Waa maxay Polymerization?

Polymerization waa falcelin kiimikaad kaas oo monomers (molecules yaryar) la isku daray si ay u sameeyaan polymer (molecule weyn). Habkani waxa ku lug leh samaynta curaarta covalent ee u dhexeeya monomers, taasoo keentay qaab-dhismeedka silsilad u eg oo leh unug soo noqnoqda.

Polymerization waxay ku dhici kartaa habab kala duwan, oo ay ku jiraan polymerization-ka dheeraadka ah iyo polymerization uumiga. polymerization ka sokow, monomers-yada ayaa la isku daraa iyada oo loo marayo falcelin kiimiko oo taxane ah oo ku daraya hal monomer markiiba silsiladda polymer ee sii kordheysa. Habkani wuxuu caadi ahaan u baahan yahay isticmaalka kicinta si loo bilaabo falcelinta. Tusaalooyinka polymers-ka dheeriga ah waxaa ka mid ah polyetylen, polypropylene, iyo polystyrene.

polymerization Uumiga, dhanka kale, waxay ku lug leedahay baabi'inta molecule yar, sida biyaha ama aalkolada, maadaama monomers ay isku daraan si ay u sameeyaan polymer-ka. Habkani wuxuu caadi ahaan u baahan yahay laba nooc oo kala duwan oo monomers ah, mid walbana leh koox falcelin ah oo ka samaysan kara dammaanad wadajir ah kan kale. Tusaalooyinka polymers-ka uumiga waxaa ka mid ah naylon, polyester, iyo polyurethane.

Polymerization waxaa loo isticmaalaa codsiyo kala duwan oo kala duwan, oo ay ku jiraan wax soo saarka caagadaha, fiilooyinka, xabagta, dahaarka, iyo walxo kale. Sifooyinka polymer-ka soo baxay waxaa lagu habeyn karaa iyadoo la hagaajinayo nooca iyo tirada monomers ee la isticmaalo, iyo sidoo kale shuruudaha falcelinta polymerization.
