Problems in papermaking technology

Since then, toilet paper has been used by consumers. Basically, the development of toilet paper market has a certain relationship with the production of our country. The growth of population and the growth of quality of life will affect the growth of toilet paper. However, according to the current situation, the production of toilet paper is increasing every year, and the consumption is also increasing.

The traditional single cylinder, open hood and the speed of less than 200m / min old tissue paper machine is gradually being eliminated by the market due to its low production capacity, large energy consumption and low profit margin. Under the requirements of eliminating backward production capacity, taking the low-carbon economy of energy saving and consumption reduction, and developing green industry, domestic tissue paper manufacturers have eliminated low-speed tissue machines with high energy consumption and high pollution, and replaced them with medium and high-speed tissue machines.

Nowadays, medium and high-speed domestic household paper machines (single large cylinder, diameter not less than 3600 mm) with width of 2500 mm ~ 4500mm and speed of 800 m / min ~ 1800 m / min have been widely promoted. This shows that China's paper industry has entered the transition period from the growth stage to the mature stage, and is in the process of structural adjustment, transformation and upgrading and seeking new balance.

At this time, about 94% of the pulp can be transferred from the drying section to the drying stage through the drying section, and then the drying process can be completed from the drying section to the drying stage, and then the drying process can be completed from the drying section to the drying stage Take out the roll.

High speed tissue paper machine has special structure and process requirements, and its control system is significantly different from the paper machine for producing cultural paper and industrial paper. Domestic paper equipment manufacturing enterprises have encountered great technical difficulties in the control of new toilet paper machine.

The conventional high-speed tissue machine equipment manufacturing enterprises usually only produce the mechanical device body of the paper machine, and the process flow and control system are generally commissioned by research institutes or automation technology companies.

However, the market competition and consumers' strict requirements for product quality make paper enterprises only adopt advanced control strategies and matching appropriate automatic control systems to achieve energy-saving and efficient production, and then strive for survival space and develop high-speed tissue machines. It is necessary to solve the problems of product quality, energy consumption and cost.

Although the overall demand and production of tissue has been increasing, but overall there is still overcapacity. For this situation, it is still necessary to put forward the corresponding requirements for the paper-making enterprises to improve the production rate and to better save energy consumption. For the paper industry, under the increasingly severe market competitiveness, Shandong yangke gas hood has also brought certain challenges and opportunities to enterprises
