Lintho tse bonahalang tsa PVDF ke eng?
Polyvinylidene Fluoride (PVDF) ke thepa e sebetsang hantle haholo e sebelisoang haholo indastering ea lik'hemik'hale le ea tlhahiso, 'me e ratoa ka lebaka la khanyetso ea eona e ntle ea lik'hemik'hale, thepa ea motlakase le matla a mochini. Sehloohong sena, re tla sekaseka ka botlalo hore na PVDF ke eng, thepa ea eona, lits'ebetso le ts'ebetso ea tlhahiso ho u thusa ho utloisisa hamolemo melemo ea thepa ena.
Taba ea pele, litšobotsi tsa mantlha tsa PVDF
PVDF ke semi-crystalline thermoplastic fluoropolymer, haholo-holo polymerised ho tloha vinylidene fluoride (VDF) monomer. Ka lebaka la matla a phahameng a electronegativity ea athomo ea fluorine le matla a bond ea CF, PVDF e bonts'a thepa e latelang:

Khanyetso ea lik'hemik'hale: PVDF e hanyetsana haholo le li-acids tse ngata, alkalis, matsoai le metsoako e hlapollang, e etsang hore e tsitse le ho mamella ho bola indastering ea lik'hemik'hale ha nako e ntse e ea.

Matla a Mechini: PVDF e na le matla a matla a ho tsitlella le ho hanyetsa tšusumetso, e e nolofalletsang ho boloka botsitso ba eona maemong a thata.

Thepa ea Motlakase: Ka lebaka la thepa ea eona e tlaase ea dielectric kamehla le e phahameng ea insulating, PVDF e sebelisoa haholo libakeng tsa motlakase le tsa elektroniki, haholo-holo e le lisebelisoa tse sireletsang lithapo le likhoele.

Thermal stability: PVDF e na le botsitso bo botle ba mocheso 'me e ka sebelisoa mefuteng e mengata ea mocheso,' me hangata e ka boloka litšobotsi tsa eona tsa 'mele ho mocheso oa -40°C ho isa ho 150°C.

Ea bobeli, mokhoa oa tlhahiso ea PVDF
Tlhahiso ea PVDF e fihlelleha haholo ka ho etsa polymerisation ea mahala, hangata ka tharollo ea polymerisation kapa suspension polymerisation. Ts'ebetsong ea polymerization, li-monomers tsa VDF li entsoe ka polymer ho PVDF polymer tlasa maemo a itseng a karabelo. Ka mor'a moo, ka letoto la mekhoa ea phekolo ka mor'a ho phekoloa, ho kenyelletsa ho hloekisoa, extrusion le granulation, sebopeho sa ho qetela sa lihlahisoa tsa PVDF tse nang le thepa e khethehileng ea 'mele.
Ea boraro, libaka tse kholo tsa ts'ebeliso ea PVDF
PVDF e sebelisitsoe haholo liindastering tse ngata ka lebaka la ts'ebetso ea eona e ntle haholo:

Indasteri ea lik'hemik'hale: PVDF e atisa ho sebelisoa ha ho etsoa lik'hemik'hale tse sa tšoaneng, liphaephe le li-valve, haholo-holo ketsahalong e amanang le lik'hemik'hale tse senyang.

Indasteri ea kaho: PVDF e sebelisoa ha ho etsoa liphahlo tse sebetsang hantle haholo, tse kang tse entsoeng ka fluorocarbon, tse sebelisetsoang ho sireletsa mabota a ka ntle a meaho, 'me li khona ho boloka botle ba meaho nako e telele ka lebaka la mahlaseli a eona a mahlaseli a kotsi le botsofali.

Indasteri ea elektronike le ea motlakase: PVDF e sebelisoa haholo ha ho etsoa lithapo, lihokelo le li-diaphragm tsa betri ea lithium ka lebaka la ts'ebetso ea eona e ntle ea motlakase le ho hanyetsa mocheso.

Indasteri ea ho hloekisa metsi: Lisebelisoa tsa membrane tsa PVDF li sebelisoa tšimong ea ho hloekisa metsi, haholo-holo ho li-membrane tsa ultrafiltration le nanofiltration, tse ratoang ka lebaka la lik'hemik'hale tse phahameng tsa lik'hemik'hale le ho nepahala ho phahameng ho hloekisa.

Ea bone, litebello tsa 'maraka le liphephetso tsa PVDF
Ka ho potlakisa ha indasteri le ho eketseha ha tlhokahalo ea lisebelisoa tse phahameng, 'maraka oa PVDF o ntse o hōla ka potlako.Theko e phahameng ea tlhahiso le ho rarahana ha mokhoa oa tlhahiso ea PVDF e etsa hore theko ea eona ea' maraka e be theko e boima haholo. Tšebeliso ea PVDF e boetse e tobane le mathata a itseng ka lebaka la litaba tsa tikoloho tse amanang le fluoride. Ka hona, ho ntlafatsa ts'ebetso ea tlhahiso le ho fokotsa tšusumetso ea tikoloho ea PVDF e tla ba senotlolo sa nts'etsopele ea nako e tlang.
Kakaretso
Lintho tse bonahalang tsa PVDF ke eng? Ka tlhahlobo e kaholimo, re ka bona hore PVDF ke sesebelisoa sa fluoropolymer se sebetsang hantle se nang le menyetla e mengata ea ts'ebeliso. Ho hanyetsa lik'hemik'hale tse babatsehang, matla a mochine, thepa ea motlakase le botsitso ba mocheso li etsa hore e be le karolo ea bohlokoa masimong a mangata. Ka ntlafatso ea litlhoko tsa ts'ireletso ea tikoloho, tlhahiso le ts'ebeliso ea PVDF le eona e tla tobana le mathata le menyetla e mecha. Ho utloisisa le ho tseba thepa le ts'ebeliso ea PVDF ho ka fana ka ts'ehetso ea bohlokoa bakeng sa boqapi le nts'etsopele ea liindasteri tse amanang.
