Reclaimed Rubber Making Line :
rubber powder,coaltar,black rosin ---devulcanizer(after devulcanizing)----rubber mixing mill ----rubber prefiner-----rubber refiner ----reclaimed rubber sheet
Description of line:
1.When you get rubber powder, first to desulfurization
powder & mesh 100
solid coal tar pitch 9
bipentene 2.5
Rosin 3.5
Activator 420:0.8
desulfurization process conditions of vapor pressure 0.98MPA, time 4hours
2. Then to open mixing mill.Milling process After the desulfurization of rubber has lower
plasticity, in order to improve its plastic milling must be conducted.Milling has the following two ways.
(1). BoTong mastication will continuously mixing mill with 2-3 in units, roller roller spacing as 1 mm,
2roller temperature control under 70.When milling rubber, through the first machine by the scraper from
roll after falling on the conveyor belt, sent to the second machine BoTong, in turn, can achieve
kneading.This continuous production, low labor intensity, high production efficiency.
(2). Single, double automatic milling in a mixing machine equipped with automatic feeding device, roller
spacing for 1 to 2 mm, roller temperature control under 70.Rubber roller after Jane by dropping it on a
feeding conveyor belt, by turning device will return to rubber mixing rubber to repeated milling
machine.The time usually at about 10 min.
(3)After the above two methods, milling rubber plasticity is 0.3to 0.4
3. Then to refining machine
Refining purpose has two: one is the refiner speed ratio is large, use the shear stress to make rubber
molecules further broken;2 it is refining mill roller is drum-shaped, under the small roller spacing can crush rubber material is not fully in the desulfurization of hard particles, or will the hard particles on both ends of the roller line clearance.Is reclaimed rubber refining machine dedicated equipment, appearance and mixing mill, just roll Jane among larger diameter, rotational speed is faster.From general roll control in 0.2 0.4 mm,roll temperature under 90, roll temperature too high or the film too thin are easy to make the rubber performance degradation, especially temperature had a greater influence on the quality of reclaimed rubber
products.In order to get uniform quality of film, should strictly control the temperature, shall not exceed 90,and remained stable.The refining, rubber refining mill general for two times, the number of times can take two refining machine as a unit, each with a single;Or a refining machine through twice, should be
determined depending on the specific equipment conditions.The rubber after refining, appearance quality to achieve smooth and exquisite, no obvious particles and impurities.Plasticity to reach more than 0.35
(rubber shoes at 0.4 or above).
