1. Kopanya dihlahiswa tsa polyimide (PI) tse sebetsang ka kakaretso tse nang le sepheo se seholo

Ena ke ts'ebeliso e tloaelehileng le ea mantlha ea BPADA. BPADA e koahetsoe ka polycondensed ka li-monomers tse tloaelehileng tsa diamine tse kang 4,4' -diaminodiphenyl ether (ODA) ho theha polyimide e kopanyang "ho hanyetsa mocheso le ho sebetsa habonolo". Mofuta ona oa thepa ea PI, ka lebaka la boteng ba liboto tsa ether le lihlopha tsa isopropyl sebopehong sa eona sa limolek'hule, o boloka khanyetso ea mocheso o phahameng oa PI (mocheso oa tšebeletso ea nako e telele oa 180-220℃). BPADA e boetse e bonolo ho etsoa lifilimi, lipoleiti, jj. ho feta PI e tloaelehileng, 'me e sebelisoa hangata ho:

1) Likarolo tsa motheo tsa ho thibela mocheso lefapheng la lisebelisoa tsa elektroniki: Filimi ea motheo le filimi ea sekoahelo bakeng sa ho etsa liboto tsa potoloho tse hatisitsoeng tse tenyetsehang (FPC), hammoho le varnish ea pampiri/varnish e thibelang mocheso e sa keneleng mocheso o phahameng bakeng sa lienjene le li-transformer, ho fihlela litlhoko tsa "miniaturization + ho hanyetsa mocheso" tsa likarolo tsa elektroniki, joalo ka tšireletso ea ka hare ea ho thibela mocheso bakeng sa lisebelisoa tsa elektroniki tsa bareki le lienjene tsa indasteri.

2) Likarolo tse akaretsang tse hanelang mocheso o phahameng oa indasteri: Li entsoe ka lipoleiti le li-tube tsa PI, li sebelisoa bakeng sa li-bracket tse hanelang mocheso o phahameng tse potolohileng lienjene tsa likoloi le likarolo tse ka hare tse hanelang mocheso oa lisebelisoa tsa ntlo (joalo ka lionto le lionto tsa microwave). Li ka mamella mocheso o fetang 150℃ ka nako e telele, 'me li hanella ho tsofala le ho petsoha.

2. Fetola li-resin tse tloaelehileng ho ntlafatsa ts'ebetso

Phetohong ea resin e tloaelehileng, BPADA, e le "monomer e matlafatsang e hanelang mocheso", e sebelisoa hangata ho ntlafatsa ts'ebetso ea li-resin tsa epoxy le li-resin tsa phenolic le ho atolosa maemo a ts'ebeliso ea tsona:

1) Phetoho ea resin ea epoxy: Ha e kopantsoe le resin e tloaelehileng ea epoxy, BPADA e eketsa khanyetso ea mocheso o phahameng oa resin (e eketsa khanyetso ea mocheso oa nako e telele oa resin e phekotsoeng ho tloha ho 120℃ ho ea ho feta 180℃), 'me e sebelisoa bakeng sa ho kopanya mahlaseli a maholo a mahare a turbine ea moea le e le sekoahelo sa ho thibela mocheso bakeng sa likhoele tsa motlakase o phahameng, ho fihlela litlhoko tsa ts'ebeliso ea nako e telele libakeng tsa kantle kapa tsa indasteri.

2) Lisebelisoa tsa mantlha tse tala bakeng sa liphahlo/likhomaretsi tse hanelang mocheso o phahameng: Jwalo ka karolo e kopanyang liphahlo le likhomaretsi, BPADA e kopanngoa le li-resin tsa phenolic le li-resin tsa silicone ho hlahisa liphahlo tse hanelang mocheso o phahameng bakeng sa lisebelisoa tsa indasteri (tse kang liphahlo tse thibelang mafome le tse hanelang mocheso bakeng sa mabota a ka hare a liboiler le liphaephe), le likhomaretsi tse hanelang mocheso o phahameng tse folisang mochesong oa kamore bakeng sa litšepe le liseramike. Tsena li sebelisoa hangata bakeng sa tšireletso le ho kopanya lisebelisoa tsa mechini le lik'hemik'hale.
