Nrog rau kev nthuav dav ntawm kev thov zog tshiab, nws xav tias Tuam Tshoj lub khw muag khoom capacitor zaj duab xis yuav nkag mus rau lub sijhawm loj hlob siab dua hauv ob peb xyoos tom ntej. Zaj duab xis Polypropylene, cov khoom siv tseem ceeb ntawm cov capacitor zaj duab xis, txuas ntxiv nthuav nws qhov sib txawv ntawm kev muab khoom thiab kev thov vim yog kev nthuav dav sai ntawm kev thov thiab qeeb tso tawm ntawm lub peev xwm tsim khoom. Tsab xov xwm lub lim tiam no yuav saib cov khoom siv tseem ceeb ntawm cov capacitor zaj duab xis - polypropylene zaj duab xis (PP zaj duab xis).

Thaum xyoo 1960s lig, zaj duab xis polypropylene hluav taws xob tau dhau los ua ib qho ntawm peb zaj duab xis hluav taws xob loj vim nws cov yam ntxwv hluav taws xob thiab kev ua haujlwm tshwj xeeb thiab kev ua tau zoo heev, thiab tau siv dav hauv kev lag luam capacitor fais fab. Thaum ntxov xyoo 1980s, kev tsim cov metallized polypropylene zaj duab xis capacitors twb tau pib hauv cov tebchaws tsim kho hauv Tebchaws Europe thiab Asmeskas, thaum Tuam Tshoj tseem nyob rau theem kev txhim kho ntawm metallized polypropylene zaj duab xis capacitors. Tsuas yog los ntawm kev qhia txog metallized polypropylene zaj duab xis capacitor manufacturing technology thiab cov khoom siv tseem ceeb peb tau metallized polypropylene zaj duab xis capacitors hauv qhov tseeb.

Cia peb kawm txog kev siv cov zaj duab xis polypropylene hauv cov capacitors zaj duab xis thiab qee qhov kev qhia luv luv. Cov polypropylene zaj duab xis capacitors yog cov organic zaj duab xis capacitor chav kawm, nws cov khoom nruab nrab yog polypropylene zaj duab xis, electrode muaj hom hlau host thiab hom zaj duab xis hlau, lub hauv paus ntawm lub capacitor yog qhwv nrog epoxy resin lossis encapsulated hauv yas thiab hlau rooj plaub. Lub polypropylene capacitor ua los ntawm cov 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 feem ntau yog tuab dua, tawv dua, thiab muaj lub zog tensile siab dua, thiab tuaj yeem siv rau cov zaj duab xis tsev cog khoom, cov hnab nqa khoom, thiab lwm yam. Polypropylene yog cov polymer tsis muaj tshuaj lom, tsis muaj ntxhiab, tsis muaj saj, dawb milky, crystalline heev nrog qhov ceev ntawm tsuas yog 0. 90-0. 91g / cm³. Nws yog ib qho ntawm cov yas sib dua tshaj plaws muaj. Nws ruaj khov tshwj xeeb rau dej, qhov dej nqus dej hauv dej tsuas yog 0. 01%, qhov hnyav molecular ntawm kwv yees li 80,000-150,000.

Zaj duab xis polypropylene yog cov khoom tseem ceeb ntawm cov capacitors zaj duab xis. Txoj kev tsim cov capacitor zaj duab xis hu ua metallized film, uas yog ua los ntawm lub tshuab nqus tsev vaporizing ib txheej hlau nyias nyias ntawm cov yas zaj duab xis ua electrode. Qhov no tuaj yeem txo qhov ntim ntawm lub peev xwm ntawm lub capacitor, yog li zaj duab xis yooj yim dua los ua cov capacitors me me, muaj peev xwm siab. Cov khoom siv sab saud ntawm zaj duab xis capacitor feem ntau suav nrog cov zaj duab xis puag, cov ntawv ci hlau, hlau, cov ntim sab nraud, thiab lwm yam. Ntawm lawv, zaj duab xis puag yog cov khoom siv raw tseem ceeb, thiab qhov sib txawv ntawm cov khoom siv yuav ua rau cov capacitors zaj duab xis qhia txog kev ua tau zoo sib txawv. Zaj duab xis puag feem ntau muab faib ua polypropylene thiab polyester. Cov zaj duab xis puag tuab dua, qhov siab dua qhov voltage nws tuaj yeem tiv taus, thiab vice versa, qhov qis dua qhov voltage nws tuaj yeem tiv taus. Zaj duab xis puag yog cov zaj duab xis hluav taws xob qib, vim tias dielectric ntawm cov capacitors zaj duab xis yog cov khoom siv raw sab saud tseem ceeb tshaj plaws, uas txiav txim siab qhov ua tau zoo ntawm cov capacitors zaj duab xis thiab nyob 60% -70% ntawm cov nqi khoom siv. Hais txog tus qauv kev ua lag luam, cov tuam txhab tsim khoom Nyij Pooj muaj kev coj ua meej meej hauv cov khoom siv raw rau cov capacitors zaj duab xis siab, nrog Toray, Mitsubishi thiab DuPont yog cov neeg muab khoom zaj duab xis zoo tshaj plaws hauv ntiaj teb.

Cov yeeb yaj kiab polypropylene hluav taws xob rau cov tsheb fais fab tshiab, photovoltaic thiab cua zog feem ntau yog sib sau ua ke ntawm 2 thiab 4 microns, thiab lub peev xwm tsim khoom tau raug txo qis ntau dua ib nrab hauv tib lub sijhawm piv rau 6 txog 8 microns rau cov khoom siv hauv tsev, ua rau muaj kev poob qis ntawm tag nrho cov khoom tsim tawm thiab kev hloov pauv ntawm kev muab khoom thiab kev thov hauv kev ua lag luam. Kev muab cov yeeb yaj kiab polypropylene hluav taws xob yuav raug txwv hauv xyoo tom ntej. Tam sim no, cov khoom siv tseem ceeb ntawm cov yeeb yaj kiab polypropylene hluav taws xob thoob ntiaj teb yog tsim tawm hauv lub teb chaws Yelemees, Nyiv Pooj thiab lwm lub tebchaws, thiab lub voj voog tsim kho ntawm lub peev xwm tshiab yog 24 txog 40 lub hlis. Tsis tas li ntawd, cov kev xav tau kev ua tau zoo ntawm cov yeeb yaj kiab tsheb fais fab tshiab yog siab, thiab tsuas yog ob peb lub tuam txhab muaj peev xwm tswj hwm kev tsim khoom loj ntawm cov yeeb yaj kiab polypropylene hluav taws xob tshiab, yog li thoob ntiaj teb, yuav tsis muaj peev xwm tsim cov yeeb yaj kiab polypropylene tshiab hauv xyoo 2022. Lwm yam kev nqis peev hauv cov kab ntau lawm tab tom sib tham. Yog li ntawd, tej zaum yuav muaj qhov sib txawv loj dua rau tag nrho kev lag luam xyoo tom ntej.
