Umbiko Wocwaningo Ngemakethe Yempuphu ye-Melamine | I-Melamine Powder Resin

Umbiko Wokucwaninga Ngemakethe Yempuphu Ye-Melamine Yokukhula Okungenzeka, Ukwabelana, Isidingo kanye Nokuhlaziywa Kwabadlali Ababalulekile - Izibikezelo Zocwaningo kuya ku-(2018 - 2026). Umbiko wocwaningo lweMakethe ye-Melamine Powder yomhlaba wonke uhlanganisa izici ezibalulekile ezibhekele ukuthuthukiswa kweMakethe Yempuphu ye-Melamine yomhlaba wonke.

Uma inhloso ye-melamine kuwukusikhohlisa ukuthi sicabange ukuthi sidla izinto eziphukayo zangempela le sethi elungele ipikiniki, eyenziwe ukulingisa i-rustic glazed terracotta, iwumpetha wokuzifihla. Yengeza ukuthinta okungavamile kumaragi wethu wepikiniki, i-tableware inephethini ekhanyayo nenemibala yamaMoor futhi yakhelwe ukwabelana. Ipheya lezitsha zokucwilisa kanye nepuleti le-oval appetizer, kanye nesitsha sesaladi esikhulu esinamaseva ayindilinga akhangayo, kunikeza ukubukeka kweMedithera okunethezekile.

Inqolobane yethu yedatha ibuyekezwa ngokuqhubekayo futhi ibuyekezwe ithimba lochwepheshe bocwaningo, ukuze ihlale ibonisa amathrendi nolwazi lwakamuva. Ngekhono elibanzi lokucwaninga nokuhlaziya, I-Transparency Market Research isebenzisa amasu aqinile ocwaningo oluyisisekelo nolwesibili ekuthuthukiseni amasethi edatha ahlukile nezinto zocwaningo zemibiko yebhizinisi.

Izinkomishi zikhangiswa ngokuthi zenziwa ngoqalo noma nge-bamboo fiber, kodwa abakhiqizi bavame ukuhluleka ukusho ukuthi imicu igaywa ibe yimpushana bese inamathiselwa ibe yisimo senkomishi. Ngokuphawulekayo, zonke ziqukethe i-melamine resin, uhlobo lweglue eyenziwe nge-formaldehyde kanye ne-organic compound melamine.

Okuzokumangaza nakakhulu ukuthi eziningi zalezi zinto zivunyelwe yiziphathimandla zezokuphepha kokudla, kodwa zingaphansi kwemingcele. Ezinye izinto, njengobuthi obuthile, bukhona ngokwemvelo ekudleni. Ngakho-ke, ngisho noma iziphathimandla zokudla zazifuna, azikwazanga ukukuvimba ngokuphelele.

Ixhunywe le miphumela nokuziphatha kukazibuthe wamasampula, kunengqondo ukuphetha ngokuthi iziqongo ku-625 K zamasampuli e-N-doped graphene zidalwe ukubola kwamaqembu e-N, ngokulahleka kwamaqembu angama-N angumthombo we umzuzu kazibuthe, i-magnetization yehla ngokushesha. Ngakho-ke inani eliphakeme elingu-625 K liwumphumela wokungazinzi kokushisa kwe-N-doped graphene phakathi kuka-600 no-650 K.

Umbiko weGlobal Thermosetting Resin Molding Materials for Electronics market uqala ngesifinyezo esiphezulu kanye nokwethulwa kwemakethe, okunikeza umbono ophelele wemakethe. Lesi sigaba sihlanganisa indawo yokubuka yeMakethe, ukuhlaziywa kochungechunge lwenani kanye nokuhlaziywa komthelela wezici zesibikezelo ezihlobene Nezinto Zokubumba I-Thermosetting Resin Zemakethe Yezogesi. Ukwengeza, umbiko we-Thermosetting Resin Molding Materials for Electronics uhlinzeka ngolwazi olubalulekile mayelana nezindleko zokukhiqiza, ukuhlaziya okuqhathanisayo phakathi kwe-quartz yokuhlanzeka okuphezulu nezinye izinto ezisetshenziswayo ezisetshenziswa kanye nokuhlaziywa kochungechunge lwenani elinemininingwane Yezinto Zokubumba I-Thermosetting Resin Yemakethe Yezogesi. Isigaba esilandelayo sihlaziya imakethe yomhlaba wonke ye-Thermosetting Resin Molding Materials ye-Electronics ngesisekelo sezigaba zayo kanye nezibikezelo zesibikezelo sesikhathi sika-2018-2026. Ngokwesisekelo sokubunjwa, imakethe yomhlaba wonke ye-Thermosetting Resin Molding Materials ye-Electronics ihlukaniswe yaba;

