BMC (DMC) imathiriyeli sisishunqulelo sobuninzi (intlama) yokubumba iikhompawundi, oko kukuthi, iikhompawundi zokubumba isambuku.Idla ngokubizwa ngokuba yikhompawundi yokubumba iqela lepolyester engafakwanga eTshayina.Izixhobo zayo eziphambili zi-mass prepregs ezenziwe nge-GF (i-fiber yeglasi enqunqiweyo), phezulu (i-resin unsaturated), i-MD (i-filler calcium carbonate) kunye neentlobo ezahlukeneyo zokudibanisa.Imathiriyeli ye-BMC yaqala ukusetyenziswa kwindawo eyayisakuba yiNtshona Jamani naseBritani ngeminyaka yoo-1960, emva koko yaphuhliswa kakhulu e-United States nase-Japan ngeminyaka yoo-1970 noo-1980 ngokulandelelanayo.NgokubaIikhompawundi zokubumba isambuku ze-BMCzineempawu ezibalaseleyo zombane, iipropathi zoomatshini, ukuxhathisa ubushushu, ukuxhathisa ukubola kweekhemikhali, kwaye zilungelelanise neenkqubo ezahlukeneyo zokubumba, zinokuhlangabezana neemfuno zokusebenza kweemveliso ezahlukeneyo, ngoko zithandwa ngakumbi nabasebenzisi.
(1) Iimpawu kunye nokusetyenziswa kwe-BMC
I-BMC ineempawu ezilungileyo zomzimba, zombane kunye nezoomatshini, ngoko ke isetyenziswa kakhulu, njengokwenza amalungu omatshini anje ngezixhobo zebhokisi yegiya, imibhobho yokungena, izigqubuthelo zevalvu, iibhampa njalo njalo;Ikwasetyenziswa ngokubanzi kwinqwelomoya, ulwakhiwo, ifenitshala,iimveliso zococekokunye neminye imiba efuna ukuxhathisa inyikima, ukunqanda amadangatye, ubuhle kunye nokuqina;Kwintsimi yayo yombane yendabuko, ukusetyenziswa kwayo kuninzi kwaye kubanzi.
(2) Iimveliso eziqhelekileyo
Amalungu ombane (i-insulator, tshintsha 29, ibhokisi yeemitha,iqokobhe lomqhekezi wesekethe, ibhloko ye-terminal, iigobolondo ezahlukeneyo zemveliso ye-electromechanical yasekhaya okanye yorhwebo), iinxalenye zemoto (i-reflector ye-headlight, ucango lwangemva, iqokobhe lesithethi, njl.), iqokobhe lemitha, iqokobhe lesixhobo sesandi.
(3) Indlela yokwenza i-BMC
Umatshini wokubumba inaliti ye-BMC yinkqubo ye-BMC yobuninzi bezinto, enyanzeliswa kwi-BMC kwi-barrel nge-BMC feeder, emva koko idluliselwe phambi kombhobho nge-screw, kwaye emva koko ifakwe kwi-mold cavity ukunyanga kunye nokubumba.
I-BMC yimathiriyeli ye-thermosetting.Ubushushu bombhobho womatshini wokubumba umjovo akufanele ube phezulu kakhulu.Ngokuqhelekileyo ibekwe kwii-degrees ze-60 ukuququzelela ukuhamba kwezinto.
Umatshini wokubumba inaliti ye-BMC sisixhobo sobuchwephesha sokuvelisa imathiriyeli ye-thermosetting lumpy.Kukho isethi ye-hydraulic system kwindawo yokutya, nto leyo inyanzelisa izinto ezinamaqhuma kwi-barrel xa i-screw ilindeleke.Umatshini wokubumba inaliti ye-BMC ilungele ukubumba kunye nesakhiwo esintsonkothileyo, esenziwe ngokubumba inaliti, kunye nokusebenza kakuhle kwemveliso kunye noxinzelelo lwabasebenzi oluphantsi.
Iindlela zokubumba ze-BMC ziquka ukubunjwa koxinzelelo, ukubunjwa kokudluliselwa kunye nokubumba inaliti.Kutshanje, ukubumba inaliti yeyona ndlela iphambili.
① Indlela yokubumba ucinezelo, bona indlela yokubumba i-SMC.
② Ukutshintshela indlela yokubumba.Isixhobo sinohlobo lwembiza kunye nohlobo lwepiston oluncedisayo, ikakhulu uhlobo lwepiston oluncedisayo.
