Focus on Clean Development of Fastener Industry

To complete China's proposed "10th Five-Year" period of 10% emission reduction of the hard targets, in addition to grasping environmental education, really work hard; must also pay attention to details. To understand clearly where the requirements of this indicator come from, the relative density of pollution sources in the fastener industry is relatively small compared to some heavy industry polluted SARs, but it cannot be ignored. Although pollutant emission reductions do not have rigid targets for fastener companies, they must also assume some of their social responsibilities.

Compared with developed countries and regions, the overall level of the fastener industry in China has been improved to some extent in recent years, but the environmental awareness is still at a shallow level because of the level of people’s environmental awareness and is affected by various social factors. Constraints. Environmental awareness is reflected by people's environmental behavior.

Looking at the internal management of fastener companies, the level of environmental awareness is often higher than the level of environmental behavior, but in reality there is a "thinking giant, the dwarf of action," and pollution reduction is urgently needed. It is understood that the environmental situation of the fastener industry is still worth paying attention to, and it is particularly manifested in the problems of water pollution and pollutant discharge. The environmental problems that some old companies have accumulated over the long term need to be improved, and environmental issues of new start-up companies are also emerging.

At present, environmental problems in some local fastener companies have not been resolved for a long time, and the pollution rally has continued to escalate even further.

Such as hydrochloric acid mist pollution in the company's internal drawing process, phosphating solution, black liquor discharge in the surface treatment and pickling pollution of electrolytic galvanizing, alkali pollution, and oil smoke, noise, sewage, etc. Environmental pollution problems affect the lives of employees and people from time to time. Toxic and harmful gases can adversely affect the human nervous system, immune system, endocrine system and reproductive system, causing drowsiness, weakness, chest tightness, mental paralysis and allergies. Such as the phenomenon, whether there is hope for improvement, but also what to solve. Only by understanding this one-by-one detail problem can the global and overall issues be resolved more thoroughly and effectively.

It is difficult to do anything in the world. It must be done by Yi, and it must be done fine. Some seemingly minor, trivial, trivial matters, but ultimately affect the overall situation of environmental protection.

The continuous improvement of details and the actual implementation of specific measures are the basis and key to doing a good job in environmental protection and achieving the “Eleventh Five-Year” pollution reduction targets.

Fastener companies must attach great importance to environmental protection. They must accelerate technological innovation and institutional innovation, increase investment in environmental protection technology, strengthen pollution control within the company's area, promote cleaner production, and build a harmonious and sustainable development of fasteners for people and nature. We must really do a good job of managing details and protect the environment from the source, so as to effectively promote the sustainable development of the entire society.

A4 Paper Machine

This is A4 Paper Making Machine,writing and printing paper making machine.

1 1

According to the different paper grade and working speed, this kind of paper machine is needed to select the way of papermaking, dewatering structure of press section, dryer cylinder bank, sizing and finishing equipments.

 

Sheet forming can use the open-type headbox, air-cushion headbox, and hydraulic headbox, gap former and inclined wire former. According to the paper uniformity requirement, it can use distributor roll or finishing surface roll.

 

Press dewatering type is multi-roll and multi-press nip press rather than large-diameter press. As the low basis weight and wet strength of this kind of paper, it usually makes the low strength wet sheet attached to the felt or guide rolls during each section mutual transferring and full web leading as much as possible.

 

Dryer section: dryer cylinder group. Paper leading: active or passive paper rope system. Finishing equipment: To choose according to the paper grade requirement.

 

Now we introduce the technical proposal and structural drawing of Fourdrinier advanced printing paper machine, which we made for Taiqian Minrui Huatong Paper Company in Henan province, China. The advanced printing paper of this company is the famous brand in China.

 

Trimmed width: 2640mm

Working speed: 400m/min

Basis weight: 50-100g/sq.m.

Headbox: Air-cushion headbox

Forming table length: 15m

Suction flat box with all stainless steel micro-crystal cover.

Press section: four rolls two press nips

The wet sheet is stripped by pick-up suction unit.

 

The second under press nip rubber blind bottom roll diameter is Î¦800mm, with drive unit;

The suction top roll diameter is Î¦800mm, with drive unit.

The top press nip is made by a stone roll and a rubber roll. The rubber roll diameter isΦ800mm, with drive unit;

The stone roll diameter is Î¦850mm, with cut squirt.

This structure ensures the low strength wet sheet can press smoothly and paper breaks can be reduced.

 

The smooth press rubber bottom roll diameter is Î¦800mm; the top stone roll diameter isΦ850mm. The paper leading roll has the drive unit.

 

The dryer section has 32 dryer cylinders with the diameter of Î¦1800mm, which is divided into five groups: three groups for before-sizing, two groups for after-sizing. The top and bottom felt of first group and the group at the back of sizing machine is equipped with six felt drying cylinder with the diameter of Î¦1250mm, which can dry the moisture well and improve the drying efficiency.

 

The paper leading roll has the drive unit. The paper leading type is three-stage passive paper rope system.

 

Sizing machine: inclined type surface-sizing machine.

Calender: four roll three press nips; the number is decided by the demands.

Reeler: horizontal pneumatic reeling machine.
