Power.The test method for the mechanical property for measuring backing is described herein.By be purchased from 3M companies be suitable for it is dry and wet operation
The processed paper wood of 100gsm and 135gsm latex is used as reference.
The measurement of tensile strength
It is executed after stablizing 24 hours in climate controlling and the laboratory humidity (CTH) and the dry of backing is adjusted.It will carry on the back
After the duration that lining impregnates 60 minutes in water, it is performed for measuring the test of tensile strength of backing.
Table 1 shows the comparison tensile strength of the backing and two kinds of processed paper woods of latex of the present invention.In dry and profit
Under the conditions of wet, in the case where UTM instron machine devices are pulled with 305mm/min, tensile strength is tested in machine and transverse direction.
Long 225mm is used to test tensile strength with the backing that width is 24mm.It is strong come the stretching for testing backing according to ASTM standard D3759
Degree.Test condition is：
1. gauge length -100mm.
2. crosshead speed -300mm/min.
The measurement carried out in the longitudinal direction is designated as (MD) data.Longitudinal direction means that the backing kept in the vertical direction is enterprising
Row measures.Laterally (CD) data are derived from horizontal direction or horizontal direction.
Table 1
2 data of table are shown by the way that nonwoven polypropylene fabric laminate and the processed paper wood of latex are impregnated 60 points in water
Clock, nonwoven polypropylene fabric laminate and the tensile strength of the processed paper wood of latex decline under wet conditions.

Maximum load is in higher range.Under wet conditions, the tensile strength of the processed paper wood of latex and non-woven backing is
It is comparable.Compared with the paper wood backing being remarkably decreased for showing tensile strength under wet conditions, non-woven backing is shown
Tensile strength under wetting conditions decline it is very low/or almost without decline.Non-woven backing is at least by the shadow of wetting conditions
It rings.
Table 3 is shown under dry and wetting conditions, in the case where UTM instron machine devices are pulled with 305mm/min,
Tensile elongation percentage on vertical and horizontal.Compared with the processed paper wood of latex, the tensile elongation of supatex fabric
Higher.Better tensile elongation in non-woven backing makes validity period of the abrasive product in damp sand mill or dry sand mill application
Between anti-puncture.
