Isingeniso esifushane se-DOP ne-DOTP

Izingeniso ze-dop ne-dotp

Ukucubungula

Abanye abantu bangase babuze ukuthi yini i-dop futhi yini i-dotp. Ingabe banomehluko? Yini izinzuzo zabo nobunzima babo? Vumela uHuisu Qtene akutshele ukuthi yini i-dop ne-dotp. Futhi, sizokwenza wazi kangcono ngomehluko phakathi kweDop ne-DoTP.

UDioctyl perthalate ubizwa ngokuthi yi-dioctyl ester (dop) - i-organic ester compound kanye nenqubo esetshenziswa kakhulu. I-Dioctyl phthalate iyipulasitiki ebalulekile ebalulekile. Isetshenziswa kakhulu ekucutshungulweni kwe-polyvinyl chloride resin, futhi futhi ingasetshenziswa ekucuthulweni kwama-polymers aphezulu anjenge-resin yamakhemikhali, i-acetic acid resin, i-abber resin, nerabha. Amapende, udayi, ama-dispersants, njll.

I-General-Inhloso DOP: Kusetshenziswe kabanzi kumapulasitiki, irabha, upende, ama-emulsifiers, kanye nezinye izimboni. I-PVC ipulasitiki evikelwe nayo ingasetshenziselwa ukwenza isikhumba sokufakelwa, amafilimu ezolimo, izinto zokupakisha, izintambo, njll.

I-Electrical Dop: Ngaphezu kwazo zonke izakhiwo ze-DOP enenhloso ejwayelekile, futhi inezakhiwo ezinhle zokufakwa kukagesi, ezisetshenziswa kakhulu ekukhiqizweni kwezintambo nogesi.

I-DOP yeBanga Lokudla: Isetshenziswa kakhulu ekukhiqizweni kwezinto zokupakisha zokudla.

I-DOP yebanga lezokwelapha: Isetshenziselwa ikakhulukazi ukukhiqizwa kwemikhiqizo yezokwelapha nezempilo, njengokusetshenziswa kwezokwelapha okulahlwayo kanye nezinto zokupakisha ezokwelashwa.

I-DoTP

I-Dotp Plasticesizer yilolunye uhlobo lwamapulasitiki, lo mkhiqizo uwuketshezi olucishe lube khona aluhlaza okotshani. I-Viscocity 63MPA.S (25 ° C), 5MPA.S (100 ° C), 410MPA.S (0 ° C). Iphoyinti le-FreeZing -48 ° C. Iphuzu elibilayo lingu-383 ° C (0.1) MPA.S (0 ° C). Iphuzu lokulahla lingama-399 ° C. Igama leSayensi: Dioctyl Terephthalate. Imvamisa, sayibiza ngokuthi yi-DoTP.

Ngaphezu kwenani elikhulu lamapulasitiki asetshenziswa ezintweni zokwakha amakhebula kanye ne-PVC, i-DoTP nayo ingasetshenziswa ekukhiqizweni kwamafilimu wesikhumba okufakelwa. Ngaphezu kwalokho, inokuhambisana okuhle kakhulu futhi futhi ingasetshenziswa njenge-spitizer ye-acrylonitrile derivatives, i-polyvinyl buyyral, i-nitrile ruble, i-nitrocellulose, njll.

1. Izinzuzo ezahlukene ze-dop ne-dotp

Uma kuqhathaniswa ne-dioctyl esetshenziswa kakhulu ye-dioctyl perthalate (dop), i-dioctyl terephthalate (DoCP) inezinzuzo zokumelana nokushisa, ukumelana nokubandakanyeka, ukukhishwa, ukukhishwa, nokuguquguquka, kanye nezinto ezinhle zokufakwa kukagesi. Ukuqina okuhle kakhulu, ukumelana kwamanzi kwensipho, kanye nokuthamba okushisa okuphansi.

2. Ukusetshenziswa okuhlukile kwe-dop ne-dotp

I-Dioctyl phthalate (dop) ipulasitiki ebalulekile ebalulekile. Isetshenziswa ikakhulukazi ekucutshungweni kwe-polyvinyl chloride resin. Ngaphandle kwalokho, ingasetshenziswa futhi ekucutshungulweni kwama-polymers aphezulu anjenge-chemifi fiber resin, acetic acid resin, abs resin, nerabha. Amapende, udayi, ama-dispersants, njll.

Ngaphezu kwenani elikhulu lamapulasitiki asetshenziswa ezintweni zokwakha amakhebula kanye ne-PVC, i-DoTP nayo ingasetshenziswa ekukhiqizweni kwamafilimu wesikhumba okufakelwa. Ngaphezu kwalokho, i-DOTP inokuhambisana okuhle kakhulu. Ngaphezu kwalokho, i-DOTP ingahle futhi isetshenziswe njengepulasitiki yokutholwa kokutholwa kwe-acrylonitrite, i-polyvinyl buyyral, i-nitrile ruble, i-nitrocellulose, njll. Kungasetshenziswa futhi njenge-spitifizer yensimbi, ukugcoba izithasiselo zokuthemba, kanye nethafa lephepha.
