Kedu ihe bụ PVDF ihe?
Polyvinylidene Fluoride (PVDF) bụ ihe na-arụ ọrụ dị elu nke a na-ejikarị eme ihe na ụlọ ọrụ kemịkalụ na ụlọ ọrụ mmepụta ihe, a na-akwado ya maka nguzogide kemịkalụ ya dị mma, ihe ọkụ eletrik na ike ọrụ. N'isiokwu a, anyị ga-enyocha nke ọma ihe PVDF bụ, ihe onwunwe ya, ngwa na mmepụta usoro iji nyere gị aka ịghọta uru nke ihe a.
Nke mbụ, njirimara ndị bụ isi nke PVDF
PVDF bụ ọkara kristal thermoplastic fluoropolymer, tumadi polymerized site na vinylidene fluoride (VDF) monomer. N'ihi nnukwu electronegativity nke atom fluorine na ike nke njikọ CF, PVDF na-egosipụta njirimara ndị a:

Mgbochi kemịkalụ: PVDF na-eguzogide ọgwụ na ọtụtụ acid, alkalis, salts and solvents, nke na-eme ka ọ kwụsie ike ma na-eguzogide corrosion na ụlọ ọrụ kemịkalụ ka oge na-aga.

Ike Mechanical: PVDF nwere ezigbo ike nkwụsi ike yana nguzogide mmetụta, na-enyere ya aka ịnọgide na-eguzosi ike n'ezi ihe nhazi ya na gburugburu ebe siri ike.

Ngwongwo eletriki: N'ihi dielectric dielectric ya dị ala na ihe mkpuchi dị elu, a na-eji PVDF eme ihe na eletrik eletrik na eletriki eletrik, karịsịa dị ka ihe mkpuchi mkpuchi maka wires na eriri.

Nkwụsi ike nke okpomọkụ: PVDF nwere ezigbo nkwụsi ike na-ekpo ọkụ ma nwee ike iji ya mee ihe n'ụdị okpomọkụ dị iche iche, ma nwee ike na-edobe ihe onwunwe ya na okpomọkụ nke -40 ° C ruo 150 ° C.

Nke abụọ, usoro mmepụta nke PVDF
A na-enweta mmepụta nke PVDF site na polymerisation free radical, na-abụkarị site na polymerisation ngwọta ma ọ bụ nkwusioru polymerisation. Na usoro polymerisation, VDF monomers na-polymerized n'ime PVDF polymer n'okpuru ọnọdụ mmeghachi omume kpọmkwem. Mgbe nke ahụ gasịrị, site na usoro ọgwụgwọ ọgwụgwọ, gụnyere ịdị ọcha, extrusion na granulation, nhazi ikpeazụ nke ngwaahịa PVDF nwere njirimara anụ ahụ.
Nke atọ, mpaghara ngwa ngwa nke PVDF
A na-eji PVDF eme ihe n'ọtụtụ ụlọ ọrụ n'ihi ọmarịcha arụmọrụ ya:

Ụlọ ọrụ kemịkalụ: A na-ejikarị PVDF eme ihe dị iche iche nke kemịkalụ, ọkpọkọ na valvụ, karịsịa n'oge metụtara kemịkal na-emebi emebi.

Ụlọ ọrụ ihe owuwu: A na-eji PVDF na-emepụta ihe mkpuchi dị elu, dị ka mkpuchi fluorocarbon, nke a na-eji echebe mgbidi dị n'èzí nke ụlọ, ma nwee ike ịnọgide na-enwe mma nke ụlọ ahụ ruo ogologo oge n'ihi ihe ndị na-eguzogide UV na ịka nká.

Ụlọ ọrụ eletrọnịkị na eletrik: A na-eji PVDF eme ihe n'ọtụtụ ebe na mmepụta nke eriri, njikọ na batrị lithium diaphragms n'ihi mkpuchi ọkụ eletrik dị mma na nkwụsị ọkụ.

Ụlọ ọrụ ọgwụgwọ mmiri: A na-eji ihe mkpuchi akpụkpọ anụ PVDF mee ihe n'ọhịa nke ọgwụgwọ mmiri, karịsịa na ultrafiltration na nanofiltration membranes, nke a na-ahọrọ maka nguzogide kemịkalụ dị elu na nzacha dị elu.

Nke anọ, atụmanya ahịa na ihe ịma aka nke PVDF
Site na mmụba nke mmepụta mmepụta ihe na mmụba nke ihe ndị na-arụ ọrụ dị elu, ahịa PVDF na-eto ngwa ngwa. Ọnụ ahịa mmepụta ihe dị elu na mgbagwoju anya nke usoro mmepụta nke PVDF na-eme ka ọnụ ahịa ahịa ya dịkwuo ọnụ. Ngwa nke PVDF na-echekwa ihe ịma aka ụfọdụ ihu n'ihi nsogbu gburugburu ebe obibi metụtara fluoride. Ya mere, ịkwalite usoro mmepụta na ibelata mmetụta gburugburu ebe obibi nke PVDF ga-abụ isi ihe maka mmepe n'ọdịnihu.
Nchịkọta
Kedu ihe bụ PVDF ihe? Site na nyocha nke dị n'elu, anyị nwere ike ịhụ na PVDF bụ ihe fluoropolymer na-arụ ọrụ dị elu nke nwere atụmanya ngwa dị iche iche. Nguzogide kemịkalụ ya dị mma, ike igwe, ihe ọkụ eletrik na nkwụsi ike ọkụ na-eme ka ọ rụọ ọrụ dị mkpa n'ọtụtụ mpaghara. Site na nkwalite nke ihe nchebe gburugburu ebe obibi chọrọ, mmepụta na ntinye nke PVDF ga-echekwa ihe ịma aka na ohere ọhụrụ ihu. Ịghọta na ịmụta akụrụngwa na ngwa nke PVDF nwere ike inye nkwado dị mkpa maka mmepụta ọhụrụ na mmepe nke ụlọ ọrụ ndị metụtara ya.
