Yog vim li cas koj Glaze Slurry cais, nyob, lossis Thixotropes: Qhov teeb meem tiag tiag yog koj tus neeg sawv cev ncua "Structure"
"Chuan, kuv glaze slurry tsis tuaj yeem ua haujlwm nrog. Thaum kuv npaj ua ntej, nws zoo heev. Tab sis tom qab ob lossis peb hnub, muaj cov dej ntshiab saum toj, cov av tawv tawv hauv qab, thiab cov ntxhiab tsw qab hauv nruab nrab. Cov neeg ua haujlwm hais tias nws tuab dhau los ua kom zoo. Thaum lawv muab tshuaj tsuag, cov glaze npog tsis sib npaug -qee qhov chaw tsaus dua 5} qee qhov ntau dua 'thiab ntau dua.
Nws sim hloov CMC hom, ntxiv cov tshuaj tua kab mob, thiab txawm tias txuas ntxiv pob -milling lub sij hawm ib nrab teev. Tsis muaj dab tsi ua haujlwm.
Nws nug kuv tias:
"Puas yog vim huab cua kub thiab muaj cov kab mob ntau dhau?"
kuv hais rau nws tias:
Thaum tshav kub kub tsuas yog ib qho catalyst xwb. Qhov teeb meem tiag tiag tsis yog kab mob. Qhov teeb meem tiag tiag yog tias koj tus neeg sawv cev ncua tsis tau tswj hwm los txhawb cov glaze slurry.
Hnub no, kuv yuav piav qhia qhov no siv ob yam ntaub ntawv: Halloysite thiab siab -whiteness bentonite.
Yuav ua li cas tshwm sim thaum koj Glaze Slurry "mus phem"?
Yog tias koj tawm ntawm qhov npaj glaze slurry sawv rau ob hnub,
koj yuav pom ib qho ntawm peb qhov teeb meem:
Hard Sediment
Cov khoom hnyav xws li feldspar, quartz, thiab frit nyob rau hauv qab thiab tsim ib txheej nyuaj uas nyuaj rau rov qab - ncua.
Qhov no tshwm sim vim tias tus neeg sawv cev ncua tsis muaj lub zog txaus los tuav cov khoom hauv qhov chaw.
Dej-Glaze Separation
Cov dej ntshiab ntab mus rau saum npoo, thaum txheej qis dhau los ua taum -curd- zoo li.
Qhov no yog qhov mob hnyav tshaj plaws.
Nws txhais tau hais tias lub network qauv ntawm kev ncua kev kaw lus tau tawg tag, thiab dej tau sib cais los ntawm cov khib nyiab.
Thixotropy ntau dhau
Thaum freshly stirred, lub slurry yuav nyias thiab kua. Tab sis tom qab sawv ntsug rau ib nrab ib teev, nws ua tuab heev, zoo li muab tshuaj txhuam.
Nyob rau hauv cov ntaub ntawv no, lub glaze yuav tsis tsuag smoothly, thiab lub txheej yuav tsis ntws tusyees thaum glazing.
Yog tias tseem muaj ntxhiab tsw ntxhiab lossis ua npuas dej, cov khoom siv organic xws li CMC yuav raug decomposed los ntawm cov kab mob.
Vim li cas Cov Neeg Sawv Cev Tso Cai Lij Choj Ib txwm muaj mob taub hau?
Peb daws teeb meem kev ncua yav dhau los li cas? Peb ntxiv CMC, bentonite, lossis kaolin. Txhua tus ntawm lawv muaj nws tus kheej cov teeb meem.
CMC:pheej yig thiab siv tau yooj yim, tab sis nws yog cov khoom siv "me me". Nws yog rhiab heev rau acids, alkalis, kub kub, thiab kab mob. Thaum lub caij ntuj sov, nws tuaj yeem qaub tom qab tsuas yog ob hnub. Tsis tas li ntawd, nws tso siab rau molecular saw entanglement. Thaum raug shear quab yuam xws li nplawm thiab siv, cov saw hlau molecular tawg, thiab cov nyhuv ncua kev kawm poob qis.
