產(chǎn)品介紹

一、產(chǎn)品特點(diǎn)

1.本產(chǎn)品為低分子量聚乙烯蠟,流動(dòng)性較好,因此具有良好的加工性能。

2.作為PVC專(zhuān)用潤(rùn)滑劑,其獨(dú)特的熔程控制,使其既具有良好的后期外潤(rùn)滑效果,又具有良好的前期內(nèi)潤(rùn)滑效果,在擠出機(jī)不同的加工區(qū)段起到內(nèi)外潤(rùn)滑平衡的作用。

3.在加工前期作為內(nèi)潤(rùn)滑時(shí),能在一定程度 上降低塑料熔體的粘度,有利于物料在螺桿的剪切推動(dòng)下順利前行;在加工后期作為外潤(rùn)滑時(shí),能有效的降低熔體控制加工電流,在一定程度上延遲塑化,避免因剪切力過(guò)大造成的物料分解。

4.在物料和口模金屬填充母粒專(zhuān)用聚乙烯蠟內(nèi)壁之間形成一層均勻的潤(rùn)滑界面,使物料能勻速的擠出,從而提高制品表面的光亮度,同時(shí)也能提高擠出量,增加產(chǎn)能。

5.本產(chǎn)品可用于各類(lèi)PVC制品的生產(chǎn),包括管材、 管件、型材、電纜料、木塑、扣板等。

One,product characteristics

1. This product is low molecular weight polyethylene good flowability, so it has good processability

2. PVC as a special lubricant,its unique welding process control, which has not only at the late stage of good lubrication effect,but also has good lubrication eft in the early,inside and outside lubricating balance function in the processing section of different extruder.

3. As in the processing of pre lubrication, , can reduce the viscosity of the melt plastic in a certain extent, is conducive to the smooth material in front of the screw shear driven; in the later period of processing as a lubricant, can effectively reduce the melt pressure,control current, to a certain extent delay plasticizing, avoid excessive shear stress the resulting material decomposition.

4. Between the material and the die metal wall to form a uniform layer of lubrication interface, so that the material can be uniform extrusion, thereby improving the products surface brightness, but also can improve the output, increase production capacity.

5. This product can be used in the production of various PVC products, including pipes,fittings, profiles, cable materials, wood plastic, gusset plate and so on.
