1) Identification of duoduoduolong and polyester
Polyester will melt in case of strong alkali, so it’s not easy to get more
When polyester is roasted with fire, it will emit smoke, and the exhaust pipe will emit black smoke
Ribbon manufacturer
2) Identification of polyester and PP
Generally, polyester ribbon is woven first and then dyed, so the tone of yarn after splitting will be white due to uneven coloring, while PP ribbon is extracted by sealing rubber and liquid silicone rubber according to high temperature, and the extracted yarn is already colored, so it is not easy to be white- Ribbon manufacturer
Polyester has smooth handle and glossy surface
The ductility of polyester is better than that of PP
Polyester will sink into water (relative density is 1.05 > water density), PP is not easy (0.95)
Polyester will melt in case of strong alkali, PP is not easy to melt
Polyester will melt in sulfuric acid, but PP ribbon is not easy to melt
3) Identification of PP and duozhilong
There are many dragons
Many dragons are softer
Duoduolong has stronger tensile strength than PP
PP Ribbon will float on the river when it is put into the water, but it’s not easy to have many dragons
4) Identification of acrylic board and cotton
The acrylic board will turn into a mass of black nodules after ignition, and the cotton board will turn into embers / powder after ignition
Acrylic board ribbon is made of two kinds of materials: nylon and cotton. Therefore, the tensile strength of acrylic board is higher than that of cotton
5) Identification of SP line and acrylic plate
The tensile strength of SP wire exceeds that of acrylic plate
SP line will turn into a ball shape when ignited, and acrylic board will turn into a black ball when ignited
The surface of SP line is bright and clean, with color, and the surface of acrylic plate is hairy
PS: tensile strength is relatively strong, SP line is the strongest, acrylic board is the second, cotton is the worst.
