求公式,纸业问题: 1.一吨纸等于几令? 2. 一令纸有多重?
推荐回答(1个)
首先,我们要明白通常说的80克 或者100G的纸是怎么一个概念,80克的纸,就是说一平方米的纸的重量有80克,80g/每平米。同理,90克108克157克都一样的。 再来说说令的单位,一令纸等于500张全开的纸(全开纸就是没有切过的纸)。计算一张纸的重量公式应该是这样的:长 X 宽 X 克重/每平米例如,大度157克的铜版纸一张多重?答:1194mm X 889mm X 157g/M2=0.166Kg那么一令纸就等于500 X 单张纸重量。这样一吨纸等于多少令就好算了:将1Kg 除以 1令纸的重量就知道结果了。常规大度纸(1194 X 889)系数(就是长X宽啦)=1。06常规正度纸(1092 X 787)系数=0。86所以计算的时候只需用系数乘以纸张克重就可以得到单张的重量了纸张换算公式 1.纸的单位: A.克:一平方米的重量(长×宽÷2)=g为重量 B.令:500张纸单位称:令(出厂规格) C.吨:与平常单位一样1吨=1000公斤,用于算纸价。 2.纸的规格及名称: A.纸最常见有四种规格: (1).正度纸:长109.2厘米.宽78.7厘米 (2).大度纸:长119.4厘米.宽88.9厘米 (3).不干胶:长765厘米.宽535厘米 (4).无碳纸:有正度和大度的规格,但有上纸.中纸.下纸之分,纸价不同一英寸 =2.54cm一线 =0.126克一公斤=2.2046磅一磅 =0.45公斤一码 =0.9144米正度:78.7cm×109.2cm(31”×43”英寸)大度:88.9cm×119.4cm(35”×47”英寸)一令 =500张(PCS)张价 =长度(m)×宽度(m)×克重(kg)×吨价(元/kg)如:0.787×1.092×0.175×4.5=0.676令价 =长度(m)×宽度(m)×克重(kg)×吨价(元/kg)×张数(500)吨价 =张价÷克重÷长度÷宽度重量 =长度×宽度×克重×数量张数 =总金额÷张价卷筒切张数 =卷筒重量÷克重÷长度÷宽度卷筒长度 =卷筒重量÷宽度÷克重
