"Metallocene" waxaa loola jeedaa xeryahooda isuduwaha birta ee aasaasay ee ay sameeyeen biraha kala-guurka (sida zirconium, itanium, Hafniium, iwm) iyo Cyclopentadine. Polypropylenes Synthens oo leh cunsuriyada metlocene waxaa loo yaqaan 'Metlocene Polypropylen' (MPP).

Alaabada 'Metlocene Polypropylen' Soosaarka metleocene polypropylen (MPP) waxay ku lug leedahay dhowr talaabo oo muhiim ah, oo ay ku jiraan diyaarinta wax lagu diyaariyo, polymooremization, iyo ka dib.

1. Diyaarinta Diyaarinta:

Xulashada itaaltent Metlatocent: Xulashada Mactale-ka Metlallocent ayaa muhiim u ah go'aaminta sifooyinka MPP-da natiijada ka dhalatay. Kuwaas daadashadan ayaa sida caadiga ah ku lug leh biraha kala-guurka, sida zirtonium ama titanium, oo ay weheliyaan inta u dhexeysa marinka adag ee Cyclopentadiens.

Intaas waxaa isu keena Coctuclocensts: Istaatent-ka Metallocene waxaa badanaa loo isticmaalaa iyadoo lala kaashanayo cocatyst, sida caadiga ah xarun ku saleysan aluminium. Cocatyst-ka wuxuu shaqeynayaa kadhiga metlocene, taasoo u oggolaaneysa in ay bilaabaan falcelinta polymerization.

2. Signabixinta polymarization:

Diyaarinta Quudinta Propylence-ka ayaa la nadiifiyaa si looga saaro cilado aan faragelin ku yeelan karo hannaanka polymomanmization.

Dib-u-soo-nooleynta: Falcelinta polymerization-ka ayaa ka dhacaya in lagu helo falcelin si taxaddar leh loo xakameeyo xaaladaha. Dejinta dib-u-habeeyaha waxaa ka mid ah cunsuriyada metlocene, cocatlyst, iyo waxyaabaha kale ee lagu daro ee looga baahan yahay guryaha polymer ee la rabay.

Shuruudaha polymerization: xaaladaha fal-celinta, sida heerkulka, cadaadiska, iyo waqtiga deganaanshaha, waxaa si taxaddar leh loo xakameeyaa si loo hubiyo in miisaanka modol-maylka la doonayo iyo qaab-dhismeedka polymer. Qalalaasaha Metallocene waxay awood u siisaa xakameyn sax ah oo ka badan cabirradan marka loo barbar dhigo cuntooyinka dhaqanka.

3. Soo-bandhigida (ikhtiyaari):

Iska dhex-darida wadashaqeeyayaasha: Xaaladaha qaarkood, MPP waxaa laga yaabaa inay codkaatoro monomers kale si ay wax uga beddelaan guryahooda. Wadashaqeynta wadajirka ah ee wadajirka ah waxaa ku jira ethylene ama alfa-oleffins alfa-oleffins. Isku-darka la-hawlgalayaasha iskaashatada waxay u oggolaaneysaa in la dhiso polymer si loo helo codsiyo gaar ah.

4. Joojinta iyo sunta:

Joojinta falcelinta: Mar alla markii la dhammeeyo polymeration-ka si loo dhammeeyo, falcelinta waa la joojiyaa. Tan waxaa badanaa lagu guuleystaa iyadoo la soo bandhigayo wakiilka joojinta oo ka falcelinaya silsiladda polymer firfircoon, joojinta koritaanka kale.

Daloof: Polymer-ka ayaa markaa si dhakhso ah loo qaboojiyaa ama loo daadanayaa si looga hortago falcelin dheeri ah oo lagu xoojiyo polymer.

5. Soo kabashada polymer iyo ka dib markii la wado:

Kala goynta polymer: polymer-ka ayaa laga soocayaa isku-darka jawaab celinta. Monomers-ka aan la-darin, haraaga haraaga, iyo badeecadaha kale ee wax soo saarta ayaa laga saaraa farsamooyinka kala-goynta kala duwan.

Talaabooyinka Kadib Tallaabooyinkan ayaa waliba u oggolaanaya isku darka waxyaabaha lagu daro sida wakiilada wareega, antioxidas, xasilinta, xubnaha naafo, iyo waxyaabaha kale ee lagu daro.

U fiirsashada MPP: quusin qoto dheer oo loogu talagalay doorka muhiimka ah ee lagu daro lagu daro

Wakiilada Gawaarida: Wakiilada ku-wareejinta, sida dufanka muddada-dheer ee dufanka badan, waxaa badanaa lagu daraa MPP si loo yareeyo kala-goynta u dhexeeya silsiladaha polymer, ka hortagga ku dhejinta inta lagu gudajiro. Tani waxay gacan ka geysaneysaa hagaajinta soo-saarista iyo geedi socodka qaaradaha.

Xirmooyinka qulqulka:Qulqulka qulqulka ama aaladda aaladaha, sida wax lagu qodo qangayo polyetylen, ayaa loo isticmaalaa in lagu hagaajiyo qulqulka dhalaalay ee MPP. Kuwa wax lagu daro waxay yareeyaan vaccosity waxayna kor u qaadeen awoodda polymer-ka ee buuxinta godadka caarada, taasoo dhalisay in si fiican wax looga qabto.

Antioxidants:

SASO SOS: Antioxidants-ka waa wax lagu daro waxyaabaha lagu daro ee ka ilaalinaya MPP-da nabaad-guurka inta lagu gudajiro. Cagade nuglays iyo Phosphites-ka waxaa si caadi ah loo istcimaalaa xasilloonida in la xakameeyo samaynta xagjiriinta bilaashka ah, ka hortagga xaalada kuleylka iyo oxida.

Wakiilada Nucaleating:

Wakiilada Nuceating, sida Talac ama xeryahooda kale ee Inorganic, ayaa lagu daray si kor loogu qaado dhismaha qaab dhismeedka dalxiiska ee loo dalbaday ee MPP-da. Kuwaas waxaa lagu xoojiyaa guryaha farsamada gacanta ee polymer, oo ay kujirto adkaanta iyo iska caabin saamaynta saamiga.

Miyirka:

Doofaarka iyo dawada: midabayaasha ayaa badanaa lagu dhex daraa MPP si ay u gaaraan midabyo gaar ah oo ku jira sheyga ugu dambeeya. Doofaarka iyo geedhada ayaa loo xushay iyadoo lagu saleynayo midabka la doonayo iyo shuruudaha dalabka.

Beddelka Saamaynta:

Edallogars: Codsiyada ay iska caabbinta saafiga ahi muhiim u tahay, ganacsatada saameynta sida cudurka 'propylene-propylemen' ayaa lagu dari karaa MPP. Isticmaalkan is-beddelka ah waxay horumariyaan xoogga adag ee polymer iyada oo aan allabaryo guryaha kale.

Compatibbbiles:

Lab anhydride-ga leh Gawaarida: Compatibiles-ka waxaa loo isticmaali karaa in lagu wanaajiyo is-waafajinta ka dhaxaysa MPP iyo pomoomer kale ama waxyaabo lagu daro. Beeraha camalka leh ee cajiibka ah, tusaale ahaan, waxay kor u qaadi kartaa aqalka u dhexeeya qaybaha polymer ee kaladuwan.

Wareegtada la-dagaallanka iyo antintalock:

Wakiilada wareega: Marka lagu daro yareynta khilaafaadka, wakiillada la soo qaaday waxay sidoo kale u dhaqmi karaan wakiilo ka soo horjeedka anti-hot-ka. Wakiilada ka hortagga antiblock waxay ka hortagaan ku dhejinta filimka ama sagxadaha xaashida inta lagu jiro kaydinta.

(Waa muhiim in la ogaado in waxyaabaha lagu daro ee lagu daro qaab dhismeedka MPP ay ku kala duwanaan karto iyadoo lagu saleynayo heerka wax soo saarka ee soosaarka ah si loo helo si aad u ah isku-darka siyaadooyinka si aad u jilicsan si loo buuxiyo shuruudaha gaarka ah si loo buuxiyo shuruudaha gaarka ah.)

Waxtarka furitaanka丨Xallinta hal-abuurka ah ee MPP: Doorka lagu daro ka-hortagga sheeko sheekada, Soo-saareyaasha MPP-ga ee u baahan inay ogaadaan!

Ururka MPP wuxuu u soo muuqday inuu yahay polymer kacaan kacaan ah, oo bixiya guryo la xoojiyey oo la wanaajiyo dalabyada kala duwan ee codsiyada kala duwan. Si kastaba ha noqotee, sirta ka dambaysa guusheedii ma aha oo kaliya kuma jiraan astaamaha dhaxalka ah laakiin sidoo kale ku jirta adeegsiga istiraatiijiyadeed ee lagu daro ka-hortagga.

Silimer 5091waxay soo bandhigaysaa qaab hal-abuurnimo ah oo kor loogu qaadayo basaasiga ah ee 'Metallocene Polypropylene', oo bixiya badal qasab ah oo ku qasban kuwa dhaqanka ah ee PPA-ga, iyo xalka lagu baabi'iyo waxyaabaha lagu daro ku-saleysan ee ku saleysan caqabadaha PFAS.
