Polyvinylidene fluoride orpolyvinylidene difluoride (PVDF) inonzi semi-crystalline thermoplastic fluoropolymer.Iri nyore kunyunguduka-inogadziriswa uye inogona kugadzirwa kuita zvikamu nejekiseni uye nekumanikidza kuumba.Inobatanidza simba rakakwirira remagetsi nekugadzirisa kwakanaka.PVDFinowanzo shandiswa mumakemikari ekugadzira michina yakadai sepombi, mavharuvhu, pombi, machubhu uye fittings.Mushonga wayo wemakemikari ndeye (C2H2F2) n.PVDF ipurasitiki yakakosha inoshandiswa mumashandisirwo anoda kuchena kwepamusoro, pamwe nekuramba kune zvinonyungudutsa, asidhi nemahydrocarbon.PVDF ine low density 1.78 g/cm3 tichienzanisa nemamwe mafluoropolymers, senge polytetrafluoroethylene.
Inowanikwa mumhando yezvigadzirwa zvepombi, shiti, tubing, mafirimu, ndiro uye insulator yeprimiyamu waya.Inogona kubaiwa, kuumbwa kana kusungirirwa uye inowanzoshandiswa mumakemikari, semiconductor, maindasitiri ekurapa uye ekudzivirira, pamwe nemulithium-ion mabhatiri.Inowanikwawo se across-linked yakavharwa-sero furo, inoshandiswa zvakanyanya mukubhururuka nendege uye aerospace application, uye seyekunze 3D printer filament.Inogona zvakare kushandiswa mukudzokororwa kusangana nezvigadzirwa zvekudya, sezvo iri FDA-inoenderana uye isiri-chepfu pazasi kwayo tembiricha yekushatisa.
Mumakore achangopfuura, pakave nekufarira kukuru kwakaratidzwa mu polymer Polyvinylidene Fluoride (PVDF).Kufarira kwayakagamuchira nekuti inoratidza yakasimba kwazvo piezoelectric zvivakwa kana zvichienzaniswa nechero imwe yepolymer yekutengesa.Iyo polymer inoshandiswa zvakanyanya mumhando yepamusoro tech application senge makemikari process zvishandiso, zvemagetsi nemagetsi, hunyanzvi uye zvine chekuita nesimba mashandisiro.Asi, chii chinoita kuti PVDF ive yepurasitiki yepamusoro muzvikamu zvakati wandei?Verenga kuti uzive zvakawanda.
PVDF (PVF2 kana Polyvinylidene fluoride kana polyvinylidene difluoride) ndeye semi-crystalline, yakakwirira kuchena thermoplastic fluoropolymer.Iine tembiricha yebasa inosvika 150°C, PVDF inoratidza musanganiswa wakanaka wezvivakwa zvakaita se:
- Kusarudzika kwemakemikari kuramba
- High mechanical simba
- Piezoelectric uye pyroelectric zvivakwa
- Zvakare zvakanaka processability
Kusanyungudika kwayo kwakanyanya uye zvivakwa zvemagetsi zvinobva kune polarity yekuchinjanisa CH2 uye CF2 mapoka pane polymer cheni.
PVDF inonyungudika nyore nyore uye inogona kugadzirwa kuita zvidimbu nejekiseni uye nekumanikidza kuumba.Nekuda kweizvozvo, inowanzoshandiswa mumakemikari ekugadzira michina yakadai semapombi, mavharuvhu, mapaipi, machubhu uye fittings;sensors uye actuators nezvimwe.
Iyo ine akawanda emagetsi maapplication, kunyanya sejaketi zvinhu zveplenum-yakatemerwa tambo inoshandiswa muzwi nemavhidhiyo zvishandiso uye maalarm system.Iyo yakaderera murazvo unopararira uye chizvarwa cheutsi chePVDF chinhu chakakosha mukushandisa uku.
PVDF iri kuwana kugamuchirwa sebhainda remacathodes uye anode mumabhatiri e-lithium-ion, uye separator yebhatiri mu lithium-ion polymer systems.
Kusimukira mashandisirwo ePVDF anosanganisira mafuta cell membranes, uye zvikamu zvemukati wendege uye hofisi otomatiki michina.
Nekuda kwemusanganiswa wayo wakanakisa wezvivakwa uye kugadzirisa, PVDF yave yakakura vhoriyamu yefluoropolymers mushure mePTFE.
PVDF inowanikwa mune zvekutengesa muhuwandu hwakasiyana hwekunyungudika kuyerera uye neakasiyana ekuwedzera kuwedzera kugadzirisa kana kupedzisa kushandisa zvivakwa.
Yedu epurasitiki recycling muchina taigona kushandisa sikuruu nedhiramu kugadzira nekudzokorodza PVDF. The Screw we adopt the C267 alloy and the barrel adopt the Ni alloy.Iyo yekudzokorodza uye pelletizing system ichashandisa iyostrand pelletizing kugadzirisa zvinhu.
