Ko te "Metallocene" e pā ana ki ngā matū honohono konganuku waro i hangaia e ngā konganuku whakawhiti (pērā i te zirconium, te titanium, te hafnium, me ētahi atu) me te cyclopentadiene. Ko te polypropylene i hangaia me ngā whakakorikori metallocene e kiia ana ko te metallocene polypropylene (mPP).
He nui ake te rere o ngā hua polypropylene Metallocene (mPP), he nui ake te wera, he nui ake te ārai, he tino mārama, he iti ake te kakara, ā, he maha ngā whakamahinga pea i roto i ngā muka, te kiriata whakarewa, te whakakoi werohanga, te hanga wera, te hauora, me ētahi atu. He maha ngā mahi matua o te hanga polypropylene metallocene (mPP), tae atu ki te whakarite i ngā whakakoi, te whakapūhui, me te tukatuka muri.
1. Te Whakarite i te Whakakōkī:
Te Kōwhiringa o te Whakakōkī Metallocene: He mea nui te whiriwhiri i te whakakōkī metallocene hei whakatau i ngā āhuatanga o te mPP ka puta. Ko te tikanga, ko ēnei whakakōkī he konganuku whakawhiti, pērā i te zirconium, te titanium rānei, e piri ana i waenganui i ngā ligands cyclopentadienyl.
Tāpiritanga Cocatalyst: He maha ngā wā ka whakamahia ngā whakakorikori Metallocene me te cocatalyst, he matū kei roto i te konumohe. Ka whakahohehia e te cocatalyst te whakakorikori metallocene, ka taea ai e ia te tīmata i te tauhohenga polymerization.
2. Te whakapūhui:
Te Whakarite i te Rauemi Whakatakotoranga: Ko te propylene, te monomer mō te polypropylene, te mea e whakamahia ana hei rauemi matua. Ka purea te propylene hei tango i ngā poke ka taea te whakararuraru i te tukanga polymerization.
Tatūnga Tauhohenga: Ka tū te tauhohenga polymerization i roto i tētahi tauhohenga i raro i ngā āhuatanga e āta whakahaeretia ana. Kei roto i te tatūnga tauhohenga te whakakorikori metallocene, te cocatalyst, me ētahi atu tāpiringa e hiahiatia ana mō ngā āhuatanga polymer e hiahiatia ana.
Ngā Tikanga Whakapūhui: Ko ngā tikanga tauhohenga, pērā i te pāmahana, te pēhanga, me te wā noho, ka āta whakahaeretia kia mau ai te taumaha ngota me te hanganga pūhui e hiahiatia ana. Mā ngā whakakorikori Metallocene ka taea te whakahaere tika ake i ēnei tawhā ki te whakaritea ki ngā whakakorikori tuku iho.
3. Te Whakakotahitanga (Whiringa):
Te Whakaurunga o ngā Mono-Kotahi: I ētahi wā, ka taea te whakakotahi i te mPP me ētahi atu monomer hei whakarerekē i ōna āhuatanga. Ko ngā mono-kotahi noa ko te ethylene me ētahi atu alpha-olefin. Mā te whakaurunga o ngā mono-kotahi ka taea te whakarite i te polymer mō ngā tono motuhake.
4. Whakamutu me te Whakamate:
Whakamutu Tauhohenga: Kia oti te whakapūhui, ka whakamutua te tauhohenga. He maha ngā wā ka tutuki tēnei mā te whakauru i tētahi kaihoko whakamutu e tauhohe ana ki ngā pito o te mekameka pūhui hohe, ka aukati i te tipu haere tonu.
Te Whakamātao: Kātahi ka tere te whakamatao, te tineia rānei te pūhui hei ārai i ngā tauhohenga atu, hei whakapakeke hoki i te pūhui.
5. Te Whakaora i te Pūmua me te Tukatuka-Mua:
Te Wehenga Pūmua: Ka wehea te pūmua mai i te ranunga tauhohenga. Ka tangohia ngā monomera kāore i tauhohenga, ngā toenga whakakorikori, me ētahi atu hua taha mā roto i ngā tikanga wehewehe maha.
