Kusamala pokonzekera sodium carboxymethyl cellulose

Sodium carboxymethyl cellulose (CMC-Na mwachidule) ndi chinthu chofunikira chosungunuka ndi polima chosungunuka m'madzi, chomwe chimagwiritsidwa ntchito kwambiri m'mafakitale azakudya, zamankhwala, zodzola, nsalu, kupanga mapepala ndi zomangamanga. Monga thickener, stabilizer ndi emulsifier,

1. Zosankha zopangira ndi kuwongolera khalidwe
Posankha CMC-Na, muyenera kusamala posankha zinthu zoyera kwambiri. Zizindikiro zamtundu wazinthu zimaphatikizapo kuchuluka kwa kusintha, kukhuthala, chiyero ndi pH mtengo. Kuchuluka kwa m'malo kumatanthawuza zomwe zili m'magulu a carboxylmethyl mu molekyulu ya CMC-Na. Nthawi zambiri, kuchuluka kwa m'malo kumakhala kokwera, kusungunuka kwabwinoko. Viscosity imatsimikizira kugwirizana kwa yankho, ndipo kalasi yoyenera ya viscosity iyenera kusankhidwa malinga ndi zofunikira zenizeni za ntchito. Kuphatikiza apo, onetsetsani kuti mankhwalawo alibe fungo, alibe zonyansa, ndipo amakwaniritsa miyezo yoyenera, monga kalasi yazakudya, kalasi yamankhwala, etc.

2. Zofunikira zamtundu wamadzi pokonzekera yankho
Pokonzekera yankho la CMC-Na, mtundu wamadzi omwe amagwiritsidwa ntchito ndi wofunikira kwambiri. Nthawi zambiri pamafunika kugwiritsa ntchito madzi oyera kapena madzi oyeretsedwa kuti apewe kutengera zonyansa m'madzi pa yankho la CMC-Na. Zonyansa monga ma ion zitsulo ndi ayoni a kloridi m'madzi zimatha kuchitapo kanthu ndi CMC-Na, zomwe zimakhudza kukhazikika ndi magwiridwe antchito a yankho.

3. Njira yochotsera ndi masitepe
Kutha kwa CMC-Na ndi njira yapang'onopang'ono, yomwe nthawi zambiri imayenera kuchitika pang'onopang'ono:
Pre-kunyowetsa: Musanawonjezere ufa wa CMC-Na m'madzi, ndi bwino kuti muyambe kunyowetsa ndi ethanol pang'ono, propylene glycol kapena glycerol. Izi zimathandiza kupewa ufa kuti usagwirizane pa nthawi ya kusungunuka ndikupanga njira yosagwirizana.
Kudyetsa pang'onopang'ono: Pang'onopang'ono yonjezerani ufa wa CMC-Na pansi pa zovuta. Yesetsani kupewa kuwonjezera ufa wambiri panthawi imodzi kuti mupewe mapangidwe a zotupa komanso zovuta pakutha.
Kugwedeza kwathunthu: Mukathira ufa, pitirizani kusonkhezera mpaka utasungunuka kwathunthu. Kuthamanga kwachangu sikuyenera kukhala kofulumira kwambiri kuti tipewe kubadwa kwa thovu zambiri komanso kukhudza kuwonekera kwa yankho.
Kuwongolera kutentha: Kutentha panthawi ya kusungunuka kumakhala ndi zotsatira zina pa mlingo wa kusungunuka. Nthawi zambiri, kutentha kwapakati pa 20 ° C ndi 60 ° C ndikoyenera. Kutentha kwambiri kungayambitse kukhuthala kwa yankho kutsika komanso kuwononga kapangidwe ka CMC-Na.

4. Kusungirako ndi kukhazikika kwa yankho
Yankho la CMC-Na lokonzedwa liyenera kusungidwa mu chidebe chosindikizidwa ndikupewa kukhudzana ndi mpweya kuti mupewe kuyamwa kwa chinyezi ndi okosijeni. Panthawi imodzimodziyo, kuwala kwa dzuwa ndi kutentha kwakukulu kuyenera kupewedwa momwe zingathere kuti zisawonongeke. Pakusungidwa kwa nthawi yayitali, yankho likhoza kuwonongeka chifukwa cha kukula kwa tizilombo toyambitsa matenda, kotero mutha kulingalira kuwonjezera zotetezera monga sodium benzoate ndi potaziyamu sorbate pokonzekera.

5. Kugwiritsa ntchito ndi kuchiza yankho
Mukamagwiritsa ntchito yankho la CMC-Na, muyenera kusamala kuti musagwirizane ndi ma acid amphamvu komanso zoyambira zolimba kuti mupewe kusintha kwamankhwala komwe kumakhudza kukhazikika ndi magwiridwe antchito a yankho. Kuphatikiza apo, yankho la CMC-Na limakwiyitsa khungu ndi maso pamlingo wina, chifukwa chake muyenera kuvala zida zoyenera zodzitetezera mukamagwiritsa ntchito, monga magolovesi, magalasi, ndi zina zambiri.

6. Kuteteza chilengedwe ndi kutaya zinyalala
Mukamagwiritsa ntchito CMC-Na, muyenera kusamala zachitetezo cha chilengedwe cha zinyalala. Yankho la zinyalala la CMC-Na liyenera kuyendetsedwa motsatira malamulo oyenera kupewa kuwononga chilengedwe. Zinyalala zimatha kuwongoleredwa ndi biodegradation kapena mankhwala.

Pokonzekera yankho la sodium carboxymethyl cellulose, ndikofunikira kulingalira mosamala ndikugwira ntchito kuchokera kuzinthu zingapo monga kusankha kwazinthu zopangira, njira yosungunulira, malo osungira komanso chithandizo chachitetezo cha chilengedwe. Pokhapokha poyang'anira kuwongolera mwamphamvu kwa ulalo uliwonse komwe yankho lokonzekera lingakhale ndi magwiridwe antchito abwino komanso okhazikika kuti akwaniritse zosowa za magawo osiyanasiyana ogwiritsira ntchito.
