BMC ni impfunyapfunyo ya fibre yibirahure ishimangirwa na polyester ya polyester ituzuye, kandi kuri ubu ni ubwoko bukoreshwa cyane muri plastiki ya termosetting.
Ibiranga BMC
BMC ifite imiterere myiza yumubiri, amashanyarazi nubukanishi, kuburyo ifite uburyo butandukanye bwo gukoresha, nko gukora ibice byubukanishi nk'imiyoboro ifata, ibifuniko bya valve, hamwe na manhole isanzwe hamwe na rim.Irakoreshwa kandi cyane mu ndege, ubwubatsi, ibikoresho, ibikoresho by'amashanyarazi, n'ibindi, bisaba kurwanya umutingito, kutagira umuriro, ubwiza no kuramba.
Ibiranga BMC
1. Amazi: BMC ifite amazi meza kandi irashobora kugumana amazi meza munsi yumuvuduko muke.
2. Gukiza: Umuvuduko wo gukiza wa BMC urihuta cyane, kandi igihe cyo gukira ni amasegonda 30-60 / mm mugihe ubushyuhe bwo kubumba ari 135-145 ° C.
3. Igipimo cyo kugabanuka: Igabanuka rya BMC riri hasi cyane, hagati ya 0-0.5%.Igipimo cyo kugabanuka nacyo gishobora guhinduka wongeyeho inyongera nkuko bikenewe.Irashobora kugabanywamo ibice bitatu: nta kugabanuka, kugabanuka gake, no kugabanuka cyane.
4. Amabara: BMC ifite amabara meza.
5. Ibibi: igihe cyo kubumba ni kirekire, kandi ibicuruzwa burr ni binini.
BMC yogusenyera
BMC compression molding ni ukongeramo umubare runaka wibintu (agglomerate) muburyo bwashyushye, kanda kandi ushushe, hanyuma ushikame kandi ushire.Inzira yihariye ni gupima → kugaburira → gushushanya → kuzuza (agglomerate iri munsi yigitutu Iratemba kandi yuzuza ifu yose) → gukiza → (gukira neza nyuma yo kuyigumya kumuvuduko wubushyuhe n'ubushyuhe mugihe runaka) → gufungura kubumba no gufata ibicuruzwa → gusya burr, nibindi → ibicuruzwa byarangiye.
BMC compression molding process conditions
1. Umuvuduko ukabije: 3.5-7MPa kubicuruzwa bisanzwe, 14MPa kubicuruzwa bifite ubuso buhanitse.
2. Ubushyuhe bwo kubumba: Ubushyuhe bwububiko muri rusange ni 145 ± 5 ° C, kandi ubushyuhe bwagenwe burashobora kugabanuka kuri 5-15 ° C kugirango bimanuke.
3. Umuvuduko wo gufunga umuvuduko: gufata neza neza birashobora kurangira mumasegonda 50.
4. Igihe cyo gukiza: Igihe cyo gukiza cyibicuruzwa bifite uburebure bwurukuta rwa 3mm ni iminota 3, igihe cyo gukira hamwe nuburebure bwurukuta rwa 6mm ni iminota 4-6, naho igihe cyo gukira hamwe nuburebure bwurukuta rwa 12mm ni 6-10 iminota.
