Kodi Polymerization ndi chiyani?

Polymerization ndi machitidwe omwe ma monomers (mamolekyu ang'onoang'ono) amaphatikizidwa kuti apange polima (molekyulu yayikulu). Izi zimaphatikizapo kupanga ma covalent bond pakati pa ma monomers, zomwe zimapangitsa kuti pakhale unyolo wofanana ndi mayunitsi obwereza.

Polymerization imatha kuchitika m'njira zosiyanasiyana, kuphatikiza polymerization ndi condensation polymerization. Kuphatikiza apo ma polymerization, ma monomers amalumikizidwa palimodzi kudzera muzochita zingapo zama mankhwala zomwe zimawonjezera monoma imodzi panthawi imodzi ku unyolo wa polima womwe ukukula. Izi nthawi zambiri zimafuna kugwiritsa ntchito chothandizira kuyambitsa zomwe zikuchitika. Zitsanzo zowonjezera ma polima ndi polyethylene, polypropylene, ndi polystyrene.

Komano, condensation polymerization, imaphatikizapo kuchotsa kamolekyu kakang'ono, monga madzi kapena mowa, monga ma monomers amaphatikizana kupanga polima. Izi zimafuna mitundu iwiri yosiyana ya ma monomers, iliyonse ili ndi gulu lokhazikika lomwe lingathe kupanga mgwirizano wogwirizana ndi mzake. Zitsanzo za ma polima a condensation ndi nayiloni, poliyesitala, ndi polyurethane.

Polymerization imagwiritsidwa ntchito pazinthu zosiyanasiyana, kuphatikiza kupanga mapulasitiki, ulusi, zomatira, zokutira, ndi zida zina. The zimatha chifukwa polima akhoza ogwirizana ndi kusintha mtundu ndi kuchuluka kwa monomers ntchito, komanso zikhalidwe za polymerization anachita.
