Yintoni i-Sodium Carboxymethyl Selelose?

I-Sodium Carboxymethyl Selelose (CMC) i-quaund esetyenziswe rhoqo kwaye isetyenziswe ngokubanzi ngezicelo ezininzi kumashishini ahlukeneyo.

Intshayelelo kwi-Sodium Carboxymethyl Selelose (CMC)
I-Sodium Carboxymethyl Selelose, ihlala ifinyezwe njenge-CMC, kukuphazamiseka kwesellulose, yenye yezona gollomes ezininzi emhlabeni. I-sellyulose, iqulethe iiyunithi eziphindaphindwayo zeglucose ezidityaniswe ngu-(1 → 4) Iibhondi ze-Glycosidic, ngokuyintloko zifumaneka kwiindonga zeseli, zibonelela ngenkxaso yesakhiwo. Ihlaziywe, i-biedegraded, kwaye inganetyhefu, iyenza ibe yinto ebonakalayo yezicelo ezahlukeneyo zeshishini.

Ulwakhiwo kunye neepropathi
I-CMC iqeshelwe ngokuguqula i-selsulose ngokuphendula kweekhemikhali, apho amaqela e-hydroxyl kwi-selsulose overbnone athatyathwa njengeqela le-carboxymethyl (-Ch2-Coh). Oku kufaka endaweni yoko kuthatyathe amanyathelo okulima kwamanzi kunye nokuphuculwa kweepropathi zeRheOolog kwi-seluplose, ekwenze kube lufaneleke uluhlu lwezicelo.

Inqanaba lokufakwa endaweni (DS) libhekisa kwinani eliphakathi le-carboxymethyl kwiyunithi nganye ye-glucose kwikhonkco leselselose kwikhonkco kwaye inefuthe kwipropathi yeCMC. Iimpawu eziphakamileyo ze-DS zikhokelela ekunyukeni kokusomeleza kwamanzi kunye nokubonisa.

I-CMC ihlala ifumaneka njenge-white-whider-whider emhlophe, kunye nobuqhophololo obahlukeneyo kuxhomekeke kwisicelo sayo. Yinto engenakuthelekiswa nanto, engenantsingiselo, kwaye ayinatyhefu, iyenza ikhuseleke ekutyeni kunye neemveliso zamachiza. I-CMC iyazinza phantsi koluhlu olubanzi lweemeko ze-ps kwaye ibonise iipropathi zokwenza ifilimu.

Iindlela zemveliso
Ukuveliswa kwe-CMC kubandakanya amanyathelo aliqela:
Ukulungiswa kwe-seluplose: I-seluplose ifunyenwe kwi-Pulp Pulp, i-Cotton Lists, okanye ezinye iintsinga zezityalo. Iseli ihlanjululwe kwaye iqhekezwe kwiintsinga ezincinci ukonyusa ukuvela kwayo.

I-Etheristition Reaction: Iintsinga zeselula ezihlanjululwe ziphathwa nge-sodium hydroxide (i-nayenzayo) isebenze amaqela e-hydroxyl. Emva koko, i-monoloplocetic acid (okanye ityuwa yayo yesodium) yongezwa kumxube wokuphendula ukwazisa amaqela e-carboethyl kwi-sellosedl backbone.

Ukungathathi hlangothi kunye nokuhlamba: Emva kokuphendula kwe-ethersise, imveliso yesiphumo ayisifakelweni ne-acid ukuyiguqula ibe yifomu yesosi yesodium. I-CMC ihlanjwe ukuze isuse ukungcola kunye neemveliso.

Ukomisa kunye nokugaya: I-CMC ecocekileyo yomisiwe isuse ukufuma okugqithisileyo kwaye ihlawulwe ukufezekisa ubungakanani obufunekayo.

Ukusetyenziswa kunye nokusetyenziswa
I-Sodium Carboxymethyl Selelose ifumana izicelo ezibanzi kumashishini ahlukeneyo:
Ishishini lokutya: I-CMC isetyenziswa ngokubanzi njenge-thi choner, i-stabilizer, kunye nearhente yokugcina umswakama kwiimveliso zokutya ezinjengobisi, iimpahla ezibhakiweyo, iiseti, iisethi, iingubo, kunye nokunxiba. Iphucula ukuthungwa, kuthintela i-syneressis, kwaye iphucule umlomo kwimeko yokutya.

