href="http://m.tllngy.com">m.tllngy.com</a> </div> <ul style=" margin:10px 0px;"> </ul> <div id="miyywqe" class="text editor">　　家里的采暖系統也需要使用，采暖系統防凍液具有良好的防凍功能，當環(huán)境溫度低于零度時(shí)，冷卻系統中的水就會(huì )轉變?yōu)楸?，冷卻系統的部件就會(huì )有被膨脹裂損的危險，這時(shí)加入防凍液可以保證設備在零度以下正常工作，那添加的防凍液需要定期更換嗎？<br /> 　　其實(shí)采暖系統防凍液的使用和添加還是有一些需要注意的小細節的。防凍液是液體，雖然工作的環(huán)境相對密封，但時(shí)間長(cháng)了各項性能還是會(huì )發(fā)生變化的。我們知道采暖系統的管路都是金屬的，所以防凍液在生產(chǎn)時(shí)會(huì )加入抗腐蝕的成分，但是隨著(zhù)使用時(shí)間的增長(cháng)抗腐蝕性能會(huì )慢慢減弱，這會(huì )導致管路部件生銹腐蝕終損壞，所以即使防凍和冷卻的能力沒(méi)有降低，我們也要定期更換防凍液。<br /> 　　不過(guò)各類(lèi)防凍液的成分與性能都是不同的，所以更換周期也不一樣，普通的建議兩年左右更換一次，有的采暖系統防凍液更換周期會(huì )很長(cháng)，6年-8年，也有確實(shí)終身免維護更換的防凍液。<br /> 　　以上就是小編與大家分享的采暖系統防凍液是否需要定期更換相關(guān)知識內容了，采暖系統防凍液同樣是需要更換的，但是更換周期會(huì )有差異。另外，添加和更換的時(shí)候千萬(wàn)要選擇與原先一樣類(lèi)型的防凍液，不同類(lèi)型的采暖系統防凍液遇到一起容易發(fā)生化學(xué)反應，會(huì )降低防凍液的性能或是產(chǎn)生結晶，所以不能混加。<br /></div> <div id="emeewec" class="page" style="clear:both;"> 上一條：<a
