Kumvetsetsa CMC ndi Udindo Wake mu Glaze Slurry
Carboxymethyl Cellulose (CMC) ndi polima yosungunuka m'madzi yochokera ku cellulose. Amagwiritsidwa ntchito kwambiri mu glazes za ceramic monga binder ndi rheology modifier. CMC bwino glaze a mamasukidwe akayendedwe, kuthandiza kukhala mogwirizana kuyimitsidwa kwa particles. Imawonjezeranso kumatirira kwa glaze pamwamba pa ceramic ndikuchepetsa zolakwika monga ma pinholes ndi zokwawa.
Zinthu Zofunika Zomwe Zikukhudza CMC Glaze Slurry Kukhazikika
Ubwino wa CMC ndi Kukhazikika:
Chiyero: CMC yoyera kwambiri iyenera kugwiritsidwa ntchito kupewa zonyansa zomwe zitha kusokoneza matope.
Degree of Substitution (DS): DS ya CMC, yomwe imasonyeza kuchuluka kwa magulu a carboxymethyl omwe amamangiriridwa pamsana wa cellulose, imakhudza kusungunuka kwake ndi ntchito yake. A DS pakati pa 0.7 ndi 1.2 nthawi zambiri ndiyoyenera kugwiritsa ntchito ceramic.
Kulemera kwa Mamolekyulu: Kulemera kwa maselo a CMC kumapereka kukhuthala kwabwinoko komanso kuyimitsidwa, koma kumatha kukhala kovuta kusungunuka. Kulinganiza kulemera kwa mamolekyu ndi kuwongolera kosavuta ndikofunikira.
Ubwino wa Madzi:
PH: PH ya madzi omwe amagwiritsidwa ntchito pokonzekera slurry iyenera kukhala yosalowerera pang'ono ya alkaline (pH 7-8). Madzi a asidi kapena amchere kwambiri amatha kusokoneza kukhazikika ndi magwiridwe antchito a CMC.
Zomwe zili mu Ionic: Kuchuluka kwa mchere wosungunuka ndi ayoni kumatha kuyanjana ndi CMC ndikukhudza kukhuthala kwake. Kugwiritsa ntchito madzi a deionized kapena ofewa nthawi zambiri kumalimbikitsidwa.
Njira Yokonzekera:
Kusungunuka: CMC iyenera kusungunuka bwino m'madzi musanawonjezere zigawo zina. Kuwonjezera pang'onopang'ono ndi kusonkhezera mwamphamvu kungalepheretse kupanga zotupa.
Kusakaniza Dongosolo: Kuwonjezera yankho la CMC pazida zosakanikirana zosakanikirana kapena mosemphanitsa kungakhudze homogeneity ndi kukhazikika. Nthawi zambiri, kusungunula CMC kaye kenako ndikuwonjezera zinthu zonyezimira kumabweretsa zotsatira zabwino.
Kukalamba: Kulola yankho la CMC kukalamba kwa maola angapo musanagwiritse ntchito kumatha kusintha magwiridwe ake powonetsetsa kuti madzi akumwa ndi kusungunuka kwathunthu.
Zowonjezera ndi Zochita Zawo:
Deflocculants: Kuonjezera zochepa za deflocculants monga sodium silicate kapena sodium carbonate kungathandize kufalitsa tinthu mofanana. Komabe, kugwiritsa ntchito mopitirira muyeso kungayambitse kutsika kwambiri komanso kusokoneza slurry.
Zoteteza: Pofuna kupewa kukula kwa tizilombo toyambitsa matenda, zomwe zingawononge CMC, zotetezera monga biocides zingakhale zofunikira, makamaka ngati slurry yasungidwa kwa nthawi yaitali.
Ma polima Ena: Nthawi zina, ma polima ena kapena zokhuthala zimagwiritsidwa ntchito molumikizana ndi CMC kukonza bwino rheology ndi kukhazikika kwa glaze slurry.
