According to the Notice of the Ministry of Science and Technology of Henan Province on the Approval of the Construction of the Provincial Key Laboratory of Henan Province in 2018 (Yuke [2018] No. 186), December 4, 2018, Zhengzhou Huajing Diamond Co., Ltd. and Henan The Electrical and Mechanical Vocational College jointly declared the “Henan Provincial Key Laboratory of Intelligent Manufacturing of Superhard Materials†and was approved by the Provincial Key Laboratory of Henan Province in 2018. Prior to this, Mr. Zhang Jianhua, deputy general manager of Huajing Company and related personnel participated in the defense review meeting organized by the Science and Technology Department of Henan Province.
It is understood that the provincial key laboratory of Henan Province is the Henan Provincial Science and Technology Department to thoroughly implement the innovation-driven development strategy, according to the "Henan Province Science and Technology Innovation Platform Construction and Management Measures (Trial)" (Yu Ke [2016] No. 83) and Relevant regulations on the construction and operation management of provincial key laboratories in Henan Province (Yuke [2016] No. 164), etc., recommended by the competent authorities, formal review, comprehensive review, on-site inspection, research and approval of the office of the director, public notice, etc. The program is determined.
Huajing Company and the Institute of Mechanical and Electrical Engineering intend to launch the “Henan Provincial Key Laboratory of Intelligent Manufacturing of Superhard Materialsâ€, which is positioned in the application basic research of intelligent equipment manufacturing integration of superhard materials, researching the manufacturing process and equipment technology of superhard materials. Intelligent monitoring and control technology for hard materials, large data acquisition and management and analysis application technology for superhard materials, information integration management technology based on Internet+, and digital integration technology for superhard materials intelligent equipment based on full life cycle process .

I. Introduction
Cationic Fixing Agent is polyelectrolyte, consists of a series of organic synthesis with low molecular weight and strong cationic, which is generally 100% cationic. Product character is aqueous solution.
II. Performance Indicators:
1. Appearance: colorless to pale yellow viscous liquid
2. Solid content: ≥ 50%
3. PH: 2 ~ 6
4. Viscosity: 50 ~ 200 mpa.s
III. Application Field
Used in paper pulp as a cationic fixing agent. Usually the slurry contains colloidal particles consisted of fiber materials, additives and water, which are with anionic charge and interfere the papermaking process, so it is also known as anionic trash; the interference is mainly in the following aspects:
1. Influence wet chemical additives` normal function, especially for cationic retention and drainage aids, sizing agent; or cause to increase the amount of wet chemical additives;
2. Deposits in the paper machine system; interfere the efficient papermaking process.
3. COD discharge of sewage systems, increasing the load on the sewage treatment plant. Recommended for use in mechanical pulp, chemi-mechanical pulp, and secondary fiber pulp slurry and coating waste stuff. Anionic trash neutralized by fixing agent can be bonded to the fibers so as to be taken away by paper sheets.
IV. Methods of Application
Adding methods: excellent water-solubility; can spread out in water instantly. Dosing pump is generally used to drive it into a static mixer or a mixing pump , mixed with water, diluted to about 0.2% of the dissolved solution, and then into the slurry system.
Adding point: the general adding point is in the front of flow system, that is, before the machine chest or fan pump; or add in the pulp plant. Which is taken into consideration for the reaction time of the cationic fixing agent polymer molecules and garbage, also need to time and space for other wet end additives. According to the slurry source, sometimes you need to select two or more points to add. When the slurry contains a source of coated broke, generally requires additional anionic trash Fixative in the transport of the paper sheet.
Adding dosage: anionic trash content in the slurry is usually gauged by the cationic charge contents measured by PCD (particle charge analyzer) in the slurry. The measure will directly show the dosage tips, but the real dosage depends on the practical application. For general slurry, the recommend amount is in the range of 0.3kg ~1.8kg/t dry pulp.
V. Safe Operation
1. Cationic fixing agent is a water-soluble polymer, dissolved in water in a highly slippery state and avoid to spill on the floor. If spill, shall timely absorb with sand, sawdust.
2. Wear gloves, wear overalls to operate.
VI. Storage
The product should be kept sealed, stored in cool, dry, ventilated places, and appropriate temperature should be 10-30 ℃.
VII. Package
200 kg plastic drums or 1000 kg PE IBC drum.
