2.看烧起来的部分,如果过分发黑或者油滴的很快,多数熔点不正常,这在PET薄膜片中常有。
3.拉丝,烧着的时候在打火机上拉一下丝,看丝拉的长不长,然后把拉出来的丝拉断,看中间的断点,丝是不是卷成小圈状,卷的越多说明熔点高。
七、PET是安全的吗?
PET已安全通过美国FDA、加拿大卫生部、欧洲食品安全局和世界上几乎所有其他的健康安全机构认证。数十年间,它已被用于食品和饮料容器没有任何已知的不利影响。PET和PET包装的广泛的研究一再表明它是安全的。
八、PET瓶和容器可以被回收吗?
PET瓶是目前可回收性较高的塑料包材,可回收。
根据联合国环境规划署,在所有包装商品和零售部门签署机构中,饮料部门的可回收包装占塑料包装总重量比例达88%,可回收性远超其他部门的塑料包装。这得益于PET材质在饮品包材中的普遍应用。
从全球PET瓶的回收率看,部分国家的PET瓶回收情况差距较大,中国94%的回收率居位置,这受益于中国具有一套以经济利益驱动、适应本国国情的高效率PET瓶回收体系,充分展现了它的灵活性和独特性
九、PET是如何被回收的?
PET塑料的循环过程一般分为脱标(脱标机去除标签纸),破碎(破碎机破碎),筛选(将不同类别的塑料瓶子进行分选),清洗(预清洗和漂洗机进行清洗),干燥(PET瓶片脱水机,管道干燥等设备进行干燥),造粒(运用PET瓶片造粒机进行造粒)。
Xa kufika kwindawo ezitshiswayo, ukuba zibe mnyama kakhulu okanye iidroplets ze-oyile ngokukhawuleza, amaninzi eendawo ezitshisa azi, ezi kwisheti zefilm ze-PET.
3. Umzobo wocingo: Xa utshiswa, tsala ucingo kumkhanyisi ukuze ubone ukuba ubude, kwaye emva koko uphule ucingo olutsaliweyo ukuze ubone ukuba indawo yokuphuma phakathi igqunywea ezincinci. Xa kukho iintsontelo ezininzi, aphezulu kwentsika.
7, Ingaba PET ikhuselekile?
PET has been safely certified by the US FDA, Health Canada, European Food Safety Agency, and almost all other health and safety agencies around the world. Kwiminyaka esetyenziswa kwizikhongozeli zokudla neziselo ngaphandle kweziphumo ezibalulekileyo ezaziwayo. Uhlobo olukhulu lwePET kunye nokufakwa kwePET lubonise ngokuphinda ukuba ikhuselekile.
8, Ingaba iibhotshi ze PET nezikhongozeli zingasebenziswa kwakhona?
Ibhotshi ze-PET ngoku zizixhobo zokuphawula kweplastiki ezinokusebenzisa kwakhona.
Ngokwenkqubo yoLuntu lweNhlangano lweNtshona Koloni, ukufakwa kwakhona okufakwa kwakhona kwicandelo lokusela okuquka ubunzima obupheleleyo bomthwalo weplastiki phakathi kwezonke iimpahla zokuphawula kunye neeagenti zokuphawula ezitshintshiweyo ezingaphezulu kakhulu kunokufakwa kweplastiki kwezinye iicandelo. Oku kungenxa yokusetyenziswa okukhulu kwempahla ye-PET kwimpahla yokufaka ukususa.
Kusukela kwimboniso yebhotshi yePET yehlabathi, kukho isithuba esibalulekileyo kwimeko yokuphindwa kwebhotshi yePET kumazwe amanye, kunye neTshayina iqela kuqala ngesantya sokuphinda ukusebenzisa kwakhona kwe94%. Oku kungenxa yenkqubo yokuphindwa kwebhotshi yePET esebenzayo yaseTshayina esi yintliziyo zo kwaye ilungiselwe kwimeko zayo zezizwe, ibonisa ngokupheleleyo ubunzi
9, Uyanikwa njani i-PET?
Inkqubo yokujikeleza kweplastiki ye-PET i yahlulwe kwi-labeling (iphepha elibhaliweyo lususwa ngomatshini we-de labeling), ukujikeleza (ukujikeleza), ukujikeleza (ukuhlela uhlobo oluhlukeneyo lwebhodi ezibhaliweyo ze-plastic), ukuhlambulula (ukucoca ngaphambi kokuqala kwakunye nokucoca umashini wokuqala), ukuwoma (umashini wokutsala kwebhodi ye-PET, ukuwoma kombhodi kunye nezinye izixhobo zokusoma), kunye nokukhusela
