The petrochemical industry is my country's pillar industry. Petrochemical industry is also the cornerstone of other industries. Products touch all aspects of people's lives, such as gasoline, sulfur, plastics, rubber, fibers, chemicals, and so on.
In the process of production, packaging, transportation, and storage, barrier properties are the physical properties that the petrochemical industry often pays attention to. Barrier properties include water vapor transmission rate, oxygen transmission rate, gas or other toxic and volatile gases, etc., which are materials that block external humidity , Oxygen or prevent the volatilization of product gas, to ensure that the product is not polluted by the environment, or the important physical properties of the environment. Such as petroleum transportation pipelines, paints, plastic packaging, rubber tires, etc., all have strict requirements on water vapor transmission rate or gas transmission rate.
Xitang Technology is fully deploying barrier performance testing technology.

Evaporating Residue, Non-volatile Residue
2021-09-01
Pharmacy is a very rigorous process, and the quality of water has a major impact on the quality of pharmaceuticals. Ordinary water contains many trace elements and other substances, which cannot meet the needs of pharmaceutical production. Only purified water that meets the requirements can be used in pharmaceutical production. In this regard, the state has formulated a number of testing items to monitor the quality of purified water, and "non-volatile matter" is the most "torturing" item. The "most tortured" person in non-volatile matter testing? According to the Pharmacopoeia, 100ml of purified water is placed in an evaporating dish with constant weight to evaporate to dryness, and after drying to constant weight, the remaining residue shall not exceed 1mg; in addition, according to the general requirements of the Pharmacopoeia, the constant weight needs to be dried twice and weighed. The difference is less than 0.3mg. The 0.3mg constant weight requirement is very difficult for manual operation, so too many experimenters always struggle with this, and they think that the non-volatile item is too torturous. How to solve this "torture" problem? In today's increasingly high degree of automation, Xitang Technology has given the answer-a non-volatile constant weight meter. The constant weight instrument developed and designed by Xitang specifically to meet the requirements of constant weight, integrates the functions of water bath evaporation, heating and drying, drying and cooling, and constant temperature weighing. Instead of traditional water bath, oven, drying oven and balance, 2 weighing processes can achieve constant weight weighing. It not only perfectly meets the requirements of the standard 100%, but also greatly improves the efficiency of constant weight and the accuracy of the experiment. At this point, the "torturing" experiment is no longer tortured, the experimenter only needs to install the sample, and the rest is handed over to the automation. At present, more than ten listed pharmaceutical companies have applied the constant weight instrument for quality inspection. The constant weight instrument in the pharmaceutical industry can also be applied to: non-volatile matter in extracts of pharmaceutical packaging materials, loss on drying of raw materials, extracts of traditional Chinese medicines, and other constant weight requirements experiments. Purified Water Non-volatile Residue Constant Weight Tester——Relative Products: Constant Weight Tester 12 specimens, integrated the functions of evaporating, heating, drying, constant temperature weighing. Constant Weight Tester 23 specimens, integrated the functions of evaporating, heating, drying, constant temperature weighing.
