Kev Siv Cov Hluav Taws Xob Hluav Taws Xob kom raug: Tsis txhob cia "Kev Tiv Thaiv Hluav Taws Xob" tig mus rau "Hidden Hazard"

 

Hluav taws yog ib qho ntawm tib neeg txoj kev ntshai tshaj plaws thiab cov yeeb ncuab phem tshaj plaws. Hauv peb txoj kev nrhiav tsis tu ncua los tswj lub zog tseem ceeb no, peb tau tsim cov chav muaj zog tiv thaiv: Cov tshuaj tiv thaiv hluav taws. Los ntawm cov pob txha steel ntawm cov skyscrapers mus rau cov ntaub ntawm peb lub rooj zaum, cov qauv tshuaj no yog cov neeg saib xyuas ntsiag to, tsim los tiv thaiv hluav taws kub, qeeb nplaim taws, thiab yuav lub sijhawm muaj txiaj ntsig rau kev khiav dim thiab cawm. Lawv yog lub hauv paus ntawm kev nyab xeeb niaj hnub, ib qho zoo tsis txaus ntseeg hauv kev tawm tsam kev puas tsuaj.

Txawm li cas los xij, qhov txaus ntshai paradox nyob hauv qhov lus piav qhia ntawm kev tiv thaiv. Thaum xaiv, siv, lossis khaws cia tsis raug, cov khoom siv los tiv thaiv peb tuaj yeem hloov mus rau hauv cov kev phom sij zais, cuam tshuam kev noj qab haus huv, ua rau muaj kev ncaj ncees ntawm cov qauv, thiab tseem ua rau muaj kev phom sij loj heev hauv hluav taws. Kev nkag siab txog kev siv cov tshuaj tua hluav taws kom raug tsis yog ib qho kev ua haujlwm rau cov engineers xwb; nws yog ib qho tseem ceeb ntawm kev nyab xeeb rau pej xeem, kom ntseeg tau tias peb thawj kab ntawm kev tiv thaiv tsis dhau los ua peb qhov tsis ua.

Ntaj Ob-Edged: Kev Tiv Thaiv vs

Yuav kom txaus siab rau qhov tseem ceeb ntawm kev siv kom raug, peb yuav tsum xub to taub dab tsi Cov tshuaj tiv thaiv hluav taws yog tsim los ua. Lawv ua hauj lwm los ntawm ntau yam mechanisms:

• Intumescent Coatings: Cov no yog hom ntau tshaj plaws rau cov qauv hlau. Thaum raug tshav kub, lawv swell los ua ib tug tuab, insulating char, tiv thaiv cov khoom siv los ntawm qhov kub thiab txias thiab tiv thaiv kom tsis txhob poob nws load-bearing peev.

• Endothermic Coatings: Cov no muaj cov tshuaj (xws li hydrates) uas tso dej vapor los yog nqus cua sov thaum cua sov, ua kom txias rau qhov chaw tiv thaiv thiab ncua nws qhov kub thiab txias.

• Flame Retardants (rau textiles thiab plastics): Cov tshuaj no cuam tshuam cov txheej txheem combustion ntawm cov tshuaj lom neeg, xws li diluting flammable gases, tsim cov txheej txheem tiv thaiv char, los yog tshem tawm cov dawb radicals uas propagate nplaim taws.

Kev phom sij tshwm sim thaum cov txheej txheem tiv thaiv no raug cuam tshuam. Ib daim ntawv thov tsis raug tuaj yeem txhais tau tias yog txheej txheej uas ua tsis tau rau hauv hluav taws tiag tiag. Ntau insidiously, qee cov neeg ua pov thawj hluav taws, tshwj xeeb yog cov nplaim hluav taws halogenated, tuaj yeem tso cov pa phem xws li carbon monoxide, hydrogen cyanide, thiab ntom ntom, tsis muaj pa taws thaum lawv hlawv lossis kub hnyiab. Qhov kev txaus ntshai tiag tiag yog tias nyob rau hauv ntau qhov hluav taws kub, kev nqus pa thiab toxicity, tsis yog nplaim taws lawv tus kheej, yog thawj qhov ua rau tuag taus. Yog li ntawd, cov tshuaj tiv thaiv hluav taws uas ncua kev siv hluav taws xob tab sis tom qab ntawd ua rau muaj qhov muaj kuab lom muaj, hauv qhov tseem ceeb, ua tsis tiav.

Lub Spectrum ntawm Hidden Hazards

Kev siv tsis raug ntawm cov neeg tua hluav taws ua pov thawj tshwm sim hauv ntau txoj hauv kev, txhua qhov tsim kom muaj "kev phom sij zais."