Feem ntau bentonite(xws li cov uas ua nyob rau hauv Liaoning thiab Inner Mongolia): Nws muaj zog thickening zog, tab sis nws yog greyish - daj nyob rau hauv cov xim thiab muaj ntau ntau ntawm hlau thiab titanium impurities. Yog tias koj ntxiv nws rau dawb glaze, lub ntsej muag glaze yuav ua qias neeg. Ntxiv mus, nws yuav tsum tau hloov kho sodium; Txwv tsis pub, nws cov dej nqus thiab o ua haujlwm yuav tsis zoo.
Ordinary kaolin:Nws qhov dawb tuaj yeem ua tau, tab sis nws muaj lub phaj -zoo li qauv. Hauv dej, cov phaj- zoo li cov khoom zoo li ib pawg ntawm cov phaj- ib zaug ntxuav los ntawm dej, lawv tawg thiab tsis tuaj yeem txhawb cov khoom hnyav. Tias yog vim li cas ntau tus neeg hais tias: "Txawm li cas los xij kuv ntxiv kaolin, lub glaze tseem nyob."
Yog li, puas muaj cov khoom siv uas tsis yog - tshuaj lom, tsis yog - putrefactive, tsis yog - ploj, thiab ib txwm muaj "network qauv" uas tuaj yeem xauv cov khoom kom ruaj khov?
Yog, muaj. Tsis ntev los no, kuv tau kawm ib hom ntxhia -Kuv hu nws Suspending Agent No. 1.
Kuv Mineral: Tubular Structure, Ib txwm "Woaving Network"
Cia kuv pib nrog ib qho piv txwv yooj yim. Koj puas tau pom ib pawg straws?
Thaum nchuav ua ke randomly, lawv interpenetrate thiab entangle nrog ib leeg, tsim ib tug xoob "yarn pob." Cov dej tuaj yeem dhau mus, tab sis cov khoom loj loj raug kaw thiab tsis tuaj yeem nyob.
Cov ntxhia kuv tab tom tham txog coj raws nraim li cov "straws."
Nws cov tshuaj muaj pes tsawg leeg yog tib yam li kaolin, tab sis nws cov muaju yog tubular, tsis yog phaj -zoo li. Cov nanotubes no muaj ob peb puas nanometers ntev thiab kaum nanometers hauv txoj kab uas hla -zoo li me me hollow straws.
Ib txwm kaolin yog phaj -zoo li, zoo li ib pawg ntawm daim hlau. Cov ntxhia no yog tubular, zoo li pawg straws. Cov phaj sib xyaw ua ke yuav tawg thaum ntxuav los ntawm dej; straws entangled ua ke nyob twj ywm tsis tu ncua txawm tias thaum yaug. Qhov no yog qhov laj thawj tseem ceeb rau nws qhov kev ua tau zoo ntawm kev ncua.
Tshawb xyuas cov ntaub ntawv xeem
Hauv qab no yog daim ntawv pov thawj kev soj ntsuam ntawm cov khoom no tuaj txawv teb chaws (saib daim duab):
Poob ntawm Ignition (LOI): 15.74%
Tus nqi qis: 38.05%
SiO₂: 44.28%
Fe₂O₃: 0.61% (tsawg heev, tsis muaj kev phiv cuam tshuam rau whiteness)
Lwm yam impurities: tsawg dua 0.1%
Nws nta siab dawb thiab tsis tshua muaj hlau & titanium cov ntsiab lus, haum rau cov glaze dawb thiab pob tshab daim ntaub ntawv. Kev sib piv ntawm Ordinary Kaolin thiab Halloysite (Suspending Agent No.1)
| Yam ntxwv | Ordinary Kaolin | Halloysite (Suspend Agent No.1) |
|---|---|---|
| Crystal Morphology | Phaj -zoo li (zoo li daim hlau) | Tubular (zoo li straws) |
| Suspension Mechanism | Relies ntawm qhov loj me me, nws yooj yim rau kev daws teeb meem | Tsim ib lub 3D network rau lub cev particle ntxiab |
| Kev cuam tshuam rau Whiteness | Zoo | Superior (qis hlau & titanium cov ntsiab lus) |
| Resistance to Bacterial Degradation | Ntuj ntxhia, tsis yog -biodegradable / non-putrefactive | Ntuj ntxhia, tsis yog -biodegradable / non-putrefactive |
| rhiab heev rau Shear Force | Insensitive | Insensitive (tsis txhob hla pob-milling) |
| Nqe | Tus nqi qis | Imported, kuj tus nqi siab |
Cov Mineral no: Siab -Whiteness Bentonite - Thickens, Txhim kho lub zog, thiab yuav tsis muaj kab mob Glaze nto
Suspending Agent No.1 excels ntawm kev txhawb nqa cov khoom, tab sis nws lub peev xwm thickening yog txwv. Yog tias koj xav tau ntxiv glaze slurry viscosity (piv txwv li, txhawm rau tiv thaiv glaze khiav thiab txhim kho lub zog zais), koj yuav xav tau cov khoom siv ntxiv: siab -whiteness bentonite.
