Kune marudzi akasiyana-siyana emakapu emvura epurasitiki, uye hazvidzivisiki kuti isu tichave takapenya pakusarudza makapu emvura epurasitiki.
Kuti munhu wese azive zvakawanda nezvemakapu emvura epurasitiki uye kuti akwanise kusarudza aanofarira epurasitiki makapu emvura, regai nditarise kukuzivisai mutsauko uripo pakati pePC nePP mune zvepurasitiki mvura mukombe zvinhu.
PC ndiyo chidimbu cheChirungu che polycarbonate, imwe yemapurasitiki akajairika.Nyaya iyi haina chepfu uye inonyanya kushandiswa kugadzira mabhodhoro evana, makapu emuchadenga, nezvimwewo. Nekuti ine bisphenol A, zvave zvichinetsa.
Muchirevo, chero bedzi 100% yebisphenol-A inoshandurwa kuva chigadziro chepurasitiki panguva yekugadzira polycarbonate, zvinoreva kuti hapana bisphenol-a mune chigadzirwa zvachose, uye hapana ngozi kune utano.Nekudaro, kana zvidiki zveBPA zvikasashandurwa kuita chimiro chepurasitiki chepolycarbonate, inogona kuburitswa kuita chikafu kana zvinwiwa, zvichityisidzira hutano nekuchengetedzeka kwevashandisi, kunyanya vechidiki.
PP ndiyo chidimbu cheChirungu che polypropylene uye ine yakanaka yekupisa kupisa.Chigadzirwa chacho chinogona kuitwa sterilized patembiricha iri pamusoro pe100 madhigirii celsius uye hachizokanganisa pa150 degrees Celsius pasina simba rekunze.
Polypropylene imwe yemapurasitiki anonyanya kushandiswa mumavheni ewa microwave.Zvisinei, mushure mokunyatsoongorora, tichaona kuti polycarbonate pamusika inowanzodhura kupfuura zvigadzirwa zvepolypropylene, uye vatengi vanowanzotevedzera pfungwa ye "inodhura, zviri nani kunaka".Muchokwadi, musiyano wemutengo ndewekuti mutengo wazvino wetani yepolycarbonate pamusika wakakwira zvakanyanya kupfuura mutengo wetani yepolypropylene.
Tichienzanisa zvinhu zviviri izvi, zvinogona kuwanikwa kuti polypropylene yakanyanyisa kupfeka kuramba kupfuura polycarbonate, saka kana uchigadzira makapu akajeka, polycarbonate inowanzo shandiswa sechinhu.Zvigadzirwa zvepolycarbonate zvakanakisa kupfuura zvigadzirwa zvepolypropylene.Nekudaro, kubva pakuona kwekuchengetedza, tembiricha yekugadzira polypropylene plastiki inosvika 170 ~ 220 degrees Celsius, saka mvura inopisa haigone kuiparadza, saka polypropylene yakachengeteka kupfuura polycarbonate.
