Description

(5) СПОСОБ ОПРЕДЕЛЕНИЯ ПРОЧНОСТИ СЦЕПЛЕНИЯ ПОЛИМЕРНОГО СОЕДИНЕНИЯ(5) METHOD FOR DETERMINING THE STRENGTH OF POLYMER CONNECTION COUPLING

Изобретение относитс  к испытательной технике и может быть исполь зовано при определении прочности сцеплени  полимерных соединений. Известен способ определени  прочности сцеплени  покрыти  с подложкой заключающийс  в том, что в подложке выполн ют надрез, подложку с покрытием закрепл ют в захватах разрывной машины и прикладывают раст гивающую нагрузку до разрушени , по величине которой суд т о прочности сцеплени  покрыти  с подлох(кой П 1. Наиболее близким к изобретению по технической сущности и достигаемому результату  вл етс  способ определени  прочности сцеплени  полимерного соединени , выполненного из подложки и нанесенного на нее покрыти , заклю чающийс  в том, что используют стерж ни с разными диаметрами, последовательно изгибают испытуемое соединени вокруг стержней, начина  от стержн  с большим диаметром, до разрушени  соединени , а при оценке прочности учитывают диаметр стержн , при котором произошло разрушение соединени  2. Общим недостатком известных способов  вл етс  низка  точность определени  прочности сцеплени  соединени , так как покрытие при испытании находитс  в сложном напр женном состо нии . Цель изобретени  - повышение точности определени . Дл  достижени  указанной цели согласно способу определени  прочности сцеплени  полимерного соединени , выполненного из подложки и нанесенного на нее покрыти , заключающемус  в том что используют стержни с разными диаметрами , последовательно изгибают испытуемое соединение вокруг стержней, начина  от стержн  с большим диаметром до разрушени  соединени , а приThe invention relates to a testing technique and can be used in determining the adhesion strength of polymeric compounds. A known method for determining the adhesion strength of a coating to a substrate is that a notch is made in the substrate, the coated substrate is fixed in the grips of the tensile machine and a tensile load is applied before destruction, judging by the magnitude of the adhesion of the coating to the underrun ( 1. The closest to the invention in its technical essence and the achieved result is a method for determining the adhesion strength of a polymeric compound made of a substrate and a coating applied to it, consisting of ohms that use rods with different diameters, successively bend test joints around rods, starting from a rod with a larger diameter, before breaking the joint, and when evaluating strength, take into account the diameter of the rod at which joint failure occurred 2. A common drawback of known methods is low the accuracy of determining the adhesion strength of the joint, since the coating, when tested, is in a complex stress state. The purpose of the invention is to improve the accuracy of determination. To achieve this goal, according to the method for determining the adhesion strength of a polymeric compound made of a substrate and a coating applied to it, consisting in the use of rods with different diameters, the test compound is subsequently bent around the rods, starting from a rod with a larger diameter before breaking the joint, and
