Plastiki yerineni Ngoro: kuumbwa kwezvinhu zvakasvibirira zvezvigadzirwa zvepurasitiki
Raw zvinhu kugadzira matanho epurasitiki zvigadzirwa zvepurasitiki rineni Ngoro:
1. Mapurasitiki anowanzoshandiswa anosanganisira poly (vinyl chloride) (PP), poly (vinyl chloride) (polyethylene glycol) (PVC), poly (vinyl chloride) (polyethylene glycol) (PVC), nezvimwewo.
2. Mafirita anogona kuvandudza kusimba uye kupisa kupisa kwemapurasitiki uye kuderedza mutengo.Inowanzoshandiswa ipfu yehuni, fiber yemiti, girazi fiber, diatomite, asbestos, carbon black, etc. Plasticizers inogona kuwedzera plastiki uye kupfava kwepurasitiki.Phthalates inowanzoshandiswa.
3. Iyo stabilizer yengoro yerineni yepurasitiki ndeyekudzivirira kuparara uye kukanganisa kwe synthetic resin nekuita kwechiedza uye kupisa.Stearate uye epoxy resin inowanzoshandiswa.
4. Iyo colorant yengoro yerineni yepurasitiki inoita kuti plastiki ive nemavara akasiyana.Organic dhayi uye inorganic pigments inowanzoshandiswa.
5. Mafuta anoita kuti mapurasitiki asanamatira kune mold panguva yekugadzira nekugadzira, uye inoita kuti nzvimbo yepurasitiki iite zvakanaka uye yakanaka.Calcium, magnesium uye mamwe masimbi emunyu e stearic acid anowanzoshandiswa.
Kune iyo inotenderera yekuumba inofa iyo yave mukugadzira uye kushandiswa, kunyangwe kuchengetedza kwezuva nezuva kwekufa kuri panzvimbo kunobata zvakananga kunaka kwezvinotenderera zvigadzirwa zvekuumba uye hupenyu hwebasa hwefa.Nekudaro, mukugadzirwa kwekutenderera kuumbwa, vazhinji vanoshanda vanofuratira kuchengetedzwa kweanotenderera mold mold nekuda kwekushaikwa kweruzivo rwakakodzera rwekuchengetedza, zvichikonzera kukanganisa kwemhando yechigadzirwa uye mold uye kurasikirwa kusingakoshi kumabhizinesi.Naizvozvo, kutarisisa kwakazara kunofanirwa kubhadharwa kune kuchengetedza kwezuva nezuva kwe mold, uye zvinotevera zvinhu zvinofanirwa kuitwa nekuchenjerera:
1. Kazhinji cherechedza mamiriro ezvigadzirwa kana molds kuti uone kana pane zvikwangwani, concave, peeling, kuputika uye mamwe mamiriro.Kana madiki madiki mapoinzi anowanikwa pamusoro peiyo mold cavity, anofanirwa kugadziriswa nenguva;
2. Pakunamatira mold, usazviita zvisina hanya.Pry iyo yakaoma nematanda uye zvimwe zvinhu, kunyanya simbi yesimbi, iyo iri nyore kukuvadza mold.Kune mold yakanamirwa neTeflon, kana chidimbu chidiki chachekwa uye chakafukunurwa, chinobviswa nefoshoro uye chakapfapfaidzwa zvakare, zvichikonzera matambudziko uye kunonotsa kugadzira uye nguva yekutumira.Naizvozvo, isu tinofanira kuedza nepatinogona napo kusarudza inochinjika uye yakapfava demoulding kurapwa nzira.Isu tinosarudza kunonoka, asiwo pane chirevo chekusakuvadza mukati megomba remuumbi.
3. Kana pane mavanga kana burrs pane mold, haigoni kugadziriswa nefaira, asi inogona kungoputirwa nemafuta akaisvonaka kana gauze yakanaka.
4. Kuwedzerwa kwemarara kunowanzo kuunganidza zvakapoteredza flange ye mold, iyo inofanira kucheneswa munguva kuti ivimbise kuiswa chisimbiso chekugadzira.Zvisinei, teerera kushandiswa kwebamboo banga kana tsvimbo yepurasitiki panguva yekuchenesa, uye usashandise zvishandiso zvakasimba sesimbi banga, kuitira kuti usakuvadza nzvimbo yekuparadzanisa yeflange.
5. Iyo mold ichaiswa munzvimbo yakaoma uye inofefetera kudzivirira kupinda kwemhute yemvura kusakanganisa kugadzirwa uye kunaka kwechigadzirwa.Iise pasi uye inotakura-kutakura.Tarisa uone kana mold base yakatsemuka uye yakakuvadzwa.Iyo mold inofanira kuiswa patsva uye kuiswa kudzivirira deformation nekuda kwekuremerwa kwayo.
6. Tarisa uone kana mhepo isina kuvharwa uye yakavharwa;Tarisa uone kana mabhaudhi ekusunga, zvitubu uye mabhaudhi ane simba uye akasununguka.
7. Mushure mekupedza basa rekugadzira, bvisa mold kubva kumuchina wekutenderera unotenderera munguva uye uiise panzvimbo yakadzika.Kuti udzivise deformation ye mold uye yakareba-yakareba unilateral mutoro weinotenderera yekuumba midziyo inokonzerwa nekumira kwakamira kweiyo mold pamushini unotenderera wekuumba kwenguva yakareba, izvi zvinonyanya kukosha kune yakakura, yakareba mitsetse uye inorema inotenderera inoumba molds.
