Ho bonts’a theknoloji ea tlhahiso ea mica tube

Mica tube ke sekoahelo se chitja se entsoeng ka lesela la khalase le senang alkali le kenngoeng ka lehoakhoa la epoxy, le besitsoeng ka hlobo ebe le hatisoa ka chesang. Lere la lesela la khalase le na le litšobotsi tse phahameng tsa mochini. Bokaholimo ba tube ea mica bo lokela ho ba boreleli ebile bo se na bubble, oli le litšila. ‘Mala o sa lekanang, ho pikitloa hanyane joalo-joalo li maemong a lumellehang. Lipeipi tsa epoxy resin li sebelisetsoa ho sireletsa likarolo tsa lisebelisoa tsa motlakase, libaka tse mongobo le oli ea transformer.

Joalokaha bohle re tseba, ts’ebetso ea phala ea epoxy resin e ntle haholo, ka hona ts’ebetso ea tlhahiso ea phaephe ee e ntle ea epoxy lehoakhoa ke efe?

1. Senya lehoakhoa la epoxy ka bateng ea metsi ho isa ho 85-90 ° C, eketsa moemeli ea folisang ho latela resin / agent e folisang (mass ratio) = 100/45, hlohlelletsa ho qhibiliha le ho boloka ka tankeng ea sekhomaretsi ka 80-85 ° C.

2. Faeba ea khalase e entsoe ka hlobo ea mantlha ea tšepe, lehlakore le bolelele ba bolelele bo bolelele ke 45 °, ‘me bophara ba khoele ea fiber ke 2.5mm. Lera la fiber le entsoe ka 3.5mm longitudinal matsoelintsoeke + 2 dikarolo tsa circumferential matsoelintsoeke + 3.5mm teteaneng longitudinal matsoelintsoeke + 2 le dikarolo tsa circumferential matsoelintsoeke.

3. Senya tharollo ea lehoakhoa hore sekhomaretsi sa lera le potileng fiber se baloe e le 26%.

4. Kenya tube e khutsufatsang mocheso oa polasetiki mokatong o kantle, o e butsoele ka moea o chesang ebe o e thatela ka thata, ebe o thatela lera le kantle ka theipi ea khalase ea 0.2 mm le bophara ba limilimithara tse 20 ebe o e romella seboping se folisang. bakeng sa ho folisa.

5. Ho folisa taolo: qala ka ho phahamisa mocheso oa kamore ho tloha mocheso oa kamore ho ea ho 95 ° C ka sekhahla sa 3 ° C / 10min, ebe oe futhumatsa ho fihlela 160 ° C ka sekhahla se tšoanang sa ho phahama ha mocheso bakeng sa 4h, ebe oe pholile ontong ho mocheso oa kamore.

6. Phala ea mica e senyehile, theipi ea lesela la khalase e holim’a metsi ea tlosoa ebe e sebetsoa ka moo ho hlokahalang.
