Kukhuthala kwakukuluCMCndi zoyera kapena zamkaka zoyera za ulusi kapena ma granules, zonenepa 0.5-0.7 g/cm3, pafupifupi zopanda fungo, zosakoma, ndi hygroscopic. Mosavuta omwazikana m'madzi kupanga mandala colloidal njira, insoluble mu organic solvents monga Mowa. PH ya 1% yothetsera madzi ndi 6.5 mpaka 8.5. Pamene pH ndi> 10 kapena <5, kukhuthala kwa guluu kudzachepetsedwa kwambiri, ndipo ntchitoyo idzakhala yabwino kwambiri pamene pH ili 7. Mlingo wa CMC m'malo mwake umakhudza mwachindunji kusungunuka, emulsification, ndi kupititsa patsogolo kwa CMC. Kusasinthika, kukhazikika, kukana kwa asidi ndi kukana mchere ndi zinthu zina.
Ambiri amakhulupirira kuti pamene mlingo wolowa m'malo uli pafupi ndi 0.6-0.7, ntchito ya emulsifying imakhala yabwinoko, ndipo ndi kuwonjezeka kwa mlingo wolowa m'malo, katundu wina amasinthidwa moyenerera. Pamene mlingo wolowa m'malo uli waukulu kuposa 0,8, kukana kwake kwa asidi ndi kukana mchere kumawonjezeka kwambiri. .
Zizindikiro zazikulu zoyezera mtundu wa CMC ndi digiri ya m'malo (DS) ndi chiyero. Nthawi zambiri, katundu wa CMC ndi wosiyana ngati DS ndi yosiyana; kumtunda kwa mlingo woloweza m'malo, kumapangitsanso kusungunuka kwamphamvu, komanso bwino kuwonekera ndi kukhazikika kwa yankho. Malinga ndi malipoti, kuwonekera kwa CMC ndikwabwinoko pomwe kuchuluka kwa m'malo ndi 0.7-1.2, ndipo kukhuthala kwake kwamadzimadzi ndikokulirapo pomwe pH mtengo ndi 6-9.
Ubwino wa CMC zomalizidwa makamaka zimatengera yankho la mankhwalawo. Ngati yankho la mankhwalawa likuwonekera bwino, pali tinthu tating'ono ta gel, ulusi waulere, ndi mawanga akuda a zonyansa, zimatsimikiziridwa kuti mtundu wa CMC ndi wabwino. Ngati yankho latsala kwa masiku angapo, yankho silikuwoneka. White kapena turbid, koma zomveka bwino, ndicho chinthu chabwino!
1. Chidule chachidule cha kalasi yapamwamba yamakayendedwe aukadaulo a CMC ndi kalasi yaukadaulo yaukadaulo ya CMC yamafuta obowola mafuta
1. Matope a CMC amatha kupanga khoma lachitsime kukhala keke yopyapyala komanso yolimba yokhala ndi permeability yochepa, kuchepetsa kutaya kwa madzi.
2. Pambuyo powonjezera CMC kumatope, chobowola chobowola chikhoza kupeza mphamvu yochepa yoyamba yometa ubweya, kotero kuti matope amatha kumasula mpweya wokulungidwa mmenemo, ndipo panthawi imodzimodziyo, zinyalala zimatha kutayidwa mwamsanga mu dzenje lamatope.
3. Kubowola matope, monga kuyimitsidwa kwina ndi kubalalitsidwa, kumakhala ndi nthawi yayitali. Kuwonjezera CMC kumatha kupangitsa kuti ikhale yokhazikika ndikutalikitsa moyo wa alumali.
4. Matope omwe ali ndi CMC samakhudzidwa kawirikawiri ndi nkhungu, choncho sikoyenera kukhala ndi pH yamtengo wapatali ndikugwiritsa ntchito zotetezera.
5. Muli CMC ngati wothandizira pobowola matope kukhetsa madzimadzi, amene akhoza kukana kuipitsa zosiyanasiyana sungunuka mchere.
6. Matope okhala ndi CMC amakhala okhazikika bwino ndipo amatha kuchepetsa kutayika kwa madzi ngakhale kutentha kuli pamwamba pa 150 ° C.
Ndemanga: CMC ndi mamasukidwe akayendedwe mkulu ndi digiri mkulu m'malo ndi oyenera matope ndi otsika kachulukidwe, ndi CMC ndi otsika mamasukidwe akayendedwe ndi mkulu digiri ya m'malo ndi oyenera matope ndi kachulukidwe mkulu. Kusankhidwa kwa CMC kuyenera kutsimikiziridwa malinga ndi mikhalidwe yosiyanasiyana monga mtundu wamatope, dera, ndi kuya kwachitsime.
