yekugeza.

6. Kuomesa:
Pakupedzisira, iyo yakacheneswa carboxymethyl cellener yakaoma kubvisa yakasara kunyorova uye kuwana chigadzirwa chaunoda muchimiro chemagetsi chakaoma kana granules. Kuomesa kunogona kuitwa uchishandisa nzira dzakasiyana-siyana dzakadai sekuomesa kwemhepo, kana kupfira kuomesa zvichienderana nehunhu hwaunoda chigadzirwa.

7. Chimiro uye Hwakanaka Kudzora:
AkaomeswaCmcChigadzirwa chinoiswa pasi pehunhu hwakasiyana-siyana hunoshanduka-shanduko infrered spectrarecopy (FTRI war Mhando yekutonga inoitwawo inoitwa kuti ive nechokwadi chekuti chigadzirwa chinosangana nezvinotaurwa zvinodiwa kuti zviitwe zvekushandisa.

Kugadziriswa kweCarboxyMethyl Cellese kunosanganisira matanho akati wandei kusanganisira kuongororwa kwemasekonzi kubva kune zvakasikwa, kusarerekera, kusarerekera, kuchenesa, uye chimiro. Nhanho yega yega inoda kunyatso kutonga kwemamiriro ezvinhu uye paramita kuti uwane yakakwirira gohwo, inodiwa degree rekutsiva, uye mhando yechigadzirwa chekupedzisira. CMC iri polymer yakashandiswa zvakanyanya neakasiyana-siyana zvikumbiro nekuda kwezvivakwa zvaro zvakasarudzika uye zvinowedzera.
