蘭州冷媒劑有哪些性能

蘭州冷媒劑有哪些性能

　　蘭州冷媒劑性能:冷媒劑除了具有防凍性能外(使用溫度為110℃ ~-60℃)，還具有以下優(yōu)點(diǎn):

什么是冷媒劑

什么是冷媒劑

　　冷媒劑是一種無(wú)毒、無(wú)味、無(wú)水分、易腐、無(wú)味的化學(xué)物質(zhì)。長(cháng)期使用對人體和環(huán)境沒(méi)有副作用。因此，在長(cháng)期的回收過(guò)程中，蒸發(fā)損失很小。冷媒劑低損耗，耐寒性強。設備腐蝕性弱，防腐性能完全符合國家標準。長(cháng)期使用不會(huì )對設備造成嚴重的腐蝕損壞。它可以減少閥門(mén)的損失和泄漏，減少管道穿孔和維修?？菇Y垢性強，節能降耗。較少的水垢沉積可以提高冷媒劑的冷卻效果，降低功耗，從而節約能源。

冷媒劑廠(chǎng)家：什么是冷媒劑？泄漏的危害是什么？

冷媒劑廠(chǎng)家：什么是冷媒劑？泄漏的危害是什么？

　　冷媒劑廠(chǎng)家:冷媒劑又名氟利昂，無(wú)毒，但與空氣混合到一定濃度時(shí)會(huì )發(fā)生事故，導致窒息、死亡或嚴重傷害。

冷媒劑廠(chǎng)家：冷媒劑使用方法及特點(diǎn)

冷媒劑廠(chǎng)家：冷媒劑使用方法及特點(diǎn)

冷媒劑廠(chǎng)家：冷媒劑是一種無(wú)毒、無(wú)臭、無(wú)水分、易腐、無(wú)味的化學(xué)物質(zhì)。短期使用不會(huì )對人體和環(huán)境造成副作用。因此，在長(cháng)期的回收過(guò)程中，蒸發(fā)損失很小。冷媒劑低損耗，耐寒性強，對金屬設備腐蝕性弱，其防腐性能完全符合國家標準。長(cháng)期使用不會(huì )對設備造成嚴重的腐蝕損壞。

乙二醇的性質(zhì)的性質(zhì)介紹

乙二醇的性質(zhì)的性質(zhì)介紹

　　乙二醇是一種無(wú)色、無(wú)味、粘稠的液體，熔點(diǎn)為-12.6℃，如果溶于水(60%)，則“水”的冰點(diǎn)會(huì )下降到零下49℃，所以用乙二醇水溶液作為內燃機的冷卻水，可以避免冷卻水結冰帶來(lái)的各種麻煩。即使冷卻水沸騰，乙二醇也不會(huì )蒸發(fā)，因為乙二醇的沸點(diǎn)是197.2℃，至于它的用量，一般可以根據當地的氣候來(lái)確定。

冷媒劑的添加及性能

冷媒劑的添加及性能

　　冷媒劑具有防腐功能，低溫冷凝機組和冷卻系統的材質(zhì)為金屬，包括鐵。碳鋼、銅和其他合金、鋁及其合金、焊料、鋼等。這些金屬在長(cháng)期運行中會(huì )被氧化生成的酸性物質(zhì)乙二醇腐蝕。我公司生產(chǎn)的專(zhuān)用乙二醇冷媒劑添加了雙乙酸生產(chǎn)的添加劑，對金屬腐蝕有效。

冷媒劑的使用方法

冷媒劑的使用方法

　　冷媒劑是一種無(wú)毒、無(wú)味、不含水量、易腐、發(fā)臭的化學(xué)物質(zhì)，長(cháng)期使用不會(huì )對人體和環(huán)境造成副作用。
