Technique:
First, turn the roll pitch of the open mill to the minimum (zero pitch, add the rubber (10-40 meshes) or 100 parts by weight of the waste rubber leftovers and 2 parts by weight of the rubber Recycling chemical RV2101 to the open mill, mill for 12 mins and mix evenly; then sheet out.
Note: The roll temperature should be below 70ºC.
Using the refining mill has a good effect and high efficiency, and the whole process can be finished in 8 min.
At the same time, we developed the coordination reclaiming of the rubber mechano-chemical reclaiming reactor and the rubber double-screw extruder, which realized the successive production.
We realized recycling the waste rubber at normal temperature and pressure and formed the assembly production line, which is a leap of the rubber reviving technique.
Principle:
When the solid material is added with mechanical energy, its solid-state, crystal structure, etc. change, as a result, the physical and chemical property change is called mechano-chemical. The rubber machinery sheering and shattering process is accompanied by the impact of the mechano-mechanical, when the force works on the waste rubber, the force initiation is produced, and the active particles are generated, at the same time creating force splitting, and generating molecule chain break sheet with big free radicals property When degrading the vulcanized rubber, the free radicals are on the C-C= bond instead of C-S bond, but when there is C-Sn-C bond, 30% C-C bond will be directly destroyed, while 70% is chain broken caused by the shift of the unpaired electron to the sulfur created by breaking the C-C bond. The splitting does not always happen on the weakest bond, but can also happen on the stronger bond, when there is a weaker C-S bond, it can split on the C-C bond. As the atomic energy of the RMCD rubber mechano-chemical chain scission depolymerizing agent and the lone pair electrons of the sulfur atoms among the sulfur organic compound form a coordination bond, making S-S bond and S-C bond weaker, and cutting S-S bond and S-C bond under the mechanical force and in this way, we can reclaim the waste tire rubber powder. As the rubber mechano-chemical chain scission depolymerizing agent RMCD has many chain-break options, the break of the rubber molecule main chain C-C bond is small, so the revived rubber keeps the higher physical property.
Characteristics:
Applied by many domestic manufacturers, it obviously shortened the processing time, increased the break elongation, and reduced the Mooney viscosity of the revived rubber. What is the most important is that the dosage is induced. It needs only 2 parts by weight of RV2101 per 100 parts by weight of waste rubber, which saves the company recycling chemical cost of 200 RMB more than the first generation when recycling one tone waste rubber and realizes energy saving and emission reduction.
The revived rubber can be vulcanized without adding any vulcanizing agent and accelerator, which can save the processing aid valued 500 RMB, (GB/T13460-2008 the standard recipe of the reclaimed rubber is: reclaimed rubber 300g, accelerator NS 2.4g, zinc oxide 7.5g, sulfur 3.5g, stearic acid 1.0g;of which one ton of the reclaimed rubber need to consume the processing aid valued 500 RMB to vulcanize production),so one ton of the waste rubber only needs the reclaiming agent valued 200RMB to revive to the rubber product.
If 20% of the revived rubber is used to substitute the raw compound rubber, the dosage of the accelerator in the raw compound rubber can be reduced by about 20%, which can further save the costs about 100 RMB. RMCD rubber mechanochemical chain scission depolymerizing agent (hereinafter referred to as RV2101) is suitable for applying deep products.
