Medical mouth mask flame retardant property tester operation process

Medical mouth mask flame retardant property testerInstrument characteristics：


1. The mask fixture is a metal human head mold, which can simulate the actual use situation of the mask.


2. The burner is equipped with a combustible gas interface, such as propane (liquefied gas).


3. Burner height is adjustable.


4. Burner could be timing and positioning automatic.


5. Burning time and flame retardant time are automatically recorded and displayed digitally


6. Mask Flame Retardant Tester is equipped with flame temperature measuring probe and flame temperature display.

Medical mouth mask



Medical mouth mask flame retardant property tester operation process:

1. Plug in the power socket on the back cover of the instrument to turn on the power supply, connect the air inlet to the propane bottle, and open the gas bottle valve to connect to the gas source.


2. Close the front door of the combustion test chamber, and put the "power" switch to the "on" position, the power indicator light is on.


3. Turn the nose tip of the metal head mold down, bring the meltblown filter material on the metal head mold, and move the head mold with a little force by hand. When the nose tip of the head mold is just above the igniter, adjust the height of the igniter head (Rotate the igniter head clockwise to lower, and rotate the igniter head counterclockwise to raise) so that the distance between the top of the igniter and the nose tip of the head mold is 20±2mm.

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...

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...

The Structure of Hexapod Tumble Tester

The Hexapod Tumbler Tester is a popular apparatus used in the evaluation of the appearance retention of carpets. Drum – constructed of Nylon or other like material and capped by a lid that is secured by a latching device. The drum and lid have a locating groove to hold the specimen backing sheet flat to the inner wall of the drum. A photograph of a typical drum is show in Photograph 1 and Photograph 2. The drum dimensions are:   Internal Diameter: 12 ± 0.18 in. (302 ± 5mm) Wall Thickness :0.3 in. approx. (8 mm approx.) Internal Depth: 8.2 ± 0.2 in. (207 ± 5 mm)  Driving System - cradles the drum on rollers and keeps the axis of the drum level, and rotates the drum at 35 ± 2 rpm (3.6 ± 0.2 rad/s). The driving direction reverses after approximately 500 revolutions.  After the 500 rotations the unit will stop and stand stationary for approximately 5 to 15 seconds, then begin rotating in the opposite direction. After 2000 rotations the unit will stop and w...
