Shanghai Daoqin Plastics Co., Ltd.

         plastics products in processing process in dispersion 出令人不愉 fast odor, is this issues, large long 期以 都 in force decrease/reduce this odor. in addition, very more 朋友会 in new material in add ratio/proportion recycling material, pelletizing production 时味道 more heavy, this is production in 普遍存 in difficult 题, below/following is provide types solutions:

         pelletizing rear has causes

        材 material comparison 杂

        材 material more processing degradation

        材 material in small separation material separation understanding

         has water has material very strong/high accelerated degradation function

         due to plastics products in add additives or recycling material, make plastics products in belt/tape ethylene, hydrogen, oxidation 硫, amine, 氨臭味 or its it 异味. separation odor in products 存放一段 time rear by 释放; has 时则潜伏 in plastics products in, processing this has gas by 释放出, formed plastics 异味. solution 异味 典 type methods has 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. can through solvent agent and gas decrease/reduce odor.

         plastics 异味处理

        1, positive use 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.

         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, recycled material 处理

         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.

        3, 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.

        4, 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.

        5, 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.

        6, 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.

        7, 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, extrusion or blow molding.

        芳香 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.
