Le khasiInqubo Yokubumba Ebonakalayo Ye-SMCyiyona esebenza kahle kunazo zonke kwi-Fiber Fiber Fiber Redfored Plastic / Composite Matering Coldenting inqubo. Inqubo yokubumba ye-SMC inezinzuzo eziningi, ezinjengokuthi: Ubukhulu obunembile bomkhiqizo, ukubukeka okuhle komkhiqizo, ukubukeka okuhle komkhiqizo, ukucubungula okubucayi nakho kungavela kwinqubo yokukhiqiza yokubumba ye-SMC, okubonakala ngokukhethekile kulezi zizathu ezilandelayo:
(I)Ukuntuleka kwezinto ezibonakalayo: Ukuntuleka kwezinto ezibonakalayo kusho ukuthi izingxenye ezibunjiweyo ze-SMC azigcwalisiwe ngokuphelele, futhi izindawo zokukhiqiza zigxile kakhulu emaphethelweni emikhiqizo ye-SMC, ikakhulukazi izimpande namagumbi amakhona.
(a) ukukhululwa okuncane kwezinto ezibonakalayo
(b) Izinto ze-SMC zinobunzima obungebuhle
(C) ingcindezi engafanele yempahla
(d) Ukwelapha ngokushesha okukhulu
I-Mechanism New Delignesures:
①-ke impahla ye-SMC ifakwe ngopulasitiki ngokushisa, ukuncibilika ukuncibilika kukhulu. Ngaphambi kokuphendula okuxhumene nokuqina nokuqina kuqediwe, asikho isikhathi esanele, ingcindezi, kanye nevolumu ukugcwalisa umgodi wokulingisa ngokuncibilika.
②) Isikhathi sokugcina sezinto zokubumba ze-SMC zinde kakhulu, futhi i-styrene inamathela kakhulu, okuholela ekunciphiseni okukhulu ezindaweni zokugeleza kwezinto zokubumba ze-SMC.
I-resin paste ayifakwenga ngefayibha. I-resin paste ayikwazi ukushayela i-fiber ukugeleza ngesikhathi sokubumba, okuholela ekutheni kushone ngokwezinto ezibonakalayo. Ukushoda kwezinto zokwakha ezibangelwa yizizathu ezingenhla, ikhambi eliqondile kakhulu ukususa lezi zinto ezibunjiwe lapho usika izinto zokwakha.
Inani lokuphakelayo okwanele libangela ukushoda okubonakalayo. Isixazululo ukukhulisa inani lokudla ngendlela efanele.
Umoya omkhulu kakhulu kanye nento eningi eguquguqukayo ezintweni zokubumba. Isixazululo kufanele sikhuphule inani lama-offorts; ukukhulisa kahle indawo yokudla kanye nokuqhuma isikhathi esithile sokuhlanza isikhunta; kukhulisa ngokufanele ukucindezela kokubumba.
⑥Ingcindezi isephuze kakhulu, futhi izinto ezibunjiwe ziqede ukuxhumanisa nokuqhuma ngaphambi kokugcwalisa umgodi wokulingisa. ⑦ uma izinga lokushisa elibunjiwe liphezulu kakhulu, ukusabela okuxhumanisa nokuvuselela ukusabela kuzothuthuka, ngakho-ke izinga lokushisa kufanele kwehliswe ngokufanele.
(2)Stoma.Kunezimbobo ezincane ezijwayelekile noma ezingajwayelekile ebusweni bomkhiqizo, iningi lazo ezikhiqizwa ezindongeni eziphezulu neziphakathi zomkhiqizo.
I-Mechanism New Delignesures:
①Izinto zokubumba ze-SMC ziqukethe isilinganiso esikhulu somoya kanye nokuqukethwe okuguquguqukayo kukhulu, futhi ukuqeda amandla akubushelelezi; Umphumela wokuqina wezinto ezibonakalayo ze-SMC awumuhle, futhi igesi alikwazi ukudonswa ngempumelelo. Izimbangela ezingenhla zingalawulwa ngempumelelo yinhlanganisela yokwandisa inani lama-vents nokuhlanza isikhunta.
I-Ouding Area ndawo inkulu kakhulu, ukunciphisa ngokufanele indawo yokudla kungalawulwa. Enqubweni yokusebenza yangempela, izici zabantu nazo zingadala i-trachoma. Isibonelo, uma ukucindezela kusesekuseni kakhulu, kungahle kube nzima kakhulu kugesi esongelwe engxenyeni yokubumba ukuze ikhishwe, ibangele amaphutha angaphezulu anjenge-pores ebusweni bomkhiqizo.
(3)I-Warpage ne-Deformation. Isizathu esiyinhloko sokuphulukiswa okungalingani kwendawo yokubumba kanye ne-shrinkage yomkhiqizo ngemuva kokuduma.
I-Mechanism New Delignesures:
Ngesikhathi sokuvuka kwelapha kwe-resin, isakhiwo samakhemikhali siyashintsha, sibangela ukugcwala kwevolumu. Ukufana kokwelashwa kwenza ukuthi umkhiqizo uthambekele ku-warp uye ohlangothini lokuqala lwelapha. Okwesibili, i-caefficient yokwenyuka kwe-thermal yomkhiqizo inkulu kunaleyo isikhunta sensimbi. Lapho umkhiqizo usupholile, inani layo le-shrinkage likhulu likhulu kunendlela yokushisa yendlela yokushisa yendlela eyodwa. Kuze kube manje, izindlela ezilandelayo zamukelwa ukuxazulula inkinga:
Umehluko wokushisa umehluko phakathi kwezikhunta ezingenhla nezingaphansi, bese wenza ukusatshalaliswa kwamazinga okushisa kungathi ngangokunokwenzeka;
②use ukulungiswa kokupholisa ukunciphisa amandla;
Ukwandisa ngokulula ngengcindezi yokubumba, wandise ukuhlanganiswa komkhiqizo, futhi wehlise inani le-shrinkage lomkhiqizo;
④ Khipha isikhathi sokugcina ukushisa isikhathi esifanele ukuze ususe ukucindezela kwangaphakathi.
⑤Ukubeka izilinganiso zokuvuka kwe-shrinkage zezinto ze-SMC.
(4)Ukukhala.Ukuxhaphaza kwe-semicircular ebusweni bomkhiqizo olapha.
I-Mechanism New Delignesures:
Kungenzeka ukuthi lokho okuqukethwe kuphelelwe yithemba, izinga lokushisa lendawo liphezulu kakhulu, noma okuqukethwe okuguquguqukayo kokuqukethwe kukhulu, futhi izicupho zomoya ziphakathi kwamashidi, okwenza ukushefa kwemishini, okwenza ukusheshe kwe-acimincular ngaphezulu komkhiqizo.
(①Usuku lokwandisa ingcindezi yokubumba
(②engisa isikhathi sokulondolozwa kokushisa
(③) Yehlisa izinga lokushisa elibumba.
Qamba indawo engavuleki
(5)Umbala ongaphezulu womkhiqizo awulingani
I-Mechanism New Delignesures:
Ukushisa okubunjiwe akuwona umfaniswano, futhi ingxenye iphakeme kakhulu. Ukushisa okubumba kufanele kulawulwe kahle;
U-②poor fluindity wezinto zokubumba, okuholela ekusatshalalisweni kwe-fiber okungalingani, ngokuvamile kungakhulisa ingcindezi yokubumba ukukhulisa ukuncibilika kokuncibilika;
I-③Igcument kanye ne-resin angeke kuhlanganiswe kahle kwinqubo yokunamathisela kombala okuhlanganisiwe.
