CarboxyMethyl Cellulose (CMC) inowanikwa mushure mekutakura carboxymethylation ye cellulose. Mhinduro yayo yemvura ine mabasa ekuremerwa, kuumbwa-kuumba, kudzivirirwa kwemvura, uye kune mapepa ekuparadzaniswa, ethescalsecari Iyo yazvino yekugadziridzwa tekinoroji yemasero inonyanya kutarisa kujekesa uye nekukasira. CarboxyMethylation rudzi rwechinzvimbo chekuchinja.
Zvivakwa zvemuviri
Sodium CarboxyMethyl Cellerose (CMC) ndeye anonic cellolose ether, ine chena kana kuti yakachena flecucleent fiber purodhara, isina mafuta nyore nyore midziyo yemvura inotonhora kana mvura inopisa, kugadzira imwe viscosity yakajeka mhinduro. Mhinduro yacho isina kwayakarerekera kana zvishoma alkalin Iyo hygroscopic, yakagadzikana pakujeka uye kupisa, iyo viscosity inodzikira pakuwedzera kwekudziya, iyo yekudziya yakaderera pane iyo 252
zvemakemikari zvivakwa
Iyo yakagadzirirwa kubva kuCellulose Detivatives yeCarboxymethyl Substitues, Kurapa Cellumlose Sodium Hydroxide kuumba Alkali Cellerocose, uye wozoita ne monuchloroacetic acid. Iyo glucose unit iyo inoda cellulose ine 3 hydroxyl mapoka ayo anogona kutsiviwa, saka zvigadzirwa zvine madhigirii akasiyana anogona kuwanikwa. Paavhareji, 1 mmol ye carboxymethyl yakaunzwa pa 1 g yehuremu hwakaoma, iyo isingaoneki mumvura uye yakafukidzwa acid, asi inogona kushandurwa uye inoshandiswa ion exchangegraphy. CarboxyMethyl PKA inenge 4 mumvura yakachena uye anenge 0.5mol / l nacl. Iyo isina kusimba acidic cation exchanger uye inowanzoshandiswa pakuparadzaniswa kweasina kwaakarerekera uye mapuroteni ekutanga kuPH> 4. Vanopfuura makumi mana muzana emapoka eiyo hydroxyl vanotsiviwa neCarboxyMeymethyl mapoka mapoka, ayo anogona kunyungudutswa mumvura kuti aumbe yakagadzikana yakakwira-viscosity solution.
Chinangwa chikuru
CarboxyMethyl Cellelose (CMC) isisiri-ine chepfu uye isina kuchena chena flucculent poda nehuremu hwakagadzikana uye unyoro mumvura. Mhinduro yaro yemvura ndeyekusarerekera kana alkaline yakajeka viscous mvura, svutugadzike mune imwe gluxo-soluble glues uye inovhara, uye isinganyanye. mune organic soles yakadai se ethanol. Cmc inogona kushandiswa sekunamatira, thickener, kumisa mumiririri, emulsifieri, kuparadzira, stabilizer, sigy mumiririri, nezvimwe.
Sodium carboxymethyl cellose
1. Iyo inoshandiswa kune mafuta uye yakasikwa gasi dhiraivha, kunyatsochera uye mamwe mapurojekiti
① matope ane cmc inogona kuita kuti rusvingo ratsime gadzira chingwa chakaonda uye chakasimba cheki neyekupedzisira kuderera, izvo zvinoderedza kurasikirwa kwemvura.
Pashure pokuwedzera cmc kumatope, iyo yekuchera rig inogona kuwana yakaderera shear Simba reShear, kuitira kuti iwo matope anogona nyore nyore kusunungura gasi rakarukwa mariri, uye panguva imwe chete, marara anokurumidza kuraswa mugomba rematope.
③drilling matope, semamwe kuparadzaniswa kwemamwe, ane imwe nguva yekuvapo, uye kuwedzera kweCMC kunogona kuita kuti ive yakagadzikana uye inowedzera nguva yekuvapo.
④ Madhaka ane cmc haawanzo kukanganiswa nekuumbwa, saka hazvidikanwe kuchengetedza yakakwira pH kukosha uye shandisa zvinodzivirira.
⑤ Ine cmc sekukweva kwematope yekugeza fluid kurapa mumiririri, iyo inogona kuramba kusvibiswa kwemakumbo akasiyana siyana ekunyaradza.
⑥ matope ane cmc ane kugadzikana kwakanaka uye kunogona kuderedza kurasikirwa kwemvura kunyangwe kana tembiricha iri pamusoro pe150 ℃.
CMC neKudenga kweVanhukombe uye yakakwirira mwero wekutsiva yakakodzera matope ane yakaderera density, uye cmc neyekudzika viscosity uye yakakwirira viscosity uye yakakwirira mwero wekutsiva yakakodzera matope ane yakakura. Iko kusarudzwa kweCMC kunofanirwa kutsanangurwa zvinoenderana nemamiriro ezvinhu akasiyana senge madhiri, dunhu uye kudzika kwakadzika.
2. Inoshandiswa muzvinyorwa, kudhinda uye indasitiri yekudyira. Iyo indasitiri yemiindaniso inoshandisa cmc seyekuita mumiririri wechiedza yerudzi rwechiedza chekotoni, silika makushe, makemikari fiber, zvimwe zvinosanganiswa;
3. Inoshandiswa mune yepepa indasitiri CMC inogona kushandiswa sepepa pamusoro pemumiriri uye kuronga mumiririri muenhau yepepa. Kuwedzera 0,1% kusvika 0.3% cmc kune iyo pulp inogona kusimudzira simba repepa ne40% kusvika 50%, uye kuwedzera knodelability ne4 kusvika ku5 nguva.
4 Makemikari ezuva nezuva akadai seanokutora Indasitiri CMC Glycerin Soluce Solution inoshandiswa segamandi remberi. Indasitiri yechechi inoshandiswa seyekadzi uye emulsifier; CMC Makwikwi Mvura yakakwenenzverwa uye inoshandiswa kuyerera mineral kugadzirisa, nezvimwe.
5. Muindasitiri yeCeramic, inogona kushandiswa seinonamatira, plasticzez, kumisa mumiririri weGlaze, ruvara kugadzirira mumiririri, nezvimwe.
6. Inoshandiswa mukuvaka kuti uvandudze kuchengetwa kwemvura uye simba
7. Inoshandiswa muindasitiri yechikafu. Indasitiri yekudya inoshandisa cmc ine subtution degree seyakakwenenzverwa nekuda kwechando
8. Iyo indasitiri yemishonga inosarudza cmc ine yakakodzera viscosity sechipatara binder, kupaza, uye kumhanyisa mumiririri wekumiswa.
