中國經(jīng)濟網(wǎng)記者今日報道,水泥砂漿防腐鋼管不斷增加地選用復合資料或復合構(gòu)造 。這些資料和構(gòu)造要具有杰出的介電功能、物理功能、安穩(wěn)的化學功能和較寬的溫度適應(yīng)規(guī)模等 。Composite materials or composite structures are increasingly used for mortar corrosion resistant steel pipes. These data and structures should have outstanding dielectric, physical, stable chemical and wide temperature adaptability.1、外壁防腐涂層:管道外壁涂層資料品種和運用條件 。①內(nèi)壁防腐涂層:為了避免管內(nèi)腐蝕、降低摩擦阻力、進步輸量而涂于管子內(nèi)壁的薄膜 。常用的涂料有胺固化環(huán)氧樹脂和聚酰胺環(huán)氧樹脂,涂層厚度為0.038~0.2毫米 。為保證涂層與管壁粘結(jié)結(jié)實,有必要對管內(nèi)壁進行外表處理 。70年代以來趨向于管內(nèi)、外壁涂層選用一樣的資料,以便管內(nèi)、外壁的涂敷一起進行 。1. The outer wall anticorrosive coating: the variety and application condition of the coating on the outer wall of the pipeline. (1) Anti-corrosive coating on the inner wall of the pipe: the film applied on the inner wall of the pipe to avoid corrosion, reduce friction resistance and improve transportation. The commonly used coatings are amine cured epoxy resin and polyamide epoxy resin, the thickness of the coating is 0.038-0.2 mm. In order to ensure the adhesion between the coating and the tube wall, it is necessary to treat the inner surface of the tube. Since the 1970s, there has been a tendency to use the same materials for inner and outer wall coatings so that they can be applied together.②防腐保溫涂層:在中、小口徑的熱輸原油或燃料油的管道上,為了削減管道向土壤散熱,在管道外部加上保溫文防腐的復合層 。常用的保溫資料是硬質(zhì)聚氨脂泡沫塑料,適用溫度為-185~95℃ 。這種資料質(zhì)地松軟,為進步其強度,在隔熱層外面加敷一層高密度聚乙烯層,構(gòu)成復合資料構(gòu)造,以避免地下水進入保溫層內(nèi) 。(2) Anti-corrosion and heat preservation coating: In order to reduce the heat dissipation from the pipeline to the soil, a composite coating of heat preservation and anti-corrosion was added on the outside of the pipeline for medium and small diameter heat-transfer crude oil or fuel oil pipeline. The commonly used thermal insulation material is rigid polyurethane foam, and the temperature is between 18 and 95 degrees. In order to improve its strength, a layer of high density polyethylene (HDPE) is added to the insulation layer to form a composite data structure to prevent groundwater from entering the insulation layer.2、如外護管是聚乙烯管,無需再做防腐聚乙烯無臭,無毒,手感似蠟,具有優(yōu)秀的耐低溫功能(*運用溫度可達-70~-100℃),化學安穩(wěn)性好,本領(lǐng)大多數(shù)酸堿的腐蝕(不耐具有氧化性質(zhì)的酸),常溫下不溶于通常溶劑,吸水性小,但由于其為線性分子可緩慢溶于某些有機溶劑,且不發(fā)作溶脹,電絕緣功能優(yōu)秀 。2. If the outer protective tube is polyethylene tube, no need to do anticorrosive polyethylene odorless, non-toxic, feel like wax, with excellent low-temperature resistance (* the use of temperature can reach - 70 ~ - 100 degrees C), chemical stability, the ability of most acid-base corrosion (not resistant to oxidizing acid), insoluble in ordinary solvents at room temperature, water absorption is small, but Because it is a linear molecule which can be slowly soluble in some organic solvents and does not swell, it has excellent electrical insulation function.
