Delamination ntawmFoundry Txheej Binderthaum lub sij hawm ntev - lub sij hawm cia yog qhov dav thiab ib txwm tshwm sim ntawm lub cev. Feem ntau cov dej-raws li thiab hnyav-raws li cov binders tshwj xeeb rau cov ntawv thov foundry ntsib cov teeb meem no, tsuas yog sib txawv ntawm tus nqi thiab qib ntawm stratification es tsis qhia cov khoom tsis xws luag. Cov qauv txheej txheem ntawm Foundry Txheej Binder tsis yog ib homogeneous kua. Nws yog ib qho sib xyaw colloidal sib xyaw ua ke ntawm cov khoom sib txuas, cov khoom siv inorganic, tshem tawm cov additives, cov kuab tshuaj, cov tshuaj ntub dej thiab lwm yam khoom xyaw. Qhov sib txawv ntawm qhov ntom ntom, qhov hnyav molecular thiab particle loj ntawm cov khoom no yog qhov tseem ceeb ntawm kev delamination.
Thaum lub sij hawm ntev static cia, nyob rau hauv lub gravitational quab yuam, ntom inorganic hmoov thiab tawv fillers nyob rau hauv lub system maj mam tog thiab accumulate nyob rau hauv qab ntawm lub thawv. Hauv qhov sib piv, qis- cov khoom ntom ntom xws li cov tshuaj resin, cov kuab tshuaj thiab cov tshuaj defoaming ntxiv mus rau sab sauv, thaum kawg tsim cov txheej txheem txheej nrog cov kua ntshiab rau saum thiab cov av tuab hauv qab. Feem ntau, stratification tshwm sim maj mam tom qab kaw cia ntawm qhov kub thiab txias rau 1 mus rau 3 lub hlis, thiab pom tseeb tom qab ntau tshaj li ib nrab xyoo ntawm kev cia.
Cia tej yam kev mob cuam tshuam ncaj qha rau stratification ceev. Kub ambient kub accelerates molecular zog nyob rau hauv lub system, impairs colloidal ncua kev kawm ntawv stability thiab speeds li tiv thaiv kev sib hais haum. Tsis tshua muaj kub txo cov kev ua ub no ntxiv thiab unbalances lub ncua kev kawm ntawv system, uas kuj aggravates delamination. Kev hloov pauv kub tsis tu ncua, tsis tiav sealing tom qab qhib thiab impurity paug yuav ua rau kom cov sedimentation thiab txawm tias caking. Ntawm qhov tsis sib xws, qhov tsis tu ncua - qhov kub thiab txias ntim cia hauv qhov chaw txias thiab qhuav ib puag ncig tuaj yeem ua rau qeeb delamination.
Nws yog ib qho tseem ceeb kom paub qhov txawv tias delamination sawv cev rau kev sib cais ntawm lub cev rov qab tsis yog tshuaj lom neeg deterioration. Tom qab stratification, Cheebtsam yog unevenly faib, tseem core bonding pab pawg neeg thiab chemical zog tseem unchanged. Tag nrho do lub binder kom rov ua kom lub xeev homogeneous ua ntej daim ntawv thov; cov cim suav nrog kev sib txuas ntawm lub zog, kev ua tau zoo thiab kev txhuam hniav yuav rov qab mus rau qhov qub, ua tau raws li qhov xav tau ntawm daim ntawv thov txheej txheej. Txawm li cas los xij, yog tias cov ntaub ntawv txheej raug tso tseg tsis kho rau lub sijhawm ntev, cov av hauv qab yuav compact thiab tsim cov tawv tawv, me ntsis cuam tshuam rau daim ntawv thov. Yog li ntawd, ua tib zoo do Foundry Txheej Binder khaws cia rau lub sijhawm ntev ua ntej siv.
