IInkqubo yokubumba izinto ze-SMCyeyona isebenzayo kwinkqubo yokubumba iplastiki/izinto ezidityanisiweyo zeglasi. Inkqubo yokubumba i-SMC ineenzuzo ezininzi, ezinje: ubungakanani bemveliso obuchanekileyo, umphezulu ogudileyo, imbonakalo entle yemveliso kunye nobukhulu obuphindaphindwayo, isakhiwo esintsonkothileyo sinokubunjwa ngaxeshanye, ukucutshungulwa kwesibini akufuneki konakalise imveliso, njl. Nangona kunjalo, iziphene ezimbi ziya kubonakala nakwinkqubo yokuvelisa ukubumba i-SMC, ezibonakala kakhulu kwezi zizathu zilandelayo:
(Ndi)Ukunqongophala kwezinto eziphathekayoUkungabikho kwezinto ezisetyenzisiweyo kuthetha ukuba iindawo ezibunjiweyo ze-SMC azizaliswanga ngokupheleleyo, kwaye iindawo zemveliso zigxile kakhulu emaphethelweni eemveliso ze-SMC, ingakumbi iingcambu kunye neencopho zeekona.
(a) Ukukhupha izinto ezincinci
(b) Izinto ze-SMC azikwazi ukuhamba kakuhle
(C) Uxinzelelo olunganelanga lwezixhobo
(d) Ukunyanga ngokukhawuleza kakhulu
Indlela yokuvelisa kunye neendlela zokuchasana:
①Emva kokuba izinto ze-SMC zenziwe iplastiki bubushushu, i-melt viscosity inkulu. Ngaphambi kokuba kugqitywe i-cross-linking kunye ne-solidification reaction, akukho xesha laneleyo, uxinzelelo, kunye nomthamo wokugcwalisa umngxuma we-mold nge-melt.
②) Ixesha lokugcina izinto zokubumba ze-SMC lide kakhulu, kwaye i-styrene iyaguquguquka kakhulu, nto leyo ebangela ukwehla okukhulu kweempawu zokuhamba kwezinto zokubumba ze-SMC.
③Intlama yeresin ayifakwanga kwifayibha. Intlama yeresin ayinakuyiqhuba ifayibha ukuba ihambe ngexesha lokubumba, nto leyo ebangela ukunqongophala kwezinto. Ngenxa yokunqongophala kwezinto ezibangelwa zezi zizathu zingasentla, isisombululo esithe ngqo kukususa ezi zinto zibunjiweyo xa kusikwa izinto.
④Ukutya okunganelanga kubangela ukunqongophala kwezinto ezifunekayo. Isisombululo kukunyusa ukutya ngendlela efanelekileyo.
⑤Kukho umoya omninzi kakhulu kunye nezinto ezininzi eziguquguqukayo kwizinto zokubumba. Isisombululo kukunyusa ngokufanelekileyo inani lee-exhaust; ukwandisa ngokufanelekileyo indawo yokutya kunye nokubhoboza ixesha elithile ukuze kucoceke isikhunta; ukwandisa ngokufanelekileyo uxinzelelo lokubumba.
⑥Uxinzelelo luphelile, kwaye izinto ezibunjiweyo zigqibile ukudibanisa nokulungisa ngaphambi kokuba zizalise umngxuma wesikhunta. ⑦Ukuba ubushushu besikhunta buphezulu kakhulu, impendulo yokudibanisa nokulungisa iya kuqhubeka, ngoko ke ubushushu kufuneka buncitshiswe ngokufanelekileyo.
(2)I-Stoma.Kukho imingxunya emincinci eqhelekileyo okanye engangqalanga kumphezulu wemveliso, uninzi lwayo lwenziwa eludongeni oluncinci oluphezulu noluphakathi lwemveliso.
