Degradation principle of biodegradable materials
The degradation principle of biodegradable materials mainly involves the comprehensive effect of microorganisms and their secretions under enzymatic or chemical decomposition. Specifically, the degradation process typically includes the following key steps:
-
Microbial secretion of hydrolytic enzymes: Under suitable conditions, bacteria, fungi, algae and other microorganisms in the soil will secrete hydrolytic enzymes outside the body, which can bind to the surface of the material.
-
Hydrolysis: Through the catalysis of hydrolytic enzymes, the high molecular weight chains on the surface of the material are cleaved, resulting in the formation of small molecular weight compounds.. This process is the core link of degradation, which gradually transforms polymer materials that were originally difficult to decompose into low molecular weight substances
-
Microbial Metabolism: Low molecular weight compounds generated by degradation are subsequently ingested by microorganisms, and through a series of metabolic processes, these compounds are ultimately converted into microbial biomass or energy for microbial activity, and discharged into the environment in the form of water and carbon dioxide.
500um engineering tire vulcanization label
Excellent high temperature stability, able to withstand the heat and pressure of tires during high temperature and sulfur treatment (up to 210 ℃)
Excellent durability and wear resistance
Excellent chemical corrosion resistance: Strong waterproof, acid resistant, salt resistant, alkali resistant, most petroleum oil stains, oils and low-fat solvents, adhesives can penetrate into the concave surface and firmly bond to the softening agent that penetrates the tire surface. When the car is in operation, the barcode will not fall off on its own, and manual peeling will not damage the rubber on the tire surface
Excellent barcode/heat transfer printing effect, combined with Xiyan VR-30 carbon ribbon, ensures 100% accurate reading and scanning on the high-speed conveyor line before and after vulcanization
Excellent adhesion: When the tire is removed from the mold, it has strong flexibility to withstand tire deformation

250um tire vulcanization label
Excellent high-temperature stability, capable of enduring the heat and pressure (up to 210℃) during tire usage and vulcanization with sulfur.
Outstanding durability and wear resistance.
Excellent chemical resistance: Strong waterproofing, resistant to acids, salts, alkalis, most petroleum stains, oils, and low-fat solvents. The adhesive can penetrate into concave surfaces, firmly bonding with the softener that penetrates out of the tire surface. When the vehicle is in operation, the barcode will not fall off spontaneously, and forced manual peeling will not damage the rubber on the tire surface.
Excellent barcode/thermal transfer printing effect, combined with XiYan VR-30 ribbon, ensuring 100% accurate scanning and reading on high-speed conveyors before and after vulcanization.
Excellent conformability: When the tire is removed from the mold, the strong flexibility can withstand tire deformation.
