Chiyembekezo cha Makampani a Americas Chemical mu 2019 | Melamine Powder Resin

Gawo la Msika Wamafuta Achilengedwe Amafuta Achilengedwe a 2019 Limakhudza Kusanthula Kwachigawo, Osewera Opambana, Mapulani Okulitsa, Zochitika Padziko Lonse, Zomwe Zapeza ndi Zopindulitsa mpaka 2025

7. Kupaka kumalowetsa mankhwala m'zakudya. Antimony ndi malata amagwiritsidwa ntchito popakira zinthu kuchokera komwe angalowetse chakudya. Zolemba, zitini, mapoto ndi zotengera zosungira zimakhala ndi mankhwala omwe amatha kutulutsidwa kuchokera ku chakudya chochepa. Akalowetsedwa, amayambitsa matenda osiyanasiyana.

Ngati mukupanga kusintha kwamapangidwe monga gawo la chipinda chanu chosinthira, tengani mwayi wowonjezera mashelufu anzeru okhazikika. Mmisiri wa matabwa kapena mmisiri wa matabwa atha kutengera izi pomanga makoma a zipupa. Mu master suite yayikulu, mutha kumanganso khoma lothandizira kukonza malo ndikuwonjezera kusungirako. 

Bollini, P., Brunelli, NA, Didas, SA & Jones, CW Dynamics ya CO2 adsorption pa amine adsorbents. 2. Kuzindikira za kapangidwe ka adsorbent. Ndi. Eng. Chemu. Res. 51, 15153–15162 (2012).

Kapena, zikomo kwa Choo-Choo, mudzi wawung'ono. Titamutsegulira, tinanyamula nkhumba yonse yolemera mapaundi 60, briskets ziwiri (zapadera za Jeff woyandikana naye ku Texan), bakha, nsomba za bluefish, ndi—bwanji?—biringanya. Ndinaitana aliyense amene ndimamudziwa mpaka Facebook atandidula, ndikuwapempha kuti abweretse zakumwa ndi mbali zomwe zingafanane ndi nyama (ndikundipatsa kupuma). Zotsatira zake zinali zodabwitsa: abwenzi ndi alendo akusefukira m'mphepete mwa msewu, chozizirira chodzaza ndi vinyo ndi mowa, komanso fungo la utsi wothirira m'kamwa lodzaza ndi njerwa iliyonse ndi mwala wa bulauni wapafupi. Kupyolera mu zonsezi, ndinali womasuka modabwitsa - zonsezo zinali pansi pa ulamuliro, ndipo ndinali ndi ngongole, makamaka, kwa Choo-Choo. Angakhale wamalonda pamtengo wowirikiza. —Matt Gross

Makapuwo anadzazidwa ndi madzi otentha, pang'ono acidic (monga khofi) ndipo anasiya kwa maola awiri. Izi zidabwerezedwa kasanu ndi kawiri pa chikho. Pambuyo pa kudzazidwa kwachitatu ndi kwachisanu ndi chiwiri, madzi mu kapu iliyonse amayesedwa ngati mankhwala. 

Zitsanzo zitatu za N-doped graphene (Sample 1 mpaka 3) zokhala ndi nayitrogeni zosiyanasiyana zidapangidwa ndi SHS patent method50. Chiwembu chithunzi cha zimene chipangizo chikusonyezedwa mkuyu. 1. Mu mmene kukonzekera ndondomeko Chitsanzo 1, 8 magalamu a carbamide (30 magalamu chitsanzo 2 ndi 21 magalamu chitsanzo 3) anawonjezedwa kwa osakaniza ufa wa 14,4 g wa magnesium. ndi 33.3 g wa kashiamu carbonate kenako mphero mu matope kwa mphindi 20. Zomwezo zinapitirira mu crucible yomwe inayikidwa mu chidebe chachitsulo cha 21.2 L pansi pa mpweya wa carbon dioxide pamtunda wa mlengalenga, monga momwe tawonetsera mkuyu. mphamvu gwero ndi kukana ofotokoza waya chotenthetsera ntchito poyatsira panopa 22 A. Zimenezo mowiriza zimafalitsidwa mwa osakaniza mu crucible kuchokera mozondoka mpaka pansi mu mtundu wa kuyaka yoweyula ndi kutha pamene kuyaka yoweyula anafika pansi. Chinthu chakuda chakuda chinatsukidwa ndi dilute hydrochloric acid (10 v / v %) ndikugwedezeka kwa maola awiri kuchotsa MgO, CaO ndi Mg zitsulo zotsalira. Mankhwalawa adasefedwa, kutsukidwa ndi madzi osungunuka ndi ethanol yamtheradi. Mapepala owonda kwambiri omwe adapangidwawo adasiyanitsidwanso pogwiritsa ntchito centrifuge pa 1000 rpm kwa mphindi 30 ndikusefa champhamvu. Pomaliza, chitsanzocho chinawumitsidwa mu vacuum pa 120 ° C kwa maola 24. Poyerekeza, chitsanzo cha pristine graphene (Sample 0) chinakonzedwanso ndi SHS kuchokera ku 16 magalamu a magnesium ndi 33.3 magalamu a calcium carbonate, yomwe inachokera pa chiwerengero cha stoichiometric cha zomwe zimachitika: 2 Mg + CaCO3 = 2 MgO + CaO + C; palibe carbamide yomwe idayambitsidwa momwemo ndipo mankhwalawa adathandizidwa ndi njira zomwe tafotokozazi.

Pansi: Zimatsuka modabwitsa. Poyesa ndidagwiritsa ntchito kuyeretsa ma countertops, matebulo, makoma, pansi, mbale zanga za agalu, mumazitchula. Pambuyo pakuyesa kwapakhomo ndidagwiritsa ntchito mu studio yojambulira anthu ambiri ndimathamangira kumbali.

Kuphatikiza apo, zitsulo zikuwonjezera kuwala kumitundu yolimba ngati safiro ndi ruby ​​​​ndi Epicurious cookware ndi colander.

Kumene ambiri mwa zithunzithunzi za melamine zomwe tidayesa zimakhala ndi zomera ndi zinyama zaku Britain, Kunyumba kwa Sainbury ndikolimbikitsa kwambiri ku Africa chifukwa cha zosonkhanitsa zapadziko lonse lapansi. Zodalirika zotsika mtengo koma zapamwamba, tinkakonda mtundu wamtundu wakuda, woyera ndi golide wosakanikirana ndi zithunzi za nyama. Ma mbale am'mbali ndi ma seva a crudités amapangidwa mopanda ungwiro kuti apereke mawonekedwe aluso, pomwe zoyikapo zimatha kufananizidwa ndi zinthu zopanda melamine mumtundu womwewo: yang'anani mbale ya mango, chiguduli cha pikiniki ndi chikwama chozizira.  

Kusankha kwathu maloko abwino kwambiri kumathandizira chitetezo chakunyumba kwanu, kuonetsetsa kuti alendo amalowa mosavuta, ndikukulepheretsani kutsekeredwanso kunja.

Akuti mazira abodza akuti ndi ochokera ku China, ali ndi zipolopolo zopangidwa ndi calcium carbonate, sera ya paraffin ndi gypsum powder, yolks ndi zoyera zopangidwa ndi alginate, alum, gelatin ndi coloring. Koma kodi mumadziwa kuti kuwopsa kwa mazira abodza sikwachilendo ku Malaysia? Zaka zitatu zapitazo, mayi wina wapakhomo ku Penang adadandaula ku Consumers Association of Penang. Nayi kanema wochokera ku The Star pomwe amafufuza mlanduwu:
