Intangiriro za DOP na DOTP

Incamake

Hari abantu bashobora kwibaza bati DOP ni iki na DOTP ni iki. Ese bafite itandukaniro? Ni izihe nyungu n'ibibi byabyo? Reka Huisu Qinye akubwire DOP na DOTP ni iki. Nanone, tuzagusobanurira neza itandukaniro riri hagati ya DOP na DOTP.

Dioctyl phthalate yitwa dioctyl ester (DOP) - imvange ya ester y’umwimerere n’ikoreshwa cyane mu gushushanya. Dioctyl phthalate ni pulasitiki y’ingenzi ikoreshwa muri rusange. Ikoreshwa cyane cyane mu gutunganya resin ya polyvinyl chloride, kandi ishobora no gukoreshwa mu gutunganya polymer nyinshi nka resin ya fibre chemical, resin ya aside acetic, resin ya ABS, na rubber. Amarangi, amarangi, ibicanwa, nibindi.

DOP ikoreshwa muri rusange: ikoreshwa cyane muri pulasitiki, rabha, amarangi, imashini zigabanya ubushyuhe, n'izindi nganda. PVC ikoreshejwe muri pulasitiki ishobora gukoreshwa mu gukora uruhu rw'ubukorano, amafirime y'ubuhinzi, ibikoresho byo gupfunyika, insinga, nibindi.

DOP y'amashanyarazi: Uretse imiterere yose ya DOP ikoreshwa muri rusange, ifite n'ubushobozi bwiza bwo gukingira amashanyarazi, ikoreshwa cyane cyane mu gukora insinga n'amashanyarazi.

DOP yo mu rwego rw'ibiribwa: ikoreshwa cyane cyane mu gukora ibikoresho byo gupfunyikamo ibiribwa.

DOP yo mu rwego rw'ubuvuzi: ikoreshwa cyane cyane mu gukora ibikoresho by'ubuvuzi n'iby'ubuzima, nk'ibikoresho byo kwa muganga bishobora gukoreshwa gahoro gahoro ndetse n'ibikoresho byo gupfunyikamo ibikoresho by'ubuvuzi.

DOTP

DOTP plasticizer ni ubundi bwoko bwa plasticizer, iki gicuruzwa ni amazi adafite ibara menshi kandi afite ubushyuhe buke. Ubushyuhe 63mPa.s (25°C), 5mPa.s (100°C), 410mPa.s (0°C). Ubukonje -48°C. Ubushyuhe bushyuha ni 383°C (0.1)MPa.s (0°C). Ubushyuhe bushyuha ni 399°C. Izina rya siyansi: dioctyl terephthalate. Ubusanzwe, twayise DOTP.

Uretse umubare munini w’udupira twa pulasitiki dukoreshwa mu bikoresho bya insinga na PVC, DOTP ishobora no gukoreshwa mu gukora firime z’uruhu rw’ubukorano. Byongeye kandi, ifite ubushobozi bwo guhuza neza kandi ishobora no gukoreshwa nk’udupira twa pulasitiki ku bintu bikomoka kuri acrylonitrile, polyvinyl butyral, nitrile rubber, nitrocellulose, nibindi.

1. Ibyiza bitandukanye bya DOP na DOTP

Ugereranyije na dioctyl phthalate (DOP) ikoreshwa cyane, dioctyl terephthalate (DOTP) ifite ibyiza byo kwirinda ubushyuhe, kurwanya ubukonje, kudahindagurika, kurwanya gukuramo amazi, koroha, no kugira ubushobozi bwiza bwo gukingira amashanyarazi. Iramba neza cyane, irwanya amazi nk'isabune, kandi yoroshye mu bushyuhe buke.

2. Imikoreshereze itandukanye ya DOP na DOTP

Dioctyl phthalate (DOP) ni pulasitiki y'ingenzi ikoreshwa muri rusange. Ikoreshwa cyane cyane mu gutunganya resin ya polyvinyl chloride. Bitabaye ibyo, ishobora no gukoreshwa mu gutunganya polymer nyinshi nka resin ya fibre chemical, resin ya aside acetic, resin ya ABS, na rubber. Amarangi, amarangi, ibicanwa, nibindi.

Uretse umubare munini w’imashini zikora pulasitiki zikoreshwa mu bikoresho bya insinga na PVC, DOTP ishobora no gukoreshwa mu gukora firime z’uruhu rw’ubukorano. Byongeye kandi, DOTP ifite ubushobozi bwo guhuza neza. Byongeye kandi, DOTP ishobora no gukoreshwa nk’imashini ikora pulasitiki ku bintu bikomoka kuri acrylonitrile, polyvinyl butyral, nitrile rubber, nitrocellulose, nibindi. Ishobora kandi gukoreshwa nk’imashini ikora pulasitiki ku bicuruzwa bya sintetike, irangi, amavuta y’ibikoresho by’ubuhanga, amavuta y’ibirungo, ndetse no koroshya impapuro.
