Natural rubber is an elastic material collected from natural plants. There are no less than 2,000 kinds of plants containing rubber in nature, such as tall trees, shrubs, herbs and climbing vines. Our traditional rubber trees and rubber grasses. , dandelion, etc. contain rubber components
Collection of natural rubber: The latex exists in the milk tube of the rubber tree bark. Every morning, the bark is cut at a certain angle on the trunk at a certain inclination angle to break the milk tube, and the milky white latex will flow into the cup containing the latex under the cut. The rubber tapping system is to cut every other day when the secant length is 1/3~1/2 of the tree thickness, and it must be cut again every three days throughout the week. In short, it should be based on the principle of not causing damage to the trees and maintaining a high latex yield.
The Distinction Of Rubber Mouse Pads
The natural rubber mouse pad material is the juice extracted from the clover tree in Xishuangbanna, after drying, foaming, laminating, cutting, sublimation, molding, and finally sent to the customer, because the final process needs to be sublimated at a high temperature of 220 degrees , which causes the smell of rubber to dissipate lightly. This kind of taste is a normal source material taste, green and environmental protection will not harm the human body, and the duration of this taste is very short. It is only available in new products, just like when a new book first arrived, there is a smell of trees. All substances have their original characteristics. This is a normal rubber smell. If you don't like it, pls release the product open for a day or two and it's gone.
The source material of reclaimed rubber mouse pad is also a kind of plant extract juice, which is a little worse in quality than clover extract, and it is also environmentally friendly. Some other ingredients are added during the foaming process, resulting in a pungent taste of the source material. In fact, the real reason for this taste is not the source material itself, but the odor of the product of the added ingredients. This odor Whether the mouse pad is harmful to the human body has not been found so far, but after all, it contains other additives, which have a very serious glue smell, and many people cannot adapt to it.
Nature Of Natural Rubber
NR has good cold resistance, but not good heat resistance: It has good elasticity at -50℃. Its long-term service temperature is 90℃, short-term maximum service temperature is 110℃. NR has good elasticity: The elasticity and resilience of NR are second only to BR in general purpose rubber Mechanical properties High mechanical strength, belongs to self-reinforcing rubber: Tensile strength of pure vulcanized rubber: 17 ~ 28MPa Tensile strength of carbon black reinforced vulcanized rubber: 25 ~ 35MPa The comparison of mechanical strength of various rubbers: NR > IR > CR > IIR > NBR > SBR > BR Good resistance to flexion and fatigue: generally more than 200,000 times Good wear resistance: Wear resistance is related to the strength of rubber. Rubber wears well because of its high strength. Good insulation: NR volume resistance 1014~1015 ω •cm (insulator volume resistance 1010~1020 ω •cm) Air tightness Good self-viscosity and mutual viscosity. Chemical medium resistance NR has good resistance to chemicals and general solvents. It is resistant to dilute acid, dilute alkali, concentrated acid, oil and poor water resistance. NR, as a non-polar polymer, is soluble in benzene, gasoline and petroleum oils, but insoluble in polar oils.
