It is an important material for vulcanization accelerator nobs of rubber , and madicineabob , sulfaguanidine , also for making solvent and assistant of corrosion , inhibitor , surfactant , brightener , polish , emulsifier , homogeneous foaming agent of polyurethane foam plastic , treatment agent of boiler water , alkyl morpholine , dye , resin , wax ; in addition , having wide use in textile and paint 是制造橡膠硫化促進劑nobs和醫藥病毒靈的重要原料。還用于腐蝕抑制劑表面活性劑增亮劑拋光劑增白劑乳化劑聚胺脂泡沫塑料的均勻發泡劑鍋爐水處理劑染料樹脂蠟等的溶劑和助劑的制造,此外還廣泛用于紡織油漆等工業

1 background : at present , a large amount of disposable foaming plastic dining tools mainly concentrated in major cities , major traffic lines , and major tourist sites , gradually forming worsening white pollution , which has become a big public harm to our social environment 1項目背景:目前在社會上大量使用的一次性發泡塑料餐具正在我國城市和主要交通沿線旅游景點形成日益嚴重的“白色污染“ ,成為危害我國社會環境的一大公害。

The product may be installed over a wide variety of substrates including foam plastic insulation board , exterior gypsum sheathing , oriented strand board ( osb ) , exterior plywood , asphalt impersonated sheathing and almost any other code approved exterior sheathing 這種產品可以安裝于各種各樣墊層上面,包括發泡塑膠隔熱板,外置石膏罩,牽線板,耐風化膠合板,仿瀝青罩和幾乎所有其他經編碼核準的外置罩。

Recent progress in the research on the modification , processing technologies and machinery of microcellular foamed plastics / wood fiber composites at home and abroad , including pe / wood fiber , pvc / wood fiber , pp / wood fiber and ps / wood fiber , is introduced 摘要針對pe木纖維、 pvc木纖維、 pp木纖維、 ps木纖維四種微發泡木塑復合材料體系,介紹了國內外在性能改進及工藝設備方面取得的一些進展。

Starch dining tools : it is mainly made from potatos d . non - foaming plastic dining tools are mainly made from polypropylene , which is added with photo degradation agent and biological degradation agent . 3 cooperation intentiona D .光降解生物降解非發泡塑料類餐飲具,主要以聚丙烯為原料,通過在原料中加入光降解劑和生物降解劑等達到降解效果。

Shanghai kangyuan chemical plastic co . , ltd . is a corporation of joint venture by investing of shanghai cailu foam plastic factory and hong kong dayuan garment co . , ltd . together , and was established in may . 1993 上海康元化工塑料有限公司由上海蔡路泡沫塑料廠和香港大元時裝公司共同投資的合資企業,與一九九三年五月正式成立投產。

Now we study on the interface motion forms of bubbles of foaming plastics based on sas software , putting forward new study thought to optimize and adjust every condition to control the quality of cellular plastic 利用sas軟件研究氣體進入聚合物熔體時界面的運動狀態,提出新的研究思路優化和調節各參數來控制發泡塑料制品的質量。

The mechanics properties of two type of the lwts mixed with different foamed plastic beads are researched by the uniaxial compression test , the isotropic compression test and the triaxial compression test 本文對添加不同種類泡沫塑料顆粒的輕質混合土試樣進行了無側限抗壓強度試驗、等向壓縮試驗及三軸剪切試驗。

The use of various - sized wood particles could produce a type of foamed plastic composite boards possessing different and beautiful patterns with a wood grain feeling , but with no reinforcing characteristics 8發泡聚氯乙烯聚合物加入不同大小之木粒片可以產出一種帶有美麗花樣之木理感觸,但無補強效果。

The present situation and the trend of the development of this field are analyzed , the coming application and the market prospect of the microcellular foamed plastics / wood fiber were presented also 分析了目前該領域的現狀及今后的發展方向,并展望了微發泡木塑復合材料未來的應用領域及市場前景。

The tensile mechanical properties of pur foam plastics as well as its strain rate effect and temperature effect were investigated by means of tensile experiments 摘要對高密度泡沫塑料進行了拉伸實驗,研究了材料的拉伸力學性能,并考慮了應變率效應和溫度效應。

The experimental results show that the strain rate effect of pur foam plastics is not obvious , but its temperature effect is quite obvious under tensile loading 實驗結果表明:高密度硬質聚氨酯泡沫塑料在拉伸加載下應變率效應不太明顯,但溫度效應卻十分明顯。
