防腐材料

This paper mainly studies effect and influence factor that typical corrosive medium (muriatic acid, vitriol, nitric acid, sodium hydroxide, sodium chloride etc.), consistence and condition temperature acts on the material coated on castiron centrifugal interface (PFEP, PPS, CPE, remodeled epoxy). It is studied that powder electrostatic spray, suspend fluid spray, suspend fluid electrophoresis underside coat etc. technics influences on coat quality coated with above four anticorrosive material. The property analysis is done that above four anticorrosive material and three coat technics adapt to centrifugal pump frame and running dynamic condition. In addition, the effect is introduced that castiron centrifugal coated anticorrosive material is used in coal water with alum.

In this paper, based on the analysis of the effects of the structure of UASB reactors and the processes of reactions on corrosion, the corrosion mechanism is discussed, and three measures to prevent the corrosion of the UASB reactor are presented, I.e., improvement of the anticor rosion design, application of anticorrosion materials and preservative treatment of the equipment.

由于上流式厌氧污泥床UASB内发生的反应主要属于化学过程和生物过程，因此UASB反应器内壁极易发生腐蚀，从而影响反应效果，降低设备使用寿命，增加维护费用在分析了上流式厌氧污泥床反应器的结构与工艺对腐蚀的作用的基础上，讨论了腐蚀机理，提出了应在改进防腐设计、采用耐腐蚀材料和对设备进行防腐处理等3个方面采取措施，从而防止UASB反应器内的腐蚀现象

Glass-epoxy system used for steel parts, casting a variety of mechanical parts or electronic components as a sealing material, the preparation of polyamide anti-corrosion paintings, as well as a zinc-rich epoxy primer, epoxy primer Iron Cloud, epoxy stone painting, epoxy paint, bituminous coal, chemical corrosion, paint, etc. have also been used widely

用于制环氧玻璃钢制件，浇铸各种机械零件或作为电子元件的密封材料，配制聚酰胺防腐涂料，以及用作环氧富锌底漆、环氧云铁底漆、环氧石漆、环氧煤沥青漆等，在化工防腐，涂料等方面也有广泛用途。

所有的产品都使用合格的防腐材料，经久耐用。

In recent years, some non-metallic corrosion materials, such as plastic, fibreglass, glass, ceramics and not revealed sexual graphite, in the chemical production of a wide range of applications received and achieved remarkable results.

近年来，一些非金属防腐材料，如塑料，玻璃钢，玻璃，陶瓷和不透性石墨等，在化学生产中得到的广泛的应用，取得了显著的效果。

Especially for the of concrete frame structure building and steel frame structure building without traditional brittle filler wall, using steel-mesh-cement-mortar plastering as inter insulating layer connected with the main structure to forming flexible composite wall can meet the requirement of saving 65% of energy for wall in the cold region and ensure the safety of the device installed on the opening to shield sunshine and facilitate its installation.

聚酯薄膜和聚丙烯酸酯乳液都是耐久性非常好的材料，可达到40年有效防腐期，有希望达到50年的有效防腐期，远远高于现在的钢材防腐蚀涂层十几年的寿命，在粘接强度满足使用要求条件下，及提高混凝土构件的柔性，对社会的可持续发展具有重要意义。

Set up in 1988, Zhangjiagang Orient Antiseptic Material Limited Corporation is the largest and most professional domestic manufacturer producing vehicle paint fog flocculant,paint remover,damping cushion,all kinds of vehicle glue, glutinous gauze and its attachment.

公司简介：张家港市东方防腐材料有限公司创建于1988年，是国内生产车用漆雾凝聚剂、脱漆剂、阻尼减震胶片、各类车用胶、粘性纱布等附件的最大、最专业生产厂家。

Anticorrosive process of surface evaporation air cooler using LLSTD-1 as coating media,which solves two major difficult problems in large scale bundle anticorrosive techniques:performance requirements on coating materials (heat conduction,high temperature resistance,oil-proof and scale inhibition)and the coating method on surface evaporation air cooler bundles.

以LLSID-1涂料为涂层介质对大型表面蒸发空冷器管束进行防腐处理，解决了大型管束防腐的两大难题，一是对涂层材料的性能要求(耐腐、耐温、耐油、阻垢、传热效果好)；二是解决了大型管束防腐工艺(用什么方法将涂料涂装在表面蒸发空冷器管束上)。

Power plant smoke stack in the process, as a result of changes in working conditions, flue gas temperature between 40 ~ 150 ℃, the incident state will exceed 180 ℃, or even higher, and therefore requested the anti-corrosion material has excellent heat resistance.

电厂烟囱在排烟过程中，由于工况变化，烟气温度在40~150℃之间，事故状态下将超过180℃，甚至更高，因此要求防腐材料具有优良的耐热性。

Indoor air sources of formaldehyde are mainly in the following aspects : 1, the plywood used for interior decoration, Ximugongban, medium density fibreboard and shaving board, and other artificial plate because formaldehyde has strong sexual bond, has strengthened plate and the hardness control, corrosion functions, Therefore, the current production of imitation board use Jiaonianji merits to formaldehyde as the main ingredients thiourea aldehyde resins, plate, residual and did not participate in the response formaldehyde will gradually release of the surrounding environment is a indoor air formaldehyde main ;2, using imitation board manufacturing furniture, some manufacturers in the pursuit of profit, the use of unqualified plate. In preliminary front face material reuse inferior glue, the manufacturing processes are not standardized, as a result of customers buying home, to buy a small emission points ;3, containing formaldehyde content and may distribute to the outside other categories decorative materials, such as stickers Qiangbu, with wallpapers, chemical fiber carpet, foam, paint and paint, etc.;4, combustion, emit formaldehyde certain materials, such as cigarettes and some organic materials.

室内空气中的甲醛来源主要有以下几个方面：1、用作室内装饰的胶合板、细木工板、中密度纤维板和刨花板等人造板材，因为甲醛具有较强的粘合性，还具有加强板材的硬度及防虫、防腐的功能，所以目前生产人造板使用的胶粘剂是非曲直以甲醛为主要成分的脲醛树脂，板材中残留的和未参与反应的甲醛会逐渐向周围环境释放，是形成室内空气中甲醛的主体；2、用人造板制造的家具，一些厂家为了追求利润，使用不合格的板材，在粘接贴面材料时再使用劣质胶水，制造工艺不规范，结果顾客买回家去，等于买回了一个小型废气排放站；3、含有甲醛成分并有可能向外界散发的其他各类装饰材料，比如贴墙布，贴墙纸，化纤地毯、泡沫塑料、油漆和涂料等；4、燃烧后会散发甲醛的某些材料，比如香烟及一些有机材料。
