Ukukhiqizwa kokubumba komjovo wezinto ze-BMC

I-BMC (DMC) impahla isifinyezo senqwaba (inhlama) yokubumba inhlanganisela, okungukuthi, izinhlanganisela zokubumba ngobuningi.Ivamise ukubizwa nge-unsaturated polyester group molding compound e-China.Izinto zayo zokusetshenziswa eziyinhloko ama-mass prepregs enziwe nge-GF (i-glass fibre eqoshiwe), phezulu (i-unsaturated resin), i-MD (filler calcium carbonate) kanye nezithasiselo ezihlukahlukene.Izinto ze-BMC zaqala ukusetshenziswa endaweni yangaphambilini yaseNtshonalanga Jalimane kanye neBrithani ngeminyaka yawo-1960, zase zithuthukiswa kakhulu e-United States naseJapan ngeminyaka yawo-1970 kanye nawo-1980 ngokulandelana.NgobaBMC ngobuningi ukubumba compoundszinezakhiwo ezinhle kakhulu zikagesi, izakhiwo zemishini, ukumelana nokushisa, ukumelana nokugqwala kwamakhemikhali, futhi zivumelane nezinqubo ezihlukahlukene zokubumba, zingahlangabezana nezidingo zokusebenza kwemikhiqizo ehlukahlukene, ngakho ziya ngokuya zithandwa ngabasebenzisi.

(1) Izimpawu kanye nokusetshenziswa kwe-BMC

I-BMC inezinto ezinhle zomzimba, zikagesi kanye nemishini, ngakho-ke isetshenziswa kabanzi, njengokwenza izingxenye zemishini ezifana nezingxenye zebhokisi lamagiya, amapayipi okudonsa amanzi, amakhava amavalvu, obhampa nokunye;Ibuye isetshenziswe kabanzi kwezokundiza, izakhiwo, ifenisha,imikhiqizo yenhlanzekonezinye izici ezidinga ukumelana nokuzamazama komhlaba, ukuncipha komlilo, ubuhle nokuqina;Emkhakheni wayo wendabuko kagesi, ukusetshenziswa kwawo kuyanda futhi kubanzi.

(2) Imikhiqizo ejwayelekile

Izingxenye zikagesi (isivikelo, shintsha 29, ibhokisi lamamitha,igobolondo le-circuit breaker, ibhulokhi yetheminali, amagobolondo omkhiqizo asekhaya noma wezohwebo we-electromechanical), izingxenye zemoto (isibonisi samalambu angaphambili, isicabha sangemuva, igobolondo lesipikha, njll.), igobolondo lemitha, igobolondo lempahla yomsindo.

(3) Indlela yokwenza i-BMC

Umshini wokubumba umjovo we-BMC ngokuyinhloko uyinqubo yempahla eyinqwaba ye-BMC, ephoqelelwa emgqonyeni we-BMC ngesiphakeli se-BMC, bese idluliselwa ngaphambili komgqomo ngesikulufu, bese ijova emgodini wokukhunta ukuze uphulukiswe futhi ubunjwe.

I-BMC iyisisetshenziswa se-thermosetting.Izinga lokushisa lombhobho womshini wokubumba umjovo akufanele libe phezulu kakhulu.Ngokuvamile isethwe kumadigri angu-60 ukuze kube lula ukuhamba kwezinto.

Umshini wokubumba umjovo we-BMC ngokuyinhloko uyisisetshenziswa esisebenzayo sokukhiqiza izinto ezibushelelezi ze-thermosetting.Kukhona isethi yesistimu ye-hydraulic engxenyeni yokuphakelayo, ephoqelela izinto ezinezigaxa emgqonyeni lapho isikulufu silindelwe.Umshini wokubumba umjovo we-BMC ulungele isikhunta esinesakhiwo esiyinkimbinkimbi, esicutshungulwa ngokubunjwa komjovo, ngokusebenza kahle komkhiqizo okuphezulu kanye nomfutho ophansi wokusebenza.

Izindlela zokubumba ze-BMC zifaka ukubumba kokucindezelwa, ukubunjwa kokudlulisa kanye nokubumba komjovo.Muva nje, ukubumba umjovo kuyindlela eyinhloko.

① Indlela yokubumba yokuminyanisa, bona indlela yokubumba ye-SMC.

② Dlulisa indlela yokubumba.Izinto ezisetshenziswayo zinohlobo lwebhodwe kanye nohlobo lwepiston olusizayo, ikakhulukazi uhlobo lwepiston olusizayo.
