"Metallocene" imatanthauza zinthu zopangidwa ndi zitsulo zopangidwa ndi zitsulo zosinthika (monga zirconium, titanium, hafnium, ndi zina zotero) ndi cyclopentadiene. Polypropylene yopangidwa ndi zitsulo zoyambitsa metallocene imatchedwa metallocene polypropylene (mPP).

Zinthu zopangidwa ndi Metallocene polypropylene (mPP) zimakhala ndi kuyenda bwino, kutentha kwambiri, chotchinga chachikulu, Kumveka bwino komanso Kuwonekera bwino, fungo lochepa, komanso kugwiritsa ntchito bwino mu Fibers, Cast Film, Injection Molding, Thermoforming, Medical, ndi Zina. Kupanga kwa metallocene polypropylene (mPP) kumaphatikizapo masitepe angapo ofunikira, kuphatikizapo kukonzekera catalyst, polymerization, ndi post-processing.

1. Kukonzekera kwa Catalyst:

Kusankha Metallocene Catalyst: Kusankha metallocene catalyst ndikofunikira kwambiri podziwa momwe mPP imagwirira ntchito. Ma catalyst amenewa nthawi zambiri amakhala ndi zitsulo zosinthira, monga zirconium kapena titanium, zomwe zimakhala pakati pa ma cyclopentadienyl ligands.

Kuwonjezera pa Cocatalyst: Ma catalyst a Metallocene nthawi zambiri amagwiritsidwa ntchito limodzi ndi cocatalyst, yomwe nthawi zambiri imakhala yopangidwa ndi aluminiyamu. Cocatalyst imayambitsa metallocene catalyst, zomwe zimapangitsa kuti iyambe polymerization reaction.

2. Kupopera:

Kukonzekera Zakudya: Propylene, monomer ya polypropylene, nthawi zambiri imagwiritsidwa ntchito ngati chakudya chachikulu. Propylene imayeretsedwa kuti ichotse zinyalala zomwe zingasokoneze njira yopangira polymerization.

Kukhazikitsa kwa Reactor: Kuyankha kwa polymerization kumachitika mu reactor pansi pa mikhalidwe yoyang'aniridwa mosamala. Kukhazikitsa kwa reactor kumaphatikizapo metallocene catalyst, cocatalyst, ndi zina zowonjezera zomwe zimafunikira pamtundu wa polima womwe ukufunika.

Mikhalidwe ya Polymerization: Mikhalidwe ya reaction, monga kutentha, kupanikizika, ndi nthawi yokhalamo, imawongoleredwa mosamala kuti zitsimikizire kulemera kwa mamolekyulu ndi kapangidwe ka polima komwe kumafunidwa. Ma metallocene catalysts amalola kuwongolera molondola kwambiri magawo awa poyerekeza ndi ma catalysts achikhalidwe.

3. Kukonza zinthu pogwiritsa ntchito polymer (ngati mukufuna):

Kuphatikiza kwa Co-monomers: Nthawi zina, mPP ikhoza kupangidwa ndi copolymer ndi ma monomers ena kuti isinthe mawonekedwe ake. Ma co-monomers wamba amaphatikizapo ethylene kapena ma alpha-olefins ena. Kuphatikiza kwa ma co-monomers kumalola kusintha kwa polima kuti igwiritsidwe ntchito mwanjira inayake.

4. Kuthetsa ndi Kuzimitsa:

Kutha kwa Chiyambukiro: Kutha kwa polymerization kukatha, chiyambukirocho chimatha. Izi nthawi zambiri zimachitika poika chothetsera chomwe chimagwira ntchito ndi malekezero a unyolo wa polymer, ndikuletsa kukula kwina.

Kuzimitsa: Kenako polima imaziziritsidwa kapena kuzimitsidwa mwachangu kuti isachitikenso komanso kuti polimayo ikhale yolimba.

5. Kubwezeretsa ndi Kukonza Polima Pambuyo pa Polima:

Kulekanitsa Polima: Polima imalekanitsidwa ndi kusakaniza kwa reaction. Ma monomers osakhudzidwa, zotsalira za catalyst, ndi zina zotsala zimachotsedwa kudzera mu njira zosiyanasiyana zolekanitsa.

Masitepe Okonza Pambuyo: MPP ikhoza kudutsa masitepe ena okonza, monga kutulutsa, kuphatikiza, ndi kuyika pelletization, kuti ikwaniritse mawonekedwe ndi makhalidwe omwe mukufuna. Masitepe awa amalolanso kuphatikiza zowonjezera monga zotsekemera, ma antioxidants, zokhazikika, zotulutsa nucleating, colorants, ndi zina zowonjezera pakupanga.

Kukonza mPP: Kuphunzira Kwambiri za Ntchito Zofunikira pa Zowonjezera Zopangira

Othandizira Otsetsereka: Zothandizira kutsetsereka, monga ma amide amafuta a unyolo wautali, nthawi zambiri zimawonjezeredwa ku mPP kuti zichepetse kukangana pakati pa unyolo wa polima, zomwe zimaletsa kumatirira panthawi yokonza. Izi zimathandiza kukonza njira zotulutsira ndi kuumba.

Zothandizira Kuyenda kwa Madzi:Zowonjezera mphamvu ya madzi kapena zothandizira kukonza, monga ma sera a polyethylene, zimagwiritsidwa ntchito kukonza kayendedwe ka mPP. Zowonjezera izi zimachepetsa kukhuthala ndikuwongolera luso la polima lodzaza mabowo a nkhungu, zomwe zimapangitsa kuti ntchito yake ikhale yosavuta.

