Chiyembekezo Chachitukuko cha Hydrogenated Bisphenol A (HBPA)

Hydrogenated Bisphenol A(HBPA) ndi chinthu chatsopano cha utomoni wofunikira pamakampani opanga mankhwala abwino. Amapangidwa kuchokera ku Bisphenol A(BPA) ndi hydrogenation. Kugwiritsa ntchito kwawo kuli kofanana. Bisphenol A amagwiritsidwa ntchito makamaka popanga polycarbonate, epoxy resin ndi zinthu zina za polima. Padziko lonse lapansi, Polycarbonate ndiye gawo lalikulu kwambiri la BPA. Ali ku China, pakufunika kwambiri mankhwala ake otsika, epoxy resin. Komabe, pakuwonjezeka kwachangu kwa mphamvu yopanga polycarbonate, kufunikira kwa China kwa BPA kukukulirakulira, ndipo momwe amagwiritsidwira ntchito pang'onopang'ono amalumikizana ndi dziko lapansi.

Pakadali pano, China ikutsogola pakukula kwazakudya ndikugwiritsa ntchito makampani a BPA. Kuyambira 2014, kufunikira kwapakhomo kwa BPA nthawi zambiri kwakhala kukukulirakulira. Mu 2018, idafikira matani 51.6675 miliyoni, ndipo mu 2019, idafika matani 11.9511 miliyoni, ndikuwonjezeka kwa chaka ndi 17.01%. Mu 2020, zotulutsa zapakhomo zaku China za BPA zinali matani 1.4173 miliyoni, voliyumu yotumizira munthawi yomweyo inali matani 595000, voliyumu yotumiza kunja inali matani 13000, ndipo kufunikira kwa China kwa BPA kunali matani 1.9993 miliyoni. Komabe, chifukwa cha zotchinga zapamwamba zaukadaulo pakupanga kwa HBPA, msika wapakhomo wakhala ukudalira zinthu zochokera ku Japan ndipo sunapangebe msika wotukuka. Mu 2019, chiwerengero chonse cha China chofuna HBPA ndi pafupifupi matani 840, ndipo mu 2020, ndi pafupifupi matani 975.

Poyerekeza ndi zinthu zopangidwa ndi utomoni wopangidwa ndi BPA, utomoni wopangidwa ndi HBPA uli ndi zabwino izi: kusakhala kawopsedwe, kukhazikika kwamankhwala, kukana kwa UV, kukhazikika kwamafuta komanso kukana kwanyengo. Pokhapokha kuti katundu wakuthupi wa mankhwala ochiritsidwa ndi ofanana, kukana kwa nyengo kumawonjezeka kwambiri. Choncho, HBPA epoxy resin, monga nyengo kugonjetsedwa epoxy utomoni, makamaka ntchito mapeto apamwamba kupanga ndi ntchito minda, monga apamwamba mtengo ma CD ma CD, apamwamba zipangizo magetsi kutchinjiriza, ❖ kuyanika tsamba zimakupiza, zida zachipatala zigawo zikuluzikulu, composites ndi minda ina.

Pakadali pano, kupezeka ndi kufunikira kwa msika wapadziko lonse wa HBPA kumakhala koyenera, komabe pali kusiyana pamsika wapakhomo. Mu 2016, zofuna zapakhomo zinali pafupifupi matani 349, ndipo zotuluka zinali matani 62 okha. M'tsogolomu, ndikukula kwapang'onopang'ono kwa sikelo yoyendetsera ntchito, HBPA yapakhomo ili ndi chiyembekezo chokulirapo. Kufunika kwakukulu kwa msika wa BPA kumapereka malo ochulukirapo azinthu za HBPA pamsika wapamwamba kwambiri. Ndi kukweza mosalekeza kwa makampani a utomoni wapadziko lonse lapansi, kutukuka kwachangu kwa zida zatsopano komanso kusintha kwapang'onopang'ono kwa zomwe ogula amafunikira pamtundu wazinthu ndi magwiridwe antchito, mawonekedwe abwino kwambiri a HBPA adzalowanso m'malo mwa gawo lamsika wapamwamba wa BPA ndi kulimbikitsanso kupanga utomoni waku China komanso kugwiritsa ntchito kunsi kwa mtsinje.
