大燕網(wǎng)資訊日前獲悉：高密度聚氨酯發(fā)泡保溫鋼管一般用在市政及各大建筑供暖給排水上面，它是外壁涂裝高附著力、抗沖擊性、防腐耐候型的保溫材料，內(nèi)壁涂裝高附著力、防腐的熱塑性粉末涂料。采用噴砂化學(xué)雙重前處理、預(yù)熱、內(nèi)涂裝、外涂裝、固化、后處理等工藝制成。大口徑保溫鋼管的管壁光潔、排水性能好、流體阻力小、不結(jié)垢是相比于其它管道的大優(yōu)點，可以極大程度的降低損失。同時，大口徑保溫鋼管的線性膨脹系數(shù)非常小，這就使其作為主干輸水管非常有利，大大克服了其他塑料和普通管材線性膨脹系數(shù)大的缺陷。

Dayan. com recently learned that high-density polyurethane foamed insulating steel pipes are generally used in municipal and major buildings for heating, water supply and drainage. They are high adhesion, impact resistance, anti-corrosion and weatherproof insulation materials on the outer wall, and high adhesion, anti-corrosion thermoplastic powder coatings on the inner wall. It is made by sandblasting chemical double pretreatment, preheating, internal coating, external coating, curing and post-treatment. Compared with other pipelines, large-caliber insulation steel pipe has the advantages of smooth wall, good drainage performance, low fluid resistance and no scaling, which can greatly reduce the loss. At the same time, the linear expansion coefficient of large diameter thermal insulation steel pipe is very small, which makes it very advantageous as the main water pipeline, and greatly overcomes the defects of other plastics and ordinary pipes with large linear expansion coefficient.

預(yù)制直埋保溫管作為建筑保溫防水一體化材料，聚氨酯硬泡打破了傳統(tǒng)建材功能單一——防水的不保溫、保溫的不防水，防水層一旦出現(xiàn)滲漏保溫層隨即失去保溫功能的通bing。與其他單功能保溫或防水材料相比，聚氨酯硬泡具有明顯的優(yōu)勢： 1.聚氨酯硬泡具有一材多用的功能，同時具備保溫、防水、隔音、吸振等諸多功能。 2.保溫性能卓越，是目前國內(nèi)所有建材中導(dǎo)熱系數(shù)*、熱阻值*的保溫材料，導(dǎo)熱系數(shù)僅為EPS發(fā)泡聚苯板的一半。 3.聚氨酯硬泡體連續(xù)致密的表皮和近于100%的高強度互聯(lián)壁閉孔，具有理想的不透水性。采用噴涂法施工達到防水保溫層連續(xù)無接縫，形成無縫屋蓋和整體外墻保溫殼體，防水抗?jié)B性能優(yōu)異。 4.超強的自黏性能(無需任何中間黏結(jié)材料),與屋面及外墻黏結(jié)牢固，抗風(fēng)揭和抗負(fù)風(fēng)壓性能良好；整體噴涂施工，完全消除“熱節(jié)"和“冷橋";柔性漸變技術(shù)可有效阻止防水層開裂；機械化作業(yè)、自動配料、質(zhì)量均一、施工快、周期短。

Prefabricated directly buried insulating pipes as building insulation and waterproofing integrated materials, polyurethane rigid foam breaks the traditional building materials function of single - waterproof non-thermal insulation, thermal insulation non-waterproof, waterproof layer once there is leakage insulation layer immediately lose the thermal insulation function of the through bing. Compared with other single-function heat preservation or waterproof materials, polyurethane rigid foam has obvious advantages: 1. Polyurethane rigid foam has many functions, such as heat preservation, waterproof, sound insulation, vibration absorption and so on. 2. Excellent thermal insulation performance, is the thermal conductivity *, thermal resistance value * of all domestic building materials, thermal conductivity is only half of EPS foamed polystyrene board. 3. Polyurethane rigid foams have continuous and compact epidermis and close-cell walls with high strength interconnection of nearly 100%. They have ideal impermeability. The waterproof and thermal insulation layer is continuously seamless by spraying method, forming seamless roof and whole external wall thermal insulation shell, which has excellent waterproof and impermeability. 4. Super self-adhesive property (without any intermediate bonding material), strong bonding with roof and exterior wall, good wind exposure resistance and negative wind pressure resistance; integral spraying construction, completely eliminate "hot spot" and "cold bridge"; flexible gradient technology can effectively prevent cracking of waterproof layer; mechanized operation, automatic proportioning, uniform quality, fast construction, week The period is short.

聚氨酯保溫管是由內(nèi)工作鋼管、發(fā)泡保溫管層及聚乙烯外護管組合而成的保溫管道，隨著聚氨酯保溫管越來越受到熱源輸送工程的青睞，市場上生產(chǎn)聚氨酯直埋保溫管的廠商也越來越多，而聚氨酯直埋保溫管厚度的標(biāo)準(zhǔn)，市場上也是各不相同，那么聚氨酯保溫管厚度的標(biāo)準(zhǔn)到底是多少呢？保溫管廠家?guī)Т蠹伊私庖幌�。只要是大廠、正規(guī)的企業(yè)肯定要生產(chǎn)大于60mm左右厚的聚氨酯保溫管，目前有些不正規(guī)的保溫管廠家一直在拖，或者是生產(chǎn)一部分，或者采購者不懂就做非標(biāo)的，這樣會節(jié)省很多成本，但是生產(chǎn)出來的聚氨酯保溫管質(zhì)量低劣，用于工程中危害很大。60mm左右厚度的標(biāo)準(zhǔn)聚氨酯保溫管與非標(biāo)相比，大大提升了熱源輸送工程的熱源保溫效果與外護管防腐效果，這也只是對于直徑小的保溫管而言，如果需要用到的聚氨酯保溫管直徑大的話還要采用提高厚度才可。

Polyurethane insulating pipe is an insulating pipe composed of inner working steel pipe, foamed insulating pipe layer and polyethylene outer protective pipe. With the increasing popularity of polyurethane insulating pipe in heat source transportation engineering, more and more manufacturers produce polyurethane direct-buried insulating pipe in the market, and the thickness standard of polyurethane direct-buried insulating pipe is in the market. The field is also different, so how much is the thickness of polyurethane insulation pipe? Insulation pipe manufacturers to bring you to know. As long as large factories and regular enterprises are sure to produce polyurethane insulating pipes with a thickness of more than 60 mm, some irregular insulating pipes manufacturers have been dragging, or producing part of them, or purchasers do not know how to make non-standard ones, which will save a lot of costs, but the quality of the polyurethane insulating pipes produced is poor. It is very harmful in engineering. The standard polyurethane insulating pipes with a thickness of about 60 mm are much better than the non-standard ones, which greatly improves the heat preservation effect of heat source conveying engineering and the anti-corrosion effect of external protective pipes. This is only for small diameter insulating pipes, if the diameter of the polyurethane insulating pipes is large, the thickness of the polyurethane insulating pipes should be increased.
