1. Chidule Chachidule cha Carboxymethyl Cellulose
Dzina la Chingerezi: Carboxyl methyl Cellulose
Chidule cha CMC
Mapangidwe a mamolekyu ndi osiyanasiyana: [C6H7O2(OH)2CH2COONA]n
Maonekedwe: woyera kapena kuwala wachikasu fibrous granular ufa.
Kusungunuka kwamadzi: kusungunuka mosavuta m'madzi, kupanga mawonekedwe owoneka bwino a viscous colloid, ndipo yankho lake sililowerera ndale kapena lamchere pang'ono.
Mawonekedwe: Mamolekyu apamwamba kwambiri amtundu wa colloid, osanunkhiza, osakoma komanso opanda poizoni.
Ma cellulose achilengedwe amagawidwa kwambiri m'chilengedwe ndipo ndi polysaccharide yochuluka kwambiri. Koma popanga, cellulose nthawi zambiri imakhala ngati sodium carboxymethyl cellulose, motero dzina lonse liyenera kukhala sodium carboxymethyl cellulose, kapena CMC-Na. Amagwiritsidwa ntchito kwambiri m'makampani, zomangamanga, zamankhwala, chakudya, nsalu, zoumba ndi zina.
2. Carboxymethyl cellulose luso
Ukadaulo wosintha wa cellulose umaphatikizapo: etherification ndi esterification.
Kusintha kwa carboxymethyl cellulose: carboxymethylation reaction muukadaulo wa etherification, cellulose ndi carboxymethylated kuti ipeze carboxymethyl cellulose, yotchedwa CMC.
Ntchito ya carboxymethyl cellulose amadzimadzi solution: thickening, filimu kupanga, kugwirizana, kusunga madzi, colloid chitetezo, emulsification ndi kuyimitsidwa.
3. Chemical reaction ya carboxymethyl cellulose
Ma cellulose alkalization reaction:
[C6H7O2(OH) 3]n + nNaOH→[C6H7O2(OH) 2ONa ]n + nH2O
Etherification reaction ya monochloroacetic acid pambuyo pa alkali cellulose:
[C6H7O2(OH) 2ONa ]n + nClCH2COONA →[C6H7O2(OH) 2OCH2COONA ]n + nNaC
Chifukwa chake: njira yopangira carboxymethyl cellulose ndi: Cell-O-CH2-COONA NaCMC
Sodium carboxymethyl cellulose(NaCMC kapena CMC mwachidule) ndi madzi sungunuka cellulose efa kuti akhoza kuchititsa mamasukidwe akayendedwe ambiri ntchito madzi amadzimadzi formulations amasiyana ma cP angapo zikwi zingapo cP.
4. Makhalidwe a mankhwala a carboxymethyl cellulose
1. Kusungirako kwa madzi amadzimadzi a CMC: Ndiwokhazikika pansi pa kutentha kochepa kapena kuwala kwa dzuwa, koma acidity ndi alkalinity ya yankho idzasintha chifukwa cha kusintha kwa kutentha. Mothandizidwa ndi kuwala kwa ultraviolet kapena tizilombo tating'onoting'ono, kukhuthala kwa yankho kumachepa kapena kuipitsidwa. Ngati kusungidwa kwa nthawi yayitali kumafunika, chosungira choyenera chiyenera kuwonjezeredwa.
2. Kukonzekera njira ya CMC amadzimadzi njira: kupanga particles uniformly chonyowa choyamba, amene akhoza kwambiri kuonjezera mlingo kuvunda.
3. CMC ndi hygroscopic ndipo iyenera kutetezedwa ku chinyezi panthawi yosungira.
4. Mchere wachitsulo wolemera monga nthaka, mkuwa, lead, aluminiyamu, siliva, chitsulo, malata, ndi chromium ungayambitse CMC kugwa.
5. Mvula imapezeka mu njira yamadzi yomwe ili pansi pa PH2.5, yomwe imatha kubwezeretsedwanso pambuyo pa neutralization powonjezera alkali.
6. Ngakhale kuti mchere monga calcium, magnesium ndi mchere wa tebulo alibe mphamvu yamvula pa CMC, amachepetsa kukhuthala kwa yankho.
7. CMC n'zogwirizana ndi zomatira madzi sungunuka, softeners ndi resins.
8. Chifukwa cha kusakaniza kosiyana, maonekedwe a CMC akhoza kukhala ufa wabwino, tirigu wonyezimira kapena fibrous, zomwe ziribe kanthu kochita ndi thupi ndi mankhwala.
9. Njira yogwiritsira ntchito ufa wa CMC ndi yosavuta. Ikhoza kuwonjezeredwa mwachindunji ndikusungunuka m'madzi ozizira kapena madzi ofunda pa 40-50 ° C.
5. Digiri ya m'malo ndi kusungunuka kwa carboxymethyl cellulose
Mlingo wolowa m'malo umatanthawuza kuchuluka kwamagulu a sodium carboxymethyl omwe amaphatikizidwa pagawo lililonse la cellulose; mtengo wokwanira wa digiri yoloweza m'malo ndi 3, koma yothandiza kwambiri m'mafakitale ndi NaCMC yokhala ndi digiri yakusintha kuchokera ku 0.5 mpaka 1.2. Katundu wa NaCMC wokhala ndi digiri ya 0.2-0.3 ndi yosiyana kwambiri ndi ya NaCMC yokhala ndi digiri ya 0.7-0.8. Yoyamba imasungunuka pang'ono mu pH 7 madzi, koma yotsirizirayi ndi yosungunuka kwathunthu. Chosiyana ndi chowona pansi pamikhalidwe yamchere.
