PI (polyimide) siab- daim kab xev ntsuas kub yog ua los ntawm polyimide zaj duab xis- tsim los ntawm kev sib txuas ntawm pyromellitic dianhydride thiab diaminodiphenyl ether hauv cov kuab tshuaj muaj zog heev tom qab imidization. Nws yog coated ntawm ib los yog ob sab nrog silicone los yog silicone -dawb nplaum los ua daim kab xev tiav. Feem ntau nyob ib ncig ntawm 0.045mm tuab, nws muaj ntau yam xim xws li amber, dub, thiab ntsuab. Nws muaj lub zog adhesion ntawm kwv yees li 450-700g ib 25 hli, qhov kub tsis kam ntawm kwv yees li -10℃txog 290 degree, thiab lub zog tev ntawm li 3-6N. Nws yog tus cwj pwm los ntawm qhov kub thiab txias tsis kam, hluav taws xob rwb thaiv tsev, hluav taws xob tiv thaiv, thiab tiv thaiv acids thiab alkalis. Kehongjian PI daim kab xev tawm tsis muaj cov nplaum seem thaum tshem tawm thiab ua rau tsis muaj kev puas tsuaj rau cov khoom siv hluav taws xob tiv thaiv.
PI siab- daim kab xev ntsuas kub feem ntau yog siv rau cov khoom siv hluav taws xob uas xav tau kev tiv thaiv thaum cov txheej txheem uas muaj qhov kub ntawm 260℃; nws yog ib qho ntawm cov cua sov tshaj plaws - tiv taus hom siab - kub tapes muaj. Cov ntawv thov feem ntau suav nrog kev npog "cov ntiv tes kub" thaum lub sijhawm nthwv dej lossis rov ua dua ntawm PCBs, nrog rau kev tiv thaiv thaum lub lauj kaub thiab kub - huab cua leveling txheej txheem. Nws kuj yog siv rau rwb thaiv tsev nyob rau hauv lithium roj teeb thiab motors, ntug wrapping rau roj teeb hlwb, thiab binding transformer coils; Nyob rau hauv cov ntaub ntawv no, daim kab xev yuav tsum tau muab cia rau hauv ib tug qhuav, chav tsev - qhov kub thiab txias thiab kom deb ntawm kev sib cuag nrog lwm yam kua.
Thaum PI siab- daim kab xev kub kuj tseem siv tau rau kev tiv thaiv ib ntus thaum cov txheej txheem semiconductor xws li pleev xim thiab electroplating, PET siab - daim kab xev kub feem ntau txaus rau cov haujlwm no thiab los ntawm tus nqi qis dua. Yog li ntawd, qhov tsim nyog tshaj qhov siab -tej kab xev kub yuav tsum raug xaiv raws li qhov chaw thov tshwj xeeb.
