FA'ATULAGA:
Fa'amatalaga:
O le Poly(vinylidene fluoride) PVDF o se polymer e le o se vaega o le crystalline e iai uiga piezo-, pyro- ma ferroelectric. O se polymer laina e iai uiga tumau o le eletise e fa'asaga tonu i le itu o le filifili molecular. O nei dipoles e mafua mai i le eseesega o le electronegativity i le va o atoms o le hydrogen ma le fluorine e fa'atatau i le carbon. E fa'atatau i tulaga o le fa'agasologa, o le PVDF e iai ni vaega eseese o le crystalline (α,β,γ,δ). O le vaega β o le PVDF o le vaega lea e iai uiga sili ona lelei o le ferroelectric ma le piezoelectric.

Fa'aaogāga
E tete'e le Poly(vinylidene fluoride) i le tele o 'āsi ma alkali ae e osofa'ia e le 'āsi sulfuric 'asu. E mafai ona solo i le dimethylacetamide ae e le solo i ni 'āsi e le tele ni polar. Ua gaosia ni Copolymers i le ethylene, tetrafluoroethylene, chlorotrifluoroethylene ma le hexafluoroethylene. O le mea mulimuli o se elastomer e ta'ua o le Viton po'o le Fluorel.
O le homopolymer e fa'aaogaina o se ufiufi e tete'e atu i vaila'au mo u'amea, mo laina o tane, paipa, ma impellor o pamu. O le elastomeric copolymer fa'atasi ai ma le hexafluoroethylene pe a fa'ama'a'aina i le hexamethylenediamine e fa'aaogaina o se fa'amaufa'ailoga, gasket, 0-mama, paipa, ufiufi ma laina.
E aogā le Poly(vinylidene fluoride) i vali, ata tifaga, ie faamama, laina o mea faigaluega, membrane faamama, vaega o pamu, laina ma valve. E faʻaaogaina foʻi o se mea mo transducers i masini e pei o headphones, microphones ma leo detectors. E taua foʻi mo piezoelectric ma electrostrictive applications. E le gata i lea, e aogā mo laina fagota monofilament e sui ai le nylon monofilament. E galue o se mea e faʻapipiʻi ai masani e faʻaaogaina i le gaosiga o electrodes composite mo maa lithium ion. E galue o se insulator maualuga mo uaea, nanomaterials ma pressure sensors. E faʻaaogaina e fai ai faamama e faʻaaogaina e saunia ai faʻataʻitaʻiga mo le chromatography vai maualuga ma isi metotia faʻataʻitaʻi faʻapitoa.
O mea e ufiufi ai, ata tifaga, ie faamama, ufi o meafaigaluega, membrane faamama, vaega o pamu ma ufi ma valve.
Afifiina ma le Felauaiga
20KG/Palu
E patino i oloa masani ma e mafai ona tilivaina i le vasa ma le ea
Tausia ma teuina
Umi e teu ai: 24 masina mai le aso na gaosia ai i totonu o le afifiina muamua e leʻi tatalaina teuina i se nofoaga malūlū ma mago, ʻaloʻese mai le la saʻo, vai.
Faleteuoloa e fa'amamago i le ea, fa'amago i le vevela maualalo, Vavae'ese mai mea e fa'aola ai le ea, 'asi.
