IInqubo yokubumba impahla ye-SMCiyona esebenza kahle kakhulu ku-fiber yengilazi eqiniswe ngepulasitiki/inqubo yokubumba impahla eyinhlanganisela.Inqubo yokubumba ye-SMC inezinzuzo eziningi, njengokuthi: usayizi womkhiqizo onembile, ubuso obushelelezi, ukubukeka komkhiqizo omuhle nokuphindaphinda usayizi, isakhiwo esiyinkimbinkimbi singabuye sibunjwe ngesikhathi esisodwa, ukucubungula kwesibili akudingi ukulimaza umkhiqizo, njll. Nokho, kubi amaphutha azophinde avele enqubweni yokukhiqiza yokubumba ye-SMC, ebonakala kakhulu kulezi zizathu ezilandelayo:
(I)Ukuntula impahla: Ukuntuleka kwezinto kusho ukuthi izingxenye ezibunjiwe ze-SMC azigcwaliswa ngokuphelele, futhi izindawo zokukhiqiza zigxile kakhulu emaphethelweni emikhiqizo ye-SMC, ikakhulukazi izimpande neziqongo zamakhona.
(a) Ukukhishwa kwempahla okuncane
(b) Impahla ye-SMC ayinamanzi amancane
(C) Ukucindezela kwemishini enganele
(d) Ukwelapha ngokushesha kakhulu
Indlela yokukhiqiza kanye nezinyathelo zokuphikisa:
①Ngemva kokuba impahla ye-SMC yenziwe ipulasitiki ngokushisa, i-viscosity encibilikayo inkulu.Ngaphambi kokuba kuqedwe ukuxhumanisa nokuqiniswa kokusabela, asikho isikhathi esanele, ingcindezi, kanye nevolumu yokugcwalisa isikhunta ngokuncibilika.
②) Isikhathi sokugcina sezinto zokubumba ze-SMC side kakhulu, futhi i-styrene iyashintshashintsha kakhulu, okuholela ekwehleni okukhulu kwezakhiwo zokugeleza zezinto zokubumba ze-SMC.
③I-resin paste ayicwiliswe ku-fiber.I-resin paste ayikwazi ukushayela i-fiber ukuthi igeleze ngesikhathi sokubumba, okuholela ekushodeni kwezinto ezibonakalayo.Ngenxa yokuntuleka kwezinto ezibangelwa izizathu ezingenhla, isisombululo esiqondile kakhulu ukususa lezi zinto ezibunjiwe lapho usika izinto.
④Inani lokuphakela elinganele lidala ukushoda kwezinto.Isixazululo ukukhulisa inani lokudla ngendlela efanele.
⑤Kunomoya omningi kanye nezinto eziningi eziguquguqukayo endabeni yokubumba.Isixazululo ukukhulisa ngokufanelekile inani le-exhausts;ukwandisa ngokufanele indawo yokudla kanye ne-burp isikhathi esithile sokuhlanza isikhunta;ukwandisa ngokufanele ingcindezi yokubumba.
⑥Ingcindezi iphuzile kakhulu, futhi okokusebenza okubunjiwe sekuqedile ukuxhumanisa nokulungisa ngaphambi kokugcwalisa isikhunta.⑦ Uma izinga lokushisa lesikhunta liphezulu kakhulu, ukusabela kokuxhumanisa nokuphulukisa kuzoqhubekela phambili, ngakho-ke izinga lokushisa kufanele lehliswe ngokufanelekile.
(2)Stoma.Kukhona izimbobo ezincane ezivamile noma ezingajwayelekile ebusweni bomkhiqizo, eziningi zazo ezikhiqizwa phezulu naphakathi kwezindonga ezincane zomkhiqizo.
Indlela yokukhiqiza kanye nezinyathelo zokuphikisa:
①Into yokubumba ye-SMC iqukethe inani elikhulu lomoya futhi okuqukethwe okuguquguqukayo kukhulu, futhi i-exhaust ayibushelelezi;umphumela wokujiya wezinto ze-SMC awumuhle, futhi igesi ayikwazi ukukhishwa ngokuphumelelayo.Izimbangela ezingenhla zingalawulwa ngokuphumelelayo ngokuhlanganiswa kokwandisa inani lama-vents nokuhlanza isikhunta.
