Today, we will bring you some points for attention in using deoxidizer. We hope that through our introduction, you can have a deeper understanding of the problems of Zhengzhou Dongsheng Metallurgical New Materials Co., Ltd. and so on:

(1) Choose packaging materials with oxygen permeability less than 20 ml/m2.24h.25 C, such as KOP/PE.KPET/PE composite film packaging bags, plastic cans, glass cans, iron cans; 88811 1 (2) Attention should be paid to the sealing strength and quality, so as not to leak air;

(3) After opening this package, it is best to use up and seal the fresh-keeping materials within 1 to 2 hours, if not used up, please discharge the air in the original packaging bag in time and re-seal the use of deoxidizer to avoid failure;

(4) not microwave. Not edible.

may be of interest to you. The main function of riser is to compensate the shrinkage of liquid metal in the cavity and the shrinkage of casting during solidification, so as to obtain compact castings without shrinkage holes. When the casting is cooled in the mould, the thinnest part solidifies first, and its shrinkage can be compensated by the thicker part nearby; when the thicker part solidifies, it can be compensated by the thickest part. When the thickest part solidifies, it will form large shrinkage holes. Riser types:

. Common risers: common risers made of common moulding materials are called common risers;

2. Insulation risers: the main function of the riser made of thermal insulation materials is called heat preservation riser, and the liquid metal in the riser is better than that in the ordinary riser when solidifying. Heating riser: adding heating agent into riser material, after pouring liquid metal, the heating agent reacts to heat, so that liquid metal can stay in liquid for longer time, saving more metal than insulating riser.
