He aha ke kaha uea?
ʻO ke kaʻina huki uea he kaʻina hana metala. I ka hoʻoili ʻana i ke kaomi metala, hoʻopaʻa ʻia ka metala i loko o ka mold ma lalo o ka hana o ka ikaika o waho, ua hoʻopaʻa ʻia ka ʻāpana cross-sectional metala, a ʻo ke ʻano hana ʻenehana e loaʻa ai ke ʻano cross-sectional a me ka nui i kapa ʻia ke kiʻi uea metala. kaʻina hana.
ʻO ke kaha kiʻi uea kahi ʻano hana e hoʻohana ai i ka neʻe ʻana o ka lole kaha kiʻi e hamo i hope a i waho ma luna o ka ʻili o ka mea hana e hoʻomaikaʻi ai i ka pau ʻana o ka ʻili o ka mea hana. He laina laina ke ʻano o ka ʻili. Hiki iā ia ke hoʻomaikaʻi i ka maikaʻi o ka ʻili a uhi i nā ʻōpala liʻiliʻi.
ʻO ka ʻili o ka pā metala nā hiʻohiʻona o ka anti-rust, anti-oxidation, anti-scratch, anti-chemical agent a me anti-smoke. Ma ke ʻano o ka hiʻohiʻona, ma muli o ka ʻālohilohi kūikawā o ka huahana ponoʻī, i mea e pale ʻole ai i ka palahu ma muli o ka friction, ua ʻōlelo ʻia e hoʻohana iā ia ma kahi ākea me ka liʻiliʻi liʻiliʻi, a i ʻole kahi ākea ākea. Eia kekahi, ua ʻōlelo ʻia e hoʻohana ma kahi maloʻo, a i ʻole kahi e pulu pinepine ʻole ai ka haʻahaʻa haʻahaʻa, i mea e mālama ai i ka paʻa o ka huahana. Hiki ke uhi pono i ka palaki ili metala ke uhi pono i na laina mechanical a me na hemahema o ka hana.
Loaʻa iā mākou nā ʻenehana kaha kiʻi uea maikaʻi, a loaʻa iā mākou nā mīkini huki uea e hana i nā uea metala. Nui nā mea kūʻai e like me mākou. ʻO ia mau huahana he gula i kāhili ʻia, kala ʻia i ke kālā, ke one snowflake, a me nā ʻili one, hiki ke hōʻike piha i ka manaʻo metala kaumaha o ke gula, kālā, etc.
