何爲生物降解塑料，對環境有何影響

2021/01/12 分類:可降解包裝袋 1583 0

現如今，隨著經濟的快速發展，人們生活水平的不斷提高，對于環境的環保意識也是越來越強。其中對于塑料包裝的改革也是呼聲越來越高，而取而代之的則是生物降解塑料。

那麽什麽是生物降解塑料呢?它對于環保有什麽影響呢?具體如下：

所謂的生物降解塑料是指在自然界和土壤和/或沙土等條件下，和/或特定條件下或厭氧消化條件下或水性培養液中，由自然界存在的最終完全降解變成二氧化碳或/甲烷、水及其所含元素的礦化無機鹽以及新的生物質的塑料。

在實驗期間內(最多180天)，塑料中90%以上的有機碳均已轉化，即證明PSM?生物降解塑料(可堆肥)可完全生物降解(根據EN13432標准第2部分)，降解曲線顯示，90%以上的生物降解塑料僅需80天就成功轉爲二氧化碳、水、能源和生物碳。

生物降解塑料(可堆肥)的可堆肥性能经国际权威的检测机构进行EN13432和ASTMD6400标准检测，并由独立的第三方认证机构DIN CERTCO和VINCOTTE进行认证，取得了”Compostable”标识和“OK Compost”标识。

"But you don't get all the whales you see, by a long shot. Many a whale gets away before you can fasten to him, and many another whale, after you have laid on and fastened, will escape you. He sinks, and tears the iron loose; he runs away to windward ten or twenty miles an hour, and you must cut the line to save your lives; he smashes the boat, and perhaps kills some of his assailants; he dies below the surface, and when he dies there he stays below, and you lose him; and sometimes he shows[Pg 66] such an amount of toughness that he seems to bear a charmed life. We fight him with harpoon and lance, and in these later days they have an invention called the bomb-lance or whaling-gun. A bomb-shell is thrown into him with a gun like a large musket, and it explodes down among his vitals. There's another gun that is fastened to the shaft of a harpoon, and goes off when the whale tightens the line; and there's another that throws a lance half-way through him. Well, there are whales that can stand all these things and live. The reply came slowly. "No; her husband is quite another man; this man's wife has been dead for years. No, Charlotte Oliver lives in--hark!" "Since the hour of her marriage she has never gone into her chamber without locking the door; she has never come out of it unarmed." The only purpose of my publication was to convince everybody of this, and thereby prevent the repetition of such a scandalous scene. An interpreter translated to the accused the questions put by the judge, who understood the replies, though he was not allowed to speak excepting in English. Dick, examining with the thoroughness of an expert, with Jeff’s and his chum’s life perhaps depending on his care, stated that he saw no damage to the waterproofed coverings of the water supports. Declaring that they would stand by and watch the airplane, Sandy and Dick watched Larry and Jeff get settled, Dick spun the propeller to pump gas into the still heated cylinders, Jeff gave the “switch-on—contact!” call, Dick, pulling down on the “prop,” sprang aside to avoid its flailing blades, and the amphibian’s engine took up its roar. He transmitted the suggestion. Almost as his hand touched the cable and twitched at it, his other hand, as he lay with his weight on his chin, face and chest, contacted something else—a large, roundish object, feeling like a spare landing wheel tire. It was short and to the point upon Cairness's part, and having finished he stood up. "I don't believe a word of hit," said the woman, who yet showed that she was touched by the allusion to the Baptist Church, as the Deacon had calculated, for most of the people of that section professed to be of that denomination. "What'll yo' gi' me for them chickens?" HoME 学生妹被老师 ENTER NUMBET 001001313.com.cn
