Hoʻohu wela I-beam
ʻO ka wehewehe pōkole:
Ua kapa ʻia ʻo I-beam hot dip galvanized I-beam a i ʻole hot-dip galvanized I-beam.ʻO ia ka hoʻokomo ʻana i ka I-beam derusted i loko o ka zinc hehee ma kahi o 500 ℃, i hoʻopili ʻia ka papa zinc i ka ʻili o ka I-beam, i mea e hoʻokō ai i ke kumu o ka anti-corrosion.He kūpono ia no nā ʻano kaiapuni corrosive ikaika e like me ka waikawa ikaika a me ka noe alkali.
Nā mea maikaʻi o ka huahana
1. ʻO ke kumu kūʻai haʻahaʻa haʻahaʻa: ʻoi aku ka haʻahaʻa o ke kumu kūʻai o ka galvanizing wela a me ka pale ʻana i ka ʻōpala ma mua o nā mea pena ʻē aʻe;
2. Paʻa: ʻo ke kila wela ka galvanized angle he mau hiʻohiʻona o ka ʻālohilohi o ka ʻili, ka papa zinc like ʻole, ʻaʻohe plating i nalowale, ʻaʻohe kulu, adhesion ikaika a me ke kūpaʻa ʻana i ka corrosion ikaika.I loko o ke kaona o ke kaona, hiki ke mālama ʻia ka mānoanoa antirust hot-dip galvanized ma mua o 50 mau makahiki me ka hoʻoponopono ʻole;Ma nā kūlanakauhale a i ʻole nā wahi ʻē aʻe, hiki ke mālama ʻia ka pale antirust hot-dip galvanized maʻamau no 20 mau makahiki me ka hoʻoponopono ʻole;
3. ʻO ka hilinaʻi maikaʻi: ua hui pū ʻia ka zinc coating a me ke kila a lilo i ʻāpana o ka ʻili kila, no laila ʻoi aku ka hilinaʻi o ka paʻa;
4. ʻO ka paʻakikī ikaika o ka uhi: hoʻokumu ka zinc coating i kahi hoʻolālā metallurgical kūikawā, hiki ke pale i ka pōʻino mechanical i ka wā o ka laweʻana a me ka hoʻohanaʻana;
5. Palekana piha: hiki ke uhi ʻia kēlā me kēia ʻāpana o nā ʻāpana i hoʻopaʻa ʻia me ka zinc, a hiki ke pale pono ʻia i loko o nā poho, nā kihi ʻoi a me nā wahi huna;
6. Hoʻopakele manawa a me ka mālama hana: ʻoi aku ka wikiwiki o ke kaʻina hana galvanizing ma mua o nā ʻano hana hana uhi ʻē aʻe, a hiki ke pale ʻia ka manawa e pono ai no ka pena ʻana ma ka pūnaewele ma hope o ke kau ʻana.
