PVDF yog ib hom khoom lag luam fluoroplastic. Nws yog qhov luv ntawm polyvinylidene fluoride cob (poly (vinylidene fluoride), uas yog hais txog vinylidene fluoride homopolymer lossis copolymer ntawm vinylidene fluoride thiab lwm yam me me ntawm fluorine-vinyl monomer. Ntxiv rau nws cov tshuaj lom neeg zoo, kev kub tiv taus, oxidation tsis kam, huab cua tsis kam, thiab hluav taws xob tsis kam, nws tseem muaj piezoelectricity, dielectric thaj chaw, pyroelectricity thiab lwm yam khoom tshwj xeeb. cov peev xwm ntau lawm ntau dua 43,000 tons.Qhov daim ntawv thov ntawm polyvinylidene fluoride PVDF resin yog qhov tseem ceeb nyob hauv peb qhov chaw loj ntawm kev lag luam petrochemical, hluav taws xob thiab hluav taws xob thiab fluorocarbon txheej. Polyvinylidene fluoride PVDF resin yog ib qho tseem ceeb tshaj plaws raw khoom rau fluorocarbon txheej. fluorocarbon txheej ua ntej pared los ntawm nws tau tsim rau thib rau tiam. Txij li polyvinylidene fluoride PVDF resin cob muaj huab cua huab cua tsis kam, nws tuaj yeem siv sab nraum zoov siv sijhawm ntev, tsis muaj txij nkawm, hom xim no siv dav hauv chaw nres tsheb fais fab, tshav dav hlau, kev loj, tsev siab siab, thiab lwm yam Ntxiv rau, polyvinylidene fluoride PVDF resin resin tuaj yeem tuaj yeem ua ke nrog lwm cov resins, xws li polyvinylidene fluoride PVDF resin thiab ABS resin kom tau txais cov ntaub ntawv sib xyaw, uas tau siv dav hauv kev tsim kho, kho tsheb kho kom zoo nkauj, khoom siv hauv tsev, thiab lwm yam.
Cov yam ntxwv thiab qhov zoo ntawm PVDF screws:
1. PVDF muaj cov tshuaj tiv thaiv zoo heev, zoo heev tiv taus qhov kub thiab txias thiab oxidation tsis kam.
2. PVDF muaj cov cuab yeej hnav zoo, hloov tau yooj yim, siab tensile lub zog thiab kev cuam tshuam lub zog.
3. PVDF muaj kev tiv thaiv UV zoo heev thiab lub zog hluav taws xob ntau.
4. PVDF tsis muaj hydrophilicity tsis zoo.
5. Cov tshuaj fluorine ua ntoo (feem ntau hu ua thermoplastic Teflon) uas tuaj yeem raug txhaj thiab extruded.
6. Zoo thaum tshav kub kub ua hauj thiab siab dielectric lub zog.
