Nucleating agentinokodzera mapurasitiki asina kukwana ecrystalline akadai se polyethylene uye polypropylene.Nekuchinja maitiro ekristallisation yeresin, inogona kukurumidza chiyero chekristallisation, kuwedzera crystallization density uye kukurudzira miniaturization yehukuru hwezviyo, kuitira kupfupisa kutenderera kutenderera, kunatsiridza kujeka uye pamusoro pechigadzirwa.Iyo nyowani inoshanda yekuwedzera yemuviri uye mekiniki zvivakwa senge gloss, kusimba kusimba, kusimba, kupisa kwekukanganisa tembiricha, kupikisa kuramba, uye kukambaira kuramba.

Nucleating agentinoreva kune inoshanda kemikari yekuwedzera iyo inogona kushandura chikamu chekristaro maitiro, kunatsiridza kujeka, kusimba, kupenya kwepamusoro, kusimba kwesimba uye tembiricha yekupisa yechigadzirwa, kupfupisa kutenderera kwechigadzirwa, uye kugadzirisa mashandiro uye mashandisiro ekushandisa kwechigadzirwa. chigadzirwa.

Thenucleating agentinoshandiswa semubatsiri wekugadzirisa wepolymer, uye maitiro ayo echiito anonyanya: munzvimbo yakanyungudutswa, sezvo nucleating agent inopa inodiwa crystal nucleus, iyo polima inoshanduka kubva kune yekutanga homogeneous nucleation kuenda kune heterogeneous nucleation, Nokudaro, iyo crystallization. kumhanya kunokwidziridzwa, chimiro chezviyo chinonatswa, uye zvinobatsira kuvandudza kuomarara kwechigadzirwa, kupfupisa kutenderera kutenderera, kuchengetedza kugadzikana kwechigadzirwa chekupedzisira, kurambidza kupararira kwechiedza, kuvandudza kujeka uye kupenya kwepasi uye kwemuviri uye. mechanical properties yepolymer.(zvakadai sekuoma, modulus), kupfupisa kutenderera kwekugadzirisa, nezvimwewo Sekirasi yakakosha ye nucleating agents, basa guru rejeri rakajeka nderokuvandudza optical effect yepolymer.Tsvagiridzo nekuvandudzwa kwemaajenti ekuti nucleating munyika yangu yakatanga muma1980s, uye kune marudzi mazhinji.Iye zvino anoshanda, akachipa uye ekutengesa nucleating agents anogona kunyanya kukamurwa kuita inorganic nucleating agents, organic nucleating agents uye polymer nucleating agents..Mukuwedzera, iyo shanduko yekushandura iyo inoshandura iyo α-crystal fomu muPP kune iyo β-crystal fomu inowanzoiswawo seye nucleating agent.
