He Hoʻolauna Pōkole i ka DOP a me ka DOTP

ʻO ka hoʻolauna ʻana o DOP a me DOTP

ʻIke laulā

E nīnau paha kekahi poʻe he aha ka DOP a he aha ka DOTP. He ʻokoʻa ko lākou? He aha ko lākou mau pono a me nā hemahema o lākou? E haʻi aku ʻo Huisu Qinye iā ʻoe i ke ʻano o ka DOP a me ka DOTP. Eia kekahi, e hoʻomaopopo maikaʻi mākou iā ʻoe e pili ana i ka ʻokoʻa ma waena o DOP a me DOTP.

Ua kapa ʻia ʻo Dioctyl phthalate ʻo dioctyl ester (DOP) - kahi hui ester organik a me kahi plasticizer i hoʻohana pinepine ʻia. ʻO Dioctyl phthalate kahi plasticizer kumu nui. Hoʻohana nui ʻia ia i ka hana ʻana o ka resin polyvinyl chloride, a hiki ke hoʻohana ʻia i ka hana ʻana o nā polymers kiʻekiʻe e like me ka resin fiber kemika, ka resin acetic acid, ka resin ABS, a me ka rubber. Nā pena, nā kala, nā mea hoʻolaha, a pēlā aku.

DOP kumu maʻamau: hoʻohana nui ʻia i nā plastik, laholio, pena, emulsifiers, a me nā ʻoihana ʻē aʻe. Hiki ke hoʻohana ʻia ka PVC plasticized me ia e hana i ka ʻili hana, nā kiʻiʻoniʻoni mahiʻai, nā mea hoʻopili, nā kaula, a pēlā aku.

DOP Uila: Ma waho aʻe o nā waiwai āpau o ka DOP kumu maʻamau, loaʻa iā ia nā waiwai insulation uila maikaʻi, i hoʻohana nui ʻia i ka hana ʻana o nā uea a me ka uila.

ʻO ka DOP papa meaʻai: hoʻohana nui ʻia i ka hana ʻana o nā mea hoʻopili meaʻai.

ʻO ka DOP papa lapaʻau: hoʻohana nui ʻia no ka hana ʻana i nā huahana lapaʻau a me ke olakino, e like me nā lako lapaʻau hoʻolei a me nā mea hoʻopili lāʻau lapaʻau.

DOTP

ʻO ka plasticizer DOTP kekahi ʻano plasticizer ʻē aʻe, he wai viscosity haʻahaʻa kēia huahana. Viscosity 63mPa.s (25°C), 5mPa.s (100°C), 410mPa.s (0°C). Wahi hau -48°C. ʻO ke kiko paila he 383°C (0.1)MPa.s (0°C). ʻO ke kiko hoʻā ʻana he 399°C. Inoa ʻepekema: dioctyl terephthalate. ʻO ka maʻamau, ua kapa mākou iā ia ʻo DOTP.

Ma waho aʻe o ka nui o nā plasticizers i hoʻohana ʻia i nā mea kaula a me PVC, hiki ke hoʻohana ʻia ʻo DOTP i ka hana ʻana i nā kiʻiʻoniʻoni ʻili artificial. Eia kekahi, he kūpono loa ia a hiki ke hoʻohana ʻia ma ke ʻano he plasticizer no nā derivatives acrylonitrile, polyvinyl butyral, nitrile rubber, nitrocellulose, a pēlā aku.

1. Nā pono like ʻole o DOP a me DOTP

Ke hoʻohālikelike ʻia me ka dioctyl phthalate (DOP) i hoʻohana pinepine ʻia, loaʻa i ka dioctyl terephthalate (DOTP) nā pono o ke kūpaʻa wela, ke kūpaʻa anu, ka non-volatile, ka anti-extraction, ka maʻalahi, a me nā waiwai insulation uila maikaʻi. ʻO ke kūpaʻa maikaʻi loa, ke kūpaʻa wai kopa, a me ka palupalu haʻahaʻa.

2. Nā noi like ʻole o DOP a me DOTP

He mea hoʻohuihui koʻikoʻi ka Dioctyl phthalate (DOP). Hoʻohana nui ʻia ia i ka hana ʻana o ka resin polyvinyl chloride. A i ʻole, hiki ke hoʻohana ʻia i ka hana ʻana o nā polymers kiʻekiʻe e like me ka resin fiber kemika, ka resin acetic acid, ka resin ABS, a me ka rubber. Nā pena, nā dyes, nā dispersants, a pēlā aku.

Ma waho aʻe o ka nui o nā plasticizers i hoʻohana ʻia i nā mea kaula a me PVC, hiki ke hoʻohana ʻia ʻo DOTP i ka hana ʻana i nā kiʻiʻoniʻoni ʻili artificial. Eia kekahi, loaʻa iā DOTP ka hoʻohālikelike maikaʻi loa. Eia kekahi, hiki ke hoʻohana ʻia ʻo DOTP ma ke ʻano he plasticizer no nā derivatives acrylonitrile, polyvinyl butyral, nitrile rubber, nitrocellulose, a pēlā aku. Hiki ke hoʻohana ʻia ma ke ʻano he plasticizer no ka synthetic rubber, nā mea hoʻohui pena, nā lubricants mea hana pololei, nā mea hoʻohui lubricant, a ma ke ʻano he mea palupalu no ka pepa.
