鋼制、銅鋁複合暖氣片的優缺點!

鋼制、銅鋁複合暖氣片的優缺點!

如今，越來越多的家庭開始在家中安裝暖氣片，用以抵禦寒冷。暖氣片的種類有很多，下面就讓聖蒂羅瀾暖氣片小編帶大家來了解一下鋼制、銅鋁複合暖氣片優缺點。

銅鋁複合散熱器比較適合北方的水質及複雜的供暖系統，它最大的優點是耐酸腐蝕，也同時具備輕型暖氣片的一些特點，較適合在獨立供暖系統中與燃氣壁挂爐等獨立供暖設備配合采用。與其它材質的暖氣片相比，銅鋁複合暖氣片要用到相對稀少的銅材料，所以價格相對較貴；另外由于它的特性，造型較單一，外形無法像鋁制暖氣片一樣做成各種藝術造型。

鋼制暖氣片對生産工藝要求比較高，具有金屬強度高、耐壓能力強、外型美觀整潔、安裝維修方便、散熱快，易實現機械化生産等特點。鋼制暖氣片水溫低照常也能散出熱來，是目前市場上應用十分廣泛的暖氣片種類之一，非常適合家庭獨立采暖系統。

Norah brought him over the typed letter. "We walked by the side of our teams or behind the wagons, we slept on the ground at night, we did our own cooking, we washed our knives by sticking them into the ground rapidly a few times, and we washed our plates with sand and wisps of grass. When we stopped, we arranged our wagons in a circle, and thus formed a 'corral,' or yard, where we drove our oxen to yoke them up. And the corral was often very useful as a fort, or camp, for defending ourselves against the Indians. Do you see that little hollow down there?" he asked, pointing to a depression in the ground a short distance to the right of the train. "Well, in that hollow our wagon-train was kept three days and nights by the Indians. Three days and nights they stayed around, and made several attacks. Two of our men were killed and three were wounded by their arrows, and others had narrow escapes. One arrow hit me on the throat, but I was saved by the knot of my neckerchief, and the point only tore the skin a little. Since that time I have always had a fondness for large neckties. I don't know how many of the Indians we killed, as they carried off their dead and wounded, to save them from being scalped. Next to getting the scalps of their enemies, the most important thing with the Indians is to save their own. We had several fights during our journey, but that one was the worst. Once a little party of us were surrounded in a small 'wallow,' and had a tough time to defend ourselves successfully. Luckily for us, the Indians had no fire-arms then, and their bows and arrows were no match for our rifles. Nowadays they are well armed, but there are[Pg 41] not so many of them, and they are not inclined to trouble the railway trains. They used to do a great deal of mischief in the old times, and many a poor fellow has been killed by them." To see the whole of Tokio is a matter of no small moment, as the area of the city is very great. There seems to have been no stint of ground when the place was laid out, and in riding through it you find whole fields and gardens so widely spread that you can readily imagine yourself to be in the rural districts, and are rather surprised when told that you are yet in the city limits. The city is divided into two unequal portions by the Sumida River, and over this river is the Nihon Bashi, or Nihon Bridge, which is often called the centre of Japan, for the reason that all the roads were formerly measured from it. It has the same relation to Japan as the famous "London Stone" has to England, or, rather, as the London Stone had a hundred years ago. "Yes--well--what of him?" As to the manner of cutting out or planing up the lumber for patterns, and the manner of framing them together, it is useless to devote space to the subject here; one hour's practical observation in a pattern-shop, and another hour spent in examining different kinds of patterns, is worth more to the apprentice than a whole volume written to explain how these last-named operations are performed. A pattern, unless finished with paint or opaque varnish, will show the manner in which the wood is disposed in framing the parts together. IV. Do you play golf or hunt or ride horseback or just sit in the sun “She did take the string, as the letter says,” Jeff nodded. “It was a secret—they didn’t broadcast it that the necklace was in the captain’s cabin, locked up in his safe. Nobody knew it, not even the lady’s personal maid, as far as anybody supposed.” He knew the answer to the puzzle of the missing emeralds! “Now we’ll shelve this mystery.” Mr. Everdail led the way to the tender which would transfer them to the yacht for the evening run around illuminated Manhattan. “Eat, and have a good time, Sky Patrol.” Forbes explained their early return, and spoke of the ranch. "It might be a garden, this territory, if[Pg 315] only it had water enough," he said; "it has a future, possibly, but its present is just a little dismal, I think. Are you greatly attached to the life here, Mrs. Cairness?" He was studying her, and she knew it, though his glance swept the outlook comprehensively, and she was watching the mail-carrier riding toward them along the road. It was the brother of the little girl who followed along behind them, and who ran off now to meet him, calling and waving her hand. "Oh, well, if you d?an't choose to tell me ... But I've eyes in my head." "We won't tell him that, though, Davy—we'll make out as it's pure patriotic feeling on our part." "Either you fetch him here or I send fur the police." Calverley made no reply; but, without looking either at Holgrave, or the man who had so fiercely and tauntingly addressed him, took the advantage offered—passed through the door of the foundry, and through the yielding ranks of sneerers and jibers outside; and mounting his horse, galloped rapidly away from the scene of his defeat, with the shout of a hue and cry following his track as far as the foresters considered their legitimate domain.
