BPADA CAS 38103-06-9 yog dab tsi?

4,4'-(4,4'-ISOPROPYLIDENEDIPHENOXY)BIS(PHTHALIC ANHYDRIDE) (BPADA) yog ib qho polyetherimide monomer uas tau npaj tseg thiab yog ib hom fusible polyimide. 4,4'-(4,4'-ISOPROPYLIDENEDIPHENOXY)BIS(PHTHALIC ANHYDRIDE) tsis yog tsuas yog khaws cia tag nrho cov khoom zoo heev ntawm polyimide xwb tab sis kuj muaj kev ua haujlwm ntawm cov yas yas dav dav. Ntxiv mus, 4,4'-(4,4'-ISOPROPYLIDENEDIPHENOXY)BIS(PHTHALIC ANHYDRIDE) pheej yig thiab tsim nyog rau kev npaj cov khoom nyias-phab ntsa thiab cov khoom lag luam nyuaj.

Daim Ntawv Thov

1. Ua cov khoom siv polyimide (PI) uas siv dav dav

Qhov no yog qhov kev siv BPADA feem ntau thiab tseem ceeb. BPADA yog polycondensed nrog cov diamine monomers xws li 4,4'-diaminodiphenyl ether (ODA) los tsim polyimide uas sib xyaw "kev tiv taus cua sov thiab yooj yim ua tiav". Hom khoom PI no, vim muaj cov ether bonds thiab isopropyl pawg hauv nws cov qauv molecular, khaws cia qhov kub siab tiv taus ntawm PI (kub ntev 180-220 ℃). BPADA kuj yooj yim dua los ua cov yeeb yaj kiab, phaj, thiab lwm yam dua li PI ib txwm muaj, thiab feem ntau siv rau hauv:

1) Cov khoom siv rwb thaiv tsev yooj yim hauv kev siv hluav taws xob: Zaj duab xis puag thiab zaj duab xis npog rau kev ua cov laug cam luam tawm yooj ywm (FPC), nrog rau cov ntawv rwb thaiv tsev tiv taus kub siab / cov xim pleev xim rwb thaiv tsev rau cov cav thiab cov hloov pauv, kom ua tau raws li "miniaturization + kub tsis kam" cov kev xav tau ntawm cov khoom siv hluav taws xob, xws li kev tiv thaiv rwb thaiv tsev sab hauv rau cov khoom siv hluav taws xob thiab cov cav lag luam.

2) Cov khoom siv tiv taus kub siab rau kev lag luam dav dav: Ua rau hauv PI phaj thiab cov raj, lawv siv rau cov brackets tiv taus kub siab nyob ib puag ncig lub cav tsheb thiab cov khoom siv hauv tsev uas tiv taus kub (xws li qhov cub thiab qhov cub microwave). Lawv tuaj yeem tiv taus kub siab tshaj 150 ℃ ntev, thiab tiv taus kev laus thiab tawg.

2. Hloov cov resins ib txwm muaj los txhim kho kev ua tau zoo

Hauv kev hloov kho cov roj hmab ib txwm muaj, BPADA, ua "monomer tiv taus cua sov", feem ntau yog siv los ua kom zoo dua qhov kev ua tau zoo ntawm epoxy resins thiab phenolic resins thiab nthuav lawv cov xwm txheej siv:

1) Kev hloov kho epoxy resin: Thaum sib xyaw nrog cov epoxy resin, BPADA ua rau cov resin tiv taus kub siab dua (ua rau cov resin kho tau kub ntev dua los ntawm 120 ℃ mus rau ntau dua 180 ℃), thiab siv rau kev sib txuas cov kab tseem ceeb ntawm cov hniav cua turbine thiab ua cov txheej txheem rwb thaiv tsev rau cov xov hluav taws xob siab, ua tau raws li qhov yuav tsum tau siv ntev hauv sab nraum zoov lossis chaw ua haujlwm.

2) Cov khoom siv raw rau cov txheej txheem tiv taus kub/cov nplaum: Ua ib qho khoom sib txuas ntawm cov txheej txheem thiab cov nplaum, BPADA yog sib xyaw nrog cov phenolic resins thiab silicone resins los tsim cov txheej txheem tiv taus kub rau cov khoom siv hauv kev lag luam (xws li cov txheej txheem tiv thaiv xeb thiab tiv taus kub rau phab ntsa sab hauv ntawm cov boilers thiab cov kav dej), thiab cov nplaum tiv taus kub uas kho ntawm chav tsev kub rau cov hlau thiab ceramics. Cov no feem ntau siv rau kev tiv thaiv thiab kev sib txuas ntawm cov khoom siv kho tshuab thiab tshuaj lom neeg.
