背心袋依然成為人們?nèi)粘Ｉ钪胁豢扇笔У囊患锲妨耍o我們帶來(lái)的方便可謂是**的，**直接的優(yōu)點(diǎn)就是體積小攜帶方便，取代了沉重的籃子。盡管背心袋這么惹人喜愛(ài)，但是你是用的袋子真的安全嗎？ </p> <p> 我們很常見(jiàn)的一種現(xiàn)象就是在街邊的小吃攤前，一些店家在碗里會(huì)套上一層袋子來(lái)盛裝熱食，用完之后就隨手一丟重新套上另一個(gè)，但是這樣真的對(duì)我們的健康安全嗎？怎樣來(lái)區(qū)分背心袋是否0呢？其實(shí)**簡(jiǎn)單的一種方法就是用手觸摸，一般來(lái)說(shuō)***的呈乳白色或透明色，手摸時(shí)有潤(rùn)滑感，外表似蠟樣感； </p><p> 背心袋不要用來(lái)裝一些溫度比較高、油膩的食物.如果當(dāng)時(shí)大家不能一時(shí)間確定自己使用的塑料袋是不是安全的,一選擇就是不能使用其盛裝過(guò)熱或油脂類食品,這一步正是大家將危害降低的方法之一. </p> <p> <br /> </p> <p> 對(duì)背心袋有一定研究的人士曾經(jīng)表明大家如果使用了不安全的塑料袋,則塑料袋內(nèi)部成分中的那些染料、重金屬等物質(zhì)就會(huì)進(jìn)而食物里面，后期大家再進(jìn)食的時(shí)候就會(huì)被帶入大家身體內(nèi)，對(duì)大家身體健康造成傷害.另外大家平時(shí)經(jīng)常會(huì)接觸的油性食品如肉類、魚(yú)類、油條中內(nèi)部成分中的油脂屬于一種溶劑,它能令塑料袋中的有害物質(zhì)析出;而高溫則會(huì)使塑料軟化,同樣能促使有害物質(zhì)析出,

合成樹(shù)脂是塑料的**主要成分，其在塑料中的含量一般在40％～100％。由于含量大，而且樹(shù)脂的性質(zhì)常常決定了塑料的性質(zhì)，所以人們常把樹(shù)脂看成是塑料的同義詞。例如把聚氯乙烯樹(shù)脂與聚氯乙烯塑料、酚醛樹(shù)脂與酚醛塑料混為一談。其實(shí)樹(shù)脂與塑料是兩個(gè)不同的概念。樹(shù)脂是一種未加工的原始聚合物，它不僅用于制造塑料，而且還是涂料、膠粘劑以及合成纖維的原料。而塑料除了極少一部分含100％的樹(shù)脂外，絕大多數(shù)的塑料，除了主要組分樹(shù)脂外，還需要加入其他物質(zhì)。抽繩垃圾袋給我生活帶來(lái)了那些便利？濰坊再生玉米淀粉塑料袋定制</p><p style="text-indent:25px">避免用塑料膜袋長(zhǎng)時(shí)間裝存熱、燙的食物。濰坊再生玉米淀粉塑料袋定制</p><p> 3、增塑劑 </p> <p> 增塑劑可增加塑料的可塑性和柔軟性，降低脆性，使塑料易于加工成型。增塑劑一般是能與樹(shù)脂混溶，***、無(wú)臭，對(duì)光、熱穩(wěn)定的高沸點(diǎn)有機(jī)化合物，**常用的是鄰苯二甲酸酯類。例如生產(chǎn)聚氯乙烯塑料時(shí)，若加入較多的增塑劑便可得到軟質(zhì)聚氯乙烯塑料，若不加或少加增塑劑(用量<10％)，則得硬質(zhì)聚氯乙烯塑料。 </p> <p> 4、穩(wěn)定劑 </p> <p> 為了防止合成樹(shù)脂在加工和使用過(guò)程中受光和熱的作用分解和破壞，延長(zhǎng)使用壽命，要在塑料中加入穩(wěn)定劑。常用的有硬脂酸鹽、環(huán)氧樹(shù)脂等。 </p> <p> 5、著色劑 </p> <p> 著色劑可使塑料具有各種鮮艷、美觀的顏色。常用有機(jī)染料和無(wú)機(jī)顏料作為著色劑。 </p> <p> 6、潤(rùn)滑劑 </p> <p> 潤(rùn)滑劑的作用是防止塑料在成型時(shí)不粘在金屬模具上，同時(shí)可使塑料的表面光滑美觀。常用的潤(rùn)滑劑有硬脂酸及其鈣鎂鹽等。濰坊再生玉米淀粉塑料袋定制</p><p style="text-indent:25px">
