Kubva pamaonero epfungwa:
PC (Polycarbonate): Iyi ipurasitiki isina ruvara, inoonekera uye inoyevedza uye yakatsetseka. Nekuda kwehunhu hwayo husina chepfu uye husina hwema, pamwe nehukuru hwayo hwekudzivirira UV uye hunodzivirira hunyoro, PC ine tembiricha yakakura. Inoramba isingatyoki pa -180°C uye inogona kushandiswa kwenguva refu pa130°C, zvichiita kuti ive chinhu chakanakira kurongedza chikafu.
PET (Polyethylene Terephthalate) : Ichi chinhu chakasimba kwazvo, chisina ruvara, uye chinoonekera uye chakasimba zvikuru. Chine chitarisiko chakaita segirazi, hachina hwema, hachina kunaka, uye hachina chepfu. Chinobvira moto, chinoita kuti murazvo weyero uve nemucheto webhuruu kana wapiswa, uye chine hunhu hwakanaka hwekudzivirira gasi.
Kubva pamaonero ehunhu uye mashandisirwo:
PC: Inodzivirira kukuvadzwa zvakanyanya uye iri nyore kuumbwa, zvichiita kuti ikwanise kugadzirwa mumabhodhoro, majagi, uye magadzirirwo akasiyana-siyana emagaba ekurongedza zvinwiwa zvakaita sezvinwiwa, doro, nemukaka. Dambudziko guru rePC nderekuti inogona kupwanyika nestress. Kuti izvi zvisaitike panguva yekugadzira, zvinhu zvakachena zvakanyanya zvinosarudzwa, uye mamiriro akasiyana-siyana ekugadzirisa anodzorwa zvakanyanya. Pamusoro pezvo, kushandisa maresini ane stress shoma yemukati, senge polyolefins diki, nylon, kana polyester yekusanganisa melt, kunogona kuvandudza zvakanyanya stress yayo nestress cracking uye kunyudzwa kwemvura.
PET: Ine coefficient yakaderera yekuwedzera uye chiyero chidiki chekuumba che0.2% chete, chinova chikamu chimwe mugumi chepolyolefins uye chakaderera pane PVC nenylon, zvichikonzera saizi dzakagadzikana dzezvigadzirwa. Simba rayo remuchina rinoonekwa serakanakisa, rine hunhu hwekuwedzera hwakafanana nealuminium. Simba rekudhonza remafirimu ayo rakapetwa kapfumbamwe pane polyethylene uye katatu pane polycarbonate nenylon, nepo simba rayo rekurova rakapetwa katatu kusvika kashanu pane remafirimu akajairwa. Pamusoro pezvo, mafirimu ayo ane hunhu hwekudzivirira hunyoro uye hwekuchengetedza hwema. Zvisinei, pasinei nezvakanaka izvi, mafirimu epolyester anodhura zvakanyanya, akaoma kupisa, uye anowanzo shandiswa nemagetsi asingachinji, ndosaka asingawanzo shandiswa ega; anowanzo sanganiswa nemaresini ane hunhu huri nani hwekupisa kuti agadzire mafirimu akasanganiswa.
Saka, mabhodhoro ePET anogadzirwa achishandisa nzira yekuumba mabhodhoro maviri anogona kushandisa zvizere hunhu hwePET, achipa kujeka kwakanaka, kupenya kwepamusoro, uye chitarisiko chakafanana negirazi, zvichiita kuti ave mabhodhoro epurasitiki akakodzera kutsiva mabhodhoro egirazi.
