Test standard and test item of semi-refined Kunlun paraffin

Semi-refined paraffin is a common raw material mainly used in the detection of paper packaging materials and candles. Of course, as an important chemical product, it is also widely used in chemical raw materials, textiles, light industry, cultural and educational supplies, wood processing and telecommunications materials.

Semi-refined paraffin is mainly made of oily wax as raw material, through sweat treatment or solvent deoiling, and then through clay or hydrorefining products. Compared with fully refined paraffin, semi-refined paraffin has lower refining degree and higher oil content, so it is different in color, penetration degree and light stability.

But semi-refined paraffin has good sealing, insulation, plasticity and lubricity characteristics, at the same time, can play the role of moisture, rust, aging, volatile drying, deformation and insulation. So semi-refined paraffin is often used for combustion, combustion, lubrication, adhesion and plasticity functions.

Let's go back to the title question. First of all, we should know that as long as the supply and demand sides reach an agreement, the enterprise can not organize production according to the national standards. There is no problem that enterprises can supply products according to the demands of the demand side.

China is a large country producing semi-refined paraffin and exporting it. Relatively speaking, there are few foreign products produced. The current national standard GB/T 254-2010 "semi-refined paraffin" has been nearly 10 years since the last revision, and the domestic production situation has already undergone great changes.

Especially new product indicators, international product standards have also had new requirements. In the past 10 years, the raw materials of paraffin wax have also changed. Some production enterprises have been unable to obtain paraffin-based crude oil, which leads to the gradual change of raw materials of paraffin wax production.

Therefore, in the face of GB/T 254-2010 technical requirements, many enterprises choose to refer to this standard, to develop their own enterprise standards. Many purchasers also directly skip GB/T 254-2010, more recognized enterprise standards or their own specified index requirements, which makes semi-refined paraffin detection in the face of a very awkward situation.
