Shiri na Carboxymose

Carboxymose Carboxymethyl (CMC)Babban polymer ne mai narkewa daga sel, wanda shine kayan polysaccharide na halitta a cikin bangon tantanin jikin. CMC ta sami aikace-aikace masu yawa a cikin masana'antu daban daban a cikin daban-daban ciki har da abinci, kayan kwalliya, da sauransu saboda haɓakawa, ɗaure, da riƙewar ruwa. Shirye-shiryen CMC sun ƙunshi matakai da yawa daga hakar sel daga cikin hanyoyin da ke tattare da gyaran ta don gyara ƙungiyoyin Carboxymethyl.

1. Haɗin Celulose:
Mataki na farko a cikin shirye-shiryen CRC shine hakar sel na halitta kamar su ɓangaren katako, auduga, ko wasu zargin shuka. Yawancin sel na yawanci ana samun su ta hanyar jerin matakai waɗanda ciki har da jingina, batsa, da tsarkakewar. Misali, za a iya samun ɓangaren litattafan hannu ta injina ko sunadarai masu jan kunne tare da bleaching tare da chlorine ko hydrogen peroxide don cire ƙazanta da Ligntin.

2. Kunna sel:
Da zarar an fitar da sel allulose, da zarar an kunna kunna don sauƙaƙe gabatar da ƙungiyoyin Carboxymethyl. Ana samun ƙarin kunnawa ta hanyar magance pelulue tare da alkali kamar sodium carbonate (Na2CO3) a ƙarƙashin yanayin zazzabi da matsin lamba. Alkalicar alkali ya kutsa da zaruruwa na sel kuma yana kara yawan abubuwan da suka fusata ta hanyar karya hadarin ciki da kuma shaidun hydrogen.

3. CarboxyMethyhybylation:
Don haka an kunna sel mai kunnawa da carboxymethythybybyMhybyLation na Carboxymethyl ƙungiyoyi (--ch2cooh) ana gabatar da su a kan ƙungiyoyin hydroxyl na selulose. Wannan martani yawanci ana aiwatar da shi ne ta hanyar maido da sel mai kunna shi tare da sodium monochloroaceacetate (sdca) a gaban alkalenal hydroxide (Naoh). Za'a iya wakilta martani kamar haka:

Cellulose + chloroacetetic acid → carboxymeth celululose + nacl

Halin da suka yi ciki har da zazzabi, lokacin da aka dauki lokaci, da ph ana sarrafa shi a hankali don tabbatar da adadin hidimar carboxymethyletl.

4. Cikakke da wanka:
Bayan carboxymethyhybyMhybyhybyMhymation, sakamakon Carboxymulose sel nellosecyl ne ya dakatar da karar alkali da kuma chloroaceticic acid. Wannan yawanci ana samun nasara ta hanyar wanke samfurin tare da ruwa ko mafita aci aci aci aci aci aci aci aci aciba don raba m cmc daga cakuda cakuda.

5. Tsarkakewa:
Daga nan aka yi nasara da tsarkakakken cmc tare da yawancin sau da yawa don cire ƙazantu kamar kayan ado, da ba a amince da su ba, da samfurori. Ana iya amfani da tanki ko centrifugation don raba tsarkakakkiyar cmc daga ruwan wanka.

6. Drying:
A ƙarshe, sel mai tsabta carboxylulethymethymyl ne ya bushe don cire ragowar danshi da samun samfurin da ake so a cikin busassun foda ko granules. Ana iya biyan bushewa ta amfani da hanyoyi daban-daban kamar su bushewar iska, bushewa bushewar iska, ko bushewa dangane da halayen samfuran ƙarshe.

7. Halin da ingancin ingancin:
Da busheCmcAn sanya samfurin ga dabaru daban-daban na halaye kamar arties sau da yawa (ftir), da kuma daidaita tsarin sarrafawa don tabbatar da tsarin sunadarai, da kuma ingantaccen nauyi, nauyi. Hakanan ana yin gwajin inganci mai inganci don tabbatar da cewa samfurin ya cika ƙayyadaddun bayanan da ake buƙata don aikace-aikacen da aka nufa.

A shirye-shiryen Carboxymose ya ƙunshi matakai da yawa ciki har da hakar sel. Kowane mataki yana buƙatar sarrafa yanayin hi da sigogi don samun yawan amfanin ƙasa, wanda ake so na canzawa, da kuma ingancin samfurin ƙarshe. CMC ta yi amfani da polymer sosai tare da aikace-aikace daban-daban saboda na musamman kaddarorin sa.
