Styrene: Pehea pilikia loa, a pehea?

Styrene-kapaia colorless kinowai waiwai me kekahi mau 'ʻala i hiki i ka hewa ana i kanaka ola. Currently phenylethylene, vinylbenzene a me ka'etolina e hoʻomano hoʻohana ma ka hanaʻano nui i loko o ka? Iecaianoaaiiie o polymers a me kemikala rubbers. O ka holo ana, e hana ana ka hana me kēia mau Nine Inch e malama ikaika malama kaiapuni.

? Iecaianoaaiiuo o styrene

E kiʻi i kēia mea i loko o kūikawā palapala koho (holomua hana ke hiki 150-300 tausani na tona o ka huahana no makahiki) ma dehydrogenation. Ke naoh, i kūpono synthesized styrene hoʻolaha like endothermic, a i wahi ma ka wela o ma kahi o 600-700 degere. Ua hoʻohana i ka hao'okesaside hōʻeleu me ka hou o ka chromium a me ka potasiuma. Ke kūpono neoneo ua malamaia lakou nei, e ka nunui-ke kahua kahua. Inā e kue ana i ka hana 'ole? Iecaianoaaiiie o ka' enehana hiki i hoʻomaka ai styrene hoʻomehana honua i loko o ke kaiapuni. About mea ia IeAUPIIe, IAa IO ka hopena, kamakamailio ae la oia i ka apana uuku na kumuwai. Mua, e wehewehe mai i ka mea i keia waiwai mea a ka ano ka mea, oko a.

waiwai

No laila, i ke ano o ka Nine Inch - styrene? Kona waiwai i nui loa. E ka noonoo ia:

• ilihune loa solubility i loko o ka wai;
• Light'okesaside;
• makaukau solubility i loko o ke aloha i huiʻia;
• ka hiki e hooholo koke hoike mai i ka polymers;
• polymerization e hana i ka paa vitrified nui;
• copolymerization me na monomers;
• ka piʻiʻana halogens.

Kikokiko i ka kanaka kino styrene, He loa kaʻawaʻawa loa ala a nei nā ma ka luna Hawaiian Airlines, a ma digestive'āpana. Ma ka hui 'ana me ka fluids i loaʻa ka mea, e hiki e ke kemu ma ka ili.

Styrene a me nā hana

Kēia waiwai He nō nā palapala, a hiki i ka hopena maikaʻi ma luna o ola meaola. Naʻe, i ka styrene i loko o ka lewa hikiwawe loa decomposes. Nolaila, a hiki ina accidental hookuu aku oia i ka nui o ka hewa ano, ka mea hiki ole pili. I ka aina a me ka groundwater styrene decomposes i loko o kona constituent waiwai. Ka mea hana i loko o ka lewa, a ma lalo o ka aoao o ke Map.

Eia naʻe, i loko o ka hapanui Hawaii ka i kā mākou helu o ka waiwai kinoea i loko o ka puni 'ia o ka hana, na na ma ke kānāwai.

Na rula no ka hana me ka styrene

Ma ka? Iecaianoaaiiie o keia waiwai, a me kona hoʻohana no ka hana ana o polymers, o ka papa, e mālama maluhia. Ma ka hapanui'āina o ko ke ao nei i ka i kā mākou allowable lehulehu o styrene i loko o na keena ma a limahana o ka poe i noho ai. Malalo o na rula o ia nā hālāwai hoʻonaʻauao ka mea, ua pono e iai? Oaiaaou efficient hoʻokomo ea nenoai. O na papa, na limahana o kēia mau hana e e ao mai i ka Inhale i ka ohu styrenics, a hoʻohana pilikino aiiay lako a inā pono.

Malama maluhia, hoʻohuihui me nā waiwai (catalysts, peroxides, mea hoʻonui) styrene. Reactions mālama 'ia me ka'ōlelo aʻo, e hiki i ke kau loa hoʻomaka koke' ole he undesired 'ano paha i loko. Transfusion styrenes a me ka paʻipaʻiʻia ai e halihaliia oia iwaho i kaawale wahi maikai loa 'ia ua hōʻike hewa no keia mea, a ventilated pono.

Polymerization o styrene ia lŘlŘ a hiki i mehana ea. Ka pilikia o kēia kaʻina mea i ka mea hiki ke 'ai pono i loko o ka Naita. Nolaila, o ka waiwai e waiho waho i kulike ai me na olelo.

