IInqubo yokubumba izinto ze-SMCiyona esebenza kahle kakhulu enqubweni yokubumba ipulasitiki/izinto ezihlanganisiwe zefayibha yengilazi. Inqubo yokubumba i-SMC inezinzuzo eziningi, njenge: usayizi womkhiqizo onembile, indawo ebushelelezi, ukubukeka okuhle komkhiqizo kanye nosayizi ophindaphindwayo, isakhiwo esiyinkimbinkimbi singabunjwa ngesikhathi esisodwa, ukucubungula kwesibili akudingeki kulimaze umkhiqizo, njll. Kodwa-ke, amaphutha amabi azovela nasenqubweni yokukhiqizwa kokubumba i-SMC, okubonakala kakhulu kulezi zizathu ezilandelayo:
(Mina)Ukuntuleka kwezinto ezibonakalayoUkuntuleka kwezinto kusho ukuthi izingxenye ezibunjiwe ze-SMC azigcwali ngokuphelele, futhi izindawo zokukhiqiza zigxile kakhulu emaphethelweni emikhiqizo ye-SMC, ikakhulukazi izimpande kanye nezingxenye eziphezulu zamakhona.
(a) Ukukhishwa kwezinto ezincane
(b) Izinto ze-SMC azinamanzi kahle
(C) Umfutho wemishini onganele
(d) Ukwelapha ngokushesha okukhulu
Indlela yokukhiqiza kanye nezinyathelo zokumelana nayo:
①Ngemva kokuba izinto ze-SMC sezifakwe ipulasitiki ngokushisa, i-viscosity yokuncibilika iba nkulu. Ngaphambi kokuba kuqedwe ukusabela kokuxhumanisa nokuqina, asikho isikhathi esanele, ingcindezi, kanye nomthamo wokugcwalisa umgodi wesikhunta ngokuncibilika.
②) Isikhathi sokugcina sezinto zokubumba ze-SMC side kakhulu, futhi i-styrene iyaguquguquka kakhulu, okuholela ekunciphiseni okukhulu kwezakhiwo zokugeleza kwezinto zokubumba ze-SMC.
③I-resin paste ayifakwanga ku-fiber. I-resin paste ayikwazi ukuqhuba i-fiber ukuthi igeleze ngesikhathi sokubumba, okuholela ekuswelekeni kwezinto. Ngenxa yokuntuleka kwezinto ezibangelwa yizizathu ezingenhla, ikhambi eliqondile kakhulu ukususa lezi zinto ezibunjiwe lapho usika izinto.
④Inani elanele lokudla libangela ukushoda kwezinto zokwakha. Isixazululo ukwandisa inani lokudla ngendlela efanele.
⑤Kunomoya omningi kakhulu kanye nezinto eziningi eziguquguqukayo ezintweni zokubumba. Isixazululo ukwandisa inani lama-exhaust ngendlela efanele; ukwandisa indawo yokudla ngokufanele kanye nokubhoboza isikhathi esithile ukuze kuhlanzwe isikhunta; ukwandisa ngokufanele ingcindezi yokubumba.
⑥Ingcindezi isiphuze kakhulu, futhi izinto ezibunjiwe seziqedile ukuxhumanisa nokulungisa ngaphambi kokugcwalisa umgodi wesikhunta. ⑦Uma izinga lokushisa lesikhunta liphezulu kakhulu, ukusabela kokuxhumanisa nokulungisa kuzoqhubeka, ngakho izinga lokushisa kufanele lehliswe ngokufanele.
(2)I-Stoma.Kunezimbobo ezincane ezijwayelekile noma ezingajwayelekile ebusweni bomkhiqizo, eziningi zazo ezikhiqizwa odongeni oluncane oluphezulu noluphakathi lomkhiqizo.
