A Diagram Instruction of Glow Wire Test Method for Electrical Appliances

 A Diagram Instruction of Glow Wire Test Method for Electrical Appliances You may be a bit of a stranger when it comes to the IEC(International Electrotechnical Commission), but when it comes to the glow wire (GWT) test, everyone in engineering plastics should have heard about it. We will use diagram to introduce glow wire test which is very normal for electrical appliances. And we will focus on the three subjects below: 1.What kind of product needs GWT testing? 2.Test equipment and related facilities for the GWT testing. 3.What are the GWIT, GWFI and GWT test method? The scorching wire test is a mandatory test for unattended electrical appliances. Its standards and testing methods are formulated by the IEC, which is one of the important standards for the export of electronic products to the European market. Please note: this test is mainly for products sold in the European market, as the IEC is based in Europe (Geneva, Switzerland) rather than the United States. The GWT we mention...

How does the Leather Abrasion Tester determine the performance of leather?

How does the Leather Abrasion Tester determine the performance of leather? Leather Abrasion Tester is used to test the abrasion resistance of leather. The abrasion of leather is an important cause of leather damage. 1. Judgment method There are two methods to judge the leather wear resistance index, namely the end point method and the appearance change method. 1.1 end point method: grinding away lmm leather required to rotate the number of times for the thickness index of wear resistance, write down the number of friction rotation as the wear resistance index. 2. Flat abrasion test method Test apparatus: There are many kinds of fabric flat abrasion instruments, and the one that is used a lot in the testing industry at present is  Martindale Abrasion Tester , so the flat abrasion method is also often called MARTINDALE friction tester method.  According to the total number of friction of the specimen broken, to determine the wear resistance of leather.

How to quickly improve the color fastness of leather textile fabrics to rubbing?

How to quickly improve the color fastness of leather textile fabrics to rubbing? 11 feasible countermeasures to improve the color fastness of leather textile fabrics to rubbing. (1) pay attention to the screening of dyestuff, use those good solubility, combined with a good quality dyestuff, when the conditions allow, it is best to use metal complex dyestuff and alcohol-soluble dyestuff, as little as possible to use acid dyestuff. (2) Before dyeing, we must remove the dust and chips on the leather surface. (3)The color should be dyed as accurate as possible, avoid spray dyeing and color mixing afterwards. (4) When dyeing or top dyeing, the dyeing temperature should be controlled in a high range, generally to 60~65 ℃. When using low temperature dyeing with small liquid ratio, the temperature can be warmed up by replenishing water at the later stage of dyeing, and finally the temperature should be controlled at 60~65 ℃. (5) When formic acid fixing, there should not be more remaining uncom...

3 Ways Tips to Improve Leather Washing Colour Fastness

3 Ways Tips to Improve Leather Washing Colour Fastness How to improve Leather Washing Colour Fastness? After washing or soaping, the area, skin shape and color will not change significantly, and the fullness, elasticity, softness, physical strength and shrinkage temperature will not deteriorate significantly. In order to make the washable leather have the above performance characteristics, the processing must do "three solid combination". (1) Tanning agent and leather fiber are firmly combined. Only when the tanning agent is firmly combined, the leather will not be tanned after washing or soaping, so that the area of the leather will not be obviously reduced and the shape of the leather will not be obviously changed, and the fullness, elasticity, softness, physical strength and shrinkage temperature will not be obviously reduced. (2) The fatliquor is firmly combined with the leather fiber. Because only when the fatliquor is firmly bonded, the grease will not be washed off in ...

Test conditions and test analysis of the Cone Calorimeter - News - -standard groups (Hong Kong) co., LTD

Test conditions and test analysis of the Cone Calorimeter 1. Preparation of sample pieces Conical calorimetry test sample pieces, should be intact, uniform material quality, the size of 100mm × 100mm square, the thickness of 3 ~ 20mm, commonly used thickness of 4, 10mm.   Sample parts can be pressed with a mold, or cut from the finished sheet. In short, no matter which way to make the sample pieces, must not appear uneven thickness, size bubble, pit lack of material, the surrounding convexity and concave phenomenon. Especially for the sample pieces pressed by mold, when the material is mixed or stirred, it should be repeated several times on the equipment to fully ensure that the material can be mixed evenly. This way the pressed sample pieces of material to ensure uniformity, stable results in the combustion test, and better repeatability of data.   Usually, the sample pieces to be tested should be selected of the same thickness for testing and comparison.
