Mhando dzemapurasitiki uye zvakanakira uye zvakashata

Purasitiki ndeye monomer seyakaomeswa, kuburikidza nePolymerization kana Polycendenation Reaction yePolymer Compounds ruvara uye zvimwe zvinowedzera.

Chikamu chikuru chepurasitiki chiri resin. Resin iri polymer yakakomberedzwa iyo isisati yasanganiswa nevakawanda vanowedzera. Izwi rekuti resin rakatumidzwa zita rinotumidzwa mazita mushure mekunge lipds rakachengetedzwa nezvirimwa nemhuka, senge rosin negavakava. Resin maakaunti kweanenge 40% kusvika 100% yehuremu hwese hwepurasitiki. Izvo zvinhu zvakakosha zvevapurasitiki zvinonyanya kutsanangurwa nemhando yeiyo resin, asi zvinowedzera zvakare zvinotamba zvakakosha. Dzimwe plastiki dzakanyudzwa dzesvomukati mechigadzirwa dzesimba, dzisina kana kana vashoma vanowedzera, vakadai sema-plxiglass, nezvimwe.

Purasitiki ndeye hunyanzvi hwezvinhu zvakakosha, pane imwe tembiricha uye kumanikidzwa kwakaumbwa mune chimwe chimiro, uye pakudziya kwemakamuri kunogona kuchengetedza chimiro chakagadziriswa chePolymer zvinhu zvinhu. Mapurasitiki akajeka uye akasimba. General Fensity ye 0.9-2G3G / MM3, is 1/ 8-1 / 4 yeSimbi yekunzwa kuvhundutsa kunyudza uye kurira kushoma kuita. Mapurasitiki zvinoenderana nekuita kwekupisa kwemusoro kwakakamurwa kuita organosta ichave yakanyorwa uye iyo thermplastic purastic.

Thermosing Plastic hunhu tembiricha yakanyanya kukwirira pane yekuenda. Senge phenoiki plastics (inowanzozivikanwa seBakelite), epoxy purastics (EP) uye zvichingodaro.

Hunhu hweTheRMplastic: Kupisa shanduko mumamiriro emuviri nekunyorova kwakasimba kana kunyungudika kuita viscous fluid State, asi mushure mekutonhora uye inogona kuve yakaoma uye yakasimba, uye maitiro acho anogona kudzokororwa kazhinji. Iyo moleky chimiro cheplastiki pachayo haichinje. Senge polyethylene plastiki (pe), polyvinyl chloride purasitiki (PVC).

Kuremara kukuru kwezvigadzirwa zvepurasitiki:

1. PHI Peak : Nekuda kweiyo jekiseni paramita kana kuumbwa maererano nezvikonzero zvepurasitiki fringe, kazhinji mune yechiumbwa kuparadzaniswa kwepasi, thider, inotsvedza uye zvimwe zviitiko

2. Shrinkige: Kana iyo Plastiki inonyungudika kuburikidza neyakaonda-chikamu, iyo yekumanikidza kurasikirwa kwakakura kwazvo, zvakaoma kuchengetedza zvakanyanyisa kudzvanywa kuti uzadze muchikamu cheiyo-chikamu uye kuumbwa kwemakomba

3. Fiusion Line (mutsara wemvura) : Plastic LELT YAKAITWA MUCHINYANYA PAKATI PANDSTOCALS (CORE uye zvimwe zvinhu)

4. Ruzivo : Raw zvigadzirwa muMold Cavity inoyerera mumvura yemvura seyakaitika yegore rakatenderera mitsetse

5. Kushaikwa kweGlue (Underfill): Nekuda kwekusakwana jekiseni yekumanikidza kana kuti zvimwe zvikonzero zvekuti molen

6. Yepamusoro chena (Pamusoro Convex): Nekuda kwekusunungurwa kweMold Yemutumbi, chigadzirwa chechigadzirwa chiri pasi pekusimba kweEjection ejection uye kuburitsa machena mavara kana mabumps

7 yemugodhi anotonhorera kupfuura chikamu chekutsanya nekutsanya, iyo nzvimbo yeresin yekukanda side

8. Kupisa: Nekuda kwekusanzwisisika zvikonzero zvekupisa uye kurova

.

10. Makirogiramu: Nekuda kwekushushikana kwemukati kana manhamba ekukuvara kunokonzerwa nemakonzo kana madiki marara mune chigadzirwa, kushushikana kwekunze kana kushushikana kwekunze kana kushushikana kwemamiriro ekunze

11. Dhonza White: Kuumbwa zvigadzirwa kubva kuHook nekuda kweiyo hovensi dzehunhu hwakakura kupfuura yeEJIEChiction Simba reBar, kuitira kuti zvimwe zvikamu zvechigadzirwa chechigadzirwa

12. Chekunyama Ruva: Nekuda kwezvinhu zvakaomeswa mukuumbwa kweiyo yakazara kuoma, uye kuumbwa kwemadoti kana mitsara yematanho

13. Rwiyo rwiyo: Iyo pamusoro pechigadzirwa haina kuwirirana neiyo standard sampule ruvara
