I-2-Ethylhexyl diphenyl phosphate (EHDP, DPOP, Santicizer® 141, CAS 1241-94-7) iyinhlanganisela ye-organophosphate ester enefomula yamangqamuzana ethi C₂₀H₂₇O₄P kanye nesisindo samangqamuzana esingu-362.41 g/mol. Ibonakala njengoketshezi olungenambala noma oluphuzi ngokukhanyayo, olucacile, olune-viscosity ephansi futhi olunephunga elimnandi kancane. Lesi sengezo esingena-halogen, esisebenza ngempumelelo ephezulu sisebenza ngendlela eyingqayizivele njengomuthi wokuvimbela umlilo kanye nesithako sokuthambisa—amandla okusebenza kabili aziwa ngokuthi isithako sokuthambisa esivimbela umlilo. I-EHDP yaziswa kakhulu ngokuhlangana kwayo okusheshayo, izakhiwo zayo ezinhle kakhulu zokujiyisa, kanye nokuhambisana kwayo okumangalisayo nezinhlobonhlobo zama-polymer, okuhlanganisa i-PVC, i-TPU, i-NBR, i-cellulose acetate, ama-acrylic, ama-epoxy, nama-polyester. Ukungaguquguquki kwayo okuphansi (iphoyinti lomlilo: 224°C) kanye nokumelana kwayo kahle nezimo zezulu kuyenza ibe yisinqumo esifanele ezinhlelweni lapho ukunciphisa ingozi yomlilo kuyinto ebalulekile.

Izinhlelo Zokusebenza
I-2-Ethylhexyl diphenyl phosphate iyisengezo sokuvimbela umlilo esiguquguqukayo esisetshenziswa ezimbonini eziningi:
| Umkhakha Wokusetshenziswa | Izinsetshenziswa Eziyinhloko |
|---|---|
| PVC (Polyvinyl Chloride) | Isetshenziswa njenge-plasticizer eyinhloko noma yesibili ezinhlelweni ze-PVC eguquguqukayo ezihlanganisa ukufakwa kwezintambo kanye nekhebula, phansi, izindwangu ezimboziwe, amabhande e-conveyor, amapayipi, nama-foam esakhiwo. I-EHDP inikeza i-gelation enhle kakhulu, ukuhlangana okusheshayo, nokuvimbela umlilo ngaphandle kokulimaza ukuguquguquka. |
| TPU (I-Thermoplastic Polyurethane) | Isebenza njengesengezo sokuvimbela umlilo ku-TPU yezinto zangaphakathi zezimoto, amakhasi ezinto zikagesi, kanye nezingxenye zezimboni ezidinga ukuvimbela umlilo nokuqina. |
| Izixube Ze-Rubber (NBR, SBR, njll.) | Kuthuthukisa ukuvimbela umlilo kanye nokuguquguquka kokucubungula ku-nitrile butadiene rubber (NBR) kanye nezinye izinhlobo ze-rubber yokwenziwa kuma-gaskets, izivalo, namapayipi e-industrial. |
| I-Cellulose Acetate Namanye Ama-Resin | Isetshenziswa njenge-plasticizer kanye nesivimbeli somlilo ku-cellulose acetate kumafreyimu ezibuko, izibambo zamathuluzi, kanye nezimpahla zabathengi; futhi iyahambisana nama-acrylics, i-epoxy, i-polyester, kanye nama-resin e-phenolic. |
| Ama-Coatings & Ama-Adhesives | Ithuthukisa ukumelana nomlilo nokuguquguquka kuma-coatings ezimbonini, ama-adhesives, nama-sealants asekelwe kuma-resin okwenziwa nama-rubber. |
| Izinto Zokugcoba Nezoketshezi Lwe-Hydraulic | Isebenza njengesengezo sokuvimbela umlilo kuketshezi lwe-hydraulic kanye nezinto zokugcoba ezisetshenziswa ezingeni lokushisa eliphezulu, okuhlanganisa nezinhlelo ezinkulu ze-hydraulic zezindiza. |
Izinzuzo Eziyinhloko Zokusebenza:
- Isivimbamillo esingena-halogen – Sihlangabezana nemithetho eqinile yezemvelo kanye namazinga okuhambisana ne-RoHS/REACH.
- Ukuncibilika okusheshayo nokuncibilikisa okuphezulu – Kuthuthukisa ukusebenza kahle kokucubungula nokuhambisana nama-polymer.
- Ukuguquguquka okuphansi nokumelana nokufuduka – Kugcina ukuzinza kokusebenza esikhathini eside sokusebenza.
- Ukumelana nesimo sezulu okuhle kakhulu – Kuthuthukisa ukumelana nesimo sezulu, ukumelana nokuhuzuka, kanye nokumelana nomswakama emikhiqizweni eseqediwe.
- Ukusebenza ngokubambisana – Kusebenza kahle nama-phthalate plasticizers ukuthuthukisa ukuqina komkhiqizo, ukumelana nesimo sezulu, namandla okudonsa kumafilimu e-PVC.
