Amakuru

"Metallocene" bivuga ibinyabuzima byo guhuza ibyuma kama byakozwe ningingo zinzibacyuho (nka zirconium, titanium, hafnium, nibindi) na cyclopentadiene. Polypropilene ikomatanya hamwe na catalizator yitwa metallocene polypropilene (mPP).

Ibicuruzwa bya metallocene polypropilene (mPP) bifite umuvuduko mwinshi, ubushyuhe bwinshi, inzitizi nyinshi, Ubusobanuro budasanzwe no gukorera mu mucyo, impumuro yo hasi, hamwe nibishobora gukoreshwa muri Fibre, Filime Cast, Injection Molding, Thermoforming, Medical, nibindi. Umusaruro wa metallocene polypropilene (mPP) urimo intambwe nyinshi zingenzi, zirimo gutegura catalizator, polymerisation, na nyuma yo gutunganywa.

1. Gutegura Catalizator:

Guhitamo Catalizike ya Metallocene: Guhitamo catalizator ya metallocene ningirakamaro muguhitamo imiterere ya mPP yavuyemo. Izi catalizike mubisanzwe zirimo ibyuma byinzibacyuho, nka zirconium cyangwa titanium, byashyizwe hagati ya cyclopentadienyl ligands.

Cocatalyst Yongeyeho: Cataliseri ya Metallocene ikoreshwa kenshi ifatanije na cocatalyst, mubisanzwe ikomatanya rya aluminium. Cocatalyst ikora catalizike ya metallocene, ikayemerera gutangiza reaction ya polymerisation.

2. Polymerisation:

Gutegura ibiryo: Propylene, monomer ya polypropilene, mubisanzwe ikoreshwa nkibiryo byambere. Propylene isukuwe kugirango ikureho umwanda ushobora kubangamira inzira ya polymerisation.

Igenamiterere rya reaction: reaction ya polymerisation ibera mumashanyarazi mugihe cyagenzuwe neza. Imiterere ya reaktor irimo catalizike ya metallocene, cocatalyst, nibindi byongeweho bisabwa kubintu bya polymer byifuzwa.

Imiterere ya Polymerisation: Imiterere yimyitwarire, nkubushyuhe, umuvuduko, nigihe cyo gutura, bigenzurwa neza kugirango uburemere bwa molekile bwifuzwa hamwe nuburyo bwa polymer. Cataliseri ya Metallocene ituma igenzura neza neza ibipimo ugereranije na catalizator gakondo.

3. Gukoporora (Bihitamo):

Kwinjiza Co-monomers: Rimwe na rimwe, mPP irashobora gukoporora hamwe nabandi ba monomers kugirango bahindure imitungo yayo. Abaterankunga basanzwe barimo Ethylene cyangwa alfa-olefine. Kwinjizamo ba-monomers byemerera guhitamo polymer kubikorwa byihariye.

4. Guhagarika no kuzimya:

Guhagarika reaction: Iyo polymerisation irangiye, reaction irarangira. Ibi bikunze kugerwaho mugutangiza umukozi wo kurangiza witwara neza hamwe na polymer ikora neza, bigahagarika iterambere.

Kuzimya: Polimeri noneho ikonjeshwa vuba cyangwa ikazimya kugirango hirindwe izindi reaction no gushimangira polymer.

5. Kugarura Polymer no Gutunganya nyuma:

Gutandukanya Polymer: Polimeri yatandukanijwe na reaction ivanze. Monomers idakorewe, ibisigisigi bya catalizator, nibindi bicuruzwa bivanwaho hakoreshejwe uburyo butandukanye bwo gutandukana.

Intambwe Nyuma yo Gutunganya: MPP irashobora kunyuramo izindi ntambwe zo gutunganya, nko gukuramo, guteranya, hamwe na pelletisation, kugirango ugere kumiterere wifuzwa. Izi ntambwe kandi zemerera kwinjiza inyongeramusaruro nkibikoresho byo kunyerera, antioxydants, stabilisateur, nucleating agent, amabara, nibindi byongeweho gutunganya.

Kunoza mPP: Kwibira cyane mubikorwa byingenzi byo gutunganya inyongeramusaruro

Abakozi banyerera. Ibi bifasha kunoza uburyo bwo gusohora no kubumba.

Abongera umuvuduko:Kuzamura ibicuruzwa cyangwa ibikoresho bifasha gutunganya, nkibishashara bya polyethylene, bikoreshwa mugutezimbere gushonga kwa mPP. Izi nyongeramusaruro zigabanya ubukonje kandi zikongerera ubushobozi bwa polymer kuzuza ibibyimba, bikavamo gukora neza.

