Ukusetyenziswa
I-Dioctyl terephthalate (DOTP) yeyona plasticizer iphambili esebenza kakuhle kakhulu kwiiplastiki ze-polyvinyl chloride (PVC). Xa ithelekiswa ne-diisooctyl phthalate (DOP) esetyenziswa kakhulu, ineengenelo zokuxhathisa ubushushu, ukumelana nokubanda, ukuguquguquka okunzima, ukulwa nokukhupha, ukuthamba, kunye neempawu ezilungileyo zokugquma umbane. Ibonisa ukuqina okugqwesileyo, ukumelana namanzi esepha kunye nokuthamba okuphantsi kobushushu kwiimveliso. Ngenxa yokungazinzi kwayo okuphantsi, ukusetyenziswa kwe-DOTP kunokuhlangabezana ngokupheleleyo neemfuno zokumelana nobushushu beentambo kunye neentambo, kwaye ingasetyenziswa kakhulu kwizinto zekhebula ezimelana nama-70 degrees.° C (umgangatho we-IEC weKhomishini ye-Electrotechnical yeHlabathi) kunye nezinye iimveliso ezithambileyo zePVC.
Ukongeza kwinani elikhulu leeplastiki ezisetyenziselwa izinto zekhebula kunye nePVC, iDOTP ingasetyenziswa nakwimveliso yeefilimu zesikhumba ezenziweyo. Ukongeza, iDOTP inokunyibilika kakuhle kwinqanaba kwaye ingasetyenziswa njengeeplastiki ezisetyenziselwa izinto eziphuma kwi-acrylonitrile, i-polyethylene, i-alcohol butyraldehyde, irabha ye-nitrile, i-nitrocellulose, njl. Ingasetyenziswa njengeeplastiki zerabha ezenziweyo, izongezo zokugquma, ii-lubricant zezixhobo ezichanekileyo, izongezo zokugquma, kunye nezithambisi zephepha.
Ukupakishwa kunye nokuthunyelwa
Ukupakisha: 250 kg/idrama okanye ngokweemfuno zabathengi.
Ukuthunyelwa: kungokweekhemikhali eziqhelekileyo kwaye kungathunyelwa ngololiwe, ulwandle nomoya.
Isitokhwe: sinesitokhwe sokhuseleko se-500MTs
Gcina kwaye ugcine
Ixesha lokuphelelwa: Iinyanga ezingama-24 ukususela kumhla wokwenziwa kwayo kwiphakheji yokuqala engavulwanga igcinwe kwindawo epholileyo neyomileyo kude nelanga elithe ngqo, amanzi.
Indawo yokugcina umoya, Ukomisa kubushushu obuphantsi, Yahlulwe kwii-oxidants, ii-asidi.
