Carboxymethyl cellulose (CMC)

Kufotokozera mwachidule:

Pakadali pano, ukadaulo wosinthika wa cellulose umayang'ana kwambiri etherification ndi esterification.Carboxymethylation ndi mtundu waukadaulo wa etherification.Carboxymethyl mapadi (CMC) analandira ndi carboxymethylation wa mapadi, ndi yankho amadzimadzi ali ndi ntchito za thickening, filimu mapangidwe, kugwirizana, kusunga chinyezi, chitetezo colloidal, emulsification ndi kuyimitsidwa, ndipo chimagwiritsidwa ntchito kutsuka, mafuta, chakudya, mankhwala, nsalu ndi mapepala ndi mafakitale ena.Ndi imodzi mwama cellulose ethers ofunika kwambiri.

Amapangidwa kuchokera ku cellulose zotumphukira za carboxymethyl, zomwe zimathandizidwa ndi sodium hydroxide kupanga alkali cellulose, kenako amachita ndi monochloroacetic acid.Glucose yomwe imapanga cellulose imakhala ndi magulu atatu osinthika a hydroxyl, kotero kuti zinthu zomwe zimakhala ndi magawo osiyanasiyana zimatha kupezeka.Pamene 1mmol carboxymethyl imayambitsidwa pa 1g yowuma kulemera pafupifupi, imakhala yosasungunuka m'madzi ndi kusungunula asidi, koma imatha kutupa ndi kugwiritsidwa ntchito pa chromatography ya ion.Carboxymethyl pKa, pafupifupi 4 m'madzi oyera ndi 3.5 mu 0.5mol / L NaCl, ndi ofooka acidic cation exchanger, kawirikawiri amagwiritsidwa ntchito kulekanitsa ndale ndi zofunika mapuloteni pH> 4. Pamene oposa 40% hydroxyl gulu ndi carboxymethyl, izo akhoza kupasuka m'madzi kupanga khola colloidal njira ndi mkulu mamasukidwe akayendedwe.

Kugwiritsa Ntchito Mankhwala

Carboxymethyl cellulose (CMC) ndi ufa wopanda poizoni komanso wopanda kukoma woyera wokhala ndi magwiridwe antchito okhazikika komanso osavuta kusungunuka m'madzi.Yake amadzimadzi njira ndi ndale kapena zamchere mandala viscous madzi, sungunuka m'madzi sungunuka zomatira ndi utomoni, ndi insoluble mu organic solvents monga Mowa.CMC angagwiritsidwe ntchito ngati binder, thickener, kuyimitsidwa wothandizira, emulsifier, dispersant, stabilizer, sizing wothandizira, etc. Carboxymethyl mapadi (CMC) ndi zokolola lalikulu la mapadi efa, ambiri ankagwiritsa ntchito, kwambiri yabwino mankhwala, amene amadziwika kuti ". mafakitale MSG".

Detergency

1. Sodium carboxymethyl cellulose ndi surfactant, yomwe ingagwiritsidwe ntchito ngati anti-fouling re-deposition, yomwe ndi dispersant ndi surfactant ya madontho particles, kupanga zomangira adsorption wosanjikiza pa banga kuti aletse ake adsorption kachiwiri pa CHIKWANGWANI. .

2. Pamene sodium carboxymethyl cellulose ikuwonjezeredwa ku ufa wochapira, yankho likhoza kufalikira mofanana ndi kutengeka mosavuta pamwamba pa tinthu tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono ta hydrophilic adsorption kuzungulira tinthu tolimba.Ndiye pamwamba mavuto pakati pa madzi ndi olimba particles ndi zosakwana padziko mavuto mkati olimba particles, ndi kunyowa zotsatira za surfactant molekyulu kuwononga mgwirizano pakati olimba particles.Izi zimamwaza dothi m'madzi.

3. Sodium carboxymethyl cellulose imawonjezeredwa ku ufa wochapira, womwe uli ndi emulsifying effect.Pambuyo emulsifying mafuta sikelo, si kophweka kusonkhanitsa ndi precipitate pa zovala.

4. Sodium carboxymethyl cellulose imawonjezeredwa ku ufa wochapira, womwe umakhala ndi mphamvu yonyowetsa ndipo ukhoza kulowa mu tinthu tating'onoting'ono ta hydrophobic, kuphwanya tinthu tating'onoting'ono mu colloidal particles, kuti dothi likhale losavuta kuchoka mu fiber.

