Kodi ma carbox carboxymethyldelose akonzedwa bwanji?

Kugwiritsa ntchito maletchire monga rawtose, CMC-na idakonzedwa ndi njira ziwiri. Choyamba ndi njira yolumikizira cellulose. Cellulose yomwe imagwira ndi sodium hydroxide kuti ipange cellulose ya alkali, kenako ma celluuse apakati a clorooceic acid kuti apange CMC-Na, omwe amatchedwa kuti kukwaniritsidwa.

Makina a dongosolo ayenera kukhala alkaline. Njira iyi ndi ya Williamson Ether njira. Njira yochitira ndi ma ecchuphicilic. Dongosolo la dongosolo limakhala lalkaline, ndipo limaphatikizidwa ndi zomwe ena amachita mbali yomwe ili pamaso pa madzi, monga sodium gllcolate, glycolic acid ndi zinthu zina zopangidwa ndi zinthu zina. Chifukwa cha kupezeka kwa zovuta, kugwiritsa ntchito ntchito ya alkali ndi zokondweretsa kudzawonjezeredwa, potero kuchepetsa kuchuluka kwa phindu; Nthawi yomweyo, sodium gllcolate, glycolic acid komanso zosafunikira zamchere zimapangidwa kumbali, zomwe zimapangitsa kuyera ndi kuchepetsedwa kwa malonda. Pofuna kupondereza zomwe zimachitika, ndikofunikira kuti mugwiritse ntchito alkali ndiye kuti amagwiritsa ntchito njira zamadzi, komanso kuwongolera alkali ndi njira yosangalatsa pofuna cholinga chokwanira. Nthawi yomweyo, zofuna za malonda pa ufa ndi kuchuluka kwa zolowa m'malo, ndipo kutentha koyambitsa ndi kutentha kuyenera kuganiziridwa bwino. Kuwongolera ndi zinthu zina, kumawonjezera kuchuluka kwa chiyero, ndipo kumalepheretsa kupezeka kwa mbali zosiyanasiyana.

Malinga ndi media yoyeserera, kupanga kwa mafakitale kwa cmc-na kumatha kugawidwa m'magulu awiri: njira zodzipangira zamadzi ndi njira zosungunulira. Njira yogwiritsira ntchito madzi monga momwe momwe amakopera imatchedwa njira ya madzi, yomwe imagwiritsidwa ntchito kupanga alkaline sing'anga ndi yotsika cmc-na. Njira yogwiritsira ntchito zosungunulira zachilengedwe monga momwe mungagwiritsire ntchito zimatchedwa njira yosungunulira, yomwe ndi yoyenera popanga sing'anga komanso kwambiri cmc-na. Izi zimachitika kawirikawiri zimachitika m'munda, womwe ndi wa njira yodulira ndipo pakadali pano ndi njira yayikulu yopangira CMC-na.

WNjira Yapakatikati:

Njira yopangira madzi ndi njira yoyambirira yopanga mafakitale, yomwe ikuyenera kutengera cellulose ndi embixizare wothandizira pansi pa mikhalidwe yaulere ya alkali ndi madzi. Pa nthawi yopepuka ndi kusinthika, palibe worganic mu dongosolo. Zida za zida za Media Media ndi zophweka, ndizochepa komanso mtengo wotsika. Zovuta ndikusowa kwakukulu kwamadzimadzi, kutentha komwe kumapangidwa ndi kutentha, kumathandizira kuthamanga kwa zochitika mbali, kumabweretsa zolimbitsa thupi. Njira imagwiritsidwa ntchito kukonzekeretsa sing'anga ya CMC-yotsika mtengo, monga zotchinga, othandizira ndi monga.

SNjira:

Njira yosungunulira imatchedwanso njira yosungunulira ya organic, ndipo gawo lake lalikulu ndikuti kuphatikizika ndi kusintha komwe kumachitika mothandizidwa ndi mawonekedwe a organic (anzeru). Malinga ndi kuchuluka kwa osagwiritsa ntchito, amagawidwa kuti andigwiritse ntchito komanso njira yolumala. Njira yothetsera sonventyi ndi yofanana ndi njira ya njira yamadzi, komanso magawo awiri a kupembedza ndikudzikuza, koma momwe momwemonso momwe mawonekedwe awiriwa ndi osiyana. Njira yosinthira imapulumutsa njira yochepetsera alkali, kukanikiza, kuphwanya, kukalamba motero momwe zinthu zonse zimakhalira ndi njira yolumikizira. Choyipa ndikuti kutentha kutentha kumakhala kosavuta, ndipo zofunikira ndi mtengo wake ndizokwera. Zachidziwikire, kupanga zida zosiyanasiyana zida zosiyanasiyana, ndikofunikira kuti muyendetse kutentha kwa dongosolo, kudyetsa nthawi, ndi zina zotere, kotero kuti zinthu zabwino kwambiri ndizotheka.
