Sample fixation and data collection equipment, and sag resistance performance testing equipment and method

Abstract

The invention discloses sample fixation and data collection equipment. The sample fixation and data collection equipment comprises a testing equipment frame, sample fixing strips and a dividing ruler,wherein the testing equipment frame is used for installing the sample fixing strips and the dividing ruler; four bar elongated slots are formed in two ends of two symmetrical sides of the testing equipment frame along the symmetrical sides; the sample fixing strips are fixed inside the bar elongated slots, and can move along the bar elongated slots to change the lengths of testing samples; the white steel dividing ruler is fixed in front of the testing equipment frame from top to bottom. Moreover, the invention provides sag resistance performance testing equipment comprising the sample fixation and data collection equipment. Moreover, the invention further provides a sag resistance performance testing method. The problem that a conventional plastic pipe resin is complex in sag performancetesting, expensive in equipment and not intuitional in property characterization is solved, and the equipment and method for testing plastic pipe sag resistance performance which is simple in operation, cheap in equipment, various in sample specifications, intuitional and accurate in testing data and high in stability are provided.

Description

technical field [0001] The invention relates to the field of synthetic resins, in particular to sample fixation and data collection equipment, equipment and methods for testing anti-sag performance. Background technique [0002] Plastic pipes are high-tech composite chemical building materials, and chemical building materials are the fourth largest category of new building materials emerging in the contemporary era after steel, wood, and cement. From different plastic pipes using chemical materials, they can be divided into rigid polyvinyl chloride (UPVC) pipes, chlorinated polyvinyl chloride (CPVC) pipes, polyethylene (PE) pipes, cross-linked polyethylene (PE-X) pipes, three Type polypropylene (PP-R) pipe, polybutylene (PB) pipe, engineering plastic (ABS) pipe, glass fiber reinforced plastic (RPM) pipe, aluminum-plastic composite (PAP) pipe, steel-plastic composite (SP) pipe, etc. Compared with traditional metal pipes, plastic pipes have the characteristics of light weight...