Indlela yokukhiqiza kanye nezinyathelo zokumelana nayo:
①Izinto zokubumba ze-SMC ziqukethe umoya omningi futhi okuqukethwe okuguquguqukayo kukhulu, kanti ukukhishwa komoya akubushelelezi; umphumela wokujiya kwezinto ze-SMC awumuhle, futhi igesi ayikwazi ukuxoshwa ngempumelelo. Izimbangela ezingenhla zingalawulwa ngempumelelo ngokuhlanganiswa kokwandisa inani lezindawo zokungenisa umoya nokuhlanza isikhunta.
②Indawo yokondla inkulu kakhulu, ukunciphisa indawo yokondla kungalawulwa ngendlela efanele. Enqubweni yokusebenza kwangempela, izici zabantu nazo zingase zibangele i-trachoma. Isibonelo, uma ukucindezela kusenesikhathi, kungaba nzima ukuthi igesi egoqwe ekwakhiweni kokubumba ikhishwe, okuholela ezifweni zobuso ezifana nezimbobo ebusweni bomkhiqizo.
(3)I-Warpage kanye nokuguqulwaIsizathu esiyinhloko ukungaguquguquki kokwakheka kwe-molding kanye nokuncishiswa komkhiqizo ngemva kokudilizwa.
Indlela yokukhiqiza kanye nezinyathelo zokumelana nayo:
Ngesikhathi sokusabela kokwelapha kwe-resin, isakhiwo samakhemikhali siyashintsha, okubangela ukuncipha kwevolumu. Ukufana kokwelapha kwenza umkhiqizo uthambekele ekugobeni ohlangothini lokuqala olupholile. Okwesibili, i-coefficient yokwandisa ukushisa komkhiqizo inkulu kuneyesikhunta sensimbi. Lapho umkhiqizo upholile, izinga lawo lokuncipha kwendlela eyodwa likhulu kunezinga lokuncipha kokushisa kwendlela eyodwa yesikhunta. Kulokhu, kusetshenziswa izindlela ezilandelayo ukuxazulula inkinga:
①Nciphisa umehluko wokushisa phakathi kwesikhunta esingaphezulu nesingaphansi, bese wenza ukusatshalaliswa kokushisa kube ngokulinganayo ngangokunokwenzeka;
②Sebenzisa izinto zokupholisa ukuze unciphise ukuguguleka;
③Khulisa ngokufanele ingcindezi yokubumba, wandise ukuqina kwesakhiwo somkhiqizo, futhi wehlise izinga lokuncishiswa komkhiqizo;
④ Nweba isikhathi sokulondoloza ukushisa ngendlela efanele ukuze uqede ukucindezeleka kwangaphakathi.
⑤Lungisa izinga lokuncishiswa kokuqina kwezinto ze-SMC.
(4)Ukuqhumisa.Ukuvuvukala okungenasiyingi ebusweni bomkhiqizo osuqediwe.
Indlela yokukhiqiza kanye nezinyathelo zokumelana nayo:
Kungenzeka ukuthi into ayipheli ngokuphelele, izinga lokushisa lendawo liphezulu kakhulu, noma okuqukethwe okuguquguqukayo kwento kukhulu, futhi umoya ubamba phakathi kwamashidi, okwenza ukukhukhumala okungama-semicircular ebusweni bomkhiqizo.
(①Uma ukhulisa ingcindezi yokubumba
(②Nweba isikhathi sokulondoloza ukushisa
(③) Yehlisa izinga lokushisa lesikhunta.
④Nciphisa indawo yokuphumula
(5)Umbala womphezulu womkhiqizo awulingani
Indlela yokukhiqiza kanye nezinyathelo zokumelana nayo:
①Izinga lokushisa lesikhunta alifani, futhi ingxenye iphakeme kakhulu. Izinga lokushisa lesikhunta kufanele lilawulwe kahle;
②Ukugeleza okuncane kwezinto zokubumba, okuholela ekusabalaleni kwefayibha okungalingani, ngokuvamile kungandisa ingcindezi yokubumba ukuze kwandiswe ukugeleza kokuncibilika;
③Umbala kanye ne-resin akukwazi ukuhlanganiswa kahle enqubweni yokuxuba umbala we-paste.
