6000m3/h, combustion-supporting 500-600 DEG C of air temperature, oxygen-enriched ratio 0.023-0.024, Jiao's material compare 0.185-0.2.
C, melted melt is flowed on centrifuge roller head by siphon port, by centrifugal force into silk, binding agent along
The heart wind that blows off is sprayed onto on fiber, binding agent discharge rate 0.8-1%, one roller linear velocity 95-105m/s of centrifuge；Two roller linear velocity 110-
120m/s, blow off wind wind speed 90-95m/s；Three roller linear velocity 120-130m/s, blow off wind wind speed 110-120m/s；Four-roller linear speed
125-130m/s is spent, blow off wind wind speed 110-120m/s.
D, the fiber that centrifugation produces is piled into cotton into " z " repeatedly under pendulum effect, is sent into by web plate collection cotton into a felt
Curing oven cures, and three sections are heating and curing as area drying, the drying of 2nd area and the drying of 3rd area, and the temperature of area drying is 140-
160 DEG C, the temperature of the 2nd areas drying is 170-190 DEG C, and the temperature of the 3rd areas drying is 220-240 DEG C, curing oven hydrofuge
Degree 40%.
E, rock wool blanket is suppressed through pressure roller, cuts fixed specification is made, and the unit weight of rock wool blanket is 70-90kg/m3, and thickness is
25-100mm。
With above-mentioned pro-skin type fire prevention rock wool blanket, the binding agent by forming as follows：
The present invention is by rock wool fibers modification and improves curing process, and obtained rock wool blanket fiber is finer and closely woven, neat, face
Color uniformly, slag ball it is few, it is soft, do not prick the hand, can directly contact skin, nonirritant and allergic reaction, have concurrently fire prevention and
Flexibility, greatly facilitates construction operability, is widely used in steel building fireproof heat-insulation system, strengthens market competition
Power, reduces production cost.
