Chii chinonzi pp chakagadzirwa? Kutarisisa kwakadzama pazvinhu uye zvikumbiro zve polypropylene (PP)
Kana zvasvika kune zvemapurasitiki zvinhu, mubvunzo wakajairika ndewePP wakagadzirwa naPPTE.PP, kana Polypropylene, polyeplastic polmer yakapararira zvakanyanya muhupenyu hwezuva nezuva uye maindasitiri ekushandisa. Munyaya ino, isu tichaongorora zvakadzama zvimiro zvemakemikari uye zvemuviri zvePP zvinyorwa uye huwandu hwayo hwakawanda hwekushandisa muminda dzakasiyana.
Chii chinonzi pp?
PP (polypropylene) Izita reChinese yePolypropylene, iri resin yakagadzirwa yakagadzirwa nePolymerisation yeProcylene Monomer. Icho ndezvemapoka epolydolefin emapurasitiki uye ndeimwe yemapurasitiri anoshandiswa kwazvo munyika. Polypropylene zvinhu zvave shongwe yakakosha yeiyo plastic indasitiri nekuda kwekuita kwavo kwakanaka kuita uye mari yakaderera mari yekugadzira.
Chemical chimiro uye zvivakwa zvePP
Kubva pane yemakemikari maonero, iyo molecular chimiro chakareruka uye chine kabhoni uye hydrogen history yekukanganisa, uye zvinoratidza zvakaringana. Hygroscopicity, iyo inoita kuti izoshandiswe zvakanyanya mumagetsi uye zvemagetsi zvinyorwa zvine zvemagetsi zvakanakisa uye zvakanyorova zvekunyorova, zvichiita kuti iwanikwe muminda yemagetsi uye yemagetsi.
Zvivakwa zvemuviri zvePP
Zvivakwa zvepanyama zvePolypropylene shandisa iyo yakasarudzika yakawanda yekuzvikudza Tembiricha dzisina kuremara.PP ine yakakwira inonyungudika pfungwa (160 kusvika pa180 ° C), iyo inoita kuti iite kuti kuishandisa mukudziya kwakanyanya pasina kuremara. deformation. Izvi zvivakwa zvemuviri zvinoita kuti pp yakakodzera pakurongedza, zvinhu zvemumba uye zvikamu zvemotokari.
Nzvimbo dzekushandisa dzePP zvigadzirwa
Nekuda kwezvivakwa zvaro zvakanaka, PP inoshandiswa mune dzakasiyana siyana dzekushandisa. Mune indasitiri yokuputika, PP inowanzoshandiswa kugadzira mabhegi epurasitiki, chikafu chezvekudya uye bhodhoro zvisizvo, zvisina kujairika, zvinopisa uye chinochengetedza chikafu chitsva kwenguva yakareba. Mune munda wekurapa, PP inoshandiswa kuita syringe zvinokatyamadza uye labware, iyo inofarirwa nemakemikari emakemikari, uye muindasitiri yemotokari, pane zvimwe zvinhu, nekuda kwezvinhu zvakanakisa zvinokanganisa uye zvakareruka.
Zvakatipoteredza hushamwari uye hunogara
Nekuwedzera kwekuziva kwekudzivirirwa kwezvakatipoteredza, zvinhu zvinokosheswa nekudzokorora kweCyclabiling
Mhedziso
Mubvunzo wezvaakagadzirwa PP hunogona kupindurwa nemakemikari nemakemikari, zvimiro zvepanyama, uye huwandu hwakawanda hwekushandisa. Kana iwe uchida mutengo-zvinobudirira uye zvinopesana kana uchisarudza zvinhu zvepurasitiki, PP pasina mubvunzo sarudzo yakanaka.
