Wakiilka Nukliyeerku waa nooc cusub oo wax lagu daro ah oo hagaajin kara sifooyinka jirka iyo farsamada ee alaabta sida daahfurnaanta, dhalaalka dusha sare, xoogga xajinta, qallafsanaanta, heerkulka kulaylka, caabbinta saameynta, caabbinta gurguurta, iwm. . Waxaa si weyn loogu isticmaalaa habka wax soo saarka ee balaastikada crystalline aan dhamaystirnayn sida polyetylen iyo polypropylene ee baabuurta, qalabka guriga, cuntada, elektarooniga ah, iyo beeraha caafimaadka. Tusaale ahaan, wakiilka nukliyeerka ayaa ah shay muhiim ah oo soo saara xabagta waxqabadka sare leh sida polypropylene index dhalaalaysa sare, adag cusub, adkeysi sare, iyo polypropylene-crystalline-sare, β-crystalline polypropylene, iyo alaabta polypropylene la beddelay ee baabuurta. codsiyada derbi-dhuuban. Marka lagu daro walxo nukleye ah oo gaar ah, resins leh hufnaan, qallafsanaan, iyo adag ayaa la soo saari karaa. Iyada oo kororka la taaban karo ee wax soo saarka gudaha ee polypropylene waxqabadka sare leh ee u baahan in lagu daro wakiilada nuclei-ka iyo kobaca degdega ah ee baahida loo qabo khafiifinta baabuurta iyo kala-soocida baytariyada lithium, waxaa jira horumar balaadhan oo horumarineed oo loogu talagalay suuqa wakiilka nukliyeerka.
Waxaa jira noocyo badan oo ka mid ahwakiilada nukliyeerka, iyo wax qabadkooda wax soo saarkoodu wuu sii socdaa. Marka loo eego qaababka kala duwan ee crystal ee ay keeneen wakiilada nukleating, waxaa loo qaybin karaa α-crystalline nucleating agents iyo β-crystalline nucleating agents. Iyo α-crystalline nucleating agents waxa lagu sii kala saari karaa noocyo aan organic, organic, iyo polymer oo ku salaysan kala duwanaanshahooda qaabdhismeed. Waxyaalaha nukliyeerka ah ee aan noolaha lahayn inta badan waxaa ka mid ah wakiilada nuclei-ka ee hore u soo baxay sida talc, calcium oxide, iyo mica, kuwaas oo ah kuwo aan qaali ahayn oo sahlan in la helo laakiin leh hufnaan liidata iyo dhalaalka dusha sare. Walxaha nukliyeerka dabiiciga ah inta badan waxaa ka mid ah cusbada birta ah ee karboksilic acid, cusbada birta fosfat, sorbitol benzaldehyde derivatives, iwm. Waxaa ka mid ah, sorbitol benzaldehyde derivatives ayaa hadda ah wakiilada nukleating ugu bislaaday, oo leh waxqabad aad u fiican iyo qiimo jaban, waxayna noqdeen kuwa ugu firfircoon ee horumarsan, kala duwan. , iyo nooca mugga ugu weyn ee wakiilada nukliyeerka gudaha iyo dibaddaba. Waxyaalaha nukliyeerka ah ee polymer-ka ah ayaa inta badan ah wakiilada nukliyeerka polymeric-ku-dhalan-sare, sida polyvinylcyclohexane iyo polyvinylpentane. β-crystalline nucleating wakiilada inta badan waxay ka kooban yihiin laba nooc: tiro yar oo xeryahooda polycyclic ah oo leh qaab-dhismeedka quasi-planar, iyo kuwa ka kooban qaar ka mid ah acids dicarboxylic iyo oxides, hydroxides, iyo cusbada biraha ee Kooxda IIA ee miiska xilliyeedka. β-crystalline nucleating wakiilada waxay xaqiijiyaan heerkulka qallafsanaanta kulaylka ee alaabada iyagoo hagaajinaya caabbinta saameyntooda.
Tusaalooyinka Hawlaha Alaabta iyo Codsiga Wakiilada Nukliyeerka
Alaabta | Sharaxaada Shaqada | Codsiyada |
Wakiilka Nukliyeerka ee daahfuran | Waxay si weyn u wanaajin kartaa daahfurnaanta xabagta xabagta, taasoo yaraynaysa ceecada in ka badan 60%, iyada oo la kordhinayo heerkulka kulaylka qallooca iyo heerkulka crystallization 5-10 digrii oo cusbo ah, iyo hagaajinta moodeelka dabacsanaanta 10% ~ 15%. Waxa kale oo ay gaabinaysaa wareegga qaabaynta, waxay kordhisaa waxtarka wax soo saarka, waxayna ilaalisaa xasiloonida cabbirka alaabta. | Heerka dhalaalidda sare ee Polypropylene (ama High MI Polypropylene) |
Adkeynta Wakiilka Nukliyeerka | Waxay si weyn u wanaajin kartaa sifooyinka farsamada ee resin, kororka moodeelka dabacsanaanta iyo xoogga foorarsiga oo ka badan 20%, iyo sidoo kale kororka heerkulka qallooca kulka 15 ~ 25 ℃. Waxa kale oo jira horumar dhammaystiran oo dheellitiran oo dhinacyo kala duwan ah sida heerkulka crystallization iyo xoogga saamaynta, taasoo keentay hoos u dhac dheeli tiran iyo hoos u dhac ku yimaada bogag-wareedka badeecada. | Tilmaamaha Sare ee Polypropylene, Qallafsanaan Sare oo Cusub, Adag-sare, iyo Polypropylene-Crystallization-sare, Qalabka Polypropylene ee La Habeeyay ee Codsiyada Qalab-Darabka Gawaadhida |
β-Crystalline Adkeynta Wakiilka Nukliyeerka | Waxay si hufan u kicin kartaa samaynta β-crystalline polypropylene, oo leh heerka beddelka β-crystalline in ka badan 80%, si weyn u wanaajinaya awoodda saamaynta xabagta polypropylene, kor u qaadistuna waxay gaari kartaa in ka badan 3 jeer. | Tusmada dhalaalaysa Polypropylene, Qallafsanaan Cusub oo Cusub, Adag-sare, iyo Polypropylene-Crystallization Sare, β-Crystalline Polypropylene |
