plastics processing products dispersion 出令人不愉 fast odor, is this issues meet/satisfy need, plastics resin production processing long 期以 都 in force decrease/reduce this odor dispersion and other grade. solution this issues type methods has: use low odor substitute/replace product substitute/replace that difficult additives, decrease/reduce plastics in mono amount, in plastics in add gas 体吸附 agent and add antimicrobial agent anti generate that due to fine and true function has difficult odor, also has in recycling plastics process in can through solvent agent and gas decrease/reduce odor. plastics in very more combined material tool has difficult odor, amine, 苯酚, alcohol, oxidation material, 苯, aldehyde, ketone, also has increase agent and flame retardant. plastics processing process in use to solvent agent 也会释放出 very strong/high chemical odor. 本文就 can decrease/reduce plastics odor measures 进行 一 brief summary. 1, additives polyurethane ester foam production process in use to catalytic agent amine 常常会 belt/tape very strong/high odor, meanwhile also in automotive inner upper 结雾. solution this issues method is to this amine type substitute/replace material. measures is use more 羟基化 combined material, more 羟基化 combined material not only is polyurethane ester separation formed separation, but also 也同样 tool has catalytic active property. more 羟基化 combined material can 取代一 semi amine catalytic agent, this to product dispersion odor low more. in PVC extrusion or calendering process in use type stabilizer 也经常 by low odor zinc type stabilizer substitute/replace. heat stabilized agent acid 锡也因 its low odor and low features commonly used in use PVC products in. material 提取油如芥 acid and acid need ratio material 提取油 made amine type lubricant （ used for polyolefin and styrene type food packaging materials ） odor small very more. 2, using/adopting more is pure resin many plastics in, especially is in polyvinyl chloride (PVC), styrene, poly acid ester and acrylic ester and other plastics in, micro amount mono generate difficult odor. using/adopting mono 体残留 amount very less resin can remove that odor. if using/adopting 本身即无 odor resin has very good 效果. 例如, DuPont company made types new and other grade shrink aldehyde copolymer, this type of resin in injection processing process in odor non micro amount. 3, add 入吸附 agent in polymer in if filling a small amount of 沸石（一 types aluminum silicon acid salt agent ）, can to remove material odor function. tool has a large amount of crystallization 空洞, this can that tool has odor gas small separation 子. separation 子吸附 agent already formed used for polyolefin extrusion pipe/tube, injection and extrusion blow molding container, packaging materials, extrusion molding outer packaging materials and use polymer. separation 子吸附 powder can as is agent add plastics in remove water 汽, this water 汽也会 has plastics products generate odor. 4, using/adopting antimicrobial agent in plastics in add antimicrobial agent not only can decrease/reduce its dispersion odor, also can products surface aging, color and 变脆. most commonly used antimicrobial agent has 10,10- oxygen di 吩恶砒（OBPA）, oxygen 羟基二苯 ether （Triclosan）, 异噻唑啉 ketone （OIT）, 羟基吡啶硫 ketone （Pyrithione）. has and has machine metal combined material has used as antimicrobial agent. antimicrobial agent multiple applications 5, use understanding methods also has types remove methods is will plastics active property and high surface silicon acid salt and other odor agent in, true 空处理 ring can make this understanding process add fast. use 特殊 清洁 agent solvent liquid plastics pellets can has remove odor. generally this agent is has surface active property agent water property or alkali property solvent liquid. this agent can has remove chlorine ethylene mono 体, styrene, acrylic ester, acrylic mono and saturated and and other. 6, add 入芳香 agent in plastics in add 入芳香 agent can remove difficult odor, is can cover/cap this odor, very more lower this 就足以达 to 目. methods can used for polyethylene (PE), polypropylene (PP) and polyolefin thermoplastic property elastomer, processing methods has injection molding parts molding, extrusion or blow molding. agent time 并不一定 and other molding parts lifespan, its time 决定于 its poly degree, surface ratio, is 否暴露于受 hot or wet ring 境, also has molding parts is 否进行 严密 隔绝空 gas packaging and other factors. agent generally used for toys, day use product, product container, day use electrical appliances and equipment. 7, recycling product waste plastics 往往会 generate difficult odor. large more recycling plastics, 如HDPE, PP, PVC and PET and other, through water solvent liquid remove material. is in plastics internal odor also is 会残留 lower. has machine solvent agent methods has remove generate odor combined material. most new types solvent agent methods also using/adopting ultra- 临界二 oxidation carbon as is solvent agent. this type of technology already application in HDPE and PET upper, it can remove container, agent container and its it waste device parts upper has 味污染 material. oxidation carbon agent benefits in 于不会 belt/tape has machine solvent agent rear issues. odor remove plant/unit is waste plastics pellets extrusion machine 一 组 formed separation, it also can has remove 一 会 generate odor strong/high property combined material. 图1 substitute/replace has machine solvent agent ultra- 临界二 oxidation carbon system remove plastics in property process 8, plastics odor degree odor is 一 因人而异 主观 issues, therefore how to development system degree odor very has difficult degree. 客观确认 odor 第一步 is let 一组人 辨别划 separation 他们 闻 to odor is is 令人愉 fast or is fast. according to small 组 反映, again using/adopting standards device analysis methods gas color 谱, solid light 谱（GS/MS） and other plastics material and other grade. is this relatively 早 仪 device analysis system need expert 进行认 true analysis assessment can 出准确 结论. most new plastics odor testing device is types formed is “ electronics 鼻” plant/unit, it electronics 探头点阵 and 模式识别 technology as. device as sample add hot will 释放出 挥发 material 引导进入探头点阵进行 testing, to 结果以数字模式显示, easy 于同辨别 small 组 结论关联 for 应起. according to specific requirements, material odor can separation is fast, in property, fast, or is strong/high degree and separation poly degree 形式进行 report. 图2 electronics to about/regarding plastics odor separation grade type quality control report in competition plastics market in, property odor make sales large retardant 碍, in property or 者令人愉 fast odor 则会受 to 客户 欢迎. using/adopting odor remove technology can can in short inner increase plastics product cost, is from long 期 说一定会 has very good 回报.
