Kuki plastiki yera ihinduka umuhondo nyuma yigihe kinini?

Muri rusange, umuhondo wibicuruzwa bya plastiki biterwa no gusaza cyangwa gutesha agaciro ibikoresho.Muri rusange,PPbiterwa no gusaza (degradation).Bitewe no kubaho kwamatsinda kuruhande kuri polypropilene, ituze ryayo ntabwo ari ryiza, cyane cyane kumucyo.Mubisanzwe, urumuri rutanga urumuri rwongeyeho.NahoPE, kubera ko nta shingiro ryuruhande, ntabibazo byinshi byumuhondo mugutunganya rusange cyangwa gukoresha hakiri kare.PVCizahinduka umuhondo, ifitanye isano rya hafi na formulaire yibicuruzwa.Kubivuga neza, ni okiside.Ubuso bwibikoresho bimwe byoroshye biroroshye okiside, birakenewe rero ko bivura hejuru yubushakashatsi.

Usibye inyongeramusaruro mbi numwanda muri sisitemu, ngira ngo ahanini biterwa no gusaza.Ongeraho sisitemu ikwiye ya antioxydeant hamwe na anti-ultraviolet irashobora kunonosora umuhondo wa PE na PP, ariko sisitemu nyinshi zibuza antioxydants ya fenolike ubwayo izazana umuhondo muto.Byongeye kandi, sisitemu zimwe na zimwe za antioxydeant hamwe na anti-ultraviolet zifite ingaruka zo kurwanya, rero witonde mugihe ubikoresha.Polymer lubricant yongeweho kugirango ikore firime ya fluoropolymer itemba kurukuta rwimashini, kunoza imikorere yo gutunganya ibicuruzwa, umuvuduko ukabije hamwe nubushyuhe bwo gutunganya ubushyuhe bwa polyolefin, kuzamura ubwiza bwibicuruzwa n’umusaruro, kugabanya ibiciro by’umusaruro, kugabanya cyangwa gukuraho kuvunika gushonga, no kugabanya ibishishwa igipimo.

1. Hariho ibikoresho bibisi byitwa plasitike mubicuruzwa bya pulasitike, bigira uruhare runini mu kurwanya gusaza, ariko bizahinduka mu kirere, bityo iyo plasitike igabanutse, ibara rizashira, kandi na plastike ya plastike nayo izagabanuka. , bizatuma bivunika n'umuhondo.

2. Umuhondo wibisanduku bya plastike nyuma yumusaruro cyangwa gukoreshwa igihe kirekire biterwa no gusaza kwibikoresho byakoreshejwe, cyangwa birashobora gukorwa nyuma yo kwangirika.Ikintu gikomeye cyane ni udusanduku twera twa plastike yera, nkibisanduku bimwe byera byera hamwe na barrique ya plastike.

3. Impamvu isanzwe ni gusaza kwibicuruzwa bya plastiki.Impamvu nuko polypropilene ifite igitero cyo hejuru.Guhagarara kwayo ntabwo ari byiza cyane, cyane cyane mugihe cyo kumara igihe kirekire.

4. Kubwibyo, kugirango plastike yera imare igihe kirekire, gerageza wirinde urumuri rukomeye.Niba bifitanye isano nibiryo, gerageza gukoresha plastike iboneye kandi idafite ibara.Niba ushaka kurandura iki kintu, urashobora kongeramo umubare runaka wa stabilisateur yoroshye.
