Cov khoom siv rau chaw nres tsho zoo hauv duab rau siv ntev rau kev tsim khaws tsev kev lag luam

Yam twg “nyab xeeb” txawv li cas rau tsev kawm

Nyob rau hauv kev xaiv tshuaj ntsuab, cov khoom sib xyaw rau hauv qhov chaw nyob ntawm lub tsev thiab lub tsev kawg yuav tsum tau txais kev sib xyaw ntau dua li cov khoom sib xyaw rau hauv tsev nyob. Ib qho khoom sib xyaw rau hauv qhov chaw nyob rau hauv lub tsev hotel yuav tsum tau sib xyaw ntau dua 100 zaug ib hnub, thiab ntau zaug yog cov neeg siv nws ua rau muaj kev nyab xeeb. Ib qho khoom sib xyaw rau hauv qhov chaw nyob rau hauv lub tsev nyob rau hauv lub tsev kawg yuav tsum tau sib xyaw los ntawm hluav taws tshiab mus rau hluav taws nqaij ntau zaug ib lub caij. Qhov txaus siab tsis yog tias yuav tsum tau nyob tau, tab sis yog tias yuav tsum tau nyob tau thiab tsis muaj kev puas tsuaj rau cov ntaub ntawv, cov ntawv sib xyaw, thiab cov khoom uas yuav tsum tau sib xyaw tau zoo ib yam li thaum kawg. Cov neeg xaiv tshuaj ntsuab uas muaj kev nyab xeeb rau hauv kev xaiv tshuaj ntsuab tau muab qhov txaus siab rau cov khoom no, thiab qhov txaus siab Grade 1 yog qhov txaus siab pheej yig rau cov khoom uas yuav tsum tau nyob tau rau hauv cov chaw uas muaj neeg nyob ntau. Qhov txaus siab Grade 2 lossis cov khoom sib xyaw rau hauv tsev nyob yuav tsum tau nyob tau ntau dua, thiab ntau zaug yog rau hauv cov chaw sib xyaw lossis rau hauv cov ntaub ntawv.

Cov ntaub ntawv sib xyaw uas yuav tsum tau nyob tau rau hauv kev sib xyaw ntau

Tshuaj saib xyuam rau hauv tsev siv nyob rau hauv qhov chaw siv nyob ntau dua li cov tshuaj saib xyuam rau hauv tsev siv nyob rau hauv tsev. Cov tshuaj quaternary ammonium compounds, tshuaj bleach-based sprays, thiab tshuaj acid descalers yuav puv cov ntaub ntawv lacquer rau hauv peb lub hlis. Ob qhov kev ua ntaub ntawv yuav txaus siab rau no: 304 stainless steel uas muaj cov ntaub ntawv brushed lossis satin, thiab brass lossis zinc uas muaj cov ntaub ntawv PVD-coated. PVD, lossis physical vapor deposition, yog qhov kev ua kom cov ntaub ntawv txias tau pab los ntawm cov ntaub ntawv ntau, uas yog qhov txaus siab dua li kev ua ntaub ntawv electroplating. Ib qhov kev suav nrog lub 2019 los ntawm American Architectural Manufacturers Association tau pom tias cov ntaub ntawv PVD rau brass tau tswj xyuam rau 1,000 teev ntawm salt spray exposure, thaum li cas cov ntaub ntawv chrome plating tuaj yeem pom tias muaj cov ntaub ntawv pitting rau 400 teev.

Lub tshuab yam tias los ntawm kev kho lub tsev siab

Lub tsev kho los ntawm lub tsev ua haujlwm rau lub tsev nyob hauv Chicago, uas muaj 22 sab, tau ploj txog ntau yam thaum muaj ib lub lis piam tom qab tshuab. Lub tshuab thib cim tau xav kom muaj cov khoom siv rau kev tswj lub tsev thiab cov khoom siv rau kev saib xyuas lub tsev uas muaj cov ntawv tsis muaj duab (chrome) rau tag nrho cov tsev 212. Thaum muaj ib lub lis piam, cov ntawv tsis muaj duab (chrome) nyob rau hauv qhov chaw tswj lub tsev tau muaj cov ntawv tsis muaj duab (rust) thiab cov khoom siv rau kev saib xyuas lub tsev tau muaj kev nyuaj rau hauv qhov chaw sib tshooj. Qhov teeb meem tsis yog cov khoom siv, tab sis yog qhov sib nplog ntawm cov khoom siv rau kev sib tshooj rau lub tsev uas tsis zoo thiab cov khoom siv rau kev saib xyuas uas muaj kev nyuaj rau lub tsev uas cov neeg saib xyuas lub tsev siv. Qhov kev kho tau xav kom muaj kev kho tag nrho cov khoom siv uas muaj cov ntawv 304 stainless thiab muaj cov khoom siv rau kev sib tshooj zoo, thiab kho cov lus qhia rau kev saib xyuas lub tsev mus rau cov khoom siv uas muaj pH tshwj xeeb. Qhov nqi rau kev kho tag nrho tau muaj ntau dua 100,000, uas yuav tau muaj kev kho ntxiv thaum lub cim tshuab, yog tias muaj kev xaiv cov khoom siv zoo dua thaum lub cim tshuab. Lub tshuab no tau qhia cov neeg nyob ntawm lub tshuab txog kev xav txog lub tsev raws li qhov kev nyob ntawm lub tsev rau ntau lub lis piam.

