Iyo mbishi yepurasitiki ndeye synthetic resin, inobviswa uye inogadzirwa kubva mupetroleum, gasi rechisikigo kana marasha kuparuka.Oiri, gasi rechisikigo, nezvimwewo zvinoodzwa kuita yakaderera-molecular organic komisheni (senge ethylene, propylene, styrene, ethylene, vinyl doro, zvichingodaro), uye iyo yakaderera-mamorekuru komisheni inoumbwa kuita yakakwira-molecular organic compounds pasi pemamwe mamiriro. , uyezve plasticizers, Lubricant, fillers, etc., anogona kugadzirwa akasiyana epurasitiki mbishi zvinhu.Kazhinji, resin inogadziriswa kuita granules kuitira nyore kushandisa.Anowanzo kuumbwa kuita midziyo ine mamwe maumbirwo pasi pekudziya uye kumanikidzwa mamiriro.
Zvenyama zvimiro zvepurasitiki.Kune akawanda marudzi emhando yezvigadzirwa zvepurasitiki, zvinotevera ndizvo zvishoma zvinoda kunzwisiswa pakudzidza tekinoroji ye toning:
1. Relative density: Relative density ireshiyo yehuremu hwesample kuhuremu hwehuwandu hwemvura pane imwe tembiricha, uye inzira yakakosha yekuziva zvinhu zvakabikwa.
2. Mwero wekunyudzwa kwemvura: Yepurasitiki mbishi inogadzirwa kuita sampuli yehukuru hwakatarwa, yakanyudzwa mumvura yakanyungudutswa ine tembiricha ye (25±2) ℃, uye chiyero chehuwandu hwemvura inotorwa nesample kune iyo mbishi. mushure memaawa makumi maviri nemana.Saizi yekunyura kwemvura inosarudza kana iyo yepurasitiki yakasvibirira inoda kubikwa uye urefu hwenguva yekubika.
3. Tembiricha yekuumbwa: Tembiricha yekuumbwa inoreva kunyungudika kwekushisa kweresin mbishi
4. Decomposition tembiricha: The decomposition tembiricha inoreva tembiricha iyo macromolecular cheni yepurasitiki inotsemuka kana ichipisa, uye zvakare chimwe chezviratidzo zvekuratidza kupikisa kupisa kwepurasitiki.Kana tembiricha yekunyunguduka ichipfuura tembiricha yekuora, mazhinji emidziyo inoshanduka yero, kunyange yakatsva uye yakasviba, uye kusimba kwechigadzirwa kuchaderedzwa zvakanyanya.
