Know how much! Do you know that a pack of flammable uses three kinds of corrugated paper?

In order to effectively guide the pulp and paper enterprises to apply for pollutant discharge permit, and to carry out pollution prevention and control from the technical and management service enterprises, the Guangxi Environmental Protection Research Institute and other departments have in-depth investigation of the production and operation of the pulp and paper enterprises in the jurisdiction, and compiled Guangxi Pulp and Paper Industry Pollution Prevention and Environmental Management Technical Manual, "Guangxi Pulp and Paper Industry Pollution Discharge Permit and Standardized Management Technical Guide" and "Guangxi Pulp and Paper Industry Special Treatment Plan" and other documents. For small texts and patterns, if it is to be expressed by overprinting, it is difficult to guarantee the accuracy of overprinting, which will inevitably lead to an increase in the rejection rate or the unattractiveness of the printed pattern, which is generally solved by trapping. For the grassroots staff, paper companies, schools, the public and other different groups, the POPs science knowledge, conventions, project conditions and advanced technologies, the eco-environment department carried out extensive publicity and training activities on different occasions. The public and the professionals were involved in the supervision of the work of reducing emissions and received good social effects. Cause white water and clean water waste When the liquid level of the slurry tank drops, it is necessary to increase the amount of supplementary water (usually clear water). When the liquid level of the slurry tank is too high, the excess overflow of white water passes through the net white pool, multiple discs, and clear filtrate. Pool, clean water tower, and finally overflow into the trench. At the same time, the ecological environment department of the autonomous region has also issued relevant policies, established a long-term mechanism, and improved the environmental supervision, testing and law enforcement capabilities of the management department. The slag remover concentration and the recoil effect are poor. The rinsing tank often provides the concentrated water and backflushing of the slag remover. For example, if the booster pump is equipped, the liquid level fluctuation will affect the slag removal. The concentration of the device (when the slag separation effect is deteriorated at ≥1%) and the recoil effect (the backlash is caused by the tail slag blocking or the fiber recovery efficiency is lowered). Mechanical properties of composite membranes The tensile strength of PLA composite membranes is affected by the addition of acetylated lignin to cresol. As shown in Fig. 4, the tensile strength of the composite membrane decreases first and then rises with the addition of acetyl acetate. In the gentle trend, the addition of acetic anhydride modified products showed a downward trend. The control of the paste amount can be set as an automatic gluing system, which can ensure the automatic control of the gluing amount, and secondly improve the hot plate ballast mode to prevent the cardboard from being crushed, resulting in uneven surface of the cardboard. The actual water consumption is lower than that of the sprinkler pipe before the transformation.

When the air content of the water system rises, the level of the slurry tank will fluctuate up and down, which will cause the flushing tank to have no overflow and sometimes a large overflow. This unstable overflow fluctuation is particularly easy to carry a large amount of air into the slurry water system and improve The air content of the slurry brings a series of chain reactions such as running failure, retention efficiency and dehydration efficiency, paper bubbles or perforations, reduced speed of production, reduced production efficiency, increased defoaming agent dosage (even affecting the sizing effect, increasing chemical cost). . For English words, especially small ones, it is necessary to consciously bold the strokes to avoid thinning or even dying of the strokes due to ink spreading during printing. On March 5, the former Yunnan Hongta Group Co., Ltd. and the founder of Yuxi Hongta Tobacco (Group) Co., Ltd., the founder of Yan Orange, died at the age of 91. * White water without air entrainment is above 95. The aluminum foil inside the cigarette case has two main functions: the fragrance. Some people may have heard the false statements about "smoked tobacco with paper". In fact, they only misunderstood the reconstituted tobacco leaves as "paper." In this study, acetylated lignin phenol was used to reduce the hydroxyl content of lignin phenol and increase the acyl content, so as to improve the mechanical properties of the composite membrane by improving the compatibility between lignin phenol and polylactic acid. The surface of the cardboard is not flat, and it is generally necessary to see whether the amount of paste and the paper strength are reasonable. By increasing the number of meshes first in the corrugated board production line, the mesh of the paste machine of the general paste machine is higher than that of the single-watt machine. The larger the mesh of the mesh, the lower the number of nets and the greater the amount of paste. It will cause the amount of paste to increase. When the amount of paste is large, the paper with low weight will shrink, and a pit phenomenon will be formed. As a result, the surface of the cardboard will be uneven, so it can be lowered by increasing the number of meshes. The amount of paste. Controlling the surface of the corrugated board is not flat. In fact, it is similar to the rib line. It is a feeling of bump. Generally, everyone feels the tension problem. In fact, this is only a part. Tension is important, but the amount of paste is also very important. The amount of paste can ensure the flatness of the cardboard. Cigarette paper can be divided into ribbed cigarette paper and ribbed cigarette paper. The lines on the ribbed cigarette paper are horizontal and vertical, and their main function is to improve the appearance and increase the air permeability. It is made of natural fibers such as hemp pulp or wood pulp, and filler materials such as calcium carbonate. It is also added with a small amount of additives, and ordinary paper is mainly made of wood pulp. In addition, there are some tobacco factories that are pondering the anti-counterfeiting of paper. When it comes to cigarettes, everyone is familiar. Put a 50 ml volumetric flask in an ice water bath, add distilled water to the flask, and mix the pyridine glacial acetic acid mixed solution in the cap bottle into the ice water rotated by the magnetic stirrer and the rotor under stirring. The machine recovered the precipitate and washed 3 times.

In order to improve the cleaning effect of the suction hole, the water spray pipe inside the vacuum roller of the large-sized, high-speed paper machine is designed to be reciprocally movable, and is cleaned using high-pressure water. The compact wet end system solves these problems by using a centrifugal degasser, a pressurized white water distribution system, and white water reuse to effectively reduce the size of the system.

Multifunctional Children's Study Table Chair Set

Myopia in young people is generally triggered by means of horrific habits in the getting to know process, such as incorrect sitting posture and bad lighting. The studying surroundings created through a excellent gaining knowledge of desk is nevertheless beneficial for stopping myopia, so purchase anti-myopia studying desks for children. let kids strengthen excellent learn about habits, which will accompany them for a lifetime. children goes to school, they can use the learn about table. The find out about desk on the market can modify the peak of the desk in accordance to the peak of the child. The learn about desk is an integral device for young people to do homework. For example, there is a incredible and good-looking find out about desk on the market. The feature is sensible lifting and lowering, and the computing device can be folded. , When a man or woman sits in the front of the table, they naturally enter the concave desk top, and the two hands stoop naturally. Because the two elbows are supported via the concave plate, the physique naturally does no longer lean forward, which correctly solves the shortcomings of mendacity on the belly to write and study. When buying for a find out about desk, be positive to maintain these must-have points in mind. The focal point of the learn about desk is to right the sitting posture and stop myopia, which is a foldable learn about desk with a concave desk top.
