Kodi nkhungu yapulasitiki imapangidwa ndi zinthu ziti?
Pulasitiki nkhungu ndi chida chofunikira popanga zinthu zosiyanasiyana zamapulasitiki, zomwe zimagwiritsidwa ntchito pamagalimoto, zida zam'nyumba, zamagetsi ndi mafakitale ena.Pali mitundu yambiri ya zinthu zopangidwa ndi nkhungu za pulasitiki, zida zosiyanasiyana zimakhala ndi katundu ndi ntchito zosiyanasiyana, zotsatirazi ndi zida zingapo wamba:
(1) Aluminiyamu aloyi zinthu
Aluminiyamu alloy nkhungu amagwiritsidwa ntchito popanga magulu ang'onoang'ono kapena zinthu zomwe zimafunikira kupanga mwachangu.Nkhaniyi imakhala ndi matenthedwe abwino, omwe amatha kufulumizitsa kupanga, komanso kukhala ndi dzimbiri komanso kukana kuvala.Aluminiyamu aloyi nkhungu zambiri zosavuta kukonza kuposa zipangizo zina, ndalama kwambiri, ndipo akhoza makonda makonda kuti kupanga.
(2) Chitsulo wamba
Chitsulo wamba ndi nkhungu yotsika mtengo yomwe imayenera kupanga magawo osavuta, otsika kwambiri.Zitsulo zachitsulo zodziwika bwino nthawi zambiri zimapangidwa ndi zitsulo za 45, 50 zitsulo, S45C, S50C, etc. Ngakhale kuti mphamvu ya nkhaniyi sipamwamba, koma chifukwa cha mtengo wake wotsika mtengo, imagwiritsidwa ntchito kwambiri popanga nkhungu, makamaka muzitsulo zazing'ono. otsika amatha kuumba ndi moyo waufupi nkhungu.
(3) Kunyamula zitsulo
Kunyamula zitsulo kumakhala ndi kulimba kwabwino komanso kukana kuvala, ndipo ndi chimodzi mwazosankha zazinthu zapamwamba za nkhungu.Zitsulo zokhala ndi zitsulo zodziwika bwino zimaphatikizapo GCr15, SUJ2, etc., zomwe zitha kugwiritsidwa ntchito popanga nkhungu zazikulu zapakatikati komanso zothamanga kwambiri, monga zida zamagalimoto.
(4) Chitsulo chosapanga dzimbiri
Chitsulo chosapanga dzimbiri chimakhala ndi kukana kwa okosijeni wabwino kwambiri, kukana kwa dzimbiri komanso kulimba, zomwe zimapangitsa kuti nthawi zambiri zigwiritsidwe ntchito popanga makina odzaza chakudya, zida zamankhwala ndi zida zapulasitiki zomwe zimafunidwa kwambiri.Nthambi zachitsulo zosapanga dzimbiri nthawi zambiri zimapangidwa ndi zinthu monga SUS304 kapena SUS420J2, zomwe ndizofunikira makamaka popanga zinthu zapamwamba kwambiri.
(5) Engineering zipangizo pulasitiki
Mapulasitiki aumisiri ndi mtundu watsopano wazinthu zolimba kwambiri za nkhungu zokhala ndi mphamvu zoponya mwamphamvu komanso magwiridwe antchito abwino kwambiri popanga nkhungu zapulasitiki.Mapulasitiki omwe amagwiritsidwa ntchito kwambiri ndi nayiloni (PA), polyimide (PI), aramid (PPS) ndi zina zotero.Mapulasitikiwa ali ndi kukana kutentha kwambiri, mphamvu zambiri komanso kukana mankhwala abwino kwambiri, ndipo ndi oyenera kupanga nkhungu zapamwamba zapulasitiki.
Tiyenera kukumbukira kuti ngakhale chitsanzo chomwecho, chifukwa cha zosankha zakuthupi zosiyanasiyana pali kusiyana kwakukulu, mtengo wankhungu pulasitiki, moyo wautumiki, magwiridwe antchito ndi magawo ena amasiyananso kwambiri.Choncho, posankha zipangizo za nkhungu za pulasitiki ziyenera kufufuzidwa mosamala malinga ndi momwe zimagwirira ntchito, kuchuluka kwa ntchito ndi zizindikiro zodalirika, kuti zitsimikizire kusankha zipangizo zoyenera nkhungu.
