Masu kera jirgi na SMC suna magana game da halayen kayan kwalliya

①Yawancin robobi suna da haske a cikin nauyi, sinadarai barga, kuma ba za su yi tsatsa;

② Kyakkyawan juriya mai tasiri;

③Yana da kyau nuna gaskiya da juriya;

④ Kyakkyawan rufi da ƙananan ƙarancin thermal;

⑤ Janar tsari, mai kyau launi, ƙananan farashin aiki;

⑥Mafi yawan robobi suna da mummunan juriya na zafi, babban haɓakar haɓakar thermal da sauƙin ƙonewa;

⑦ Rashin kwanciyar hankali na ƙima da sauƙi na lalacewa;

⑧Mafi yawan robobi suna da ƙarancin ƙarancin zafin jiki kuma sun zama gaggautsa a ƙananan zafin jiki;

⑨ Sauƙin tsufa;

⑩ Wasu robobi suna iya narkewa cikin sauƙi a cikin kaushi.

Filastik za a iya raba kashi biyu: thermosetting da thermoplastic. Ba za a iya sake fasalin na farko da amfani da shi ba, kuma ana iya samar da na ƙarshe akai-akai. Akwai nau’ikan nau’ikan nau’ikan nau’ikan nau’ikan nau’ikan nau’ikan polymers na filastik:

Na farko shi ne tsarin layi na layi, kuma mahaɗin polymer mai wannan tsarin ana kiransa fili mai linzamin kwamfuta;

Na biyu shi ne tsarin nau’in jiki, kuma sinadarin polymer mai wannan tsarin shi ake kira da body type polymer compound.

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, ba su da haɗin kai, wanda ake kira tsarin cibiyar sadarwa kuma yana cikin tsarin jiki. Tsari daban-daban guda biyu, suna nuna kaddarorin gaba biyu. Tsarin layi na layi (ciki har da tsarin reshe) polymers suna da halaye na elasticity da filastik saboda kasancewar kwayoyin halitta masu zaman kansu, wanda za’a iya narkar da su a cikin kaushi, ana iya narke ta hanyar dumama, kuma suna da ƙananan tauri da raguwa. Tun da babu macromolecules masu zaman kansu, polymer mai siffar jiki ba shi da elasticity da filastik, ba zai iya narke da narke ba, amma yana iya kumbura kawai, kuma yana da babban taurin da gaggawa. 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.
