Castor jargon and reference knowledge - raw materials
We all know that castor is a finished product, which means it is up by something processing with now we see the shape of the raw materials of castor is some what things? Here we mainly, says some of the terminology and castor material reference knowledge, facilitate everybody can more comprehensive grasp some knowledge of the castor material. We usually see a lot of raw materials of castor, such as PU, PP, TPR and rubber raw materials and different we can also according to customer requirements in mixed with different materials, such as to eliminate the electrostatic effect, we can add anti-static materials, so that we can achieve our final a result. Castor material terms: 1, the tensile strength: the wheel from the required force when the cross section is broken. In pounds divided by the number of samples for the unit cross-sectional area ( Square inch) 2, bonding strength: 6 inch/min speed glue the tire from the wheel core of stripping force needed for above, divided by the straight line width tires for the unit with the pound. 3, hardness: used for measurement of rubber and other tire and wheel core material hardness, with shaw represented 'A' or 'D'. 4, compression strength, compression test, in the process of sample on the maximum compressive stress, mpa to bill for the unit. 5, working temperature: measurement under the rated load to the working temperature range. 6, bibulous rate, test sample weight increases with the weight of the sample after a particular order test and the initial weight percentage said. 7, elongation: under the action of tension, the sample fracture line when the distance between the increase and the ratio of the initial range, expressed as a percentage. 8, the impact strength: data receiving free falling weight imposed by the onslaught of performance. Inch/pound, ft/LBS or test temperature stamping work. 9, under the weight of the deformation resistance: a long period of time under heavy wheels flattens the site gets bigger, the test sample must be under static load, and then at the end of the compression time stated on the discharge load, the height of the wheel with location become table after compared with the original high percentage. Castor raw materials in the market now a lot of, can't completely, but the above mentioned terms and reference knowledge can be universal, we can start from this drop, mastering the castor every knowledge; Can use at the same time to live and work in, I believe you will find more correlation, so as to enrich your knowledge of castor material.
