As we all know, carton is produced by coating, bonding and forming after drying; while the color box paperboard is not heated and dried, and the moisture in the glue permeates into the paper, and the water on the color surface is blocked by the film of plastic (structure: synthetic resin, plasticizer, stabilizer and pigment), the moisture in the box blank is not good for a long time When it comes to emission, it naturally softens and reduces the intensity. Industrial paper tube is a tubular object made of paper. Most paper tubes are spiral paper tubes and seamless paper tubes. Therefore, we look for solutions from the following factors:

⒈紙張搭配（collocation)

1. Paper collocation

有些企業(yè)存在這樣一個誤區(qū)：里面紙用的克重愈大愈能增加紙箱(carton)的承壓力和抗壓強度（strength)，其實不然。欲增強彩箱彩盒的承壓力、抗壓強度必須增強芯紙的承壓能力，只要面紙裱膠后不顯瓦楞(wǎ léng)痕跡就應盡量采用克重紙張；芯紙、瓦紙好使用挺力好、環(huán)壓強度高的草漿或木漿紙。不要使用中強、或普強瓦紙，因其多為生漿和再生漿的混合物，吸水快、環(huán)壓強度、韌性雖好但挺度。經(jīng)試驗，采用可勃法測定（gage）中強瓦紙比劃漿紙吸水率高15%－30%左右；里紙可適當增加克重。實踐證明，降里面紙的克重，增加瓦紙、芯紙克重，無論是從質(zhì)量還是價位上更具競爭(competition)優(yōu)勢。

Some enterprises have such a misunderstanding: the larger the gram weight of the paper inside, the greater the pressure and strength of cartons can be increased. In fact, it is not. In order to enhance the pressure bearing capacity and compressive strength of color box, the pressure bearing capacity of core paper must be enhanced. As long as there is no corrugation (w ǎ L é ng) mark on the surface paper, the low gram weight paper should be used as far as possible; straw pulp or wood pulp paper with good stiffness and high ring crush strength should be used for core paper and tile paper. Do not use medium strength or ordinary strong tile paper, because it is mostly a mixture of raw pulp and recycled pulp, fast water absorption, low ring crush strength, good toughness but low stiffness. The results show that the water absorption rate of medium strength tile paper is 15% - 30% higher than that of the size paper, and the weight of inner paper can be increased appropriately. Practice has proved that reducing the gram weight of inner paper and increasing the gram weight of tile paper and core paper have more competitive advantages both in quality and price.

⒉膠的質(zhì)量(Mass)

2. Glue quality (mass)

紙箱生產(chǎn)現(xiàn)在使用的大都是自制或購買的玉米淀粉(starch)膠。連云港紙箱廠在確保紙箱產(chǎn)品質(zhì)量的前提下，可因地制宜地設置質(zhì)量檢驗機構(gòu)及配備質(zhì)量檢驗人員。的玉米膠不但粘合強度好，而且還能增強紙板(zhǐ bǎn)的承壓力、挺力等，且箱體不易變形。玉米淀粉膠的優(yōu)劣與制作工藝、環(huán)境、原輔料質(zhì)量(Mass)、攪拌時間等有密切的關(guān)系。玉米淀粉的質(zhì)量要求，細度98－100目，灰分不超過0.1%；含水量14.0%；酸度20CC/100g；二氧(Oxygen)化（oxidation)硫0.004%；氣味正常；顏色白或略帶微黃。

The production of cartons now mostly uses self-made or purchased corn starch glue. On the premise of ensuring the quality of carton products, Lianyungang carton factory can set up quality inspection organization and staff according to local conditions. High quality corn glue not only has good adhesion strength, but also can enhance the pressure and stiffness of paperboard (zh ǐ B ǎ n), and the box is not easy to deform. The advantages and disadvantages of corn starch adhesive are closely related to the production process, environment, quality of raw and auxiliary materials (mass), mixing time, etc. The quality requirements of corn starch are as follows: fineness 98-100 mesh, ash content no more than 0.1%; water content 14.0%; acidity 20cc / 100g; oxygen sulfur 0.004%; normal smell; white or slightly yellow color.

