Polystyrene (PS) zvinhu isarudzo yakakurumbira yekutakura tepi mbishi zvinhu nekuda kwekusiyana kwayo uye kuumbwa kwayo. Mune ino chinyorwa positi, isu tichanyatso tarisisa kuPS zvinhu zvivakwa uye tokurukura maitiro azvinoita maitiro ekuumba.
PS zvinhu ndeye thermoplastic polymer inoshandiswa mumaindasitiri akasiyana sekurongedza, zvemagetsi uye zvemotokari. Mukutakura tepi kugadzirwa isarudzo yakanakisa nekuda kwehupfumi hwayo, kusimba uye kushomeka kwekudzivirira.
Paunenge uchishandisa PS zvinhu semutakuri tepi mbishi zvinhu, zvinodikanwa kuti unzwisise maitiro ayo. Chekutanga, PS is amorphous polymer, zvichireva kuti haina inooneka crystalline chimiro. Ichi chimiro chinokanganisa maitiro ayo emagetsi uye ekupisa, kureva kuoma, brittleness, opacity uye kupisa kupisa.
Iyo yakasarudzika musanganiswa wezvivakwa zvePS zvinhu zvinoita kuti ive yakanakira indasitiri yemagetsi. Kunyanya, hunyoro hwayo hunodzivirira hunochengetedza kuchengetedzwa kwezvinhu zvemagetsi panguva yekufambisa kana kuchengetedza. Ndosaka PS zvinhu iri sarudzo yakakurumbira yekutakura tepi mbishi zvinhu.
Chimwe chinhu chakakosha chePS zvinhu kuumbwa kwayo. Nekuda kwekudzika kwayo kunyungudika viscosity, PS ine yakanakisa kuumbwa, inogonesa yepamusoro-mhando kupedzisa uye inobudirira nguva yekugadzirisa paunenge uchigadzira inotakura tepi zvinhu.
PS kuumba kuita
1. Amorphous zvinhu zvine hunyoro hushoma hunyoro, hazvidi kuomeswa zvakakwana, uye hazvisi nyore kuparara, asi ine yakakura yekuwedzera kwekushisa coefficient uye inotarisana nekushungurudzika kwemukati. Iyo ine mvura yakanaka uye inogona kuumbwa ne screw kana plunger jekiseni muchina.
2. Zvakakodzera kushandisa tembiricha yepamusoro, tembiricha yepamusoro mold, uye kushomeka kwejekiseni. Kuwedzera nguva yejekiseni kunobatsira kuderedza kushushikana kwemukati uye kudzivirira shrinkage cavity uye deformation.
3. Mhando dzakasiyana-siyana dzemasuo dzinogona kushandiswa, uye gedhi rinobatanidzwa nechikamu chepurasitiki mu arc kudzivirira kukanganisa kwechikamu chepurasitiki panguva yegedhi. Demoulding slope yakakura, uye ejection iyunifomu. Ukobvu hwemadziro echikamu chepurasitiki yunifomu, uye hapana chekuisa zvakanyanya sezvinobvira, senge Insets inofanira kunge isati yapisa.
Kupfupisa, PS zvinhu isarudzo yakanaka kwazvo yekutakura tepi mbishi zvinhu nekuda kweiyo yakasarudzika zvimiro uye kuumbwa. Se thermoplastic polymer, PS ine hupfumi, yakasimba uye inodzivirira kupisa. Pamusoro pezvo, kupikisa kwayo hunyoro kunoita kuti ive yakakodzera kuchengetedza zvinhu zvemagetsi panguva yekufambisa uye kuchengetedza.
Kunzwisisa PS zvinhu zvivakwa uye maitiro avo pakuita maitiro kwakakosha pakugadzirisa kugadzirwa kwematepi. Nekusarudza premium PS zvinhu, tinogona kugadzira matepi ekutakura emhando yakanaka uye nehunyanzvi hwepamusoro, kuve nechokwadi chekubudirira kwechero chigadzirwa chemagetsi.
