Menene Polymerization?

Polymerization wani sinadari ne wanda aka hada monomers (kananan kwayoyin halitta) don samar da polymer (babban kwayoyin halitta). Wannan tsari ya ƙunshi samuwar haɗin kai tsakanin monomers, yana haifar da tsari mai kama da sarka tare da maimaita raka'a.

Polymerization na iya faruwa ta hanyoyi daban-daban, ciki har da ƙari na polymerization da polymerization na tari. Bugu da kari polymerization, monomers suna haɗuwa tare ta hanyar jerin halayen sinadarai waɗanda ke ƙara monomer ɗaya a lokaci ɗaya zuwa sarkar polymer mai girma. Wannan tsari yawanci yana buƙatar amfani da mai kara kuzari don fara amsawa. Misalan ƙarin polymers sun haɗa da polyethylene, polypropylene, da polystyrene.

Polymerization na condensation, a gefe guda, ya ƙunshi kawar da ƙananan ƙwayoyin cuta, kamar ruwa ko barasa, kamar yadda monomers ke haɗuwa don samar da polymer. Wannan tsari yawanci yana buƙatar nau'ikan monomers iri biyu daban-daban, kowannensu yana da rukunin amsawa wanda zai iya samar da haɗin gwiwa tare da ɗayan. Misalai na polymers na narke sun haɗa da nailan, polyester, da polyurethane.

Ana amfani da polymerization a cikin aikace-aikace masu yawa, ciki har da samar da robobi, fibers, adhesives, coatings, da sauran kayan. Ana iya keɓance kaddarorin da aka haifar da polymer ta hanyar daidaita nau'in da adadin adadin monomers da aka yi amfani da su, da kuma yanayin halayen polymerization.
