         automotive inner material classification

        1. plastics

         according to resin separation structure and thermal properties different, plastics separation is thermoplastic property plastics and hot solid property plastics. automotive inner commonly used plastics large more is thermoplastic property plastics, main/primary 包括PP, PE, PVC, PET, ABS and other.

         automotive table/sheet sheet/plate more using/adopting PVC and ABS 材质, again 注入一 PU foam reinforcement elastic can force;车门 inner sheet/plate more using/adopting ABS or modified PP material injection molding formed 形.

        2. fiber

         textile fiber tool has long degree, fine degree, elastic property, strong/high force and other good physical properties, also tool has relatively good chemical stability property.

         textile fiber in automotive inner in main/primary used for automotive base/seat 椅, inner 壁, table/sheet 皮, safety belt/tape, 隔音垫, and other, remove tool 备一定 product function property outer, versus for/regarding other material, textile fiber in automotive 隔音, thermal insulation, drop 噪方面 has advantages.

        3. leather

         leather in automotive in main/primary used for automotive base/seat surface, surface and other, high 档车 仪 table/sheet sheet/plate outer surface, direction 盘, inner and other, 也会以 leather cover/cap, in certain types degree upper, leather use amount is 车辆档次 and 豪华程 degree 象征.

        4.橡胶

        橡胶 also can by separation formed combined formed and 天然橡胶 this large type. automotive 轮胎, and other.

         automotive inner material features testing

        燃烧 safety testing

        1.极限 oxygen index (LOI) testing

         simple 说, oxygen index (LOI) 指 就 is in conditions lower, in oxygen nitrogen mixed combined gas ring in, automotive inner material has 焰燃烧时 most low oxygen concentrated degree, generally using/adopting oxygen gas separation value for its add table/sheet 示. for/regarding automotive inner material versus for property 判断而言, oxygen index (LOI) is its in important evaluation methods through use methods can has 效判断材 material difficult easy degree. currently, already 经颁布 《 plastics property can experiment/testing methods oxygen index (LOI) method 》 for oxygen index (LOI) testing provide made degree 保障.

        2. water 平燃烧 testing

         in automotive inner material features testing in, water 平燃烧 testing is its in types most basic testing methods. stage/phase methods already 经演变 formed automotive inner product di 方都必 must 进行 一项 automotive inner material property features testing, made 定 《 plastics property can experiment/testing methods water method and method 》 is its provide made degree 保障. from essence upper 说, methods testing principle main/primary is: need testing sample water add in U形架 upper, rear in 燃烧箱当 in, through use 35~38MJ/m3 天然 gas 火源, adjustment 38mm high degree 火焰点燃 Sample 自由端15s之 rear, 观察火焰 can can will testing sample 点燃, and in 燃烧之 rear sample need more can and other. usually 说, its requirements by Sample product water 平燃烧 speed rate must need small 于100mm/min, and, requirements sample 燃烧 火焰 can in to testing front 熄灭.

        3.铺 织 material property can testing

         generally lower, in 进行铺 织 material property can testing 时, use is 铺 织 material property can experiment/testing 仪. this type of testing methods used for automotive inner in various fiber separation and structure property can testing in.

        4. 垂直燃烧 testing

         in made 定 《 textile product property can experiment/testing method 》 in, for/regarding has flame retardant requirements material flame retardant property can 测定 规定. generally 说, methods main/primary combined automotive cationic sheet/plate (V窗帘 and other various 悬挂式材 material testing. remove outer, its also for automotive tube/pipe, and other related electrical appliances flame retardant property can non 常严格 requirements. through use 垂直燃烧 testing methods, for and time 进行测 amount analysis, according to sample can can and material can can will 脱脂棉点燃 and other, for sample and other grade 进行评定.

        熔 melt property can testing

         generally 说, based on 《 machine 动车辆特定 type type internal structure using/adopting material features 》 in 规定, requirements 我们必 must need for inner 顶部材 material 进行熔 melt property can testing. in 进行实际 实验 process in, main/primary is 选取4 37 experiment/testing sample,然 rear will Sample using/adopting water 平放置 methods,放 in hot lower 面,然 rear again use upper 置辐射 hot 源, to Sample 30kW/m2 hot 辐射,并 will testing time maintain in 5min, for Sample phenomenon 进行记录. combined standards sample requirements its in 出现熔滴之 rear,不会 will lower 面 棉絮点燃.

        3.烟 density property testing

         generally 说,我们 commonly used density testing main/primary below/following types:第一 types is plastics density testing 仪,第二 types is building materials density testing 仪. due to automotive inner material different, therefore using/adopting density testing device and methods 也就不 use. for/regarding automotive inner material 说, its 包含 缓冲材 material large separation is PP and PU foaming material, therefore 说,就针 for/regarding this material 而言,我们 more more selection plastics density testing methods. for automotive inner sheet/plate and inner sheet/plate and other inner material 而言,则 more more is using/adopting building materials density testing 仪. in addition, due to material in process in generate property material will for 人体造 formed non heavy 危害,针 for issues,我们 using/adopting main/primary is material method and chemical analysis methods 进行毒 property evaluation and analysis.