Main ntchito: MB-CMC3 imagwira ntchito yokweza ndi kutsitsa kutaya madzi ndi kukhuthala kwa mamasukidwe akayendedwe pobowola madzimadzi, cementing madzimadzi ndi fracturing madzimadzi, kuti akwaniritse ntchito zoteteza khoma, kunyamula cuttings, kuteteza kubowola pang'ono, kuteteza matope kutayika ndi kuwonjezeka. liwiro pobowola. Onjezerani mwachindunji kapena mupange guluu ndikuwonjezera pamatope, onjezerani 0.1-0.3% ku slurry yamadzi atsopano, ndikuwonjezera 0.5-0.8% ku slurry yamadzi amchere.
2. Kugwiritsa ntchito CMC pamakampani opanga zokutira
Cholinga chachikulu:
Monga stabilizer, imatha kuletsa zokutira kuti zisalekanitse chifukwa cha kusintha kwakukulu kwa kutentha.
Monga tackifier, imatha kupanga mawonekedwe a yunifolomu yokutira, kukwaniritsa malo abwino osungirako ndikumanga mamasukidwe, ndikupewa delamination yayikulu panthawi yosungira.
Imateteza ku madontho ndi ma sags pakugwiritsa ntchito.
ST, SR mndandanda wa nthawi yomweyo CMC ukhoza kusungunuka kwathunthu mu mphindi 30, kupanga njira yomveka bwino, yowonekera, yofananira ya colloidal, popanda kunyowa kwanthawi yayitali komanso kuyambitsa mwamphamvu.
Zizindikiro zaukadaulo za CMC zokutira:
3. Kugwiritsa ntchito CMC mumakampani a ceramic
Ntchito yayikulu: MB-CMC3 imagwiritsidwa ntchito muzoumba ngati retarder, posungira madzi, thickener ndi stabilizer. Popanga ceramic, amagwiritsidwa ntchito mu thupi la ceramic, glaze slurry ndi kusindikiza kuti apititse patsogolo mphamvu zosinthika za thupi ndikuwongolera kukhazikika kwa glaze slurry.
4. Kugwiritsa ntchito CMC pamakampani ochapa
Detergent grade MB-CMC3: amagwiritsidwa ntchito mu zotsukira kuteteza dothi kuti lisayikidwenso. Mfundo yake ndi yakuti pali kusamvana pakati pa electrostatic repulsion pakati pa dothi loyipiridwa molakwika ndi mamolekyu a CMC omwe amatsatiridwa pansalu. Kuphatikiza apo, CMC imathanso kukulitsa slurry yotsuka kapena sopo ndi kukhazikika kapangidwe kake.
5. Kugwiritsa ntchito CMC pamakampani otsukira mano amankhwala tsiku lililonse
Ntchito yayikulu: MB-CMC3 imayimitsidwa makamaka mumankhwala atsiku ndi tsiku, kuletsa zonyansa kuti zisabwerenso mpweya, kusunga chinyezi, kukhazikika, ndi kukhuthala. Lili ndi ubwino wa kusungunuka mofulumira ndi ntchito yabwino. Zowonjezera ndalama ndi 0.3% -1.0%. Mankhwala otsukira m'mano makamaka amatenga gawo la kuumba ndi kugwirizana. Kupyolera mu kuyanjana kwake kopambana, mankhwala otsukira mano amakhalabe okhazikika ndipo samalekanitsa madzi. Nthawi zambiri, mlingo woyenera ndi 0.5-1.5%.
Six, kukhazikika kwa CMC zomatira mamasukidwe akayendedwe pakapita nthawi, malangizo ntchito
1. Chifukwa cha kulemera kwakukulu kwa maselo a mankhwalawa, pokonzekera MB-CMC3 guluu, nthawi yowonongeka ndi pafupifupi theka la ola kuposa ya CMC wamba;
2. Chifukwa cha kukhuthala kwakukulu kwa guluu pamwamba pa 1.2%, sikoyenera kugwiritsa ntchito ndende yoposa 1.2% pamene CMC imamatira. Nthawi zambiri, ndikofunikira kusankha guluu wokhala ndi pafupifupi 1.0%;
3. Posankha chiŵerengero chowonjezera cha CMC, chiyenera kutsimikiziridwa molingana ndi mtundu wa graphite, malo enieni ndi kuchuluka kwa carbon black (conductive agent) yomwe inatumizidwa, ndipo chiwerengero cha chiŵerengero chowonjezera ndi 0.5% ^ 1.0%;
4. Kuthamanga kwa slurry kumayendetsedwa pafupifupi 2500mPa.s, kutsekemera ndi kusakaniza kwa slurry kudzakhala bwino, zomwe zimathandiza kuti zikhale zofanana ndi zokutira.
Zisanu ndi ziwiri, mawonekedwe azinthu ndi zabwino zake
1. Ili ndi kulemera kwakukulu kwa maselo, omwe amatha kuchepetsa kwambiri kuchuluka kwa CMC yowonjezera, ndipo panthawi imodzimodziyo amatsimikizira kukhuthala ndi kukhazikika kwa slurry;
2. Kuchuluka kwa CMC kuwonjezeredwa mu chilinganizo kumachepetsedwa ndi 1%, zomwe zingathe kuonjezera zomwe zili muzinthu zogwira ntchito ndikuwonjezera mlingo woyenera wa mankhwala;
