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(lǐng)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(fù)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(jīng)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(xué)或電化學(xué)反應(yīng)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(yīng)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(jié)構(gòu),海洋輸水打樁等管道工程領(lǐng)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(jié)合成了一個整體,從而使該涂層具有熔結(jié)環(huán)氧粉末(FBE)涂層和聚乙烯涂層的優(yōu)點。熔結(jié)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(jié)環(huán)氧經(jīng)化學(xué)反應(yīng)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(jié)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(chǎn),到2020年實現(xiàn)年產(chǎn)能9000萬噸,鐵礦石平均品位高達66.7%,是世界上品質(zhì)*的鐵礦之一三層結(jié)構(gòu)聚乙烯防腐層(3PE)綜合了熔結(jié)環(huán)氧粉末涂層和擠壓聚乙烯兩種防腐層的優(yōu)良性質(zhì),將熔結(jié)環(huán)氧粉末涂層的界面特性和耐化學(xué)特性,與擠壓聚乙烯防腐層的機械保護特性等優(yōu)點結(jié)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. ![]() ![]() 環(huán)氧粉末防腐螺旋鋼管 ??給水鋼管內(nèi)外涂塑工藝是目前國內(nèi)*的防腐技術(shù),它集鋼材優(yōu)越的機械性能與高分子材料卓越的耐化學(xué)腐蝕性能于一體,極大地延長了鋼管的使用壽命,具有獨特的防腐耐酸堿性、抗磨損、無結(jié)垢、助潤滑、耐負壓等優(yōu)越性,可替代襯塑管、鍍鋅管、不銹鋼管、銅管等。將高分子防腐粉末涂料,通過特殊的設(shè)備將其均勻地涂覆于金屬管道的內(nèi)外表面,經(jīng)固化和塑化后在金屬管道內(nèi)外表面形成一層均勻、致密、光滑的塑料涂層,成為一種新型的鋼塑復(fù)合管。 ??直縫焊管生產(chǎn)工藝簡單,生產(chǎn)效率高,成本低,發(fā)展較快。螺旋焊管的強度一般比直縫焊管高,能用較窄的坯料生產(chǎn)管徑較大的焊管,還可以用同樣寬度的坯料生產(chǎn)管徑不同的焊管。但是與相同長度的直縫管相比,焊縫長度增加30~100%,而且生產(chǎn)速度較低。因此,較小口徑的焊管大都采用直縫焊,大口徑焊大口徑厚壁螺旋焊管展望二季度,國標(biāo)螺旋鋼管行業(yè)產(chǎn)能過剩、螺旋鋼管價格低迷、微利狀況不會發(fā)生根本改變。 |
