Polypropylene vs Polyethylene
Polypropylene (PP) uye polyethylene (PE) zviviri zvezvinonyanya kushandiswa thermoplastic zvinhu munyika. Kunyange vachigovana zvakawanda zvakafanana, vanewo misiyano yakasiyana inoita kuti chinhu chimwe nechimwe chikodzere zviri nani kune mamwe maapplication. Zvino ngatitarisei zvakajairika uye mutsauko nezve polypropylene vs polyethylene
Polypropylene chinhu chakasiyana-siyana chinoshandiswa mumaindasitiri akasiyana siyana, anosanganisira mota, kurongedza, uye kuvaka. Iine nzvimbo yakakwirira yekunyunguduka, iyo inoita kuti irege kupikisa kupisa uye makemikari. Icho zvakare chinhu chakareruka icho chiri nyore kugadzirisa uye kuumba. Polypropylene inozivikanwa nekusimba kwayo uye simba, izvo zvinoita kuti ive yakanaka kune maapplication uko kuoma kwakakosha.
Polyethylene, kune rumwe rutivi, inoshanduka uye yakapfava zvinhu zvinoshandiswa mumhando dzakasiyana dzekushandisa, senge kurongedza, polyethylene poda kupfeka, kurima, uye utano. Icho chinhu chakareruka chinopesana nehunyoro uye makemikari. Polyethylene zvakare yakanaka magetsi insulator, iyo inoita kuti ive yakanaka kune maapplication anoda magetsi conductivity.
Kana zvasvika kune yavo yemuviri zvivakwa, polypropylene uye polyethylene zvinosiyana munzira dzinoverengeka. Polypropylene yakaoma uye yakasimba kudarika polyethylene, iyo inoita kuti isanyanya kushanduka. Polyethylene yakapfava uye inochinja-chinja, izvo zvinoita kuti irambe ichidzivirira kukanganiswa uye isinganyanye kutsemuka. Polyethylene zvakare ine yakaderera kunyungudika pane polypropylene, izvo zvinoita kuti zvive nyore kugadzira uye kuumba.
Panyaya yemutengo, polyethylene kazhinji isingadhure pane polypropylene. Izvi zvinodaro nekuti polyethylene iri nyore kugadzira uye inoda kushoma kugadzirisa pane polypropylene. Zvisinei, mutengo wechinhu chimwe nechimwe unogona kusiyana depending pane chaiyo application uye huwandu hunodiwa.
Kana zvasvika pakukanganisa kwezvakatipoteredza, ese ari maviri polypropylene uye polyethylene anogona kushandiswazve uye anogona kushandiswa zvakare mumhando dzakasiyana dzekushandisa. Zvisinei, polyethylene inoonekwa seyakanyanya kushamwaridzana kwezvakatipoteredza kupfuura polypropylene, sezvo inogadzirwa kubva kune yakapfava chimiro chemakemikari uye inoda shoma simba kugadzira.
Muchidimbu, polypropylene uye polyethylene zviviri zvezvinonyanya kushandiswa thermoplastic zvinhu munyika. Kunyange vachigovana zvakawanda zvakafanana, vanewo misiyano yakasiyana inoita kuti chinhu chimwe nechimwe chikodzere zviri nani kune mamwe maapplication. Polypropylene inozivikanwa nekusimba kwayo uye kusimba, nepo polyethylene iri kuchinjika uye inoshingirira kukanganiswa. Pakusarudza pakati pezvinhu zviviri izvi, zvakakosha kuti utarise mashandisirwo chaiwo, zvimiro zvemuviri, mutengo, uye nharaunda.
Polypropylene vs Polyethylene
Isu tiri kutsvaga chaiyo mhando yePP resin, asi isu hatina chokwadi nezve kuumbwa kwayo chaiko uye modhi. Tinozvitenda kana iwe ukakwanisa kugamuchira muenzaniso kubva kwatiri uye kusimbisa kana iwe uchipa iyi chaiyo resin. Iwe uri mugadziri wakananga, kana iwe unoshanda semutengesi? Isu tinosarudza kubatana zvakananga nevagadziri kuchengetedza mitengo yemakwikwi uye kunyatsogadzirisa zvinodiwa zvehunyanzvi. Kana iwe uri mugadziri, iwe unopa chigadzirwa chitupa pakutumira? Pamusoro pezvo, ndokumbirawo mupe ruzivo nezve mutengo wekutengesa, uye kuendesa FOB pachiteshi muChina kunogoneka here?
Isu tinonyanya kufarira PP resin yakakodzera kunyudzwa kwepurasitiki muindasitiri yekuvaka. Kunyangwe isu takamboshandisa sampuli yeiyi PP resin, isu tinoshaya yakazara tekinoroji maratidziro uye tarasikirwa nekusangana nemupi. Parizvino, tinoda kutengwa kwepagore kwematani makumi mashanu eiyi resin yekunyudza mapurasitiki eindasitiri. Izvo zvakakosha kuti chigadzirwa chine 50% chaiyo yekuumbwa. Isu tine chinangwa chekutora diki diki yekuyedza, uye kana inoenderana neyekutanga resin sampu, isu tinoenderera mberi nekuisa odha yegore yematani makumi mashanu.
