Bakeng sa lipotso tse ling le likarabo mabapi le epoxy glass fiber cloth laminate, u tla tseba haholoanyane ka mor’a ho bala

Epoxy glass fiber cloth laminate ke thepa ea motheo ea liboto tsa potoloho tse hatisitsoeng. Thepa ke fiber ea khalase, ‘me karolo ea mantlha ke SiO2. Fiber ea khalase e lohuoa ka lesela ‘me e koahetsoe ka epoxy resin, e leng mokhoa o rarahaneng haholo.

1. E sebelise ho ba le tekanyo e itseng ea polasetiki le boima bo kang khetla ea lisebelisoa tse ling kapa mechine e kang likoloi, li-yachts, joalo-joalo.

2, substrate ea boto ea potoloho.

1. Litlhaloso tsa boto ea lesela la khalase ea epoxy ke eng mme epoxy board ke eng?

Boto ea lesela la khalase ea epoxy e mosehla, thepa ke epoxy resin, ‘me epoxy glass fiber board e entsoe ka fiber ea khalase, eo hangata e leng tala ea metsi. Ho hanyetsa mocheso oa eona ho phahame ho feta boto ea lesela la khalase ea epoxy, ‘me ho kenngoa ha eona likarolong tsohle ho boetse ho molemo. Ka lesela la khalase ea epoxy

2. Phapano ke efe lipakeng tsa boto ea epoxy resin le board ea lesela la epoxy glass?

Ho ea ka polelo e tsebahalang, tse peli li hlile li tšoana, empa boto ea epoxy resin e siile lisebelisoa tse matlafatsang.

Ho na le phapang pakeng tsa tsena tse peli. Ho na le mefuta e mengata ea lisebelisoa tse matlafatsang bakeng sa boto ea epoxy resin, e tloaelehileng ke lesela la khalase, hammoho le mathe a khalase, fiber ea khalase, mica, joalo-joalo, ‘me li na le ts’ebeliso e fapaneng.

Epoxy fiberglass board e boetse e bitsoa reinforced fiberglass board. E loketse lisebelisoa tsa mechine, tsa motlakase le tsa elektronike tse nang le li-insulation tse phahameng. E na le thepa e phahameng ea mechine le ea dielectric, ho hanyetsa mocheso o motle le ho hanyetsa mongobo.

E na le litšobotsi tse latelang:

1. Mefuta e sa tšoaneng

Li-resin tse fapaneng, liakhente tse phekolang, le litsamaiso tsa ho fetola li ka ikamahanya le litlhoko tsa lits’ebetso tse fapaneng foromong, ‘me mefuta e ka ba ho tloha ho viscosity e tlase haholo ho isa ho lintho tse tiileng tse qhibilihang.

2. Pheko e bonolo

Khetha mefuta e fapaneng ea mefuta e fapaneng ea pheko, sistimi ea epoxy resin e ka batla e phekoleha maemong a mocheso a 0～180℃.

3, ho khomarela ka matla

Ho ba teng ha polar hydroxyl le ether bond tse teng mokotleng oa molek’hule oa epoxy resin ho etsa hore e be le mamarelo a phahameng linthong tse fapaneng. The shrinkage ea epoxy resin e tlaase ha e phekoloa, ‘me khatello ea ka hare e hlahisoang e nyenyane, e thusang ho ntlafatsa matla a ho khomarela.

4, ho fokotseha ho tlase

“Karabelo ea epoxy resin le pheko e sebelisitsoeng e etsoa ka karabelo e tobileng ea tlatsetso kapa karabelo e bulehileng ea “polymerization” ea lihlopha tsa epoxy ka molek’hule ea resin, ‘me ha ho na metsi kapa lihlahisoa tse ling tse sa fetoheng tse lokolloang. Ha li bapisoa le li-resin tsa polyester tse sa tsitsang le li-phenolic resin, li bontša ho fokotseha haholo (ka tlase ho 2%) nakong ea ho phekola.

5. Thepa ea mechine

Sistimi ea epoxy resin e phekotsoeng e na le thepa e ntle haholo ea mochini.
