ʻO ka ʻoihana kemika ʻAmelika Hui Pū ʻIa no 2019 | Melamine Pauda Resin

ʻO ka 2019 Natural Fatty Acids Market Segmentation e uhi ana i ka loiloi kūloko, nā mea pāʻani kiʻekiʻe, nā hoʻolālā hoʻonui, nā ʻano o ka honua, nā loaʻa kālā a me ka wānana waiwai a hiki i 2025

7. Hoʻokomo ka Packaging i nā kemika i loko o ka meaʻai. Hoʻohana ʻia ka Antimony a me ka tin i nā mea hoʻopili mai kahi e hiki ai ke komo i ka meaʻai. ʻO nā kīʻaha, nā kini, nā pā a me nā pahu mālama i loaʻa nā kinikona e hiki ke hoʻokuʻu ʻia mai ia mau mea i ka meaʻai ma nā pae haʻahaʻa. Ke ʻai ʻia, hoʻoulu lākou i nā pilikia olakino.

Inā ʻoe e hoʻololi i ka hoʻololi ʻana ma ke ʻano o ka hoʻololi ʻana o kou lumi moe, e lawe i ka manawa kūpono e hoʻohui i kekahi mau papa hoʻomaha akamai. Hiki i ke kamanā a mea kūkulu hale paha ke hoʻokomo i kēia mau mea i ke kūkulu ʻana i nā paia stud. I loko o kahi master suite nui, hiki iā ʻoe ke kūkulu i kahi pā stud e kōkua i ka ʻāpana o ka hakahaka a hoʻohui i ka waiho ʻana i ke kaʻina hana.

A i ʻole, mahalo iā Choo-Choo, kahi kauhale liʻiliʻi. I ko mākou hoʻolaʻa ʻana iā ia, ua hoʻouka mākou i kahi puaʻa holoʻokoʻa he 60 paona, ʻelua briskets (ʻo koʻu hoa noho Texan ʻo Jeff kūikawā), kahi ʻeke, kekahi iʻa uliuli, a—no ke aha?—he eggplant. Ua kono maoli au i nā mea a pau aʻu i ʻike ai a ʻoki ʻo Facebook iaʻu, a noi aku iā lākou e lawe mai i nā mea inu a me nā ʻaoʻao e ana i ka ʻiʻo (a e hoʻomaha iaʻu mai ka kuke ʻana). ʻO ka hopena he epic: nā hoaaloha a me nā malihini e kahe ana ma ke ala ala, kahi mea hoʻomaʻamaʻa i piha i ka waina a me ka pia, a me nā mea ʻala ʻala e hoʻohāinu ai i kēlā me kēia ʻāpana pōhaku a me nā pōhaku ʻeleʻele o ke kaiāulu. I loko o ia mau mea a pau, ua hoʻomaha maikaʻi wau - ua mālama wau i kēia mau mea a pau, a ʻaiʻē wau iā Choo-Choo. He mea kūʻai ʻo ia ma ka pālua o ke kumukūʻai. —Matt Gross

Hoʻopiha ʻia nā kīʻaha me kahi wai wela, ʻakika iki (e like me ke kofe) a waiho ʻia no ʻelua hola. Ua hana hou ʻia kēia kaʻina hana ʻehiku manawa i ke kīʻaha. Ma hope o ke kolu a me ka ʻehiku o ka hoʻopiha ʻana, ua hoʻāʻo ʻia ka wai o kēlā me kēia kīʻaha no nā kemika. 

