Siam Kraft paper board factory renovation wet end squeezing promote sustainability

Siam SCGP in the beautiful scenery of Kanchanaburi province board factory, has been committed to achieve sustainability, cost efficiency and circular economy.As part of the SCGP company Wangsala complex, Siam board factory production of double-sided coated white board paper, suitable for offset printing.

SCGP is one of the top companies in the asia-pacific region, is famous for the sustainable development of its business operations.To follow the footsteps of the parent company, Siam
Cardboard factory has been committed to the sustainable and cost-effective operation and circular economy.

However, as the representation of the production level of printing paper factory, Siam cardboard factory 9 machine press section has been trapped by wet mark paper disease
Are the one.

"Wet mark paper disease problem is found in a routine on-site visit."D virtue southeast Asia Thailand service sales manager Kengkarn Jangsatiansuk said.

Dimensional virtue Laem Chabang expert service, can be through in-depth study on virtue of wet crushing solution to cope with the challenge of the customer

Obviously, because of the fiber, excess chemicals and other raw materials and energy consumption, as well as the continuous wet mark paper disease problems, hinder the sustainable development of the plant goals, leads to higher operating costs, shorter roller replacement and maintenance cycle."He continued."Plant expects us to provide optimizing press section performance and sustainability of the solution."

Three steps to improve the performance of press section

D virtue in Thailand Laem Chabang service center with Siam Kraft paper board factory has a long history of cooperation.Their experts through in-depth research, combining d virtue wet end squeezing solutions to cope with the challenge.

"Paper traces can be physical nicks, also can be streamlined traces, is presented in the paper the shadow or concave trace."YutthaponSittiwatjana paper technology manager said.

"Paper traces of either physical indentation, either is a fluid traces, traces on paper show the shadow or depression."D virtue southeast Asian papermaking technology managerYutthapon SittiwatjanaExplains, usually in the form of fluid imprinting in pressure area, such as high water load or not suitable for the fabric design under the compression state of melt water shortage caused by factors such as volume.In addition, the squeezing roller roller surface heterogeneity, fleece tight or fleece large humidity in the process of running, even for specific pressure area conditions, too hard roll bag rubber could lead to the problem."

In order to improve PM9 paper machine press section performance, dimensional virtue service experts to carry out a three-step plan, in order to understand the cause of wet mark paper disease problems, and to determine the right solution.

Step 1

Through water balance, the study found the press section pressure zone and fleece suction box water removal ability is enough.Determine the wet marks from the vacuum press roll paper agents.

Step 2

Based on dimensional virtue of wet crushing solution, vacuum Press Roll adopts Valmet Press Roll Cover PK bread Roll adhesive technology.

Step 3

Through the vacuum system, the study found the existing vacuum system has enough ability to guarantee the vacuum system requirements.

The study also found that the future can be modified through further optimization of press felt and roll shell type drilling to reduce the sensitivity of the wet mark problem.

The statistical results of three months

Vacuum squeezing roller is the main reason of disease of wet mark paper, so was the key to optimizing reconstruction.First, change the vacuum Press Roll plastic bags to more soft Valmet Press Roll Cover PK cladding layer, the cladding layer has a low load line, Press section uniformity good advantage.Low load line pressure can reduce the sensitivity of the wet mark paper disease.More durable polyurethane coating material to replace rubber coated material, implements the cladding mode of grooves, the blind hole processing, to ensure the water more efficiently Removal performance.

Now, after three months of the transformation, the vacuum press roll plastic bags after redesigning the implementation effect exceeded expectations.Solve the wet asked mark paper disease
The problem, the factory benefits.They have to realize the native fiber consumption from 24 g/m2 to 19 g/m2.Always fiber consumption has also dropped, it also improved the reliability and quality and maintenance.In addition, the soft calender roll grinding interval period from 30 days to 40 days, these are all benefit from the lower total quantitative, controllable thickness and higher smoothness.

Wet end squeezed onto the road of sustainable development

PM9 of Siam Kraft paper machine results proved that even the most serious problems in the production, can also be addressed by the correct solution.Sometimes change the balance of the water in the press section or pressure area is one of the effective methods to solve the wet mark paper disease;The secret lies in choosing the right sometimes
Consumable materials.

With the aid of dimensional virtue wet crushing solution, pulp and paper industry factory can rely on a wide range of professional products and services.For Siam Kraft paper board factory, have to do is an effort to solve the main problems of wet mark paper disease.Using Valmet Press RollCover PK redesign vacuum Press roll plastic bags, not only solved the problems of wet paper disease for a long time, but also by reducing fiber consumption, help the factory to achieve the sustainability, cost effective and the goal of circular economy.
