Nucleating agent imhando yezvitsva zvinoshanda zvekuwedzera izvo zvinogona kuvandudza hunhu uye mechaniki zvivakwa zvezvigadzirwa zvakaita sekujeka, kupenya kwepasi, kusimba kwesimba, kusimba, kupisa kwekupisa tembiricha, kupikisa kupikisa, kukambaira, nezvimwe nekushandura maitiro ekristalllization yeresin. . Inoshandiswa zvakanyanya mukugadzira mapurasitiki asina kukwana senge polyethylene uye polypropylene mumotokari, mudziyo wepamba, chikafu, zvemagetsi, uye minda yekurapa. Semuenzaniso, nucleating agent chinhu chakakosha mukugadzirwa kwepamusoro-performance resin senge yakakwira melt index polypropylene, nyowani yakakwirira-yakaomarara, yakakwirira-yakaoma, uye yakakwirira-crystallinity polypropylene, β-crystalline polypropylene, uye yakagadziridzwa polypropylene zvinhu zvemotokari. matete-madziro maapplication. Nekuwedzera chaiwo nucleating agents, marezeni ane kujeka kwakavandudzwa, kusimba, uye kuoma anogona kugadzirwa. Nekuwedzera kwakakosha mukugadzirwa kwemumba kweyepamusoro-inoita polypropylene iyo inoda kuwedzerwa kweiyo nucleating agents uye kukurumidza kukura kwekuda kwemotokari lightweighting uye lithium bhatiri separators, kune yakakura budiriro mukana weiyo nucleating agent musika mukati.

Kune marudzi akawanda enucleating agents, uye maitiro avo echigadzirwa anoramba achivandudza. Zvinoenderana neakasiyana mafomu ekristaro anokonzerwa neiyo nucleating agents, anogona kukamurwa kuita α-crystalline nucleating agents uye β-crystalline nucleating agents. Uye α-crystalline nucleating agents inogona kuverengerwa kuita inorganic, organic, uye polymer mhando zvichienderana nekusiyana kwavo kwemaitiro. Inorganic nucleating agents anonyanya kusanganisa ekutanga kugadzirwa nucleating agents senge talc, calcium oxide, uye mica, ayo asingadhure uye ari nyore kuwana asi asina kujeka uye kupenya kwepasi. Organic nucleating agents anonyanya kusanganisira carboxylic acid metal salts, phosphate metal salts, sorbitol benzaldehyde derivatives, etc. Pakati pavo, sorbitol benzaldehyde derivatives pari zvino ndiyo yakanyanyokura nucleating agents, nekushanda kwakanakisisa uye mitengo yakaderera, uye yakave inonyanya kugadzirwa, yakasiyana-siyana. , uye yakakura-vhoriyamu mhando ye nucleating agents mukati uye kunze kwenyika. Polymer nucleating agents anonyanya kunyungudika-polymeric nucleating agents, akadai sepolyvinylcyclohexane uye polyvinylpentane. β-crystalline nucleating agents inonyanya kuumbwa nemhando mbiri: nhamba shoma yepolycyclic compounds ine quasi-planar structures, uye iyo inoumbwa nemamwe dicarboxylic acids uye oxides, hydroxides, nemunyu wesimbi kubva muBoka IIA reperiodic table. β-crystalline nucleating agents inovimbisa tembiricha yekupisa yezvigadzirwa uku ichivandudza kupikisa kwavo.
