1、紙型配搭
1. Paper matching
一些企業(yè)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(huán)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(zhì),吸濕快、環(huán)壓抗拉強度、可塑性雖好但挺度。經(jīng)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(jīng)驗,降里面紙的凈重,提高瓦紙、芯紙凈重,無論是從質(zhì)量還是價錢上具備核心競爭力。
Some enterprises have such a wrong point of view: the larger the net weight of paper used in the paper box, the more it can improve the pressure bearing force and tensile strength of the paper box. In order to improve the pressure-bearing and tensile strength of color box packaging, it is necessary to improve the bearing capacity of core paper. If the scratch of corrugated paperboard can not be seen after laminating, low net weight paper should be used as far as possible; straw pulp or wood pulp paper with good stiffness and high tensile strength of ring compression should be used for core paper and tile paper. There is no need to use medium strength or ordinary strong tile paper, because it has more chemical substances for making pulp and remodeling pulp. It has fast moisture absorption, low tensile strength under ring compression, good plasticity but low stiffness. The test shows that the water content of the medium strength tile paper is 16% - 40% higher than that of the bottom paper, and the net weight of the inner paper can be appropriately increased. Practical experience, reduce the net weight of inner paper, improve the net weight of tile paper and core paper, and have core competitiveness in terms of quality and price.

2、膠的質(zhì)量
2. Quality of glue
??紙箱生產(chǎn)現(xiàn)如今運用的大部分是自做或購買的玉米淀粉膠。高品質(zhì)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(yōu)劣與制作工藝、自然環(huán)境、原料采購質(zhì)量、攪拌時間等有密不可分的關(guān)系。玉米淀粉的質(zhì)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(diào)白或有點淡黃。
Nowadays, most of the cartons are self-made or purchased corn starch glue. High quality corn glue not only has good tensile strength, but also can improve the pressure and stiffness of cardboard, and the cover is not easy to deform. The advantages and disadvantages of corn starch adhesive are closely related to the production technology, natural environment, raw material purchasing quality, mixing time, etc. The quality requirements of corn starch are as follows: particle size 97-150 mesh, ash content no more than 0.5%, moisture content 14.0%, acid value 30cc / 150g, nitrogen dioxide 0.004%, taste sure, white or a little light yellow.
制膠淀粉質(zhì)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(nèi)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 water ratio should be appropriately reduced. With climate warming, the water ratio should be reduced, borax and flake alkali should be increased, and the demand of hydrogen peroxide should be reduced. The prepared glue should not be put for a long time, especially when it is filled in summer. When indoor formaldehyde 3% - 4%, glycerol and boric acid are added to the adhesive, the water retaining capacity of paper shape can be improved, the bonding speed can be accelerated, and the compressive strength of cardboard can be improved.

3、點膠量
3. Dispensing quantity
無論是手工制做還是自動式工業(yè)設備裱貼彩面,點膠量不宜過大。事實上生產(chǎn)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(guī)格調(diào)節(jié),掌握住合模力均勻調(diào)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, the amount of glue should not be too large. In fact, in production and processing, some employees in order to prevent the opening of human factors to increase the amount of dispensing, which is insufficient, must be strictly controlled. The optimum dispensing amount should be 90-120g / M1. Only according to the corrugated board specification adjustment, grasp the clamping force evenly adjust the ridge peak is appropriate, if do not open the glue, the lower the clamping force, the higher.
4、單雙面硬紙板的質(zhì)量
4. Quality of single and double sided cardboard
單雙面紙箱的質(zhì)量是由箱板紙的質(zhì)量、瓦楞楞型、瓦楞機的工作溫度、粘合劑質(zhì)量、開停機速度,施工人員技術(shù)水平?jīng)Q策的。
The quality of single and double sided cartons is decided by the quality of board paper, corrugated type, working temperature of corrugating machine, adhesive quality, starting and stopping speed, and technical level of construction personnel.