Indlela yokuvelisa kunye neendlela zokuchasana:
①Izinto zokubumba ze-SMC zinomoya omninzi kwaye umxholo oguquguqukayo mkhulu, kwaye ukukhupha umoya akugudi; isiphumo sokuqina kwezinto ze-SMC asilunganga, kwaye igesi ayinakukhutshelwa ngaphandle ngempumelelo. Ezi zizathu zingasentla zinokulawulwa ngempumelelo ngokudibanisa inani lee-vents kunye nokucoca isikhunta.
②Indawo yokutya inkulu kakhulu, ukunciphisa ngokufanelekileyo indawo yokutya kunokulawulwa. Kwinkqubo yokusebenza yokwenyani, izinto ezibangela umntu nazo zinokubangela i-trachoma. Umzekelo, ukuba uxinzelelo lusekutsha kakhulu, kunokuba nzima ukuba igesi egqunywe kwi-molding compound ikhutshwe, nto leyo ebangela iziphene zomphezulu ezifana neembobo kumphezulu wemveliso.
(3)I-Warpage kunye nokuguqulwaIsizathu esiphambili kukungaguquguquki komxube wokubumba kunye nokuncipha kwemveliso emva kokudilizwa.
Indlela yokuvelisa kunye neendlela zokuchasana:
Ngexesha lokusabela kokuphilisa kwe-resin, ulwakhiwo lweekhemikhali luyatshintsha, nto leyo ebangela ukuncipha komthamo. Ukufana kokuphilisa kwenza imveliso ithambekele ekugobeni kwicala lokuqala eliphilisiweyo. Okwesibini, i-coefficient yokwandisa ubushushu bemveliso inkulu kuneyohlobo lwesinyithi. Xa imveliso ipholile, izinga layo lokuncitshiswa kwendlela enye likhulu kunezinga lokuncitshiswa kobushushu kwendlela enye yohlobo lwesinyithi. Ngenxa yoku, iindlela ezilandelayo ziyasetyenziswa ukusombulula ingxaki:
①Nciphisa umahluko wobushushu phakathi kweenkuni eziphezulu nezisezantsi, kwaye wenze usasazo lobushushu lulingane kangangoko kunokwenzeka;
②Sebenzisa izixhobo zokupholisa ukunciphisa ukuguguleka;
③Nyusa ngokufanelekileyo uxinzelelo lokubumba, yonyusa ubume bemveliso, kwaye yehlise izinga lokuncipha kwemveliso;
④ Yandisa ixesha lokugcina ubushushu ngokufanelekileyo ukuze kuncitshiswe uxinzelelo lwangaphakathi.
⑤Lungisa izinga lokuncitshiswa kwezixhobo ze-SMC.
(4)Ukuqhushumba.Ukudumba okuncinci kumphezulu wemveliso ecociweyo.
Indlela yokuvelisa kunye neendlela zokuchasana:
Kusenokwenzeka ukuba izinto azikapheli ngokupheleleyo, ubushushu bendawo buphezulu kakhulu, okanye umxholo oguquguqukayo kwizinto mkhulu, kwaye umoya ubamba phakathi kwamaphepha, nto leyo eyenza ukuba i-semicircular bulge kumphezulu wemveliso ikhule.
(①Xa unyusa uxinzelelo lokubumba
(②Yandisa ixesha lokugcina ubushushu
(③) Yehlisa ubushushu bokubumba.
④Nciphisa indawo yokuphumla
(5)Umbala womphezulu wemveliso awulingani
Indlela yokuvelisa kunye neendlela zokuchasana:
①Ubushushu bokubumba abufani, kwaye inxalenye iphezulu kakhulu. Ubushushu bokubumba bufanele bulawulwe ngokufanelekileyo;
②Ukungaguquguquki kakuhle kwezinto zokubumba, okubangela ukusasazwa kwefayibha engalinganiyo, ngokubanzi kunokunyusa uxinzelelo lokubumba ukuze kwandiswe ukuguquguquka kokunyibilika;
③Umbala kunye ne-resin azinakuxutywa kakuhle kwinkqubo yokudibanisa intlama yombala.
