【摘要】：我國(guó)浮法玻璃普遍存在滲錫量大,虹彩嚴(yán)重的情況,制約了我國(guó)玻璃制品的精深加工。為了解決這一問(wèn)題,提升我國(guó)浮法玻璃的市場(chǎng)競(jìng)爭(zhēng)力,必須針對(duì)該問(wèn)題進(jìn)行研究,提出降低滲錫量和減輕玻璃虹彩的有效措施。研究發(fā)現(xiàn),往錫液中加金屬鐵能有效的降低玻璃表面的滲錫量,進(jìn)而降低玻璃鋼化虹彩出現(xiàn)的概率。 本課題利用x射線熒光分析儀(XRF)、電子探針(EPMA、X射線光電子能譜(XPS)研究錫液中加鐵對(duì)玻璃表面錫擴(kuò)散的影響。研究從兩個(gè)方面展開(kāi)：一是直接對(duì)生產(chǎn)線上的玻璃樣品進(jìn)行分析研究；另一方面是利用自行搭建的模擬浮法玻璃成型裝置制樣,對(duì)玻璃樣品進(jìn)行分析研究。實(shí)驗(yàn)中還對(duì)錫槽加鐵引起玻璃下表面微泡的原因進(jìn)行了簡(jiǎn)單的分析。 研究發(fā)現(xiàn)實(shí)際生產(chǎn)中往錫液中加適量的金屬鐵,不僅能有效的降低玻璃表面的滲錫量、錫的滲入深度及玻璃表面Sn2+的相對(duì)含量,還能有效的降低玻璃鋼化虹彩等級(jí)。錫液中加金屬鐵能促使玻璃下表層滲入鐵增多,滲入的鐵主要以Fe3+的形式存在。鐵不僅能優(yōu)先與氧氣反應(yīng),還能把錫氧化物還原回錫單質(zhì),從而降低玻璃表面錫的滲入量和滲入深度。同時(shí)錫液中反應(yīng)生成的Fe3+還能把Sn2+氧化成Sn4+,擴(kuò)散到玻璃表層的Fe3+也能把滲入玻璃表層的Sn2+氧化成Sn4+,從而增加玻璃表層中Sn4+的相對(duì)含量。對(duì)實(shí)驗(yàn)室制樣分析研究發(fā)現(xiàn),往錫液中加金屬鐵時(shí),隨著加鐵量(0%-0.8%)的增加,玻璃表層滲錫量先減少后增大,進(jìn)入玻璃表層中的Sn2+相對(duì)含量也是先減少后增大,而Sn4+相對(duì)含量增加先增大后減少。加鐵量為0.4%時(shí),滲錫量最小,約為17.30ug/cm2,進(jìn)入玻璃表層的Sn4+的相對(duì)含量最大,約為96.12%；玻璃下表面鐵滲入量隨著錫液中加鐵量的增多而增多；加鐵量相同,延長(zhǎng)玻璃與錫液的接觸時(shí)間,滲錫量增多,進(jìn)入玻璃中的鐵含量反而降低。 實(shí)際生產(chǎn)中發(fā)現(xiàn),往錫液中加鐵控制玻璃鋼化虹彩,加入鐵的量有一個(gè)最優(yōu)范圍,當(dāng)錫液中鐵含量控制在0.03%左右時(shí),生產(chǎn)出的玻璃鋼化虹彩等級(jí)低；當(dāng)錫液中加入的鐵的量太少或過(guò)多時(shí),生產(chǎn)出的玻璃進(jìn)行鋼化后虹彩嚴(yán)重。這一生產(chǎn)實(shí)踐正好驗(yàn)證了前面的研究成果：生產(chǎn)中加入適量的鐵不僅減少了玻璃表面滲錫量和Sn2+的相對(duì)含量,還減輕了玻璃虹彩,少加或多加都不利于玻璃表面滲錫量的減少。實(shí)踐中還發(fā)現(xiàn)采取少量多次的方式往錫液中加鐵能大大降低玻璃下表面氣泡的產(chǎn)生。
[Abstract]:The high tin permeation and iridescent are common in float glass in China, which restricts the deep processing of glass products in China. In order to solve this problem and improve the market competitiveness of float glass in China, it is necessary to study the problem and put forward effective measures to reduce the amount of tin permeation and lighten the iris of glass. It is found that the addition of metal iron to the tin solution can effectively reduce the amount of tin permeation on the glass surface and thus reduce the probability of the appearance of the glass tempered iris. The effect of iron addition on tin diffusion on glass surface was studied by using X-ray fluorescence analyzer (XRF),) electron probe (EPMA,X) photoelectron spectroscopy (XPS). The research is carried out from two aspects: one is to analyze the glass samples in the production line directly; the other is to analyze and study the glass samples by using the self-built simulated float glass forming device. The causes of the microbubbles on the glass surface caused by the addition of iron in the tin bath were also analyzed. It is found that adding appropriate amount of metal iron to the tin solution in actual production can not only effectively reduce the amount of tin permeation on the glass surface, the penetration depth of tin and the relative content of Sn2 on the glass surface, but also effectively reduce the grade of glass tempered iridescent. The addition of metal iron in the tin solution can increase the amount of iron infiltrated in the surface layer of glass, and the infiltrated iron mainly exists in the form of Fe3. Iron can not only preferentially react with oxygen, but also reduce tin oxide back to tin element, thus reducing the amount and depth of tin infiltration on glass surface. At the same time, Fe3 can oxidize the Sn2 to Sn4, and the Fe3 diffused to the glass surface can also oxidize the Sn2 infiltrated into the glass surface to Sn4, thus increasing the relative content of Sn4 in the glass surface. It is found that with the increase of iron content (0% -0.8%), the amount of tin permeated in the glass surface decreases first and then increases, and the relative content of Sn2 entering the glass surface decreases first and then increases when the metal iron is added to the tin solution. The relative content of Sn4 increased first and then decreased. When the amount of iron added is 0.4, the amount of tin permeation is the smallest, about 17.30ugr / cm ~ 2, and the relative content of Sn4 entering the surface of glass is the largest, about 96.12.The amount of iron infiltration on the surface of the glass increases with the increase of the amount of iron added into the tin solution; the amount of iron added is the same. When the contact time between glass and tin solution is prolonged, the amount of tin permeation increases and the content of iron entering the glass decreases. In practical production, it is found that adding iron to the molten tin to control the glass tempered iridescent has an optimal range. When the iron content in the molten tin is controlled at about 0.03%, the grade of the glass tempered iridescent is low. When too little or too much iron is added to the molten tin, the resulting glass is tempered and ironed seriously. This production practice just verifies the previous research results: the addition of appropriate amount of iron in production not only reduces the amount of tin permeation on glass surface and the relative content of Sn2, but also lightens the glass iris, and less or more addition is not conducive to the reduction of the amount of tin permeation on glass surface. It is also found that adding iron to the tin solution in a small amount of time can greatly reduce the formation of bubbles on the surface of the glass.
