Wet Penetration Tester

 Application:

Protective Clothing Tester Wet Microorganism Bacterial Penetration Resistance Tester Apparatus: used to measure the penetration performance of bacteria in the liquid when the material is subjected to mechanical friction (the shielding performance of the liquid against bacterial penetration by the mechanical friction chamber)
 
Standards:
EN ISO 22610, EN 14126, Annex A, YY/T 0506.6
 
Feature:
Automatic stop as preset counters.
High stable testing performance from precise structure design.
Stainless steel body provides high corrosion resistant performance.
Adjustable loading pressure.
 
Specifications:
Rotary speed: (60 ± 1)rpm
The test refers to the pressure on the material: (3±0.02)N
Outward wheel speed: 5~6 rpm
Timer set range: 0~99.99min
The inner and outer ring weights: (800±1)g
 
Principle:
Place the specimen on AGAR plate. A piece of the same specification is placed on the specimen. Cover with a high density polyethylene film about 10 microns thick.  The three layers of material  using the cone steel ring (the test material below, the mushroom center, high density polyethylene film on top) are stuck together. Place the ring on the AGAR plate on the turntable. The experiment means that the material can be applied to the material in a way that can be moved on the surface of the whole plate, so that the material is subjected to the combination of pressure and friction. 
This model can simulate the force condition of the barrier material in the actual application and the microorganism penetration under the wet conditions.
The microbes on the microbial migrate to the surface of the AGAR plate after penetrating the experimental material. Through the culture and colony count of AGAR plate, the penetration performance of the test material can be quantitatively evaluated.

The Leather Friction Color Fastness Tester

Leather friction color fastness tester applied to test leather property in shoes, clothing, luggage handbag industry, research laboratories; commodity inspection, arbitration and technical supervision departments.Leather friction color fastness tester test the degree of decolorization of dyeing leather after friction. It can used to test the leather color resistance to dry, wet and friction. This instrument is suitable for leather, textile, belt, trademarks, cardboard and other friction materials by foreign object damage and decoloring. The machine is designed to carry out a rub fastness test on the surface of leather or coated fabrics to determine the marring of the surface finish and to assess the amount of color transfer from the sample to the rubbing pad. This machine is designed to determining the colorfastness of leather, plastics and textile materials. The colorfastness is assessed by checking change in color of the specimen and stain of the felt after rubbing the ...

How Sublimation Fastness Tester Works?

Sublimation Fastness Tester is a suitable instrument for dyestuff manufacturers as well as textile processors for checking effects of dry heat on dyestuff. Qinsun-lab offers Sublimation Fastness Tester of the best quality and at the best price which gives accurate results.    Features of Sublimation Fastness Tester : Testing the effect of direct heat on the dyestuff； up to 250°C temperature range； Independent digital timers with the minimum display of 1℃(one with each of top and bottom plates, respectively)； Can test entire range of temperature in a single test.                           Working Principle: A dyed cloth piece is sandwiched between two undyed pieces and placed to cover the heat pads and the test goes on for a preset time period. The fabric pieces should be picked up immediately. The undyed fabric pieces will be stained by the dyes. This gives the sublimation fastness ...

what is the Working Principle of fogging tester?

Fogging Test Chamber   is the best tool to determine the fogging characteristics of automotive or other vehicle interior materials. The fogging tester is applicable for gravimetric method, photometric method and haze measurement method. Working Principle: The main frame of the Fogging tester includes a water sink fully filled with specified ethylene glycol, which can reach a high temperature. At the time of testing, leather specimens are put in the six standard glass containers filled with  high temperature liquid, and the stainless steel containers are placed above each glass. Relying on the constant water flow distribution, the temperature can maintain at 20℃ constantly, and it can be adjusted through the regulation device connected to the main frame. This controlled environment condition will generate a layer of “fog” on the surface of specimens. The operator can determine the fogging characteristics of materials based on gravimetric analysis method or refraction...
