長春彩鋼卷專賣

    觀察基板厚度和覆膜的厚度，彩鋼板是(shi)有基(ji)板(ban)(ban)(ban)(ban)(ban)和(he)彩(cai)(cai)(cai)色(se)的(de)(de)(de)腹(fu)(fu)膜或者鍍層(ceng)(ceng)構成(cheng)的(de)(de)(de)。我們首先(xian)得考慮基(ji)板(ban)(ban)(ban)(ban)(ban)和(he)腹(fu)(fu)膜鍍層(ceng)(ceng)的(de)(de)(de)厚度(du)，比較好的(de)(de)(de)彩(cai)(cai)(cai)鋼(gang)板(ban)(ban)(ban)(ban)(ban)基(ji)板(ban)(ban)(ban)(ban)(ban)是(shi)0.02~0.05mm，覆膜或者涂層(ceng)(ceng)厚度(du)往(wang)往(wang)只有0.15mm以下(xia)。因(yin)為從影響彩(cai)(cai)(cai)鋼(gang)板(ban)(ban)(ban)(ban)(ban)的(de)(de)(de)使(shi)用(yong)(yong)時間(jian)來看，基(ji)板(ban)(ban)(ban)(ban)(ban)的(de)(de)(de)厚度(du)是(shi)很重(zhong)要的(de)(de)(de)。而有些(xie)生(sheng)產彩(cai)(cai)(cai)鋼(gang)板(ban)(ban)(ban)(ban)(ban)的(de)(de)(de)廠家往(wang)往(wang)在基(ji)板(ban)(ban)(ban)(ban)(ban)及(ji)彩(cai)(cai)(cai)鋼(gang)板(ban)(ban)(ban)(ban)(ban)涂層(ceng)(ceng)或覆膜上做(zuo)手腳，他們降低基(ji)板(ban)(ban)(ban)(ban)(ban)的(de)(de)(de)厚度(du)，但是(shi)增加腹(fu)(fu)膜的(de)(de)(de)厚度(du)來降低彩(cai)(cai)(cai)鋼(gang)板(ban)(ban)(ban)(ban)(ban)的(de)(de)(de)生(sheng)產成(cheng)本，這就大大降低了(le)彩(cai)(cai)(cai)鋼(gang)板(ban)(ban)(ban)(ban)(ban)的(de)(de)(de)使(shi)用(yong)(yong)壽命了(le)。

    聽聲音(yin)(yin)用(yong)手指或(huo)用(yong)硬物(wu)敲擊彩鋼(gang)板，彩鋼(gang)板的材質如果(guo)較(jiao)差，則發(fa)出(chu)來的聲音(yin)(yin)是悶的，金屬聲音(yin)(yin)不明顯，材質較(jiao)好的彩鋼(gang)板金屬聲音(yin)(yin)是比(bi)較(jiao)響亮、清脆(cui)的。觀察(cha)彩鋼(gang)板的外漏邊緣，拿(na)到一塊彩鋼(gang)板，我(wo)先觀察(cha)彩鋼(gang)板外露鋼(gang)材如斷面(mian)等(deng)是否結(jie)晶細(xi)密(mi)(mi)，是否發(fa)灰、發(fa)暗和雜(za)質。若切面(mian)是結(jie)晶細(xi)密(mi)(mi)型(xing)的則是質量比(bi)較(jiao)優(you)越(yue)的。
