It can typecast wet or dry shape sand, improve the cast quality. in a word, it is a fine quality cast sand adhesives, which has the character of dilatability, cohesiveness, floatability. and gel dispersivity, repeated use
可以澆注濕態和干態型砂，改善鑄件質量，並有良好的復用性，是一種優質的膨脹劑，黏合劑，懸浮性和膠體分散性的鑄造型砂粘結劑。The heat expansion coefficient of casting nylon materials is about 10 times larger than steel, so the internal dia shrinks caused by the expansion. it will influence the connection gap of the abrasive surface
鑄型尼材料的熱膨脹系數約比鋼材大10倍左右，所以軸套在運行時由於摩擦熱所造成的膨脹變形使內徑縮小，影響摩擦面的配合間隙。A special molding material ? expansion plaster used for this process could obtain 3 % expansion after being treated, which is beneficial to compensate dimensional contraction for plaster mold drying and alloy solidification
工藝中所用的特殊造型材料? ?膨脹石膏經處理后可得到3 %的膨脹量，足以抵消鑄型因烘烤產生的尺寸縮小及合金凝固導致的收縮。A thermal expansivity test device consisting of hating unit, attemperating unit, displacement transducer, recorder and so on, was developed to determine the thermal expansivity of new sand, clay - beaded sand, sodium silicate sand, resin bonded sand with the temperature or isothermally
摘要鑄造用砂熱膨脹性測試裝置，由加熱裝置、溫控裝置、移位傳感器、記錄儀等組成，可實現鑄造用原砂（亦可用於粘土型砂、水玻璃型砂、樹脂型砂等）的隨溫和等溫熱膨脹性測試。Both ways derive from the concept of sa and ohen, but they take two opposite routes : the first one is with a space - contracted model that is from macrocosms to microcosms, and the second with a space - expanded model from microcosms to macrocosms
這兩套認知模型均以魂靈為建構基點，但它們對宇宙的鑄模走的是兩條相反相承的路徑，前者由大及小，由宏觀而微觀，走空間壓縮型認知路徑；後者恰恰相反，由小及大，由微觀而宏觀，走空間膨脹型認知路徑。Test method for properties of investment casting ceramic core - part 5 : determination of linear expansibility
