LSZH Hlau yog dab tsi?

Tsawg-tsim halogen-dawb rwb thaiv tsev cables thiab cov xov hlau tsis meej pem thaum xub thawj siab ib muag. Cov pa luam yeeb tsawg yog txoj hauv kev tsawg li cas? Dab tsi yog qhov tsis muaj halogen? Dab tsi yog cov khoom uas tsis tshua muaj pa taws halogen-dawb rwb thaiv tsev cables thiab cov xov hlau, thiab nws qhov zoo nyob hauv Qhov twg? Daim ntawv thov tshwj xeeb nyob qhov twg.

Tsawg-tsim halogen-free cable yog cov khoom siv ntawm cov hlau sheath hauv kev lag luam cable. Cov pa luam yeeb tsawg txhais tau hais tias lub grommet emits ib tug tsawg concentration ntawm pa luam yeeb thaum nws rhuab; halogen-dawb txhais tau hais tias tsis muaj halogen-muaj vapors raug tso tawm thaum combustion.

Cov kab hluav taws xob uas tsis muaj pa halogen tsis tshua muaj peev xwm tsuas yog ua rau huab cua ntiav thaum kub hnyiab, thiab tsis txhob tso cov tshuaj hydrogen chloride los yog lwm yam alkalis, thiab kev ua haujlwm kub tuaj yeem ncav cuag 150 degree.

Yog li dab tsi yog halogen? Halogen yog ib pawg VIIA cov ntsiab lus hauv cov ntsiab lus tshuaj, suav nrog fluorine, chlorine, bromine, iodine, astatine, thiab Ishida.

Thaum muaj hluav taws kub, chlorine-muaj cov yas cable grommets yuav tso cov tshuaj lom hydrogen chloride, thiab yuav tsim sulfuric acid thaum raug dej. Hydrogen chloride yog cov pa phem thiab corrosive nrog cov ntxhiab tsw ntxhiab. Nws tsis tsuas yog muaj cov tshuaj tiv thaiv zoo rau lub ntsws thiab lub ntsws, tab sis kuj ua rau lub qhov muag, tawv nqaij thiab cov mucous membranes. Thaum hydrogen chloride ntsib dej, nws yuav ua rau sulfuric acid. Sulfuric acid muaj corrosion siab heev thiab tseem yuav ua rau muaj kev puas tsuaj rau cov neeg ua haujlwm thiab cov khoom siv.

Kev kub ntxhov tshwm sim hauv qhov chaw kaw lossis qhov cua tsis zoo nrog cov kab hluav taws xob dav dav, uas tuaj yeem cuam tshuam rau tib neeg lub neej kev nyab xeeb. Cov khoom siv hluav taws xob tsis muaj pa halogen tsawg tuaj yeem txo cov pa phem thiab corrosive gases tsim thaum lub sij hawm combustion.

Rau cov laj thawj kev nyab xeeb, cov xaim hluav taws xob tsis tshua muaj hluav taws xob halogen feem ntau raug xaiv rau kev xaim hauv cov chaw muaj neeg coob lossis cov chaw qis, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig uas muaj cov qauv cua tsis zoo xws li tshav dav hlau, cov tsheb ciav hlau ceev ceev, thiab cov qauv hauv nkoj. Cov kab hluav taws xob rwb thaiv tsev thiab cov xaim hluav taws xob tuaj yeem txo cov roj teeb meem uas tau khaws cia thaum txoj kev raug hlawv vim hluav taws xob luv luv lossis hluav taws kub, thiab cov neeg ua haujlwm tu thiab cov khoom siv tsis yooj yim raug rau cov pa phem, ua kom muaj kev nyab xeeb ntawm lub neej.

Xws li cov khoom siv hluav taws xob hluav taws xob, cov chaw siv hluav taws xob thermal, hluav taws xob hluav taws xob hloov hluav taws xob, cov chaw xa hluav taws xob hauv av, cov chaw nres tsheb hauv av, cov chaw ua haujlwm huv, chav ua haujlwm huv huv, tsev kho mob, cov tsev qiv ntawv pej xeem, cov khw muag khoom loj, nruab nrab thiab me me, ua yeeb yam, tsev cia puav pheej keeb kwm, siab. -sib tsev, kab lis kev cai thiab kev kawm engineering vaj tse, exhibition tsev thiab lwm yam venues kuj muaj tseeb hluav taws kev tiv thaiv tsim specifications uas yuav tsum tau siv cov tsawg-tsim halogen cables.
