Botlolo ea Metsi Kereiti ea PET Resin (PET)
Kenyelletso ea Sehlahisoa
Li-chips tsa polyester tsa botlolo ea metsi li loketse ho etsa libotlolo tsa ho paka bakeng sa metsi a hloekileng, metsi a tlhaho a nang le liminerale, metsi a silafalitsoeng, metsi a nooang, lijana tsa tatso le lipompong, botlolo ea litlolo le thepa ea pampiri ea PET jj.
Letšoao la sehlahisoa le na le likarolo tse tlase tsa tšepe e boima, tse tlase tsa acetaldehyde, boleng bo botle ba 'mala, viscosity e tsitsitseng.Ka risepe e ikhethang ea ts'ebetso le theknoloji e tsoetseng pele ea tlhahiso, sehlahisoa se na le likarolo tse ntle tsa ts'ebetso, mocheso o tlase oa ts'ebetso, sebaka se pharaletseng sa ts'ebetso, pepeneneng e ntle haholo le sekhahla sa sehlahisoa se felileng.Ha ho etsoa libotlolo, sehlahisoa se na le ho senyeha ho honyenyane le lintho tse tlaase tsa acetaldehyde.Ha e ntse e netefatsa polokeho le bohloeki, e ka boloka tatso ea metsi a hloekisitsoeng ka ho latellana, metsi a diminerale le metsi a hloekisitsoeng.
