1,Insulation ya SMCpepalamawu oyamba

SMC insulatingpepalaamapangidwa kuchokera ku unsaturated poliyesitala galasi CHIKWANGWANI analimbitsa laminate kuumbidwa mankhwala mitundu yosiyanasiyana.Ndichidule chomangirira Mapepala.Zida zazikulu zopangira ndi GF (ulusi wapadera), UP (unsaturated resin), zowonjezera zowonjezera, MD (filler) ndi zowonjezera zosiyanasiyana.Zinayamba kuonekera ku Ulaya kumayambiriro kwa zaka za m'ma 1960, ndipo zinapangidwa ku United States ndi Japan kuzungulira 1965. Kumapeto kwa zaka za m'ma 80, dziko lathu linayambitsa mzere wa kupanga SMC wakunja ndi luso lopanga kupanga.

2, Czovuta

SMC Insulation board ili ndi mphamvu zamakina apamwamba kwambiri, osawotcha moto, kukana kutayikira ndi kwachiwiri kwa UPM203;Kukana kwa Arc, mphamvu ya dielectric ndi kukana kwamagetsi apamwamba;Mayamwidwe otsika amadzi, kukhazikika kwa kukula, tsamba laling'ono lankhondo ndi mawonekedwe ena.Zogulitsa za SMC insulation board zimagwiritsidwa ntchito kwambiri pamagawo apamwamba, apakatikati komanso otsika ma switchgear insulation.SMC composite material performance, yankho lapadera la nkhuni, chitsulo, pulasitiki mita bokosi yosavuta kukalamba, yosavuta kuwononga, kusungunula kosauka, kukana kuzizira, kusauka, zofooka za kuchedwa kwamoto, moyo waufupi wautumiki, katundu wabwino kwambiri wa magalasi opangidwa ndi galasi fiber olimbitsa mita pulasitiki. bokosi, lili ndi chisindikizo chamtheradi chosakhala ndi madzi, magwiridwe antchito a dzimbiri, kuletsa kubedwa kwa magetsi, osafunikira waya pansi, mawonekedwe okongola, okhala ndi loko pachitetezo chachitetezo ndi kusindikiza, moyo wautali wautumiki, bokosi la SMC / SMC mita bokosi / SMC FRP mita bokosi / SMC mita bokosi amagwiritsidwa ntchito kwambiri pakusintha maukonde amagetsi akumidzi ndi maukonde amagetsi akumidzi.

3.SMC ntchito gawo

Makampani amagetsi: mitundu yonse ya bolodi yogawa kabati, bolodi loyikapo, chithandizo cha kutchinjiriza, chithandizo, chivundikiro cha arc, chubu cha arc ndi mitundu yosiyanasiyana ya insulator,

Chozimitsira moto cha Arc, cholumikizira, cholumikizira mabasi, bokosi lamagetsi lamagetsi, bokosi la mita yamagetsi, ndi zina.

Makampani opanga magalimoto: bumper yamagalimoto, fender, bin yopuma, mpando, gulu la zida, bolodi lowala, ndi zina zambiri.

Makampani omanga: mitundu yonse ya thanki yamadzi yomanga yokwera kwambiri, zimbudzi zaukhondo, bolodi lokongoletsa ndi zinthu zina.

Makampani a njanji: nyali yowunikira, chimango chazenera chonyamulira, chipolopolo cha bokosi lazizindikiro, etc.

Iv.Makhalidwe ndi maubwino azinthu za SMC pakuumba magawo agalimoto

1, kulemera kochepa

Kwa magawo omwewo, kulemera kwa zinthu zophatikizika za SMC ndi 20-30% zopepuka kuposa zitsulo, zomwe zimakwaniritsa zofunikira pamunda wamagalimoto kuti muchepetse kulemera kwa magawo ndikuwonetsetsa mphamvu za magawowo.Ndi chinthu choyenera kupulumutsa mphamvu pamakampani opanga magalimoto.Kuphatikiza apo, zigawo za SMC sizimangopulumutsa mphamvu ndi mphamvu zamagetsi, komanso zimathandizira kukonza chilengedwe.

2, kuchita bwino kwambiri kwa thupi

Maonekedwe ake akuthupi amatha kupikisana bwino ndi zida zachitsulo, ndipo amatha kukhalabe ndi zida zamakina pansi pa kutentha kwambiri, ndi thermoplastic yosayerekezeka, ndi chinthu choyenera chitsulo chapulasitiki.

3, ufulu wapamwamba wogwirizanitsa mapangidwe

SMC zinthu otaya makhalidwe ndi akamaumba ndondomeko amatsimikiza kuti mbali zambiri (monga malo mbali, zolumikizira, stiffeners, flanges ndi mabowo, etc.) akhoza kukwaniritsa nthawi imodzi akamaumba, akhoza kuchepetsa chiwerengero cha zisamere pachakudya, tooling ndi kuwotcherera, msonkhano ndi njira zina. , kuti muchepetse kwambiri Mtengo, ntchito yotsika mtengo ya magawo otsika kwambiri imatha kuchitika.

4, kukana dzimbiri, kukana bwino kupindika, kudalirika kwakukulu

Zinthu za SMC zokha ndizosamva dzimbiri, chifukwa chake sizifunika kukhala phosphating kuti ziteteze dzimbiri ndikuwongolera magwiridwe antchito, poyerekeza ndi ntchito zachitsulo za SMC zimatha kuchepetsa mtengo ndikupulumutsa mphamvu.Kwa mbali zamagalimoto zomwe zimagwiritsidwa ntchito panja pansi pazovuta zakunja

Ponena za, ndi mtundu wa zinthu zapadera.Poyerekeza ndi mbale yachitsulo ndi mbale ya aluminiyamu, mbale ya SMC imakana bwino kukhudzidwa ndi zinthu zakunja ndi madontho ndi luso lobwezeretsanso.

5,kwambiri kutentha kukana ndi zokutira

Zogulitsa za SMC zimakhala ndi kutentha kwabwino.Zogulitsa za SMC zimatha kukhala zokhazikika kuchokera -50 ° C mpaka +200 ° C zitatulutsidwa.Zinthu za SMC ndizoyenera kwambiri paukadaulo wopopera zitsulo, chifukwa SMC ili ndi kukula kofanana ndi chitsulo.

Coefficient ndi kukana kutentha, pambuyo kupopera mankhwala SMC akhoza kuchiritsidwa pa kutentha ng'anjo yomweyo monga ❖ kuyanika zitsulo.Kuphatikiza apo, SMC ili ndi njira yabwino yosinthira, ngakhale bolodi la SMC silifuna chithandizo cha phosphating, koma ngati lili ndi malire ndi njira yoyambira yopanga, imayenera kudutsa njira yochizira ya phosphating, bolodi la SMC limathanso kukwaniritsa zofunikira za gawoli, magawo a SMC amatha. Komanso kukonzedwa ndi electrophoresis kupopera mbewu mankhwalawa (EDPO) dongosolo.
