Katerangan produksi
HDG umumna nujul kana hot-dip galvanizing. Hot-dip galvanizing nyaéta sangkan logam molten meta jeung matrix beusi pikeun ngahasilkeun hiji lapisan alloy, ku kituna matrix jeung palapis nu digabungkeun. Hot-dip galvanizing nyaéta pikeun acar bagian beusi sareng baja heula, pikeun ngaleungitkeun oksida beusi dina permukaan bagian beusi sareng baja, saatos acar, éta dibersihkeun dina tank amonium klorida atanapi larutan cai séng klorida atanapi a solusi cai dicampur tina amonium klorida jeung séng klorida, lajeng dikirim ka tank palapis hot dip. Hot-dip galvanizing boga kaunggulan palapis seragam, adhesion kuat sarta hirup layanan panjang.
The countersunk sirah tina hot dip galvanized bolts biasana dipaké dimana sambungan anu diperlukeun. Ieu mangrupakeun bagian non-standar dina bentuk U sahingga ogé katelah U-baud. Hot-dip galvanized bolts kalawan threads dina duanana tungtung bisa dipaké dina kombinasi kalayan kacang. Modél utiliti utamana dipaké pikeun ngalereskeun objék tubular atanapi flaky.
Résistansi korosi utamana ditangtukeun ku ketebalan lapisan galvanized, jadi pangukuran ketebalan mindeng jadi dadasar utama pikeun ditilik kualitas lapisan galvanized. Sudut sareng laju solusi ogé gaduh pangaruh anu ageung. Ku alatan éta, praktis teu mungkin pikeun ménta ketebalan palapis lengkep seragam.
