大連長春彩鋼卷

    我先觀察彩鋼板外(wai)露鋼(gang)(gang)(gang)材如(ru)斷面(mian)等是(shi)(shi)否結晶細密，是(shi)(shi)否發灰(hui)、發暗和(he)雜(za)質。若切面(mian)是(shi)(shi)結晶細密型(xing)的(de)(de)(de)(de)則(ze)是(shi)(shi)質量(liang)比(bi)較(jiao)優越(yue)的(de)(de)(de)(de)。我們(men)首先(xian)得考慮基板(ban)(ban)(ban)(ban)(ban)(ban)和(he)腹(fu)膜(mo)(mo)鍍層(ceng)(ceng)的(de)(de)(de)(de)厚度，比(bi)較(jiao)好的(de)(de)(de)(de)彩(cai)(cai)(cai)鋼(gang)(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(fu)膜(mo)(mo)或(huo)者涂層(ceng)(ceng)厚度往往只有(you)0.15mm以下(xia)。 觀(guan)(guan)察基板(ban)(ban)(ban)(ban)(ban)(ban)厚度和(he)覆(fu)膜(mo)(mo)的(de)(de)(de)(de)厚度，彩(cai)(cai)(cai)鋼(gang)(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)(cai)色的(de)(de)(de)(de)腹(fu)膜(mo)(mo)或(huo)者鍍層(ceng)(ceng)構成的(de)(de)(de)(de)。聽聲(sheng)音用(yong)手指或(huo)用(yong)硬物敲擊(ji)彩(cai)(cai)(cai)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)(ban)(ban)，彩(cai)(cai)(cai)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)(ban)(ban)的(de)(de)(de)(de)材質如(ru)果較(jiao)差，則(ze)發出來的(de)(de)(de)(de)聲(sheng)音是(shi)(shi)悶(men)的(de)(de)(de)(de)，金(jin)屬(shu)聲(sheng)音不明顯，材質較(jiao)好的(de)(de)(de)(de)彩(cai)(cai)(cai)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)(ban)(ban)金(jin)屬(shu)聲(sheng)音是(shi)(shi)比(bi)較(jiao)響亮、清脆的(de)(de)(de)(de)。觀(guan)(guan)察彩(cai)(cai)(cai)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)(ban)(ban)的(de)(de)(de)(de)外(wai)漏邊緣，拿(na)到一塊彩(cai)(cai)(cai)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)(ban)(ban)，因為從影響彩(cai)(cai)(cai)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)(ban)(ban)的(de)(de)(de)(de)使用(yong)時間來看，基板(ban)(ban)(ban)(ban)(ban)(ban)的(de)(de)(de)(de)厚度是(shi)(shi)很重要的(de)(de)(de)(de)。而(er)有(you)些生產彩(cai)(cai)(cai)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)(ban)(ban)的(de)(de)(de)(de)廠家往往在(zai)基板(ban)(ban)(ban)(ban)(ban)(ban)及彩(cai)(cai)(cai)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)(ban)(ban)涂層(ceng)(ceng)或(huo)覆(fu)膜(mo)(mo)上做手腳，他們(men)降低(di)基板(ban)(ban)(ban)(ban)(ban)(ban)的(de)(de)(de)(de)厚度，但是(shi)(shi)增加腹(fu)膜(mo)(mo)的(de)(de)(de)(de)厚度來降低(di)彩(cai)(cai)(cai)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)(ban)(ban)的(de)(de)(de)(de)生產成本(ben)，這(zhe)就大大降低(di)了彩(cai)(cai)(cai)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)(ban)(ban)的(de)(de)(de)(de)使用(yong)壽命了。