ʻEkolu N-doped graphene laʻana (Laʻana 1 a hiki i 3) me nā ʻokoʻa ʻokoʻa o ka nitrogen i synthesized e ka SHS patent method50. Hōʻike ʻia ke kiʻikuhi Schematic o ka hāmeʻa pane ma Fig. 1. Ma kahi kaʻina hana hoʻomākaukau maʻamau no ka Laʻana 1, 8 grams o ka carbamide (30 grams no ka Laʻana 2 a me 21 grams no ka Laʻana 3) i hoʻohui ʻia i ka pauka hui ʻia o 14.4 g o ka magnesium a me 33.3 g o ka calcium carbonate a laila wili ʻia i loko o ka pahū no 20 mau minuke. Hoʻomaka ka hopena i loko o kahi kīʻaha i hoʻokomo ʻia i loko o kahi pahu kila 21.2 L ma lalo o ka lewa carbon dioxide ma ke kaomi lewa, e like me ka hōʻike ʻana ma ka Fig. kumu mana a me kahi mea hoʻoheheʻe uea kūʻē kūʻē e hoʻohana ana i kahi au o 22 A. Hoʻolaha ʻia ka hopena ma o ka hui ʻana i loko o ka crucible mai ka ʻaoʻao a i lalo i kahi ʻano o ka nalu puhi a hoʻopau ʻia i ka wā i hiki ai ka nalu kuni i lalo. A laila hoʻomaʻemaʻe ʻia kahi huahana maka ʻeleʻele e ka waika hydrochloric dilute (10 v/v%) a hoʻoulu ʻia no ʻelua hola e wehe i ka MgO, CaO a me ke koena Mg metala. A laila kānana ʻia ka huahana, holoi ʻia me ka wai deionized a me ka ethanol piha. Ua hoʻokaʻawale hou ʻia nā ʻāpana lahilahi o ka huahana me ka hoʻohana ʻana i ka centrifuge ma 1000 rpm no 30 mau minuke a me ka kānana ʻana i ka supernatant. ʻO ka hope, ua hoʻomaloʻo ʻia ka hāpana i loko o kahi ʻūhā ma 120 °C no 24 mau hola. E like me ka hoʻohālikelike ʻana, ua hoʻomākaukau ʻia kahi laʻana graphene pristine (Sample 0) e SHS mai 16 grams o ka magnesium a me 33.3 grams o ka calcium carbonate, i hoʻokumu ʻia ma ka ratio stoichiometric o ka pane: 2 Mg + CaCO3 = 2 MgO + CaO + C; ʻAʻole i hoʻokomo ʻia ka carbamide i ka hopena a ua mālama ʻia ka huahana me nā kaʻina like e like me ka mea i ʻōlelo ʻia ma luna.

Ke laina lalo: Hoʻomaʻemaʻe maikaʻi ia. I ka wā o ka hoʻāʻo ʻana, hoʻohana wau iā ia e hoʻomaʻemaʻe i nā countertops, nā papaʻaina, nā paia, nā papahele, nā kīʻaha meaʻai a kaʻu ʻīlio, kapa ʻoe. Ma hope o ka hoʻāʻo ʻana i ka home ua hoʻohana au iā ia i loko o ka hale kiʻi paʻi kiʻi nui a holo wau ma ka ʻaoʻao.

Eia kekahi, ke hoʻohui nei ka metallic i ka luster i nā kala paʻa e like me ka sapphire a me ka ruby ​​​​me nā mea kuke Epicurious a me nā colanders.

Ma kahi o ka hapa nui o ka melamine picnicware a mākou i hoʻāʻo ai i nā hiʻohiʻona o nā mea ulu a me nā holoholona Pelekane, ua lawe pololei ʻo Sainsbury's Home mai ʻApelika no kāna hōʻiliʻili honua. ʻO ke kumu kūʻai hilinaʻi a kiʻekiʻe naʻe, makemake mākou i ke ʻano tribal i ka ʻeleʻele, keʻokeʻo a me ke gula i hui pū ʻia me nā kiʻi holoholona. ʻO nā ʻaoʻao ʻaoʻao a me nā kikowaena crudité ʻaʻole i hemolele ke ʻano e hāʻawi i kahi hiʻohiʻona kiʻi, ʻoiai hiki ke hoʻohālikelike ʻia ka hoʻonohonoho me nā huahana non-melamine ma ke ʻano like: e nānā i ke kīʻaha lāʻau mango, ka pā pīniki a me ka ʻeke ʻeke.  

ʻO kā mākou koho ʻana i nā laka akamai maikaʻi loa e hoʻomaikaʻi i kou palekana home, e hōʻoia e hiki i nā malihini ke komo me ka maʻalahi, a pale iā ʻoe mai ka laka hou ʻana.

Ua ʻōlelo ʻia ʻo nā hua hoʻopunipuni i hōʻike ʻia mai Kina, he mau pūpū i hana ʻia me ka calcium carbonate, ka paraffin wax a me ka pauka gypsum, a me nā yolks a me nā keʻokeʻo i hana ʻia me ka alginate, alum, gelatin a me ka kala. Akā, ua ʻike anei ʻoukou ʻaʻole hou ka makaʻu hua hoʻopunipuni ma Malaysia? ʻEkolu makahiki i hala aku nei, ua hoʻopiʻi kekahi wahine hale ma Penang i ka Hui Kūʻai o Penang. Eia kekahi wikiō mai The Star i ko lākou hoʻokolokolo ʻana i ka hihia:
