• used for manufacturing medical material parts, 如牙科植入 material, and 膝关节, and 心脏起搏 device outer housing/shell.

2. is what oxidation titanium in plastics application in by use?

2.1. improve/increase heat resistant property

二 oxidation titanium (TiO2) usually by used as plastics industrial in white color agent, improve/increase plastics products heat resistant property. titanium powder add to plastics in 时, it 充当一 types 晶核生 formed agent, this it has 助于促 make plastics internal formed structure. this structure reinforcement plastics strong/high degree and resistant property. in high temperature lower, this structure more add stability, can more good resistant deformation and 熔化.

plastics heat resistant property can through multiple methods through use titanium powder improvement:

• improve/increase plastics melting point: through improve/increase melting point, plastics can in more high temperature degree lower resistant 受熔化, make its more combined in high temperature application in use.

• improvement plastics heat stabilized property: improvement heat stabilized property has plastics more good resistant high temperature lower deformation and separation understanding, make its more solid and can 靠.

• improvement plastics outer stability property: titanium powder is types has absorption outer 线 材 material, can plastics 免受紫 outer 线辐射 loss 害, improve/increase its lifespan and can property.

2.2. improve/increase resistant light property

remove improve/increase heat resistant property outer, oxidation titanium also improvement plastics resistant light property, make its more can 抵御褪 color and color, plastics in cationic light or other light lower 时, more 佳.

二 oxidation titanium improvement plastics resistant light property mechanism is through its dispersion and absorption light can force. add to plastics in 时, oxidation titanium pellets various direction dispersion light 线, decrease/reduce light plastics amount. this decrease/reduce plastics absorption light can amount, from decrease optical separation understanding speed degree. oxidation titanium pellets light dispersion and has 效 充当屏障, plastics light 线接触 危害.

in addition, oxidation titanium tool has relatively high rate, this it ratio other material more can bending and decrease slow light 线. this type of features make oxidation titanium can uniform dispersion light 线, make appearance more add uniform, decrease/reduce non-uniform hot or color can can property.

2.3. reinforcement plastics weather resistance

plastics very easy to gas factors effect/influence, cationic light, wet degree, temperature degree 异常变化, this 会导致 plastics 变质并丧失 its mechanical properties. oxidation titanium is types has additives, can decrease light this effect/influence improve/increase plastics weather resistance.

titanium powder reinforcement plastics weather resistance main/primary methods is through its absorption outer 线辐射（UV） can force. TiO2 is types high absorption outer 线 材 material, add to plastics in 时, it can absorption cationic light outer 线辐射, anti its polymer 链. through absorption UV辐射, TiO2 retardant electronics -空穴 for formed, decrease optical separation understanding speed degree, long plastics product use lifespan.

titanium powder also can as is retardant 隔层, retardant wet gas and other ring factors 侵入. add to plastics in 时, TiO2 pellets formed types retardant 隔层, anti wet gas and other ring factors 渗入. this has decrease light gas factors effect/influence, cracks and warpage, meanwhile plastics 免受天 gas factors 侵害.

in addition, titanium powder also can used as plastics filling material. as is filling material, it improvement plastics mechanical properties, hardness, tough property and impact resistant property. this make plastics more can 抵御天 gas and other ring factors effect/influence, reinforcement its weather resistance.

2.4. plastics color

二 oxidation titanium is types high 效 颜 material, add to plastics in 时, can make product 呈现出 white, transparent tool has high rate. therefore, this type of material in plastics industrial in used for production color masterbatch, used for plastics white color.

二 oxidation titanium through types is dispersion process achieve white material 效应. light 线进入含 has TiO2 pellets plastics product 时, light and pellets versus function 并以各 direction dispersion 射. this type of dispersion 射效应 in can light short in most strong/high 烈, 包括蓝 light and light. is TiO2 pellets white, is it 们反射 can light has color.

二 oxidation titanium as is white material is due to its high rate, light 线穿 介质时 bending degree degree amount. TiO2 折射 rate is 2.55, high large more used for plastics in other material. this TiO2 pellets more has dispersion light 线, generate more white.

2.5. improvement plastics electrical property can

resistant property, hardness, elastic property and impact resistant property, make material more add solid, resistant deformation.

二 oxidation titanium as is reinforcement agent function is improve/increase plastics mechanical properties main/primary factors 之一. this is is ultra- fine pellets oxidation titanium can force can and plastics polymer versus combined, formed more solid and hard structure. 随 二 oxidation titanium pellets surface increase, pellets and polymer between 接触点 increase more, has improve/increase material mechanical properties.

remove mechanical properties, oxidation titanium also can improvement plastics electrical property can. this is is oxidation titanium is types has insulation material, can decrease/reduce plastics products conductive property. in certain lower, oxidation titanium also can electrical or can material, electrical can.

will oxidation titanium used as plastics additives also has reinforcement material dimensional stability. this in need dimensions and 公差 情况 lower non important, in manufacturing machine parts or mold 时. oxidation titanium can used for anti plastics in cooling and solid process in shrinkage, from generate more add uniform and can forecast most product.

总之, use oxidation titanium in plastics in tool has more important benefits. this type of 天然矿 material can improve/increase plastics products property can and quality. through toward plastics in add oxidation titanium, manufacturing can production more solid, more resistant use, more 美观, more can resistant cationic light, hot amount and other ring factors product.
