Isingeniso Esifushane ku-DOP kanye ne-DOTP

Ukwethulwa kwe-DOP ne-DOTP

Ukubuka konke

Abanye abantu bangase babuze ukuthi iyini i-DOP nokuthi iyini i-DOTP. Ingabe banomehluko? Ziyini izinzuzo zabo kanye nokungalungi kwabo? Vumela uHuisu Qinye akutshele ukuthi iyini i-DOP kanye ne-DOTP. Futhi, sizokwenza wazi kangcono ngomehluko phakathi kwe-DOP kanye ne-DOTP.

I-Dioctyl phthalate ibizwa ngokuthi i-dioctyl ester (DOP) - i-organic ester compound kanye ne-plasticizer esetshenziswa kakhulu. I-Dioctyl phthalate iyi-plasticizer ebalulekile yenhloso ejwayelekile. Isetshenziswa kakhulu ekucubungulweni kwe-polyvinyl chloride resin, futhi ingasetshenziswa nasekucubungulweni kwama-polymer aphezulu njenge-chemical fiber resin, i-acetic acid resin, i-ABS resin, kanye nerabha. Upende, udayi, ama-dispersants, njll.

I-DOP yenhloso ejwayelekile: isetshenziswa kabanzi kumapulasitiki, irabha, upende, ama-emulsifier, kanye neminye imboni. I-PVC eyenziwe ngepulasitiki ingasetshenziswa ukukhiqiza isikhumba sokwenziwa, amafilimu ezolimo, izinto zokupakisha, izintambo, njll.

I-Electrical DOP: Ngaphezu kwazo zonke izakhiwo ze-DOP yenhloso ejwayelekile, iphinde ibe nezakhiwo ezinhle zokuvikela ugesi, ezisetshenziswa kakhulu ekukhiqizeni izintambo nogesi.

I-DOP yezinga lokudla: isetshenziswa kakhulu ekukhiqizweni kwezinto zokupakisha ukudla.

I-DOP yezinga lezokwelapha: isetshenziselwa kakhulu ukukhiqizwa kwemikhiqizo yezokwelapha neyezempilo, njengemishini yezokwelapha elahlwayo kanye nezinto zokupakisha zezokwelapha.

I-DOTP

I-DOTP plasticizer ingenye uhlobo lwe-plasticizer, lo mkhiqizo uketshezi olucishe lungabi nombala olune-viscosity ephansi. I-Viscosity 63mPa.s (25°C), 5mPa.s (100°C), 410mPa.s (0°C). Iphuzu lokubanda -48°C. Iphuzu lokubila lingu-383°C (0.1)MPa.s (0°C). Iphuzu lokubasa lingu-399°C. Igama lesayensi: i-dioctyl terephthalate. Ngokuvamile, sasiyibiza ngokuthi i-DOTP.

Ngaphezu kwenani elikhulu lama-plasticizer asetshenziswa ezintweni zekhebula kanye ne-PVC, i-DOTP ingasetshenziswa nasekukhiqizweni kwamafilimu esikhumba okwenziwa. Ngaphezu kwalokho, ihambisana kahle kakhulu futhi ingasetshenziswa njenge-plasticizer yezinto ezitholakala ku-acrylonitrile, i-polyvinyl butyral, irabha ye-nitrile, i-nitrocellulose, njll.

1. Izinzuzo ezahlukene ze-DOP ne-DOTP

Uma kuqhathaniswa ne-dioctyl phthalate (DOP) esetshenziswa kakhulu, i-dioctyl terephthalate (DOTP) inezinzuzo zokumelana nokushisa, ukumelana nokubanda, ukungaguquguquki, ukulwa nokukhipha, ukuguquguquka, kanye nezakhiwo ezinhle zokuvikela ugesi. Ukuqina okuhle kakhulu, ukumelana namanzi anensipho, kanye nokuthamba okuphansi kwezinga lokushisa.

2. Ukusetshenziswa okuhlukene kwe-DOP ne-DOTP

I-Dioctyl phthalate (DOP) iyi-plasticizer ebalulekile yenhloso ejwayelekile. Isetshenziswa kakhulu ekucubungulweni kwe-polyvinyl chloride resin. Ngaphandle kwalokho, ingasetshenziswa nasekucubungulweni kwama-polymer aphezulu njenge-chemical fiber resin, i-acetic acid resin, i-ABS resin, kanye nerabha. Upende, udayi, ama-dispersants, njll.

Ngaphezu kwenani elikhulu lama-plasticizer asetshenziswa ezintweni zekhebula kanye ne-PVC, i-DOTP ingasetshenziswa nasekukhiqizweni kwamafilimu esikhumba sokwenziwa. Ngaphezu kwalokho, i-DOTP ihambisana kahle kakhulu. Ngaphezu kwalokho, i-DOTP ingasetshenziswa futhi njenge-plasticizer yezinto ezitholakala ku-acrylonitrile, i-polyvinyl butyral, irabha ye-nitrile, i-nitrocellulose, njll. Ingasetshenziswa futhi njenge-plasticizer yerabha yokwenziwa, izithasiselo zopende, izithasiselo zethuluzi elinembile, izithasiselo zokugcoba, kanye nesithambisi sephepha.
