Isicelo

Ukususela oko kwaveliswa iiplastiki yi-American Baekeland kwiminyaka elikhulu eyadlulayo, iiplastiki zisasazeke ngokukhawuleza kwihlabathi liphela ngeenzuzo zazo ezinkulu, nto leyo eyenza kube lula kakhulu ubomi babantu. Namhlanje, iimveliso zeplastiki ziye zaba zizinto ezifunekayo kubomi bemihla ngemihla, kwaye ukusetyenziswa kweemveliso zeplastiki, ngakumbi iimveliso zeplastiki ezibonakalayo, kukhula ngokukhawuleza unyaka nonyaka.

I-transparent nucleating agent liqela elikhethekileyo le-nucleating agent, enepropathi yokuhlanganisa ye-self polymerization ye-physical ngokwayo, kwaye inokunyibilikiswa kwi-melt polypropylene ukuze yenze isisombululo esifanayo. Xa i-polymer ipholile, i-transparent agent iyakristala kwaye yenze inethiwekhi efana nefayibha, esasazwa ngokulinganayo kwaye ingaphantsi kobude bokukhanya okubonakalayo. Njenge-heterogeneous crystal core, i-nucleation density ye-polypropylene iyanda, kwaye i-spherulite efanayo necociweyo yenziwa, enciphisa ukurhawuzelelwa kunye nokusasazeka kokukhanya kwaye yonyusa ukucaca.

I-Uni-NUCA inenzuzo ephezulu yokuncipha kolusu. Kwixabiso elifanayo lolusu (ngokwemigangatho yeshishini), ubungakanani be-Uni-NUCA bungaphantsi kwe-20% kunezinye ii-nucleating agents! I-Anc idala imvakalelo yokubona ebhlowu.

Xa kuthelekiswa nezinye ii-nucleating agents, iipropati zoomatshini zeemveliso zePP ziphuculwe ngokucacileyo ngokongeza i-Uni-NUCA.

Xa kuthelekiswa nezinye iiarhente, i-Uni-NUCA ineenzuzo ezingabizi kakhulu:

Ukonga iindleko — ukusetyenziswa kwe-Uni-NUCA kuya konga i-20% yeendleko zezongezo ngesiphumo esifanayo sexabiso lomswakama.
Ukucubungula ubushushu obuphantsi — inqanaba le-meltinq le-Uni-NUCA lisondele kwi-PP kunye nokuxuba okulula kokunyibilika.
Ukonga amandla – gcina i-20% yamandla ngokongeza i-Uni-NUCA kwiimveliso ze-PP.
I-Beautiull–Uni-NUCA iphucula ukubonakala kweemveliso zePolypropylene kwaye idala izixhobo ezibonakalayo eziluhlaza okwesibhakabhaka.
