O le a le Nucleating agent?

Nucleating agent o se ituaiga o faʻaopoopoga galuega fou lea e mafai ona faʻaleleia atili ai le tino ma le masini o oloa e pei o le manino, susulu i luga, malosi faʻamalosi, faʻamalosi, vevela vevela vevela, aʻafiaga aʻafiaga, fetolofi tetee, ma isi e ala i le suia o le amio tioata o resins. . E faʻaaogaina lautele i le gaosiga o le gaosiga o palasitika tioata e le atoatoa e pei o le polyethylene ma le polypropylene i totonu o le taʻavale, meafale, meaʻai, mea tau eletise, ma falemaʻi. Mo se faʻataʻitaʻiga, o le nucleating agent o se mea autu i le gaosiga o resini maualuga e pei o le maualuga o le faʻamaufaʻailoga polypropylene, fou maualuga-malosi, maualuga-maaa, ma le maualuga-crystallinity polypropylene, β-crystalline polypropylene, ma suiga polypropylene mea mo taavale. talosaga manifinifi puipui. E ala i le faʻaopoopoina o mea faʻapitoa faʻamaʻi, resins ma faʻaleleia atili le manino, faʻamalosi, ma le malosi e mafai ona gaosia. Faʻatasi ai ma le faʻatupulaia tele o le gaosiga i totonu o le atunuʻu o le polypropylene maualuga e manaʻomia ai le faʻaopoopoga o vailaʻau faʻamaʻi ma le televave o le faʻatupulaia o le manaʻoga mo le faʻamalama o taavale afi ma le lithium separators, o loʻo i ai le tele o atinaʻe gafatia mo le maketi o le nucleating agent.

E tele ituaiga ovaila'au fa'atosina, ma o loʻo faʻaauau pea ona faʻaleleia atili a latou oloa. E tusa ai ma ituaiga tioata eseese e faʻaosoina e le faʻamaʻi faʻamaʻi, e mafai ona vaevaeina i α-crystalline nucleating agents ma β-crystalline nucleating agents. Ma o α-crystalline nucleating agents e mafai ona fa'avasegaina atili i ituaiga inorganic, organic, ma polymer e fa'avae i luga o latou eseesega fa'avae. O vaila'au fa'ato'aga fa'aletino e masani lava ona aofia ai vaila'au fa'atosina ua vave fa'atupuina e pei o le talc, calcium oxide, ma le mika, e taugofie ma faigofie ona maua ae e le lelei le manino ma le iila. Organic nucleating agents e masani lava ona aofia ai carboxylic acid metal salts, phosphate metal salts, sorbitol benzaldehyde derivatives, ma isi. , ma le tele-volo ituaiga o vaila'au fa'atosina i totonu o le atunu'u ma fa'avaomalo. Polymer nucleating agents e masani lava o vaila'au fa'atosina polymeric maualuga, pei ole polyvinylcyclohexane ma polyvinylpentane. β-crystalline nucleating agents e masani lava ona aofia ai ni ituaiga se lua: o se numera itiiti o polycyclic compounds ma fausaga quasi-planar, ma i latou e aofia ai nisi o acids dicarboxylic ma oxides, hydroxides, ma masima o metals mai le Vaega IIA o le laulau faavaitaimi. β-crystalline nucleating agents faʻamautinoaina le vevela vevela o oloa aʻo faʻaleleia a latou aʻafiaga.
