CaagadahaWaxay ka samaysan yihiin polymers, laakiin qaar ka mid ah polymers sida bioopolymers ma aha balaastiig.Walxaha caaga ah waxaa loo isticmaalaa nolol maalmeedka sida kombayutarada, qalinka, teleefoonada gacanta, saxanadaha is haysta, pendrive, iyo burushka cadayga iwmHalabuurka kiimikada ee balaastikada waxaa ka mid ah silsiladaha kaarboon, ogsijiin, baaruud ama nitrogen.
Taariikhda balaastikada
Sanadkii 1823 kii, farmashiyaha Scotland Charles Macintosh wuxuu helay caag dabiici ah oo ka sameysan geesaha iyo tortoiseshell, 1820 kiiba caag ah 1820kii, farmashiyaha reer Scotland ee Charles Macintosh wuxuu helay caag. Sannadkii 1869kii, John W. Hyatt waxa uu ikhtiraacay Celluloid [wax olol ah oo aan midab lahayn] Sannadkii 1872kii, walaalihii Hyatt waxa ay daah-fureen mishiinka wax-qabashada caagga ah ee ugu horreeya ee la isku duro. 1880 Eastman Kodak mashiinka shatiyada ee soo saarista filim sawiro joogto ah oo ku salaysan cellulose nitrate.1900 caag timeline 1908, Jacques E. Brandenberger ikhtiraacay Cellophane [waxyaabaha cellulose hufan] Sannadkii 1909, Casein balaastikada, oo laga helay caano, oo uu sameeyay Erinoid, H. Baekeland 1909 Sannadkii 1916, Rolls Royce wuxuu bilaabay inuu isticmaalo phenol formaldehyde gudaha baabuurkiisa, sannadkii 1920kii, Polyvinyl chloride ama PVC ayaa la sameeyay 1925-kii, ereyga caaga ah ayaa la sameeyay. Sannadkii 1933-kii, Fawcett iyo Gibson waxay heleen maaddada polyetylen-ka ah sannadkii 1938-kii, waxaa la sameeyay cadayga ugu horreeya ee tufts naylon ah. 1949, DuPont waxa uu soo saaray wax soo saarka Lycra oo ku salaysan polyurethane, sannadkii 1953-kii, 1959-kii Barbie Doll ayaa lagu soo bandhigay American International. Sannadkii 1965-kii DuPont waxa ay sii daysay badeecooyin leh magaca ganacsiga ee Kevlar. Sannadkii 1973-kii, dhalooyinka cabitaanka ee Polyethylene terephthalate ayaa la soo bandhigay. 1988, calaamadaha dib-u-warshadaynta saddex-geesoodka ah ee la xidhiidha balaastikada ayaa la soo bandhigay. Nidaamka] waxaa la aasaasay 2005 sanadkan NASA waxay sahamisaa faa'iidooyinka polyetylenka ku salaysan RFX1 [RFX1 loo isticmaalo dhismaha hawada sare] 2011, vinylplus - barnaamijka sii wadista oo la aasaasayIn 2012 dharka PVC ee loo isticmaalo dhismaha goobaha Olombikada London2020 wax soo saarka PVC wuxuu gaari doonaa 800,000 tones sanadkii 2022 ee sanadkan garoonka bandhiga koobka aduunka ee FIFA ee Qatar ayaa qorsheynaya inuu isticmaalo maro PVC ah oo heer sare ah, oo saddex geesood ah si loo abuuro kaarboon eber ah.
Habka wax soo saarka ee balaastikada
