Nrog rau kev nthuav dav ntxiv ntawm kev thov lub zog tshiab, nws xav tias Tuam Tshoj cov yeeb yaj kiab capacitor kev lag luam yuav nkag mus rau lub sijhawm loj hlob ntxiv nyob rau ob peb xyoos tom ntej no.Polypropylene zaj duab xis, cov khoom tseem ceeb ntawm zaj duab xis capacitors, txuas ntxiv nthuav dav nws cov khoom siv thiab kev xav tau sib txawv vim qhov kev nthuav dav sai ntawm kev thov thiab kev tso tawm qeeb ntawm lub peev xwm ntau lawm.Lub lim tiam no tsab xov xwm yuav saib cov khoom tseem ceeb ntawm zaj duab xis capacitors- polypropylene zaj duab xis (PP zaj duab xis).

Nyob rau xyoo 1960s, polypropylene hluav taws xob zaj duab xis tau los ua ib qho ntawm peb lub tshuab hluav taws xob loj vim nws cov khoom siv hluav taws xob tshwj xeeb thiab kev ua haujlwm thiab cov nqi zoo heev, thiab tau siv dav hauv kev lag luam hluav taws xob capacitor.Nyob rau xyoo 1980s, kev tsim cov metallized polypropylene zaj duab xis capacitors twb tau pib nyob rau hauv cov teb chaws tsim nyob rau hauv cov teb chaws Europe thiab America, thaum Tuam Tshoj tseem nyob rau hauv txoj kev loj hlob ntawm metallized polypropylene zaj duab xis capacitors.Tsuas yog los ntawm kev taw qhia ntawm metallized polypropylene zaj duab xis capacitor manufacturing technology thiab cov khoom tseem ceeb peb puas tau metallized polypropylene zaj duab xis capacitors hauv qhov tseeb.

Cia peb paub txog kev siv cov yeeb yaj kiab polypropylene hauv zaj duab xis capacitors thiab qee qhov kev qhia luv luv.Polypropylene zaj duab xis capacitors belongs rau cov organic zaj duab xis capacitor chav kawm, nws nruab nrab yog polypropylene zaj duab xis, electrode muaj hlau host hom thiab hlau zaj duab xis hom, cov tub ntxhais ntawm lub capacitor yog qhwv nrog epoxy resin los yog encapsulated nyob rau hauv yas thiab hlau rooj plaub.Lub polypropylene capacitor ua nrog hlau zaj duab xis electrode hu ua metallized polypropylene zaj duab xis capacitor, uas feem ntau hu ua zaj duab xis capacitor.Polypropylene zaj duab xis yog cov thermoplastic resin ua los ntawm polymerizing propylene.Nws yog feem ntau thicker, tougher, thiab muaj zog tensile ntau dua, thiab yuav siv tau rau tsev xog paj zaj duab xis, load-bearing hnab, thiab lwm yam Polypropylene yog ib tug uas tsis yog-tshuaj lom, tsw, tasteless, milky dawb, heev crystalline polymer nrog ib tug ntom ntawm xwb. 0.90-0.91g/cm3 ua.Nws yog ib lub lightest ntau yam ntawm tag nrho cov yas muaj.Nws yog qhov tshwj xeeb ruaj khov rau dej, qhov nqus dej hauv dej tsuas yog 0. 01%, molecular hnyav li ntawm 80,000-150,000.

Polypropylene zaj duab xis yog cov khoom tseem ceeb ntawm zaj duab xis capacitors.Cov txheej txheem tsim cov yeeb yaj kiab capacitor yog hu ua zaj duab xis metallized, uas yog tsim los ntawm lub tshuab nqus tsev vaporizing ib txheej nyias ntawm cov hlau ntawm yas zaj duab xis li electrode.Qhov no tuaj yeem txo qhov ntim ntawm lub capacitor unit muaj peev xwm, yog li cov zaj duab xis yog yooj yim dua los ua me me, siab capacitors.Lub upstream ntawm zaj duab xis capacitor feem ntau suav nrog cov zaj duab xis hauv paus, hlau ntawv, hlau, txheej ntim, thiab lwm yam. Ntawm lawv, lub hauv paus zaj duab xis yog cov khoom siv raw, thiab qhov sib txawv ntawm cov khoom yuav ua rau cov yeeb yaj kiab capacitors muaj kev cuam tshuam kev sib txawv.Lub hauv paus zaj duab xis feem ntau muab faib ua polypropylene thiab polyester.Lub thicker lub hauv paus zaj duab xis yog, qhov siab dua qhov voltage nws tuaj yeem tiv taus, thiab vice versa, qhov qis dua qhov voltage nws tuaj yeem tiv taus.Lub hauv paus zaj duab xis yog cov khoom siv hluav taws xob qib hluav taws xob, vim tias cov dielectric ntawm cov yeeb yaj kiab capacitors yog cov khoom siv tseem ceeb tshaj plaws, uas txiav txim siab qhov ua tau zoo ntawm cov yeeb yaj kiab capacitors thiab occupies 60% -70% ntawm cov khoom siv.Nyob rau hauv cov nqe lus ntawm kev ua lag luam qauv, Japanese manufacturers muaj ib tug ntshiab txhuas nyob rau hauv cov ntaub ntawv raw rau high-end zaj duab xis capacitors, nrog Toray, Mitsubishi thiab DuPont yog lub ntiaj teb no sab saum toj zoo puag zaj duab xis lwm tus neeg.

Hluav taws xob polypropylene zaj duab xis rau lub zog tshiab tsheb, photovoltaic thiab cua zog yog feem ntau yog nyob nruab nrab ntawm 2 thiab 4 microns, thiab lub peev xwm tsim tau raug txo los ntawm ntau tshaj ib nrab ntawm tib lub sij hawm piv nrog 6 mus rau 8 microns rau cov khoom siv hauv tsev, uas ua rau nyob rau hauv ib qho kev poob qis hauv tag nrho cov kev tsim khoom thiab kev thim rov qab ntawm cov khoom lag luam thiab kev xav tau.Cov khoom siv hluav taws xob polypropylene zaj duab xis yuav raug txwv rau xyoo tom ntej.Tam sim no, cov cuab yeej tseem ceeb ntawm lub ntiaj teb hluav taws xob polypropylene zaj duab xis yog tsim nyob rau hauv lub teb chaws Yelemees, Nyiv thiab lwm lub teb chaws, thiab kev tsim kho lub voj voog ntawm lub peev xwm tshiab yog 24 mus rau 40 lub hlis.Tsis tas li ntawd, qhov kev ua tau zoo ntawm lub zog tshiab tsheb cov yeeb yaj kiab yog siab, thiab tsuas yog ob peb lub tuam txhab muaj peev xwm ua kom ruaj khov ntawm cov khoom siv hluav taws xob tshiab hluav taws xob polypropylene zaj duab xis, yog li thoob ntiaj teb, yuav tsis muaj cov khoom siv polypropylene tshiab hauv xyoo 2022. Lwm cov peev hauv cov kab ntau lawm yog nyob rau hauv kev sib tham.Yog li ntawd, tej zaum yuav muaj qhov sib txawv loj dua rau tag nrho kev lag luam xyoo tom ntej.