Amayeza: Kumzi-mveliso wamayeza, i-CMC isetyenziswa njenge-binder kwifomu yecwecwe, i-viscosity modifier kwiminquba, kunye ne-qubthant kwizisombululo ze-ophthalmic. Iqinisekisa ukuhanjiswa kweziyobisi kunye nokukhululwa okulawulwa.

Iimveliso zononophelo lobuqu: i-CMC ifakwe kwiimveliso zononophelo zobuqu ezifana ne-toothpaste, i-shampoo, kunye nefomu ye-skercare kunye nearhente yokuthambisa, i-eulsifier, kunye nearhente yefilimu.

Umzi-mveliso wePhepha: kwiPapermandus, i-CMC yongezwa kwifomu yePulp ukuphucula amandla ephepha, iipropathi ezingaphantsi, kunye nokugcinwa kweezongezo ezinjengeefilimu kunye nee-DYE. Ikwaphucula ukuntywila kwaye kunciphise uthuli ngexesha lemveliso yephepha.

Umzi-mveliso weeMpashi: I-CMC isetyenziswa kwiinkqubo zokuprintwa ze-imeyile kunye neenkqubo zokudayanisa njenge-thi chele kunye ne-binder ye-pigment. Iququzelela i-iyunifomu yombala kwaye iphucule ubukhulu beepatheni eziprintiweyo.

Umzi-mveliso weoyile kunye negesi uqeshiwe kwi-flull fluid njenge-viscosifier kunye nelahleko yelahleko. Inceda ukugcina uzinzo lwe-borehole, inqunyamise i-solidis, kunye nokulawula i-fluid rheelogy ngexesha lokuqhuba.

Ishishini lokwakha: Kwizinto zokwakha ezifana nodaka, i-grgs, kunye neemveliso ze-gypsim, i-CMC isebenza njengearhente yokugcina amanzi, ukuphucula ukusebenza kunye nokunamathela.

Iimveliso zokucoca kunye nokucoca: i-CMC yongezwa kwizitolo, iicoci, kunye neemveliso zokuhlambela njenge-arhente yokuthambisa kunye nokuzinzisa. Iphucula uVekyuli weFomu yoLwandle kwaye iphucule intsebenzo yabo iyonke.

Ukuqwalaselwa kukhuseleko
I-Sodium Carboxymethyl Selelose ithathelwa ingqalelo njengezikhuselekileyo Nangona kunjalo, kubalulekile ukuqinisekisa ukuthotyelwa kwemigangatho yeentsika ezithile kunye namanqanaba okusetyenziswa ukukhusela nayiphi na imiphumo emibi.

Ngelixa i-CMC ithathwa njengetyhefu, ukungasebenzi okugqithisileyo okanye ukufunyanwa kwamasuntswana nothuli kunokubangela ukucaphukisa kwiphecana lokuphefumla kunye ne-gestrointenal. Ukuphatha ngokufanelekileyo kunye nezixhobo zokukhusela (i-PPE) kufuneka ziqeshiwe ngexesha lokuvelisa nokuphatha iinkqubo.

Impembelelo yokusiNgqongileyo
I-CMC isuselwa kwizibonelelo ezihlaziyiweyo, ngokuyintloko isekwe kwiselsulose, isenza i-biodegraded. Ihlambuluka kwe-enzymatic veradations yi-selsesuses, ekugqibeleni ihla iye ezantsi kwikharbon diokside, amanzi kunye ne-biomass.

Nangona kunjalo, inkqubo yemveliso ibandakanya ukuphendula kwekhemikhali kunye namanyathelo amaninzi, enokuba negalelo kwiimpembelelo zokusingqongileyo ezinje njengokusetyenziswa kwamandla, ukukhutshwa kwegesi yeGreenhouse, kunye nokuveliswa kwegesi yemveliso. Iinzame zokuphucula iinkqubo zemveliso, ukonyusa amandla enkunkuma, kwaye ukunciphisa inkunkuma kungayinciphisa ezi zinto zixhalabisa okusingqongileyo.

I-Sodium Carboxymethyl Selelose (CMC) yilaphu eliguquguqukayo ngezicelo ezahlukeneyo, amayeza, amaphepha, iphepha kunye namanye amashishini. Ipropathi yayo eyahlukileyo njenge-polymer ye-solymer yamanzi yenza ukuba ingabaluleki kwimisebenzi eyahlukeneyo, apho ikhonza njenge-thi chulener, i-stabilizer, i-bindesity modifier.
