Matambudziko akajairika mukugadzirwa kwePU kutevedzera matanda zvigadzirwavari:1. Epidermal bubbles:Mamiriro ekugadzira aripo aripo, asi kune matambudziko mashoma.2. Epidermal white line:Dambudziko riri mumamiriro ezvinhu ekugadzirwa kwemazuva ano nderekuti ungaderedza sei mutsara wakachena uye kugadzirisa nzvimbo iyo mutsara wakachena unooneka.3. Kuoma kweganda:Zvinoenderana nezvinodiwa zvakasiyana zvevatengi, parizvino hapana chiyero chaicho.Ongororo yenyaya dziri pamusoro ndeiyi: 1. Epidermal bubbles:Zvichienderana nenzvimbo uye chiitiko, zvikonzero zvakasiyana.Zvikonzero zvakajairika ndezvi:(1) Matambudziko nepfuti dzinobuda furo:a.Inogadzirwa panguva yekusanganisa maitiro: edza kudzikisa mabhuru anogadzirwa kana furo rinoyerera richibuda mumusoro wepfuti, senge kusakanganiswa kusanganisa uye kubuda kwemhepo kubva mumusoro wepfuti.b.Kusanganisa kumhanya (kumichina yakaderera yekumanikidza): iyo yakakwira kumhanya, zvirinani, uye kudiki kuyerera, zviri nani.c.Usasasa maswe pachigadzirwa.d.Iyo tembiricha yezvinhu yakakwira, mhinduro inokurumidza, uye mabhubhu achaderedzwa (kunyanya munguva yechando).e.Chiyero chemavara madema chakakwirira, mabhubhu emhepo anowedzera, uye kumanikidzwa kwetangi rekuchengetedza kunoramba kwakagadzikana.f.Tsvina neguruva zvinosanganiswa mumusoro wepfuti unopupuma.(2) Kupesvedzera kwe mold:a.Kupisa kwekuumbwa kwakakwirira, mabhubhu achaderedzwa.b.Mold exhaust effect, inonzwisisika inclination angle.c.Iyo mold chimiro inotarisa kuti zvimwe zvigadzirwa zvakawanda, uye zvimwe zvigadzirwa zvishoma.d.Mold pamusoro kutsvedzerera uye mold pamusoro kuchena.(3) Kudzora maitiro:a.Mhedzisiro yekukwesha uye kwete kubhurasha, yakawanda jekiseni uye mashoma mabhuru.b.Kunonoka kuvhara mold kunoderedza mhepo inoputika.c.Nzira yejekiseni uye kugoverwa kwezvinhu zvakasvibirira mukati me mold.(4) Pesvedzero yemumiririri wekuburitsa:a.Silicone mafuta ekuburitsa mumiriri ane mamwe mabhubhu uye mashoma waxy mabhuru2. Dambudziko remutsetse muchena wechigadzirwa epidermis:Kana iyo mbishi yaiswa mu mold, pachave nemusiyano wenguva, saka pachave nemusiyano wenguva apo iyo mbishi inotanga kuita, kuitira kuti mitsetse michena iumbwe pane yakavharika chikamu cheiyo interface pamberi uye mushure meiyo. reaction.Zvikonzero zvikuru zveizvi ndezvi: ⑴Dambudziko rekuumbwa:a.Kana tembiricha yekuumbwa iri 40-50 ℃, mutsara muchena unoderera.b.Iko kutaridzika kwekona ye mold yakasiyana, uye nzvimbo yemutsara wakachena yakasiyanawo.c.Tembiricha yemuno yemold yakakwira zvakanyanya, zvichiita kuti pave nenguva dzakasiyana dzekuita kwezvakagadzirwa, zvichikonzera mitsetse michena.d.Kana chigadzirwa chacho chakanyanya kukura kana chakanyanyisa, mutsara wakachena uchawedzera.e.Iyo mold ine chikamu chemvura yakasvibiswa uye iyo yekuburitsa mumiriri haina kuoma, zvichikonzera mitsetse michena.⑵ Pfuti inopupuma:a.Kupisa kwepamusoro kwezvinhu kuchaderedza mutsara wakachena, uye nzvimbo iyo mutsara wakachena unoonekwa apo chikamu chemavara madema chakanyanya kuoma.b.(Low pressure machine) Iyo yakanyanya kumhanya yemusoro wepfuti, iyo yekusanganisa mhedzisiro yakanaka, uye muchena mutsara uchaderedzwa.c.Pachave nemitsetse yakachena kumusoro uye muswe wezvinhu.(3) Kudzora maitiro:a.Kuwedzera kwehuwandu hwekupinza zvinhu zvakasvibirira kunoderedza mutsara wakachena.b.Mushure mejekiseni, kukwesha kunoderedza mitsetse michena.3. Kuoma kwechigadzirwa:a.Kuwanda kwezvinhu zvakasvibirira zvakakwirira, kuoma kwechigadzirwa kunowedzera, asi kuwanda kwekupinza kunowedzera.b.Chiyero chezvinyorwa zvitema zvakakwirira.Epidermal kuoma kunowedzera.c.Kana tembiricha yekuumbwa uye tembiricha yezvinhu zvakakwirira, kuoma kwechigadzirwa kunoderera.d.Mushandi wekusunungura achaderedza kuoma kweganda, uye in-mold pende inowedzera kuoma kweganda.Zvigadzirwa zvinofanirwa kudzorwa maererano nemidziyo, zvigadzirwa, maitiro, mold, nezvimwe, saka zvinokurudzirwa kutsvaga kubatana kubva kune vanopa michina ye polyurethane mukugadzira.
