一次性玉米淀粉餐具這種生物可降解餐具是以玉米、薯類、農(nóng)作物秸稈等可再生資源為原料發(fā)酵生產(chǎn)出來,并進(jìn)一步純化聚合制備成的高純度聚乳酸作為原料生產(chǎn)。下面我們就來簡(jiǎn)單講一講相關(guān)內(nèi)容。
Disposable corn starch tableware this biodegradable tableware is produced by fermenting corn, potato, crop straw and other renewable resources, and further purifying and polymerizing the high-purity polylactic acid as raw material. Now let's talk about the related content briefly.
聚乳酸是可完全生物降解的生物基新材料代表,是目前性價(jià)比較高的生物可降解環(huán)保高分子材料,與傳統(tǒng)的石油基材料相比,每噸聚乳酸可減排約3噸二氧化碳。這是因?yàn)榫廴樗峋哂辛己玫纳锟山到庑?,?jīng)微生物完全降解然后生成二氧化碳和水。相比于普通塑料采用焚燒處理,造成大量溫室氣體排入空氣中,聚乳酸從原材料到聚合物生產(chǎn)過程的碳排放是通用塑料聚乙烯的1/3左右。
Polylactic acid (PLA) is a representative of fully biodegradable new bio based materials. It is a biodegradable environmental friendly polymer material with high cost performance. Compared with traditional petroleum based materials, each ton of PLA can reduce about 3 tons of carbon dioxide. This is because polylactic acid has good biodegradability. It is completely degraded by microorganisms and then generates carbon dioxide and water. Compared with ordinary plastics, which are incinerated, a large number of greenhouse gases are discharged into the air. The carbon emission of polylactic acid from raw materials to polymer production is about 1/3 of that of general plastic polyethylene.
一次性玉米淀粉餐具
一次性玉米淀粉餐具在使用和生物降解過程中不產(chǎn)生有毒有害物質(zhì),具有一定耐菌性、阻燃性和抗紫外線性,可謂健康環(huán)保又。相比常見的可降解塑料,該餐具具有較好的熱穩(wěn)定性、力學(xué)性能,制成塑料袋更加耐用;又有優(yōu)良的生物降解性,在堆肥條件下能夠完全降解為水和二氧化碳,可有效減少白色污染。
Disposable corn starch tableware does not produce toxic and harmful substances in the process of use and biodegradation. It has certain bacteria resistance, flame retardancy and UV resistance. It is healthy, environmental friendly and safe. Compared with common degradable plastics, the tableware has better thermal stability and mechanical properties, and the plastic bag is more durable; It has excellent biodegradability and can be completely degraded into water and carbon dioxide under composting conditions, which can effectively reduce white pollution.
一次性玉米淀粉餐具的優(yōu)點(diǎn):
Advantages of disposable corn starch tableware:
無公害:由于它是玉米淀粉和其他環(huán)保材料精制而成,不含對(duì)人體有害的物質(zhì),可放心長(zhǎng)期使用。
Pollution free: as it is refined from corn starch and other environmental protection materials, it does not contain substances harmful to human body, so it can be safely used for a long time.
零污染:產(chǎn)品埋入泥土中,在適宜的溫度下,90天后可降解形成二氧化碳和水,對(duì)土壤和空氣不造成污染。
Zero pollution: when the product is buried in the soil, it can degrade to form carbon dioxide and water after 90 days at a suitable temperature, without causing pollution to the soil and air.
省資源:玉米淀粉是可再生資源,取之不盡,用之不竭,而紙質(zhì)餐具和塑料餐具需大量的木材和石油化工產(chǎn)品。以玉米淀粉為原料可節(jié)省大量的石油和森林資源。
Provincial resources: corn starch is a renewable resource, which is inexhaustible. Paper tableware and plastic tableware need a lot of wood and petrochemical products. Using corn starch as raw material can save a lot of oil and forest resources.
高品質(zhì):產(chǎn)品密織性好,耐水、耐油、防滲透,同時(shí)具有良好的耐高溫和耐低溫性,適合冰箱冷凍、冷藏、保鮮食品,微波爐加熱等。
High quality: the product has good compactness, water resistance, oil resistance, anti permeability, and good high and low temperature resistance. It is suitable for freezing, cold storage, fresh-keeping food in refrigerator, microwave heating, etc.
此外普通塑料的處理方法依然是焚燒火化,造成大量溫室氣體排入空氣中,而可降解玉米淀粉餐具則是掩埋在土壤里降解,產(chǎn)生的二氧化碳直接進(jìn)入土壤有機(jī)質(zhì)或被植物吸收,不會(huì)排入空氣中,不會(huì)造成溫室效應(yīng)。
In addition, the treatment method of ordinary plastics is still incineration and cremation, resulting in a large number of greenhouse gases discharged into the air, while degradable corn starch tableware is buried in the soil for degradation, and the generated carbon dioxide directly enters the soil organic matter or is absorbed by plants, which will not be discharged into the air and will not cause the greenhouse effect.
