Phunzirani pokonzekera sodium carboxymethyl cellulose

Sodium Carboxymethmethmethmethmethmethyl cellulose (CMC) ndi carboxymet yochokera ku cellulose, yomwe imadziwikanso kuti Cellulose chingamu, ndipo ndi chingamu chofunikira kwambiri cha cuonic. Nthawi zambiri CMC nthawi zambiri imakhala yopanga polymer poyipitsidwa mwa kugwiritsa ntchito cellulose ndi caustic alkali ndi monochloroortic acid. Kulemera kwa kuchuluka kwa kuchuluka kwa anthu mamiliyoni ambiri mpaka mamiliyoni angapo.

Kukonzekera kwa CMC

Malinga ndi sing'anga yosiyanasiyana, kupanga mafakitale kwa masentimita a cmc kungagawike m'magulu awiri: njira yodzipangira madzi ndi njira yosinthira. Njira yogwiritsira ntchito madzi monga momwe momwe mumachitiramonso njira yotchedwa njira yonyamula madzi, yomwe imagwiritsidwa ntchito kupanga alkaline sing'anga komanso yotsika masentimita; Njira yogwiritsira ntchito zosungunulira zachilengedwe monga momwe momwe zimachitidwira, zomwe zili njira yosungunulira, yomwe ili yoyenera kupanga kwa sing'anga wa sing'anga. Zonsezi zimachitika mu kanda, zomwe zimakhala za njira yodulira ndipo ndi njira yayikulu yopangira cmc pakalipano.

njira yochokera ku madzi

Njira yonyamula madzi ndi njira yoyambirira yopanga mafakitale, yomwe ikuyenera kutengera cellulose ndi wothandizila mu mkhalidwe waulere wa alkali ndi madzi. Panjira yokwanira komanso yoyesa, palibe worganic mu dongosolo. Zida zamagetsi za njira yopanda madzi ndizosavuta, ndizochepa komanso mtengo wotsika. Zovuta ndikuti pakusowa kwa sing'anga yambiri, ndipo kutentha komwe kumapangidwa ndi kutentha, zomwe zimathandizira kuthamanga kwa zinthu mbali zomwe zimachitika, zomwe zimapangitsa kuti pakhale zopindika. Njirayi imagwiritsidwa ntchito kukonzekera zinthu zapakati ndi zochepa za CMC, monga zotchinga, othandizira olemba, etc.

Njira ya Solvent

Njira yosungunulira imadziwikanso kuti njira yothetsera zinthu. Chinthu chake chachikulu ndikuti kuphatikizika ndi kusintha komwe kumachitika pansi pa mkhalidwe womwe sungunuka kwa organic imagwiritsidwa ntchito ngati momwe amachitira (zopanda pake). Malinga ndi kuchuluka kwa omwe akukuchitirani, imagawidwa kuti ikhale njira yodulira komanso njira yolumala. Njira yothetsera sonventyi ndi yofanana ndi njira ya njira yodzipangira madzi, ndipo imakhalanso ndi magawo awiri a kupembedza ndikudzikuza, koma momwe momwemonso momwe mawonekedwe awiriwa ndi osiyana. Njira yothetsera njira imathetsa njira zomwe zimapangidwa mwanjira yopangidwa ndi madzi, monga kuwuma, kufinya, kupindika, ndi kuzila, zonse zimachitika mu harder. Zovuta ndikuti kutentha kwa kutentha kumakhala kwabwino, kufunikira kwake malo ndi mtengo wake ndikokwera. Zachidziwikire, kupanga zida zosiyanasiyana zida zosiyanasiyana, ndikofunikira kuti muyendetse kutentha kwa dongosolo, kudyetsa nthawi, ndi zina zotere, kotero kuti zinthu zabwino kwambiri ndizotheka. Chapa chake chotsika chikuwonetsedwa pa Chithunzi 2.

Mawonekedwe okonzekera sodium Carboxymethyl cellulose kuzaulimi ndi zinthu

Zopangidwa ndi zopangidwa ndi mbewu zimakhala ndi zopezeka zosiyanasiyana komanso zosavuta, ndipo zimatha kugwiritsidwa ntchito ngati zida zophika pokonzekera cmc. Pakadali pano, zopangira za CMC zimapangidwa makamaka ndi cellulose, kuphatikiza fiber, chomera cham'mawa, chomera chotsika mtengo kwambiri cha ma cmc.

Kaonekedwe

Sodium Carboxymethyl cellulose itha kugwiritsidwa ntchito ngati emulsifier, zomata, zomata, zomwe zimapangidwa ndi mafilimu, zimagwiritsidwa ntchito nthawi zonse. Masiku ano, atakumana ndi lingaliro la lingaliro la mankhwala obiriwira, kafukufuku wakunja paukadaulo wa CMC akungoyang'ana zotsika mtengo komanso zosavuta kupeza zida zomera ndi njira zatsopano zoyeretsera kwa masenti. Popeza dziko lomwe lili ndi zida zapamwamba kwambiri, dziko langa limasinthidwa kwambiri pankhani ya ukadaulo, limakhalanso ndi zovuta zopangira, koma palinso zovuta zopangira magwero osiyanasiyana. Pali zofooka za kugwiritsidwa ntchito kwa kugwiritsa ntchito zida zama biomass, motero kukwaniritsa zina m'malo awa kumafunikira kuchitika kafukufuku wamkulu
