Kushandiswa

1. Kugadzira zvigadzirwa zve polyimide (PI) zvine chinangwa chakawanda

Uku ndiko kushandiswa kwakajairika uye kwakakosha kweBPADA. BPADA ine polycondensed nema common diamine monomers akadai se 4,4' -diaminodiphenyl ether (ODA) kuti igadzire polyimide inosanganisa "kupisa uye nyore kushandisa". Rudzi urwu rwePI, nekuda kwekuvapo kwe ether bonds uye isopropyl groups muchimiro chayo chemamorekuru, inoramba ichidzivirira kupisa kwakanyanya kwePI (tembiricha yekushandira kwenguva refu 180-220℃). BPADA iri nyorewo kugadzirwa kuita mafirimu, maplate, nezvimwewo pane PI yakajairika, uye inowanzo shandiswa mu:

1) Zvikamu zvekudzivirira kupisa mumunda wemagetsi: Firimu repasi nefirimu rekufukidza rekugadzira mabhodhi edunhu anochinjika akadhindwa (FPC), pamwe chete nevhanishi yepepa/vhanishi inodzivirira kupisa kwakanyanya yemamota nematransformer, kuti isangane nezvinodiwa zve "miniaturization + tembiricha" zvezvikamu zvemagetsi, zvakaita sekudzivirira kupisa kwemukati kwemamota emagetsi evatengi nemamota eindasitiri.

2) Zvinhu zvemaindasitiri zvinodzivirira kupisa kwakanyanya: Zvakagadzirwa kuita maPI plates nemachubhu, zvinoshandiswa kumabhuraketi anodzivirira kupisa kwakanyanya akatenderedza mainjini emotokari uye zvikamu zvemidziyo yemumba zvinodzivirira kupisa mukati (senge maovheni nemaovheni ema microwave). Zvinogona kutsungirira kupisa kuri pamusoro pe150℃ kwenguva yakareba, uye zvinodzivirira kukwegura nekutsemuka.

2. Gadzirisa maresini echinyakare kuti uvandudze mashandiro

Mukugadzirisa resin yakajairika, BPADA, se "monomer inosimbisa kupisa", inowanzoshandiswa kugadzirisa mashandiro e epoxy resins nema phenolic resins uye kuwedzera mamiriro ekushandiswa kwavo:

1) Kugadziriswa kweresin yeEpoxy: Kana ikasanganiswa neresin ye epoxy, BPADA inowedzera kuramba kupisa kwakanyanya kweresin (inowedzera kuramba kupisa kwenguva refu kweresin yakaporeswa kubva pa120℃ kusvika pamusoro pe180℃), uye inoshandiswa kubatanidza matanda makuru emashizha emhepo uye sechivharo chekudzivirira kupisa kwetambo dzine simba guru, ichizadzisa zvinodiwa zvekushandiswa kwenguva refu munzvimbo dzekunze kana dzemaindasitiri.

2) Zvinhu zvepakutanga zvemachira/manamira anodzivirira kupisa kwakanyanya: Sechikamu chinobatanidza machira nemanamatira, BPADA inosanganiswa nema phenolic resins nema silicone resins kuti igadzire machira anodzivirira kupisa kwakanyanya emidziyo yeindasitiri (yakadai semachira anodzivirira kupisa uye anodzivirira kupisa emadziro emukati memaboiler nemapaipi), uye manamira anodzivirira kupisa kwakanyanya anoporesa patembiricha yemukamuri yesimbi neceramics. Izvi zvinowanzoshandiswa kudzivirira nekubatanidza michina yemakanika nemakemikari.
