Ma muli o ka hoʻohana ʻia ʻana o ka pā hui i loko o kahi wahi haʻahaʻa, hiki mai ka ʻōpala a me ka corrosion.Pehea ka lōʻihi e hiki ai ke hoʻohana ma ka laulā?

ʻO ka mea o ka hana ʻana i ka pā kula a me ka pā pipi maʻamau loaʻa i ka uea uʻi uila, uea wela wela, uea kila Galfan i uhi ʻia, 10% alumini zinc alloy uea a me ke ʻano hou o selenium chromium steel wire. He ʻokoʻa loa nā waiwai anti-corrosion o kēia mau mea. , aʻaʻole like ke ola o ka lawelawe. Heʻokoʻa loa nā mea anti-corrosion o kēia mau mea, aʻaʻole like ke ola lawelawe.

Cold galvanized hinge ami kahua pa i ikeia e like me electroplating, galvanized liʻiliʻi, ua rust, akā, ke kumu kūʻai mea cheap, ke ola lawelawe i loko o 5-6 years.The lawelawe ola o wela dip galvanizing mea e pili ana i 20-60 makahiki, a me kona corrosion kū'ē. he laulā.ʻO ka plastic i uhi ʻia ʻo PVC he papa o ka ʻeleʻele ʻōmaʻomaʻo a i ʻole hina-ʻulaʻula ʻulaʻula ma luna o ka uea kila galvanized mua e pale ai i ka ʻino ʻana o ke anawaena uea, kahi kūpono e hoʻomaikaʻi ai i ka hana anti-corrosive a me ka ʻōpala..

Me ka hoʻomaikaʻi ʻana i ka ʻenehana anti-corrosion o ka ʻupena pā pipi, e hoʻomaikaʻi ʻia ka hana uea kila o ka ʻupena pā pipi, i mea e hoʻomaikaʻi ai i ke ola lawelawe he kōkua nui. ʻO ka manawa lawelawe ka mea nui ma muli o ka hoʻohana ʻana o ka ʻO ke kaiapuni a me ka hana o ke kūkulu ʻana i kēlā manawa he maʻamau, hoʻomaikaʻi i ka hana o nā kūlana hana hiki ke hoʻonui i ka manawa o ka lawelawe.
