ISBM in\u017eenjering su\u0161enja smole:
\nVodi\u010d za korejsku produkciju<\/h1>\n

Neadekvatno su\u0161enje smole je uzrok ve\u0107eg broja nedostataka u korejskim ISBM-ima - tragovi \u0161irenja, gubitak IV vrijednosti, stvaranje acetaldehida, zamu\u0107enje predoblika - nego bilo koji pojedina\u010dni parametar procesa osim temperature kondicioniranja. Fizika vlage u PET-u, PETG-u i Tritanu na temperaturama ISBM cijevi zahtijeva sistematsku kontrolu su\u0161enja koju ve\u0107ina korejskih proizvodnih operacija tretira kao pozadinsku korisnost, a ne kao precizni korak u procesu.<\/p>\n

Sva vremena su\u0161enja pretpostavljaju pravilno dimenzioniranu su\u0161ilicu s lijevkom za odvla\u017eivanje na navedenoj temperaturi i ta\u010dki rose. Su\u0161a\u010di vru\u0107im zrakom (bez sredstva za su\u0161enje) ne mogu pouzdano posti\u0107i ciljeve vla\u017enosti za PET i Tritan u korejskim ljetnim uvjetima - su\u0161ilice s odvla\u017eivanjem su obavezne za poliesterske smole.<\/p>\n<\/div>\n
