氣泡袋是環(huán)?？山到馀菽芰希?/h5> 發(fā)布于：2019/11/12 　　氣泡袋是一種生物可降解泡沫塑料在光降解塑料、當(dāng)前在聚羥基丁酸酯(PHB)和聚羥基戊酸酯(PHV)討論,其功能類似于PE和PP, PE的是大約10倍,其真相是聚合物接收紫外線效果,削弱的關(guān)鍵,長(zhǎng)鏈片段分為低分子量、身體功能下降。較低分子量的碎片在空氣中進(jìn)一步氧化，導(dǎo)致自由基鏈斷裂，進(jìn)一步降解為CO2和水。

　　The bubble bag is a kind of biodegradable foam plastic. It is discussed in terms of photodegradable plastics, currently in polyhydroxybutyrate (PHB) and polyhydroxyvalerate (PHV), its function is similar to PE and PP, and the price of PE is about 10 times. The truth is that the polymer receives ultraviolet effect, weakens the key, and the long chain fragment is divided into low molecular weight and decreased body function. The fragments with lower molecular weight were further oxidized in the air, resulting in the fracture of free radical chain and further degradation to CO2 and water.

　　根據(jù)降解機(jī)理，可降解塑料可分為光降解塑料、光敏劑光降解塑料、生物降解塑料和多功能可降解塑料。根據(jù)降解塑料的情況，分為光降解塑料、生物降解塑料、完全生物降解塑料、部分生物降解塑料、氧化降解塑料、水降解塑料和由三種降解塑料組成的復(fù)合降解材料。

　　According to the degradation mechanism, degradable plastics can be divided into photodegradable plastics, photosensitizer photodegradable plastics, biodegradable plastics and multifunctional degradable plastics. According to the situation of degradable plastics, it can be divided into photodegradable plastics, biodegradable plastics, fully biodegradable plastics, partially biodegradable plastics, oxidative degradable plastics, water degradable plastics and composite degradable materials composed of three kinds of degradable plastics.

　　添加光敏劑的光降解塑料是塑料加工過程中的幾種光敏劑。由于光敏劑的光激發(fā)效應(yīng)和光化學(xué)反應(yīng)，會(huì)產(chǎn)生自由基激發(fā)源，所以氣泡袋材料可以加速聚合物的光降解過程。這種塑料制造方法簡(jiǎn)單，成本也低。光降解塑料只有在陽(yáng)光照射的條件下才能降解，受地理和天氣條件的限制。

　　Photodegradable plastics with photosensitizers are several photosensitizers in the process of plastic processing. Due to the photo excitation effect and photochemical reaction of photosensitizer, free radical excitation source will be generated, so the bubble bag material can accelerate the photodegradation process of polymer. This kind of plastic is easy to manufacture and low in cost. Photodegradable plastics can only be degraded under the condition of sunlight, which is limited by geographical and weather conditions.

　　泡袋，又稱氣墊膜、珠塑料、泡圈等，采用低密度聚乙烯加工而成，是一種用途廣泛、用途明確的軟包裝材料，用途廣泛。氣泡袋原理是由包括氣泡在內(nèi)的薄膜構(gòu)成，以避免產(chǎn)品受到?jīng)_擊，保證產(chǎn)品在震動(dòng)時(shí)的保養(yǎng)效果，同時(shí)還具有保溫效果，適用于不同行業(yè)的產(chǎn)品包裝或周轉(zhuǎn)。因?yàn)闅馀荽膶邮浅錆M空氣的，所以車身輕、有彈性、隔音、防震、抗磨損的功能，而且還具有防水、防潮、抗壓、減少阻力等功能。

　　Bubble bag, also known as air cushion film, bead plastic, bubble ring, etc., is made of low-density polyethylene. It is a kind of flexible packaging material with wide use and clear use. The principle of bubble bag is composed of film including bubble, so as to avoid the impact of the product, ensure the maintenance effect of the product when it vibrates, and also have the effect of heat preservation, which is applicable to the packaging or turnover of products in different industries. Because the central layer of the bubble bag is full of air, the body is light, elastic, sound proof, shockproof and wear-resistant, and it also has the functions of water-proof, moisture-proof, compression resistance and resistance reduction.