②Indawo yokudla inkulu kakhulu, ukwehlisa ngokufanelekile indawo yokudla kungalawulwa.Enqubweni yokusebenza yangempela, izici zomuntu zingase futhi zibangele i-trachoma.Isibonelo, uma i-pressurization ingaphambi kwesikhathi kakhulu, kungase kube nzima ukuthi igesi esongwe esakhiweni esibunjwayo ikhishwe, okubangele ukonakala okungaphezulu njengezimbotshana ezingaphezulu komkhiqizo.
(3)I-Warpage kanye ne-deformation.Isizathu esiyinhloko ukuphulukiswa okungalingani kwenhlanganisela yokubumba kanye nokuncipha komkhiqizo ngemva kokudilizwa.
Indlela yokukhiqiza kanye nezinyathelo zokuphikisa:
Ngesikhathi sokwelashwa kwe-resin, ukwakheka kwamakhemikhali kuyashintsha, okubangela ukuncipha kwevolumu.Ukufana kokwelapha kwenza umkhiqizo uthande ukusonteka ohlangothini lokuqala olulashiwe.Okwesibili, i-coefficient yokwandisa okushisayo yomkhiqizo inkulu kunesikhunta sensimbi.Uma umkhiqizo upholile, izinga lawo lokushwabana kwendlela eyodwa likhulu kunesilinganiso sokushisa sendlela eyodwa yokuncipha kwesikhunta.Ukuze kufezeke lokhu, kusetshenziswa izindlela ezilandelayo ukuxazulula inkinga:
①Yehlisa umehluko wezinga lokushisa phakathi kwesikhunta esiphezulu nesiphansi, futhi wenze ukusatshalaliswa kwezinga lokushisa kube ngokulingana ngangokunokwenzeka;
②Sebenzisa izinto zokupholisa ukuze ukhawulele ukuguga;
③Khulisa ngokufanelekile ingcindezi yokubumba, ukhuphule ukubumbana kwesakhiwo somkhiqizo, futhi unciphise izinga lokushwabana lomkhiqizo;
④ Yelula isikhathi sokugcina ukushisa ngendlela efanele ukuze kuqedwe ingcindezi yangaphakathi.
⑤Lungisa izinga lokuncipha lokuphulukisa lezinto ze-SMC.
(4)Amabhamuza.I-semicircular iqhuma ebusweni bomkhiqizo olashiwe.
Indlela yokukhiqiza kanye nezinyathelo zokuphikisa:
Kungenzeka ukuthi izinto azilashwanga ngokuphelele, izinga lokushisa lendawo liphezulu kakhulu, noma okuqukethwe okuguquguqukayo kokubalulekile kukhulu, futhi izingibe zomoya phakathi kwamashidi, okwenza i-semicircular iqhume ebusweni bomkhiqizo.
(①Uma ukhuphula ingcindezi yokubumba
(②Nweba isikhathi sokugcina ukushisa
(③) Yehlisa izinga lokushisa lesikhunta.
④Yehlisa indawo yokuqaqa
(5)Umbala ongaphezulu womkhiqizo awulingani
Indlela yokukhiqiza kanye nezinyathelo zokuphikisa:
① Izinga lokushisa lesikhunta alifani, futhi ingxenye iphezulu kakhulu.Ukushisa kwesikhunta kufanele kulawulwe kahle;
②I-fluidity encane yezinto ezibunjwayo, okuholela ekusabalaliseni kwefayibha engalingani, ngokuvamile kungakhuphula ingcindezi yokubumba ukuze kwandiswe ukuncibilika kokuncibilika;
③I-pigment ne-resin ayikwazi ukuxutshwa kahle enqubweni yokuhlanganisa ukunamathisela kombala.
