No ka hoʻomaopopo ʻana i ke kūlana maikaʻi o nā koʻi silicone a me nā ʻāpana silicone i kūʻai ʻia ma ka mākeke ʻo Qingdao a hāʻawi i nā mea kūʻai aku i ka ʻike huahana ʻoiaʻiʻo a hilinaʻi hoʻi, ua hoʻokumu ʻia ka Qingdao Municipal Consumer Protection Commission i nā hoʻokolohua hoʻohālikelike o kekahi mau ʻōpala silicone a me nā huahana mold silicone i ka hopena o ka makahiki. 2021. Ma ke kakahiaka o Malaki 9 ma ka hola 10, ua hoʻokumu ʻia kahi papahana hoʻolaha ʻepekema nui "Consumer Laboratory" i hana pū ʻia e ka Qingdao Municipal Consumer Protection Commission, Qingdao Municipal Quality Inspection Institute, a me Peninsula Urban Daily i hoʻokumu i ka "3.15 Special.

ʻO ka huina o nā laʻana no kēia hoʻokolohua hoʻohālikelike he 20 mau pūʻulu, ua kūʻai maoli ʻia ia mau mea āpau e nā limahana o ka Qingdao Consumer Protection Commission ma ke ʻano he mea kūʻai maʻamau i nā hale kūʻai kūʻai nui, nā hale kūʻai nui, a me nā kahua kūʻai e-commerce e like me JD a me Tmall ma Qingdao.Ma waena o lākou, he 10 mau pūʻulu o nā koʻi silicone mai nā hale kūʻai kūʻai waho;ʻO 10 mau pūʻulu silikoni, 7 pūʻulu mai nā hale kūʻai kūʻai pūnaewele, a me 3 mau pūʻulu mai nā hale kūʻai kūʻai pūnaewele.
Ua mālama ʻia ka hoʻokolohua hoʻāʻo ʻana ma ka Qingdao Product Quality Inspection and Research Institute, a ʻo nā mea hoʻāʻo e komo pū me ka hoʻohana ʻana i ka potassium permanganate, ka neʻe holoʻokoʻa, nā metala kaumaha (i ka Pb), ka neʻe ʻana o ka plasticizer (DEHP, DAP, DINP, DBP), a me nā mea hiki ke hoʻololi ʻia. antimony Sb, arsenic As, barium Ba, cadmium Cd, chromium Cr, lead Pb, mercury Hg, selenium Se).Aia i loko o nā kūlana ko GB 4806.11-2016 "National Food Safety Standard for Rubber Materials and Products in Contact with Food", GB 9685-2016 "National Food Safety Standard for the Use of Additives in Contact with Food Materials and Products", GB 31604.30-2016 "National Food Safety Standard for the Determination and Migration of Phthalates in Contact with Food Materials and Products" GB 6675.4-2014 "Safety of Toys - Part 4: Migration of Specific Elements", etc.
Ma kēia pukana o "Consumer Lab", e nānā pono mākou i ka neʻe ʻana o nā mea kīhini silicone i ka wā kuke, e hōʻike ana i kona ʻano kumu, he mea ʻike maikaʻi loa ia a me ka hanu.I ka pane ʻana i nā mea ʻino e like me nā metala kaumaha a me nā plasticizers e hopohopo nui nei i nā kamaʻāina a me nā mea kūʻai aku, ua hoʻonui nui ka hoʻokolohua i nā hoʻokolohua kūpono a hoʻohana i nā mea hana kiʻekiʻe a me nā mea hana no ke ana i kuhikuhi ʻia a pololei, me ka hoʻohana ʻana i ka ʻepekema e hoʻihoʻi i ka ʻoiaʻiʻo.
ʻO Han Bing, ke poʻo o ka papahana hoʻokolohua hoʻohālikelike o ka Qingdao Municipal Consumer Protection Commission, a me Sun Chunpeng, he ʻenekinia mai ka Qingdao Municipal Quality Inspection Institute, kipa i ka lumi hoʻolaha ola o ka "Consumer Laboratory" e hoʻokuʻu i nā hopena hope loa o ka hoʻokolohua a hāʻawi i ke alakaʻi alakaʻi mana.Pono e hoʻomaopopo ʻia ʻo nā hopena o kēia hoʻohālikelike hoʻohālikelike wale nō ke kuleana no nā laʻana a ʻaʻole hōʻike i ka maikaʻi o nā hiʻohiʻona ʻē aʻe a i ʻole nā hui o ka brand.ʻAʻole ʻae ʻia ka hui e hoʻohana i nā hopena hōʻike hoʻohālikelike no ka hoʻolaha ʻana me ka ʻole o ka ʻae ʻia;'O ke kumu kū'ai 'o ka hāpana wale nō ke kumu kū'ai i ia manawa.
I loko o ke keʻena kino a me ka kemika o Qingdao Quality Inspection Institute, ua hoʻouna mua ʻia nā ʻāpana 20 o nā huahana silicone i ka umu 220 degere a ʻelemakule i ka ea wela no 10 mau hola, e hoʻohālikelike ana i ke kaiapuni kiʻekiʻe o nā huahana silicone i ka hoʻohana ʻana i kēlā me kēia lā.Ma hope o 10 mau hola, e lawe i 20 mau laʻana a hoʻoluʻu iā lākou.E ʻoki i kahi ʻāpana o ka silica gel mai kēlā me kēia o nā laʻana he 20 e like me kahi lākiō hoʻokolohua no ka hoʻomākaukau ʻana.
Hoʻāʻo ʻia ka laʻana i ka ea wela ma 220 ° C no 10 mau hola
I ka hoʻohana ʻana i nā spatula silicone a me nā mold, ʻo ka hopohopo nui loa i nā kamaʻāina inā e neʻe kekahi mea.Hiki i ka papahana ho'āʻo o ka 'holo holoʻokoʻa' ke hopu pololei i ka nui o nā mea hoʻololi ʻole i loko o nā mea pili meaʻai e neʻe i loko o ka meaʻai.
Ua ʻike au i nā ʻenehana keʻena hana e hoʻoinu ana i ke silikoni i ʻoki ʻia i loko o kahi simulant meaʻai o 4% acetic acid a me 50% ethanol, e hoʻoluʻu iā ia no 4 mau hola ma 100 ℃, a laila e waiho i ka wai hoʻonā i loko o kahi kīʻaha evaporating a hiki i ka maloʻo.I kēia manawa, ua hoʻomaʻemaʻe maikaʻi ʻia kekahi o ka lalo o ka ipu e hoʻoheheʻe ʻia, me ke kīnā ʻole;Hiki keʻikeʻia kekahi me ka maka'ōlohelohe me kahi liʻiliʻi o ke koena keʻokeʻo i hoʻopaʻaʻia, e like me ka "scale".
