【摘要】：磷石膏是生產(chǎn)磷肥、磷酸時(shí)排放的工業(yè)廢渣。我國(guó)磷石膏廢渣的大量排放,環(huán)境污染巨大。但由于磷石膏本身帶有雜質(zhì)且結(jié)構(gòu)不穩(wěn)定,為能被廣泛利用。論文通過(guò)研究將磷石膏變廢為寶,減少環(huán)境危害的同時(shí)節(jié)約天然石膏資源,帶來(lái)經(jīng)濟(jì)效益。本論文具體研究?jī)?nèi)容如下:(1)利用廣義神經(jīng)網(wǎng)絡(luò)指導(dǎo)磷石膏砌塊復(fù)合外加劑及外摻料的配合比實(shí)驗(yàn),最終確定最佳配合比,制備性能優(yōu)良的磷石膏砌塊。(2)進(jìn)行課外市場(chǎng)調(diào)研,借鑒天然石膏生產(chǎn)線估算磷石膏砌塊生產(chǎn)成本。(3)研究磷石膏砌塊的施工工序及工法,測(cè)定了人工、機(jī)械、材料的消耗量并編制施工成本及裝飾裝修成本。(4)匯總磷石膏砌塊技術(shù)、功能及經(jīng)濟(jì)指標(biāo),并與傳統(tǒng)砌塊材料做指標(biāo)對(duì)比。(5)建立符合砌塊材料的比選指標(biāo)體系。利用E-VIKOR混合多屬性群決策法對(duì)砌塊材料做綜合比選研究。本論文可得到主要結(jié)論如下:(1)廣義神經(jīng)網(wǎng)絡(luò)在磷石膏砌塊強(qiáng)度預(yù)測(cè)中誤差波動(dòng)范圍及數(shù)值均在可接受有效范圍內(nèi),預(yù)測(cè)結(jié)果精度較高,證明廣義神經(jīng)網(wǎng)絡(luò)在復(fù)合外加劑及外摻料配合比實(shí)驗(yàn)中的非線性映射能力、容錯(cuò)性和自學(xué)性,提高實(shí)驗(yàn)水平和效率。(2)磷石膏砌塊復(fù)合外加劑及外摻料最佳配合比為水膏比0.273,聚乙烯醇摻量為0.1%,聚羧酸摻量為0.7%,硅灰摻量為5.0%,陶粒摻量10.0%。此配合比制備出的磷石膏砌塊抗壓強(qiáng)度達(dá)到12-18MPa,抗折強(qiáng)度達(dá)到3-4MPa。(3)規(guī)格為666×500×100mm的磷石膏砌塊在40%的利潤(rùn)率情況下不含稅單價(jià)為350.83元/m~3,生產(chǎn)成本略高于傳統(tǒng)砌塊材料。100mm厚磷石膏砌塊墻體的施工綜合單價(jià)為482.96元/m~3,與傳統(tǒng)砌塊相比具有一定優(yōu)勢(shì)。(4)運(yùn)用E-VIKOR混合多屬性法得到的砌塊材料折中排序結(jié)果合理可信,在不同決策機(jī)制下,磷石膏砌塊材料的計(jì)算值均為最小值,為最優(yōu)折中方案,驗(yàn)證了磷石膏砌塊材料較其他傳統(tǒng)砌塊材料的優(yōu)越性、經(jīng)濟(jì)性及局限性。
[Abstract]:Phosphogypsum is a kind of industrial waste residue which is discharged in the production of phosphate fertilizer and phosphoric acid. A large amount of phosphogypsum waste residue is discharged in China, which causes huge environmental pollution. However, the phosphogypsum itself has impurities and unstable structure. In order to be widely used in this paper, the phosphogypsum can be changed into a treasure through research, which can reduce the environmental harm and save the natural gypsum resources at the same time. The concrete research contents of this paper are as follows: 1) using the generalized neural network to guide the experiment of the mixture ratio of phosphogypsum block compound admixture and admixture, finally determine the best mix ratio. Preparation of phosphogypsum block with excellent performance. (2) carry out extracurricular market investigation, use natural gypsum production line for reference to estimate the production cost of phosphogypsum block.) study the construction procedure and method of phosphogypsum block. Consumption of materials and compilation of construction cost and decoration cost. 4) Summary of phosphogypsum block technology, function and economic index, And compared with the traditional block material as index. 5) to establish the index system of comparison and selection according to block material. By using E-VIKOR mixed multi-attribute group decision method, the comprehensive comparison and selection of block material is studied. The main conclusions in this paper are as follows: 1) Generalized. In the prediction of the strength of phosphogypsum block, the range of error fluctuation and the value of the neural network are within the acceptable effective range. The accuracy of the prediction results is high, which proves the nonlinear mapping ability, fault tolerance and self-learning of the generalized neural network in the experiments of compound admixture and admixture proportion. The optimum mixture ratio of phosphogypsum block admixture and admixture is water / gypsum ratio 0.273, polyvinyl alcohol 0.1, polycarboxylic acid 0.7, silica fume 5.0 and ceramsite 10.0. The gypsum block with 666 脳 500 脳 100mm specifications has a compressive strength of 12-18MPa and a flexural strength of 3-4MPa.m3. Under the condition of 40% profit margin, the unit price is 350.83 yuan / m ~ (-3), and the production cost is slightly higher than that of the traditional block material .100mm thick phosphogypsum block wall. The comprehensive unit price is 482.96 yuan / mm3, which has a certain advantage compared with the traditional block.) the result of eclectic sorting of block materials obtained by E-VIKOR mixed multi-attribute method is reasonable and reliable. Under different decision-making mechanisms, the calculation value of phosphogypsum block material is the minimum value, which is the optimal compromise scheme, which verifies the superiority, economy and limitation of phosphogypsum block material compared with other traditional block materials.
