1,Ukufakwa kwe-SMCishidiisingeniso

I-SMC insulatingishidiibunjwa kusuka ku-polyester engagcwalisiwe yengilazi ye-fiber eqinisiwe imikhiqizo ebunjiwe ye-laminate ngemibala ehlukahlukene.Limfushane ngenhlanganisela yokubumba Ishidi.Izinto zokusetshenziswa eziyinhloko yi-GF (intambo ekhethekile), i-UP (i-unsaturated resin), izithasiselo ezinciphayo eziphansi, i-MD (isigcwalisi) kanye nezithasiselo ezihlukahlukene.Yaqala ukuvela eYurophu ekuqaleni kwawo-1960, futhi yathuthukiswa e-United States naseJapane cishe ngo-1965. Ekupheleni kweminyaka yama-80, izwe lethu lethula umugqa wokukhiqiza we-SMC othuthukisiwe nobuchwepheshe bokukhiqiza.

2, Cama-haracteristics

Ibhodi lokufakelwa kwe-SMC linamandla amakhulu emishini, i-flame retardant, ukumelana nokuvuza kungokwesibili kuphela ku-UPM203;Ukumelana ne-Arc, amandla e-dielectric kanye nokumelana nomthamo ophezulu;Ukumuncwa kwamanzi aphansi, ukuzinza kosayizi, i-warpage encane nezinye izici.Imikhiqizo yebhodi lokufakwa kwe-SMC isetshenziswa kakhulu ekuhlukaniseni ama-switchgear aphezulu, aphakathi nendawo naphansi.Ukusebenza kwempahla eyinhlanganisela ye-SMC, isixazululo esiyingqayizivele sokhuni, insimbi, ibhokisi lamamitha epulasitiki eliguga kalula, ukugqwala kalula, ukungezwani kahle, ukumelana nokubanda, ubuthakathaka, ukushiyeka kokungabekezeleli ilangabi elibi, impilo yesevisi emfushane, izakhiwo ezinhle kakhulu zemitha yepulasitiki eqinisiwe yengilazi. ibhokisi, linophawu oluphelele lokusebenza okungangeni manzi, ukusebenza kokugqwala, ukuvimbela ukusebenza kokwebiwa kukagesi, asikho isidingo socingo oluphansi, ukubukeka kukuhle, inokhiye ekuvikelweni nasekuvaleni uphawu, impilo ende yesevisi, ibhokisi lokusabalalisa le-SMC / ibhokisi lemitha le-SMC / imitha ye-SMC FRP ibhokisi/ibhokisi lamamitha le-SMC lisetshenziswa kakhulu ekuguquleni inethiwekhi yamandla asemaphandleni kanye nenethiwekhi yamandla asemadolobheni.

3.Inkambu yesicelo se-SMC

Imboni kagesi: zonke izinhlobo zebhodi lokuhlukanisa iKhabhinethi, ibhodi lening, ukwesekwa kwe-insulator, ukusekelwa, isembozo se-arc, ishubhu le-arc nezinhlobo ezahlukahlukene ze-insulator,

Isicishamlilo se-Arc, isibambi sokuxhumana, isibambo sebhasi, ibhokisi letheminali le-motor outlet, ibhokisi lamamitha kagesi, njll.

Imboni yezimoto: ubhampa wezimoto, i-fender, umgqomo wamasondo oyisipele, isihlalo, iphaneli yezinsimbi, ibhodi elikhanyayo, njll.

Imboni yezokwakha: zonke izinhlobo zethangi lamanzi lezakhiwo eziphakeme, i-toilet sanitary ware, ibhodi lokuhlobisa kanye neminye imikhiqizo.

Imboni yezitimela: isibani sesignali, ifreyimu yewindi lenqola, igobolondo lebhokisi lesiginali, njll.

