PET Neden Kurutulmal\u0131d\u0131r?<\/h5>\n\n\n\n

\u2022 Hidrolitik bozulmay\u0131 \u00f6nler: Y\u00fcksek s\u0131cakl\u0131kta i\u015flenen nemli PET, hidrolize
u\u011frayarak molek\u00fcler yap\u0131s\u0131n\u0131 kaybeder. Bu, \u00fcr\u00fcn kalitesinin d\u00fc\u015fmesine yol a\u00e7ar.
\u2022 \u015eeffafl\u0131k ve mukavemeti korur: Kurutulmam\u0131\u015f PET ile \u00fcretilen \u015fi\u015feler veya
levhalar bulan\u0131k olabilir ve mekanik dayan\u0131m\u0131 d\u00fc\u015f\u00fck olur.
\u2022 Kal\u0131plama hatalar\u0131n\u0131 \u00f6nler: PET\u2019in i\u00e7inde nem kald\u0131\u011f\u0131nda \u00fcretim
s\u0131ras\u0131nda hava kabarc\u0131klar\u0131, renk de\u011fi\u015fimleri veya y\u00fczeyde p\u00fcr\u00fczlenmeler g\u00f6r\u00fclebilir.<\/p>\n\n\n\n

PET Kurutma Nas\u0131l Yap\u0131l\u0131r?<\/h5>\n\n\n\n
    \n
  1. Kurutucu Kullan\u0131m\u0131: PET gran\u00fclleri, kurutucu hopper denilen
    sistemlere yerle\u015ftirilerek 160-180\u00b0C\u2019de 4-6 saat boyunca kurutulur.<\/li>\n\n\n\n
  2. D\u00fc\u015f\u00fck Nemli Hava ile Kurutma: Kurutma i\u015flemi s\u0131ras\u0131nda s\u0131cak ve
    d\u00fc\u015f\u00fck nemli hava kullan\u0131larak malzemenin i\u00e7indeki nemin d\u0131\u015far\u0131 at\u0131lmas\u0131 sa\u011flan\u0131r.<\/li>\n\n\n\n

    s\u0131cakl\u0131kta nemi \u00e7eker ve enerji tasarrufu sa\u011flar.<\/li>\n\n\n\n
  4. Kristalizasyon ve Kurutma: Geri d\u00f6n\u00fc\u015ft\u00fcr\u00fclm\u00fc\u015f PET (rPET) i\u00e7in
    \u00f6nce kristalizasyon i\u015flemi uygulan\u0131r, ard\u0131ndan kurutulur.<\/li>\n<\/ol>\n\n\n\n

    PET i\u015fleme \u00f6ncesi do\u011fru \u015fekilde kurutulmazsa \u00fcr\u00fcn\u00fcn kalitesi d\u00fc\u015febilir, mekanik
    dayan\u0131kl\u0131l\u0131\u011f\u0131 azalabilir ve \u00fcretim s\u0131ras\u0131nda istenmeyen hatalar olu\u015fabilir. Bu y\u00fczden
    PET \u00fcretiminde kurutma i\u015flemi kritik bir ad\u0131md\u0131r.<\/p>\n\n\n\n

    2. Is\u0131tma ve Nem Uzakla\u015ft\u0131rma<\/strong>
      \u2022 PET gran\u00fclleri, 160-180\u00b0C s\u0131cakl\u0131k aral\u0131\u011f\u0131nda 4-6 saat boyunca kurutulur.
      \u2022 Bu s\u00fcre\u00e7te s\u0131cak, d\u00fc\u015f\u00fck nemli hava s\u00fcrekli olarak malzemenin i\u00e7inden

    3. Nem Kontrol\u00fc ve S\u00fcrekli Kurutma
      <\/strong>\u2022 Kurutma s\u0131ras\u0131nda nem seviyesi 50 ppm\u2019in (parts per million) alt\u0131na
      d\u00fc\u015fene kadar i\u015flem devam eder.
      \u2022 Baz\u0131 sistemlerde vakum kurutma y\u00f6ntemi kullan\u0131larak daha d\u00fc\u015f\u00fck
      s\u0131cakl\u0131klarda enerji tasarruflu bir kurutma sa\u011flan\u0131r.<\/li>\n\n\n\n
    4. Kurutulmu\u015f PET\u2019in \u0130\u015fleme Haz\u0131rlanmas\u0131
      <\/strong>\u2022 Nemden ar\u0131nd\u0131r\u0131lm\u0131\u015f PET, hemen i\u015flenmezse tekrar nem \u00e7ekmemesi i\u00e7in
