1,Ukufakwa kwe-SMCiphephaintshayelelo

SMC insulatingiphephaibunjwe ukusuka kwi-polyester engaxutywanga yeglasi ifayibha eqiniswe i-laminate ebunjiweyo kwiimveliso ezinemibala eyahlukeneyo.Lifutshane kwikhompawundi yokubumba iPhepha.Izinto eziphambili ze-raw yi-GF (umsonto okhethekileyo), i-UP (i-resin unsaturated), izongezo ezisezantsi zokucutheka, i-MD (i-filler) kunye neentlobo ezahlukeneyo zokudibanisa.Yaqala ukubonakala eYurophu ekuqaleni kweminyaka yoo-1960, yaza yaphuhliswa eUnited States naseJapan malunga no-1965. Ekupheleni kwe-80, ilizwe lethu lazisa umgca wemveliso we-SMC wangaphandle kunye nobugcisa bemveliso.

2, Ci-haracteristics

Ibhodi yokufakela i-SMC inamandla amakhulu omatshini, i-flame retardant, ukuxhathisa ukuvuza okwesibini kuphela kwi-UPM203;Ukumelana ne-Arc, amandla e-dielectric kunye nokumelana nombane ophezulu;Ukufunxa kwamanzi aphantsi, ukuzinza kobungakanani, i-warpage encinci kunye nezinye iimpawu.Iimveliso zebhodi yokugquma ye-SMC zisetyenziswa ikakhulu kulwahlulo oluphezulu, oluphakathi nolusezantsi lwesixhobo sokugquma i-switchgear.Ukusebenza kwezinto ezihlanganisiweyo ze-SMC, isisombululo esikhethekileyo somthi, intsimbi, ibhokisi yeemitha zeplastiki kulula ukuguga, kulula ukugqwesa, ukugquma okulambathayo, ukunganyangeki, ukumelana nokubanda, ukusilela, ukusilela kokungakhathali kwamadangatye, ubomi obufutshane benkonzo, iipropathi ezigqwesileyo zefiber yeglasi eyomelezwe imitha yeplastiki. ibhokisi, inetywina elipheleleyo lokusebenza okungangeni manzi, ukusebenza komhlwa, ukuthintela ukusebenza okubiwe ngumbane, akukho mfuneko yocingo lwasemhlabeni, imbonakalo entle, inesitshixo kukhuseleko kunye nokutywinwa, ubomi benkonzo ende, ibhokisi yokuhambisa ye-SMC / ibhokisi yemitha ye-SMC / imitha ye-SMC FRP ibhokisi/Ibhokisi yemitha ye-SMC isetyenziswa kakhulu kuguqulo lothungelwano lwamandla asemaphandleni kunye nothungelwano lwamandla asezidolophini.

3.Indawo yesicelo se-SMC

Umzi-mveliso wombane: zonke iintlobo zebhodi yokwahlula kwikhabhathi yokutshintsha, ibhodi yelinen, inkxaso yokugquma, inkxaso, isigqubuthelo se-arc, ityhubhu ye-arc kunye neentlobo ezahlukeneyo ze-insulator,

Isicimi-mlilo se-Arc, isibambi soqhagamshelwano, isikhonkwane sebhasi, ibhokisi ye-motor outlet terminal, ibhokisi yemitha yombane, njl.

Umzi-mveliso weemoto: ibumper yemoto, i-fender, umgqomo wamatayara asecaleni, isihlalo, ipaneli yesixhobo, ibhodi yedazzle, njl.

Umzi-mveliso wokwakha: zonke iintlobo zetanki yamanzi ekwisakhiwo esiphakamileyo, i-toilet sanitary ware, ibhodi yokuhombisa kunye nezinye iimveliso.

Ishishini likaloliwe: isibane somqondiso, isakhelo sefestile yenqwelo, iqokobhe lebhokisi yemiqondiso, njl.