Ma antioxidants:

Zokhazikika: Ma antioxidants ndi zowonjezera zofunika zomwe zimateteza mPP kuti isawonongeke panthawi yokonza. Ma phenols ndi ma phosphites oletsedwa nthawi zambiri amagwiritsidwa ntchito ngati zokhazikika zomwe zimaletsa kupanga ma free radicals, kupewa kuwonongeka kwa kutentha ndi okosijeni.

Zinthu Zopangira Nucleating:

Zinthu zopangira ma nucleating, monga talc kapena zinthu zina zosapangidwa, zimawonjezedwa kuti zilimbikitse mapangidwe a kristalo wokonzedwa bwino mu mPP. Zowonjezera izi zimawonjezera mphamvu za makina a polima, kuphatikizapo kuuma ndi kukana kugunda.

Zopaka utoto:

Utoto ndi Utoto: Zopaka utoto nthawi zambiri zimaphatikizidwa mu mPP kuti zipange mitundu inayake mu chinthu chomaliza. Utoto ndi utoto zimasankhidwa kutengera mtundu womwe mukufuna komanso zofunikira pakugwiritsa ntchito.

Zosintha Zotsatira:

Ma Elastomer: Mu ntchito zomwe kukana kukhudzidwa ndikofunikira kwambiri, zosinthira kukhudzidwa monga rabara ya ethylene-propylene zitha kuwonjezeredwa ku mPP. Zosinthira izi zimathandizira kulimba kwa polima popanda kuwononga zinthu zina.

Zogwirizana:

Maleic Anhydride Grafts: Ma compatibilizers angagwiritsidwe ntchito kukonza kugwirizana pakati pa mPP ndi ma polima ena kapena zowonjezera. Maleic anhydride grafts, mwachitsanzo, amatha kuwonjezera kugwirizana pakati pa zigawo zosiyanasiyana za polima.

Mankhwala Oletsa Kutsekeka ndi Oletsa Kutsekeka:

Zinthu Zothira Madzi: Kuwonjezera pa kuchepetsa kukangana, zinthu zothira madzi zimathanso kugwira ntchito ngati zinthu zothira madzi. Zinthu zothira madzi zimaletsa kuti filimu kapena mapepala azimatirira pamodzi panthawi yosungira.

(Ndikofunikira kudziwa kuti zowonjezera zomwe zimagwiritsidwa ntchito popanga mPP zimatha kusiyana kutengera momwe zimagwiritsidwira ntchito, momwe zimagwiritsidwira ntchito, komanso zinthu zomwe zimafunidwa. Opanga amasankha mosamala zowonjezerazi kuti akwaniritse bwino ntchito yomaliza. Kugwiritsa ntchito metallocene catalysts popanga mPP kumapereka mulingo wowonjezera wowongolera komanso wolondola, zomwe zimathandiza kuti zowonjezera ziphatikizidwe m'njira yomwe ingakonzedwe bwino kuti ikwaniritse zofunikira zinazake.)

Kutsegula Bwino丨Mayankho Atsopano a mPP: Udindo wa Zowonjezera Zatsopano ZopangiraZimene opanga mPP ayenera kudziwa!

MPP yakhala ngati polima yosintha zinthu, yopereka mphamvu zowonjezera komanso magwiridwe antchito abwino m'njira zosiyanasiyana. Komabe, chinsinsi cha kupambana kwake sichili m'makhalidwe ake enieni okha komanso mukugwiritsa ntchito bwino zowonjezera zamakono.

SILIMER 5091imayambitsa njira yatsopano yokwezera kuthekera kwa metallocene polypropylene kukonzedwa, kupereka njira ina yabwino kwambiri m'malo mwa zowonjezera zachikhalidwe za PPA, ndi njira zothetsera zowonjezera zochokera ku fluorine pansi pa zoletsa za PFAS.

SILIMER 5091Ndi chowonjezera cha polymer chopanda fluorine chomwe chimagwiritsidwa ntchito pochotsa zinthu za polypropylene ndi PP ngati chonyamulira chomwe chinayambitsidwa ndi SILIKE. Ndi chinthu cha polysiloxane masterbatch chosinthidwa mwachilengedwe, chomwe chingasunthire ku zida zokonzera ndikukhala ndi mphamvu panthawi yokonza pogwiritsa ntchito mphamvu yabwino kwambiri yoyambira ya polysiloxane komanso mphamvu ya polarity ya magulu osinthidwa. Mlingo wochepa ungathandize kusintha kusinthasintha ndi kusinthasintha, kuchepetsa kutaya madzi panthawi yotulutsa, ndikukonzanso mawonekedwe a khungu la shaki, lomwe limagwiritsidwa ntchito kwambiri pokonzanso kukhuthala ndi mawonekedwe a pamwamba pa kutulutsidwa kwa pulasitiki.

LitiChithandizo Chothandizira Polima Chopanda Polima cha PFAS (PPA) SILIMER 5091Imaphatikizidwa mu metallocene polypropylene (mPP) matrix, imasintha kayendedwe ka mPP, imachepetsa kukangana pakati pa unyolo wa polima, komanso imaletsa kumamatira panthawi yokonza. Izi zimathandiza kukonza njira zotulutsira ndi kuumba, kuthandizira njira zopangira bwino komanso kuthandizira kuti zinthu ziyende bwino.
