Isingeniso Esifushane se-DOP ne-DOTP

Izethulo ze-DOP ne-DOTP

Uhlolojikelele

Abanye abantu bangabuza ukuthi yini i-DOP nokuthi iyini i-DOTP. Ingabe banomehluko? Yiziphi izinzuzo zabo kanye nebubi bazo? Vumela u-Huisu Qinye akutshele ukuthi yini i-DOP ne-DOTP. Futhi, sizokwenza wazi kangcono ngomehluko phakathi kwe-DOP ne-DOTP.

I-Dioctyl phthalate ibizwa nge-dioctyl ester (DOP) - inhlanganisela ye-organic ester kanye ne-plasticizer esetshenziswa kakhulu. I-Dioctyl phthalate iyi-plasticizer ebalulekile yenhloso evamile. Isetshenziswa kakhulu ekucubunguleni i-polyvinyl chloride resin, futhi ingasetshenziswa ekucubunguleni ama-polymer aphezulu njenge-chemical fiber resin, i-acetic acid resin, i-ABS resin, nerabha. Amapende, amadayi, ama-disperants, njll.

I-DOP yenhloso ejwayelekile: isetshenziswa kakhulu kumapulasitiki, irabha, amapende, ama-emulsifiers, nezinye izimboni. I-PVC eyenziwe ngepulasitiki nayo ingasetshenziswa ukwenza isikhumba sokwenziwa, amafilimu ezolimo, izinto zokupakisha, izintambo, njll.

I-DOP kagesi: Ngaphezu kwazo zonke izakhiwo ze-DOP yenhloso evamile, iphinde ibe nezindawo ezinhle zokuvala ugesi, ezisetshenziswa kakhulu ekukhiqizeni izintambo nogesi.

Ibanga lokudla i-DOP: esetshenziswa kakhulu ekukhiqizeni izinto zokupakisha ukudla.

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

I-DOTP

I-DOTP plasticizer ingolunye uhlobo lwe-plasticizers, lo mkhiqizo uwuketshezi olungenambala olune-viscosity ephansi. I-Viscosity 63mPa.s (25°C), 5mPa.s (100°C), 410mPa.s (0°C). Indawo yokubanda -48°C. Iphuzu elibilayo lingu-383°C (0.1)MPa.s (0°C). Indawo yokuthungela ingu-399°C. Igama lesayensi: i-dioctyl terephthalate. Ngokuvamile, sasiyibiza ngokuthi i-DOTP.

Ngaphezu kwenani elikhulu lama-plasticizers asetshenziswa ezintweni zekhebula kanye ne-PVC, i-DOTP ingasetshenziswa futhi ekukhiqizeni amafilimu esikhumba okwenziwa. Ngaphezu kwalokho, inokuhambisana okuhle kakhulu futhi ingasetshenziswa njenge-plasticizer ye-acrylonitrile derivatives, i-polyvinyl butyral, irabha ye-nitrile, i-nitrocellulose, njll.

1. Izinzuzo ezahlukene ze-DOP ne-DOTP

Uma kuqhathaniswa ne-dioctyl phthalate (DOP) evame ukusetshenziswa, i-dioctyl terephthalate(DOTP) inezinzuzo zokumelana nokushisa, ukumelana nokubanda, okungaguquguquki, okulwa nokukhipha, ukuguquguquka, kanye nezakhiwo ezinhle zokuvala ugesi. Ukuqina okuhle kakhulu, ukumelana namanzi anensipho, nokuthamba kwezinga lokushisa eliphansi.

2. Izinhlelo zokusebenza ezehlukene ze-DOP ne-DOTP

I-Dioctyl phthalate(DOP) iyi-plasticizer ebalulekile yenjongo evamile. Isetshenziswa kakhulu ekucubunguleni i-polyvinyl chloride resin. Uma kungenjalo, ingasetshenziswa futhi ekucubunguleni ama-polymer aphezulu njenge-chemical fiber resin, i-acetic acid resin, i-ABS resin, nerabha. Amapende, amadayi, ama-disperants, njll.

Ngaphezu kwenani elikhulu lama-plasticizers asetshenziswa ezintweni zekhebula kanye ne-PVC, i-DOTP ingasetshenziswa futhi ekukhiqizeni amafilimu esikhumba okwenziwa. Ngaphezu kwalokho, i-DOTP inokuhambisana okuhle kakhulu. Ngaphezu kwalokho, i-DOTP ingasetshenziswa futhi njenge-plasticizer ye-acrylonitrile derivatives, i-polyvinyl butyral, irabha ye-nitrile, i-nitrocellulose, njll. Ingasetshenziswa futhi njenge-plasticizer yerabha yokwenziwa, izithasiselo zopende, izithambisi zensimbi ezinembayo, izithasiselo zokuthambisa, nanjengesithambisa sephepha.
