Polyurethane elastomeryog cov khoom siv polymer ntawm cov yas thiab roj hmab rau cov khoom ntub dej ntawm slurry twj tso kua mis, thiab nws cov qauv molecular muaj cov polymer nrog cov saw txuas ntxiv ntawm cov amino acid esters. Nws yog maj mam polymerized los ntawm isocyanate monomers thiab cov tebchaw uas muaj cov tshuaj chlorine.
Vim yog cov qauv molecular ntawm polyurethane elastomer uas muaj ntau cov polar bonds thiab ruaj khov chlorine bonds ntawm molecules, nws muaj ntau yam zoo heev, tshwj xeeb tshaj yog zoo lub cev thiab txhua yam khoom thiab hnav tsis kam.
Polyurethane elastomermuaj lub cev thiab txhua yam khoom zoo ib yam li roj hmab, nrog rau kev ua thiab tsim cov yam ntxwv zoo ib yam li yas.
Qhov zoo ntawmPolyurethane elastomer raws li cov khoom ntawm wetted qhov chaw ntawm slurry twj tso kua mis:
1) Dav adjustable ntau yam ntawm kev ua tau zoo. Ntau qhov ntsuas lub cev thiab kev ua haujlwm txhua yam tuaj yeem sib txawv hauv qee qhov ntau los ntawm kev xaiv cov khoom siv raw thiab kev hloov kho ntawm cov khoom sib xyaw, yog li ua tau raws li qhov sib txawv ntawm cov neeg siv khoom.
(2) Kev ua tau zoo heev ntawm kev hnav tsis kam raws li wetted ib feem ntawm slurry twj tso kua mis. Tshwj xeeb tshaj yog nyob rau hauv kev ua hauj lwm nrog wetting xov xwm xws li dej thiab roj, nws hnav tsis kam yog feem ntau ob peb mus rau kaum ntawm lub sij hawm raws li cov khoom siv roj hmab zoo tib yam.
(3) Processability. Polyurethane elastomeric cov khoom tuaj yeem ua cov txheej txheem xws li tig, milling, thiab drilling.
Polyurethane elastomermuaj kev ua haujlwm zoo heev thaum thov rau slurry twj tso kua mis wetted qhov chaw.Tam sim no cia peb piv polyurethane elastormer nrog siab chrome
cam khwb cia hlau thiab roj hmab.
Polyurethane elastomer VS siab chrome cam khwb cia hlau ua cov khoom ntawm wetted ib feem ntawm slurry twj tso kua mis
1) Lifespan: Polyurethane elastomer muaj 6 ~ 10 zaug lifespan raws li qhov siab chromium cam khwb cia hlau thaum siv cov av nkos, thiab 3 zaug li lub neej ntawm siab chromium cam khwb cia hlau thaum siv slurry twj.
(2) Qhov hnyav ntawm lub slurry twj tso kua mis impeller ua los ntawm polyurethane yog heev txo, thiab nto ntawm lub wetted ib feem ntawm slurry twj yog du, txo hluav taws xob noj thaum lub sij hawm tig. Yog li ntawd, nws tuaj yeem txuag tau li ntawm 20% ntawm hluav taws xob thiab txhim kho kev ua haujlwm ntawm lub tshuab nqus tsev twj los ntawm 5% mus rau 10%. Nyob rau tib lub sijhawm, qhov hnyav ntawm lub rotor kuj tseem txuas ntxiv lub neej kev pabcuam ntawm cov kabmob, txo qhov ua haujlwm tsis ua haujlwm ntawm lub twj tso kua mis, txo cov nqi tu, thiab txo qis kev poob qis los ntawm kev saib xyuas.
(3) Polyurethane muaj kev vibration zoo thiab kev ua haujlwm zoo, uas tuaj yeem txo cov twj tso kua mis kev co thiab suab nrov rau qee yam.
Polyurethane elastomer VS roj hmab raws li cov khoom ntawm wetted ib feem ntawm slurry twj tso kua mis
1) Polyurethane muaj qhov nyuaj ntawm qhov dav ntawm 20 mus rau saum toj 95 (Shore A). Polyurethane tseem elastic nrog elongation ntawm siab hardness degree, thaum ntau cov ntim yuav tsum tov nrog roj hmab ntawm tus nqi ntawm kev txo elasticity thiab kev ua haujlwm.
2) Polyurethane muaj kev ua tau zoo dua ntawm lub zog tsim kua muag thiab li 2 npaug ntawm cov roj hmab ntuj.
(3) Kev hnav tsis kam ntawm polyurethane yog li ntawm 3-5 npaug ntawm cov roj hmab ntuj.
(4) Polyurethane wetted qhov chaw tuaj yeem raug txiav thiab ua haujlwm nyob rau hauv qee qhov nyuaj.
(5) Polyurethane yog dyeable thiab tuaj yeem ua rau cov khoom ntawm txhua yam xim.
