Chii Chimiro chePolypropylene (PP)?

Zvimwe zvezvinonyanya kukosha zve polypropylene ndezvi:
1.Chemical Resistance: Diluted bases uye acids hazviiti nyore nyore ne polypropylene, iyo inoita kuti ive sarudzo yakanaka yemidziyo yezvinwiwa zvakadaro, zvakadai sekuchenesa, zvigadzirwa zvekutanga, nezvimwewo.
2.Elasticity uye Toughness: Polypropylene ichaita ne elasticity pamusoro pehumwe mutsara wekutsauka (sezvinhu zvose), asi ichaonawo kushanduka kwepurasitiki pakutanga kwekugadzirisa, saka inowanzoonekwa se "yakaoma" zvinhu.Kuomarara izwi reinjiniya iro rinotsanangurwa sekugona kwechinhu kutsvedza (purasitiki, kwete elastically) pasina kutyora.
3.Fatigue Resistance: Polypropylene inochengetedza chimiro chayo mushure mekunyanya torsion, kukotama, uye / kana kushandura.Ichi chivakwa chakakosha pakugadzira mahinji ekugara.
4.Insulation: polypropylene ine yakanyanya kupikisa magetsi uye inobatsira zvikuru kune zvigadzirwa zvemagetsi.
5.Transmissivity: Kunyange zvazvo Polypropylene inogona kuitwa pachena, inowanzobudiswa kuti ive yakasikwa yakasvibiswa muvara.Polypropylene inogona kushandiswa kumashandisirwo uko kumwe kuchinjisa kwechiedza kwakakosha kana uko kune yeaesthetic kukosha.Kana yakakwira transmissivity ichidikanwa saka mapurasitiki seAcrylic kana Polycarbonate isarudzo dziri nani.
Polypropylene inorondedzerwa se "thermoplastic" (kusiyana ne "thermoset") zvinhu zvine chekuita nemapinduriro epurasitiki pakupisa.Thermoplastic zvinhu zvinova mvura pazvinonyunguduka (zvinoita 130 madhigirii Celsius kana iri polypropylene).
Chinhu chikuru chinobatsira nezve thermoplastics ndechekuti inogona kudziyirwa kusvika pakunyunguduka kwayo, yatonhodzwa, uye kupiswa zvakare pasina kushatisa kwakanyanya.Panzvimbo pekupisa, thermoplastics yakaita sepolypropylene liquefy, iyo inovabvumira kuti vakwanise kuumbwa jekiseni nyore uye vozoshandiswazve.
Kusiyana neizvi, thermoset mapurasitiki anogona kungopisa kamwe chete (kazhinji panguva yekuumba jekiseni).Kupisa kwekutanga kunokonzera kuti thermoset zvinhu zvigadzike (zvakafanana ne 2-part epoxy) zvichikonzera shanduko yemakemikari isingagoni kuchinjwa.Kana ukaedza kupisa purasitiki ye thermoset kune tembiricha yepamusoro kechipiri yaingopisa.Hunhu uhwu hunoita kuti thermoset zvinhu zvisaite vamiriri vekudzokorodza.
