Kupanga jekeseni wazinthu za BMC

BMC (DMC) zakuthupi ndi chidule cha chochuluka (mtanda) akamaumba mankhwala, ndiye chochuluka akamaumba mankhwala.Nthawi zambiri amatchedwa unsaturated polyester gulu akamaumba pawiri ku China.Zida zake zazikulu zopangira ndi prepregs misa yopangidwa ndi GF (unsaturated resin), MD (filler calcium carbonate) ndi zowonjezera zosiyanasiyana.Zida za BMC zidagwiritsidwa ntchito koyamba ku West Germany ndi Britain m'ma 1960, kenako zidapangidwa kwambiri ku United States ndi Japan m'ma 1970 ndi 1980 motsatana.ChifukwaBMC zambiri akamaumba mankhwalaali ndi zida zabwino kwambiri zamagetsi, zida zamakina, kukana kutentha, kukana kwa dzimbiri kwa mankhwala, komanso kutengera njira zosiyanasiyana zowumba, zimatha kukwaniritsa zofunikira zazinthu zosiyanasiyana, motero zimatchuka kwambiri ndi ogwiritsa ntchito.

(1) Makhalidwe ndi kugwiritsa ntchito BMC

BMC ili ndi zinthu zabwino zakuthupi, zamagetsi komanso zamakina, motero imagwiritsidwa ntchito kwambiri, monga kupanga zida zamakina monga zida za gearbox, mapaipi olowera, zophimba ma valve, mabampu ndi zina zotero;Amagwiritsidwanso ntchito kwambiri muzoyendetsa ndege, zomangamanga, mipando,mankhwala aukhondondi zina zomwe zimafuna kukana zivomezi, kuchedwa kwamoto, kukongola ndi kulimba;M'malo ake amagetsi achikhalidwe, kugwiritsidwa ntchito kwake kumachulukirachulukira.

(2) Zinthu zodziwika bwino

Zigawo zamagetsi (insulator, kusintha 29, bokosi la mita,circuit breaker chipolopolo, block block, zipolopolo zosiyanasiyana zapakhomo kapena zamalonda zama electromechanical), zida zamagalimoto (zowunikira zowunikira, chitseko chakumbuyo, chipolopolo cha speaker, etc.), chipolopolo cha mita, chipolopolo cha zida zokuzira mawu.

(3) BMC kupanga njira

Makina opangira jakisoni a BMC makamaka ndi njira yopangira zinthu zambiri za BMC, zomwe zimakakamizika kulowa mu mbiya ya BMC kudzera mu feeder ya BMC, kenako zimaperekedwa kutsogolo kwa mbiya kudzera pa screw, kenako kubayidwa mu nkhungu kuchiritsa ndi kuumba.

BMC ndi zida zopangira thermosetting.Kutentha kwa mbiya ya makina opangira jekeseni sikuyenera kukhala kokwera kwambiri.Nthawi zambiri imayikidwa pa madigiri 60 kuti athandizire kuyenda kwa zinthu.

Makina omangira jakisoni a BMC makamaka ndi zida zaukadaulo zopangira zida za thermosetting lumpy.Pali seti ya ma hydraulic system mu gawo lodyetsera, lomwe limakakamiza zinthu za lumpy mu mbiya pamene screw ikuyembekezeka.Makina opangira jakisoni a BMC ndi oyenera kuumba ndi mawonekedwe ovuta, omwe amakonzedwa ndi jekeseni, ndikuchita bwino kwazinthu komanso kutsika kwantchito.

Njira zomangira za BMC zimaphatikizira kuponderezana, kusamutsa ndikuumba jekeseni.Posachedwapa, kuumba jekeseni ndiyo njira yaikulu.

① Njira yophatikizira, onani njira yopangira ya SMC.

② Njira yosinthira.Zidazi zili ndi mtundu wa mphika ndi mtundu wothandiza wa pistoni, makamaka mtundu wa pistoni wothandiza.
