Iplastiki kunye nerabha yezakwindawo efanayo yePolymer Iqinile, inzima kakhulu kwaye ayinakukolulwa kwaye ityelwe . ubulukhuni lwerabha bungayimfuneko kwaye buya kwandiswa. ngqo . Inokugqitywa kwirabha efunyanisiweyo ngaphambi kokuba ifumaneke, ngoko ke uqonde ukuba irabha yabo isetyenziswe ngokubanzi ngenxa yeempawu zayo, okokuqala
1) Irabha ye-thermal ehleliweyo ngumqhubi wobushushu, kwaye ukuqhubela phambili kwe-{6} {~ {10} {{10} {{4} {{4} 0 Iziphumo zokufakelwa kobushushu ziya kuphuculwa ngakumbi, kwaye ukuqhubela phambili kwe-shirmal kuya kuncitshiswa kube kwi-0.4 ~ 2.0 iitts. Naziphi na iinxalenye zerabha ezisetyenzisiweyo zinokuvelisa ubushushu ngenxa yelahleko yeHysteris, ke kuya kufuneka kuthathwe ukhathalelo lokuphazamisa ubushushu.
2) Ukwanda kwe-shirmal ngenxa yomthamo omkhulu wasimahla phakathi kwenkunkuma yerabha, ukujikeleziswa kwangaphakathi njengokuyila kweqondo lemodeli ye-20 ye-{1}. 1 . 2 ~ 3 {}} i-5% yerabha ye-shrinkige ye-shrintage ye-shrintage ye-shript inobunzima obuthile . I-theoretical orkoc ye-shrinkage yeerubbege ezahlukeneyo zezi: irubber irabha> irabha ye-braber> irabha yendalo> I-Nubrene iRuble Ukuthengisa okungaphezulu kwe-250 yeedola iidola zaseMelika, iimveliso zerabha kudala ziyinto ebalulekileyo kurhwebo lwamanye amazwe. KwiMarike yeHlabathi, iimveliso zerabha zenze amathanga njengeziko, egxile kwizibonelelo zemveliso, kubandakanya neemveliso zemihla ngemihla ezinjengezihlangu zerabha kunye neetephu, kunye nezemidlalo, inkcubeko kunye nemidlalo.
