Application of Improved BCM-100H Propylene Polymerization Catalyst in Horizone Device and Development of High-performance Products
When the original BCM-100H catalyst produces high MFR(Melt flow rate)products,the polymer fine powder is more,which is not conducive to the operation of the device.In this paper,the industrial application of the improved BCM-100H catalyst in Horizon is reviewed and compared with the original catalyst and imported catalyst.Three high MFR,high rigidity and high impact copolymerization products K8740H,KH39M and KH75M were developed on this device for the first time using this catalyst.The results show that the activity,sensitivity to hydrogen regulation and copolymerization ability of BCM-100H catalyst remain unchanged after modification.The fine powder≤0.15 mm in product is reduced by about 80%,and the isotactic index(absolute value)of polymer is increased by 0.5%,which is better than that of imported catalyst.The flexural modulus and impact strength at room temperature of K8740H are 1.36 GPa and 8.51 kJ/m2 respectively,which are better than imported similar products.The flexural modulus and impact strength of KH39M and KH75M are 1.57 GPa,6.00 kJ/m2 and 1.59 GPa,5.84 kJ/m2 respectively,which are better than domestic similar products.The selection and optimization of additives can increase the flexural modulus of products by 5%～10%.The flexural modulus and impact strength of the products reached 1.72 GPa and 5.72 kJ/m2 respectively,exceeding the level of similar imported brands.