Antioxydants:

Stabilisateur: Antioxydants ninyongera zingirakamaro zirinda mPP kwangirika mugihe cyo gutunganya. Fenolès zibangamiye na fosifite zikoreshwa cyane muri stabilisateur zibuza ishingwa rya radicals yubuntu, bikarinda kwangirika kwubushyuhe na okiside.

Ibikoresho bya Nucleating:

Ibikoresho bya nucleaux, nka talc cyangwa ibindi bintu bitavanze, byongeweho kugirango biteze imbere imiterere ya kirisiti itondekanye muri mPP. Izi nyongeramusaruro zongerera ibikoresho bya polymer, harimo gukomera no kurwanya ingaruka.

Amabara:

Pigment and Dyes: Amabara akunze kwinjizwa muri mPP kugirango agere kumabara yihariye mubicuruzwa byanyuma. Ibara n'amabara byatoranijwe ukurikije ibara wifuza nibisabwa.

Abahindura Ingaruka:

Elastomers: Mubisabwa aho kurwanya ingaruka ari ngombwa, abahindura ingaruka nka etylene-propylene reberi irashobora kongerwa kuri mPP. Abahindura bahindura ubukana bwa polymer batitanze kubindi bintu.

Abahuza:

Igishushanyo cya Anhydride yumugabo: Compatibilisers irashobora gukoreshwa mugutezimbere ubwuzuzanye hagati ya mPP nizindi polymers cyangwa inyongeramusaruro. Umugabo wa anhydride wigitsina gabo, kurugero, urashobora kongera imbaraga hagati yibice bitandukanye bya polymer.

Ibikoresho bya Slip na Antiblock:

Ibikoresho byo kunyerera: Usibye kugabanya guterana amagambo, ibikoresho byo kunyerera birashobora no gukora nka anti-block. Ibikoresho bya Antiblock birinda gufatana hamwe na firime cyangwa urupapuro mugihe cyo kubika.

. umusaruro wa mPP utanga urwego rwinyongera rwo kugenzura no gutomora, kwemerera kwinjiza inyongeramusaruro muburyo bushobora guhuzwa neza kugirango byuzuze ibisabwa byihariye.)

Gufungura neza丨Ibisubizo bishya kuri mPP: Uruhare rwinyongera zitunganyirizwa, Ibyo abakora mPP bakeneye kumenya!

mPP yagaragaye nka polymer yimpinduramatwara, itanga imitungo yongerewe imikorere inoze mubikorwa bitandukanye. Nyamara, ibanga ryihishe inyuma ntirishingiye gusa kubiranga ahubwo no muburyo bwo gukoresha ingamba zo gutunganya ibintu byongeweho.

SILIMER 5091itangiza uburyo bushya bwo kuzamura imikorere ya metallocene polypropilene, itanga ubundi buryo bukomeye bwinyongera bwa PPA, hamwe nigisubizo cyo gukuraho inyongeramusaruro zishingiye kuri fluor imbogamizi za PFAS.

SILIMER 5091ni Fluorine idafite Polymer itunganya inyongeramusaruro yo gukuramo ibikoresho bya polypropilene hamwe na PP nkubwikorezi bwatangijwe na SILIKE. Nibicuruzwa byahinduwe bya polysiloxane masterbatch ibicuruzwa, bishobora kwimukira mubikoresho bitunganyirizwa kandi bikagira ingaruka mugihe cyo gutunganya hifashishijwe uburyo bwiza bwo gusiga amavuta ya polysiloxane ningaruka za polarite yitsinda ryahinduwe. Umubare muto wa dosiye urashobora kunoza neza gutembera no gutunganywa, kugabanya gupfa mugihe cyo kuyisohora, no kunoza ibintu byuruhu rwikigina, bikoreshwa cyane mugutezimbere amavuta nubuso buranga plastike.

IgiheImfashanyigisho ya PFAS Yubusa (PPA) SILIMER 5091yinjijwe muri matrise ya metallocene polypropilene (mPP), itezimbere umuvuduko wa mPP, igabanya ubushyamirane hagati yiminyururu ya polymer, kandi ikarinda gukomera mugihe cyo kuyitunganya. Ibi bifasha kunoza uburyo bwo gusohora no kubumba. koroshya inzira yumusaruro yoroshye no gutanga umusanzu mubikorwa rusange.
