Building sealant standard extruder manufacturer direct sales

Product Introduction

1、 Product Overview:

Building sealant standard extruder manufacturer direct salesOne of the testing instruments for determining the extrusion performance of building sealing materials, it uses compressed air to extrude a specified volume of sealing material from standard instruments under specified conditions. For a single group of sealing materials, the extrusion performance is reported by the volume of sealing material extruded per unit time, and for multiple groups of sealing materials, the applicability period is reported by drawing.

2、 Execution standards:

Building sealant standard extruder manufacturer direct salesFully comply with the requirements for extruders in Part 3 of GB/T13477.3-2017 "Test Methods for Building Sealing Materials": Methods for Determining the Extrusion and Shelf Life of Sealing Materials Using Standard Instruments, and strictly follow the ISO requirements for extruder materials based on GB/T13477.3-2017 to meet the requirements of IS09048 standard. The extruder volume is divided into 250ml and 400ml, and the nozzle extrusion hole diameter is divided into 2mm, 4mm, 6mm, and 10mm.

3、 Technical parameters of extruder for building sealing materials:

The volumes of the extruders are 400ml each

The diameters of the extruder holes are 2mm, 4mm, 6mm, and 10mm, respectively.
