He aha te Polyethylene (PE)?
Ko te Polyethylene (PE), e mōhiotia ana ko te polythene, te polyethene rānei, tētahi o ngā kirihou e whakamahia whānuitia ana i te ao. He hanganga rārangi ngā polyethylene, ā, e mōhiotia ana ko ngā polymer tāpiri. Ko te whakamahinga matua o ēnei polymer hangai kei roto i ngā takai. He maha ngā wā ka whakamahia te Polyethelyne ki te hanga putea kirihou, pounamu, kiriata kirihou, ipu, me ngā geomembranes. E tika ana kia mōhiotia neke atu i te 100 miriona tāne o te polyethene e hangaia ana i ia tau mō ngā kaupapa arumoni me ngā kaupapa ahumahi. -
He tātaritanga o te whakahaeretanga o te mākete kaweake PVC o tōku whenua i te haurua tuatahi o te tau 2022.
I te haurua tuatahi o te tau 2022, i piki ake te mākete kaweake PVC i ia tau. I te hauwhā tuatahi, i pāngia e te paheketanga ōhanga o te ao me te mate urutā, he maha ngā kamupene kaweake ā-rohe i tohu kua iti haere te tono mō ngā kōpae o waho. Heoi, mai i te tīmatanga o Mei, me te whakapai ake i te āhuatanga o te mate urutā me te raupapa o ngā mahi i whakatinanahia e te kāwanatanga Haina hei whakatenatena i te whakaoranga ōhanga, kua tino teitei te tere whakahaere o ngā umanga hanga PVC ā-rohe, kua mahana ake te mākete kaweake PVC, ā, kua piki ake te tono mō ngā kōpae o waho. E whakaatu ana te tau i tētahi ia tipu, ā, kua pai ake te mahi whānui o te mākete ki te wā o mua. -
He aha te whakamahinga o te PVC?
He maha ngā whakamahinga o te polyvinyl chloride (PVC, vinyl rānei) e whakamahia ana i roto i ngā mahi hanga whare, hauora, hikohiko, motuka me ētahi atu rāngai, mai i ngā paipa me ngā pakitara, ngā pēke toto me ngā ngongo, ki te whakamahana waea me te taura, ngā wāhanga pūnaha matapihi me te maha atu. -
Kua tata te tukunga atu o te kaupapa whakawhānui ethylene me te whakamahine miriona tana a Hainan Refinery.
Kei roto i te Rohe Whakawhanake Ōhanga o Yangpu te Kaupapa Whakapaipai me te Matū Ethylene o Hainan me te Kaupapa Whakahou me te Whakawhanui Whakapaipai, me te haumitanga katoa neke atu i te 28 piriona yuan. Tae noa ki tēnei wā, kua eke te ahunga whakamua o te hanganga katoa ki te 98%. I muri i te otinga o te kaupapa me te whakaurunga ki te mahi, e matapaetia ana ka neke atu i te 100 piriona yuan o ngā ahumahi o raro. Ka tū te Huihuinga Whakawhanuitanga Rauemi Olefin me te Huihuinga o raro Hiranga ki Sanya i te 27-28 o Hūrae. I raro i te āhuatanga hou, ka matapakihia te whanaketanga o ngā kaupapa nui pēnei i te PDH, me te pakaru o te ethane, te ia o ngā hangarau hou ā muri ake nei pēnei i te hinu mata tika ki ngā olefin, me te whakatupuranga hou o te waro/methanol ki ngā olefin. -
MIT: Ka hangaia e ngā matūriki iti o te polylactic-glycolic acid copolymer te kano kano "whakarei ake i a ia anō".
I roto i te puka hou, Science Advances, e ai ki ngā kaipūtaiao o te Massachusetts Institute of Technology (MIT), kei te whakawhanakehia e rātou he kano ārai mate kotahi-horopeta e whakapakari ana i a ia anō. I muri i te werohanga o te kano ārai mate ki roto i te tinana tangata, ka taea te tuku i ngā wā maha, me te kore e hiahiatia he werohanga whakapakari. E whakaarohia ana ka whakamahia te kano ārai mate hou ki ngā mate mai i te rewharewha ki te Covid-19. E ai ki ngā pūrongo, he matūriki poly(lactic-co-glycolic acid) (PLGA) tēnei kano ārai mate hou. He matūriki waro polymer mahi pirau te PLGA, kāore he paitini, ā, he pai te hototahi ki te koiora. Kua whakaaetia kia whakamahia ki ngā mea tāpiri, ki ngā tuitui, ki ngā rauemi whakatika, me ētahi atu. -
Kamupene Matū Yuneng: Te whakaputanga ahumahi tuatahi o te polyethylene rehu!
Nō nā tata nei, i angitu te whakaputa a te wāhanga LLDPE o te Polyolefin Center o Yuneng Chemical Company i te DFDA-7042S, he hua polyethylene rehu. E mārama ana ko te hua polyethylene rehu he hua i ahu mai i te whanaketanga tere o te hangarau tukatuka o raro. Ko te rauemi polyethylene motuhake me te mahi rehu i runga i te mata e whakaoti ana i te raruraru o te mahi tae ngoikore o te polyethylene, ā, he kanapa teitei. Ka taea te whakamahi i te hua i roto i ngā mara whakapaipai me te tiaki, he pai mō ngā hua tamariki, ngā roto waka, ngā rauemi tākai, tae atu ki ngā tāke rokiroki ahumahi me te ahuwhenua nui, ngā taonga takaro, ngā arai rori, me ētahi atu, ā, he tino nui te tirohanga mākete. -
Kei te tata te hokinga mai o te 1.65 miriona tana o te polyolefin a Petronas ki te mākete Āhia!
