3) no-bake furan resin
自硬呋喃树脂
1.
In our country, no-bake furan resin is one of the main molding materials in the production of cast-iron products, low nitrogen furan resin is also abroad used in the production of cast-Steel products, at present, it is one of the widest applications in foundry binders at home.
自硬呋喃树脂是我国铸造行业中铸铁件所使用的主要造型(芯)材料，同时对于低氮的呋喃树脂来说也广泛用于铸钢件的造型材料中，呋喃树脂是我国在造型材料中应用最多的树脂砂之一，但呋喃树脂在生产及制备砂型方面还存在着一些问题，主要表现在：树脂粘结剂含氮量偏高，砂型固化速度慢，生产效率不高，树脂粘结剂成本较高，合成树脂中游离甲醛含量偏高，致使在混砂、造型和浇注过程中散发有害气体，污染环境，损害工人身体健康。
4) Self-solidified furan resin without nitrogen
无氮自硬呋喃树脂
5) furan resin sand
呋喃树脂砂
1.
when producing ductile castings with furan resin sand, the C and S resulted from decomposition of resin and catalyst penetrated into molten iron and caused large quantities of fine flake and dot-shaped supercooling graphites in some areas of the casting which are appearing as dark color defects on the machined surfaces.
采用呋喃树脂砂型铸造球铁件时,由于树脂和硬化剂分解产生的C、S渗入铁液使铸件表层局部区域形成大量密集的细片状和点状过冷石墨,这些区域加工表面上呈灰暗色。
2.
The reason causing nodularization degeneration in surface layer of furan resin sand nodular iron castings was analyzed.
对呋喃树脂砂球墨铸铁件表层球化衰退原因进行了分析。
3.
