Daban-daban kaddarorin na robobi sun ƙayyade amfani da shi a cikin masana'antu.Tare da ci gaban fasaha, bincike kan gyaran filastik bai tsaya ba.Menene babban halayen robobi?
1. Yawancin robobi suna da haske a nauyi, sinadarai suna da ƙarfi, kuma ba za su yi tsatsa ba;
2. Kyakkyawan juriya mai tasiri;
3. Yana da kyau nuna gaskiya da juriya;
4. Kyakkyawan rufi da ƙananan ƙarancin thermal;
5. Tsarin tsari na gaba ɗaya da launi suna da kyau, kuma farashin sarrafawa yana da ƙasa;
6. Yawancin robobi suna da ƙarancin juriya na zafi, babban haɓakar haɓakar thermal da sauƙin ƙonewa;
7. Rashin kwanciyar hankali na girma da sauƙi don lalata;
8. Yawancin robobi suna da ƙarancin zafin jiki mara kyau, sun zama gaggautsa a ƙananan zafin jiki da sauƙin shekaru;
9. Wasu robobi suna da sauƙin narkewa a cikin kaushi.
10. Ana iya raba robobi gida biyu: thermosetting da thermoplastic.Ba za a iya sake fasalin tsohon don amfani ba, kuma ana iya sake yin na ƙarshe.Thermoplasticity yana da babban elongation na jiki, gabaɗaya 50% zuwa 500%.Ƙarfin ba ya bambanta gaba ɗaya a layi a cikin elongations daban-daban.
Akwai asali nau'ikan nau'ikan nau'ikan kwayoyin halitta na robobi: na farko tsarin layi ne, kuma mahallin polymer mai wannan tsarin ana kiran shi layin polymer fili;na biyu tsarin jiki ne, kuma sinadarin polymer mai wannan tsarin shi ake kira fili.Yana da babban fili polymer.Wasu polymers suna da sarƙoƙi masu reshe, waɗanda ake kira polymers masu rassa, waɗanda ke cikin tsarin layi.Ko da yake wasu polymers suna da haɗin kai tsakanin kwayoyin halitta, amma ƙananan hanyoyin haɗin kai, wanda ake kira tsarin cibiyar sadarwa, na cikin tsarin jiki.
Tsari daban-daban guda biyu, suna nuna kaddarorin gaba biyu.Tsarin layi na layi, dumama na iya narke, ƙarancin taurin da gaggawa.Tsarin jiki yana da taurin mafi girma da ɓarna.Filastik suna da sifofi biyu na polymers, thermoplastics da aka yi da polymers masu linzami, da kuma robobin thermoset ɗin da aka yi da manyan polymers.