Ngā Hipanga Tukatuka-Mua: Tērā pea ka whai i ētahi atu taahiraa tukatuka mō te mPP, pērā i te extrusion, te compounding, me te pelletization, kia tutuki ai te āhua me ngā āhuatanga e hiahiatia ana. Mā ēnei taahiraa ka taea te whakauru i ngā tāpiringa pērā i ngā kaihoko paheke, ngā antioxidants, ngā kaiwhakaū, ngā kaihoko nucleating, ngā tae, me ētahi atu tāpiringa tukatuka.
Te Arotau i te mPP: He Ruku Hōhonu ki ngā Tūranga Matua o ngā Tāpiri Tukatuka
Ngā Kaihoko PahekeHe maha ngā wā ka tāpirihia ngā kaitapa paheke, pērā i ngā amides ngako mekameka roa, ki te mPP hei whakaiti i te waku i waenga i ngā mekameka polymer, hei ārai i te piri i te wā e tukatukahia ana. Ka āwhina tēnei ki te whakapai ake i ngā tukanga whakaputa me te whakapūtanga.
Ngā Whakarei Rere:Ka whakamahia ngā whakarei rere, ngā āwhina tukatuka rānei, pērā i ngā ware pi polyethylene, hei whakapai ake i te rere rewa o te mPP. Ka whakaitihia e ēnei tāpiringa te matotoru, ā, ka whakarei ake i te kaha o te polymer ki te whakakī i ngā poka pokepokea ai, ka pai ake te tukatuka.
Ngā ārai mate:
Ngā Kaiwhakaū: He mea nui ngā antioxidants hei tiaki i te mPP mai i te pirau i te wā e tukatukahia ana. Ko ngā phenols me ngā phosphites kua āraihia he mea whakaū e whakamahia whānuitia ana hei aukati i te hanganga o ngā rauropi kore utu, hei ārai i te pirau wera me te pirau waikura.
Ngā Kaihoko Whakapūngao:
Ka tāpirihia ngā matū whakatupu matū, pērā i te talc me ētahi atu matū kore-waro, hei whakatairanga i te hanganga o tētahi hanganga tioata pai ake i roto i te mPP. Ka whakarei ake ēnei tāpiri i ngā āhuatanga ā-pūkaha o te polymer, tae atu ki te pakari me te ātete ki te pānga.
Ngā Tae:
Ngā Tae me ngā Pūwero: He maha ngā wā ka whakauruhia ngā pūwero ki roto i te mPP hei whakatutuki i ngā tae motuhake i roto i te hua whakamutunga. Ka whiriwhiria ngā tae me ngā pūwero i runga i te tae e hiahiatia ana me ngā whakaritenga tono.
Ngā Kaiwhakarerekē Pānga:
Ngā Elastomers: I ngā tono e tino hira ana te ātete pānga, ka taea te tāpiri i ngā whakarerekētanga pānga pēnei i te rapa ethylene-propylene ki te mPP. Ka whakapai ake ēnei whakarerekētanga i te pakari o te polymer me te kore e whakararu i ētahi atu āhuatanga.
Ngā Kaiwhakaōrite:
Ngā Tārua Maleic Anhydride: Ka taea te whakamahi i ngā mea whakataurite hei whakapai ake i te hototahitanga i waenga i te mPP me ētahi atu pūmua, ngā tāpiringa rānei. Hei tauira, ka taea e ngā tārua maleic anhydride te whakarei ake i te piri i waenga i ngā wāhanga pūmua rerekē.
Ngā Ārai Paheke me ngā Ārai Ārai:
Ngā Ārai Paheke: Haunga te whakaiti i te waku, ka taea hoki e ngā ārai paheke te mahi hei ārai-aukati. Ka ārai ngā ārai-aukati i te piri o ngā mata kiriata, pepa rānei i te wā e rongoa ana.
(He mea nui kia mōhio ko ngā tāpiri tukatuka motuhake e whakamahia ana i roto i te hanganga mPP ka rerekē pea i runga i te tono e hiahiatia ana, ngā tikanga tukatuka, me ngā āhuatanga rauemi e hiahiatia ana. Ka āta whiriwhiria e ngā kaihanga ēnei tāpiri kia tutuki ai te mahi tino pai i roto i te hua whakamutunga. Mā te whakamahinga o ngā whakakorikori metallocene i roto i te hanga mPP ka whakaratohia he taumata whakahaere me te tika anō, e āhei ai te whakaurunga o ngā tāpiri i roto i te huarahi ka taea te whakarite kia tutuki ai ngā whakaritenga motuhake.)
