Wakiilka Nucleating-ka waa nooc ka mid ah waxyaabaha cusub ee lagu daro ee shaqeynaya kaas oo hagaajin kara sifooyinka jireed iyo kuwa farsamada ee alaabada sida hufnaanta, dhalaalka dusha sare, xoogga jiidista, adkaanta, heerkulka qallooca kulaylka, iska caabbinta saameynta, iska caabbinta gurguurta, iwm. iyadoo la beddelayo dhaqanka kirismaska ee resins-ka. Waxaa si weyn loogu isticmaalaa habka wax soo saarka balaastikada kirismaska ee aan dhammaystirnayn sida polyethylene iyo polypropylene ee baabuurta, qalabka guriga, cuntada, elektarooniga, iyo goobaha caafimaadka. Tusaale ahaan, wakiilka nucleating-ka waa walax muhiim ah oo ku jirta soo saarista resins-ka waxqabadka sare leh sida polypropylene-ka dhalaalka sare leh, adkeysi sare oo cusub, adkeysi sare, iyo polypropylene-ka kirismaska sare leh, polypropylene-ka β-crystalline, iyo walxaha polypropylene ee wax laga beddelay ee loogu talagalay codsiyada khafiifka ah ee baabuurta. Iyadoo lagu darayo wakiillo nucleating gaar ah, resins-ka leh hufnaan la hagaajiyay, adkeysi, iyo adkeysi ayaa la soo saari karaa. Iyadoo kororka weyn ee wax soo saarka gudaha ee polypropylene-ka waxqabadka sare leh ee u baahan ku darista wakiilada nucleating-ka iyo kobaca degdegga ah ee baahida loo qabo kala-soocayaasha fududaynta baabuurta iyo baytariyada lithium-ka, waxaa jira awood horumarineed oo ballaaran oo loogu talagalay suuqa wakiilka nucleating-ka ee.
Waxaa jira noocyo badan oowakiilada nukliyeerka, waxqabadkooda badeecaduna wuu sii fiicnaanayaa. Sida laga soo xigtay qaababka kala duwan ee kiristaalka ah ee ay kiciyaan wakiilada nucleating, waxaa loo qaybin karaa wakiilada nucleating α-crystalline iyo wakiilada nucleating β-crystalline. Wakiilada nucleating α-crystalline waxaa loo sii kala saari karaa noocyo aan organic ahayn, organic, iyo polymer ah iyadoo lagu saleynayo kala duwanaanshaha qaab-dhismeedkooda. Wakiilada nucleating aan organic ahayn waxaa inta badan ka mid ah wakiilada nucleating ee hore loo sameeyay sida talc, calcium oxide, iyo mica, kuwaas oo ah kuwo aan qaali ahayn oo si fudud loo heli karo laakiin leh hufnaan liidata iyo dhalaal dusha sare. Wakiilada nucleating dabiiciga ah waxaa inta badan ka mid ah cusbada birta carboxylic acid, cusbada birta fosfate, sorbitol benzaldehyde derivatives, iwm. Kuwaas ka mid ah, sorbitol benzaldehyde derivatives hadda waa wakiilada nucleating ugu bislaaday, oo leh waxqabad aad u fiican iyo qiimo hooseeya, waxayna noqdeen nooca wakiilada nucleating ugu firfircoon, kala duwan, iyo mugga ugu weyn gudaha iyo dibaddaba. Wakiilada nucleating polymer inta badan waa wakiilada nucleating polymeric-barta dhalaalaysa, sida polyvinylcyclohexane iyo polyvinylpentane. Wakiilada nukliyeerka β-crystalline waxay inta badan ka kooban yihiin laba nooc: tiro yar oo iskudhisyo polycyclic ah oo leh qaab-dhismeedyo quasi-planar ah, iyo kuwa ka kooban asiidhyo dicarboxylic ah iyo oksaydhyo, hydroxides, iyo cusbo biraha ah oo ka yimid Kooxda IIA ee jadwalka xilliyeedka. Wakiilada nukliyeerka β-crystalline waxay hubiyaan heerkulka isbeddelka kulaylka ee alaabada iyagoo hagaajinaya iska caabintooda saameynta.
Tusaalooyinka Hawlaha Badeecada iyo Adeegsiga Wakiilada Nukliyeerka
| Badeecadaha | Sharaxaadda Shaqada | Codsiyada |
| Wakiilka Nukliyeerka ee Hufnaanta leh | Waxay si weyn u hagaajin kartaa hufnaanta resin-ka, isagoo yareynaya ceeryaamo ka badan 60%, iyadoo la kordhinayo heerkulka qallooca kulaylka iyo heerkulka kiristaalka ee resin-ka 5 ~ 10℃, iyo hagaajinta module-ka dabacsanaanta 10% ~ 15%. Waxay sidoo kale gaabinaysaa wareegga qaabaynta. waxay kor u qaadaysaa hufnaanta wax soo saarka, waxayna ilaalisaa xasilloonida cabbirka badeecada. | Polypropylene Index Dhalaali Sare (ama Polypropylene Sare MI) |
| Wakiilka Nukliyeerka Adkaysan | Waxay si weyn u hagaajin kartaa sifooyinka farsamada ee resin-ka, iyadoo la kordhinayo modulus-ka dabacsan iyo xoogga foorarsiga oo ka badan 20%, iyo sidoo kale kororka heerkulka qallooca kulaylka 15 ~ 25℃. Waxaa sidoo kale jira horumar dhammaystiran oo dheellitiran oo dhinacyo kala duwan ah sida heerkulka kiristaalka iyo xoogga saameynta, taasoo keentay hoos u dhac dheellitiran iyo hoos u dhac ku yimaada isbeddelka badeecada. | Polypropylene Index-ka Dhalaalaya ee Sare, Adkayn Cusub oo Sare, Adkayn Sare, iyo Kiristaal-celin Sare Polypropylene, Agab Polypropylene ah oo wax laga beddelay oo loogu talagalay Codsiyada Darbiga Khafiifka ah ee Gawaarida |
| Wakiilka Nucleating Adkaynta β-Crystalline | Waxay si wax ku ool ah u kicin kartaa sameynta polypropylene β-crystalline, oo leh heer beddelka β-crystalline oo ka badan 80%, si weyn u hagaajinaya xoogga saameynta ee resin polypropylene, kor u qaadidduna waxay gaari kartaa in ka badan 3 jeer. | Polypropylene Index-ka Dhalaalaya ee Sare, Adkayn Cusub oo Sare, Adkayn Sare, iyo Kiristaal-soo-saar Sare Polypropylene, β-Crystalline Polypropylene |