Senze indlela engabizi kakhulu futhi enwebekayo yokulungiselela inoveli ye-3D exhumene ne-N-doped graphene nanoribbon network (N-GRW) yezakhiwo. Umphumela we-N-GRW unokuminyana okuphezulu kwe-electron-donating quaternary N evumelana ne-ORR nokuqukethwe okuphezulu kwamaqembu asebenzayo ahoxiswa ngama-electron (pyridinic N, C=O) akhanga i-OER. Ngaphezu kwalokho, okuqukethwe okuphezulu kwe-nitrogen doping kungashintsha ukusatshalaliswa kweshaji eringini yekhabhoni, okuholela ekwenyukeni kwamandla okubopha ama-C1 kanye nokuvinjwa kwe-carbon corrosion ngesikhathi se-OER. Lokhu, kanye nesakhiwo senethiwekhi esixhumene se-3D sendawo ethile ephezulu, umthamo omkhulu wembotshana, kanye nokusabalalisa usayizi wembotshana ofanele, kunikeza umphumela wokusebenzisana ukuze kudaleke imisebenzi ebabazekayo kanye nokuzinza kwayo kokubili i-ORR ne-OER, idlula ikhabhoni ebikiwe engenayo insimbi. ama-catalysts ngisho nama-transition-metal oxide bifunctional catalysts. Amabhethri e-zinc-air ene-electrode amabili, asekelwe ku-electrode yomoya ye-N-GRW engasebenzi kabili nezinhlangothi ezisebenzayo zesifunda esithile ze-ORR ne-OER, angashajwa ngokuzinzile futhi ashajwe ngaphezu kwemijikelezo engu-150 ngo-2 mA cm−2. Ngesikhathi sokushajwa, amabhethri abonise amandla kagesi e-open-circuit engu-1.46 V, umthamo othize ongu-873 mAh g−1, kanye nokuminyana kwamandla okuphezulu okungu-65 mW cm−2. Ngaphezu kwalokho, amabhethri e-zinc-air ashajwa kabusha angashajwa ngokushesha futhi akhishwe lapho eshajwa futhi ekhipha ukuminyana kwamanje okufika ku-20 mA cm−2 ngaphezu kwamahora angu-30 ngokuzinza okuhle kakhulu kokuhamba ngebhayisikili. Umsebenzi wethu ubonise i-electrocatalysis eminingi ezimele yokusabela okuhlukahlukene ngokwethula izifunda eziningi ze-dopant ngokusebenzisa i-heteroatom doping carbon nanostructures eyodwa, futhi ngokokuqala ngqa, sathola amasayithi ahlukahlukene angenayo insimbi ahlobene nezinhlobo ze-N ezihlukene ku-N mono-doped carbon nanomaterials. Lokhu, kanye nomsebenzi we-electrocatalytic ongakaze ubonwe we-ORR-OER kanye nokusebenza kwebhethri okuqashelwe amacatalyst ethu asanda kuthuthukiswa e-N-GRW angenayo insimbi, kufanele kube nemithelela ebalulekile ekuthuthukisweni kwendlela yokwenziwa engabizi kakhulu, eyingozi yokukhiqiza i-carbon entsha ehlukahlukene. ama-catalyst angenazo insimbi ezinhlobonhlobo ezinkulu ze-electrochemical kanye ne-catalytic application.
