Ukusetshenziswa
I-Dioctyl terephthalate (DOTP) iyi-plasticizer eyinhloko esebenza kahle kakhulu kumapulasitiki e-polyvinyl chloride (PVC). Uma iqhathaniswa ne-diisooctyl phthalate (DOP) esetshenziswa kakhulu, inezinzuzo zokumelana nokushisa, ukumelana nokubanda, ukuguquguquka okunzima, ukulwa nokukhipha, ukuthamba, kanye nezakhiwo ezinhle zokuvikela ugesi. Ibonisa ukuqina okuhle kakhulu, ukumelana namanzi ensipho kanye nokuthamba okuphansi kwemikhiqizo emikhiqizweni. Ngenxa yokuguquguquka kwayo okuphansi, ukusetshenziswa kwe-DOTP kungahlangabezana ngokugcwele nezidingo zezinga lokumelana nokushisa kwezintambo nezintambo, futhi kungasetshenziswa kabanzi ezintweni zekhebula ezimelana nama-degrees angu-70.° C (izinga le-IEC le-International Electrotechnical Commission) kanye neminye imikhiqizo ethambile ye-PVC.
Ngaphezu kwenani elikhulu lama-plasticizer ezinto zekhebula kanye ne-PVC, i-DOTP ingasetshenziswa nasekukhiqizweni kwamafilimu esikhumba sokwenziwa. Ngaphezu kwalokho, i-DOTP inokuncibilika kwesigaba okuhle kakhulu futhi ingasetshenziswa njenge-plasticizers ye-acrylonitrile derivatives, i-polyethylene, i-alcohol butyraldehyde, irabha ye-nitrile, i-nitrocellulose, njll. Ingasetshenziswa futhi njenge-plasticizers yerabha yokwenziwa, izithasiselo zokumboza, izithasiselo zethuluzi elinembile, izithasiselo zokugcoba, kanye nezithambisi zephepha.
Ukupakisha Nokuthumela
Ukupakisha: 250 kg/isigubhu noma ngokwezidingo zamakhasimende.
Ukuthunyelwa: kungokwamakhemikhali avamile futhi kungalethwa ngesitimela, ulwandle kanye nomoya.
Isitoko: sinesitoko sokuphepha esingu-500MTs
Gcina futhi ugcine
Isikhathi sokuphila: Izinyanga ezingama-24 kusukela ngosuku lokwenziwa kwento epakishweni lokuqala elingavulwanga, igcinwe endaweni epholile neyomile kude nokukhanya kwelanga okuqondile, amanzi.
Indawo yokugcina izinto enomoya, Ukomisa okuphansi kwezinga lokushisa, Ihlukaniswe nama-oxidants, ama-acid.
