沈陽長春彩鋼卷

    我先觀察彩鋼板外露鋼(gang)(gang)材(cai)如斷面(mian)等(deng)是(shi)(shi)否結晶(jing)細密(mi)，是(shi)(shi)否發(fa)灰、發(fa)暗和(he)雜質(zhi)(zhi)。若切面(mian)是(shi)(shi)結晶(jing)細密(mi)型的(de)(de)(de)則(ze)是(shi)(shi)質(zhi)(zhi)量比較優越的(de)(de)(de)。我(wo)們首先得考(kao)慮基板(ban)(ban)(ban)(ban)(ban)(ban)和(he)腹(fu)(fu)(fu)膜(mo)(mo)鍍(du)(du)層的(de)(de)(de)厚(hou)度，比較好的(de)(de)(de)彩(cai)(cai)鋼(gang)(gang)板(ban)(ban)(ban)(ban)(ban)(ban)基板(ban)(ban)(ban)(ban)(ban)(ban)是(shi)(shi)0.02~0.05mm，覆膜(mo)(mo)或(huo)者(zhe)(zhe)涂層厚(hou)度往往只有(you)0.15mm以下。 觀察(cha)基板(ban)(ban)(ban)(ban)(ban)(ban)厚(hou)度和(he)覆膜(mo)(mo)的(de)(de)(de)厚(hou)度，彩(cai)(cai)鋼(gang)(gang)板(ban)(ban)(ban)(ban)(ban)(ban)是(shi)(shi)有(you)基板(ban)(ban)(ban)(ban)(ban)(ban)和(he)彩(cai)(cai)色的(de)(de)(de)腹(fu)(fu)(fu)膜(mo)(mo)或(huo)者(zhe)(zhe)鍍(du)(du)層構成的(de)(de)(de)。聽聲(sheng)音用(yong)手(shou)指或(huo)用(yong)硬物敲(qiao)擊彩(cai)(cai)鋼(gang)(gang)板(ban)(ban)(ban)(ban)(ban)(ban)，彩(cai)(cai)鋼(gang)(gang)板(ban)(ban)(ban)(ban)(ban)(ban)的(de)(de)(de)材(cai)質(zhi)(zhi)如果(guo)較差，則(ze)發(fa)出來的(de)(de)(de)聲(sheng)音是(shi)(shi)悶的(de)(de)(de)，金(jin)屬聲(sheng)音不明顯，材(cai)質(zhi)(zhi)較好的(de)(de)(de)彩(cai)(cai)鋼(gang)(gang)板(ban)(ban)(ban)(ban)(ban)(ban)金(jin)屬聲(sheng)音是(shi)(shi)比較響亮、清脆的(de)(de)(de)。觀察(cha)彩(cai)(cai)鋼(gang)(gang)板(ban)(ban)(ban)(ban)(ban)(ban)的(de)(de)(de)外漏邊緣(yuan)，拿到一塊彩(cai)(cai)鋼(gang)(gang)板(ban)(ban)(ban)(ban)(ban)(ban)，因(yin)為從影響彩(cai)(cai)鋼(gang)(gang)板(ban)(ban)(ban)(ban)(ban)(ban)的(de)(de)(de)使用(yong)時間來看，基板(ban)(ban)(ban)(ban)(ban)(ban)的(de)(de)(de)厚(hou)度是(shi)(shi)很重要的(de)(de)(de)。而有(you)些生產(chan)彩(cai)(cai)鋼(gang)(gang)板(ban)(ban)(ban)(ban)(ban)(ban)的(de)(de)(de)廠家(jia)往往在(zai)基板(ban)(ban)(ban)(ban)(ban)(ban)及彩(cai)(cai)鋼(gang)(gang)板(ban)(ban)(ban)(ban)(ban)(ban)涂層或(huo)覆膜(mo)(mo)上做(zuo)手(shou)腳，他們降(jiang)低基板(ban)(ban)(ban)(ban)(ban)(ban)的(de)(de)(de)厚(hou)度，但是(shi)(shi)增加腹(fu)(fu)(fu)膜(mo)(mo)的(de)(de)(de)厚(hou)度來降(jiang)低彩(cai)(cai)鋼(gang)(gang)板(ban)(ban)(ban)(ban)(ban)(ban)的(de)(de)(de)生產(chan)成本(ben)，這(zhe)就大大降(jiang)低了(le)彩(cai)(cai)鋼(gang)(gang)板(ban)(ban)(ban)(ban)(ban)(ban)的(de)(de)(de)使用(yong)壽命了(le)。
