2、種與性質(zhì)231. 塑料品種與性質(zhì)241. 塑料品種與性質(zhì)251. 塑料品種與性質(zhì)261. 塑料品種與性質(zhì)271. 塑料品種與性質(zhì)281. 塑料品種與性質(zhì)291. 塑料品種與性質(zhì)301. 塑料品種與性質(zhì)311. 塑料品種與性質(zhì)321. 塑料品種與性質(zhì)331. 塑料品種與性質(zhì)341. 塑料品種與性質(zhì)351. 塑料品種與性質(zhì)361. 塑料品種與性質(zhì)371. 塑料品種與性質(zhì)381. 塑料品種與性質(zhì)391. 塑料品種與性質(zhì)401. 塑料品種與性質(zhì)411. 塑料品種與性質(zhì)塑料杯底下的1，2，3，4，5，6，7。是什么意思？1號(hào) PET 聚對(duì)苯二甲酸乙二醇脂 常見(jiàn)礦泉水瓶、碳酸飲料瓶等 。耐熱至70易變形，

3、 有對(duì)人體有害的物質(zhì)融出。1號(hào)塑料品用了10個(gè)月后，可能釋放出致癌物DEHP。不能放在汽車(chē)內(nèi)曬太陽(yáng)；不要裝酒、油等物質(zhì) 421. 塑料品種與性質(zhì)2號(hào) HDPE高密度聚乙烯 常見(jiàn)白色藥瓶、清潔用品、沐浴產(chǎn)品。不要再用來(lái)做為水杯，或者用來(lái)做儲(chǔ)物容器裝其他物品。清潔不徹底，不要循環(huán)使用。3號(hào) PVC 聚氯乙烯 常見(jiàn)雨衣、建材、塑料膜、塑料盒等?？伤苄詢?yōu)良，價(jià)錢(qián)便宜，故使用很普遍，只能耐熱81.高溫時(shí)容易有不好的物質(zhì)產(chǎn)生,很少被用于食品包裝。難清洗易殘留，不要循環(huán)使用。若裝飲品不要購(gòu)買(mǎi)。 431. 塑料品種與性質(zhì)4號(hào) PE 聚乙烯 常見(jiàn)保鮮膜、塑料膜等 。 高溫時(shí)有有害物質(zhì)產(chǎn)生，有毒物隨食物進(jìn)入人體后

4、，可能引起乳腺癌、新生兒先天缺陷等疾病。 保鮮膜別進(jìn)微波爐。5號(hào) PP 聚丙烯 常見(jiàn)豆?jié){瓶、優(yōu)酪乳瓶、果汁飲料瓶、微波爐餐盒 。熔點(diǎn)高達(dá)167，是唯一可以放進(jìn)微波爐的塑料盒，可在小心清潔后重復(fù)使用。 需要注意，有些微波爐餐盒，盒體以5號(hào)PP制造，但盒蓋卻以1號(hào)PE制造，由于PE不能抵受高溫，故不能與盒體一并放進(jìn)微波爐。 441. 塑料品種與性質(zhì)6號(hào) PS 聚苯乙烯 常見(jiàn)碗裝泡面盒、快餐盒 。不能放進(jìn)微波爐中，以免因溫度過(guò)高而釋出化學(xué)物。裝酸（如柳橙汁）、堿性物質(zhì)后，會(huì)分解出致癌物質(zhì)。避免用快餐盒打包滾燙的食物。別用微波爐煮碗裝方便面。7號(hào) PC其它類(lèi) 常見(jiàn)水壺、太空杯、 奶瓶。百貨公司常用這樣

5、材質(zhì)的水杯當(dāng)贈(zèng)品。很容易釋放出有毒的物質(zhì)雙酚A，對(duì)人體有害。使用時(shí)不要加熱，不要在陽(yáng)光下直曬。 452. 擠出成型462. 擠出成型47DiagramGuild Design is one of aligned company with Microsoft Ltd, and we develop and provide the design templates for Office 97, 2000, and XP.ThemeGallery is a Design Digital Content & Contents mall developed by Guild Design Inc.Tit