6. Digiri ya polymerization ndi viscosity ya carboxymethyl cellulose
Digiri ya polymerization: imatanthawuza kutalika kwa unyolo wa cellulose, womwe umatsimikizira kukhuthala. Kutalikirapo kwa unyolo wa cellulose, kukhathamira kwakukulu, komanso yankho la NaCMC.
Viscosity: Njira ya NaCMC ndi madzi osakhala a Newtonian, ndipo kukhuthala kwake kumachepa pamene mphamvu yometa ubweya ikuwonjezeka. Kugwedeza kutayimitsidwa, mamasukidwe akayendedwe adakula molingana mpaka adakhazikika. Ndiko kuti, yankho ndi thixotropic.
7. Ntchito zosiyanasiyana za carboxymethyl cellulose
1. Makampani omanga ndi ceramic
(1) zokutira Zomangamanga: kubalalitsidwa bwino, kugawa yunifolomu ❖ kuyanika; palibe layering, kukhazikika kwabwino; zabwino thickening kwenikweni, chosinthika ❖ kuyanika mamasukidwe akayendedwe.
(2) Makampani a ceramic: amagwiritsidwa ntchito ngati chomangira chopanda kanthu kuti apititse patsogolo pulasitiki ya dongo; glaze chokhazikika.
2. Mafakitale ochapira, zodzoladzola, fodya, zosindikizira nsalu ndi zopaka utoto
(1) Kutsuka: CMC imawonjezedwa ku chotsukira kuti dothi lotsuka lisalowenso pansalu.
(2) Zodzoladzola: thickening, dispersing, suspending, stabilizing, etc. Ndizopindulitsa kupereka masewera athunthu kuzinthu zosiyanasiyana zodzoladzola.
(3) Fodya: CMC imagwiritsidwa ntchito polumikiza mapepala a fodya, omwe amatha kugwiritsa ntchito bwino tchipisi ndikuchepetsa kuchuluka kwa masamba afodya aiwisi.
(4) Zovala: Monga chomaliza cha nsalu, CMC imatha kuchepetsa kudumpha kwa ulusi ndikutha kusweka pa looms yothamanga kwambiri.
(5) Kusindikiza ndi Kudaya: Amagwiritsidwa ntchito posindikiza phala, zomwe zimatha kupititsa patsogolo mphamvu ya hydrophilic ndi kulowa mkati mwa utoto, kupanga utoto yunifolomu ndikuchepetsa kusiyana kwa mitundu.
3. Udzudzu koyilo ndi kuwotcherera ndodo makampani
(1) Kuzingirira kwa udzudzu: CMC imagwiritsidwa ntchito pozingirira udzudzu kuti udzudzu ukhale wolimba komanso kuti usathyoke ndi kusweka.
(2) Electrode: CMC imagwiritsidwa ntchito ngati glaze kuti ipangitse zokutira za ceramic kukhala zomangika bwino komanso kupangidwa, ndikuchita bwino pakutsuka, komanso zimakhala ndi magwiridwe antchito pakutentha kwambiri.
4. Makampani otsukira mano
(1) CMC ali ngakhale bwino ndi zipangizo zosiyanasiyana zopangira mankhwala otsukira mano;
(2) Phalalo ndi losakhwima, sililekanitsa madzi, silisenda, silikhuthala, lili ndi thovu lochuluka;
(3) Kukhazikika kwabwino komanso kusasinthika koyenera, komwe kungapereke mankhwala otsukira mano mawonekedwe abwino, kusungidwa komanso kukoma kosangalatsa;
(4) Kusagwirizana ndi kusintha kwa kutentha, kunyowa ndi kukonza fungo.
(5) Kumeta ubweya waung’ono ndi misala m’zitini.
5. Makampani opanga zakudya
(1) Acidic zakumwa: Monga stabilizer, mwachitsanzo, kuteteza mpweya ndi stratification wa mapuloteni mu yogurt chifukwa aggregation; kukoma bwino pambuyo Kutha mu madzi; kusintha kwabwino kofanana.
(2) Ayisikilimu: Pangani madzi, mafuta, mapuloteni, ndi zina zotero.
(3) Mkate ndi makeke: CMC imatha kuwongolera kukhuthala kwa batter, kupititsa patsogolo kusungirako chinyezi komanso moyo wa alumali wazinthu.
(4) Zakudyazi: onjezerani kulimba ndi kukana kuphika kwa Zakudyazi; imakhala ndi mawonekedwe abwino mu masikono ndi zikondamoyo, ndipo pamwamba pa keke ndi yosalala komanso yosavuta kuswa.
(5) Phala wapomwepo: ngati nkhokwe.
(6) CMC ndi physiologically inert ndipo ilibe phindu la calorific. Choncho, zakudya zochepa zama calorie zimatha kupangidwa.
6. Makampani opanga mapepala
CMC imagwiritsidwa ntchito popanga mapepala, zomwe zimapangitsa kuti pepala likhale ndi kachulukidwe kwambiri, kukana kulowa kwa inki, kusonkhanitsa sera komanso kusalala. Popanga utoto wa pepala, zimathandizira kuwongolera kusinthasintha kwa phala lamtundu; Zitha kupititsa patsogolo kusamata pakati pa ulusi mkati mwa pepala, potero kumapangitsa kuti pepala likhale lolimba komanso lolimba.
7. Makampani amafuta
CMC imagwiritsidwa ntchito pobowola mafuta ndi gasi, kukumba bwino ndi ntchito zina.
8. Zina
Zomatira za nsapato, zipewa, mapensulo, ndi zina zotero, zopukutira ndi zopaka utoto zachikopa, zowongolera zozimitsa moto za thovu, ndi zina zambiri.
