塑料袋的原料系高分子化合物,其結(jié)構(gòu)穩(wěn)定,不易被天然微生物菌降解,不可降解的塑料袋自然腐爛需要200年以上。廢塑料袋如不回收,混在土地中,而造成土壤板結(jié),影響農(nóng)作物吸收養(yǎng)分和水分,導致農(nóng)作物減產(chǎn)。定制塑料袋嚴重污染環(huán)境衛(wèi)生,增加環(huán)衛(wèi)工人的工作量。每天大風天氣,塑料袋刮得滿天飛舞,有的掛在樹梢上,有的掛在電線上,起來費時費力又危險。如果將它隨意焚燒,會散發(fā)有毒氣體,污染空氣,影響人們健康。塑料袋一,在塑料袋中含有一種能夠致癌的物質(zhì),這種致癌的物質(zhì)叫做苯并芘,這個物質(zhì)具有很強的致癌性,如果經(jīng)常去使用塑料袋來裝食物塑料袋中所含有的致癌物質(zhì)就會慢慢的釋放出來,進入到我們的食物當中,人體進食的過程中會導致我們?nèi)梭w的細胞發(fā)生癌變。
The raw materials of plastic bags are polymer compounds, which have stable structure and are not easy to be degraded by natural microorganisms. It takes more than 200 years for non degradable plastic bags to decay naturally. If the waste plastic bags are not recycled, they will be mixed in the land, causing soil hardening, affecting the absorption of nutrients and water by crops, resulting in crop yield reduction. Customized plastic bags seriously pollute the environment and sanitation, increasing the workload of sanitation workers. In windy weather every day, plastic bags are flying all over the sky. Some of them are hung on tree tops and some on electric wires. It is time-consuming, laborious and dangerous to clear them. If it is burned at will, it will emit toxic gas, pollute the air and affect people's health. Plastic bag 1 contains a carcinogenic substance, which is called benzopyrene. This substance has a strong carcinogenicity. If plastic bags are often used to contain food, the carcinogenic substances contained in plastic bags will slowly release and enter our food. When people eat, our cells will become cancerous.
二、當然,大家在選擇這一些塑料袋的時候,除了應該要去關(guān)注他的,抗拉性究竟好不好之外,還應該要去關(guān)注我們的袋子的原料是否是的?塑料袋因為有一些袋子的制作原料非常的差由這一些劣質(zhì)的原料生產(chǎn)出來的背心袋會有非常重的異味,不僅僅不能夠用它來裝一些食物,甚我們用它來裝一些普通的商品,其實也會給這些商品帶來比較大的傷害。塑料袋加工當然,我們?nèi)绻麑⑦@些袋子拿來當做垃圾袋,也并不是非常的,雖說像這種味道比較重的袋子,大家千萬不能夠拿它用來包裝食物,因此大家在采購這些背心袋的時候一定要要求廠家使用那些全新的原料來進行生產(chǎn),不然的話,我們的這些背心袋可能就會帶來更多的負面的影響。
2、 Of course, when choosing these plastic bags, we should pay attention to whether the raw materials of our bags are safe in addition to their tensile properties? Because some bags are made of very poor materials, the vest bags made of these inferior materials will have a very heavy odor. Not only can they not be used to hold some food, but even we can use them to hold some ordinary goods. In fact, it will also cause great harm to these goods. Of course, plastic bag processing is not very safe if we use these bags as garbage bags. Although such bags with heavy taste cannot be used to package food, when purchasing these vest bags, we must require manufacturers to use those new raw materials for production. Otherwise, our vest bags may bring more negative effects.
1、油墨調(diào)配小技巧缺什么色相加什么色相的油墨。去除某色相中偏多的色相時,應正確應用互為補色的原理。乳山塑料袋在生產(chǎn)實踐中,有時為了使白色更白,在白墨中加微量的群青(百分之1左右),用來白色中的黃色就可達到目的。塑料袋而只要在黑墨中加入少量的鈦青藍,就可黑墨中的黃色調(diào)。制淡色油墨時,要在白墨中加入色墨,而不要把白墨加入色墨中,白墨的遮蓋力特強,加入過多會很快沖淡顏色。而在配制深色油墨時,則一定要把黑墨添加入色墨中,切不可把色墨添加入黑墨中,因為黑墨的著色力特強,稍不慎而加入過多,就需要加入相當多的色墨來調(diào)整顏色。觀察色樣時,盡量在標準光源下進行,且要采用相同的底板。
1. Ink dispensing tips What hue is missing and what hue is added to the ink. The principle of complementary colors should be correctly applied when removing more colors in a color phase. In the production practice of Rushan plastic bags, sometimes in order to make the white more white, a small amount of ultramarine blue (about 1%) is added to the white ink to eliminate the yellow in the white. As long as a small amount of titanium blue is added to the black ink, the yellow tone in the black ink can be eliminated. When making light colored ink, you should add colored ink to white ink instead of white ink. White ink has strong hiding power and will dilute the color quickly if you add too much. When preparing dark ink, black ink must be added to the color ink, and color ink must not be added to the black ink. Because black ink has strong coloring power, it is necessary to add a considerable amount of color ink to adjust the color. Observe the color sample under the standard light source as much as possible, and use the same base plate.
