Chechitatu, kukosha kwekutanga kwePVDF
(1) michina yemakanika
PVDF ine yakanakisa manhamba. Kuenzaniswa nePerfluerocarbon Polymers Polyform Play (kureva kudzikisira kwakakura (kureva kudzikisira kupokana) kuri nani, hupenyu hwekudzokororwa kwenguva refu, uye kurwisa kwakakura kunovandudzika. Simba reMuchina rakanyanya kuvandudzwa zvakanyanya nekurapa. Kuzadza madiki madiki emabhawa egirazi kana carbon fiber kunogona kunatsiridza simba re base polymer.pvdf michina yezvivakwa ndizvo zvinotevera.
PVDF (PolyVinylidene Fluoride) ine zvinhu zvakanakisa zvekushandisa, uye zvimedu zvemakhinji zvimedu zvevakaringana zvinhu zvinotevera:
Simba reSimba: Iyo Simba rePVDF riri kusvika pa50pa, kanokwana kaviri idzo yePTFE (PolytetraFluorohyle) 1.
Tensile Modulus: Pane tensile chiyero che5mm / min, iyo tensile modulus yePVDF is 2280mpa2.
Tensile Yava Simba: Pamuro weCendele wezana 50mm / min, iyo tensile godil will simba rePVDF ndeye 59mpa2.
Elongation at break: At a tensile rate of 50mm/min, the elongation at break of PVDF is 60%2.
Simba rinoshanduka-shanduka: Simba rinosindimara rePVDF riri pakati pemakumi mana nemakumi matanhatu emamita.
Flexural Mowelus yeElasticity: Iyo Flexural Mowelus yePVDF iri pakati pe1.4 uye 1.8 GPA3.
Kudzvinyirira Simba: Iyo yekumanikidza simba rePVDF iri pakati pe69 uye 103 MPA3.
Chinja simba resimba: Iyo impact simba rePVDF is 211J-m-¹3.

(2) zvivakwa zvemagetsi
Izvo zvinokoshesa zvemagetsi zvemagetsi zvePVDF HOOMOPELYME Pasina kana kusarudzika zvakanyorwa patafura Zvemafungidziro ayo akarapwa pasi pemamiriro ezvinhu akasiyana-siyana kuWestments munda
Iyo yakasarudzika dielectric nzvimbo yePVDF uye iyo Homogeneous polycrystalline phenomenon inopa iyi polymer yakakwira piezoelectric uye thermoelectric chiitiko. Ukama pakati peiyo ferroelectric pvdf, kusanganisira piezoelectric neThezoelectric zvivakwa, uye zvimwe zvivakwa zvemagetsi zvakanyatso kukurukurwa munongedzo. Iyo yakakwira dielectric nguva dzose yakawanikwa uye iyo yakaoma homogeneous polycrystalline phenomena neyekuita zvinhu zvinowonekwa neyezvimisikidzwa kunyange nyungudika. Kune rimwe divi, PVDF inogona kunyungudika nenzira yeradiforquency kana electrolyte kupisa, uye chimiro ichi chinoshandiswa mune mamwe maitiro kana kubatana. Yakakwira-simba irradiation crradiation-link pvdf, nekudaro inowedzera simba rayo rechaneti. Ichi chivakwa zvakare chakasarudzika pakati pePolydoleFin Polymers, sevamwe polymers degrade kana ichivhurwa kune yakakwirira simba kurira.
(3) makemikari zvivakwa
PVDF zvakare ine zvinhu zvakanakisa zvemakemikari uye zvinodzivisa kune yakawanda-inormactic acids, maLalogent uye exidizing vamiriri vechigadziri, pamwe nekunyanyisa mishonga uye tomatic makomputa. Nekudaro, zvigadziko zvine simba, maAntes, esters ne ketoni zvinogona kukonzera pvdf kuti uzvipfeke, zvinyoro-nyoro kana kutopfenyura zvichienderana nemamiriro ezvinhu. Vamwe vagadziri uye ketoni vanogona kushandiswa seCo-sol sol soles kuti vanyungure pvdf. Sistimu yakadaro inobvumira iyo yakanyungudutswa ichivhiringidza kunyungudika sezvo tembiricha inosimuka, zvichikonzera kuomesa kwakanaka.
PVDF ndeimwe yemashoma emwenje-crystalline polymers inoenderana nevamwe polymers, kunyanya acrylic uye methacrylic resins. Iyo Crystalline fomu, zvivakwa uye kuita kwevanoita mapuranga akasiyana siyana vanovimba nechimiro uye kuumbwa kwevakadzvanywa polymers, pamwe nekuumbwa kwePVDF. Semuenzaniso, ethyl polyacrylate haina kunyatsogona nyokisi yePVDF, nepopepropyl polwacrylate uye maineni ayo haana. Paunenge uchisarudza mutambo, zvakakosha kuve neyakaomesesa dipole mhedzisiro yekuwana iyo PVDF, nepo polyvinyl fluoride haina kuwirirana nePolyvinylidene Fluoride.
