        我国黑 slip 石资源丰富, in slip 石资源 day 益紧缺 时代, research discussion slip features and in modified plastics in application separation necessary. 初步试 use table/sheet in requirements degree field/area, slip increase rigid function significantly, application outlook/prospects good.

        1 我国黑 slip 石 资源情况, features and in modified plastics in application necessary property

         slip 石原矿 has 白, 绿, powder 红, and and other color separation, color main/primary 取决于 and slip 石共生 its it formed types type. has amount has machine 质时, slip 石原矿 is color or black.

         slip is important industrial raw materials, is world upper slip 石资源 large 国, is and export large 国. slip its appearance good, slip pure degree high, sheet/slice structure 完善, by development to application. 辽宁海城, 山东栖霞, 广西龙胜 and other slip is 名声显赫, 远销欧, 美, Japan and other 国. due to long high strength, degree 开采, excellent and other slip 石 资源 already versus for 紧缺, price rise. 辽宁海城 excellent and other slip 石原矿(white slip 石矿) price already to 千元/吨 above, abrasion formed powder already 达几千元/吨.

黑 slip 石

         slip powder is important modified plastics important raw materials 之一. slip powder sheet/slice 状(层状) structure make its filling plastics rigid property significantly improve/increase, flexural strength and modulus and other significantly high filling material, 随之而 is filling modified plastics heat deflection temperature (HDT) obvious improve/increase, from is requirements high rigidity plastics material and products (如 automotive 保险杠, machine housing/shell and other industrial parts and ring rigid degree requirements high plastics pipe/tube) processing manufacturing belt/tape can property, but also remove price more high outer, also has property ratio more its it material material can substitute/replace.

         color good, pure degree high slip price day rise most large effect/influence is formed modified plastics Raw Materials cost increase, for/regarding color appearance requirements high plastics products this type of 态势无 can 奈何, for/regarding requirements color or for its requirements high plastics products, automotive 保险杠, di 壁波纹 tube/pipe and other plastics products, need structure good, increase rigid significantly, its it color slip is can to combined has application. this not only is make plastics processing industry to property ratio low modified raw materials, but also is for 原 不 by heavy 视甚至 is by has color slip 石资源 most good utilizing, for 社会做出 巨 large 贡献!

        2 黑 slip basic features

        我国 main/primary slip 石储区 and slip oxidation material 计 矿 material formed table/sheet 1.

         table/sheet 1 我国 main/primary slip 石储区 and slip material formed (以 oxidation material 计)(%)

        我国黑 slip already 探明 储 amount is 6~8 100 million 吨, its main/primary formed material is slip 石, 石英, understanding 石, 海泡石 and other, 各 黑 slip 石 矿 material formed although has significantly 差异, from material formed 看, it and slip versus 似, therefore 显现出 black, main/primary is has 3~5% carbon, this in high temperature 煅烧时 can by 烧失.

        传统 use types slip 石 产 and material formed (以 oxidation material 计)见 table/sheet 2.

         table/sheet 2 四 types slip and material formed (以 oxidation material 计)

        黑 slip high temperature can is degree high 矿石. 江西广丰 黑 slip 石煅烧 temperature degree 1250℃ left right, in 1200℃时原矿瞬间变白, its density is 2.7g/cm3 left right, in strong/high light lower in surface upper can to many 发亮 晶体, main/primary is CaO 缘故. abrasion rear degree can 达93% above.

        3 黑 slip application current situation and in plastics in application discussion

         currently slip 石原矿 main/primary used as generally 陶瓷 坯体, rear can used for high 档陶瓷如抛 light 砖, material. as is filling material can used for paint coating material, 造纸, textile and other field/area. in plastics in application due to 传统观念以 white slip is standards, 经煅烧 rear to relatively high degree 才考虑 use, 而煅烧 cost high 昂, process complex, its rear abrasion formed slip powder property can and 功效未 can add system research, therefore in modified plastics in application to has and 投入.

         in China modified plastics 专业委员会 安排 and lower, 以山东玉塑 tube/pipe company is 主进行 黑 slip in increase rigid requirements relatively 迫切而 property ratio can high HDPE di 壁波纹 in application experiment/testing, obtain research formed 果.

        3.1 slip powder types type and features (见 table/sheet 3)

         table/sheet 3 different types type slip powder features

        3.2 experiment/testing process/workflow

        3.2.1 slip powder material and pipe/tube made as, property can testing

         for types slip powder use surface treatment agent types type use amount same, masterbatch additives use amount has different, resin amount same. material made as and tube/pipe extrusion same, process as conditions basic same.

        3.2.2 slip powder filling HDPE材 material property can Sample strip/profile made as and property can testing

        3.1 experiment/testing 结果(见 table/sheet 4, table/sheet 5)

         table/sheet 4 slip powder filling HDPE di 壁波纹 tube/pipe property can

        四 types slip powder material made as di 壁波纹 tube/pipe pipe/tube material is full new resin HDPE 2480, its and material use amount ratio is 2: 1.

         table/sheet 5 slip powder filling HDPE材 material material force property can

        3.2 讨论

        (1)H01 slip powder is 经典意义 upper most good slip powder, slip content high (以SiO2计), sheet/slice structure significantly, therefore for di 壁波纹 tube/pipe increase rigid function most is significantly, this is in material in. tube/pipe use this type of slip powder pipe/tube heavy relatively high, 意味 壁 thick, has ring rigid degree improve/increase, relatively 之G06 and G08 pipe/tube ring rigid degree high 出18%, increase thick is can can.

        (2)H06 is type slip 石, H08 is color deep by slip 石矿弃置不 use 尾矿, 不经煅烧, will its abrasion formed powder, use its production di 壁波纹 pipe/tube ring rigid degree to 8kN/m2, has obvious increase rigid 效果.

        (3) use has color slip abrasion formed powder (H06, H08) production di 壁波纹 tube/pipe, relatively use H01 slip powder 时, its processing flow property more good.

        (4) from different types type material filling HDPE材 material material force property can upper 看, 经典意义 upper most good slip powder (H01) filling HDPE材 material force property can most good, tensile strength, flexural modulus, impact strong/high degree is most high, Vicat softening temperature comparison high, this 恰恰说明 slip powder sheet/slice structure for HDPE rigid property improve/increase is has 利. meanwhile 也应看 to its it types powder filling HDPE材 material property can versus for H01 is 差一, 但总体 upper property can 也不错, especially is slip 石(H06) filling HDPE材 material its flexural modulus to and H01同样 效果, if for filling material appearance color requirements high, slip increase rigid also is significantly. and table/sheet 4 data comparison, filling material force property can testing performance modified is 一致.

        4 展望

        初步 research experiment/testing table/sheet slip 石不经煅烧 is drying rear 直接研 abrasion formed powder, tool has significantly increase rigid function, processing flow property good. due to its price versus for low 廉, is in 不苛求 color plastics material and products use in tool has good property can price ratio, its application outlook/prospects good. if its carbon in (3~5%) can in plastics resistant aging has 贡献(has 待证实)就 more has use 武之!
