Description of the invention: [Technical field to which the invention pertains] The present invention relates to a method for recycling dust ash in a foundry industry, particularly to the use of dust ash materials discarded in the foundry industry as a true strength property. Mineral admixture, or concrete used in engineering backfilling and road foundation, can not only solve the environmental problems of a large number of dust collection ash, but also reduce the amount of expensive raw materials (added materials).
按,於鑄造業之鑄造過程中除會產生廢鑄砂之外,亦 會於產生集塵灰物質,而集塵灰係指金屬基本工業、金屬 製品製造業或機械設備製造修配業在鑄造製程以及金屬 燦煉過程中集塵設備所蒐集之粉末物質。 目前鑄造業集塵灰皆以掩埋方式處理,其處理費用高 且掩埋場容量受限,近年來,亦多有掩埋場因容量飽和而 限制一般事業廢棄物進場。因此,鑄造業集塵灰資源化更 形重要。鑄造業集塵灰之分類係依其使用模砂種類來區 分,由上可知,鑄造業集塵灰之物化性質及無害性與廢鱗 砂相似。但在資源化實際應用上,因其過細的顆粒,用於 混凝土中取代細骨材時,對混凝土之工作性、力學強度、 孔隙結構仍有不利之影響,有其使用上之限制,故集塵灰 之資源化遂徑難覓。 然,本發明人先前針對應用鑄造業廢鑄砂於可控制性 低強度回填材料中的研究,已經申請發明專利而獲准為證 書號第1227220號「應用於可控制性低強度回填材料之骨 材及其處理方法」發明案,其主要以呋喃砂系統、水坡璃 义系統、濕模砂系統、陶竞殼模砂及樹脂砂等數種廢禱砂 5 I3〇7335 之任種,或任二種,或任三種、或任四種或五種等之組 成,經過磁選、篩分及破碎三道特定製程,將廢鑄砂製成 4. 75麵以下之細粒料,摒除粗粒料、鐵塊等雜質對單軸抗 髮強度及流變行為的影響,以產生強度範圍易控制及流動 陡較佳之 CLSM(Controlled Low Strength Materials,簡 稱 CLSM)。According to the casting process in the foundry industry, in addition to the waste cast sand, dust ash will also be produced. The dust ash refers to the metal basic industry, metal products manufacturing or mechanical equipment manufacturing repair industry in the casting process. And the powder material collected by the dust collecting equipment during the metal canning process. At present, the dust collection ash in the foundry industry is treated by landfill, and the treatment cost is high and the capacity of the landfill is limited. In recent years, many landfills have restricted the entry of general business waste due to capacity saturation. Therefore, the recycling of dust collection ash in the foundry industry is more important. The classification of dust collection in the foundry industry is based on the type of sand used. From the above, the physicochemical properties and harmlessness of the dust from the foundry industry are similar to those of waste sand. However, in the practical application of resources, because of its fine particles, when it is used to replace fine aggregates in concrete, it still has an adverse effect on the workability, mechanical strength and pore structure of concrete, and there are restrictions on its use. The recycling of dust and dust is difficult. However, the inventors previously applied for the application of the foundry waste sand in the controllable low-strength backfill material, and have applied for the invention patent and obtained the certificate No. 1227220 "Applying to the controllable low-intensity backfill material. And its treatment method" invention, which mainly uses various kinds of waste prayer sand 5 I3〇7335, such as furan sand system, water slope glass system, wet mold sand system, pottery shell mold sand and resin sand, or Two kinds, or any three, or any four or five kinds of components, after three specific processes of magnetic separation, sieving and crushing, the waste cast sand is made into fine particles of 4.75 faces or less, and coarse aggregates are removed. The influence of impurities such as iron blocks on the uniaxial strength and rheological behavior of the slab, to produce CLSM (Controlled Low Strength Materials, CLSM for short) with easy control of the strength range and steep flow.
