我发现, certain flame retardant and 感冒药 has 99.99% versus 似...
提起胶囊, can can large 家并不陌生, has 伤风感冒流鼻涕, 都会吃一 types 叫做感冒胶囊 东西.
in upper, 药装入胶囊, 既保护 药 material property by bad, 也保护 消化 device and 呼吸道. 掉胶囊 housing/shell can can formed material 流失, material 浪费, reduce. another, has material need in inner solvent understanding absorption, is types 保护, 保护药 material by acid bad.
但 is micro 胶囊化, can can full understanding 人就不 more. that 么, what is micro 胶囊化呢?
micro 胶囊化 technology is use or combined formed polymer material used for coating solid 体, liquid or gas 体以形 formed in 1-1000μm scope/range inner micro 胶囊. micro made can to 20世纪50 year 代, 当时Green and Schleicher through and 阿拉伯树胶 composite/compounding poly made micro 胶囊化染 material, used for manufacturing carbon 复写纸. to currently is 止, micro technology already widely used in made 药, food, 农药, material, paint, product, agent, versus material, textile product and other industry.
micro 胶囊 形状 is more 样, simple 讲, micro usually 由两部 separation formed: and housing/shell. polymer, (明胶, 阿拉伯树胶, 琼脂, 琼脂糖, acid salt, 角叉菜胶, wax, wax, wax, powder, 糊精, low poly 糖, 几丁质 and other), combined formed polymer (polyurethane ester, polyester, polypropylene (PP) acid ester, poly 脲, polyethylene (PE) alcohol, polyamide (PA), ring oxygen resin, polyether, aldehyde resin, poly amine resin and other) and machine material (硫 acid 钙, 石墨, silicon acid salt, aluminum, aluminum 土矿, 玻璃, viscous and other)均 can used as housing/shell.
usually, micro can tool has different 形状, from use type type 看, micro can separation is type, pressure type, hot type and type light micro and other.
micro made methods has very multiple, usually separation is chemical method, material chemical method and material machine method types, table/sheet 1 in Common made methods.
而 flame retardant micro 胶囊化也 is 如此, main/primary using/adopting methods 包括原位 polymerization method, interface polymerization method, poly method, versus separation method and solvent liquid drying method and other, table/sheet 2 is specific made principle.
that 么, is what flame retardant need micro 胶囊化呢?
this is is through micro 胶囊化处理 rear flame retardant usually tool has below/following advantages:
1, reduce certain resistant water property flame retardant water solvent property
当 flame retardant polymer composite/compounding material in high wet degree ring in use 时, its in has certain resistant water property low flame retardant easy solvent understanding or to composite/compounding material surface, composite/compounding material flame retardant property and mechanical properties has reduce. ratio Common APP就 has this 方面 隐患, through APP surface coating upper anti water polyurethane ester resin, large large improves its resistant water property can.
2, increase polymer and flame retardant versus property
certain flame retardant and polymer between property different, from 而导致 flame retardant and polymer between tool has relatively versus property, flame retardant very difficult in in dispersion uniform, polymer composite/compounding material material mechanical properties decline. if use combined polymer as is housing/shell coating flame retardant, can improvement flame retardant versus property. use acid acid fiber 素(CAB) micro 胶囊化APP并 used for flame retardant ethylene - 醋 acid ethylene ester copolymer (EVA). due to CAB and EVA均 tool has 乙酰基, therefore CAB housing/shell can reinforcement micro 胶囊化APP(MCAPP) dispersion property and EVA基质 and MCAPP between versus property.
3, flame retardant appearance and material 理状态
例如, liquid flame retardant can micro 胶囊化 is “ solid 体” flame retardant, make flame retardant easy and polymer blending. in addition, micro 胶囊化也 has anti flame retardant and 挥发.
4, improve/increase flame retardant hot understanding temperature degree
当 flame retardant use tool has more good heat stabilized property housing/shell micro 胶囊化时, flame retardant hot understanding temperature degree will reinforcement, from expand large flame retardant application scope.
5, anti or decrease/reduce has gas 体 释放
micro 胶囊化 rear, flame retardant property odor or has gas in its processing and process in will by or decrease/reduce.
currently in scope/range inner already has multiple micro 胶囊化 flame retardant, micro 胶囊化 hydrogen oxidation 镁(polystyrene (PS) 包覆), micro 胶囊化红磷(三 poly amine - 甲 aldehyde resin 包覆, polystyrene (PS) 包覆), acid hydrogen micro 胶囊化(polyurethane ester 包覆, has adipic acid and poly ethylene glycol ester poly amine aldehyde 包覆), poly acid micro 胶囊化(三 poly amine - 甲 aldehyde resin 包覆, polyurethane ester 包覆, ring oxygen resin 包覆, fiber 素包覆, silicon housing/shell 包覆), acid poly amine micro 胶囊化(nylon 6 包覆), type flame retardant micro 胶囊化(三乙 alcohol amine - 甲 aldehyde resin 包覆, polyurethane ester 包覆, poly amine - 甲 aldehyde resin 包覆, aldehyde resin 包覆笼状 di ring acid ester), has machine flame retardant micro 胶囊化(戊二 aldehyde -PVA resin 包覆DMMP), has machine flame retardant micro 胶囊化(三 poly amine - 甲 aldehyde resin 包覆DBDPO) and other and other.
micro 胶囊化 is flame retardant provide 特殊 核 - housing/shell structure. through this type of structure, micro flame retardant not only tool has more good property can, but also application scope more 广. for/regarding different polymer, can design and made different 核 - housing/shell structure. currently, market upper already 经出现 very more micro 胶囊包覆 flame retardant, micro 胶囊包覆红磷 and micro 胶囊包覆 poly acid 铵, make and poly acid application more add 广泛. need attention/notes is micro flame retardant in processing and process in and mechanism also has 待进一步 research.
