Zamakono
Mitundu ya zida zapulasitiki zowonekera zomwe zimagwiritsidwa ntchito pamsika ndi: polymethyl methacrylate (acrylic kapena plexiglass PMMA pulasitiki), polycarbonate (pulasitiki ya PC), polyethylene terephthalate (PET), nayiloni yowonekera, AS (Acrylonitrile-styrene copolymer) etc. mapulasitiki atatu omwe timakumana nawo kwambiri ndi PMMA, PC ndi AS.
1. Zomwe zimapangidwira mapulasitiki owonekera: choyamba, mapulasitiki owonekera ayenera kukhala owonekera kwambiri, ndipo kachiwiri ayenera kukhala ndi mphamvu zina ndi kuvala kukana, kukana mphamvu, kukana kutentha, kukana mankhwala, ndi kuyamwa madzi.Ikagwiritsidwa ntchito, imakwaniritsa zofunikira zowonekera komanso imakhala ndi magwiridwe antchito okhazikika.
2. Makhalidwe a ndondomeko ya PMMA.PMMA ili ndi kukhuthala kwakukulu komanso kusayenda bwino kwamadzi.Chifukwa chake, kutentha kwakuthupi ndi kuthamanga kwa jekeseni kuyenera kugwiritsidwa ntchito popanga jakisoni.Mphamvu ya kutentha kwa jekeseni ndi yayikulu kuposa kuthamanga kwa jekeseni, koma kuwonjezereka kwa mphamvu ya jakisoni kumathandizira kuchepetsa kuchuluka kwa mankhwalawa.Kukana kopanda mphamvu, kukana kuvala bwino, kosavuta kukanda, kosavuta kunjenjemera, kotero kutentha kwa nkhungu kuyenera kuonjezedwa, ndikuwongolera njira yowongolera kuti igonjetse zolakwika izi.
3. Njira makhalidwe a PC.PC ili ndi kukhuthala kwakukulu, kutentha kwakukulu kosungunuka komanso kusayenda bwino kwamadzi, ndipo kupanga kwake sikuli bwino ngati PMMA.Kuthamanga kwa jekeseni sikukhudza kwambiri madzi, koma chifukwa cha kukhuthala kwakukulu, kupanikizika kwa jekeseni kumakhalabe kwakukulu.Momwemonso, pofuna kupewa kupsinjika kwamkati, nthawi yogwira mwamphamvu iyenera kukhala yayifupi momwe mungathere.Mlingo wa shrinkage ndi waukulu, kukula kwake kumakhala kokhazikika, koma kupsinjika kwa mkati mwa mankhwalawa ndi kwakukulu, ndipo n'kosavuta kusweka.
4. Makhalidwe a ndondomeko ya PET.Kutentha kwa PET ndikwambiri, ndipo kusintha kwa kutentha kwa zinthu kumakhala kocheperako (260-300 ° C), koma kusungunuka, kumakhala ndi madzi abwino, kotero kupanga kwake kumakhala kosauka, ndipo nthawi zambiri kumafunika kuwonjezera zida zotsutsana ndi kufalikira mu mphuno.Mphamvu zamakina ndi magwiridwe antchito sizokwera pambuyo pa jekeseni, ndipo ntchitoyo iyenera kukonzedwa bwino kudzera mu njira yotambasula ndikusintha.