Hoʻokaʻaʻike me keia Nine Inch hiki i kekahi kanaka e like me ka huʻi kaʻapu kōheoheo naoh a me ka maʻi maʻi. ʻaneʻane a pau nā loko - puupaa, akepaa, urinary, koko nenoaiu - hiki ke loli ma na hui o ka waiwai e like me styrene. Pehea pilikia o keia carcinogen no kānaka ua hōʻike hewa i loko o kēlā i kēia mau hihia i loko o au mamuli a kūkā mai ma lalo nei. Styrene ua noonoo make systemic kaʻawahia, a pili i 2 papa o ka p ÷ ino. Ona i kānaka hiki ka hopena i inhalation o ka lewa i loaʻa ka 10 000 mg / m + ³ o ka styrene.

He aha hiki i huʻi loa styrene

A hiki i ka lehulehu o ka mahu i loko o ka lewa i loko o ka nui o ka 420 mg / ^m3 i kānaka hoʻomaka e hōʻike i nā hōʻailona o ka hookaawale ana o ka mucous membranes o ka naehana'āpana, a me nā maka. A hiki i ka maʻiʻo aku i 840 mg / m + ^3? Ac? Nausea a me ka drowsiness. Ma keia hihia, no ka luahi me nā'ēheu kēia'ēheu o nā pilikia a me ka vestibular i hoʻomākaukauʻia.

No laila, ua ua hookolokolo aku la ia i ka nui o ka poino hiki e pili ana i ke kanaka kino styrene. Pehea pilikia loa keia Nine Inch huahana, oe e ike. O ka hana ana, i loko o ia mau wahi, kahi malaila he lōʻihi manawa e kanaka, i ka lehulehu o ka waiwai ma ka ohu pono i oi aku mamua o ka mea i kā mākou ana palena. Ma na hana o ko lākou hana 'ole? Iecaianoaaiiuo o polymers a me rubbers, ka mea e e hookomoia ma ka lewa i loko o ka nui o ole aku ma mua o:

Styrene ma ka meaʻai'ōpala

Eia naʻe, i kēia waiwai e komo i ke kanaka kino,ʻaʻole wale nō ka wā o ka papa no ka mea kanu hoʻomehana honua. Polystyrene a me acrylonitrile-butadiene-styrene, e hoʻomano hoʻohana i ke kala'ōpala i ke amo a me ka waiho waho pūnaewele o nå mea 'ai. Ua makemake mea i ka mea, e noho malie hoi e loa. Naʻe, ka noiʻi loaʻa ia styrene lātoma mea hiki ke neʻe i loko o ka ai, mai nā ka pahee a me ka ikaika, mai ka'ōpala. Ma kekahi hihia, a he waiwai haawi mai i ka ai, ka waiu a me ka wai, i kaʻawaʻawa loaʻaiʻana.

Pili styrene, i ka loa kaʻawaʻawa loa ala, a ma ka? Iecaianoaaiiie o ka hale 'ikamu, kūkuluʻia nā puke a no laila, ma luna o. D.

poho i ka Styrofoam

Kēia mea mea a ianoiyuaa a kekahi o ka loa hanohanoʻano o ka'īpale. Oe ke kuai ia i loko o kekahi lako e kūʻai, a me ka mea, ua hoʻohana 'ia loa kaiāulu, a me ma ka hana o ka hale noho hale. Manawa polystyrene undergoes hoʻololi iho oluolu decompose ka a pau ke ola au e 10-15% ma. A pau keia lātoma maʻiʻo o ka decomposition huahana mea ma ka liʻiliʻi 65%.

