Ukulungiswa kwe-carboxymethyl seluplose

I-Carboxymethyl Selelose (CMC)Ngaba i-polymer ye-polymer eqinileyo ye-arlymer ethathwe kwi-sellyulose, eyi-Polysacchaackaride yeNdalo efumaneka kwiindonga zeseli ezityalo. CMC finds extensive applications in various industries including food, pharmaceuticals, cosmetics, textiles, paper, and many others due to its unique properties such as thickening, stabilizing, binding, film-forming, and water retention. Ukulungiswa kwe-CMC kubandakanya amanyathelo aliqela okuqala ukusuka ekukhutshelweni kweselpulose evela kwimithombo yendalo kulandelwe kukuguqulwa kwayo ukwazisa amaqela e-carboxymethyl.

I-1. Ukukhupha iSelUlose:
Inyathelo lokuqala kulungiselelo lwe-CMC kukukhupha i-selsulose evela kwimithombo yendalo efana ne-pulp ye-pulp, iintambo zekotoni, okanye ezinye iintsinga zezityalo. I-seluplose idla ngokufunyanwa uthotho lweenkqubo kubandakanya ukutywina, ukuhlambela, nokuhlanjululwa. Umzekelo, i-Pulp yeWood inokufumaneka ngenkqubo yokutsalwa koomatshini okanye iinkqubo zekhemikhali ezilandelwa yi-blorine okanye i-hydrogen peroxide ukuze isuse izinto ezingcolileyo kunye ne-legsin.

I-2. Ukusebenza kweSeluplose:
Nje ukuba iSeluplose ikhutshiwe, kufuneka isebenze ukuze ikwazi ukwenziwa kokuqalisa kwamaqela e-carboxymethyl. Ukwenza isebenze idla ngokufezekiswa ngokunyanga isellulose nealkali efana neSodium hydroxide (i-nah) okanye i-na2code (na2covate (na2co3) phantsi kweemeko ezilawulwayo kunye noxinzelelo. Unyango lwe-Alkali lushukumisa iintsinga zeselselose kwaye unyuse i-Intracial ngokuqhawula i-Intra kunye ne-Intermolecular Hydrogen Bonds.

I-3. I-carboxymethy
I-seluplose evulekileyo yenziwa i-carboxymethythy rection apho amaqela e-carboxymethyl (-C2cooh) aziswa kwi-hydroxyl yamaqela eeselula. Le ndlela yokuphendula idla ngokwenza ngokusabela kwiselpulose evunyiweyo kunye ne-sodium monoclocetate (SMCA) phambi kwe-alkaline ye-alkali ene-sodium hydroxide (NaOH). Indlela yokusabela inokumelwa ngolu hlobo lulandelayo:

I-seluplose + chlorocetic acid → i-carboxeyymethyl seluplose

Iimeko zokuphendula kubandakanya ubushushu, ixesha lokuphendula, ukugxila kwe-Regegents, kwaye i-PH ilawulwa ngononophelo ukuqinisekisa isivuno esiphezulu kunye nenqanaba elifunwayo le-PLUITE YAMAQHAMBA

4. Ukungathathi cala kunye nokuhlamba:
Emva kwe-carboxymethyth yokuphendula, i-carboxymethyl seluplose ingathathi cala ukususa i-Alkali egqithisileyo kunye ne-chlorocetic engekhoyo. Oku kufezekiswa ngokuhlamba imveliso ngamanzi okanye isisombululo se-dilute acid kulandelwe ngokugcwalisa ukwahlulahlula i-CMC eqinileyo evela kumxube wokuphendula.

5. Ukucocwa:
I-CMC ehlanjululwe ihlanjwe ngamaxesha amaxesha amaninzi ukuba isuse ukungazithembi njengeetyus, ukuphinda-phinda okungekho ngqiqweni, kunye neemveliso. Ukuqulunqa okanye ukuqina kunokuqeshwa ukwahlula i-CMC ecocekileyo ukusuka kumanzi okuhlamba.

6. Ukomisa:
Okokugqibela, i-carboxymethyl sellyulose yomiswe ukususa umswakama wentsalela kwaye ifumane imveliso oyifunayo kwi-powder okanye igranti yegranti. Ukomisa kunokufezekiswa kusetyenziswa iindlela ezahlukeneyo ezinje ngokumisa umoya, ukonakalisa i-vacuum, okanye ukutshisa ukusoma ngokuxhomekeka kwiimpawu ezinqwenelekayo zemveliso efunekayo.

I-7. Uhlobo lolawulo lomgangatho:
EyomileyoCmcImveliso iphantsi kweendlela ezahlukeneyo zokuguqulelwa ezinje ngenguqu ye-Inrad Spectroscopy (fir), i-birner ye-nyclear), kunye nemilinganiselo ye-NMRMaic), kunye nemilinganiselo ye-NMREART yokuqinisekisa ubunzima bemichiza, isidanga sokufakwa endaweni, nobunzima. Iimvavanyo zolawulo lomgangatho zenziwa ukuqinisekisa ukuba imveliso ihlangabezana ngqo ngqo kusetyenziswa izicelo zayo.

Ukulungiswa kwebhokisi yebhokisi ye-carboxymethyl selliese kubandakanya amanyathelo amaninzi ekukhutshelwa kweselokhinase ukusuka kwimithombo yendalo, ukusebenza, ukucocwa, ukucocwa, ukomisa, kunye nophawu. Inyathelo ngalinye lifuna ulawulo ngononophelo lweemeko zokuphendula kunye neeparamitha ukufezekisa isivuno esiphezulu, isidanga esinqwenelekayo sokufakwa endaweni, kunye nomgangatho wemveliso yokugqibela. I-CMC yi-polymer esetyenziswe ngokubanzi ngezicelo ezahlukileyo ngenxa yepropathi yakhe eyahlukileyo kunye nokungasebenzi kakuhle.
