Amakuru

“Metallocene” yerekeza ku bintu bihuza ibyuma bikomoka ku byuma bihinduka (nk'ibiziriko, titaniyumu, hafnium, nibindi) na cyclopentadiene. Polypropylene ikorwa na metallocene catalysts yitwa metallocene polypropylene (mPP).

Ibicuruzwa bya Metallocene polypropylene (mPP) bifite amazi menshi, ubushyuhe bwinshi, imbogamizi nyinshi, imiterere idasanzwe kandi igaragara neza, impumuro nke, kandi bishobora gukoreshwa muri Fibres, Cast Film, Injection Molding, Thermoforming, Medical, n'ibindi. Gukora metallocene polypropylene (mPP) bikubiyemo intambwe nyinshi z'ingenzi, harimo gutegura catalyst, polymerization, no gutunganya nyuma.

1. Gutegura Katalisiti:

Guhitamo Metallocene Catalyst: Guhitamo metallocene catalyst ni ingenzi mu kugena imiterere ya mPP ivamo. Izi catalysts akenshi ziba zirimo ibyuma bihinduka, nka zirconium cyangwa titanium, biri hagati ya ligande za cyclopentadienyl.

Kongeramo Cocatalyst: Katalyst za Metallocene zikunze gukoreshwa hamwe na cocatalyst, akenshi ikoreshwa muri aluminiyumu. Cocatalyst ikora katalyst ya metallocene, bigatuma itangiza reaction ya polymerization.

2. Guhindura imiterere y'ibintu mu buryo bwa polimeri:

Gutegura ibiryo: Propylene, monomer ya polypropylene, ikunze gukoreshwa nk'ibiryo by'ibanze. Propylene irasukurwa kugira ngo ikurweho imyanda ishobora kubangamira inzira yo gupolima.

Imiterere ya Reactor: Uburyo bwo gukora polymerization buba muri reactor mu gihe hagenzuwe neza. Imiterere ya reactor irimo metallocene catalyst, cocatalyst, n'ibindi bikoresho bikenewe kugira ngo polymer ikore neza.

Imiterere ya polymerization: Imiterere y'ibizamini, nk'ubushyuhe, igitutu, n'igihe cyo gutura, bigenzurwa neza kugira ngo harebwe uburemere bwa molekile n'imiterere ya polymer. Katalyst za Metallocene zituma habaho kugenzura neza ibi bipimo ugereranije na katalyst zisanzwe.

3. Kopolimeri (Uburyo bwo guhitamo):

Kwinjizwa kwa Co-monomer: Hari ubwo mPP ishobora gushyirwaho copolymer hamwe n'izindi monomer kugira ngo ihindure imiterere yayo. Co-monomer zisanzwe zirimo ethylene cyangwa izindi alpha-olefini. Kwinjizwa kwa co-monomer bituma polima ihinduka kugira ngo ikoreshwe mu buryo bwihariye.

4. Guhagarika no Kuzimya:

Guhagarika ibikorwa: Iyo polymerization irangiye, ibyo bikorwa birahagarara. Ibi akenshi bigerwaho hakoreshejwe uburyo bwo guhagarika ibikorwa bukorana n'impera z'uruhererekane rwa polymer, bigahagarika iterambere ry'ibindi bikorwa.

Kuzimya: Hanyuma polimeri ikonjeshwa vuba cyangwa igashira kugira ngo hirindwe ko habaho ibindi bibazo no gukomeza polimeri.

5. Gusubiza no gutunganya polymer nyuma yo kuyitunganya:

Gutandukanya polymer: polymer itandukanyijwe n'uruvange rw'ibisubizo. Monomer zitarakorwa, ibisigazwa bya catalyst, n'ibindi bivamo bikurwaho hakoreshejwe uburyo butandukanye bwo gutandukanya.

Intambwe zo Gutunganya Nyuma: MPP ishobora kunyura mu ntambwe z'inyongera zo gutunganya, nko gusohora, gukurura, no gukurura, kugira ngo igere ku miterere n'imiterere byifuzwa. Izi ntambwe kandi zemerera gushyirwamo inyongeramusaruro nka slip agents, antioxydants, stabilizers, nucleating agents, colorants, n'izindi nyongeramusaruro zo gutunganya.

Gukoresha neza mPP: Gusobanukirwa byimbitse inshingano z'ingenzi zo gutunganya inyongeramusaruro

Abakora ibikoresho byo gusimbuka: Ibintu bitera gucika intege, nka za amide zirimo ibinure birebire, bikunze kongerwa muri mPP kugira ngo bigabanye ukutumvikana hagati y’iminyururu ya polymer, bikarinda gufatana mu gihe cyo kuyitunganya. Ibi bifasha kunoza inzira zo gusohora no kuyibumba.

Ibikoresho bitera imbaraga mu mikorere y'amazi:Ibikoresho bifasha mu kunoza imikorere y'amazi cyangwa ibikoresho byo gutunganya, nk'ibishishwa bya polyethylene, bikoreshwa mu kunoza imikorere y'amazi ya mPP. Ibi binyongerera bigabanya ubukana bw'amazi kandi bikongera ubushobozi bwa polymer bwo kuzuza imyobo y'ibihumyo, bigatuma birushaho gutunganywa neza.

