Ndeupi musiyano pakati pegum nepurasitiki?

Ndeupi musiyano pakati pegum nepurasitiki?Plastiki nerabha zvine misiyano yakakura mumasikirwo, inonyanya kuratidzwa murudzi rwe deformation, elasticity, molding process uye zvimwe zvinhu zvitatu:

(1) Deformation type: kana ichiiswa pasi pesimba rekunze, deformation yepurasitiki ichaitika, kureva kuti, hazvisi nyore kudzokera kune chimiro chepakutanga kana nyika;Iyo rabha ichapinda elastic deformation, ndiko kuti, inogona kukurumidza kudzokera kune yayo yekutanga mushure mekubvisa simba rekunze.

(2) Elasticity: Iyo elasticity yemapurasitiki kazhinji idiki, uye kugona kwayo kudzoreredza mushure mekushanduka haina simba pane iyo yerabha.Mumamiriro ezvinhu akajairwa, chiyero chepurasitiki chepasi pasi pe100%, uye elastic rate yerabha inogona kusvika 1000% kana kupfuura.

(3) Molding process: plastiki mukugadzira nzira, kana kugadziriswa kwapera, chimiro chayo chakanyatsogadziriswa, zvakaoma kuchinja;Iyo rabha inodawo kupinda mukati meiyo vulcanization maitiro mushure mekugadzira, kuitira kuti chimiro chemakemikari yerubha chiwedzere kugadzikana uye kuita kuri nani.

Pamusoro pemisiyano iri pamusoro pamasikirwo, pane misiyano mitatu pakati pegum nepurasitiki:

(1) Kuumbwa uye kunobva: plastiki inonyanya kushandiswa kubva kumafuta emafuta akadai se petroleum uye chinhu chakagadzirwa nevanhu;Gum, kune rumwe rutivi, ndeyechisikigo, inotorwa kubva kune exudates kubva mumiti yakasiyana-siyana.

(2) Zvimiro zvemuviri: chingamu kazhinji ine imwe viscosity uye elasticity, nepo mapurasitiki anogona kunge aine akasiyana emuviri zvimiro zvakaita sekupfava, kuoma uye brittleness zvichienderana nemhando chaiyo.

(3) Shandisa: Nemhaka yehusikirwo hwayo hwechisikigo uye elasticity, gum inowanzoshandiswa pakubatanidza, kuisa chisimbiso nezvimwe zvinangwa;Iko kushandiswa kwemapurasitiki kwakakura kwazvo, sekurongedza, zvekuvaka, zvigadzirwa zvemagetsi uye zvichingodaro.

Muchidimbu, mapurasitiki nerabha zvine misiyano yakakura mumhando yedeformation, elasticity, molding process, nezvimwewo, nepo chingamu nepurasitiki zvakanyanyosiyana mukuumbwa uye kunobva, zvimiro zvemuviri uye mashandisiro.Misiyano iyi inotibvumira kusarudza zvinhu zvakakodzera maererano nezvatinoda muhupenyu hwezuva nezuva uye kugadzirwa kwemaindasitiri.Kuti uwane rumwe ruzivo nezve "Musiyano pakati pegum nepurasitiki", zvinokurudzirwa kubvunza ruzivo rwakakodzera kana kubvunza nyanzvi yesainzi.
