紙箱廠家是如何解決紙箱的抗拉強度的?

來源:http://www.xmntn.com 時間:2020-05-28

1、紙型配搭
1. Paper matching
一些企業存在這樣1個錯誤觀點:里面紙用的凈重愈大愈能提高紙箱子的承壓力和抗拉強度,各抒已見。欲提升彩箱彩盒包裝的承壓力、抗拉強度必需提升芯紙的承受力工作能力,如果面紙裱膠后看不出來瓦楞紙板劃痕就應盡量采用凈重紙型;芯紙、瓦紙好運用挺力好、環壓抗拉強度高的草漿或木漿紙。無須運用中強、或普強瓦紙,因其多謀生漿和重塑漿的化學物質,吸濕快、環壓抗拉強度、可塑性雖好但挺度。經試驗,采用可勃測定法中強瓦紙筆畫漿紙含水量高16%-40%上下;里紙可適當提高凈重。實踐經驗,降里面紙的凈重,提高瓦紙、芯紙凈重,無論是從質量還是價錢上具備核心競爭力。
Some enterprises have such 1 wrong view: the greater the net weight of the inside paper is, the higher the pressure and tensile strength of the paper box will be. In order to improve the pressure bearing and tensile strength of color box packaging, it is necessary to improve the working capacity of the core paper. If the surface paper can not see the scratches on the corrugated board after mounting, the paper type of low net weight should be used as far as possible; the straw or wood pulp paper with good stiffness and high tensile strength of ring pressure should be used for the core paper and tile paper. It is not necessary to use medium strength or common strength tile paper. Because of the chemical substances in the pulp for making a living and remodeling, it has the advantages of fast moisture absorption, low ring pressure tensile strength, good plasticity but low stiffness. The results show that the water content of medium strength tile paper is 16% - 40% higher than that of medium strength tile paper, and the net weight of inner paper can be increased properly. Practical experience, reduce the net weight of inner paper, improve the net weight of tile paper and core paper, and have core competitiveness in quality and price.

2、膠的質量
2. Glue quality
紙箱生產現如今運用的大部分是自做或購買的玉米淀粉膠。高品質的苞米膠不但粘合抗拉強度好,而且還能提升硬紙板的承壓力、挺力等,且罩殼不易變形。玉米淀粉膠的優劣與制作工藝、自然環境、原料采購質量、攪拌時間等有密不可分的關系。玉米淀粉的質量要求,粒度97-150目,灰分不超過0.5%;水分含量14.0%;酸值30Cc/150g;二氧化氮0.004%;味道確定沒問題;色調白或有點淡黃。
Now most of the cartons are made or purchased corn starch glue. High quality rice glue not only has good adhesive tensile strength, but also can improve the bearing pressure and taping force of cardboard, and the shell is not easy to deform. The advantages and disadvantages of corn starch gum are closely related to the production process, natural environment, raw material procurement quality, mixing time, etc. The quality requirements of corn starch are as follows: grain size is 97-150 mesh, ash content is not more than 0.5%; moisture content is 14.0%; acid value is 30cc / 150g; nitrogen dioxide is 0.004%; taste is OK; color is white or a little yellowish.
制膠淀粉質量如不此標準,精確性情況適當降水比。氣候變暖,水比應相對性減少,硼砂,片堿應酌定提高,雙氧水應減少需求量。熟膠制好后不宜久放,尤其夏季隨做隨充,黏劑里加上室內甲醛3%-4%、甘油、硼酸各0.5%,可提高紙型擋水工作能力、加快粘合速度、提升硬紙板抗壓強度。
If the quality of gelatinized starch does not meet this standard, the accuracy should be reduced properly. With climate warming, the water ratio should be reduced, borax and sodium hydroxide should be increased, and hydrogen peroxide should be reduced. It should not be put for a long time after the clinker is made, especially when it is filled in summer. The adhesive, with 3% - 4% formaldehyde, 0.5% glycerin and 0.5% boric acid in the room, can improve the water retaining capacity of paper, accelerate the bonding speed and enhance the compressive strength of cardboard.

3、點膠量
3. Dispensing amount
無論是手工制做還是自動式工業設備裱貼彩面,點膠量不宜過大。事實上生產加工中,一些員工為了防止開膠人為因素提高點膠量,這是不足取的,必需嚴格控制。點膠量應以90-120g/m1為宜。只有要視瓦楞紙板規格調節,掌握住合模力均勻調膠楞峰為宜,如果不開膠,合模力越越高。
Whether it is hand-made or automatic industrial equipment mounting color surface, dispensing amount should not be too large. In fact, in the production and processing, some employees in order to prevent artificial factors to improve the dispensing amount, which is insufficient, must be strictly controlled. The dispensing amount should be 90-120g / M1. Only depending on the specification of corrugated board, it is better to control the closing force and adjust the peak of the glue evenly. If the glue is not opened, the lower the closing force is, the higher it is.
4、單雙面硬紙板的質量
4. Quality of single and double sided cardboard
單雙面紙箱的質量是由箱板紙的質量、瓦楞楞型、瓦楞機的工作溫度、粘合劑質量、開停機速度,施工人員技術水平決策的。
The quality of single and double sided cartons is determined by the quality of box board paper, corrugating type, operating temperature of corrugating machine, quality of adhesive, starting and stopping speed, and technical level of construction personnel.
