燕趙新聞網(wǎng)今日報道：環(huán)氧粉末防腐鋼管由于聚酯樹脂帶有極性基團，所以上粉率比環(huán)氧樹脂高，烘烤過程中不易泛黃，光澤度高，流平性好，漆膜豐滿，顏色淺等特性，因而具有很好的裝飾性。一般多用于電冰箱、洗衣機、吸塵器、儀表外殼、自行車、家具等領域。丙烯酸酯粉涂料。丙烯酸樹脂粉末涂料有熱塑性和熱固性兩種。熱固性丙烯酸樹脂粉末涂料*的優(yōu)點是具有優(yōu)良的耐候性、保色性、耐污染性、金屬附著力強、涂膜外觀優(yōu)異，適用作裝飾性粉末涂料。熱塑性粉末涂料。熱塑性粉末涂料是1950年開始出現(xiàn)的，它在噴涂溫度下溶融，冷卻時凝固成膜。由于加工和噴涂方法簡單，粉末涂料只需加熱熔化、流平、冷卻或萃取凝固成膜即可，不需要復雜的固化裝置。大多使用的原料都是市場上常見的聚合物，多數(shù)條件下都可滿足使用性能的要求。但也存在某些不足，諸如熔融溫度高，著色水平低，與金屬表面粘著性差等。

Epoxy powdered anticorrosive steel pipes have better decorative properties than epoxy due to their polar groups, high flour loading, less yellowing, high gloss, good leveling, fullness of paint film, light color and so on. Generally used in refrigerators, washing machines, vacuum cleaners, instrument housings, bicycles, furniture and other fields. Acrylic powder coating. Acrylic resin powder coating has two kinds of thermoplastic and thermosetting. Thermosetting acrylic powder coatings * have the advantages of excellent weather resistance, color retention, pollution resistance, strong metal adhesion, excellent appearance of the film, suitable for decorative powder coatings. Thermoplastic powder coatings. Thermoplastic powder coatings began to appear in 1950. It melts at spraying temperature and solidifies into films when cooled. Because of the simplicity of the processing and spraying methods, powder coatings need only be melted, leveled, cooled or solidified into films by heating, or solidified by extraction, without complicated solidification devices. Most of the raw materials used are common polymers on the market, which can meet the performance requirements under most conditions. But there are also some shortcomings, such as high melting temperature, low coloring level, poor adhesion with metal surface and so on.

TPEP防腐鋼管是指經過防腐工藝加工處理，可有效防止或減緩在運輸與使用過程中發(fā)生化學或電化學反應發(fā)生腐蝕現(xiàn)象的鋼制管道。防腐鋼管母材包括螺旋管，直縫管，無縫管等，在我國廣泛應用于長距離輸水、石油、化工、天然氣、熱力、污水處理、水源、橋梁、鋼結構，海洋輸水打樁等管道工程領域。TPEP防腐鋼管防腐層特點介紹：TPEP涂層越性能主要是由于它將底層環(huán)氧粉末、中間層粘接劑和外層聚乙烯有機地結合成了一個整體，從而使該涂層具有熔結環(huán)氧粉末(FBE)涂層和聚乙烯涂層的優(yōu)點。熔結環(huán)氧通過其活性基團與鋼管表面活化離子作用形成離子鍵以及物理嵌合力，使之牢固粘附在金屬基體表面。由聚乙烯改性制得共聚物粘接劑，不僅具有與熔結環(huán)氧經化學反應形成共價鍵（酯鍵）的能力，而且通過接枝改性，破壞了聚乙烯材料的電子偶極平衡，使熔結環(huán)氧與共聚物分子間力度增強，有效提高了兩者界面間粘接強度。該項目將在未來4年逐步達產，到2020年實現(xiàn)年產能9000萬噸，鐵礦石平均品位高達66.7%，是世界上品質*的鐵礦之一三層結構聚乙烯防腐層（3PE）綜合了熔結環(huán)氧粉末涂層和擠壓聚乙烯兩種防腐層的優(yōu)良性質，將熔結環(huán)氧粉末涂層的界面特性和耐化學特性，與擠壓聚乙烯防腐層的機械保護特性等優(yōu)點結合起來，從而顯著改善了各自的性能。淡季行情下，市場信心不足，不可盲目看多。

TPEP anticorrosive steel pipe is a kind of steel pipe which is processed by anticorrosive technology and can effectively prevent or slow down the corrosion of chemical or electrochemical reactions during transportation and use. The base material of anticorrosive steel pipe includes spiral pipe, straight seam pipe, seamless pipe and so on. It is widely used in long-distance water conveyance, petroleum, chemical industry, natural gas, thermal power, sewage treatment, water source, bridge, steel structure, marine water conveyance piling and other pipeline engineering fields in China. Features of TPEP anticorrosive coating for steel pipe: The better performance of TPEP coating is mainly due to its organic combination of bottom epoxy powder, intermediate adhesive and outer polyethylene, so that the coating has the advantages of fused epoxy powder (FBE) coating and polyethylene coating. Melting epoxy resin bonds with activated ions on the surface of steel tube through its active groups to form ion bonds and physical bonding force, making it firmly adhere to the metal substrate surface. The copolymer adhesive prepared by modification of polyethylene not only has the ability to form covalent bond (ester bond) with fused epoxy by chemical reaction, but also destroys the electronic dipole balance of polyethylene material by graft modification, so as to enhance the intermolecular force between fused epoxy and copolymer, and effectively improve the bonding strength between them. The project will gradually reach production capacity in the next four years. By 2020, the annual production capacity will reach 90 million tons, and the average grade of iron ore will reach 66.7%. It is one of the world's iron ores with high quality. The interfacial characteristics and chemical resistance are combined with the mechanical protection characteristics of extruded polyethylene coatings, thus significantly improving their performance. In the off-season market, market confidence is not enough and we should not blindly see much.
衛(wèi)生級環(huán)氧粉末防腐管過磅價格環(huán)氧煤瀝青防腐涂料是一種雙組份的胺固化液體環(huán)氧型防腐涂料，它以環(huán)氧樹脂和煤焦油為基料進行深加工而得。此種涂料在加工時添加了云母粉填料從而對它的的絕緣防腐性能有了很大的提升。厚壁螺旋鋼管若擠壓力過小，形成共同晶體的數(shù)量就小，焊縫金屬強度下降，受力后會產生開裂;如果擠壓力過大，將會使熔融狀態(tài)的金屬被擠出焊縫，不但降低了焊縫強度，而且會產生大量的內外毛刺，甚至造成焊接搭縫等缺陷。經過表面處理的鋼管采用無污染的熱源均勻加熱。維修簡便，主要用途及適用范圍，外鍍鋅內涂塑復合管由于是通過粒度極小，形成一條線。易爆的特定場所，也叫石油天然氣工業(yè)輸送鋼管交貨技術條件*部分，由于工藝的改進，適應埋地和潮濕環(huán)境，專業(yè)生產大口徑厚壁螺旋管，總之，彎曲等外來影響。環(huán)氧粉末防腐鋼管在發(fā)達國家現(xiàn)已被廣泛運用并且比較老練。環(huán)氧粉末一直是選用靜電噴涂工藝涂敷。因為環(huán)氧粉末浸塑工藝受附著力問題困擾，環(huán)氧粉末的浸塑始終沒能廣泛運用。近年來隨著環(huán)氧粉末浸塑專用磷化液開發(fā)成功，霸占了環(huán)氧粉末浸塑工藝的附著力難題，環(huán)氧粉末的浸塑這一新興工藝開始推行。
