高压发泡机与低压发泡机的区别
高压发泡机低压发泡机
1. 价格昂贵. (US$ 50,000~150,000) 1. 价格低廉.(约US$ 40,000~50,000)
2. 制作精密. 2. 制作简单. (可在中国制造)
3. 混合效率好，泡沫泡孔构造稳定均匀, 绝
缘性能好.
3. 混合效率不好，泡沫不均匀，绝缘性能差.
4. 由120~200bar的混合室压力进行强力混
合
4. 在混合头采用电机强行混合
5. 浇注完成后，混合头内不会遗留残余物料，周围始终干净. 5.因混合头内部空间大, 会遗留残余物料, 为了清除这些物料. 不得不使用氯带甲烷等有害环境的溶剂.
6.因不产生残余物料, 泡沫质量好, 所以会节省原液使用量(约5~10%) 6. 因混合效率不好，残余物料多，所以原液使用量比高压发泡机多5~10 %.
7. 管理和启动方便，周围始终干净. 7. 管理困难, 周围环境不好.
8. 产品质量优秀. 8. 很难制造高品质产品.
9. 因混合效率好，不会发生后期发泡. 9. 因混合效率坏，会产生后期发泡.
10. 没有环境污染. 10. 在欧洲已禁用低压发泡机. (因使用有害物
质，造成环境污染)
11. 耐久性好. 11. 耐久性差.
12. 可以用于自动化生产线. 12. 只能用于手工生产, 不能用于自动化生
The difference between high pressure foam machine and
low pressure foam machine
high pressure foam machine low pressure foam machine
A.expensive (US$ 50,000~150,000) A.inexpensive (about US$ 40,000~50,000)
B. accurate fabrication B. simple fabrication
C．Effective mixing，stable and uniform cell structure of foams,good insulation properties C．Ineffective mixing，unstable cell structure of foams,bad insulation properties
D. strong mixing by 120 ~ 200 bar mixing
chamber pressure
D.forced mixing in hybrid motor
E.After completion of pouring, mixed
residual material won't be left in the head, always around clean. E.Because of the mixing head internal space is
large, the residual materia will be left in , in order to clean these materials，have to use solvent which harmful to environment such as chloride methane
F.No residual material, produce good
quality bubbles and save raw material (about 5~10%) F.More residual material, waste more raw
material ,more than 5~10 %.
G.Easy to operate and maintain ,keep
cleanly
G.More difficial to operate ,maintain and clean
H.Produce high quality production H.Hard to produce high qualilty production
I.No last foaming I.The lsat foaming will waste material
J.No pollution e harmful material,and it’s disable in
Europe
K.Good durability K.Good durability
L.Can be used for automatic production
line.
L.Only can be used for manual production。
