Introduction to PI Film
PI (polyimide) zaj duab xis yog tam sim no siab tshaj -cov ntaub ntawv insulating zaj duab xis nyob hauv lub ntiaj teb. Nws boasts zoo heev txhua yam thiab hluav taws xob zog, tshuaj stability, thiab tshwj xeeb kuj rau hluav taws xob, kub kub, thiab kub tsis tshua muaj (xws li ntawm -269℃mus rau +400 degree).
Kev faib tawm ntawm PI Zaj duab xis los ntawm Cov Txheej Txheem Ntau Lawm:
1) Txoj kev impregnation
Kev nqis peev tsawg tsawg, tab sis cov nqi tsim khoom siab thiab cov khoom siv tsawg.
2) Cast film
Cov nqi tsim khoom tsawg; tsim cov yeeb yaj kiab zoo nrog cov khoom zoo.
3) Biaxially stretched zaj duab xis
Kev nqis peev ntau dua, tab sis muaj lub cev zoo, hluav taws xob, thiab thermal zog.
PI Film Applications
PI zaj duab xis yog ib qho ntawm cov khoom lag luam tshaj plaws polyimide thiab feem ntau yog siv rau Class H lossis Class C rwb thaiv tsev. Vim nws cov khoom zoo heev -xws li roj thiab kub tsis kam thiab tsis tshua muaj dielectric poob -polyimide daim kab xev hu ua "Golden daim kab xev." Nws ua hauj lwm raws li cov khoom siv rau cable rwb thaiv tsev, thermal rwb thaiv tsev, hluav taws xob shielding, thiab cov ntaub ntawv kaw lus xov xwm. Nws daim ntawv thov hauv kev lag luam hloov pauv hloov pauv (FPC) kev lag luam, tshwj xeeb, tau coj mus rau kev siv dav hauv aerospace, tub rog, kev sib txuas lus ntawm tes, laptops, khoos phis tawj, PDAs, koob yees duab digital, thiab kev ntsuas hluav taws xob. Nws tau dhau los ua cov khoom siv tsis raug, tseem ceeb hauv lub zog, cov khoom siv hluav taws xob, microelectronics, thiab precision machinery industries.
(Circuit boards)
PI zaj duab xis yog dav siv hauv microelectronics, nrog rau cov teeb pom kev zoo OLED, nyias- zaj duab xis hnub ci, pob tshab electromagnetic radiation shielding films, RF Circuit Court boards, thiab kov cov ntxaij vab tshaus. (OLED zaub)
PI Film Market Txheej txheem cej luam
PI zaj duab xis yog hu ua "Golden Tape," nrog cov nqi lag luam xws li RMB 6 lab txog 30 lab ib tuj; tshwj xeeb, biaxially stretched electronic- qib zaj duab xis muag rau ntau tshaj RMB 10 lab ib tuj. Kev thov hauv tsev tau loj hlob sai, tab sis kev ua lag luam vam khom ntau ntawm kev xa khoom thiab ntsib cov khoom lag luam tseem ceeb -xav tau qhov sib txawv. Kev lag luam muaj kev cuam tshuam loj heev rau kev nkag, thiab cov khoom siv yog cov concentrated heev. Vim yog qhov nyuaj ntawm kev sib txuas ntawm polyimide thiab cov teeb meem cuam tshuam hauv kev ua cov khoom lag luam qis, cov khoom siv thoob ntiaj teb ntawm polyimide yog concentrated ntawm ob peb lub tuam txhab (DuPont ntawm Teb Chaws Asmeskas, Ube Industries thiab Kaneka ntawm Nyiv, thiab SK Kolon ntawm South Kauslim).
