Xingheniso xo Koma xa DOP na DOTP

Swingheniso swa DOP na DOTP

Nkatsakanyo

Vanhu van’wana va nga ha vutisa leswaku DOP i yini naswona DOTP i yini. Xana va ni ku hambana? Hi yihi mimpfuno ni ku biha ka tona eka tona? Huisu Qinye a ku byele leswaku i yini DOP na DOTP. Nakambe, hi ta ku tivisa ku antswa hi ku hambana exikarhi ka DOP na DOTP.

Dioctyl phthalate yivuriwa dioctyl ester (DOP) - organic ester compound xikan’we na plasticizer leyi tirhisiwaka ngopfu. Dioctyl phthalate i plasticizer ya nkoka ya xikongomelo xo angarhela. Yitirhisiwa ngopfu eka ku lulamisiwa ka polyvinyl chloride resin, naswona yinga tlhela yitirhisiwa eka ku lulamisiwa ka ti polymers tale henhla tofana na chemical fibre resin, acetic acid resin, ABS resin, na rhaba. Tipende, tidayi, swilo swo hangalasa, na swin’wana.

DOP ya xikongomelo xo angarhela: yi tirhisiwa ngopfu eka tipulasitiki, rhaba, tipende, ti emulsifiers, na tiindasitiri tin’wana. PVC leyi endliweke plastiki hi yona yinga tirhisiwa ku endla dzovo ro endliwa, tifilimi ta vurimi, switirhisiwa swo paka, tikhebulu, na swin’wana.

DOP ya gezi: Ku engetela eka swivumbeko hinkwaswo swa DOP ya xikongomelo xo angarhela, yitlhela yiva na swivumbeko swa kahle swo pfalela gezi, ngopfu ngopfu leswi tirhisiwaka eka vuhumelerisi bya tintambhu na gezi.

Food grade DOP: ngopfu ngopfu yitirhisiwa eka vuhumelerisi bya switirhisiwa swo paka swakudya.

Giredi ya swa vutshunguri DOP: ngopfu ngopfu yitirhisiwa eka vuhumelerisi bya switirhisiwa swa vutshunguri na swa rihanyo, kufana na switirhisiwa swa vutshunguri leswi lahliwaka na switirhisiwa swo paka swa vutshunguri.

DOTP

DOTP plasticizer i muxaka wun’wana wa ti plasticizers, xitirhisiwa lexi i kwalomu ka muhlovo wa low-viscosity liquid. Ku tsindziyela ka 63mPa.s (25°C), 5mPa.s (100°C), 410mPa.s (0°C). Nhlayo ya ku titimela -48°C. Nhlayo ya ku vila i 383°C (0.1)MPa.s (0°C). Nhlayo ya ku pfurha i 399°C. Vito ra sayense: dioctyl terephthalate. Hi ntolovelo, a hi yi vitana DOTP.

Ku engetela eka nhlayo leyikulu ya ti plasticizers leti tirhisiwaka eka switirhisiwa swa ti cable na PVC, DOTP yinga tlhela yitirhisiwa eka vuhumelerisi bya ti artificial leather films. Ku engetela kwalano, yina ku fambisana kahle swinene naswona yinga tlhela yitirhisiwa tani hi plasticizer ya ti acrylonitrile derivatives, polyvinyl butyral, nitrile rubber, nitrocellulose, na swin’wana.

1. Swipfuno swo hambana swa DOP na DOTP

Loko ku pimanyisiwa na dioctyl phthalate (DOP) leyi tirhisiwaka ngopfu, dioctyl terephthalate(DOTP) yina swipfuno swaku lwisana na kuhisa, ku lwisana na xirhami, leswinga khulukiki, anti-extraction, ku olova, na swivumbeko swa kahle swa ku pfalela gezi. Ku tiya swinene, ku tiya ka mati ya xisibi, na ku olova ka mahiselo yale hansi.

2. Switirhisiwa swo hambana swa DOP na DOTP

Dioctyl phthalate(DOP) i plasticizer ya nkoka ya xikongomelo xo angarhela. Yitirhisiwa ngopfu eka ku lulamisiwa ka polyvinyl chloride resin. Handle ka sweswo, yinga tlhela yitirhisiwa eka ku lulamisiwa ka ti polymers tale henhla tofana na chemical fibre resin, acetic acid resin, ABS resin, na rhaba. Tipende, tidayi, swilo swo hangalasa, na swin’wana.

Ku engetela eka nhlayo leyikulu ya ti plasticizers leti tirhisiwaka eka switirhisiwa swa ti cable na PVC, DOTP yinga tlhela yitirhisiwa eka vuhumelerisi bya ti artificial leather films. Ku engetela kwalaho, DOTP yi na ku fambisana lokunene. Ku tlula kwalaho, DOTP yinga tlhela yitirhisiwa tani hi plasticizer ya acrylonitrile derivatives, polyvinyl butyral, nitrile rubber, nitrocellulose, etc. Yinga tlhela yitirhisiwa tani hi plasticizer ya synthetic rubber, swiengeteri swa pende, precision instrument lubricants, lubricant additives, na tani hi softener ya maphepha.
