Ikoreshwa mu gukurura ibintu mu buryo bwa nucleating ni ubwoko bw'inyongeramusaruro nshya ishobora kunoza imiterere y'ibicuruzwa nko kugaragara neza, kugaragara neza kw'ubuso, imbaraga zo gukurura, gukomera, ubushyuhe bwo guhindagurika k'ubushyuhe, kudakora neza kw'ingaruka, kudakora neza kw'ibintu mu buryo bwa crystallization, nibindi binyuze mu guhindura imyitwarire ya resins. Ikoreshwa cyane mu gukora pulasitiki zidakora neza nka polyethylene na polypropylene mu modoka, ibikoresho byo mu rugo, ibiribwa, ibikoresho by'ikoranabuhanga, n'ubuvuzi. Urugero, ikoreshwa mu gukurura ibintu mu buryo bwa nucleating ni ingenzi mu gukora resins zikora neza nka polypropylene ifite imiterere myinshi, polypropylene nshya ifite imiterere ikomeye, gukomera cyane, n'ifite kristali nyinshi, polypropylene ya β-crystalline, n'ibikoresho bya polypropylene byahinduwe mu bikoresho by'imodoka bifite inkuta nto. Iyo hongewemo ikoreshwa ry'i ... Bitewe n’ubwiyongere bugaragara bw’umusaruro wa polypropylene ikora neza mu gihugu, bisaba ko hongerwamo ibikoresho bikoresha ikoranabuhanga rya nucleating agents ndetse n’ubwiyongere bwihuse bw’abakenera ibikoresho byo gupima amashanyarazi mu modoka na bateri za lithium, hari amahirwe menshi y’iterambere ku isoko ry’ibikoresho bikoresha ikoranabuhanga rya nucleating agents muri iki gihe.
Hariho ubwoko bwinshi bwaibikoresho bya nucleating, kandi imikorere y'ibicuruzwa byabyo ikomeje gutera imbere. Dukurikije imiterere itandukanye ya kristu iterwa n'ibintu bitera nucleus, bishobora kugabanywamo ibintu bitera nucleus bya α-crystalline na β-crystalline. Kandi ibintu bitera nucleus bya α-crystalline bishobora gushyirwa mu byiciro bito, organic, na polymer hashingiwe ku itandukaniro ry'imiterere yabyo. Ibintu bitera nucleus bya α-crystalline ahanini birimo ibintu bitera nucleus byakozwe hakiri kare nka talc, calcium oxide, na mica, bihendutse kandi byoroshye kubibona ariko bifite ubwiza buke n'ubuso budasobanutse neza. Ibintu bitera nucleus bya organic ahanini birimo umunyu wa aside carboxylic metal, umunyu wa fosfeti metal, sorbitol benzaldehyde derivatives, nibindi. Muri byo, ibintu bitera nucleus bya sorbitol benzaldehyde ni byo bitera nucleus byakuze cyane, bifite imikorere myiza kandi bihendutse, kandi byabaye ubwoko bw'ibintu bitera nucleus byateye imbere cyane, bitandukanye, kandi bifite ingano nini haba mu gihugu no mu mahanga. Ibintu bitera nucleus bya polymer ahanini ni ibintu bitera nucleus bya polymeric bifite aho bihuriye no gushonga cyane, nka polyvinylcyclohexane na polyvinylpentane. Ibintu bitera imiterere ya β-crystalline ahanini bigizwe n'ubwoko bubiri: umubare muto w'ibintu bitera imiterere ya polycyclic bifite imiterere ya quasi-planar, n'ibigizwe na aside dicarboxylic na oxydes zimwe na zimwe, hydroxides, n'umunyu w'ibyuma biva mu itsinda rya IIA ry'imbonerahamwe y'igihe. Ibintu bitera imiterere ya β-crystalline byemeza ubushyuhe bw'ubushyuhe bw'ibicuruzwa mu gihe byongera ubushobozi bwo kubirwanya.
Ingero z'Imikorere y'Ibicuruzwa n'Imikoreshereze y'Ibintu Bikora ku Mikorobe
| Ibicuruzwa | Ibisobanuro by'Imikorere | Porogaramu |
| Umukozi Ukoresha Nucleating Unyuze mu Buryo Bugaragara | Bishobora kunoza cyane ubwisanzure bya resin, bigabanya ubushyuhe ku kigero kirenga 60%, mu gihe cyongera ubushyuhe bwo guhindura ubushyuhe n'ubushyuhe bwo gushushanya ya resin ku bushyuhe bwa 5 ~ 10℃, no kunoza uburyo bwo gukurura imitsi ku kigero cya 10% ~ 15%. Binagabanya igihe cyo gucura, byongera umusaruro, kandi bigakomeza guhagarara neza mu rugero rw'ibicuruzwa. | Polypropylene ifite igipimo cyo kugabanuka cyane (cyangwa Polypropylene ya High MI) |
| Umukozi Urinda Ingufu za Nucleating | Bishobora kunoza cyane imiterere ya resin, hamwe n'ubwiyongere bw'uburyo bwo guhindagurika kw'imitsi n'imbaraga zo kuzunguruka birenga 20%, ndetse no kwiyongera k'ubushyuhe bwo guhindura ubushyuhe ho dogere 15 ~ 25°C. Hariho kandi iterambere rirambuye kandi riringaniye mu bintu bitandukanye nko gushyuha kw'amakristale n'imbaraga z'ingaruka, bigatuma habaho kugabanuka kuringaniye no kugabanya kwangirika kw'ibicuruzwa. | Polypropylene yo mu bwoko bwa High Melt Index, Polypropylene nshya ifite ubukana bwinshi, ikomeye cyane, kandi ifite ubukana bwinshi, ibikoresho bya polypropylene byahinduwe mu bijyanye no gukoresha mu modoka. |
| Umuti wo gukamura ibyuma bya β-Crystalline Toughening Nucleating | Ishobora gutuma habaho neza polypropylene ya β-crystalline, hamwe n'igipimo cyo guhindura β-crystalline kirenga 80%, kunoza cyane imbaraga z'ingaruka za polypropylene resin, kandi iterambere rishobora kugera ku nshuro zirenga 3. | Polypropylene yo mu bwoko bwa High Melt Index, Polypropylene nshya yo mu bwoko bwa High-Rigidity, High-Toughness, na High-Crystallization Polypropylene, β-Crystalline Polypropylene |