所以本發明人再度為鑄造業集塵灰可資源化之途徑 作一分析研究,而於分析研究的過程中,得知一般水泥混 凝土中通常會加入摻料以強化混凝土,而「摻料」根據美 =混凝土學會ACIC125定義為「混凝土組成成分内除水、 月材和水以外的成分」,這些水以外的成分包括了 :礦物 摻料、化學摻料、輸氣劑、纖維等材料。而一般業界所使 用的卜作嵐材料即為礦物摻料的一種。 而卜作嵐材料中所含氧化石夕及氧化鋁能與水泥水化 生成之氫氧化鈣,或外加鹼質物產生緩慢卜作嵐水化反 應,而有類似水泥水化產物之膠結性反應之任何材料均屬 之。而在使用卜作嵐材料方面,天然的卜作嵐材料在義大 利至今仍大量使用。根據統計資料顯示其水泥產量有40 %是使用摻加25%火山灰的天然卜作嵐材料製成的。1971 年已在挪威開始使用矽灰,1863年歐洲開始生產高爐石水 匕而1972及1982分別在加拿大及美國開始使用高爐石 水泥’而1948年美國在建造Hungry Horse水場時就開始 使用飛灰。矽灰、高爐石粉及飛灰均為工業副產品,而掺 加於混凝土中可取代水泥用量不但較為經濟,而且其所含 石夕酸鹽較多,易與水泥水化的生成物氫氧化鈣及水泥中所 含驗性材料反應形成緻密性的矽酸鈣水化物及填充微結@ 6 1307335 構中之孔隙量能達到強度高及耐久 用已漸趨普遍。美國惡凝土學制因此其使 明定必須填加這種礦物摻料以獲得優質=昆2定新規範 加卜作歲材料的優點為·· 犯 ’因為添 (1) 可取代部分水泥’降低成本。 (2) 提高工作度,降低水化熱,可防止裂縫。 (3) 改善棚錢域f,提高贿㈣。 但因石夕灰、祕石粉及飛灰等Therefore, the inventor once again conducted an analysis and research on the way in which the dust collection ash of the foundry industry can be resourced. In the course of analysis and research, it is known that the general cement concrete is usually added with the admixture to strengthen the concrete, and the "mixing" is based on The concrete = concrete society ACIC125 is defined as "components other than water, moon and water in the concrete composition". The components other than water include: mineral admixtures, chemical admixtures, gas carriers, fibers and other materials. The material used in the general industry is a kind of mineral admixture. However, the oxidized stone and alumina contained in the material of the sputum can produce a slow hydration reaction with the calcium hydroxide formed by the hydration of the cement, or the addition of the alkali substance, and any material having a cementitious reaction similar to the cement hydration product belongs to It. In terms of the use of Bu 岚 materials, natural 岚 岚 materials are still widely used in Italy. According to statistics, 40% of its cement production is made from natural materials made from 25% volcanic ash. In 1971, ash was started in Norway. In 1863, blast furnace stone was started in Europe. In 1972 and 1982, blast furnace stone cement was used in Canada and the United States respectively. In 1948, the United States began to use fly ash when building the Hungry Horse water field. . Ash, blast furnace stone and fly ash are industrial by-products, and the addition of cement to concrete can not only replace the amount of cement, but also contains more calcium sulphate, which is easy to be formed with cement hydrated calcium hydroxide. Calcium citrate hydrate and compacted micro-junction formed by the reaction of the materials contained in the cement @ 6 1307335 The amount of pores in the structure can reach high strength and durability has become increasingly common. The American system of eccentric soils therefore makes it necessary to add this mineral admixture to obtain high quality. The advantage of the new standard for the addition of the new material is that it is a crime because it can replace the part of the cement. . (2) Improve work efficiency, reduce hydration heat, and prevent cracks. (3) Improve the money field in the shed and raise the bribe (4). But because of Shi Xi ash, secret stone powder and fly ash, etc.
