長春彩鋼卷哪家好

    我先觀察彩鋼板外露鋼(gang)材如斷面(mian)等是(shi)(shi)(shi)否結(jie)晶細(xi)密(mi)，是(shi)(shi)(shi)否發灰(hui)、發暗和雜質。若切面(mian)是(shi)(shi)(shi)結(jie)晶細(xi)密(mi)型(xing)的(de)(de)(de)(de)(de)則是(shi)(shi)(shi)質量(liang)比(bi)較(jiao)(jiao)優越的(de)(de)(de)(de)(de)。我們(men)首先得考慮(lv)基(ji)板(ban)(ban)(ban)(ban)(ban)和腹(fu)膜(mo)(mo)(mo)鍍(du)層(ceng)(ceng)的(de)(de)(de)(de)(de)厚(hou)度(du)(du)，比(bi)較(jiao)(jiao)好的(de)(de)(de)(de)(de)彩(cai)(cai)(cai)(cai)鋼(gang)板(ban)(ban)(ban)(ban)(ban)基(ji)板(ban)(ban)(ban)(ban)(ban)是(shi)(shi)(shi)0.02~0.05mm，覆膜(mo)(mo)(mo)或者涂(tu)層(ceng)(ceng)厚(hou)度(du)(du)往(wang)往(wang)只(zhi)有(you)0.15mm以下(xia)。 觀察基(ji)板(ban)(ban)(ban)(ban)(ban)厚(hou)度(du)(du)和覆膜(mo)(mo)(mo)的(de)(de)(de)(de)(de)厚(hou)度(du)(du)，彩(cai)(cai)(cai)(cai)鋼(gang)板(ban)(ban)(ban)(ban)(ban)是(shi)(shi)(shi)有(you)基(ji)板(ban)(ban)(ban)(ban)(ban)和彩(cai)(cai)(cai)(cai)色(se)的(de)(de)(de)(de)(de)腹(fu)膜(mo)(mo)(mo)或者鍍(du)層(ceng)(ceng)構(gou)成的(de)(de)(de)(de)(de)。聽聲(sheng)(sheng)音(yin)用手(shou)指或用硬物敲(qiao)擊彩(cai)(cai)(cai)(cai)鋼(gang)板(ban)(ban)(ban)(ban)(ban)，彩(cai)(cai)(cai)(cai)鋼(gang)板(ban)(ban)(ban)(ban)(ban)的(de)(de)(de)(de)(de)材質如果較(jiao)(jiao)差(cha)，則發出來的(de)(de)(de)(de)(de)聲(sheng)(sheng)音(yin)是(shi)(shi)(shi)悶(men)的(de)(de)(de)(de)(de)，金屬聲(sheng)(sheng)音(yin)不(bu)明顯，材質較(jiao)(jiao)好的(de)(de)(de)(de)(de)彩(cai)(cai)(cai)(cai)鋼(gang)板(ban)(ban)(ban)(ban)(ban)金屬聲(sheng)(sheng)音(yin)是(shi)(shi)(shi)比(bi)較(jiao)(jiao)響亮、清脆(cui)的(de)(de)(de)(de)(de)。觀察彩(cai)(cai)(cai)(cai)鋼(gang)板(ban)(ban)(ban)(ban)(ban)的(de)(de)(de)(de)(de)外漏邊緣，拿(na)到一塊彩(cai)(cai)(cai)(cai)鋼(gang)板(ban)(ban)(ban)(ban)(ban)，因為從影響彩(cai)(cai)(cai)(cai)鋼(gang)板(ban)(ban)(ban)(ban)(ban)的(de)(de)(de)(de)(de)使(shi)用時間(jian)來看，基(ji)板(ban)(ban)(ban)(ban)(ban)的(de)(de)(de)(de)(de)厚(hou)度(du)(du)是(shi)(shi)(shi)很重(zhong)要的(de)(de)(de)(de)(de)。而有(you)些生(sheng)產彩(cai)(cai)(cai)(cai)鋼(gang)板(ban)(ban)(ban)(ban)(ban)的(de)(de)(de)(de)(de)廠家往(wang)往(wang)在基(ji)板(ban)(ban)(ban)(ban)(ban)及彩(cai)(cai)(cai)(cai)鋼(gang)板(ban)(ban)(ban)(ban)(ban)涂(tu)層(ceng)(ceng)或覆膜(mo)(mo)(mo)上做(zuo)手(shou)腳，他們(men)降低(di)基(ji)板(ban)(ban)(ban)(ban)(ban)的(de)(de)(de)(de)(de)厚(hou)度(du)(du)，但是(shi)(shi)(shi)增加腹(fu)膜(mo)(mo)(mo)的(de)(de)(de)(de)(de)厚(hou)度(du)(du)來降低(di)彩(cai)(cai)(cai)(cai)鋼(gang)板(ban)(ban)(ban)(ban)(ban)的(de)(de)(de)(de)(de)生(sheng)產成本，這就大大降低(di)了(le)彩(cai)(cai)(cai)(cai)鋼(gang)板(ban)(ban)(ban)(ban)(ban)的(de)(de)(de)(de)(de)使(shi)用壽(shou)命了(le)。