制膠淀粉質(zhì)量如不此標準，可視情況適當降水比。氣溫升高，水比應相應減少，硼（B)砂，片堿(Alkali)應酌情增加，雙氧(Oxygen)水應減少用量。熟膠制好后不宜久放，尤其夏季好隨做隨用，膠液里加入甲醛3%－4%、甘油、硼酸各0.1%，可增加紙張阻水能力、加快粘合速度、增強紙板(zhǐ bǎn)硬度。

If the quality of gelatinized starch does not meet the standard, the water ratio can be reduced appropriately according to the situation. With the increase of air temperature, the water ratio should be reduced accordingly, the amount of boron (b) sand and flake alkali should be increased as appropriate, and the amount of oxygen water should be reduced. The prepared glue should not be kept for a long time, especially in summer. Formaldehyde 3% - 4%, glycerol and boric acid 0.1% are added to the glue solution, which can increase the water resistance of paper, speed up the bonding speed and enhance the hardness of paperboard.

除此外，在裱貼紙板時亦可采用環(huán)保(Environmental protection)型化學膠，即PVA粘合劑。其特點是裱貼瓦楞紙板平整、挺直、粘合好，經(jīng)久不變形，其制作方法是（以100kg粘合劑為例）：用料配比：聚乙烯醇13.7kg，醋酸聚乙烯醇乳液2.74kg，草酸1.37kg，水82kg，水比1∶6）。，將水加熱90℃，加入聚乙燃醇攪拌均勻（jūn yún)，繼續(xù)加熱水沸，保溫3小時，再加入草酸攪拌，后加入醋酸聚乙烯醇乳液攪拌均勻即成。

In addition, environmental protection type chemical adhesive, namely PVA adhesive, can be used for mounting paperboard. It is characterized by flat, straight and adhesive bonding of corrugated paperboard. It can not be deformed for a long time. Its manufacturing method is (taking 100kg adhesive as an example): material ratio: polyvinyl alcohol 13.7kg, polyvinyl acetate emulsion 2.74kg, oxalic acid 1.37kg, water 82kg, water ratio 1: 6). First of all, heat the water to 90 degrees, add polyethyl alcohol to stir evenly (J N Y N), continue heating to boiling water, heat for 3 hours, then add oxalic acid to stir, and finally add polyvinyl acetate emulsion to stir evenly.

⒊涂膠量

3. Gluing amount

無論是手工還是自動機械裱貼彩面，涂膠量不宜過大。連云港紙箱廠在確保紙箱產(chǎn)品質(zhì)量的前提下，可因地制宜地設置質(zhì)量檢驗機構(gòu)及配備質(zhì)量檢驗人員。實際生產(chǎn)中，有些員工為了避免脫膠人為增加涂膠量，這是不足取的，必須嚴格控制。涂膠量應以80－110g/m2為佳。不過要視瓦楞大小調(diào)節(jié)(adjust)，掌握住膠量均勻涂布楞峰為宜，只要不脫膠，膠量越少越好。

Whether it is manual or automatic mechanical mounting color surface, the amount of glue should not be too large. On the premise of ensuring the quality of carton products, Lianyungang carton factory can set up quality inspection organization and staff according to local conditions. In actual production, in order to avoid degumming, some employees increase the amount of glue, which is insufficient and must be strictly controlled. 80-110g / m2 is the best. However, depending on the size of the corrugation (adjust), the amount of glue evenly coated ridge peak is appropriate, as long as not degumming, the less glue the better.

⒋單面紙板的質(zhì)量

4. Quality of single side paperboard

單面瓦楞(wǎ léng)紙板(zhǐ bǎn)的質(zhì)量(Mass)是由原紙的質(zhì)量、瓦楞楞型、瓦楞機的工作(job)溫度、粘合劑質(zhì)量、機器運行速度，操作者技術(shù)水平?jīng)Q定的。

The mass of single side corrugated paperboard is determined by the quality of base paper, corrugating type, working temperature of corrugating machine, quality of adhesive, running speed of machine and technical level of operator.
