How many black masterbatch plastic production to add?
Release time：2016/9/23
Adding filler masterbatch plastic in the processing production is a very common thing, this is also the industry's consistent practice. Whether out of cost control, or for improving plastic products performance, add filler masterbatch is a win-win. But filling masterbatch is also a double-edged sword, with black masterbatch, add in black masterbatch in plastic products, must have good control of the quantity, if added, will increase the cost of our plastic products, and can't make plastic products the best color effect, quantity is little, prevent ageing agent and carbon black of black masterbatch can't fully mix, so make sure the quantity of the good control ofblack masterbatch.
So how many black masterbatch is added in the plastic production is appropriate? This is not a accurate answer, HYMANTOPBON suggested dosage is 1% 3%, the concrete depends on product requirements.
Reality in processing and manufacturing plastic products in addition to add black masterbatch, anti aging in to add fertilizer, also use the aging proof agent and carbon black with a blend of black masterbatch, make the anti aging effect more significant effect, this also reduces the dosage of black mother, saves the cost of production. The biggest reason is that using a length of time in the outdoor is different, also have certain requirements for the life of the product, these two premises also determines the black masterbatch dosage must be moderate, also cannot be used too much.
If we add the quantity of too little, can cause carbon black, in the case of products produced in discontinuous in the parting of the combination, plastic molecular connections will be very vulnerable. If not close, ultraviolet irradiation, carbon black can absorb a large number of products of heat, accelerate the oxidation of the products, in this case, the use of black masterbatch counterproductive, become the impurity in the products.
Must be in the case of parting in less than 280 nm, can avoid ultraviolet light, so that the use of black masterbatch is safe. Want to build a high quality plastic, besides have need of good raw materials, has a mature matching method and the scientific operation is necessary.
