“ is what 别人家 PVC foaming sheet/plate also light also tough, 我 却 cracking, 起霜, soft 塌塌?
明明照 formulation 做, 结果却差 十万八千里……
its 实, 90% 厂家都踩 this 3 ‘想当然’ 坑!
今天一篇说透, help you lower cost, 直接抄 as 业! ”

?误区1: “ additives add 猛, 效果肯定稳? ”

❌错误操 as :

• ·  outer lubricant （ PE wax ）像不 need 钱一样狂 add → sheet/plate surface 泛白起霜, 一摸一手 powder!
• ·  foaming agent 拼命堆 amount → 泡孔炸 formed “蜂窝煤”, density 反而飙 rise, weight 直逼实木 sheet/plate!

✅ positive 确姿势:

• 精准配 ratio:

  ·  lubricant use “复配 system ”（如 hard acid 钙+ ester type ）, amount control in 1%以 inner, lubricated also 不析出.

• 科技助 force:

  · 搭配宏福 nano processing additives , small separation uniform dispersion, foaming more fine 腻, agent use amount drop 30%!

?误区2: “ temperature degree high, 塑化越 fast good? ”

❌错误操 as :

• ·  extrusion machine temperature degree 直接飙 to 200℃ → PVC separation understanding 冒黑烟, sheet/plate 材变脆一掰就断!
• ·  cooling water to most low temperature → sheet/plate internal “冻伤”, bending deformation 像麻花!

✅ positive 确姿势:

• separation temperature:

• ·  add material 段: 140-160℃（ temperature melt 化）
• · 熔 melt 段: 170-180℃（黄金塑化区）
• · 口模段: 180-190℃（ stability molding ）

• 缓 cold process:

    ·  water temperature control in 20-25℃, 像“ temperature water 敷脸”一样 let sheet/plate slow slow type, internal stress!
  
  

?误区3: “ filler 越便宜, 赚 越 more? ”

❌错误操 as :

• · 贪便宜 use poor carbon acid 钙 → sheet/plate surface 坑坑洼洼, strong/high degree low to can 当“ one-time property use product ”!
• ·  recycling material 随便掺 → 沉淀, 起霜, full, 客户跑 light light!

✅ positive 确姿势:

• filler for:

• ·  use coupling agent modified carbon acid 钙, uniform 无杂质, cost high 10%, strong/high degree 翻倍!
  

• recycling material use:

  ·  ratio/proportion control in 30%以 inner, 搭配钙 zinc stabilizer , environmental protection also stability!
