Embodiment 1
[0045] The natural rubber latex with a concentration of 40%, an ammonia content of 0.05% and a temperature of 80°C is pumped into the pressure device. The pressure of the natural rubber latex is 1Mpa, and the switch valve is opened to allow the natural latex to flow into the air through a jet port of 0.1 mm. The gasification chamber (the pressure of the gasification chamber is atmospheric pressure) is gasified to form natural rubber wet particles of 0.03-0.08mm.
[0046] The wet particles are collected and dried in a drying equipment at a temperature of 120°C for 70 minutes to obtain natural rubber raw rubber.
[0047] The physical and chemical properties of natural rubber raw rubber are shown in Table 1.
[0048] The physical and chemical properties of table 1 natural rubber
[0049]
[0050] It can be seen from Table 1 that the physical and chemical properties of the prepared natural rubber raw rubber meet the index requirements of the national standard GB / T8081-2008SCR5...
Embodiment 2
[0052] Concentration is 10%, ammonia content is 0.15% and the natural rubber latex that temperature is 70 ℃, in the pressure device with pump input, the pressure of natural rubber latex is 2Mpa, then the switch valve of continuous pressure device and injection port is opened, makes natural rubber latex It flows into the gasification chamber through a jet port of 0.15 mm (the vacuum degree of the gasification chamber is 0.08Mpa). Gasified to form natural rubber wet particles of 0.05-0.1 mm.
[0053] The wet particles are collected and dried in a drying equipment at a temperature of 120°C for 70 minutes to obtain natural rubber raw rubber.
[0054] The physical and chemical properties of natural rubber raw rubber are shown in Table 2.