Antioxydants:

Ibikomeza Guhagarara: Antioxydants ni inyongeramusaruro z'ingenzi zirinda mPP kwangirika mu gihe cyo gutunganya. Fenoli na fosfite zitinda gukoreshwa cyane ni ibikomeza guhagarara bibuza ikorwa rya radicals yigenga, bikarinda kwangirika k'ubushyuhe n'ubudahangarwa bw'umwuka.

Ibintu bitera imiterere y'umubiri:

Ibintu bitera imbaraga, nka talc cyangwa ibindi bintu bidafite umwimerere, byongerwamo kugira ngo biteze imbere ikorwa ry’imiterere ya kristali itunganijwe neza muri mPP. Ibi binyongerera imbaraga imikorere ya polymer, harimo gukomera no kudakora neza.

Amarangi:

Amabara n'irangi: Amabara akunze gushyirwa muri mPP kugira ngo haboneke amabara yihariye mu gicuruzwa cya nyuma. Amabara n'irangi bitoranywa hashingiwe ku ibara ryifuzwa n'ibisabwa mu ikoreshwa.

Ibihindura ingaruka:

Elastome: Mu bikorwa aho ubudahangarwa bw'ingaruka ari ingenzi, ibikoresho bihindura ingaruka nka ethylene-propylene rubber bishobora kongerwa kuri mPP. Ibi bikoresho bihindura ibintu byongera ubukana bwa polymeri bitagize ingaruka ku zindi ngaruka.

Ibihuza:

Uduce twa Anhydride ya Maleic: Uduce duhuza ibintu dushobora gukoreshwa mu kunoza imikoranire hagati ya mPP n'izindi polymer cyangwa inyongeramusaruro. Urugero, uduce twa anhydride ya Maleic dushobora kongera ubufatanye hagati y'ibice bitandukanye bya polymer.

Imiti igabanya ubukana n'imiti igabanya ubukana bw'indwara:

Imiti igabanya ubushyuhe: Uretse kugabanya ubushyuhe, imiti igabanya ubushyuhe ishobora no gukora nk'imiti irwanya ubushyuhe. Imiti irwanya ubushyuhe ibuza ko filime cyangwa impapuro zifatana mu gihe cyo kubika.

(Ni ngombwa kumenya ko inyongeramusaruro zikoreshwa mu gutunganya mPP zishobora gutandukana bitewe n'ikoreshwa ryazo, imiterere y'itunganywa, n'imiterere y'ibikoresho byifuzwa. Abakora bahitamo neza izi nyongeramusaruro kugira ngo bagere ku musaruro mwiza. Gukoresha metallocene catalysts mu gukora mPP bitanga urwego rw'inyongera rwo kugenzura no gukoresha neza, bigatuma inyongeramusaruro zishyirwa mu buryo bunoze kugira ngo zihuze n'ibikenewe byihariye.)

Gufungura neza丨Ibisubizo bishya kuri mPP: Uruhare rw'inyongera nshya zo gutunganyaIcyo abakora mPP bakeneye kumenya!

mPP yagaragaye nk'umusemburo w'umwimerere, itanga imiterere myiza n'imikorere myiza mu bikorwa bitandukanye. Ariko, ibanga ry'intsinzi yayo ntirishingiye gusa ku miterere yayo bwite ahubwo rinashingiye ku ikoreshwa ry'inyongera zigezweho mu gutunganya ibintu.

SILIMER 5091izana uburyo bushya bwo kuzamura ubushobozi bwo gutunganya polypropylene ya metallocene, itanga ubundi buryo bushimishije bwo gusimbura inyongeramusaruro za PPA zisanzwe, hamwe n'ibisubizo byo gukuraho inyongeramusaruro zishingiye kuri fluorine hakurikijwe amabwiriza ya PFAS.

SILIMER 5091ni inyongeramusaruro idafite fluorine yo gusohora ibikoresho bya polypropylene hamwe na PP nk'umutwaro watangijwe na SILIKE. Ni umusaruro wa polysiloxane masterbatch wahinduwe mu buryo bw'umwimerere, ushobora kwimukira mu bikoresho bitunganya kandi ukagira ingaruka mu gihe cyo gutunganya hakoreshejwe ingaruka nziza zo gusiga amavuta za polysiloxane ndetse n'ingaruka za polarity z'amatsinda yahinduwe. Ingano nto y'ingano ishobora kongera uburyo bwo gusuka amazi no gutunganya neza, ikagabanya amarira y'amaraso mu gihe cyo gusohora, kandi ikanoza imiterere y'uruhu rw'ifi, ikoreshwa cyane mu kunoza uburyo bwo gusiga amavuta n'imiterere y'ubuso bw'isuka rya plastiki.

IgiheUbufasha bwo gutunganya polymeri budafite PFAS (PPAS) SILIMER 5091ishyirwa muri metallocene polypropylene (mPP) matrix, irushaho kunoza uburyo mPP ishongesha, igabanya ubukana hagati y’iminyururu ya polymer, kandi ikarinda gufatana mu gihe cyo kuyitunganya. Ibi bifasha kunoza inzira zo gusohora no kuyitunganya, bikoroshya inzira zo gukora neza no kugira uruhare mu mikorere myiza muri rusange.