Kuwonjezera chakudya

CMC chimagwiritsidwa ntchito mu makampani chakudya, mu zosiyanasiyana zakumwa mkaka, zokometsera, amasewera mbali ya thickening, kukhazikika ndi kuwongolera kukoma, mu ayisikilimu, mkate ndi phala, Zakudyazi nthawi yomweyo ndi phala ndi zakudya zina, amatenga mbali. kupanga, kukonza kukoma, kusunga madzi, kukulitsa kulimba ndi zina zotero.Pakati pawo, FH9, FVH9, FM9 ndi FL9 ali ndi kukhazikika kwa asidi wabwino.Zogulitsa zowonjezera zamtundu wapamwamba zimakhala ndi zinthu zabwino zokhuthala.CMC imatha kuthetsa vuto la kulekanitsa kwamadzi olimba ndi mpweya wa chakumwa cha lactic acid pamene mapuloteni ndi aakulu kuposa 1%, ndipo akhoza kupanga mkaka wa lactic acid kukhala wabwino.The opangidwa mkaka lactic akhoza kukhala bata mu PH osiyanasiyana 3.8-4.2, akhoza kupirira pasteurization ndi 135 ℃ yomweyo njira yolera yotseketsa, mankhwala khalidwe khola ndi odalirika, ndipo akhoza kusungidwa pa kutentha wabwinobwino kwa miyezi isanu ndi umodzi.Zakudya zoyambira zopatsa thanzi komanso kukoma kwa yogurt sizisintha.Ayisikilimu ndi CMC, angalepheretse kukula kwa ayezi makhiristo, kotero kuti ayisikilimu kukoma makamaka yosalala pamene kudya, palibe zomata, zonona, mafuta olemera ndi kukoma zina zoipa.Komanso, kuchuluka kwa kutupa ndikwambiri, ndipo kukana kutentha ndi kusungunuka kusungunuka ndizabwino.CMC ya Zakudyazi pompopompo imapangitsa Zakudyazi kukhala zolimba bwino, kukoma kwabwino, mawonekedwe athunthu, kutsika kwa supu, komanso kumachepetsanso mafuta (pafupifupi 20% kutsika kuposa mafuta oyambira).

Mkulu chiyero mtundu

Paper grade CMC imagwiritsidwa ntchito popanga mapepala, kuti pepala likhale ndi kachulukidwe kake, kutsekemera kwa inki yabwino, kumathandizira kumamatira pakati pa ulusi mkati mwa pepala, potero kuwongolera pepala ndi kukana kupindika.Limbikitsani kumamatira kwamkati kwa pepala, kuchepetsa fumbi losindikiza panthawi yosindikiza, kapena ngakhale fumbi lopanda.Pamwamba pamapepala kuti mupeze kusindikiza bwino komanso kukana mafuta kuti musindikize bwino.Pamwamba pa pepala kumapangitsa kuwala, kumachepetsa porosity, ndipo kumagwira ntchito yosungira madzi.Zimathandiza kufalitsa pigment, kutalikitsa moyo wa scraper, ndikupereka madzi abwino, mawonekedwe owoneka bwino komanso kusindikiza kusinthasintha kwa mapangidwe apamwamba olimba.

Gulu lotsukira mkamwa

CMC ili ndi pseudoplasticity yabwino, thixotropy ndi pambuyo pake.Phala la mankhwala otsukira mano ndi lokhazikika, kusasinthasintha kuli koyenera, mawonekedwe ake ndi abwino, mankhwala otsukira m'mano samathirira, samasenda, samasweka, phala ndi lowala komanso losalala, losakhwima, komanso losagwirizana ndi kusintha kwa kutentha.Kugwirizana kwabwino ndi zida zosiyanasiyana zotsukira mano;Itha kugwira ntchito yabwino pakuumba, kulumikiza, kunyowetsa ndi kukonza kununkhira.

Zapadera za ceramics

Popanga ceramic, amagwiritsidwa ntchito motsatana mu ceramic embryo, glaze phala ndi glaze yamaluwa.Ceramic grade CMC imagwiritsidwa ntchito ngati binder yopanda kanthu mu ceramic billet kupititsa patsogolo mphamvu ndi pulasitiki ya billet.Limbikitsani zokolola.Mu ceramic glaze, imatha kuletsa kugwa kwa tinthu ting'onoting'ono ta glaze, kupititsa patsogolo luso la kumamatira kwa glaze, kukonza kulumikizana kwa glaze komwe kulibe kanthu komanso kulimbitsa mphamvu ya glaze.Ili ndi permeability yabwino ndi kubalalitsidwa mu glaze yosindikizira, kuti glaze yosindikiza ikhale yokhazikika komanso yofanana.

Malo opangira mafuta apadera

Iwo ali ndi makhalidwe a yunifolomu m'malo mamolekyu, mkulu chiyero ndi otsika mlingo, amene angathe kusintha dzuwa la ndondomeko matope.Kukana kwabwino kwa chinyezi, kukana mchere ndi kukana kwa alkaline, koyenera kusakaniza ndi kugwiritsa ntchito madzi amchere odzaza ndi madzi a m'nyanja.Ndizoyenera kukonzekera ufa komanso nthawi yayitali yokhuthala m'munda wogwiritsa ntchito mafuta.Polyanionic cellulose (PAC-HV) ndi viscosifier yogwira mtima kwambiri yokhala ndi zokolola zambiri komanso kuthekera kochepetsera kutaya madzi m'matope.Polyanionic cellulose (PAC-LV) ndi yabwino kwambiri yochepetsera kutayika kwamadzi mumatope, yomwe imayendetsa bwino kwambiri kutaya madzi m'matope amadzi am'nyanja ndi matope amchere amchere.Oyenera dongosolo matope ndi zovuta kulamulira olimba ndi osiyanasiyana kusintha.CMC, monga gel fracturing madzimadzi, ali makhalidwe a gelatinability wabwino, wamphamvu mchenga kunyamula mphamvu, mphira kusweka mphamvu ndi otsika zotsalira.
