Qhov ntau ntawm cov residue tsim los ntawmFoundry Txheej Bindertom qab pouring mas yog nyob ntawm cov khoom zoo, hom mis, ntxiv piv thiab cov txheej txheem compatibility. Tsim nyog cov khoom tseem ceeb muaj nyob rau hauv kev lag luam txais tsawg -residue tsim. Raws li cov qauv kev ua haujlwm, cov khoom seem seem tseem qis heev thiab yuav tsis ua rau cov slag qhov lossis slag suav nrog qhov tsis xws luag ntawm castings. Cov khoom seem ntau dhau tsuas yog tshwm sim thaum cov khoom siv tsis zoo siv lossis cov txheej txheem kev khiav haujlwm tsis yog- tus qauv. Zuag qhia tag nrho, cov binders txaus siab cov txheej txheem rau precision casting thiab ntau lawm.
Los ntawm qhov kev xav ntawm cov khoom lag luam, cov khoom siv tsis muaj tshuaj lom neeg tsim cov khoom seem tsawg tshaj plaws. Silica sol, phosphate, dej iav thiab lwm yam inorganic binders feature yooj yim, siab -purity compositions tsis combustible organic impurities. Lawv tsis hlawv los yog carbonize thaum lub sij hawm siab - kub pouring thiab tsuas yog ib tug kab inorganic tshauv tom qab sintering ua ke nrog coatings. Cov tshauv no adheres rau khib molding xuab zeb nto thiab tuaj yeem raug tshem tawm ua ke nrog molding xuab zeb thaum shakeout, NW nyuam qhuav tsim cov residues txuas nrog castings. Vim li no, inorganic binders nyiam rau siab -kawg precision casting. Organic polymer binders xws li hloov kho phenolic resin thiab acrylic binders yuav tag nrho combust thiab decompose rau gaseous tshuaj nrog rau cov pa roj carbon dioxide thiab dej vapor nyob rau hauv qhov kub thiab txias, tsuas yog ib tug kab ntxhia impurities nrog negligible residue ntim.
Cov seem seem feem ntau yog los ntawm cov khoom tsis zoo thiab kev ua haujlwm tsis tu ncua. Pheej yig qis- qib binders suav nrog ntau cov khoom siv inert xws li calcium carbonate thiab talcum hmoov, nrog rau cov monomers tsis huv, cov kua nplaum seem thiab cov khoom tsis huv. Cov khoom no tsis tuaj yeem decompose ntawm qhov kub thiab txias thiab khaws cov hmoov tshauv loj thiab cov pa roj carbon slag tom qab nchuav. Lub caij no, cov neeg ua haujlwm dig muag ntxiv ntau dhau Foundry Coating Binder los txhim kho txheej adhesion, ua rau cov organic thiab inert feem ntau nyob rau hauv txheej txheej txheej. Cov khoom seem tsis tuaj yeem ua rau muaj qhov kub thiab txias, sib sau ua ke rau hauv cov khoom seem, ntab rau saum npoo ntawm cov hlau molten thiab daim ntawv slag inclusions thiab slag qhov tom qab solidification.
Tsis tas li ntawd, qhov sib npaug tsis sib haum thiab kev kho tsis tiav kuj ua rau cov khoom seem seem. Tsis zoo sib xws ntawm Foundry Coating Binder thiab txheej tshem tawm cov neeg ua haujlwm, defoamers lossis cov hmoov refractory ua rau agglomeration thiab sedimentation. Tom qab txhuam hniav, ib nrab tsub zuj zuj ntawm cov khoom tshwm sim ntawm txheej txheej, tsim kom muaj cov seem seem hauv cov cheeb tsam sib sau thaum lub sij hawm nchuav. Coatings nrog tsis tiav curing ntxiab unreacted binder monomers nyob rau hauv. Cov monomers decompose sai sai thaum rhuab thaum lub sij hawm pouring thiab yooj yim tsim flocculent residues adhering rau puab kab noj hniav thiab nto ntawm castings, ua kom huv si workload.
Raws li cov txheej txheem txheej txheem, xaiv qib siab -purity industrial-qib Foundry Coating Binder, nruj me ntsis raws li cov txheej txheem ntxiv, sib tov cov ntaub ntawv kom huv si thiab ua kom tiav txheej txheej yuav ua rau yuav luag tsis pom qhov seem tom qab nchuav. Tsuas yog cov hmoov tshauv tshem tawm tsuas yog nyob rau ntawm cov xuab zeb pov tseg thiab tsis cuam tshuam qhov zoo ntawm casting. Piv nrog cov resin xuab zeb curing agents thiab riser additives ntawm casting raw thiab auxiliary cov ntaub ntawv, Foundry Txheej Binder generates deb tsawg residue thiab tsis categorized raws li ib tug siab - residue- cov khoom txaus ntshai.