Iv.Izimpawu nezinzuzo zezinto ze-SMC embonini yezingxenye zezimoto

1, isisindo esilula

Ezingxenyeni ezifanayo, isisindo sezinto ezihlanganisiwe ze-SMC silula ngo-20-30% kunensimbi, ehlangabezana nezidingo zensimu yezimoto ukuze kuncishiswe isisindo sezingxenye ngenkathi kuqinisekiswa amandla ezingxenye.Kungumkhiqizo ofanelekile wokonga amandla embonini yezimoto.Ngaphezu kwalokho, izingxenye ze-SMC azigcini nje ngokugcina amandla nokusetshenziswa kwamandla, kodwa futhi zifaka isandla ekuthuthukisweni kwemvelo.

2, ukusebenza komzimba okuhle kakhulu

Izakhiwo zayo ezingokomzimba zingaqhudelana kangcono nezinto zensimbi, futhi zisengakwazi ukugcina izakhiwo zemishini ngaphansi kwezimo zokushisa eziphakeme, i-thermoplastic evamile ayinakuqhathaniswa, iyinto ekahle yensimbi yepulasitiki.

3, izinga eliphezulu lokuhlanganisa inkululeko yokuklama

Izici zokugeleza kwezinto ze-SMC kanye nenqubo yokubumba inquma ukuthi izingxenye eziningi (njengezingxenye zokubeka, izixhumi, ama-stiffener, ama-flanges nezimbobo, njll.) zingafinyelela ukubunjwa kwesikhathi esisodwa, zinganciphisa inani lokubunjwa, i-tooling kanye ne-welding, ukuhlanganisa nezinye izinqubo. , ukuze kuncishiswe kakhulu Izindleko, ukusebenza kwezindleko eziphansi zezingxenye zevolumu ephansi kungenziwa.

4, ukumelana nokugqwala, ukumelana nokugoba okuhle, ukwethembeka okuphezulu

Impahla ye-SMC ngokwayo iyimpahla ekwazi ukumelana nokugqwala, ngakho-ke ayidingi ukuba i-phosphating ukuze ivimbele ukugqwala futhi ithuthukise ukusebenza kwebhondi, uma kuqhathaniswa nezicelo zepuleti lensimbi le-SMC zinganciphisa izindleko futhi zonge amandla.Okwezingxenye zezimoto ezisetshenziswa ngaphandle ngaphansi kwezimo zangaphandle ezinzima

Uma sikhuluma, luhlobo lwento eyingqayizivele.Uma kuqhathaniswa nepuleti lensimbi nepuleti le-aluminium, ipuleti le-SMC linokumelana okuhle nomthelela wezinto zangaphandle nama-dents kanye nekhono lokuphinda libophe amazinyo.

5,ukumelana nokushisa okuhle kakhulu nokunamathela

Imikhiqizo ye-SMC inokumelana nokushisa okuhle.Imikhiqizo ye-SMC ingagcina ukuqina kohlangothi ukusuka ku -50 ° C kuya +200 ° C ngemva kokukhululwa.Impahla ye-SMC iyinto efanelekile kakhulu yobuchwepheshe bokufafaza ipuleti lensimbi, ngoba i-SMC inokwanda okufanayo okushisayo kuya kwensimbi.

I-coefficient kanye nokumelana nokushisa, emva kokufafaza imikhiqizo ye-SMC ingelashwa ekushiseni okufanayo kwehhavini njenge-coating yensimbi.Ngaphezu kwalokho, i-SMC inokuguquguquka okuhle kwenqubo, nakuba ibhodi le-SMC lingadingi ukwelashwa kwe-phosphating, kodwa uma inqunyelwe inqubo yokukhiqiza yasekuqaleni, idinga ukudlula ohlelweni lokwelapha lwe-phosphating, ibhodi le-SMC lingahlangabezana nezidingo zalesi sici, izingxenye ze-SMC zingakwazi. futhi icutshungulwe ngohlelo lwe-electrophoresis spraying (EDPO).
