The traditional hopper, buffer bucket, tee, chute, chute and other equipment are equipped with manganese steel, stainless steel and other lining plates, or directly replaced with stainless steel, which has high cost.
The use of food grade wear-resistant, anti pulling and anti-static lining materials can reduce the cost and improve the quality of prefabricated parts without reducing the use requirements and quality.
2.
The selection of lining material depends on different conveying materials and industries.
The lining material can be natural rubber, special polyurethane, polyether, etc.
The natural rubber lining board is the natural rubber processed according to the food safety requirements after obtaining the natural rubber juice from the rubber tree.
It can be used to process rubber products in contact with food, and can customize all kinds of natural rubber products such as sealing, protection, environmental protection, flame retardant, conductive, insulation, shock absorption and damping for customers; The traditional lining plate has the advantages of fast wear, high noise, difficult parking and maintenance and long time.
Therefore, the lining plate made of manganese steel leads to great overall cost of the equipment.
The inner inlaid wear-resistant natural rubber lining plate can solve the problems of high noise, fast wear, difficult parking and maintenance and long time of traditional manganese steel, stainless steel and other lining plates.
The installation is convenient and simple, and the labor intensity is greatly reduced.
Moreover, the wear-resistant natural rubber lining plate has super wear resistance, impact resistance, tear resistance and long service life.
3 natural rubber is a natural rubber product mainly made of natural rubber, which has passed the relevant national food contact rubber testing standards and reached the food grade.
Natural rubber: it is divided into concentrated latex and solid standard rubber.
Concentrated latex: it is a liquid substance processed by high-speed centrifuge.
It must be kept fresh by adding ammonia in a special barrel, and the dry rubber content is 60%; Solid standard rubber: it is a standard rubber after solidification, machining, drying and packaging.
It is divided into several levels according to the content of impurities.
It has international standards and corresponding standards in various countries.
4 origin of rubber tree: it comes from the western region of malayue in the Amazon basin of Brazil, mainly Brazil, followed by Peru, Colombia, Ecuador, Guyana, Venezuela and Bolivia.
It has been distributed to more than 40 countries and regions in Asia, Africa, Oceania and Latin America.
China: rubber planting areas are mainly distributed in Hainan, Guangdong, Guangxi, Fujian and Yunnan.
In addition, it can also be planted in Taiwan, of which Hainan is the main rubber planting area.
Southeast Asia: tropical areas of more than 30 countries are introduced and cultivated, and Southeast Asian countries are the most widely cultivated and produce the most gum.
Malaysia, Indonesia, Thailand, Sri Lanka and India account for 90% of the world’s rubber planting area and rubber production.
Thailand: the annual output is about 3.3 million tons (the annual output is still rising), accounting for one third of the world.
Indonesia: Indonesia has the largest planting area and the second largest rubber producing country.
Malaysia: it is a country where rubber and palm replace each other.
Malaysia’s standard glue is the best in the world.
Because it adopts standardized production and strictly controls the quality, the price of Malaysia’s standard glue is the most expensive in the standard glue.
5 planting conditions rubber tree is a tropical plant, which likes high temperature, high humidity, calm wind and fertile soil.
It is required that the annual average temperature is 26 ~ 27 ℃, and it can grow and produce rubber normally within the range of 20 ~ 30 ℃.
It is not resistant to cold.
It will be damaged by freezing below 5 ℃.
The annual average precipitation is required to be 1150 ~ 2500 mm, but it is not suitable to plant in low humidity places.
It is suitable for the growth of acid sandy loam with deep soil layer, fertile and humid, and good drainage.
The climate, soil and other natural conditions in Southeast Asia are more suitable for the growth of rubber trees, so rubber trees can be widely planted in Southeast Asia.
