Iyo yakajairwa yakajeka nucleating agents inogona kukamurwa kuita mhando mbiri: organic komisheni uye inorganic komisheni.
Inorganic Nucleating Agentsmaokisisa esimbi, akadai setalc, silica, titanium dioxide, benzoic acid zvichingodaro.Iyi mhando ye nucleating agent inoda saizi isingasviki 40m uye ndiyo yekutanga mhando ye nucleating agent inoshandiswa.Nekuti ivo havanyungudika mupolymer inonyungudika, ivo vanongogadzira makristasi embryos panguva yekunyunguduka recrystallization.Nekudaro, nekuda kweruvara rwayo, hazvina kunaka kuvandudza kujeka uye kupenya kwepamusoro kwechigadzirwa chakapedzwa mushure mekushandisa.Kunyangwe vashoma vanogadzira vachiri kushandiswa, asi iri yakaderera-giredhi chigadzirwa, maitiro eiyo dosage inodzikira gore negore, uye ichabviswa pakupedzisira.
The mainOrganic Nucleating Agentsane fatty carboxylic acid, anonhuwirira sipo yesimbi, organophosphate uye sorbitol benzylidene derivatives.Sorbitol uye organophosphate ndiyo inonyanya kushandiswa nucleating agents mumusika.
Ose ari maviri ane zviri nani transparent modification effect, asi imwe neimwe ine zvayakanakira nezvayakaipira
Sorbitol Nucleating Agentinogona kunyungudutswa mune yakanyungudutswaPP, wobva wagadzira homogeneous system, saka iyo nucleation mhedzisiro yakanaka, uye fusion nePPzvakanaka.Kujeka kuri nani pane organophosphates.Izvo zvakashata ndezvekuti flavour yemubereki aldehyde iri nyore kuburitswa panguva yekugadziriswa.
Organophosphate Nucleating Agentine zvimiro zvekudzivirira kwakanaka kwekupisa, kunhuhwirira.Asi iyo nucleating mhedzisiro uye pachena ishoma paneSorbitol Nucleating Agent, asi nemutengo wepamusoro uye kupararira kwakashata mukatiPP.
Iyo nucleating mechanism yemhando dzakasiyana dzenyucleating agents dzataurwa pamusoro apa dzinoenderana.Nekudaro, nekuda kwekumwe mutsauko wezvivakwa zve nucleating agents, kune zvakare misiyano yekuvandudza zvinhu zvePPmukugadzirisa.Semuenzaniso, sorbitol nucleating agent haingogone chete kuvandudza zvakanyanya kujeka uye kupenya kwepasi kwe.PP, asi zvakare kuvandudza zvimwe zvemuviri uye zvemagetsi zvimiro zvePP: kuvandudza kuomarara, tembiricha yekupisa deformation uye dimensional kugadzikana kwePP.Naizvozvo, dibenzylidene sorbitol ndiyo inonyanya kufarirwaTransparent Nucleating Agentmumusika.
