Sodium carboxymethyl cellulose

Sodium Carboxymethmethmethmethmethmethyl cellulose (cmc) ndi polymer yomwe imagwiritsidwa ntchito kwambiri m'mafakitale ambiri monga chakudya, mankhwala, zodzola, pepala, pepala lobowola mafuta. Imapezeka ndi kusintha kwa mankhwala kwa cellulose. Makhalidwe ake amapangidwa kuti magulu a hydroxyl mu ma molekyulu a celluulose amasinthidwa ndi magulu a carboxymethyl (-ch2cooh) ndikuphatikizidwa ndi sodium msuzi wa sodium.

1. Kapangidwe ka mankhwala ndi katundu

Njira ya mankhwala a sodium carboxymethmethmethmethmethmethmethmethmethmethmethmethmthyl cellose ndi (C6H7O2 (O) 2ch2coona) n, yemwe ali ndi zotupa zina ndi madzi ena. Kapangidwe kake koyambirira ndi kapangidwe ka mzere wopangidwa ndi mamolekyulu a cololise-gluco. Pambuyo mankhwala, ena kapena magulu onse a hydroxyl pa mamolekyulu a cellulose amasinthidwa ndi magulu a carboxymethl kuti apange mamolekyulu osungunuka. Makamaka, matole azosamwa la sodium carboxylyl cellulose imakhala ndi magulu ambiri a carboxymethyl (-ch2cooh), yomwe imatha kulumikizana ndi mamolekyulu amadzi, ndikupereka mawonekedwe abwino.

CMC ili ndi zinthu zotsatirazi:

Kusungunuka kwamadzi: sodium carboxymethyl cellulose amatha kusungunuka mwachangu m'madzi kuti apange yankho la colloml.

Ma Ukuyenera Kusintha kwa CMC kuwoneka bwino kwambiri, ndipo mafayilo amakhudzana ndi kulemera kwake komanso njira yothetsera mavuto.

Kukhazikika: CMC ili ndi bata yabwino kwa asidi, alkali ndi kutentha kwambiri, koma m'malo a acid acid kapena alkali, kukhazikika kwa cmc kudzachepa.

Kusintha: Posintha ma cell ndi digiri ya cmc, mphamvu yake yakuthupi ndi mankhwala ikhoza kulamuliridwa moyenera.

2. Njira Yokonzekera

Sodium Carboxymethyl cellulose nthawi zambiri imakonzedwa ndi celloluose ndi sodium chloroaceate malo okhala. Malingaliro ake ali motere:

Kudzika kwa Cellulose: Choyamba, cellulose (monga fibern firti) imatsukidwa kuti muchotse zosafunikira.

Alkinazation Chimene: Cellulose yokongola imachitika ndi sodium hydroxide njira yolekanitsa pa cellulose molenuwer kuti apange mchere wa cellulose kuti apange mchere wa cellulose.

Yolowa m'malo: Pansi pa Alkalinine, sodium chlorocetate imawonjezeredwa, ndipo sodium chloroceaceate imagwira ndi magulu a hydroxyyl pa ma mamolekyu osungirako ma cellose omwe ali ndi mabotolo a carboxymethyl.
Kusamba ndi Kuyanika: Pambuyo pa zomwe zochita zimamalizidwa, chinthucho chimatsukidwa ndi madzi kuchotsa zosayera, ndipo pamapeto pake kuyeretsa sodium carboxyl cellose cellose cellose cellose cellose cellose cellose cellose limapezeka.

3. Zolemba

Chifukwa cha madzi ake abwino kuswa, kukula ndi kukhazikika, sodium carboxyl cellulose imagwiritsidwa ntchito kwambiri m'minda yotsatirayi:

Makampani ogulitsa zakudya: monga kukula, okhazikika, emulsifier, odzola, enc. Ntchito Yathunthu

Makampani ogulitsa mankhwala: ngati chomangira, wosuta-wosuta, kuyimitsa wothandizira mankhwala, amagwiritsidwa ntchito m'mapiritsi, makapisozi, mafuta am'mimba ndi mafuta ena. Kuphatikiza apo, CMC imagwiritsidwanso ntchito ngati zojambulajambula zopangira opaleshoni ndi zida zamano.

Makampani opanga zodzikongoletsera: ogwiritsidwa ntchito popanga mafuta odzola, mafuta, shampoos, mano ndi zinthu zina ngati thicker ndi kukhazikika. Itha kusintha mamasukidwe a malonda ndikuwonjezera zomwe ogwiritsa ntchito.

Makampani opanga mapepala: Monga momwe mankhwala othandizira amalembera pepala, cmc amatha kusintha mphamvu, kukana madzi ndi kusindikizidwa kwa pepala ndikuchepetsa fumbi pamtunda.

Kubowola Mafuta: Mafuta amabowola mafuta, cmc amagwiritsidwa ntchito pobowola madzi akumadzi ndikukhazikika pamadzimadzi, amathandizira kuchotsa mabowo mozungulira pobowola.

Makampani ogulitsa: monga utoto wobalalitsa ndi kusindikiza zimawonjezera owonjezera, cmc amatha kusintha mafano ndi mawonekedwe a nsalu.

4. Chitetezo ndi chilengedwe

Sodium Carboxymethyl cellulose nthawi zambiri amadziwika kuti ndi otetezeka, ndipo kugwiritsa ntchito chakudya ndi mankhwala avomerezedwa ndi mitundu yowonjezera ya Codex ndi Maiko ambiri. Sikuti si zowawa kwa thupi la munthu ndipo sizikhala ndi mphamvu kwambiri pamalo achilengedwe, motero amagwiritsidwa ntchito kwambiri.

Komabe, ngakhale CMC yokha ndi yochezeka, njira zake zopangira zingaphatikizepo kugwiritsa ntchito ma regents odzola komanso zovuta zamadzimadzi. Chifukwa chake, ndikofunikira kulabadira njira zotetezera zachilengedwe pakupanga njira kuti muchepetse kuchotsera.

Sodium Carboxymethyl cellulose ndi zinthu zambiri zogwiritsidwa ntchito komanso zodziwika bwino polymer. Kukula kwake, kukhazikika ndi kukhazikika kumapangitsa kuti zikhale zofunika kwa mafakitale ambiri. Kuchokera pachakudya, mankhwala okhala m'makampani, CMC imachita mbali yofunika kwambiri. Ndi kupititsa patsogolo kupititsa patsogolo ukadaulo mtsogolo, gawo la CMC lingawonjezere.
