BMC Hydraulic press forming process process

BMC ndi chidule cha magalasi CHIKWANGWANI analimbitsa unsaturated poliyesitala thermosetting pulasitiki, ndipo pakali pano ndi anthu ambiri ntchito mtundu wa analimbitsa thermosetting pulasitiki.

Mawonekedwe a BMC ndi ntchito
BMC ili ndi zinthu zabwino zakuthupi, zamagetsi komanso zamakina, motero ili ndi ntchito zosiyanasiyana, monga kupanga zida zamakina monga mapaipi olowera, zophimba ma valve, ndi zovundikira manhole wamba ndi ma rimu.Amagwiritsidwanso ntchito kwambiri paulendo wa pandege, zomangamanga, mipando, zida zamagetsi, ndi zina zambiri, zomwe zimafuna kukana zivomezi, kuwonongeka kwa malawi, kukongola ndi kulimba.

Makhalidwe a BMC Processing
1. Kusungunuka: BMC imakhala ndi madzi abwino ndipo imatha kusunga madzi abwino pansi pa kupanikizika kochepa.
2. Kuchiza: Kuthamanga kwa machiritso a BMC kumakhala mofulumira, ndipo nthawi yochiritsa ndi 30-60 masekondi / mm pamene kutentha kwa nkhungu ndi 135-145 ° C.
3. Mlingo wa Shrinkage: Mlingo wa kuchepa kwa BMC ndi wotsika kwambiri, pakati pa 0-0.5%.Mlingo wa shrinkage ungasinthidwenso powonjezera zowonjezera pakufunika.Ikhoza kugawidwa m'magulu atatu: palibe kuchepa, kuchepa pang'ono, ndi kuchepa kwakukulu.
4. Colorability: BMC ili ndi colorability wabwino.
5. Zoipa: nthawi youmba ndi yaitali, ndipo burr mankhwala ndi lalikulu.

BMC compression mawonekedwe
BMC psinjika akamaumba ndi kuwonjezera kuchuluka kwa akamaumba pawiri (agglomerate) mu nkhungu preheated, pressurize ndi kutentha, ndiyeno kulimbitsa ndi mawonekedwe.Njira yeniyeniyo ndikuyezera → kudyetsa → kuumba → kudzaza (agglomerate ikupanikizika Imayenda ndikudzaza nkhungu yonse) → kuchiritsa → (kuchiritsidwa kwathunthu pambuyo poyisunga pamitsempha ndi kutentha kwa nthawi inayake) → kutsegula nkhungu ndi kutulutsa mankhwala→kugaya burr, ndi zina.→zomaliza.

BMC psinjika akamaumba ndondomeko zinthu
1. Kumangirira kuthamanga: 3.5-7MPa pazinthu wamba, 14MPa pazinthu zokhala ndi zofunikira zapamwamba.
2. Kutentha kwa nkhungu: Kutentha kwa nkhungu nthawi zambiri kumakhala 145 ± 5 ° C, ndipo kutentha kwa nkhungu kokhazikika kumatha kutsitsidwa ndi 5-15 ° C pakugwetsa.
3. Nkhungu clamping liwiro: yabwino nkhungu clamping akhoza anamaliza mkati 50 masekondi.
4. Kuchiritsa nthawi: Nthawi yochiritsa mankhwala ndi makulidwe a khoma la 3mm ndi mphindi 3, nthawi yochiritsa ndi makulidwe a khoma la 6mm ndi mphindi 4-6, ndipo nthawi yochiritsa ndi makulidwe a 12mm ndi 6-10. mphindi.
