[0003] (1) The guide slope is directly processed on the top of the main beam. The problem is that the processing cost is high and the guide surface has no anti-corrosion measures;
[0004] (2) The stainless steel sheet is folded, and the problem is that the cost is high and there are seams;
[0005] (3) Steel guide rails are installed on the upper part of the main girder. The problem is that the cost is high and it is not anti-corrosion
The plastic product made by this formula has compact material and high hardness, but the wear resistance is not high enough, so it is not suitable as special guide rail plastic for filter press.

Embodiment 1
[0053] Prepare raw materials according to the following parts by weight:
[0061] According to the above formula, the specific processing method is as follows:
[0062] (1) Filler activation: In order to improve the combination of filler and polymer, the filler is activated with a coupling agent. First, add the filler to the high-speed mixer, stir, preheat and dry for about 10 minutes, and maintain the temperature at 90~110°C; then add the coupling agent evenly in three times, with an interval of 2 minutes between each addition, and stir evenly after each addition. After adding the coupling agent three times, continue to stir for 10 minutes and dischar...

Abstract
The invention discloses guide rail plastic special for filter presses. The guide rail plastic comprises the following raw materials in parts by weight: 100.0 parts of polyvinyl chloride (PVC) resin, 100 to 150 parts of filler, 0.3 to 0.5 part of surfactant, 2.5 to 5.0 parts of coupling agent, 0.5 to 0.8 part of heat stabilizer, 0.3 to 0.5 part of antioxidant, and 0 to 2 parts of pigment. The invention also discloses a processing method for the guide rail plastic special for the filter presses. The method comprises three steps, namely filler activation, granulation and processing forming. By adopting the formula and the processing method for the plastic, the guide rail plastic special for the filter presses can be obtained; and the properties of the guide rail plastic special for the filter presses, such as hardness, abrasion resistance and the like are greatly improved, so that plastic guide rails can be applied to large-sized filter presses.
Description
technical field [0001] The invention relates to a plastic, in particular to a special guide rail plastic for a filter press and a processing method thereof. Background technique [0002] Generally, the main beam of the filter press is equipped with a guide mechanism to guide the movement of the filter plate. The guide mechanism mainly has the following methods: [0003] (1) The guide slope is directly processed on the top of the main beam. The problem is that the processing cost is high and the guide surface has no anti-corrosion measures; [0004] (2) The stainless steel sheet is folded, and the problem is that the cost is high and there are seams; [0005] (3) Steel guide rails are installed on the upper part of the main girder, which has the problems of high cost and no corrosion protection. [0006] In response to these shortcomings, the patent document with the authorized notification number CN2617451Y discloses a special guide rail for filter presses. The main beam i...
