Kutanga kweDOP neDOTP

Pfupiso

Vamwe vanhu vangabvunza kuti chii chinonzi DOP uye chii chinonzi DOTP. Vane musiyano here? Ndezvipi zvakanakira nekuipira kwavo? Regai Huisu Qinye akuudzei kuti chii chinonzi DOP neDOTP. Zvakare, tichakuzivisai zviri nani nezvemusiyano uripo pakati peDOP neDOTP.

Dioctyl phthalate inonzi dioctyl ester (DOP) - chinhu chinonzi organic ester compound uye chinoshandiswa zvakanyanya mupurasitiki. Dioctyl phthalate chinhu chakakosha chepurasitiki chinoshandiswa zvakanyanya. Chinonyanya kushandiswa mukugadzirisa polyvinyl chloride resin, uye chinogona kushandiswawo mukugadzirisa mapolymers akawanda akadai se chemical fiber resin, acetic acid resin, ABS resin, uye rabha. Pendi, madhayi, zvinoparadzira, nezvimwewo.

DOP inoshandiswa zvakanyanya: inoshandiswa zvakanyanya mumapurasitiki, rabha, pendi, emulsifiers, nedzimwe nzvimbo dzeindasitiri. PVC yakashongedzwa nayo inogona kushandiswa kugadzira dehwe rekugadzira, mafirimu ekurima, zvinhu zvekurongedza, tambo, nezvimwewo.

DOP yemagetsi: Pamusoro pezvinhu zvese zveDOP inoshandiswa zvakanyanya, inewo zvinhu zvakanaka zvekudzivirira kupisa, zvinonyanya kushandiswa mukugadzira waya nemagetsi.

DOP yemhando yekudya: inonyanya kushandiswa mukugadzira zvinhu zvekurongedza chikafu.

DOP yemhando yekurapa: inonyanya kushandiswa kugadzira zvigadzirwa zvehutano, zvakaita semidziyo yekurapa inoraswa uye zvinhu zvekurongedza zvekurapa.

DOTP

DOTP plasticizer ndeimwe mhando yeplasticizers, chigadzirwa ichi chinwiwa chisina ruvara chine viscosity yakaderera. Viscosity 63mPa.s (25°C), 5mPa.s (100°C), 410mPa.s (0°C). Nzvimbo yechando -48°C. Nzvimbo yekubikira i383°C (0.1)MPa.s (0°C). Nzvimbo yekupisa i399°C. Zita resainzi: dioctyl terephthalate. Kazhinji, taichitumidza kuti DOTP.

Pamusoro pemapurasitiki akawanda anoshandiswa mumidziyo yetambo nePVC, DOTP inogona kushandiswawo mukugadzira mafirimu eganda rekugadzira. Pamusoro pezvo, inoenderana zvakanaka uye inogona kushandiswawo sepurasitiki yeacrylonitrile derivatives, polyvinyl butyral, nitrile rabha, nitrocellulose, nezvimwewo.

1. Mabhenefiti akasiyana eDOP neDOTP

Kana tichienzanisa nedioctyl phthalate (DOP) inowanzoshandiswa, dioctyl terephthalate (DOTP) ine zvakanakira zvekudzivirira kupisa, kudzivirira kutonhora, kusachinja-chinja, kudzivirira kuburitsa mvura, kuchinjika, uye hunhu hwakanaka hwekudzivirira kupisa. Inogara kwenguva refu, inodzivirira mvura nesipo, uye inonyorova pakupisa kwakaderera.

2. Mashandisirwo akasiyana eDOP neDOTP

Dioctyl phthalate (DOP) chinhu chakakosha chepurasitiki chinoshandiswa zvakanyanya. Chinonyanya kushandiswa mukugadzirisa polyvinyl chloride resin. Kana zvisina kudaro, inogona zvakare kushandiswa mukugadzirisa mapolymers akawanda akadai se chemical fiber resin, acetic acid resin, ABS resin, uye rabha. Pendi, madhayi, zvinoparadzira, nezvimwewo.

Pamusoro pemapurasitiki akawanda anoshandiswa mumidziyo yetambo nePVC, DOTP inogona kushandiswawo mukugadzira mafirimu eganda rekugadzira. Pamusoro pezvo, DOTP inoenderana zvakanaka. Uyezve, DOTP inogona kushandiswawo sepurasitiki yeacrylonitrile derivatives, polyvinyl butyral, nitrile rabha, nitrocellulose, nezvimwewo. Inogona zvakare kushandiswa sepurasitiki yerabha rekugadzira, pendi, mafuta ekushandisa akakodzera, mafuta ekuwedzera, uye sechinyorovesa pepa.
