YY易游平台
The materials YY易游平台 additives used in silica mixing in the tire industry, YY易游平台 the associated reaction by-products, have increased the requirements for the mixer chamber YY易游平台 rotors to be anti-corrosive. At the same time, as the filler (silica) content of these new compounds increases, so too does the need to have an anti-abrasive surfacing material.
The mixing chamber must have anti-corrosion YY易游平台 anti-abrasion characteristics to satisfy these conflicting requirements.
KA#T1 has been developed to have high YY易游平台 balanced anti-wear YY易游平台 anti-corrosion performance for the mixing chamber for silica masterbatch mixing. It also has a good bonding strength with chrome plating, which provides stable tip clearance before becoming worn. KA#T1 YY易游平台 Cr plating provides the optimum conditions for longer stable mixing (productivity YY易游平台 quality) compared with hard surfacing alone. KOBELCO has delivered this solution on approximately 80 mixers since 2011.
KA#93 has high anti-corrosion performance YY易游平台 is applied to Kobelco’s rotors. It has an improvement in anticorrosion over the conventional KA#104 while also having improved anti-abrasion performance over the traditional hard facing material used on rotors.
Again, KA#93 has good bonding strength with Cr plating, providing extended life. In addition, KOBELCO also offers a range of other materials that can meet application processing needs YY易游平台 address specific wear YY易游平台/or corrosion concerns.
Maintaining compound temperature at a fixed level is applied in silica mixing to improve the coupling agent reaction. This is achieved by controlling the rotor speed through a feedback loop from the batch thermocouple. Kobelco has developed a new high responsive thermocouple. Compared to the stYY易游平台ard one, it is possible to measure temperatures closer to actual mixing temperature, YY易游平台 its lifetime has improved by a special hardfacing KA#53.
New tread compounds are designed to improve the balance grip, energy efficiency YY易游平台 anti-wear characteristics of the tire. Materials to improve rubber-to-metal adhesion are used to reduce the tire weight, YY易游平台 these additives can cause problems by increasing the amount of compound that sticks internally on the drop door. The ‘spade door top’ has been developed specifically for these adhesive compounds to avoid material hang-up while improving compound flow around the door.
KOBELCO BBMC (BB-Mixer Monitor & Controller) has various functions to support mixing operations such as manual operation, data logging, automatic operation, IoT function YY易游平台 maintenance function.
These functions achieve not only controlling the quality of various kinds of mixing efficiently, but also provide records of mixer status YY易游平台 information for the maintenance.
