As we all know, there are many factors that affect the quality of the product, summed up are mainly: people, machines, materials, law, ring five major factors. Then, the five major factors that affect the speed of corrugated board production are also mainly.
First, the so-called machine is our production tool, it is a machine.
The inherent deficiency of the machine is one of the important aspects that affect the production speed. Due to the lack of understanding of the equipment when purchasing the equipment, or the emphasis on low prices, the company purchased equipment that is not mature or defective.
such as:
1. The thermal efficiency of the corrugating machine is low or simply cannot meet the temperature required for production from 160°C to 180°C.
2. The diameter of the corrugating roller is small, but the manufacturer marks the high speed.
3. The preheating cylinder bore is very small, and some of them do not even have a wrap angle adjustment device, so it is impossible to fully preheat the base paper.
4, the heating section of the dryer is very short, the lack of drying after the double-sided machine is glueed, bad glue paste.
5, the cooling section is very short, it has an effect on the cardboard moisture distribution, stereotypes, and sticky.
Second, the so-called material is the raw material that we need for production, mainly raw paper and adhesives .
Some manufacturers are pursuing low-cost, low-cost, low-quality base papers that have poor pulling force and excessive moisture, and use these base papers for production.
For adhesives, although it accounts for less than 1% of the total cost, it can affect the manufacturer's large profits. At the same time, the quality of the adhesive is one of the reasons that directly affects the production speed.
Because the adhesives are produced by the manufacturers themselves, they are also very easy to control. There are mainly the following aspects:
1, the viscosity, the so-called viscosity is the internal friction of the fluid, is the resistance of a layer of liquid and another layer of liquid relative movement. Viscosity changes with temperature, stirring force, and storage time. As for the board machine, the main factor affecting the amount of paste under the same paste gap is the viscosity. High or low viscosity will affect the production speed.
2, the concentration, the so-called concentration is the solid content of the binder, that is to say the ratio of the weight of the residue after heating the binder at a certain temperature and the weight of the sample, expressed as a percentage.
Under normal circumstances, the production of low viscosity, high concentration of adhesive is a good way to improve the machine speed.
3. Gelatinization temperature, The so-called gelatinization temperature is the initial temperature at which the paste is formed, and it varies with the type of starch, modification of the starch, and additives in the whey. The gelatinization temperature of the binder also directly affects the production speed. Of course, the gelatinization temperature can also be adjusted, and the gelatinization temperature can be adjusted by adjusting the amount of caustic soda to change the production speed and increase the production efficiency.
Third, the so-called method is the production method, refers to the production of corrugated cardboard process specification. Of course, the production process specifications for different types of machinery and equipment are also not the same. Only by strictly following the corresponding process specifications can production be achieved.
Fourth, the so-called ring refers to the environment. Here, although the environment is not a direct cause, it should also be noted. This is not repeated here.
5. People are the most critical factor and the most unstable factor. Of course, they are the most difficult factors to control.
The qualified technicians are seriously deficient. Operators in various key processes are not skilled enough in the equipment's ability to control the equipment. The necessary training and learning of the employees have not caused the company's high attention. Sometimes, even if the technicians in each key process are in good condition, the lack of good teamwork and the spirit of mutual cooperation are also the key to the speed of production. At the same time, it will cause great unnecessary waste for the company.
In short, the equipment is operated by humans. The base paper is inspected by humans. The adhesive is made by humans. The procedure is required to be followed by people. After all, only the overall level of the operators has improved the awareness of the regiment. The production speed of corrugated cardboard is very fast. It is easy to improve, so that it is not difficult to produce high-quality products.

Hair removal wax uses the viscosity of the wax to stick to the body hair and uproot the hair shaft from the hair follicle. However, because the dermal papilla is not damaged, the hair will regenerate, but the rate of regeneration is relatively slow.Hot wax is a mixture of beeswax and resin. Generally in a solid state, before use need to be heated to dissolve, until the temperature is reduced to suitable skin, can be painted on the skin.
Method of Use
1. Smooth the hair with the palm of your hand in the direction it grows.
2. Apply a little wax directly to the skin with a glue stick. Do not take too much wax each time. If necessary, separate several times.
3. Tighten the skin and pull it up quickly against the hair. Then the hair can be removed with roots.
