He aha nā halogens?
ʻO nā mea e like me ka fluorine, chlorine, bromine, iodine a me ka astate he halogens a ʻike ʻia i ka hiku o ka hui nui i ka papa manawa o nā mea.Loaʻa lākou i loko o nā pūhui kemika he nui, no ka laʻana ma ka polyvinylchloride.ʻO PVC, e like me ka mea i ʻike ʻia no ka pōkole, he lōʻihi loa ia, ʻo ia ke kumu i hoʻohana ʻia ai i nā huahana ʻenehana he nui, a me ka insulation a me nā mea sheath i nā kaula.Hoʻokomo pinepine ʻia ʻo Chlorine a me nā halogens ʻē aʻe i mea hoʻohui e hoʻomaikaʻi ai i ka pale ahi.Akā hiki mai kēlā me ke kumukūʻai.He pōʻino nā Halogen i ke olakino.No kēia kumu, hoʻohana nui ʻia nā plastics ʻaʻohe halogen no nā kaula.
He aha ke kaula halogen?
E like me kā lākou inoa e hōʻike nei, ʻaʻole halogen nā kaula halogen i ka haku ʻana o nā plastics.Hiki ke ʻike ʻia nā mea kemika i loko o ko lākou mau inoa, e like me ka polyvinyl chloride, chloroprene rubber, fluoroethylene propylene, fluoro polymer rubber, etc.
Inā makemake ʻoe a pono ʻoe e hoʻohana i nā uwea halogen-ʻole, e hoʻopaʻa pono i kēia mau mea i loko o nā plastic e like me ka rubber silicone, polyurethane, polyethylene, polyamide, polypropylene, thermoplastic elastomers (TPE) a i ʻole ethylene propylene diene rubber.ʻAʻole lākou i loko o nā mea hoʻopalekana a i ʻole nā mea hoʻoluʻu metala kaumaha, a ʻo nā mea hoʻohui no ka pale ʻana i ke ahi e palekana i ke kaiapuni.
Pehea e koho ʻia ai nā uwea halogen ʻole?
ʻAʻohe halogen ke kaula inā ʻaʻole hoʻohana ʻia nā halogen e like me ke chlorine, fluorine a i ʻole bromine i ka hoʻopulapula ʻana o ke kaula a me ka mea hoʻohu.ʻO nā ʻōpū uwea, nā ʻōnaehana hose, nā mea hoʻohui a i ʻole nā paipu liʻiliʻi, e like me kaHOOPAKOLO i ka paipu emi HFmai Mingxiu, hiki ke hana ʻia me nā plastics halogen-free a no laila ʻaʻole halogen.Inā makemake ʻoe i nā kaula halogen-free, no ka laʻana, e ʻoluʻolu e ʻoluʻolu i kēia mau inoa huahana:
| Pākīpika halogenated | ʻO nā mea iila halogen ʻole |
| Klorinephen-rubberʻO Fluorethylene Propylene Fluorplāʻau olymer PolyvinylʻO Chlormanaʻo | Lapa silikoniPolyurethane Polyethylene Polyamide Polypropylene Thermoplastic ʻO nā elastomers |
No ke aha he mea nui nā uwea halogen no ka pale ahi?
Hiki i nā halogen ke hōʻino i ke olakino.ʻO kēia ka hihia i ka wā e puhi ai nā plastic halogenated, ʻoi aku ka PVC.Inā ʻā ke ahi, hoʻokuʻu ʻia nā hydrogen halides mai ka plastic.Hoʻohui nā Halogens me ka wai, e like me ka wai hoʻopau i hoʻohana ʻia e ka brigade ahi a i ʻole ka wai mai ka mucous membranes, e hana i nā ʻakika - lilo ka chlorine hydrochloric acid, fluorine ka waika hydrofluoric corrosive loa.Eia kekahi, hiki ke hana ʻia kahi hui ʻana o nā dioxins a me nā mea ʻona ʻē aʻe.Inā komo lākou i loko o nā alaloa, hiki iā lākou ke hoʻopōʻino a hoʻohuehu.ʻOiai ke ola kekahi i ke ahi, hiki ke pōʻino mau loa ko lākou olakino.ʻOi aku ka liʻiliʻi o kēia no nā kaula halogen-free.
No ka pale ahi i hoʻohui ʻia, pono e loaʻa i nā kaula ka pale ahi a me ka hana ʻana o ka uahi haʻahaʻa.ʻO ka pale ʻana i ka lapalapa e hoʻolohi i ka puhi ʻana a me ka hoʻolaha ʻana o ka lapalapa a paipai i ka hoʻopau ʻana iā ia iho.Ke kū nei nā mea hana i kahi pilikia ma ʻaneʻi, no ka mea, ʻo ka chlorine a me ka bromine he mea pale ahi maikaʻi loa, ʻo ia ke kumu i hui pinepine ʻia me nā plastics no nā kaula.Eia nō naʻe, ma muli o nā pōʻino olakino i ʻōlelo ʻia, he hoʻopaʻapaʻa kēia a ʻae wale ʻia ma kahi ʻaʻohe poʻe i pilikia.ʻO ka hopena, hoʻohana ʻo Mingxiu i nā mea me kahi kiʻekiʻe o ka pale ahi akā ʻaʻohe halogen.
He aha ka maikaʻi o nā kaula halogen?
Inā wela nui a puhi ʻia nā kaula halogen ʻole, hana lākou i nā ʻakika corrosive a i ʻole nā kinoea e pōʻino i ke olakino.ʻO nā kaula XLPE a i ʻole nā uea ʻikepili mai ka Mingxiu he mea kūpono loa ia no ka hoʻohana ʻana i nā hale ākea, ka lawe ʻana a i ʻole ma kahi ākea kahi e hiki ai i ke ahi ke hōʻeha nui i nā kānaka a i ʻole nā holoholona a i ʻole nā waiwai.He haʻahaʻa ko lākou uwahi kinoea, no laila e hoʻoemi lākou i ka mahu a maʻalahi i ka poʻe i paʻa ke ʻimi i nā ala e pakele ai.
Pono pono nā kaula halogen-free inā makemake ʻoe e hōʻoiaʻiʻo i ka paʻa ʻana o ka hana i hiki ke loaʻa i ke ahi.He mea koʻikoʻi kēia ma nā hale kahi e hāʻawi ai nā kiʻi kiʻi kiʻi o ke kumu o ke ahi.Th kiʻekiʻe-wikiwiki uwea ikepili mai Mingxiu e hoʻouna i ka ikepili ma ka piha hoʻouna helu ma hope o elua hola i loko o ke ahi.
