Abstract

The invention relates to a manufacturing process of an environment-friendly carton spacer plate. The manufacturing process comprises the process steps that 1, sludge is filtered, wherein collected paper making sludge undergoes filtration and impurity removal; 2, the sludge is concentrated, wherein the paper making sludge treated in the step 1 is input into a sludge sedimentation tank, cationic polyacrylamide accounting for 1-2% of the absolute dry weight of the paper making sludge is added into the paper making sludge, stirring is performed for 120-150 seconds at the stirring speed of 250-300 r / min, and then sludge gravity concentration is performed; 3, the sludge is dewatered, wherein the concentrated paper making sludge is dewatered by adopting a band type sludge filter press; 4, slurry is made; 5, the filter press is formed; 6, squeezing and drying are performed. The paper making sludge is used as a raw material to make the carton spacer plate and is resourcefully utilized, the problem of second pollution the paper making sludge is thoroughly solved, and land resources are saved. In addition, the manufacturing process is simple and low in production cost.

Description

technical field [0001] The invention relates to a manufacturing process of an environment-friendly carton gasket plate. Background technique [0002] The amount of sludge treated by papermaking wastewater is large, generally 5 to 10 times that of municipal sewage treatment plants of the same scale. According to the survey, the amount of sludge produced by pulp and paper enterprises in my country is about 5 million tons every year. At present, most of the treatment methods for papermaking sludge are dewatered by sludge dehydrators and then buried. This treatment method is expensive, wastes land resources and is prone to secondary pollution. Contents of the invention [0003] The object of the present invention is to provide an environment-friendly carton gasket manufacturing process with simple process and reasonable utilization of papermaking sludge. [0004] The object of the present invention is achieved through the following technical solutions: a manufacturing proces...
