Précision : Classe 1


Plage de débitmètre de détection d'efficacité de dépassement : 10-100 L/min


Précision du débitmètre : classe 2,5


Fréquence d'échantillonnage : 1-9999 fois/min


Efficacité de filtration Concentration de particules : 20-30mg/m3


Diamètre médian de comptage : particules de sel (0,075±0,02) μm, particules d'huile (0,185±0,02) μm


Écart-type géométrique de la distribution granulométrique : particules de sel≤1,86, particules d'huile≤1,60



Plage de détection dynamique : 0,001-100 mg/m3, précision 1 %


Alimentation hôte : 220VAC 50Hz


Poids net de l'unité principale : 64 kg


Configuration de l'instrument : hôte, ordinateur, logiciel professionnel, générateur d'aérosol, compteur de particules de poussière laser, débitmètre à rotor en verre, pompe à vide


Principe du test : la détection de l'efficacité de la filtration consiste à pénétrer en continu dans l'élément filtrant avec des particules de concentration et de distribution granulométrique spécifiées sous un certain débit d'air, et à mesurer l'efficacité de la filtration de "chargement", c'est-à-dire de simuler le processus d'utilisation réel , la matière particulaire a une certaine quantité sur le matériau du filtre Efficacité dans l'état de dépôt (capacité de rétention de la poussière).

Tinuvin 1130: An Excellent UV Absorber

 In the field of the chemical industry, UV absorbers play a crucial role, particularly in protecting materials from UV damage. Today, we will delve into a highly regarded UV absorber—Tinuvin 1130. Tinuvin 1130 : chemical name: 3-(3-(2H-benzotriazole-2-yl)-4-hydroxy-5-tert-butyl phenyl)propionic acid polyethylene glycol 300 ester; CAS login number: 104810-48-2. This product is an exceptional UV absorber that offers numerous benefits due to its unique properties. One of the standout features of Tinuvin 1130 is its excellent weather resistance. It has a strong ability to absorb ultraviolet rays, particularly those with wavelengths ranging from 290-400nm. This effectively prevents coatings, plastics, rubber, and other materials from being damaged by UV rays, thereby maintaining the performance and appearance stability of these materials and extending their service life. In addition, Tinuvin 1130 exhibits good compatibility. It is easy to emulsify in water-based systems and can be...

Mechanism of action of benzonitrile

  Product identification: Product name:  Benzonitrile Molecular formula: C7H5N CAS No.100-47-0 Benzonitrile is a colorless oily liquid with an almond-like odor. It is slightly soluble in cold water, soluble in hot water, and easily soluble in organic solvents such as ethanol and ether. The mechanism of action of benzonitrile can be elaborated from the following aspects: I. Chemical Properties and Applications As an Intermediate in Organic Synthesis: Benzonitrile plays a crucial role in chemical synthesis as an intermediate for many important compounds and materials. For example, it can be used to synthesize advanced coatings such as phenyl melamine, as well as compounds such as pesticides, aliphatic amines, and benzoic acid. These compounds have a wide range of applications in agriculture, coatings, plastics, and other fields. As a Solvent: Benzonitrile possesses good solubilizing properties and can be used as a solvent. In organic synthesis, it is often used as a solvent to d...

Air-cooled Xenon Lamp Aging Tester

  The air-cooled xenon lamp aging tester is a device that uses an air-cooled system to dissipate heat and a xenon lamp to simulate ultraviolet light, visible light and infrared light in natural sunlight to perform accelerated aging tests on materials. It is commonly used in industries such as automobiles, coatings, plastics, rubber, and textiles. It can evaluate the aging resistance of materials under the combined effects of long-term light, temperature, humidity and other environmental factors in a relatively short period of time, helping companies improve product quality, extend service life, and optimize product anti-aging formulas and processes. Structural composition:  The main body is a test chamber, equipped with a xenon lamp and a matching optical filter system to simulate sunlight of different wavelengths, as well as temperature, humidity, lighting time and other control and adjustment devices, as well as an observation window and a sample rack. Working principle: The...