Njira Zothandizira Kukhazikika kwa CMC Glaze Slurry
Konzani Kuyikira kwa CMC:
Dziwani kuchuluka koyenera kwa CMC pamapangidwe anu enieni a glaze poyesera. Kuyika kofananira kumayambira 0.2% mpaka 1.0% pa kulemera kwa kusakaniza kowuma kwa glaze.
Pang'onopang'ono sinthani ndende ya CMC ndikuwona kukhuthala ndi kuyimitsidwa kuti mupeze zoyenera.
Kuonetsetsa Kusakanikirana Kwachikale:
Gwiritsani ntchito zosakaniza zometa ubweya wambiri kapena mphero kuti mutsimikizire kusakanikirana bwino kwa CMC ndi zigawo za glaze.
Nthawi ndi nthawi yang'anani slurry kuti ifanane ndikusintha magawo osakanikirana ngati pakufunika.
Kuwongolera pH:
Kuwunika pafupipafupi ndikusintha pH ya slurry. Ngati pH ichoka pamtundu womwe mukufuna, gwiritsani ntchito mabafa oyenera kuti mukhale bata.
Pewani kuwonjezera zinthu za acidic kapena zamchere kwambiri mu slurry popanda kubisa bwino.
Kuwunika ndi Kusintha Viscosity:
Gwiritsani ntchito ma viscometers kuti muwone kukhuthala kwa slurry nthawi zonse. Sungani chipika cha ma viscosity kuwerenga kuti muzindikire zomwe zikuchitika komanso zovuta zomwe zingachitike.
Ngati mamasukidwe akayendedwe akusintha pakapita nthawi, sinthani powonjezera madzi pang'ono kapena njira ya CMC ngati pakufunika.
Kusunga ndi Kusamalira:
Sungani slurry muzitsulo zovundikira, zoyera kuti zisaipitsidwe ndi kutuluka nthunzi.
Nthawi zonse kusonkhezera kusungidwa slurry kukhala kuyimitsidwa. Gwiritsani ntchito makina osonkhezera ngati kuli kofunikira.
Pewani kusungirako nthawi yayitali pa kutentha kwambiri kapena padzuwa, zomwe zingawononge CMC.
Kuthetsa Mavuto Odziwika
Kukhazikitsa:
Ngati tinthu takhazikika mwachangu, yang'anani kuchuluka kwa CMC ndikuwonetsetsa kuti ndi madzi okwanira.
Taganizirani kuwonjezera pang'ono deflocculant kusintha tinthu kuyimitsidwa.
Gelation:
Ngati slurry gels, zingasonyeze over-flocculation kapena kwambiri CMC. Sinthani ndende ndikuyang'ana ma ionic omwe ali m'madzi.
Onetsetsani dongosolo lolondola la njira zowonjezera ndi zosakaniza.
Kuchita thovu:
Foam ikhoza kukhala vuto pakusakaniza. Gwiritsani ntchito antifoaming agents mosamala kuti muchepetse chithovu popanda kuwononga mawonekedwe a glaze.
Kukula kwa Microbial:
Ngati slurry akupanga fungo kapena kusintha kugwirizana, zikhoza kukhala chifukwa tizilombo tating'onoting'ono ntchito. Onjezani mankhwala ophera tizilombo ndipo onetsetsani kuti zotengera ndi zida zaukhondo.
Kukwaniritsa kukhazikika kwa CMC glaze slurry kumaphatikizapo kuphatikiza kusankha zinthu zoyenera, kuwongolera njira yokonzekera, ndikusunga kasungidwe koyenera ndi kasamalidwe. Pomvetsetsa gawo la gawo lililonse ndikuwunika magawo ofunikira monga pH, kukhuthala, ndi kuyimitsidwa kwa tinthu, mutha kupanga slurry yokhazikika komanso yapamwamba kwambiri. Kuthetsa mavuto nthawi zonse ndikusintha kutengera magwiridwe antchito kumathandizira kuti zinthu za ceramic zikhale zosasinthika komanso zabwino.
