Gusaba

Antioxidant DSTDP ni antioxydants nziza yingirakamaro kandi ikoreshwa cyane muri polypropilene, polyethylene, chloride polyvinyl, ABS hamwe namavuta yo gusiga.Ifite gushonga cyane no guhindagurika.

DSTDP irashobora kandi gukoreshwa ifatanije na antioxydants ya fenolike na sisitemu ya ultraviolet kugirango itange umusaruro.

Urebye gukoresha inganda, urashobora kwifashisha amahame atanu akurikira yo guhitamo:

1. Guhagarara

Mugihe cyibikorwa byo gukora, antioxydeant igomba kuguma ihagaze neza, ntigihindurwe byoroshye, ntigire ibara (cyangwa idafite ibara), ntigishobora kubora, ntigisubizwe hamwe nibindi byongeweho imiti, kandi ntigire icyo ikora hamwe nibindi byongewemo imiti mugihe cyo gukoresha ibidukikije no gutunganya ubushyuhe bwinshi.Ibindi bintu biri hejuru birahanahana kandi ntibishobora kwangiza ibikoresho byumusaruro, nibindi.

2. Guhuza

Makromolekula ya polymers ya plastike muri rusange ntabwo ari polar, mugihe molekile ya antioxydants ifite dogere zitandukanye za polarite, kandi byombi ntibishobora guhuza.Molekile ya Antioxydeant iba hagati ya molekile ya polymer mugihe cyo gukira.

3. Kwimuka

Imyuka ya okiside yibicuruzwa byinshi ibaho cyane cyane murwego ruto, bisaba guhora kwimura antioxydants kuva imbere mubicuruzwa kugeza hejuru kugirango bikore.Ariko, niba igipimo cyo kwimura cyihuta cyane, biroroshye guhindagurika mubidukikije no kubura.Iki gihombo ntigishobora kwirindwa, ariko turashobora gutangirana nigishushanyo mbonera kugirango tugabanye igihombo.

4. Gutunganya

Niba itandukaniro riri hagati yo gushonga kwa antioxydeant hamwe nu ntera yo gushonga yibikoresho bitunganyirizwa ari binini cyane, ibintu byo gutwarwa na anti-okiside cyangwa umugozi wa anti-okiside bizabaho, bikavamo gukwirakwiza antioxydants mu bicuruzwa.Kubwibyo, iyo gushonga kwa antioxydeant iri munsi yubushyuhe bwo gutunganya ibintu hejuru ya 100 ° C, antioxydeant igomba gukorwa muburyo bukomeye bwibintu runaka, hanyuma ikavangwa na resin mbere yo kuyikoresha.

5. Umutekano

Hagomba kubaho imirimo yubukorikori mugikorwa cyo kubyaza umusaruro, bityo antioxydeant igomba kuba idafite uburozi cyangwa uburozi buke, butagira umukungugu cyangwa umukungugu muke, kandi ntibizagira ingaruka mbi kumubiri wumuntu mugihe cyo gutunganya cyangwa kubikoresha, kandi nta mwanda uhari ku bidukikije.Nta ngaruka mbi ku nyamaswa n'ibimera.

Antioxydants ni ishami ryingenzi rya polymer stabilisateur.Mugihe cyo gutunganya ibikoresho, hagomba kwitabwaho cyane mugihe, ubwoko nubwinshi bwa antioxydants yongeweho kugirango wirinde kunanirwa bitewe nibidukikije.
