The reason is sticky resin sand exploded about 500 ° C, the resin sand removal, mold gap increases and loss of feeling, sticky liquid iron sand to form a preventive measure) increased core compactness 2) thick at the original sand can be used as a special zirconium sand and cold welding iron ore, etc. 3) brush fire-resistant coating and appropriate to reduce the pouring temperature 4) type suitable furan resin. Liquid material adjustment resin sand regeneration manufacturers, the liquid material is added in an amount determined by how much liquid feed pump motor speed, the liquid feed pump motor speed is the input data from the drive or the governor decided. Therefore, the data on the drive or the governor to realize how much liquid material adjustment amount, the specific operation: ①, first of all the ways to manipulate electricity Kongpan positions were open on manual pump cured resin pump sand resin regeneration sets equipment, reflow and a pipeline full of liquid fluid material may not have bubbles phenomenon. ②, to manipulate the way to convert the cabinet to measure (time) position, the desired measurement of liquid materials such as resin agent valve switch in the ON position resin sand regeneration, take a good container to be automatic after a liquid outlet to pick Under the Start button, the liquid material out of 10 seconds to turn off. Weighing meets the user's process requirements resin sand reclamation plant, 1000kg / 36 × process requirements should value% resin. Same method to obtain accurate by adjusting the amount of resin drive or governor, adjust with resin curing agent, the amount of size should be 1000kg / 36 × process required value% × process requirements resin hardener value% resin sand recycling equipment Hebei resin sand regeneration, provided by Qingdao Qingdao Heng Heng Machinery Co.
