Plastic should lower 3 steps, because plastic is a step to add meltresin material to cyclinder , Higher stick of resin material ,higher screwback pressure. Screw speed differs depending on decomposing temperatureof resin material ,Higher screw speed ,Higher trim force of resin,higher cyclinder temperature. Some resin material may decomposes so it setscrew speed in mid-speed such as 45-75%, In plastic step setting screwback pressure is very important, Higher screw back pressure ,higherquality of product screw back pressure make resin structure order, Moldingproduct is beautiful and volume stable. But ,it maybe flow if screw

再复杂的熔胶旋转过程最多不会超过三段，因为熔胶本身就是存在于把胶熔进料筒的过程，如果原料粘度大，熔胶压力则大，但速度则应取决于原料的分解温度，熔胶速度越快，原料中的剪切力则会越大，料管温度则越高，局部原料产生分解的可能性则会越大，故一般熔胶会采用中速为宜，如45%-75%，熔胶同时会碰到一个比较重要的环节，那就是背压的使用，产品精度要求越大，背压的使用则更大，背压可使原料分子间结构更紧密，成型出的产品则尺寸更稳定，外观越好。

The Solidification temperature range was defined as 110-200℃ by DSC analysis. More accelerant used can increase the casing samples dynamic performance, but more than enough accelerant can induce a severe solidified reaction that result in a smaller polymeric meshwork and reducing the sample's performance. Normally the Accelerant dosage can be 2 portions; The Epoxy resin CFRP has a obvious better performances than the Vinyl-ester Resin CFRP, i.e. had a Bend Strength of 1516MPa, LSS of 85MPa, also Tg raised to 195~C~ When used the end-carboxyl polyether to reinforce the epoxy resin, the casing sample's SS, BS and Crack Elongation all increased geminately. The CFRP performance also increased a little, that is because the performance of the CFRP mainly contributed by the CF. The reinforced resin improved the interface between the CF and resin that contribute to the little increasing.

通过DSC分析确定了该环氧树脂的固化温度范围为110~200℃，促进剂增加会提高浇注体力学性能，但过多的促进剂会使固化反应剧烈，聚合网络减小，使浇注体性能下降，一般用量为2份左右；以环氧树脂为基体的复合材料性能明显比以乙烯基酯树脂的性能提高，弯曲强度达到1516MPa，层间剪切强度达到85MPa，同时Tg也上升到195℃；用端羧基聚醚增韧环氧树脂后，其浇注体的拉伸强度、弯曲强度及断裂伸长都成倍增加，复合材料的性能也有所提高，但提高幅度不大，因为复合材料的力学性能主要由碳纤维承担，树脂增韧后改善了复合材料的界面性能。

The nickelous chloride both may use in to galvanize, and is prepares the galvanization chemical thionamic acid nickel the important raw material, lead is affects the electronickelling quality a important attribute, in the present industry 331 ion exchange resin deleading effect still could not arrive in the electronickelling the lead content standard, used pocket weak basicity resin XSC312 after the screening experiment determination to take from the nickelous chloride solution intermediate ion exchange except the micro lead resin, inspected the material fluid pH value, the contact duration in the ionic exchange column to the ionic exchange adsorption lead influence, has determined the resin adsorption capacity and inspected the resin analysis performance.