E ai ki ngā purongo hou, kua tīmata anō a Pengerang i Johor Bahru, Malaysia, i tana waeine polyethylene iti-kiato raina (LLDPE) 350,000-tana/tau i te 4 o Hūrae, engari tera pea ka roa te wā e tutuki ai te mahi pumau. Haunga tēnā, e matapaetia ana ka piki ake tana tipu polypropylene (PP) hangarau Spheripol 450,000 tana/tau, te tipu polyethylene (HDPE) teitei-kiato 400,000 tana/tau me te tipu polypropylene (PP) hangarau Spherizone 450,000 tana/tau mai i tēnei marama kia tīmata anō. E ai ki te aromatawai a Argus, ko te utu o te LLDPE i te Tonga-Rawhiti o Āhia me te kore taake i te 1 o Hūrae he US$1360-1380/tana CFR, ā, ko te utu mo te kukume waea PP i te Tonga-Rawhiti o Āhia i te 1 o Hūrae he US$1270-1300/tana CFR me te kore taake. -
Kua huri ngā hikareti ki ngā takai kirihou pirau-ora i Inia.
Nā te aukati a Īnia i te 19 kirihou whakamahi-kotahi kua puta he panoni i roto i tana umanga hikareti. I mua i te 1 o Hūrae, kua hurihia e ngā kaihanga hikareti Īnia ā rātou takai kirihou tuku iho o mua ki ngā takai kirihou pirau-koiora. E kī ana te Tobacco Institute of India (TII) kua hurihia ā rātou mema, ā, kua tutuki ngā kirihou pirau-koiora e whakamahia ana i ngā paerewa o te ao, me te paerewa BIS i tukuna tata nei. E kī ana hoki rātou ka tīmata te pirau-koiora o ngā kirihou pirau-koiora i te pa atu ki te oneone, ā, ka pirau-koiora noa i roto i te whakawairakau me te kore e whakararu i ngā pūnaha kohikohinga para totoka me te hangarua. -
He Tātari Poto mō te Whakahaere o te Mākete Konupūmā Warowaihā ā-Rohe i te Hawhe Tuatahi o te Tau.
I te haurua tuatahi o te tau 2022, kāore te mākete konupūmā kāpōti ā-rohe i haere tonu i te ia o te piki me te heke o te tau 2021. I tata te mākete whānui ki te rārangi utu, ā, i pāngia e ngā piki me ngā heke me ngā whakarerekētanga nā te pānga o ngā rauemi mata, te tuku me te tono, me ngā āhuatanga o raro. I te haurua tuatahi o te tau, kāore he kaha whakawhānui hou o ngā tipu PVC tikanga konupūmā kāpōti ā-rohe, ā, he iti noa te pikinga o te tono mākete konupūmā kāpōti. He uaua ki ngā umanga chlor-alkali e hoko ana i te konupūmā kāpōti ki te pupuri i te kawenga pumau mō te wā roa. -
I puta he pahūtanga i roto i tētahi tauhohenga PVC o tētahi kamupene hinu nui i te Middle East!
I pānuitia e te kamupene matū hinu nui o Turkey, a Petkim, i te ahiahi o te 19 o Hune, 2022, i puta he pahūtanga ki te tipu Aliaga. I puta te aituā i roto i te tauhohenga PVC o te wheketere, kāore he tangata i whara, i tere te whakahaere i te ahi, engari tera pea ka mutu te mahi a te waeine PVC mō te wā poto nā te aituā. Tērā pea ka nui ake te pānga o tēnei kaupapa ki te mākete PVC o Ūropi. E ai ki ngā pūrongo, nā te mea he iti ake te utu o te PVC i Haina i tērā o ngā hua o roto o Turkey, ā, he teitei ake te utu o te PVC i Ūropi i tērā o Turkey, ko te nuinga o ngā hua PVC a Petkim kei te kaweakehia ki te mākete o Ūropi i tēnei wā. -

Te tāpiri i ngā muka waikawa polylactic ki ngā kākahu kura.
Kua mahi tahi a Fengyuan Bio-Fiber me Fujian Xintongxing ki te whakamahi i te muka waikawa polylactic ki ngā kakahu kura. Ko tōna mahi mimiti makuku me te werawera he 8 ngā wā i ngā muka polyester noa. He pai ake ngā āhuatanga patu huakita o te muka PLA i ngā muka kē atu. Ko te ātete miro o te muka ka eke ki te 95%, he pai ake i ngā muka matū kē atu. Hei tāpiri, ko te papanga i hangaia ki te muka waikawa polylactic he pai ki te kiri, ā, he ātete makuku, he mahana, he manawa hoki, ā, ka taea hoki te aukati i ngā huakita me ngā mite, ā, he ātete mura me te ahi. Ko ngā kākahu kura i hangaia ki tēnei papanga he pai ake ki te taiao, he haumaru ake, he whakamarie ake.
