         must versus for/regarding pure material in production in generate 节约 说, mono 组份 额 outer cost.

        一, masterbatch production methods

         large more masterbatch main/primary also is powder material made formed. mono types color 需 颜 material through dispersion additives, wax and other and powder plastics raw materials separation and, rear in di screw extrusion machine formed dispersion, uniform distribution in plastics raw materials in.

        注: in 实验室 di screw extrusion machine in dispersion and production upper 实际状况并不一定一致, therefore in production 时, must in rigid 开始时就检查 color value, 并进行 necessary positive.

        二, use mono production masterbatch

         mono types color masterbatch production through 两步完 formed, 第一步 is production mono 组份(先 production high concentrated degree color masterbatch), rear again production masterbatch. will material most high concentrated degree dispersion in plastics raw materials in as is mono methods. currently, most high concentrated degree high 达40-50% has machine material and most high concentrated degree 达75% 无 machine material can through extrusion methods dispersion to plastics in obtain good dispersion 效果.

        注: dispersion quality good is plastics in material pellets non fine 腻, can obtain can can good color can force, 另一方面, 不允许出现 ultra- 5 micron material block, 以免形 formed color 斑.

        实验室 in mono color adjustment and 取样以 and material production is mono screw extrusion machine formed. is material already dispersion good, different mono 组份 需 in mono screw extrusion machine in melt and mixed and. due to 实验室 and production in dispersion quality same, 实验室 in obtain raw materials color value can degree in production in can to ensure.

        三, extrusion production cost factors

         extrusion production cost (equipment cost, can 源, force, agent and waste material and other)都取决于 use machine and dimensions and processing amount large small.

        1. di screw extrusion machine pelletizing

         has machine material in di screw extrusion machine in dispersion to plastics in 开支不斐. 平行同 toward di screw extrusion machine long ratio low 于40, is ensure 适当 输入, extrusion screw has 数 部 parts combined function, use this type of extrusion machine generally production has machine material use amount versus for relatively small masterbatch.

        无 machine material density high, more easy dispersion, therefore use di screw extrusion machine production output/production volume high many. therefore, mono machine material dispersion cost ratio has machine material cost low. most large material concentrated degree and large machine large amount production, can make mono mono material dispersion cost drop most low.

        2. mono screw extrusion machine pelletizing

         due to mono screw machine 不一定 need dispersion, can can need melt and mixed and, therefore in structure upper ratio di screw extrusion machine simple many. not only more 愿意购买, but also it also has lower advantages: easy 清洁, production loss consumption low, easy as, raw materials dry 净, 无尘, mixed and fast.

        3. according to mono amount selection extrusion machine type type

         small mono (<1t)

         processing 25 至1000公斤 small amount masterbatch 时, generally using/adopting relatively small machine. mono screw extrusion machine tool has upper has 点, use small extrusion machine (如 screw is 45 mm) processing most high 至500公斤 批 amount advantages most obvious. versus for/regarding powder material, mono production formed outer cost to 补偿. due to can non fast more color, masterbatch production therefore obtain 理想 灵 active property (fast speed reaction mono 位).

         relatively large mono (>3t)

         if masterbatch output/production volume ultra- 3吨, use mono screw and di screw extrusion machine extrusion production cost versus 当, 此时, most methods must according to formulation 定. if machine material (如: TiO2) and has machine material mixed material need in di screw extrusion machine in dispersion, can will has machine material separation mono 组份 形式 add 进, this need will machine material distribution 进 就 can). due to has machine material need again dispersion, machine material can relatively high speed degree dispersion.
