1、硬質(zhì)直埋保溫管的導熱系數(shù)并不是那么太高，熱工性能表現(xiàn)穩(wěn)定。當硬質(zhì)直埋保溫管容暮為35～40kg/m3時，導熱系數(shù)僅為0.018g~0.023w/（m.k），約相當于EPS的一半，是目前一切保溫資料中導熱系數(shù)低的。
1. The thermal conductivity of rigid directly buried insulating pipe is not so high, and its thermal performance is stable. When the dusk holding capacity of rigid directly buried insulating pipe is 35-40kg/m3, the thermal conductivity is only 0.018g-0.023w/(m.k), which is about half of the EPS, and is the lowest in all the current thermal insulation data.
2、硬質(zhì)直埋保溫管具有防潮、防水性能。硬質(zhì)直埋保溫管的閉孔率在90％以上，屬于憎水性資料，不會因吸潮增大導熱系數(shù)，墻面也不會滲水。
2. Hard directly buried insulating pipe has moisture-proof and waterproof properties. Hard directly buried insulating pipe has a closed porosity of more than 90%, which is hydrophobic material. It will not increase the thermal conductivity due to moisture absorption, and the wall will not seep.
3、硬質(zhì)直埋保溫管防火，阻燃，耐高溫的優(yōu)勢特性顯露無疑。直埋保溫管在添加阻燃劑后，更是成為一種難燃的自熄性資料，它的軟化點雖然相關(guān)技術(shù)測算可以高達250攝氏度以上，僅在較高溫度時才會呈現(xiàn)合成：另外，直埋保溫管在熄滅時會在其泡沫外表構(gòu)成灰，這層灰有助隔離下面的泡沫。能有效地避免火災蔓延。而且，直埋保溫管在高溫下也不產(chǎn)生有害氣體。
3. Hard directly buried insulating pipe has the advantages of fire-proof, flame-retardant and high temperature resistance. Directly buried thermal insulation pipes, after adding flame retardants, become a kind of inflammable self extinguishing data. Although softening points can be up to 250 degrees Celsius, the softening points can be synthesized only at higher temperatures. In addition, directly buried thermal insulation pipes will form ash on the foam surface when they are extinguished, which will help isolate the foam below. It can effectively avoid the spread of fire. Moreover, direct buried insulating pipes do not produce harmful gases at high temperatures.
4、由于直埋保溫管板材具有優(yōu)良的隔熱性能，在到達同樣保溫請求下，可使減少建筑物外圍護構(gòu)造厚度，從而增加室內(nèi)運用面積。
4. Because of the excellent thermal insulation performance of the directly buried heat preservation tube sheet, the thickness of the building envelope can be reduced and the indoor application area can be increased when the same heat preservation request is reached.
5、抗變形才能強，開裂的不良現(xiàn)象不容易呈現(xiàn)，飾面的終效果十分優(yōu)良。
5. The anti-deformation ability is strong, the bad phenomenon of cracking is not easy to appear, and the final effect of finishing is excellent.
6、直埋保溫管資料孔隙率的構(gòu)造性能穩(wěn)定，由于它根本上采用的是閉孔構(gòu)造，這樣一來保溫性能變得非常好，而且抗凍融、吸聲性效果非普通。硬泡直埋保溫管保溫結(jié)構(gòu)的均勻運用年限，假如沒有什么不測狀況發(fā)作能夠到達30年以上?？梢宰龅皆跇?gòu)造的壽命期正常運用條件下，在枯燥、濕潤或電化腐蝕，以及由于昆蟲、真菌或藻類生長或者由于嚙齒動物的毀壞等外因影響，都不會遭到毀壞。
6. The structure of porosity of directly buried insulating pipe data is stable. Because it basically uses closed-hole structure, the thermal insulation performance becomes very good, and the effect of freeze-thaw resistance and sound absorption is not ordinary. The uniform service life of the rigid foam direct-buried insulation pipe insulation structure can reach more than 30 years if there is no unexpected situation. It can be achieved that the structure will not be destroyed under normal operation conditions, such as dry, wet or electrochemical corrosion, growth of insects, fungi or algae or destruction of rodents.
7、綜合性價比低。固然硬質(zhì)直埋保溫管泡沫材的單價比其它傳統(tǒng)保溫資料的單價高，但增加的費用將會由供暖和制冷費用的大幅度減少而抵消。
7. Low comprehensive price ratio. Although the unit price of rigid and directly buried insulation pipes is higher than that of other traditional insulation materials, the increased cost will be offset by a substantial reduction in heating and cooling costs.
