paper machines may encounter various problems in the production of paper, which are all caused by different factors. as long as the factors that cause the problems are identified during the production process, the problem can be solved calmly and appropriately. the possible reasons for the occurrence of coarse lines in paper production by paper burning machines are: improper mixing of materials and additives in pulping or papermaking, low solubility, improper blade angle in papermaking, excessive steam consumption, and alkaline white water, which may all cause coarse lines.
once the cause of the occurrence is found, it is easy to find a solution to the problem. if it is caused during the paper making process, methods such as controlling steam consumption, replacing rollers, and adjusting the angle of the scraper can be used; if it is caused during the pulping process, measures such as increasing the grinding concentration and beating degree reasonably, beating according to the proportion, and applying additives can be taken.
