Nucleating agent imhando yechinhu chitsva chinoshanda chinogona kuvandudza hunhu hwezvinhu zvakaita sekujeka, kupenya kwepadenga, simba rekukwesha, kuomarara, kupisa kupisa, kuramba kukanganiswa, kuramba kukwira, nezvimwewo nekuchinja maitiro ekugadzira ma crystallization ema resin. Inoshandiswa zvakanyanya mukugadzirwa kwemapurasitiki asina kuzara crystalline akadai se polyethylene ne polypropylene mumotokari, mumidziyo yemumba, muchikafu, mumagetsi, uye muminda yekurapa. Semuenzaniso, nucleating agent chinhu chakakosha mukugadzirwa kwema resin anoshanda zvakanyanya akadai se high melt index polypropylene, new high-rigidity, high-toughness, uye high-crystallinity polypropylene, β-crystalline polypropylene, uye modified polypropylene materials ekushandisa mota dzakatetepa. Nekuwedzera ma nucleating agents chaiwo, ma resin ane kujeka kwakawedzerwa, kuomarara, uye kuomarara anogona kugadzirwa. Nekuwedzera kukuru kwekugadzirwa kwepolypropylene yepamusoro-soro munyika kunoda kuwedzerwa kwezvinhu zvinoshandisa nucleating agents uye kukura nekukurumidza kwekudiwa kwezvishandiso zvemagetsi zvinoshandisa mota uye zvinoparadzanisa mabhatiri e lithium, kune mukana mukuru wekuvandudza musika wezvinhu zvinoshandisa nucleating agents mu.
Kune mhando dzakawanda dzezvinhu zvinogadzira nucleotides, uye mashandiro ezvigadzirwa zvavo anoramba achivandudzwa. Zvichienderana nemafomu akasiyana ekristaro anokonzerwa nemidziyo yekuuraya masero, inogona kukamurwa kuita α-crystalline nucleating agents uye β-crystalline nucleating agents. Uye α-crystalline nucleating agents dzinogona kupatsanurwa mumhando dze inorganic, organic, uye polymer zvichienderana nekusiyana kwechimiro chadzo. Inorganic nucleating agents inonyanya kusanganisira midziyo yekuuraya masero yakagadzirwa kare senge talc, calcium oxide, uye mica, iyo isingadhuri uye iri nyore kuwana asi isina kujeka uye surface gloss. Organic nucleating agents inonyanya kusanganisira carboxylic acid metal salts, phosphate metal salts, sorbitol benzaldehyde derivatives, nezvimwewo. Pakati padzo, sorbitol benzaldehyde derivatives pari zvino ndiyo midziyo yekuuraya masero yakakura, ine mashandiro akanaka uye mitengo yakaderera, uye yave mhando yemidziyo yekuuraya masero yakagadzirwa zvakanyanya, yakasiyana-siyana, uye yakakura kwazvo mukati menyika nepasi rese. Polymer nucleating agents inonyanya kuve polymeric nucleating agents ine polymeric nucleating agents, senge polyvinylcyclohexane nepolyvinylpentane. Zvinhu zvinoumba nucleating agents zve β-crystalline zvinonyanya kuve nemhando mbiri: nhamba diki yema polycyclic compounds ane quasi-planar structures, uye ayo anoumbwa nemamwe ma dicarboxylic acids nema oxides, hydroxides, uye munyu wesimbi kubva kuGroup IIA ye periodic table. Zvinhu zvinoumba nucleating agents zve β-crystalline zvinovimbisa tembiricha yekupisa kwezvigadzirwa uku zvichivandudza resistance yazvo.
Mienzaniso yeMabasa eChigadzirwa uye Mashandisirwo eNucleating Agents
| Zvigadzirwa | Tsananguro yeBasa | Mashandisirwo |
| Mumiriri weNucleating Akajeka | Zvinogona kuvandudza zvikuru kujeka kwechinhu ye resin, ichideredza mhute neinopfuura 60%, ukuwo zvichiwedzera tembiricha yekukanganisa kupisa uye tembiricha yekukwesha ye resin ne 5 ~ 10℃, uye kunatsiridza flexural modulus ne10% ~ 15%. Zvinopfupisawo kutenderera kwekuumba, inowedzera kushanda zvakanaka kwekugadzira, uye inochengetedza kugadzikana kwehukuru hwechigadzirwa. | Polypropylene Yakanyanya Kunyunguduka (kana High MI Polypropylene) |
| Mumiriri Anosimbisa Nucleating | Inogona kuvandudza zvakanyanya hunhu hwemuchina hwe resin, nekuwedzera kwe flexural modulus uye simba rekukotama rinodarika 20%, pamwe nekuwedzera kwekupisa kunochinja-chinja ne15~25℃. Kunewo kuvandudzwa kwakazara uye kwakaringana muzvinhu zvakasiyana-siyana zvakaita sekupisa kwekristaro uye simba rekurova, zvichikonzera kudzikira kwakaringana uye kudzikira kwekushanduka kwewarpage yechigadzirwa. | High Melt Index Polypropylene, Itsva High-Rigidity, High-Toughness, uye High-Crystallization Polypropylene, Yakagadziriswa Polypropylene Material yeMotokari Thin-Wall Applications |
| Mushonga wekusimbisa β-Crystalline Nucleating | Inogona zvinobudirira kukonzera kuumbwa kwe β-crystalline polypropylene, ine chiyero chekushandura cheβ-crystalline chinodarika 80%, kuwedzera zvakanyanya simba rekusimba kwe polypropylene resin, uye kuwedzerwa kunogona kusvika kanopfuura katatu. | High Melt Index Polypropylene, New High-Rigidity, High-Toughness, uye High-Crystallization Polypropylene, β-Crystalline Polypropylene |
