PVC塑料通風管的注意事项

PVC塑料通風管的注意事项

1.PVC塑料通風管用專用膠水連接，使用前必須搖勻。

2.PVC塑料通風管和插座必须清洁。槽与槽之间的间隙越小，越容易用砂布或锯片打磨连接面。在槽上均匀地涂一薄层胶水。在插座外面涂两次胶水。胶水干透40-60秒后，插入到位。同时，根据气候变化增加或减少胶水的干燥时间。

3.粘接時禁止接觸水。管道就位後，必須將其放入凹槽中。接縫幹燥24小時後，應開始回填。回填時，管道應填砂密實，並預留接縫，以便***規模回填。

4.当PVC塑料通風管和钢管套在一起时，钢管接头必须清洁并粘合。PVC塑料通風管加热软化(但不烧坏)后，套在钢管上冷却。

[Pg 86] There was the man who twice within the last hour had been in danger of his life chatting quietly with the man who had robbed him. The two were evidently on the best of terms, for Maitrank was laughing heartily, and Balmayne stood opposite smoking a cigarette like a host who speeds a parting guest. 225 As soon as we returned to Palitana the Rajah sent to inquire after me, and to present me with round boxes of fruit preserved in Cashmere, oval green grapes, each wrapped separately in cotton and smelling of honey. Dick echoed the cry. Jeff had already caught the threat of that swamp below them. They could not risk going a foot lower. The pilot opened his throttle, picking up climbing speed to the roar of his engine. “It’s a kind of sense that’s common enough—but——” “Why didn’t you tell me?” her cousin demanded. They all saw the captain’s face assume an expression of disgust. CHAPTER XXX DICK ENCOUNTERS THE “GHOST” They came around him and offered him their horses, dismounting even, and forcing the reins into his hands. "You don't know what you are doing," a corporal urged. "You'll never get out alive. If it ain't Indians, it'll be thirst." Then he looked into Cabot's face and saw that he did know, that he knew very well. And so they left him at last, with more of the tepid alkali water than they well could spare from their canteens, with two days' rations and an extra cartridge belt, and trotted on once more across the plain. Shorty had dropped on to a bench, and fixed his eyes on the stone wall opposite, as if desperately striving to read there some hint of extrication from his perplexities. The thought of encountering Maria's bright eyes, and seeing there even more than her sharp tongue would express, numbed his heart. "And will you do that alone?" With Richard things were different. He despised Reuben as bestial, and sometimes jeopardised his skin by nearly showing his contempt. He now had a peculiar friendship with Anne Bardon. They had met accidentally a second time, and deliberately half a dozen more. In Richard Anne had made a discovery—he appealed to her imagination, which ran on severe lines. She sympathised with his ambition to break free from the grind and grossness of Odiam, and resolved to help him as much as she could. She lent him books, and guided him with her superior knowledge and education. "The same, your grace, if my judgment be correct." At this moment a messenger rode up to Oakley, and, putting a letter into his hands, instantly retired. HoME 午夜伦理av男人的天堂wwww6080comENTER NUMBET 008yepme.com.cn
