Yawancin lokaci muna koya game da robobi ta fuskar kamanni, launi, tashin hankali, girma, da sauransu, to yaya game da robobi ta mahanga ta sinadarai?
Resin roba shine babban bangaren filastik, kuma abun ciki a cikin filastik gabaɗaya shine 40% zuwa 100%.Saboda babban abun ciki da kaddarorin resins waɗanda sau da yawa ke ƙayyade kaddarorin robobi, mutane sukan ɗauki resins a matsayin mai kama da robobi.
Filastik wani fili ne na polymer wanda aka yi da monomer a matsayin ɗanyen abu kuma aka sanya shi ta hanyar ƙari ko ƙarawa.Juriyarsa ga nakasa yana da matsakaici, tsakanin fiber da roba.Ya ƙunshi additives kamar wakilai da pigments.
Ma'anar Filastik da Haɗawa: Filastik duk wani nau'in polymer na roba ne ko na roba.A takaice dai, filastik ko da yaushe yana ƙunshi carbon da hydrogen, kodayake wasu abubuwa na iya kasancewa.Duk da yake ana iya yin robobi daga kusan kowane nau'in polymer, yawancin robobin masana'antu ana yin su ne daga sinadarai na petrochemicals.Thermoplastics da thermoset polymers iri biyu ne na robobi.Sunan "roba" yana nufin filastik, ikon nakasa ba tare da karya ba.Polymers da ake amfani da su don yin robobi kusan koyaushe ana haɗe su da abubuwan ƙarawa, gami da masu canza launi, masu yin robobi, stabilizers, filler, da abubuwan ƙarfafawa.Wadannan additives suna shafar nau'in sinadarai, sinadarai da kayan aikin injiniya na robobi, da kuma farashi.
Thermosets da Thermoplastics: Thermoset polymers, wanda kuma aka sani da thermosets, suna warkewa zuwa siffar dindindin.Sun kasance amorphous kuma an yi imani da cewa suna da nauyin kwayoyin halitta mara iyaka.Thermoplastics, a daya bangaren, za a iya zafi da kuma sake fasalin akai-akai.Wasu thermoplastics amorphous ne, yayin da wasu suna da wani bangare na tsarin crystalline.Thermoplastics yawanci suna da ma'aunin kwayoyin tsakanin 20,000 da 500,000 AMU.
