LFT hlobo ke eng mme phapang ke efe le hlobo ea SMC

1. Kenyelletso ea LFT
LFT, fiber e telele e matlafalitsoeng ka thepa ea thermoplastic, Senyesemane ke Long Fiber reinforced Thermoplastics, e bapisoa le fiber e tloaelehileng e matlafalitsoeng ka thepa ea thermoplastic, hangata, bolelele ba fiber e matlafalitsoeng ke thepa ea thermoplastic e ka tlase ho 1 mm, ha LFT, Bolelele ba fiber ka kakaretso bo le teng. kholo ho feta 2 mm. Theknoloji ea hona joale ea ho sebetsa e khonne ho boloka bolelele ba fiber ho LFT ka holimo ho 5 mm.
2. Sebopeho sa LFT
Tlhahlobo ea LFT (Long Glass Fiber Reinforced Plastic) e ipapisitse le theknoloji ea tlhahlobo ea microspectrum, e sekasekang litaba tsa karolo e 'ngoe le e 'ngoe ea thepa e hlahisitsoeng ka microspectrum le ho khutlisetsa foromo ea mantlha. Lisebelisoa tse telele tsa thermoplastic tse matlafalitsoeng ka fiber li bapisoa le lisebelisoa tse tloaelehileng tsa thermoplastic tse matlafalitsoeng ka fiber. Resin ea matrix e sebelisoang haholo ke PP, e lateloe ke PA, 'me li-resin tse ling tse kang PBT, PPS, le SAN li sebelisoa hape. LFT e na le lits'ebetso tse ngata likoloing, 'me molemo o ka sehloohong ke ho feto-fetoha ha thepa eo thepa e ka kopanngoang ka eona.
Ea boraro, phapang pakeng tsa LFT le SMC
Ts'ebetso ea tlhahiso ea lihlahisoa tsa Letlapa la LFT e ts'oana haholo le SMC (Sheet Molding) ka har'a lipolasetiki tse matlafalitsoeng tsa khalase ea thermosetting. E boetse e etsoa ka ho hatisa maqephe ka hlobo. LFT ke lakane e thata e futhumatsang le ho nolofala ebe e hatelloa ka serame ka har'a hlobo, ha SMC e ntse e hatelloa ka mocheso ka mor'a hore letlapa le bonolo le batang le behoe ka har'a hlobo.
Ha ho bapisoa le leqephe la SMC, ts'ebetso ea tekheniki ea LFT e na le melemo e latelang:
1. Ha e na kotsi ebile e se na tatso, e ka ntlafatsa tikoloho ea ho sebetsa.
2. Boima bo bobebe, boima ba 'mele ke 1 ~ 1.2g / cm3 feela.
3. Lithako le lihlahisoa tsa litšila li ka sebelisoa hape ho fokotsa litšila.
4. Matla a phahame ho feta SMC, 'me matla a ts'usumetso a tsoteha haholo.
5. Ho hanyetsa kutu le ts'ebetso e ntle ea motlakase.
6. Lebelo la ho hatella sehlahisoa le lebelo ka makhetlo a 'maloa ho feta SMC,' me katleho ea tlhahiso e ntlafatsoa haholo.
