Introduction to samples and fixtures of the insulation system of materials testing machines in and outside

Exterior wall insulation finish coating is compatible with glue powder polystyrene granule insulation system, but its performance is in compliance with relevant national industry standards. The following detailed description is made for JG/158-2004 glue powder polystyrene granule exterior wall insulation system.

Samples: 100x100x70mm 5 pieces (use adhesive to bond the upper and lower surfaces of the sample to the 100x100mm metal plate respectively)

Fixture: Metal plate: 100x100x5mm 10 pieces

Tensile speed: 5mm/min to damage Record tension and damage area

Compressive strength Softening coefficient

Sample: 100x100x100mm 5 compressive test loading rate: 0.5-1.5kN Calculate 5 arithmetic averages

Softening coefficient

Sample: 100x100x100mm 5 compressive test loading rate: 0.5-1.5kN calculate 5 arithmetic averages

tensile strength

According to JGJ144-2004 Technical Specifications for Exterior Wall Exterior Insulation Engineering A.7 Tensile Strength Test Method

Press shear bonding strength

Sample: Cement mortar block 110x110x10mm 10 pieces Use standard slurry paint to apply between two cement mortar blocks, and the two pieces are opposite and staggered by 10mm.

Testing machineFixture: 110mm mortar shear device, upper pressure head 120x20 or Φ150mm 1 set

Test: Compression test speed: 5mm/min Loading to damage Calculate 5 arithmetic averages

Tensile bonding strength of crack-resistant mortar, water-soaked tensile bonding strength

Press JG/T 24-2000 Synthetic resin emulsion sand wall-shaped building coating

Crack-resistant mortar fold ratio

According to GB/T17671-1999 Cement glue sand strength inspection method (ISO method)

Alkali resistant grid cloth, strength of break, strength of alkali resistant, retention of elongation of break

Sample: Width 50mm, length 300mm, radial weft direction, 20 pieces each

Corrugated tension fixture: width 60mm, clamping height 50mm, 1 set/2 pieces

Tensile speed: 100mm/min stretch to break the record tension

Tensile strength Elongation of break

Dumbbell-shaped I-type test piece 120x10x2 6 pieces No treatment stretch test

According to the "GB/T 16777-1997" architectural waterproof coating test method 8.2.2

Fixture: Corrugated tension fixture: Width 60mm Clamping height 50mm 1 set/2 pieces

Test: At a tensile speed of 200mm/min, the load during breaking is recorded, and the distance between the markings of the specimen at this time is measured (L1), accurate to 0.1mm, and 5 test specimens. If the specimen breaks outside the markings, the result is invalid, and spare parts should be used to make up.
