Sodium Carboxymethmethmethmethmethyl cellulose (CMC) ndi yolimba komanso yogwiritsidwa ntchito kwambiri yogwiritsidwa ntchito kwambiri ndi ntchito zambiri zamakampani osiyanasiyana.
Kuyamba kwa Sodium Carboxymethyl cellulose (cmc)
Sodium Carboxymethmethmethmethmethyl cellulose, nthawi zambiri zimafupikitsidwa ngati CMC, ndi zochokera ku cellulose, mmodzi mwa owala kwambiri padziko lapansi. Cellulose, opangidwa kuti abwerere mayunitsi a glucose olumikizidwa ndi β (1 → 4) zomangira za glycosidic, zimapezeka makamaka mu chipinda cha cell azomera, zimapereka chithandizo. Zimakhala zotheka, zosafunikira, komanso zopanda poizoni, zimapangitsa kuti ikhale yowoneka bwino yopanga mafakitale osiyanasiyana.
Kapangidwe ndi katundu
CMC imaswa posinthanitsa ndi cellulose, pomwe ma hydroxyl magulu oyambira a cellulose adasinthidwa ndi magulu a carboxymethyl (-ch2-cooh). Izi zimapatsa madzi kusungunuka kwamadzi ndikusintha zinthu zachilengedwe kuti zizipanga bwino kwambiri cellulose, ndikupangitsa kuti ikhale yoyenera kugwiritsa ntchito mitundu yambiri.
Mlingo wa zolowetsa (DS) amatanthauza kuchuluka kwa magulu a carboxymethyl mu gawo la glucose mu cellulose unyolo ndikupangitsa katundu wa cmc. Makhalidwe apamwamba a DS DS amabwera chifukwa cha kuchuluka kwa madzi ndi mafayilo.
CMC imapezeka ngati ufa woyera mpaka ufa woyera, ndi tinthu tating'onoting'ono timatengera ntchito yake. Ndiwopanda fungo, wopanda pake, komanso wopanda poizoni, ndikupangitsa kuti kugwiritsidwa ntchito pogwiritsa ntchito zakudya ndi mankhwala opangira mankhwala. CMC imakhazikika pansi pazinthu zosiyanasiyana za pH ndikuwonetsa katundu wabwino wopanga mawonekedwe.
Njira Zopangira
Kupanga kwa CMC kumaphatikizapo njira zingapo:
Kukonzekera kwa Cellulose: Cellulose nthawi zambiri imachokera ku prglyp zamkati, mabatire a thonje, kapena ulusi wina wazomera. Cellulose imayeretsedwa ndikusweka m'matumba ang'onoang'ono kuti azikhala ndi chitetezo.
Kutengera kwa Zoyenera: ulusi woyeretsa umathandizidwa ndi sodium hydroxide (Naoh) kuti ayambitse magulu a hydroxyl. Pambuyo pake, monochloroortic asidi (kapena mchere wake wa sodium) amawonjezeredwa ku zomwe sizingasakanizo zoyambitsa ma burboxymethyl m'matumbo a cellulose.
Kusalowerera ndi kusambitsidwa: Pambuyo pakutengera chizolowezi, zotsatira zake sizimalowerera ndale kuti musinthe mu mawonekedwe amchere wa sodium. Nthawi yomweyo cmc idatsukidwa kuti ichotse zodetsa komanso zopangidwa ndi zinthu.
Kuyanika ndi Kuthera: CMC yoyeretsedwa imawuma kuti ichotse chinyezi chambiri komanso chosinthika kuti mukwaniritse kukula kwa tinthu.
Gwiritsani ntchito ndi mapulogalamu
Sodium Carboxymethyl cellulose imapeza ntchito zambiri pamakampani osiyanasiyana:
Makampani ogulitsa zakudya: CMC imagwiritsidwa ntchito ngati thicker, okhazikika, ndi chinyezi chosungiramo zinthu zina zamkaka monga mkaka, zophika, ndi mavalidwe. Imakhala bwino kapangidwe kake, imalepheretsa syneresis, ndikuwonjezera pakamwa pakudya zakudya.
