What to pay attention to semi-refined paraffin
Semi-refined paraffin is also a PVC processing aid product. The semi-refined paraffin wax is a plate-like white solid. What should be paid attention to semi-refined paraffin?
The relative density of this PVC processing aid can increase as the melting point increases. The product has good chemical stability, moderate oil content, good moisture resistance and insulation properties, and good plasticity. Candles made from semi-refined paraffin wax are concentrated, smoke-free and free from tears. The processing of semi-refined paraffins on the market today is based on the implementation of GB/T 254-1998 national standards. Products that do not meet the national standards cannot be used. When we process PVC products, adding this PVC processing aid will have absolute benefits for the melting of PVC materials. Introduce the sexual use and precautions of this PVC processing aid: Semi-refinery can be applied to candles, crayons, wax paper, general telecommunications equipment, short circuit and light industry, and chemical raw materials. Semi-refining takes oil-wax as raw material, is deoiled by sweating or solvent, and then refined by semi-finished clay or hydrogenated to obtain semi-refined paraffin wax.
The use of semi-refined paraffin is noted as follows:
1. The quantity of molten wax should be suitable. The melting wax temperature should not be too high. Before the wax is melted, the wax block should be broken to accelerate the melting speed.
2. Semi-refined paraffin should be stored in a cool place. Do not expose it to sunlight. Store at a temperature that is not too high to prevent the wax from becoming soft and sticking to each other.
3. Storage and transportation of paraffin should be kept away from fire so as to avoid fire.
The above introduction is the use of this PVC processing aids precautions, let's take a look at the main uses of this paraffin:
Semi-refined paraffin wax can be used in candles, crayons, wax paper, general telecommunications equipment, short circuit and light industry, and chemical raw materials.
The PVC processing aid uses oily wax as a raw material, is subjected to sweating or solvent deoiling, and then refined by semi-finish or hydrogenation to obtain semi-refined paraffin wax.
