    瓦楞紙箱平整度如何控制大家知道嗎?

    來源:http://www.zywygg.com 發(fā)布時間:2019-12-10

      瓦楞紙箱廠家要保證紙箱的質(zhì)量,對于生產(chǎn)紙板的平整度一定要控制好,因為這對紙箱的整體效果和承載能力有很大的影響。那么影響瓦楞紙箱平整度的因素是什么呢?
      Corrugated box manufacturers should ensure the quality of the box, and the flatness of the production board must be well controlled, because it has a great impact on the overall effect and bearing capacity of the box. So what are the factors that affect the flatness of corrugated boxes?
      有一些要求瓦楞紙箱的生產(chǎn)材料和機械設(shè)備,因為生產(chǎn)的瓦楞紙箱紙定量差異,和紙張水分含量是不同的,本文通過加熱器的角,受熱面長度選擇和調(diào)節(jié)不當(dāng)或角,受熱面長度不能任意調(diào)節(jié)。前者由于操作不當(dāng),后者由于設(shè)備的限制,影響了預(yù)熱干燥效果,導(dǎo)致紙箱平整度出現(xiàn)問題。還有就是不能正確應(yīng)用蒸汽噴涂安裝或設(shè)備沒有噴涂安裝,所以不能隨意增加紙張濕度。紙張預(yù)熱后分布水分時間不足或環(huán)境濕度大,通風(fēng)不良,消耗線速度不當(dāng)。單一瓦楞紙機、上膠機數(shù)量不適當(dāng)、不均勻和不均勻膨脹紙板的介紹。蒸汽壓力不足或不穩(wěn)定,疏水閥等附件損壞,或管道排水不暢,導(dǎo)致預(yù)熱器不能正常波動。

      There are some requirements for corrugated box production materials and mechanical equipment, because the quantitative difference of corrugated box paper produced is different from the moisture content of paper. In this paper, through the angle of heater, the length of heating surface is not selected and adjusted properly or the angle, the length of heating surface cannot be adjusted arbitrarily. Due to the improper operation of the former and the limitation of the latter, the preheating and drying effect is affected, which leads to the problem of the evenness of the cartons. There is also the incorrect application of steam spray installation or equipment is not spray installation, so can not increase the paper humidity at will. After paper preheating, the distribution time of moisture is insufficient or the environmental humidity is large, the ventilation is poor, and the consumption line speed is improper. The introduction of a single corrugating machine, glue machine with inappropriate number, uneven and uneven expansion board. The steam pressure is insufficient or unstable, the accessories such as drain valve are damaged, or the pipeline drainage is not smooth, which causes the preheater not to fluctuate normally.
      平整度也是能否生產(chǎn)出好的瓦楞紙箱的標(biāo)準(zhǔn),在生產(chǎn)瓦楞紙箱時必須嚴(yán)格要求工作步驟。以上是瓦楞紙箱廠家為大家介紹的相關(guān)內(nèi)容,想要了解更多內(nèi)容,歡迎訪問網(wǎng)站:http://www.zywygg.comFlatness is also the standard of producing good corrugated box. The working steps must be strictly required in the production of corrugated box. The above is the relevant content introduced by the corrugated box manufacturer for you.