Qhov no tsis yog ib qho grey - daj bentonite. Nws yog ib qho ntxhia ib txwm txuam nrog kaolin. Qhov ntawd txhais tau hais tias nws muaj ob qho tib si montmorillonite (lub thickening tivthaiv ntawm bentonite) thiab siab -alumina, siab- dawb paug feem ntawm kaolin.
Thickening muaj nuj nqi: Montmorillonite swells thaum sib cuag nrog dej los tsim ib lub network denser, ntxiv rau halloysite.
Siab dawb: Raws li nws coexists lawm nrog kaolin, hlau thiab titanium impurities yog diluted. Nws yog deb tshaj li cov pa bentonite thiab yuav tsis qhia daj lossis grey discoloration thaum ntxiv rau dawb glaze.
Siab zog: Nws cov ntsiab lus alumina siab (muab los ntawm kaolin) txhim kho lub hardness thiab hnav tsis kam ntawm qhov hluav taws kub glaze nto.
Peb tsis muaj nws daim ntawv pov thawj kev soj ntsuam tag nrho, tab sis qhov kev ntsuam xyuas pom tau tias nws cov xim dawb mus txog ze li ntawm 85, thiab nws cov ntsiab lus hlau yog kwv yees li ib nrab ntawm cov bentonite zoo tib yam. Nws tuaj yeem siv tau zoo rau cov glaze dawb thiab pob tshab glaze.
Thaum sib xyaw nrog peb tus neeg sawv cev ncua ntawm qhov sib piv ntawm 1: 1 thiab ntxiv rau glaze slurry, qhov kev sib xyaw ua ke muab ntau yam txiaj ntsig: tsis muaj teeb meem, tsis muaj dej -glaze sib cais, zoo haum rau ob qho tib si tshuaj tsuag glazing thiab curtain glazing, thiab siab raug rho tawm haujlwm glaze zog. Ob qho tib si yog cov ntxhia hauv ntuj, zam qhov tsis zoo cuam tshuam nrog CMC.
Yuav siv li cas? Peb Cov Lus Pom Zoo
Npaj 1: daws Sedimentation nkaus xwb
Siv Halloysite ib leeg. Dosage: 0.5-1.0% raws li qhov hnyav ntawm cov khoom siv glaze qhuav.
Pob milling ceeb toom: Halloysite zoo, thiab nws cov qauv tubular tuaj yeem raug puas los ntawm ntau tshaj - sib tsoo. Nws raug pom zoo kom pob zeb lwm cov ntaub ntawv raw ua ntej, tom qab ntawd ntxiv halloysite rau me me dispersion nyob rau hauv lub xeem 30-60 feeb. Yog hais tias Halloysite yuav tsum tau ntxiv los ntawm qhov pib ntawm pob milling, txo tag nrho lub sij hawm milling los ntawm 10-15%, thiab xyuas kom meej qhov kev ncua kev kawm ntawv ntawm me me batch xeem.
