Ma nucleating othandizira owoneka bwino amatha kugawidwa m'mitundu iwiri: organic compounds ndi inorganic compounds.
Ma Inorganic Nucleating Agentsndi oxides makamaka zitsulo, monga talc, silika, titaniyamu woipa, asidi benzoic ndi zina zotero.Mtundu uwu wa nucleating wothandizira umafuna tinthu kukula kosakwana 40m ndipo ndi mtundu woyamba wa nucleating wothandizira.Chifukwa samasungunuka mu polima amasungunuka, mwachibadwa amapanga mazira a kristalo panthawi yosungunuka.Komabe, chifukwa cha mtundu wake, sikuli bwino kuwongolera kuwonekera ndi gloss pamwamba pa chinthu chomalizidwa mutagwiritsa ntchito.Ngakhale opanga ochepa akugwiritsabe ntchito, koma ndi mankhwala otsika kwambiri, machitidwe a mlingo wake amachepetsa chaka ndi chaka, ndipo adzathetsedwa potsirizira pake.
ChachikuluMa organic Nucleating Agentsndi mafuta a carboxylic acid, sopo wachitsulo wonunkhira, organophosphate ndi sorbitol benzylidene zotumphukira.Sorbitol ndi organophosphate ndizomwe zimagwiritsidwa ntchito kwambiri pamsika.
Onse a iwo ali bwino mandala kusinthidwa zotsatira, koma aliyense ali ubwino ndi kuipa
Sorbitol Nucleating Agentakhoza kusungunuka mu kusungunukaPP, ndiye kupanga homogeneous dongosolo, kotero nucleation zotsatira zabwino, ndi maphatikizidwe ndiPPndi zabwino.Kuwonekera ndikwabwino kuposa organophosphates.Choyipa ndichakuti kukoma kwa aldehyde ya makolo ndikosavuta kumasulidwa panthawi yokonza.
Organophosphate Nucleating Agentali ndi mawonekedwe abwino kutentha kutentha, osanunkhiza.Koma zotsatira zake nucleating ndi poyera ndi zochepa kuposaSorbitol Nucleating Agent, koma ndi mtengo wokwera komanso kubalalitsidwa koyipa mkatiPP.
Njira yopangira nyukiliya ya mitundu yosiyanasiyana ya nucleating agents yomwe tatchula pamwambapa ndi yokhazikika.Komabe, chifukwa cha kusiyana kwa zinthu za nucleating agents, palinso kusiyana kwina pakuwongolera katundu waPPmu processing process.Mwachitsanzo, sorbitol nucleating agent sikuti imangowonjezera kuwonekera komanso gloss ya pamwamba.PP, komanso kusintha zina thupi ndi makina katundu waPP: kupititsa patsogolo kukhazikika, kutentha kwa kutentha ndi kukhazikika kwapakatiPP.Chifukwa chake, dibenzylidene sorbitol ndi yotchuka kwambiriTransparent Nucleating Agentkumsika.
