Sodium Carboxymethmethmethmethmethyl cellulose (cmc) ndi unyolo, ether solble, cylelose yamadzi, cellosec wachilengedwe ndi mankhwala a cyloro. Njira yake yothetsera yolimba imakhala ndi ntchito zamphamvu, mawonekedwe a filimu, ogwiritsira ntchito madzi, oteteza mankhwala, mafilimu, ma primics, makampani opanga mankhwala tsiku lililonse ndi minda ina.

Sodium Carboxymethmethmethmethyl cellulose nthawi zambiri imakhala yolimba, nthawi zina yachitsulo, yoyera kapena yopanda mphamvu, m'madzi kuti ipangitse mawonekedwe a viscous ndi kuwonekera kwambiri. Zosatheka pazithandizo za General Organic, monga ethanol, ether, chloroform ndi benzene, koma kusungunuka molunjika, koma soluforning imayambabe, ndipo mankhwalawa alibe ndi mamasukidwe ena. Yolimba m'malo okhazikika amakhala okhazikika, chifukwa ili ndi madzi ena okonda komanso chinyezi, m'malo owuma, chimasungidwa kwa nthawi yayitali.

Njira zopanga

1. Njira ya madzi

Njira ya malasha ndi njira yoyambirira yopangira mafakitale ya sodium carboxyl cellulose. Munjira iyi, alkali cellulose ndi kukonzekera bwino amatenga yankho la oxygen oxide oxygen oxide oxide, ndipo madzi amagwiritsidwa ntchito ngati momwe amachitira mwadzidzidzi, popanda okhazikika.

2. Njira yosungunulira

Njira yothetsera sonvent ndi njira yothetsera njira yopangira, yomwe ndi yopanga yopanga pamaziko a njira ya madzi kuti isinthe madzi ngati sekondale monga momwe amachitira. Njira yoperekera ma alkirization ndi kumayambiriro kwa alkali cellulose ndi monochloroortic acid mu zosungunulira. Malinga ndi kuchuluka kwa sekondale, imatha kugawidwa m'njira youndana ndi njira yosambira. Kuchuluka kwa zosungunulira zomwe zimagwiritsidwa ntchito mu njira yopukutira ndizokulirapo kuposa njira yowerama, ndipo kuchuluka kwa zosungunulira zomwe zimagwiritsidwa ntchito ndi kuchuluka kwa kuchuluka kwa kuchuluka kwa kuchuluka kwa cellulose. Pamene sodium carboxymethyl cellulose imakonzedwa ndi njira yosambira, yomwe imakhazikika imakhala yolumala kapena kuyimitsidwa mu kachitidwe, kotero njira yosambira imatchedwanso njira yoyimitsidwa.

3. Njira yolumala

Njira yocheperako ndiukadaulo waposachedwa kuti apange sodium carboxymethyl cellulose. Njira yochepetsera siyingangopanga ma celloxyl celboxyyl cellouse, komanso imapanga sodium carboxymethyl cellulose ndi digiri yolowera kwambiri ndi yunifolomu. Kupanga njira yochepetsera kumakhala kosiyanasiyana: zamkati za thonje zomwe zakhala zikutumizidwa mu ufa wokhala ndi ufa wokhala ndi mowa wowonjezereka, ndipo kutentha kosasinthika ndi 20 ℃. Pambuyo pa telkalization, zinthuzo zimaponyedwa ku makina ofukizira ofukula, ndipo isopropyl yoledzeretsa yankho la chlorooceic acid imawonjezeredwa, ndipo kutentha kwa 65 ℃. Malinga ndi zomwe zimagwiritsidwa ntchito ndi zofunikira zina, kuchuluka kwa maulendo, nthawi ya ma alkishilization, kuchuluka kwa wothandizidwa ndi nthawi yosinthira ndi njira zina zitha kusintha.

② Ntchito

1. CMC siyongolira kokha mwamphamvu ndikukula mu chakudya, komanso kukhala ndi kuzizira kopambana komanso kusungunuka, ndipo kumatha kusintha kununkhira kwazomera ndikuwonjezera kwa nthawi yopuma.

2. Mu zotchinga, cmc itha kugwiritsidwa ntchito ngati nthumwi yotsutsa-yotsutsa, makamaka yopanga mafomu a Hadrophobic Antiction, bwino kwambiri kuposa nthiti ya carboxymethyl.

3. Kubowola mafuta kumatha kugwiritsidwa ntchito kuteteza zitsime zam'matontho ngati matope, yosungira madzi, kuchuluka kwa mafuta aliwonse ndi zitsime za 2 ~ 6T.

4. Zogwiritsidwa ntchito mu makampani ojambula monga muunitse othandizira, kusindikiza ndi kupatsa utoto wotsekemera, kusindikiza ndi kumaliza ntchito.

5.

6. Monga nyumba yoyendetsedwa ndikuchotsa calcium tion as sodium kuposa sodium gluonete yogwira mtima kwambiri, monga kusinthana kwa ma cution, kusinthika kwa 1.6ml / g.

7. M'makampani ogwiritsa ntchito makalata ogwiritsira ntchito mapepala, amatha kusintha mphamvu yowuma ndi mphamvu yonyowa ya pepala ndi madzi kukana mafuta, inki limayamwa madzi.

8. Monga hydrosol muzodzola, imagwiritsidwa ntchito ngati wothandizira kukula kwa mano, Mlingo wake pafupifupi 5%.
