Isu tese tinoziva kuti mapurasitiki mazhinji ari nyore kuburitsa carcinogens mushure mekupisa, inokanganisa hutano hwevanhu, polypropylene, PP plastiki ndiyo yakanyanya kupisa kupisa mumapurasitiki makuru mashanu.Inoshandiswa zvakanyanya mukugadzira chikafu.Plastiki inopisa ne microwave oven.
Polypropylene, inonzi PP kwenguva pfupi, inogadzirwa zvakanaka thermoplastic synthetic resin ine isina ruvara, isina kunhuhwirira, isina -chepfu, translucent yakasimba zvinhu, diki density uye chiedza: PP ndiyo yakanyanya density epurasitiki raw material, ine density ye 0.89 chete. ~ 0.91g/cm (idiki pane mvura)
Kupisa kwakanaka kwekupisa: Muzhinji mapurasitiki, PP plastiki ndiyo yakanyanya kupisa kupisa, uye kupisa kwayo deformation tembiricha ndeye 80-100 ° C. Inogona kubikwa mumvura inopisa.
Kuomarara kwakanaka: PP plastiki ine kuramba kwakanaka kune kutsemuka, pamwe nehupamhi hwekukotama hupenyu hwekuneta, izvo zviri nyore kuumba.
Chemical kuramba: PP plastiki inogona kuramba asidhi, alkali, munyu mhinduro uye akasiyana organic solvents pazasi 80 ° C, uye inogona kuora pasi pekupisa kwakanyanya uye oxidation mhedzisiro.
Panguva imwecheteyo, PP plastiki zvakare ine magetsi ekudzivirira, yakakwira-intensity mechanical zvivakwa uye yakanaka yakakwirira-kupfeka -resistant kugadzirisa zvivakwa.
Izvo zvakashata zvePP plastiki: kuderera kwehukuru hwaro, kusakwana kuomarara, kushomeka kwemamiriro ekunze, uye "kukuvadza kwemhangura".Iine post-contraction phenomenon.
Seimwe yeashanu makuru epurasitiki epurasitiki, PP Plastic inoshandiswa zvakanyanya muhupenyu hwezuva nezuva:
A. Nzvimbo yeindasitiri yemotokari:PP ine simbi yekuwedzera: mapedhi, pombi dzemhepo, mafeni, nezvimwe.
B Kugadzira Pamba:
C bhokisi rekuchengetedza rakachena
D mudziyo / chisimbiso mudziyo
Semugadziri wetsikazvigadzirwa zvepurasitiki uye molds, unogona kusangana nezvakawanda zvinodiwa muZhongda.Kana iwe uchida kwatiri, tapota taura nesu chero nguva.
