The strength loss after heat treatment refers to the strength loss after a certain time of treatment at a certain temperature(white alumina), expressed as the percentage of strength reduction. It is expressed by the time required for a certain volume of air to pass through the gap between the surface of the sample and the glass under a certain pressure under a certain vacuum degree(brown aluminium oxide manufacturer), in seconds; otherwise, the better.

The tensile strength of the base paper can be expressed in three forms(black corundum). The bursting strength of the base paper is a reflection of its strength. The strength is good, and the bursting strength is large. Tear refers to the force required to tear the pre cut paper to a certain length, expressed in grams, measured by the paper tear tester(brown fused alumina for grinding). It is an important mechanical property index reflecting the strength and brittleness of paper.


Tensile strength refers to the maximum tension that the paper can bear (kg). Absorptivity refers to the ability of base paper to absorb water, organic solution or other liquids(pink corundum). Obviously, the wetting strength will be lower than the strength of the original sample. Strength generally refers to tensile strength, elongation, folding resistance and bursting resistance(brown aluminum oxide blast media). Smoothness it indicates the smoothness of the paper surface.


Absorptive weight refers to the weight of paper which is increased by immersion in water, organic solution or other liquid for a certain time, expressed as the percentage of weight increase(silicon carbide price). The air permeability is the amount of air passing through the base paper per minute under a certain area and a certain vacuum, expressed in ml / min(white aluminum oxide 220 grit), or the time required to pass through 100 ml of air, expressed in seconds / 100 ml.


There are three ways of expression: capillary absorption speed(green carborundum), refers to the speed of water, organic solution or other liquid rising along the paper page perpendicular to the liquid level, and the result is either the height of liquid rising in a certain time, or the time required for liquid rising in a certain height(white aluminum oxide 120 grit). Surface absorption speed: refers to the time when the paper surface absorbs a drop of water, organic solution or other liquid.


The higher the absorption speed or weight, the worse the ability(brown fused alumina). Water resistance refers to the time when the liquid passes through the base paper. Drop a drop of water on one side of the base paper, and measure the time when the water passes through the base paper to the other side(brown aluminum oxide 70 grit). The air permeability is mainly determined by the density temperature of the base paper, which reflects the moisture resistance of the base paper.


Scalability refers to the relative change of the size of the base paper after being immersed in water at a certain temperature or immersed in water and air dried(brown aluminum oxide), expressed as the percentage of the increase or decrease of the size to the size of the original sample. The scalability also reflects the water resistance of the base paper(white fused aluminum oxide 60 grit). Obviously, the absorptivity reflects the ability of base paper to resist water, organic solution or other liquids.


Wetting strength refers to the wet strength of paper after immersion in water at a certain temperature for a certain period of time(brown aluminium oxide), expressed as the actual strength after wetting, or as the percentage of the strength of the original sample before wetting. Strength generally refers to tensile strength and bursting strength(silicon carbide companies). The more the strength is reduced, the worse the water resistance of the base paper is.
