WDW-10/20/50
Microcomputer Controlled Thermal Insulating Materials Testing Machine
1.Main function & application:
  This series machine adopts portal structure and is mainly applicable to test tension, compression, bending and other mechanical property indexes for metallic, nonmetallic, composite materials. Its precise auto control and data acquisition system realizes full digitalization adjustment to data acquisition and control procedure. For tensile test, it can test max. bearing tension, tensile strength, extension strain, elogation and other technical indexes, which all can be calculated after test through main controller according to test parameters set before test and meantime display test results. All the parameters can be both inquired and printed.
  
  The manufacturing and verification standards: GB/T16491-2008 Electronic Universal Testing Machine; JJG139-1999 Metrological Verification Regulation for Tensile, Compression and Universal Testing Machine; and national standards as:  ASTM, ISO and other industrial standards and also users can set test methods and calculate methods themselves.
1.It has remote control box through which can adjust crossbeam moving, operating flexibly, switching randomly.
2.After test, it can automatically return to the original position, intelligent, efficient, quick.
3.It has limit position protection function, overcurrent protection function, reliable, safe.
4.It has strong test database and can save, inquire and recall test data.
5.It can realize constant speed control to speed, stress, deformation, strain, stroke, load, extension, displacement, low-cycle control and self-programming control.
6.It can realize switch among many test curves: stress-strain, load-deformation, load-displacement, load-time, deformation-time, displacement-time, load-strain. It has functions of test curve partial enlargement, superposition and comparasion.
  This series machine is applicable to metal, cementing compound, tubes, sectional bars, aerospace, petrochemical, waterproof rolls, wire and cable, textile, fiber, rubber, ceramics, food, mechical packaging, geotextile, film, wood, paper and other industries and quality supervision department, and it also can be used in college for teaching demonstration.
  Application range of thermal insulating materials: JG149-2003, JG158-2004, GB/T5386.2-2001, GB/T7689.5-2001, GB8813-1998, GB/T17671-1999, GB/T9641, JG/T24-2000, JC/T547-2005, GB/T16777-1997( users should provide the compression grips themselves), JG/T157-2004, GB/T8813-88 Test Method of Compression Property for Outer Wall Heat Insulating Material; JGJ144 Technical Criterion for Outer Wall Heat Insulating Engineering.
Note: Additional accessories should be added.
