Dab tsi ntawmCastable polyurethane PrepolymersBeiqiao ua dab tsi?
Castable polyurethane propolymers tau dhau los ua ib feem tsis tseem ceeb ntawm cov ntaub ntawv muaj kev lag luam niaj hnub. Ntawm beiqiao, peb tsom rau kev tsim khoom thiab kev loj hlob ntawm cov ntaub ntawv polyurethane, muaj xws li castures polyurethane expored rau kev ua tau zoo tshwj xeeb cov kev xav tau, thiab ib pab ntxiv. Cov ntaub ntawv no tau siv dav thoob cov haujlwm xws li Machinery, textiles, mining, thiab roj av. In recent years, they have also been applied in newer fields like photovoltaics, printing, sports equipment, automotive, marine, and defense-related industries.
Peb cov kab khoom tam sim no suav nrog:
1. Ciajtable Polyurethane Prepolymers
Peb muab ob qho tib si polyester - Raws thiab polyet - Raws li cov khoom TDI thiab MDI. Rau cov ntawv teev tshwj xeeb, peb kuj muab cov tswv yim ua haujlwm ua ke nrog NDI lossis PPDI thiab Customized ester / ether txheej txheem. Cov ntaub ntawv no tau tsim los tswj cov kev ua tau zoo nyob rau hauv ntau yam kev xav tau.
2. Polyurethane ob -} cov tshuab sib xyaw
Gel - hom khoom
Amazient - kev kho cov potting tebchaw
Tsawg - viscosity dripping adhesives
3. High {{{}} Kev Ua Ntej Prepolymers
Tsim rau cov ntawv thov uas muaj cov kev ua tau zoo yuav tsum muaj, cov no suav nrog:
Siab heev hardness
Kev ua tau zoo heev thiab rov ua dua
High tensile thiab rhuav lub zog
Tsawg cua kub tsim nyob rau hauv kev ntxhov siab thiab kev ua haujlwm zoo compression
Txhim Kho Hydrolysis Kuj Thiab Tsawg - kub yooj yim
Kuj rau cov kuab tshuaj thiab nce qhov kub
4. Cov ntawv thov tshwj xeeb
Peb cov pab pawg kws tshaj lij kuj tseem txhim kho cov kev daws teeb meem rau:
High - thau khoom, siab -}} kev siv cov tub luam
High - Lub zog prepolymers rau photovoltaic encapsululation thiab txheej
Npaj rau pwm - dawb, tig casting Systems
Tau ntau xyoo, peb cov khoom tau raug xa tawm mus rau ntau lub tebchaws hauv Asia, Tebchaws Middle, Africa, Earge American, tau txais lub koob npe nrov hauv cov neeg siv hauv ntau pawg.
Keeb kwm ntawm Polyurethane Dates Rov qab mus rau xyoo 1937, thaum xibfwb Otto Bayer hauv lub teb chaws Yelemees thawj synthesized polymers uas muaj urethane sib txuas hauv lawv cov saw hlau tseem ceeb. Txij thaum ntawd los, Polyurethane cov ntaub ntawv tau hloov zuj zus thiab tam sim no yog ib qho ntawm feem ntau cov polymers hauv ntiaj teb.
