產(chǎn)品介紹　　硫酸是一種無(wú)機化合物，化學(xué)式是H2SO4，硫的最重要的含氧酸。純凈的硫酸為無(wú)色油狀液體，10.36℃時(shí)結晶，通常使用的是它的各種不同濃度的水溶液，用塔式法和接觸法制取。前者所得為粗制稀硫酸，質(zhì)量分數一般在75%左右;后者可得質(zhì)量分數98.3%的濃硫酸，沸點(diǎn)338℃，相對密度1.84。　　硫酸是一種最活潑的二元無(wú)機強酸，能和絕大多數金屬發(fā)生反應。高濃度的硫酸有強烈吸水性，可用作脫水劑，碳化木材、紙張、棉麻織物及生物皮肉等含碳水化合物的物質(zhì)。與水混合時(shí)，亦會(huì )放出大量熱能。其具有強烈的腐蝕性和氧化性，故需謹慎使用。是一種重要的工業(yè)原料，可用于制造肥料、藥物、炸藥、顏料、洗滌劑、蓄電池等，也廣泛應用于凈化石油、金屬冶煉以及染料等工業(yè)中。常用作化學(xué)試劑，在有機合成中可用作脫水劑和磺化劑。物理性質(zhì) 　　純硫酸一般為無(wú)色油狀液體，密度1.84 g/cm3，沸點(diǎn)337℃，能與水以任意比例互溶，同時(shí)放出大量的熱，使水沸騰。加熱到290℃時(shí)開(kāi)始釋放出三氧化硫，最終變成為98.54%的水溶液，在317℃時(shí)沸騰而成為共沸混合物。硫酸的沸點(diǎn)及粘度較高，是因為其分子內部的氫鍵較強的緣故。由于硫酸的介電常數較高，因此它是電解質(zhì)的良好溶劑，而作為非電解質(zhì)的溶劑則不太理想。硫酸的熔點(diǎn)是10.371℃，加水或加三氧化硫均會(huì

產(chǎn)品介紹　　飼料添加劑是指在飼料生產(chǎn)加工、使用過(guò)程中添加的少量或微量物質(zhì)，在飼料中用量很少但作用顯著(zhù)。飼料添加劑是現代飼料工業(yè)必然使用的原料，對強化基礎飼料營(yíng)養價(jià)值，提高動(dòng)物生產(chǎn)性能，保證動(dòng)物健康，節省飼料成本，改善畜產(chǎn)品品質(zhì)等方面有明顯的效果。注意事項　　1、在飼料添加劑中濫用抗生素與激素在早期飼料添加劑的生產(chǎn)中，有人用低劑量的抗生素或磺胺類(lèi)藥物來(lái)防止畜禽的疾病或腹瀉。這種低劑量的抗生素會(huì )破壞自然環(huán)境中微生物(包括病原微生物)間的生態(tài)平衡，在食品中有殘留，將嚴重影響人的疾病治療及人的遺傳。　　2、某些微量元素的用量過(guò)多或不足，在飼料添加劑中常用的微量元素有鐵、銅、錳、鋅、碘、硒等，這些元素進(jìn)人體內后以離子、分子或結構復雜的化合物的狀態(tài)存在，不同狀態(tài)下所起的生化作用也不同。太少會(huì )產(chǎn)生缺乏癥，太多又會(huì )引起中毒或產(chǎn)生不平衡。所以必須含量適當，而且混合均勻，否則會(huì )起相反作用。　　3、過(guò)分夸大飼料添加劑的作用，飼料添加劑對平衡日糧，促進(jìn)畜禽生產(chǎn)、生長(cháng)的效果是肯定的。一般能比不使用添加劑的對照組增產(chǎn)5%-25%。但有的產(chǎn)品在廣告宣傳時(shí)，過(guò)分夸大其作用，對這些不切實(shí)際的宣傳，應該引起警惕。 </div>   <a class="link"
