[0076] Preparation Example: Preparation of Modified Calcium Sulfate Whiskers

[0077] A1: Cut the calcium sulfate whiskers to a length of 0.3mm, add them to a sufficient amount of absolute ethanol, ultrasonically clean them for 25 minutes, filter, wash the calcium sulfate whiskers with deionized water for 2-3 times, and remove them. , fully dried to obtain clean calcium sulfate whiskers;

[0078] A2: Add clean calcium sulfate whiskers to dehydrated alcohol of 9 times its mass, then slowly add the dehydrated ethanol solution of isopropyl orthosilicate (the clean calcium sulfate whiskers and isopropyl orthosilicate The mass ratio of the isopropyl orthosilicate is 1:0.5, and the mass percentage concentration of the isopropyl orthosilicate is 25%), stirred and reacted for 50 minutes, filtered, and the obtained whiskers were fully washed 3-4 times with deionized water, dried, and The obtained dried whiskers were calcined at 320° C. for 35 minutes, and cooled naturally to room temp...

Embodiment 1

[0080] S1: According to the weight ratio of 2:1:1, weigh phenol A type epoxy resin, methacrylic acid-butadiene-styrene terpolymer (MBS resin) and polyvinyl chloride, and use a high-speed mixer to carry out Fully and evenly mixed to obtain 80 parts by weight of resin masterbatch;

[0081] S2: Add 1 part by weight of the modified calcium sulfate whisker obtained in the preparation example, 1 part by weight of the stabilizer isooctyl dimethyl tin dimercaptoacetate, and 3 parts by weight of the toughening agent methyl methacrylate into the above resin masterbatch -butadiene-styrene terpolymer (MBS), 0.4 parts by weight of nano carbon black, 3 parts by weight of dilaurate thiodipropionate, 1 part by weight of two-component antioxidant (for mass ratio 1: 1 Tris(2,4-di-tert-butylphenyl)phosphite and 1,3,5-trimethyl-2,4,6-tris(3,5-di-tert-butyl-4-hydroxybenzyl base) benzene mixture), 0.8 parts by weight of adhesion promoter formula (I) compound, 6 parts by weight of auxiliary agent (...

Embodiment 2

[0084] S1: According to the weight ratio of 2:1:1, weigh phenol A type epoxy resin, methacrylic acid-butadiene-styrene terpolymer (MBS resin) and polyvinyl chloride, and use a high-speed mixer to carry out Fully and evenly mixed to obtain 80 parts by weight of resin masterbatch;

[0085] S2: Add 0.5 parts by weight of the modified calcium sulfate whisker obtained in the preparation example, 2 parts by weight of the stabilizer isooctyl dimethyl tin dimercaptoacetate, and 2 parts by weight of the toughening agent methyl methacrylate into the above resin masterbatch -butadiene-styrene terpolymer (MBS), 0.8 parts by weight of nano carbon black, 2 parts by weight of dilaurate thiodipropionate, 1.6 parts by weight of two-component antioxidant (for mass ratio 1: 2 Tris(2,4-di-tert-butylphenyl)phosphite and 1,3,5-trimethyl-2,4,6-tris(3,5-di-tert-butyl-4-hydroxybenzyl base) benzene mixture), 0.5 parts by weight of adhesion promoter formula (I) compound, 8 parts by weight of auxiliary ...

Abstract

The invention discloses a novel water ring vacuum pump and belongs to the technical field of liquid pumps. The water ring vacuum pump comprises a pump body. A water ring rotor is rotatably mounted in the pump body. The top of the pump body is provided with an air inlet and an air outlet. One side of the pump body is provided with a working fluid inlet and a working fluid outlet. The working fluid inlet is connected with an impurity removal box. The impurity removal box is provided with an airtight impurity removal cavity. The impurity removal box is provided with a liquid inlet and a liquid outlet which communicate with the impurity removal cavity. The liquid outlet is connected with the working fluid inlet. A plurality of hollow pipes penetrating through the impurity removal cavity are arranged on the impurity removal box. The two ends of each hollow pipe are open and do not communicate with the impurity removal cavity. A permanent magnet is inserted into each hollow pipe. The water ring vacuum pump has good industrial application prospects and industrial production potential.

Description

technical field [0001] The invention relates to a pump, more particularly to a novel water ring vacuum pump, which belongs to the technical field of liquid pumps. Background technique [0002] The water ring vacuum pump realizes suction, compression and exhaust by changing the volume of the pump chamber. Therefore, the water ring vacuum pump belongs to the variable capacity vacuum pump. [0003] Due to the excellent performance of water ring vacuum pumps, water ring vacuum pumps are widely used in many industrial processes, such as vacuum filtration, vacuum water diversion, vacuum feeding, vacuum evaporation, vacuum concentration, vacuum moisture regain and vacuum degassing. At the same time, due to the rapid development of vacuum application technology, the water ring vacuum pump has been paid attention to in terms of vacuuming. Because the gas compression in the water ring vacuum pump is isothermal, it can pump out flammable and explosive gases. Extract dust and water-co...
