1. Product Overview:
LH-67SG macroporous adsorption resin is a copolymer of divinylbenzene and methyl acrylate, which has the characteristics of large exchange capacity, small volume change, high mechanical strength, good chemical stability, anti-pollution, oxidation resistance, fast exchange speed, etc., such as the extraction and separation of stevia, and also has a good effect on the treatment of chemical and industrial wastewater and waste liquid, and the recovery and purification of chemical products.
2. Product technology index parameters:
1. Appearance: milky white to light yellow opaque spherical particles
2. Adsorption capacity for sweet leaves: ≥9
3. Particle size range: 0.3~1.25mm (20~60 mesh) ≥90%
4. Wet vision density (g/ml): 0.65~0.75
5. Water content: 65~75%
3. Product characteristics:
1. The color is milky white to light yellow to bring convenience to the processing operation, and the separation and purification of colored organic compounds are easy to observe.
2. Stable physical and chemical properties, insoluble in any acid, alkali and organic solvents, convenient for the selection of adsorbents and desorption agents. High temperature resistant and can be used below 150°C.
3. Good selectivity for organic matter and not affected by the presence of inorganic salts, such as the removal of high-grade fatty acid lipids from wine.
4. Easy to regenerate, the regenerator can be water, dilute alkali, dilute acid or low boiling point organic solvent. Such as: methanol, ethanol, acetone, etc.
5. Moderate strength and long normal service life.
4. Precautions:
1. The resin has a large water content, and the temperature should be maintained at 5-40 °C for storage and transportation to prevent the spheres from freezing and cracking at low temperatures and mildew at high temperatures, which will affect the use.
2. The resin should not be directly injected with water due to exposure to air or water loss for any reason, so as not to float the resin, and can be impregnated with ethanol to restore the wet state, and then washed with water.
3. Industrial-grade commercial resin must be pretreated before use, and the net resin can be used directly, and it can be soaked and rinsed with ethanol or double distilled water before safe use.

5. Packaging:
PE bag lined with plastic bag 25kg