Iv.Iimpawu kunye neengenelo zezinto ze-SMC kushishino lwezahlulo zemoto

1, ubunzima obulula

Kwiindawo ezifanayo, ubunzima bezinto ezidibeneyo ze-SMC ziyi-20-30% ilula kunentsimbi, ehlangabezana neemfuno zentsimi yeemoto ukunciphisa ubunzima beengxenye ngelixa uqinisekisa amandla amacandelo.Yimveliso efanelekileyo yokugcina amandla kumashishini eemoto.Ngaphezu koko, amacandelo e-SMC awagcini nje ukugcina amandla kunye nokusetyenziswa kwamandla, kodwa anegalelo ekuphuculweni kokusingqongileyo.

2, ukusebenza kakuhle komzimba

Iimpawu zayo ezibonakalayo zinokukhuphisana kakuhle kunye nezixhobo zetsimbi, kwaye zisenako ukugcina iipropati zomatshini phantsi kweemeko eziphezulu zokushisa, i-thermoplastic jikelele ayinakuthelekiswa, yinto efanelekileyo yensimbi yeplastiki.

3, iqondo eliphezulu lokudibanisa inkululeko yoyilo

Iimpawu zokuhamba kwezinto ze-SMC kunye nenkqubo yokubumba inquma ukuba iindawo ezininzi (ezifana neendawo zokubeka, izihlanganisi, i-stiffeners, i-flanges kunye nemingxuma, njl.njl.) zinokufezekisa ukubumba kwexesha elinye, kunokunciphisa inani lokubumba, izixhobo kunye ne-welding, indibano kunye nezinye iinkqubo. , ukuze kuncitshiswe kakhulu Iindleko, ukusebenza kwexabiso eliphantsi leenxalenye zevolumu ephantsi kunokuphunyezwa.

4, ukunganyangeki kwe-corrosion, ukumelana nokugoba okulungileyo, ukuthembeka okuphezulu

Isixhobo se-SMC ngokwaso sisixhobo esinganyangekiyo kwi-corrosion, ngoko akufuneki ukuba sibe ne-phosphating ukuze kuthintelwe ukubola kunye nokuphucula ukusebenza kwebhondi, xa kuthelekiswa nezicelo zepleyiti zensimbi ze-SMC kunokunciphisa iindleko kunye nokugcina amandla.Kwiindawo zeemoto ezisetyenziselwa ngaphandle phantsi kweemeko zangaphandle ezinzima

Ukuthetha, luhlobo lwezinto ezizodwa.Xa kuthelekiswa nepleyiti yentsimbi kunye nepleyiti ye-aluminium, ipleyiti ye-SMC inokumelana kakuhle nefuthe lezinto zangaphandle kunye nezibonda kunye nesakhono sokuphinda sibuyele.

5,ukumelana nobushushu obugqwesileyo kunye nokwaleka

Iimveliso ze-SMC zinokuxhathisa ubushushu obuhle.Iimveliso ze-SMC zinokugcina uzinzo lwe-dimensional ukusuka -50 ° C ukuya +200 ° C emva kokukhululwa.Izinto ze-SMC zezona zinto zifanelekileyo kwitekhnoloji yokutshiza ipleyiti yentsimbi, kuba i-SMC inokwandiswa kwe-thermal efanayo kwintsimbi.

I-Coefficient kunye nokumelana nobushushu, emva kokutshiza iimveliso ze-SMC zinokunyangwa kwiqondo lokushisa elifanayo le-oven njengentsimbi yentsimbi.Ukongeza, i-SMC inenkqubo elungileyo yokuguquguquka, nangona ibhodi ye-SMC ayifuni unyango lwe-phosphating, kodwa ukuba inqunyelwe yinkqubo yokuvelisa yasekuqaleni, kufuneka ihambe ngenkqubo yonyango ye-phosphating, ibhodi ye-SMC inokuhlangabezana neemfuno zalo mba, iinxalenye ze-SMC ziyakwazi kwakhona kusetyenzwe nge-electrophoresis spraying (EDPO) inkqubo.