Mankhwala opanga mankhwala: M'makampani opanga mankhwala, CMC imagwiritsidwa ntchito ngati chomangira mu piritsi la piritsi, kusintha kwa mawonedwe pakuyikika, komanso mafuta muzovuta za ophthahalmic. Amawagawa kugawa mankhwala osokoneza bongo komanso kumasulidwa.
Zogulitsa Zaumwini: CMC imaphatikizidwa ndi zinthu zaumwini monga mano, ndi mapangidwe a shamgore ngati wothandizila, emulsifier, ndi wothandizira makanema.
Makampani Apepala: Mwapepala Zimawonjezeranso ngalande ndikuchepetsa fumbi pamapepala.
Makampani opanga malembawo: CMC imagwiritsidwa ntchito posindikiza mawonekedwe ndi makina opangira ngati tricner ndi binder for pasts. Imathandizira mawonekedwe a yunifolomu yofanana ndikuwongolera lakuthwa kwa mitundu yosindikiza.
Makampani a mafuta ndi gasi: CMC imagwiritsidwa ntchito pobowola madzi obowola ngati viscosifier ndi madzi ochepetsa madzi. Zimathandizira kusungitsa bankhu, kuyimitsa mphamvu, ndi rheology yamadzimadzi ikamayendetsa.
Makampani omanga: M'makampani omanga monga matope, okonda, ndi mankhwala a gypsum, masentimita amagwira ntchito ngati wosunga madzi, kukonzanso kugwirira ntchito.
Zoyala ndi zoyeretsa: masentimita amawonjezeredwa ku zopatsirana, zoyeretsa, ndi zochapa zochapira ngati kukula komanso kukhazikika. Zimawonjezera mafayilo amadzimadzi amadzimadzi ndipo amasintha magwiridwe awo onse.
Maganizo a chitetezo
Sodium Carboxymethmethmethmethyl cellulose nthawi zambiri imawonedwa ngati yotetezeka (gras) yogwiritsa ntchito mabungwe a USD Komabe, ndikofunikira kuti mutsimikizire kutsatira miyezo yoyenerera ndi kuchuluka kwa kugwiritsa ntchito zovuta zilizonse.
Pomwe CMC imatengedwa ngati yopanda mphamvu, yochulukirapo kapena kunenepa kwa mafumbi kumatha kuyambitsa kupuma komanso m'mimba thirakiti. Zida zoyendetsedwa bwino komanso zoteteza payekha (PPE) ziyenera kugwiritsidwa ntchito popanga ndi kusamalira njira.
Mphamvu ya chilengedwe
CMC imachokera ku zinthu zokonzanso, makamaka cellulose yonyamula mbewu, ndikupangitsa kuti akhale mogwirizana. Zimakhala zowonongeka ndi ma cell, pamapeto pake zinayamba kuwononga kaboni dayokisaidi, madzi, ndi biomass.
Komabe, kupanga kwa masentimita kwa cmc kumaphatikizapo kusintha kwa mankhwala ndi magetsi ambiri, omwe angapangitse mphamvu zachilengedwe monga mphamvu zowonjezera, mpweya wowonjezera kutentha, komanso mikangano yamadzi. Kuyesetsa Kumayesetsa Kupanga Njira Zakupangira, kwezani mphamvu mphamvu, ndikuchepetsa zinyalala kumatha kuthetsa nkhawa za chilengedwe.
Sodium Carboxymethmethmethmethmethyl cellulose (cmc) ndi njira yosiyanasiyana yokhudza ntchito zosiyanasiyana pazakudya, zolemba, pepala, ndi mafayilo ena. Mphamvu zake zapadera ngati polymer yosungunuka madzi zimapangitsa kuti zikhale zofunikira m'njira zosiyanasiyana, komwe imakhala yopanda tanthauzo, kukhazikika, binder, ndi ufa wosintha.
