Muri plastiki, inyongeramusaruro zigira uruhare runini mukuzamura no guhindura imiterere yibikoresho. Nucleating agent no gusobanura ibintu ni bibiri byongeweho bifite intego zitandukanye mugushikira ibisubizo byihariye. Mugihe byombi bifasha kunoza imikorere yibicuruzwa bya pulasitiki, ni ngombwa kumva itandukaniro riri hagati yibi bikoresho byombi nuburyo bigira uruhare mubicuruzwa byanyuma.
Guhera kuriingirabuzimafatizo, izi nyongeramusaruro zikoreshwa mukwihutisha inzira ya kristu ya plastike. Crystallisation ibaho mugihe iminyururu ya polymer itunganijwe muburyo butunganijwe, bikavamo imiterere ikomeye. Uruhare rwibikorwa bya nucleating nugutanga ubuso bwurunigi rwa polymer kugirango rwubahirize, rutezimbere imiterere ya kristu no kongera muri rusange ibintu bifatika. Mu kwihutisha kristu, ibikoresho bya nucleating byongera imiterere nubushyuhe bwa plastike, bigatuma bikomera kandi birwanya ubushyuhe.
Imwe mu mikorere ikoreshwa cyane ni talc, imyunyu ngugu izwiho ubushobozi bwo gutera kristu. Talc ikora nka nucleating agent, itanga urubuga rwa nucleation kumurongo wa polymer kugirango utegure hafi. Kwiyongera kwayo bivamo kwiyongera kwa kristallisation hamwe nuburyo bwiza bwa kirisiti, bigatuma ibikoresho bikomera kandi bigahinduka neza. Bitewe nibikenewe byihariye nibiranga ibicuruzwa bya pulasitike, ibindi bintu bitera imbaraga nka sodium benzoate, aside benzoic hamwe nu munyu wibyuma nabyo birashobora gukoreshwa.
Ku rundi ruhande, ibisobanuro ni inyongera zongera ubwiza bwa plastike mu kugabanya igihu. Igicu ni ugukwirakwiza urumuri mubintu, bikavamo igicu cyangwa cyoroshye. Uruhare rwo gusobanura abakozi nuguhindura materix ya polymer, kugabanya inenge no kugabanya ingaruka zo gukwirakwiza urumuri. Ibi bisubizo mubikoresho bisobanutse, bisobanutse neza, nibyiza cyane mubisabwa nko gupakira, lensike optique no kwerekana.
Kimwe mu bintu bisanzwe bikoreshwa mu gusobanura ni sorbitol, inzoga yisukari nayo ikora nka nucleating agent. Nkumukozi usobanura, sorbitol ifasha gukora kristu ntoya, isobanuwe neza muri matrise ya plastike. Izi kristu zigabanya gukwirakwiza urumuri, bigabanya cyane igihu. Sorbitol ikoreshwa kenshi hamwe nibindi bisobanuro nka benzoin n'ibikomoka kuri triazine kugirango bigerweho neza kandi bisobanutse kubicuruzwa byanyuma.
Mugihe ibintu byombi bisobanura kandi bisobanutse bifite intego imwe yo kuzamura imiterere ya plastiki, hagomba kumenyekana ko uburyo bwabo bwibikorwa butandukanye.Ibikoresho bya kirimbuzikwihutisha uburyo bwo korohereza ibintu, bityo bitezimbere imashini nubushyuhe, mugihe ibintu bisobanutse bihindura polymer matrix kugirango bigabanye urumuri kandi byongere neza neza.
Mu gusoza, nucleating agent hamwe nibisobanuro byingirakamaro nibyingenzi byingenzi mubijyanye na plastiki, kandi buri nyongeramusaruro ifite intego yihariye. Ibikoresho bya nucleaire byongera uburyo bwo gutegera, bityo bikazamura imiterere yubushyuhe nubushyuhe, mugihe ibintu bisobanutse bigabanya igihu kandi bikongera neza. Mugusobanukirwa itandukaniro riri hagati yibi bikoresho byombi, ababikora barashobora guhitamo inyongeramusaruro iboneye kugirango bagere ku gisubizo cyifuzwa kubicuruzwa byabo bya pulasitiki, byaba byongerewe imbaraga, birwanya ubushyuhe cyangwa neza neza.
