PP yakagadzirwa nei? Kutarisisa kwakadzama kwezvivakwa uye mashandisirwo epolypropylene (PP)
Kana zvasvika kune zvepurasitiki zvinhu, mubvunzo wakajairika ndewekuti chii PP yakagadzirwa.PP, kana polypropylene, i thermoplastic polymer iyo yakanyanya kuwanda muhupenyu hwemazuva ese uye maindasitiri ekushandisa. Muchinyorwa chino, isu tichaongorora zvakadzama kemikari uye zvemuviri zvimiro zvePP zvinhu uye huwandu hwayo hwakawanda hwekushandisa muminda dzakasiyana.
Chii chinonzi PP?
PP (Polypropylene) zita rechiChinese repolypropylene, iresin yekugadzira inogadzirwa ne polymerization yepropylene monomer. Ndecheboka repololefin remapurasitiki uye nderimwe remapurasitiki anonyanya kushandiswa pasi rose. Polypropylene zvinhu zvave mbiru yakakosha yeindasitiri yemapurasitiki nekuda kwekuita kwavo kwakanaka uye mutengo wakaderera wekugadzira.
Kemikari chimiro uye zvimiro zvePP
Kubva pamakemikari ekuona, chimiro chemolecular yePP chiri nyore uye chine kabhoni nehydrogen maatomu.PP ine mutsara dhizaini ine akawanda propylene mayunitsi mu molecular chain, uye chimiro ichi chinopa iyo yakanaka makemikari kuramba uye kugadzikana.PP zvinhu hazvina mbiri zvisungo, uye nekudaro inoratidza yakakwira kuramba kune oxidation, asidhi uye alkali nharaunda.PP inogadzira iyo yakanakisa magetsi emagetsi uye yakaderera kushandiswa kwemagetsi. zvinhu zvine yakanakisa kuvharirwa kwemagetsi uye kunyura kwakadzika, zvichiita kuti ishandiswe zvakanyanya mundima dzemagetsi nemagetsi.
Zvinhu Zvenyama zvePP
Zvinhu zvemuviri zvepolypropylene zvinotarisa kushandiswa kwayo mune zvakasiyana-siyana zvekushandiswa.PP ine chiyero chepamusoro chekristallini, chinoita kuti chive chakasimba uye chakasimba.PP ine yakaderera density (inenge 0.90 kusvika 0.91 g / cm³), iyo ndeimwe yepasi pasi pakati pepurasitiki, zvichiita kuti zvigadzirwa zvePP zvive zvishoma. tembiricha isina kuremara.PP ine nzvimbo yakakwira yekunyungudika (160 kusvika 170°C), izvo zvinoita kuti zvikwanise kuishandisa mukupisa kwepamusoro pasina kuremara. deformation. Izvi zvimiro zvemuviri zvinoita kuti PP yakanakira kurongedza, zvinhu zvemumba uye zvikamu zvemotokari.
Nzvimbo dzekushandisa dzePP zvinhu
Nekuda kwehunhu hwayo hwakanaka, PP inoshandiswa mumhando dzakasiyana dzekushandisa. Muindasitiri yekurongedza, PP inowanzoshandiswa kugadzira mabhegi epurasitiki, kurongedza chikafu uye mabhodhoro mavharo nekuti haina chepfu, haina kunhuwa uye inochengeta chikafu chitsva kwenguva yakareba. Muchikamu chekurapa, PP inoshandiswa kugadzira majekiseni uye labware anoraswa, ayo anofarirwa nekuramba kwemakemikari uye yakanaka sterilization zvivakwa, uye muindasitiri yemotokari, uko inoshandiswa kugadzira mukati memukati mabhampa uye mabumpers, pakati pezvimwe zvinhu, nekuda kwekunaka kwayo kupikisa uye huremu zvivakwa.
Kunoshamwaridzana Nezvakatipoteredza uye Kunogarisa
Nekuwedzera kwekuziva kwekuchengetedzwa kwezvakatipoteredza, zvinhu zvePP zvinokosheswa nekuda kwekugadzirisa zvakare.Zvigadzirwa zvePP zvinogona kudzokororwa uye kushandiswa zvakare kuburikidza ne mechanical recycling kana makemikari recycling, kuderedza mutoro pane zvakatipoteredza.PP's low carbon emissions uye zvinhu zvinoparara zvinoitawo kuti ive mumiriri akasimba kune ramangwana eco-friendly materials.
Mhedziso
Mubvunzo wekuti PP inogadzirwa nei inogona kupindurwa zvakakwana kuburikidza nekugadzirwa kwayo kwemakemikari, maitiro emuviri, uye zvakasiyana-siyana zvekushandiswa.PP iri kuita basa rinokosha munhamba iri kukura yemaindasitiri sechinhu chine hupfumi, chakasimba, uye chinochengetedza zvakatipoteredza. Kana iwe uchida mutengo-kushanda uye kuita zvakasiyana-siyana pakusarudza zvinhu zvepurasitiki, PP pasina mubvunzo isarudzo yakanaka.
