Chiyambi Chachidule cha DOP ndi DOTP

Kuyambitsa kwa DOP ndi DOTP

Chidule

Anthu ena angafunse kuti DOP ndi chiyani ndipo DOTP ndi chiyani. Kodi ali ndi kusiyana kotani? Kodi ubwino ndi kuipa kwake ndi kotani? Lolani Huisu Qinye akuuzeni kuti DOP ndi DOTP ndi chiyani. Komanso, tidzakudziwitsani bwino za kusiyana pakati pa DOP ndi DOTP.

Dioctyl phthalate imatchedwa dioctyl ester (DOP) - chinthu cha organic ester komanso pulasitiki yomwe imagwiritsidwa ntchito kwambiri. Dioctyl phthalate ndi pulasitiki yofunika kwambiri. Imagwiritsidwa ntchito kwambiri pokonza polyvinyl chloride resin, ndipo ingagwiritsidwenso ntchito pokonza ma polima ambiri monga ulusi wa mankhwala, acetic acid resin, ABS resin, ndi rabara. Utoto, utoto, zosakaniza, ndi zina zotero.

DOP yogwiritsidwa ntchito nthawi zonse: imagwiritsidwa ntchito kwambiri mu mapulasitiki, rabara, utoto, ma emulsifier, ndi mafakitale ena. PVC yokhala ndi pulasitiki ingagwiritsidwe ntchito popanga zikopa zopanga, mafilimu a zaulimi, zipangizo zopakira, zingwe, ndi zina zotero.

DOP Yamagetsi: Kuwonjezera pa makhalidwe onse a DOP yogwiritsidwa ntchito nthawi zonse, ilinso ndi mphamvu zabwino zotetezera magetsi, zomwe zimagwiritsidwa ntchito makamaka popanga mawaya ndi magetsi.

DOP ya kalasi ya chakudya: imagwiritsidwa ntchito makamaka popanga zinthu zopangira chakudya.

DOP ya digiri ya zamankhwala: imagwiritsidwa ntchito makamaka popanga zinthu zachipatala ndi zaumoyo, monga zida zachipatala zotayidwa ndi zinthu zina zopakira mankhwala.

DOTP

DOTP plasticizer ndi mtundu wina wa ma plasticizer, mankhwalawa ndi madzi opanda mtundu komanso otsika kukhuthala. Kukhuthala 63mPa.s (25°C), 5mPa.s (100°C), 410mPa.s (0°C). Malo ozizirira -48°C. Malo otentha ndi 383°C (0.1)MPa.s (0°C). Malo oyatsira ndi 399°C. Dzina la sayansi: dioctyl terephthalate. Nthawi zambiri, tinkatcha DOTP.

Kuwonjezera pa mapulasitiki ambiri omwe amagwiritsidwa ntchito popanga zingwe ndi PVC, DOTP ingagwiritsidwenso ntchito popanga mafilimu a chikopa chopangidwa. Kuphatikiza apo, imagwirizana bwino kwambiri ndipo ingagwiritsidwenso ntchito ngati pulasitiki ya acrylonitrile derivatives, polyvinyl butyral, nitrile rabara, nitrocellulose, ndi zina zotero.

1. Ubwino wosiyanasiyana wa DOP ndi DOTP

Poyerekeza ndi dioctyl phthalate (DOP) yomwe imagwiritsidwa ntchito kwambiri, dioctyl terephthalate (DOTP) ili ndi ubwino wokana kutentha, kukana kuzizira, kusasinthasintha, kukana kutulutsa, kusinthasintha, komanso mphamvu zabwino zotetezera magetsi. Kulimba bwino kwambiri, kukana madzi a sopo, komanso kufewa pang'ono kutentha.

2. Kugwiritsa ntchito kosiyanasiyana kwa DOP ndi DOTP

Dioctyl phthalate (DOP) ndi pulasitiki wofunika kwambiri wogwiritsidwa ntchito popanga zinthu zosiyanasiyana. Amagwiritsidwa ntchito kwambiri popanga utomoni wa polyvinyl chloride. Kupanda kutero, ingagwiritsidwenso ntchito popanga ma polima ambiri monga utomoni wa ulusi wa mankhwala, utomoni wa acetic acid, utomoni wa ABS, ndi rabara. Utoto, utoto, zotulutsira zinthu, ndi zina zotero.

Kuwonjezera pa mapulasitiki ambiri omwe amagwiritsidwa ntchito popanga zingwe ndi PVC, DOTP ingagwiritsidwenso ntchito popanga mafilimu a chikopa chopangidwa. Kuphatikiza apo, DOTP imagwirizana bwino kwambiri. Kuphatikiza apo, DOTP ingagwiritsidwenso ntchito ngati pulasitiki ya acrylonitrile derivatives, polyvinyl butyral, nitrile rabara, nitrocellulose, ndi zina zotero. Ingagwiritsidwenso ntchito ngati pulasitiki ya rabara yopangidwa, zowonjezera utoto, mafuta odzola zida zolondola, zowonjezera mafuta, komanso ngati chofewetsa mapepala.