Npaj 2: Tiv thaiv sedimentation & nce viscosity
Blend halloysite thiab siab -whiteness bentonite ntawm 1: 1 piv, tag nrho cov tshuaj: 0.8–1.5%. Halloysite tsim lub hauv paus ntsiab lus hauv lub network thaum bentonite sau cov pores network. Ob qho khoom siv tuaj yeem muab ntxiv ua ke thaum lub pob milling, tab sis halloysite tseem pom zoo kom ntxiv rau theem tom ntej.
Npaj 3: Hloov CMC tag nrho
Yog tias koj muaj teeb meem los ntawm CMC spoilage thiab kev ua haujlwm tsis ua haujlwm, CMC tuaj yeem hloov tau tag nrho nrog rau lub halloysite + siab -whiteness bentonite system. Txawm li cas los xij, koj yuav tsum rov ua dua - kho qhov ntsuas rheological ntawm glaze slurry. Kev sim me me tau pom zoo ua ntej.
Kev Ceeb Toom Tseem Ceeb
Thaum siv cov ntaub ntawv tshiab thawj zaug, ib txwm ua cov qauv me me ua ntej cov khoom tsim tawm kom paub meej tias kev ncua kev ruaj ntseg thiab raug rho tawm haujlwm glaze zoo.
Tsis muaj universal khoom; tsuas yog cov txheej txheem uas phim koj cov qauv. Halloysite los nrog tus nqi siab dua, tab sis nws qhov kev xav tau ntau npaum li cas tsawg, ua rau muaj kev txwv tsis pub nce nqi tag nrho.
Ntau tus neeg siv khoom pom tias nws raug nqi - ua haujlwm tau zoo thaum lawv suav cov nyiaj khaws cia los ntawm kev txo qis rov ua dua thiab cov khoom tsis lees paub.
Kev xav zaum kawg
Cia kuv qhia qee qhov kev nkag siab ncaj ncees. Kuv tau paub me ntsis txog "tubular structures" lossis "nano networks". Rov qab thaum ntawd, kuv xav tias cov neeg raug tshem tawm tsuas yog av nplaum ntxiv rau CMC.
Tom qab suav tsis txheeb nug los ntawm cov neeg siv khoom, kuv tau siv sijhawm ntau los tshuaj xyuas cov ntaub ntawv thiab khiav cov kev sim ua tau zoo. Thaum kawg, kuv pom tau hais tias: ncua kev kawm ntawv tsis yog nyob ntawm viscosity lossis "stickiness", tab sis ntawm ib qhonetwork qauv.
Phaj-zoo li kaolin zoo tib yam zoo li lub tsho nuv ntses uas hnav nrog qhov loj mesh qhib, los ntawm cov khoom hnyav hnyav dhau mus. Halloysite, los ntawm qhov sib txawv, ua zoo li zoo elastic stockings - nws nta me me, saj zawg zog mesh rau ntxiab hais kom ntseeg tau.
Ntau xyoo ntawm glaze formulation ua hauj lwm, kuv tau loj hlob convinced: xaiv ib yam khoom uas zoo microstructure teeb meem ntau tshaj qhov kawg tweaking npaum li cas ratios.
Chuan
Kuv yog Chuan, tus kws tshaj lij ceramic glaze uas nws lub chaw ua haujlwm tau ntim nrog ntau cov qauv av nplaum. Kuv siv sijhawm ntau ntawm kuv lub sijhawm sib xyaw thiab sim glaze slurries.
Yog tias koj muaj teeb meem los ntawm kev ua kom lub ntsej muag tsis zoo-cov teeb meem ntsig txog, thov xa koj cov ntaub ntawv xov xwm rau kuv, thiab kuv yuav pab txheeb xyuas nrog koj.
Yog tias koj pom cov ntawv no muaj txiaj ntsig, thov nyiam, tawm lus thiab qhia rau cov phooj ywg xav tau. Koj txoj kev koom tes txhawb kuv kom nthuav tawm ntau cov ncauj lus qhia rau koj. Nyob twj ywm rau peb tsab xov xwm tom ntej.
