Isesengura ryubumenyi bwubuzima bwa PP, PC, PS, Icupa ryamazi ya Tritan
Amacupa yamazi ya plastike arashobora kugaragara ahantu hose mubuzima.Amacupa yamazi ya plastike arwanya kugwa, byoroshye kuyatwara, kandi muburyo bwiza, kuburyo abantu benshi bakunda guhitamo amacupa yamazi ya plastike mugihe baguze amacupa yamazi.Mubyukuri, abantu benshi ntibazi ibikoresho byamacupa yamazi ya plastike, kandi mubisanzwe ntibita kumurongo hamwe numutekano wibikoresho byamacupa yamazi, kandi akenshi birengagiza umutekano wibintu byamacupa yamazi.
Ibikoresho bisanzwe kumacupa yamazi ya plastike ni Tritan, PP plastike, plastike ya PC, plastike ya PS.PC ni polyakarubone, PP ni polypropilene, PS ni polystirene, naho Tritan ni igisekuru gishya cyibikoresho bya copolyester.
PP ni kimwe mu bikoresho bya pulasitiki bifite umutekano muri iki gihe.Irashobora kwihanganira ubushyuhe bwinshi kandi irashobora gushyukwa mu ziko rya microwave.Ifite ubushyuhe bwiza cyane, ariko ntabwo bukomeye, byoroshye kumeneka, kandi bifite umucyo muke.
Ibikoresho bya PC birimo bispenol A, izasohoka iyo ihuye nubushyuhe.Gufata igihe kirekire cya bisphenol A bizatera ubuzima bwabantu.Ibihugu bimwe nakarere byagabanije cyangwa bibuza PC.
Ibikoresho bya PS nibikoresho bifite umucyo mwinshi cyane hamwe nuburabyo bwo hejuru.Biroroshye gucapa, kandi birashobora kuba amabara mubwisanzure, nta mpumuro nziza, uburyohe, ntabwo ari uburozi, kandi ntibitera gukura kw'ibihumyo.Kubwibyo, yabaye kimwe mubikoresho bya plastiki bizwi cyane.
Ababikora bahura nigitutu cyubuzima no kurengera ibidukikije kandi bashaka ibikoresho bishobora gusimbuza PC.
Muri aya masoko, Eastman wo muri Amerika yateje imbere igisekuru gishya cya copolyester Tritan.Ni izihe nyungu zayo?
1. Kwinjira neza, kohereza urumuri> 90%, igihu <1%, hamwe na kirisiti isa na kirisiti, icupa rya Tritan rero rirasobanutse neza kandi risobanutse nkikirahure.
2. Kubijyanye no kurwanya imiti, ibikoresho bya Tritan bifite inyungu zuzuye, bityo amacupa ya Tritan arashobora guhanagurwa no kwanduzwa hamwe n’imiti itandukanye, kandi ntibatinya ruswa.
3. Ntabwo irimo ibintu byangiza kandi yujuje ibisabwa byo kurengera ibidukikije n’ubuzima;gukomera gukomeye, imbaraga zikomeye;ubushyuhe bwo hejuru burwanya hagati ya 94 ℃ -109 ℃.
