Nucleating agent ni ubwoko bwimikorere mishya ishobora kunoza imiterere yumubiri nubukanishi bwibicuruzwa nko gukorera mu mucyo, kurabagirana hejuru, imbaraga zingana, gukomera, ubushyuhe bwo kugoreka ubushyuhe, kurwanya ingaruka, kurwanya ibimera, nibindi muguhindura imyitwarire ya kristu ya resin. . Ikoreshwa cyane mubikorwa byo gukora plastiki zuzuye za kirisiti nka polyethylene na polypropilene mumodoka, ibikoresho byo murugo, ibiryo, ibikoresho bya elegitoroniki, hamwe nubuvuzi. Kurugero, nucleating agent nikintu cyingenzi mugukora ibisigisigi bikora cyane nka eregitoronike yo hejuru ya polypropilene, hejuru cyane-gukomera, gukomera-gukomeye, hamwe na polipropilene-hrstalline, β-kristaline polypropilene, hamwe nibikoresho bya polipropilene byahinduwe kubinyabiziga Gitoya. Mugushyiramo ibintu byihariye bya nucleating, resin hamwe no kurushaho gukorera mu mucyo, gukomera, no gukomera birashobora kubyara. Hamwe n'ubwiyongere bugaragara mu musaruro w’imbere mu gihugu wa polipropilene ikora cyane isaba kongerwamo ingufu za nucleating hamwe nubwiyongere bwihuse bwibikenerwa byorohereza amamodoka hamwe na bateri ya lithium itandukanya, hari iterambere ryinshi ryisoko ryabakozi ba nucleating.
Hariho ubwoko bwinshi bwaingirabuzimafatizo, n'ibicuruzwa byabo bikomeje gutera imbere. Ukurikije uburyo butandukanye bwa kirisiti iterwa na nucleating agent, zirashobora kugabanywamo α-kristaline nucleating agent na β-crystalline nucleating agent. Kandi α-kristaline nucleating agent irashobora gushyirwa muburyo bwa organic organique, organic, na polymer ukurikije itandukaniro ryimiterere. Ibikoresho bya nucleaux organique birimo cyane cyane nucleaux yateje imbere nka talc, calcium oxyde, na mika, zidahenze kandi byoroshye kubona ariko zifite umucyo muke hamwe nuburabyo. Ibikoresho bya nucleating organique birimo cyane cyane imyunyu ngugu ya acide karubike, umunyu wa fosifate, umunyu wa sorbitol benzaldehyde, nibindi. Muri byo, ibikomoka kuri sorbitol benzaldehyde kuri ubu ni ibintu bya nucleaux bikuze cyane, bifite imikorere myiza nibiciro biri hasi, kandi byahindutse cyane mubikorwa, bitandukanye. , hamwe nubunini bunini bwubwoko bwa nucleating agent haba mugihugu ndetse no mumahanga. Ibikoresho bya polymer byerekana cyane cyane gushonga-ingingo ya polymeric nucleating agent, nka polyvinylcyclohexane na polyvinylpentane. β-kristaline nucleating agent igizwe ahanini nubwoko bubiri: umubare muto wibintu byinshi bya polycyclic hamwe na quasi-planar, hamwe nibigizwe na acide dicarboxylic acide na okiside, hydroxide, numunyu wibyuma biva mumatsinda ya IIA kumeza yibihe. β-kristaline nucleating agent itanga ubushyuhe bwubushyuhe bwibicuruzwa mugihe bitezimbere ingaruka zabyo.
Ingero zimikorere yimikorere nibisabwa mubikorwa bya Nucleating
| Ibicuruzwa | Imikorere Ibisobanuro | Porogaramu |
| Umukozi wa Nucleating agent | Irashobora kunoza cyane gukorera mu mucyo ya resin, kugabanya igihu hejuru ya 60%, mugihe wongeyeho ubushyuhe bwo kugoreka ubushyuhe hamwe nubushyuhe bwa kristu ya resin na 5 ~ 10 ℃, no kuzamura modulus ya flexural kuri 10% ~ 15%. Iragabanya kandi kuzenguruka, izamura umusaruro, kandi ikomeza ibicuruzwa bihamye. | Indanganturo yo hejuru ya Polypropilene (cyangwa MI MI Polypropilene) |
| Rigidifying Agent Nucleating Agent | Irashobora kunoza cyane imiterere yubukanishi bwa resin, hamwe no kwiyongera kwa flexural modulus no kugonda imbaraga zirenga 20%, kimwe no kwiyongera k'ubushyuhe bwo kugoreka ubushyuhe kuri 15 ~ 25 ℃. Hariho kandi iterambere ryuzuye kandi ryuzuye mubice bitandukanye nkubushyuhe bwa kristu hamwe nimbaraga zingaruka, bivamo kugabanuka kuringaniza no kugabanya impinduka zintambara yibicuruzwa. | Indanganturo ya Melt Yerekana Polypropilene, Nshya-Rigidite, Gukomera-Gukomeye, hamwe na-Crystallisation Polypropilene, Ibikoresho byahinduwe bya Polypropilene kubikoresho bya Automotive Thin-Wall Porogaramu |
| β-Crystalline Gukomera Nucleating Agent | Irashobora gukora neza gushiraho β-kristalline polypropilene, hamwe na β-kristalline igipimo cyo hejuru ya 80%, kuzamura cyane imbaraga zingaruka za polypropilene resin, kandi kuzamura bishobora kugera inshuro zirenga 3. | Indanganturo yo hejuru ya Polypropilene, Nshya-Rigidite, Gukomera-hejuru, hamwe na Crystallisation Polypropilene, β-Crystalline Polypropylene |