1. Kev Nyab Xeeb Kev Nyab Xeeb: Tawm-Gassing thiab cua hauv tsev zoo

Qhov no yog qhov uas ntsiag to, muaj kev phom sij uas cuam tshuam feem ntau nrog qee yam tsis muaj zog ntawm cov organic compound (VOC)-raws li txheej thiab qee cov hluavtaws hluavtaws siv hauv rooj tog thiab rwb thaiv tsev. Thaum siv sab hauv tsev, cov khoom no tuaj yeem txuas ntxiv mus rau "tawm-kub" tshuaj lom neeg ntev tom qab daim ntawv thov qhuav. Cov khoom xws li formaldehyde, benzene, thiab qee yam nplaim taws retardants (PBDEs) tau txuas rau ntau yam teeb meem kev noj qab haus huv, suav nrog:

• Teeb meem ua pa thiab mob hawb pob

• Kev cuam tshuam ntawm endocrine

• Neurological txoj kev loj hlob ntawm cov me nyuam

Thov nws thinly heev yog zoo li hnav lub tsho tiv nag uas muaj qhov; nws yuav zoo li kev tiv thaiv tab sis yuav ua tsis tiav nyob rau hauv siab.

• Kev npaj deg tsis zoo: Cov hlau yuav tsum huv thiab tsis muaj xeb, roj, thiab zeb nplai. Kev siv cov txheej txheej intumescent tshaj qhov tsis huv yuav ua rau cov adhesion tsis zoo, ua rau cov txheej txheem delaminate thiab tev tawm ntev ua ntej qhov hluav taws kub pib, lossis tsis nthuav dav sib xws thaum rhuab.

• Incompatibility nrog Primers / Topcoats: Cov kab hluav taws pov thawj feem ntau yog ib feem ntawm ntau txheej txheej. Kev siv cov primer tsis sib xws lossis cov tsho zoo nkauj zoo nkauj tuaj yeem tiv thaiv cov txheej txheem intumescent los ntawm qhov o kom raug, ua rau nws muaj peev xwm tiv thaiv tau zoo.

Tsis tas li ntawd, kev saib xyuas feem ntau tsis saib xyuas. Hauv ib lub tsev lag luam uas tibneeg hu tauj coob, steel beams feem ntau yog siv los ua cov ntsiab lus rau cov kav dej tshiab, cov kav dej, lossis cov cables. Drilling rau hauv ib lub nqaj scrapes tawm ntawm qhov hluav taws kub-pov thawj, tsim kom muaj qhov chaw tsis muaj zog tiv thaiv. Thaum hluav taws kub, ib lub nqaj no tuaj yeem ua kom sov thiab ua tsis tau sai, ua rau muaj kev sib tsoo.

3. Kev Nyab Xeeb Ib puag ncig: Kev pheej hmoo thiab kev ua qias tuaj

Qee cov neeg laus ntawm cov nplaim hluav taws halogenated yog cov tsis muaj kuab lom tsis zoo (POPs). Lawv tsis tawg yooj yim hauv ib puag ncig thiab tuaj yeem bioaccumulate hauv cov khoom noj khoom haus. Thaum cov khoom uas muaj cov tshuaj no pov tseg, lawv tuaj yeem nkag mus rau hauv av thiab dej hauv av. Hauv qhov xwm txheej tswj kev pov tseg, yog tias lawv raug hlawv, lawv tuaj yeem tso cov dioxins thiab furans, uas yog cov tshuaj lom thiab carcinogenic. Siv cov neeg ua haujlwm zoo li no, tshwj xeeb tshaj yog thaum muaj kev nyab xeeb dua lwm txoj hauv kev, ua lag luam ib lub tsev muaj kev nyab xeeb rau kev puas tsuaj ib puag ncig mus ntev.

4. Kev Ruaj Ntseg Tsis Muaj Kev Nyab Xeeb

Tej zaum qhov kev puas siab puas ntsws tshaj plaws ntawm kev phom sij yog kev txaus siab uas qhov hluav taws kub-pov thawj tuaj yeem tsim. Cov neeg nyob hauv tsev thiab txawm tias cov thawj coj tuaj yeem ua haujlwm raws li qhov kev xav tias vim tias cov khoom siv "pov thawj hluav taws," nws yog invulnerable. Qhov no tuaj yeem ua rau muaj kev coj cwj pwm tsis zoo rau lwm cov txheej txheem kev nyab xeeb hluav taws - kev tu vaj tse tsis zoo, thaiv qhov hluav taws kub tawm, lossis lub tswb tsis muaj pa taws. Kev tiv thaiv hluav taws kub yog qhov ua haujlwm tsis zoo; Nws yog txhais tau tias ua haujlwm hauv kev hais kwv txhiaj nrog cov tshuab ua haujlwm zoo li cov twj tso kua mis, lub tswb, thiab cov phiaj xwm khiav tawm tau zoo. Kev cia siab dhau ntawm ib txheej ntawm kev tiv thaiv yog ib daim ntawv qhia rau kev puas tsuaj.
