瓦楞紙箱的強度在生產(chǎn)上有什么要求?

來源:http://www.cdhpd.com 發(fā)布時間:2020-01-13

  經(jīng)常看到紙箱在我們生活中,很多事情,和日常必需品,電器是用紙盒包裝,以保護他們,在使用的過程中,容易處理,可以回收使用綠色的要求,但各種各樣的紙箱也多種多樣,瓦楞紙箱屬于其中之一,是一種使用較廣泛的包裝產(chǎn)品,起到美化商品,宣傳商品的作用,裝卸運輸。
  It is often seen that cartons are used in our daily life for many things and daily necessities. Electrical appliances are packed in cartons to protect them. In the process of use, they are easy to handle and can be recycled to meet the requirements of environmental protection. However, there are many kinds of cartons. Corrugated cartons belong to one of them. They are widely used packaging products, which play the role of beautifying commodities, publicizing commodities, loading, unloading and transportation 。

  人們對瓦楞紙箱的功能要求越來越高。瓦楞紙箱具有多種功能,合理的紙箱形狀和尺寸設(shè)計是非常重要的。瓦楞紙板自動生產(chǎn)線、印刷工藝、后處理及成型工藝;印刷工作基本實現(xiàn)了印刷、開槽、模切、粘盒、包裝的一次成型自動化。瓦楞紙板強度要求1.1:邊壓強度:沿瓦楞紙板方向,單位長度瓦楞紙板前壓送能承受的較大力。單位:N / m。
  People have higher and higher requirements for the functions of corrugated boxes. Corrugated box has many functions. It is very important to design the reasonable shape and size of the box. Corrugated board automatic production line, printing process, post-processing and forming process; printing basically realizes the one-time forming automation of printing, slotting, die-cutting, gluing and packaging. Corrugated board strength requirements 1.1: edge pressure strength: along the direction of corrugated board, the unit length of corrugated board can bear more pressure before feeding. Unit: n / m.
  邊緣抗壓強度=表面紙復(fù)合環(huán)抗壓強度+復(fù)合瓦楞紙復(fù)合環(huán)抗壓強度*收縮率(可靠),實際試驗值宜大于理論計算值。1.2:破斷強度:瓦楞紙板在開裂前單位面積所能承受的較大外力均勻增大。單位:公斤/平方厘米。紙板的斷裂強度=面紙的斷裂強度+紙介質(zhì)情況下的斷裂強度+底紙的斷裂強度*由于制造過程中的某些強度損失,實際測試的斷裂強度的計算值要小于1公斤/平方厘米。1.3:天津瓦楞紙箱沖壓強度:新國標(biāo)gb6544-1999了對紙板沖壓強度的要求。
  Edge compressive strength = surface paper composite ring compressive strength + composite corrugated paper composite ring compressive strength * shrinkage rate (safe and reliable), the actual test value should be greater than the theoretical calculation value. 1.2: breaking strength: the larger external force that the corrugated board can bear per unit area before cracking increases uniformly. Unit: kg / cm2. The breaking strength of the paperboard = breaking strength of the face paper + breaking strength of the paper medium + breaking strength of the base paper * due to some strength loss in the manufacturing process, the calculated breaking strength of the actual test should be less than 1 kg / cm2. 1.3: stamping strength of Tianjin corrugated box: the new national standard GB 6544-1999 has eliminated the requirement for the stamping strength of cardboard.
