How Does Natural Rubber Come From? ——Cut Rubber Articles

First of all, the rubber farmers use the hand to go to the glue line to solidify the rubber on the bark, and then use the rubber knife to cut the bark along the trace of the last tapping, the depth is about 2 to 3 cm, latex The liquid is stored in the milk duct inside the bark. If it is too deep, it will hurt the structure inside the trunk. If it is too shallow, the glue will not flow smoothly and harvest. After cutting, the milky white glue will continuously flow out by the swell of the milk duct itself and the surrounding cells, and finally the rubber tree itself flows out along the lower iron pipe of the tapping line. At this time, the rubber farmer has already filled the glue. The container is placed under the tin tube and only the glue is to be collected. This is the whole process of rubber farmers in tapping.


Why do you want to cut rubber at night?

The root cause is the large amount of harvest. The rubber tree must be exposed to sufficient sunlight during the day to carry out photosynthesis, so that various elements in the tube can be chemically reacted to form a rubber liquid composed of rubber hydrocarbons as the main component. The optimum temperature for tapping is 19 °C to 25 ° C,


The amount of latex and dry glue flowing out at this temperature will be relatively high, and the places where the rubber is grown, such as Xishuangbanna, Thailand, Indonesia, etc., can basically reach this temperature from 4 o'clock in the morning to early morning, so if the temperature is too high, exceed 27 ° C. The water evaporates quickly, the latex solidifies quickly, the glue discharge time is short, and the yield is low. The temperature is too low, it is not necessarily good. When the temperature is below 18 degrees Celsius, the latex flow rate will be slower, and the rubber tree will cause dead skin and other diseases. Therefore, it is most suitable to choose from 4 am to 7 am. There is also a hint here that it is generally rainy, the temperature is too cold or windy and other unexpected weather, that is, the tapping operation is stopped.
