VDF
Vinylidene fluoride (VDF) sida caadiga ah waa mid aan midab lahayn, aan sun ahayn, oo guban karta, waxayna leedahay ur yar oo ether ah. Waa mid ka mid ah monomers muhiim ah oo ka mid ah walxaha polymer-ka sare ee fluoro oo leh jinsi caadi ah oo olefin ah, awoodna u leh polymerizing iyo copolymerizing. Waxaa loo isticmaalaa diyaarinta ee monomer ama polymer iyo isku-dhafka dhexdhexaadka ah.

Codsiga
VDF sida monomer-ka fluorine ee muhiimka ah, waxay diyaarin kartaa polyvinylidene fluoride resin (PVDF) iyada oo loo marayo hal polymerization, iyo diyaarinta F26 fluororubber iyada oo loo marayo polymerizing with perfluoropropene, ama F246 fluororubber by polymerizing with tetrafluoroethylene iyo perfluoropropene. Waxa kale oo loo isticmaali karaa diyaarinta fluorine solfonic acid. sida sunta cayayaanka iyo dareeraha gaarka ah.
Xidhmada, Gaadiidka iyo Kaydinta
1.Vinylidene fluoride (VDF) waa in lagu kaydiyaa haamo leh interlayer kaas oo lagu dallacay milix la qaboojiyey, iyada oo sahayda milixda la qaboojiyey aan jabin.
2.Vinylidene fluoride (VDF) waa mamnuuc in lagu dallaco dhululubada birta ah.Haddii aad u baahan tahay dhululubada birta ee baakadaha, waa inay isticmaashaa dhululubo bir ah oo gaar ah oo laga sameeyay walxaha iska caabinta heerkulka hooseeya.
3. Biraha dhululubada ee lagu shubo fayloraydhka vinylidene (VDF) waa in lagu rakibaa koofiyadaha badbaadada oo si adag loogu xidhxidhay gaadiidka, lagana ilaalinayo dabkaDhululubada birta ah waa in la raro lagana dejiyaa si fudud, iyadoo laga ilaalinayo gariir iyo isku dhac.