Eia hou, ma ka? Iecaianoaaiiie o keia iaia? Aaaoaeuiuo polymerization o ka styrene mea kākaʻikahi loa a me kaʻaʻahu. Kēia 'o ia hoʻi i loko o nā pellets mea mau he koena dala o ia mea. Nolaila, copolymers o styrene, ma kekahi hihia hoʻokuʻu akula noxious fumes. Ka nui, e hoike ana i ka hoʻohana 'ana i ka insulator no'īpale o ka noho Hoʻonaʻauao' ia kēia i loko o ka rula, Eia naʻe, ua ike mamao ole a pau. Ma keia hihia ka mea, e aho nō ke hoʻohana 'ē aʻe mea. Eia naʻe, e makaala, a me ka ua iloko o ia styrene i ka me i loko o ka hua. Mai ka waiwai ua manaoia e e oi nā palapala ma mua o formaldehyde, mea no maikaʻi e insulate i ka hale, mai ka loko me ka mea pōhaku hulu hipa.

vinyl Wallpaper

I kekahi manawa, na mea nona o n iaainoaoeii neo mea i ike e pili ana i ka mea i ka hoopau ana i ke mea i hoʻohana no ka kapili, he styrene. Pehea pilikia loa keia Nine Inch huahana no kānaka, ua i mua i loaʻa. No laila, e pili ana i lehulehu mea a me ko ka hale ona 'ikamu i e ike, e ike maopopo leʻa aho la ia. No ka laʻana, he uuku nui o ka waiwai maloko o ka vinyl Wallpaper. Eia naʻe, e like Styrofoam, i kēia 'ano o ka hoʻopau i nā pā i loko o ka noho ele ele hiki ke hoʻohana. Ma lalo ano o na kumu o ka styrene Wallpaper ua ole anao? Aou. I ka lumi pepa keu me ka vinylʻikeʻia ma ka ohu, pono e hoonui i ka Ambient mahana mea ole e emi malalo o 50 kekelē Kelekia.

ABS-Ka lula ea Ke

ABS i ka hopena hoʻopale kēpau hoʻohana no ka hana ana i kaʻa māhele (manual nokia kumu hoʻohālikelike a, dashboards, a pela aku .. D.), neo? Aaiiai? O ka hale nā mīkini home (holo cleaners, loihi ka pāʻana o, kope) a me ka uilaʻoe (CPU, nā kahu nānā), lako, palama, 'inikua lako , suitcases a me na kamalii ka toys.

Ma ka maʻamau moku'āina o kekahi mau pilikia no kanaka ola, a pau keia mau mea e 'ike'. Styrene maemae Ka hoʻomaka 'ana e hookaawale mai ia wale nō ma lalo o ke ana ma lalo nei:

• A nui loa ikaika paio hahana maoli nō.
• I lapaau wā hoʻohana me ka biomaterial.
• I ana mau lula no ka ai pūnaewele. Pakahi aku la ia unacceptable ninini ana i ipu o ia mau mea ka waiʻona. Ma keia hihia i ka hookoia mea like i ka paio hahana maoli nō.

Currently, me ka like ana o ka styrenic polymers me ABS, a pau huakūʻai a me ka 'enekinia, Ka lula ea Ke mea 50%.

He aha e hana ma ka hihia o kaʻapu kōheoheo styrene

Ma ia hihia, ina paku ole ia i ke kiekie nā hoʻohui like o ka styrene fumes i ke kanaka no ka lōʻihi manawa, a ia i na hoailona o kaʻapu kōheoheo, oe e hana i kēia mau hana:

• Wehe i hoʻohuli ai i nā kanaka, mai ka ua hoʻohaumiaʻia pa e hoʻomaʻemaʻe ea.
• Inā unconscious ole loa ilihune ana, e hoʻohana i ka oxygen ea paha.
• Inā pono, e kaʻimi hoʻopunipuni hanu.
• Kanaka hoʻoponopono i ka wela o ka loli ana o ke kino. UaʻAʻole e mahuahua ai a ua hoʻemi.

I ka styrene ua ma luna o kaʻili a me mucous membranes pono nui holoi me ka wai. Lapaʻau manawa e ole e emi malalo o 15 minuke. Ma hope o kona hana ana i ka luahi ua koi 'ia e ia i ka haukapila. Inā styrene koke loaʻa i loko o ke kino, ka mea pono mea mua o nā mea a pau e inu nui loa dala o ka waiu wai paha. Mahope iho o keia, me ka hoʻomanawanui pono e koke hospitalized.

E like me 'oe ke ike, i ke? Iecaianoaaiiie o styrene - he kaʻina hana i, ina ole maluhia rula no ka poe hana mea,ʻaʻole e noho malie hoi. Nolaila, e hali ana mai? Iecaianoaaiiuo hana i ka hana e e like manao a me ka makaala lakou. E e makaʻala ka wā kūʻai i kēia hale lako a me ka ai i loko o polystyrene pahu.
