G\u00fcnl\u00fck hayat\u0131m\u0131zda yayg\u0131n olarak kullan\u0131lan bilmedi\u011fimiz bir\u00e7ok malzeme var. \u00d6rne\u011fin, PP malzemesi, baz\u0131 su bardaklar\u0131 \/ su \u015fi\u015feleri ve taze tutma kutular\u0131 PP malzemeden yap\u0131lm\u0131\u015ft\u0131r. PP malzemesi nedir? \u015eimdi tan\u0131yal\u0131m.<\/p>\n
<\/p>\n
PP malzemeye polipropilen denir, s\u0131cakl\u0131k dayan\u0131m\u0131 \u2013 20 \u2013 120 derece aras\u0131nda olan, mikrodalga f\u0131r\u0131nlar i\u00e7in en yayg\u0131n kullan\u0131lan \u00f6zel plastiklerden biridir.<\/p>\n

Yayg\u0131n eski moda g\u00fcnl\u00fck terliklerimizin baz\u0131lar\u0131 PVC'den yap\u0131l\u0131r. Yaz\u0131n yumu\u015fak, k\u0131\u015f\u0131n serttirler, bu da PVC'nin s\u0131cakl\u0131k hassasiyetiyle yak\u0131ndan ili\u015fkilidir. Y\u00fcksek s\u0131cakl\u0131klarda PVC, zehirli bir gaz olan kloru ayr\u0131\u015ft\u0131r\u0131r. Bunlar aras\u0131nda PVC'nin yo\u011funlu\u011fu en y\u00fcksek olan\u0131d\u0131r.<\/p>\n

G\u00fcnl\u00fck ihtiya\u00e7lar i\u00e7in kullan\u0131lan yayg\u0131n plastik torbalar, iyi toklu\u011fa sahip PE'den yap\u0131l\u0131r. PE ayr\u0131ca HDPE (y\u00fcksek yo\u011funluklu polietilen) ve LDPE (d\u00fc\u015f\u00fck yo\u011funluklu polietilen) olarak da ayr\u0131labilir. Farkl\u0131 yo\u011funluklar, PE'nin farkl\u0131 \u00f6zelliklerine yol a\u00e7ar.<\/p>\n

PP malzemesi g\u00fcnl\u00fck ihtiya\u00e7 malzemelerinin plastikleri aras\u0131nda nispeten g\u00fcvenli bir plastiktir. Genellikle g\u0131da ambalaj po\u015fetleri bundan yap\u0131l\u0131r. Elbette PP'nin de dereceleri vard\u0131r. G\u0131da ambalajlar\u0131 g\u0131da s\u0131n\u0131f\u0131nda olmal\u0131d\u0131r.<\/p>\n
<\/p>\n
Bu makromolek\u00fcl malzemeler genellikle ba\u015fka malzemeler eklenerek modifiye edilebilir, b\u00f6ylece genel performanslar\u0131 veya performanslar\u0131 bir a\u00e7\u0131dan \u00fcst\u00fcn olur ve \u00f6zel ama\u00e7lar i\u00e7in kullan\u0131labilirler. Elbette, modifiye edilmi\u015f malzemelerin fiyat\u0131 bazen b\u00fcy\u00fck \u00f6l\u00e7\u00fcde artacakt\u0131r.<\/p>\n

Genel plastikler s\u0131cak yiyeceklerle do\u011frudan temas edemez. PP malzeme kullan\u0131ld\u0131\u011f\u0131nda bu sorun hakk\u0131nda endi\u015felenmenize gerek yoktur. Nitelikli PP malzeme mikrodalga f\u0131r\u0131nda kullan\u0131labilir.<\/p>\n