Cov lus qhia rau kev sib tshooj thiab cov lus qhia rau kev sib tshooj uas ntau yam tshuab tsis muaj

Yog li cov khoom siv rau hauv tsev ua noj tsuas yog qhov zoo tshaj plaws, tab sis nws yuav tsis tuaj yeem siv tau yog tias nws tau muab sau rau hauv qhov chaw uas tsis zoo. Cov khoom siv uas muab sau rau hauv tsev ua noj uas muaj kev sib koom tes yuav tsum tuaj yeem tso cia lub weight 250 pounds thiab tsis txhob rov qab los sis thiab tsis txhob tawm los sis, raws li cov kev daws teb ntawm ADA rau kev sib koom tes. Qhov kev daws teb no txhais hais tias qhov chaw hauv qab ntawm lub tsev yuav tsum yog lub plywood lossis lub block zoo, tsis yog lub drywall anchors uas muaj hluav taws. Ntau yam tsev siv rau kev lag luam muaj kev xaiv nyob rau hauv qhov kev xaiv no, thiab cov neeg siv drywall yuav sau lub block yog tias cov lus qhia nyob rau hauv cov lus qhia muaj qhia tias yuav tsum sau. Yog tias cov khoom siv tau muab sau rau hauv qhov chaw uas tsis zoo tom qab qhov chaw tau muab sau, qhov chaw hauv qab yuav tsis tau muab sau rau hauv qhov chaw uas tsis zoo. Qhov kev ua siab zoo tshaj plaws yog tias yuav tsum muab cov khoom siv sau rau hauv qhov chaw ua ntej yuav tsum sau drywall, thiab tom qab ntawd yuav tsum muab cov duab qhia tias cov block tau muab sau rau hauv qhov chaw ua ntej yuav tsum sau lub tsev. Qhov no yuav muab ntxiv qhov sijhawm ua haujlwm ob peb hou, tab sis nws yuav pab tshem qhov kev ua dua thiab kev ua dua tom ntej.

Qhov nqi thiab qhov sijhawm ua dua rau cov kev lag luam nyob rau hauv sijhawm ntev

Tus neeg siv nyiaj rau kev xaum ua haujlwm yuav tsum nrhiav xyuam ntau dua li qhov ntaub ntawv ntawm qhov ntaub ntawv, tab sis qhov kev xav no tsis tuaj yeem txog qhov loj dua. Ib qho khaub ncaws rau lub tshuab yuav muaj ntaub ntawv $18, tab sis ib qho khaub ncaws rau lub tshuab uas muaj qhov ntaub ntawv zoo heev yuav muaj ntaub ntawv $55. Rau ib qho tsev uas muaj 100 qhov tsev, qhov ntaub ntawv ntsiab yuav muaj $3,700 rau khaub ncaws xwb. Yog tias 10 peb cent ntawm cov khaub ncaws uas muaj ntaub ntawv tsis loj yuav tsum tau muab los ua dua tom qab rov ua dua ntawm peb xyoo los no vim qhov ntaub ntawv tsis zoo lossis qhov khaub ncaws tsis nyob deb, qhov ntaub ntawv rau kev ua haujlwm yuav tsum muaj ntau dua $75 rau ib qho khaub ncaws hauv ib qho tsev uas loj heev vim tus neeg ua haujlwm yuav tsum sau lub sijhawm rau kev mus nrhiav tsev thiab muab cov khoom los ua haujlwm los ntawm ntau qhov tsev. Tus neeg saib xyuam cov khoom rau ntau qhov tsev yuav tsum hais tias qhov ntaub ntawv rau kev muab cov khoom los ua dua yuav ntau dua li 3-5 zaug ntawm qhov ntaub ntawv rau cov khoom. Thaum muaj ib qho sijhawm 10 xyoo, cov khoom uas muaj ntaub ntawv loj dua yuav tsum muaj qhov ntaub ntawv tsis loj dua thaum muaj kev ua haujlwm tag nrho.

Yog twb yuav tsum nug cov neeg muab khoom ua ntej koj txhawj xyuam

Kab laj tshuaj yuav pab txhawj xyuam cov khoom sib tw uas tsis tuaj yeem nyob hauv qhov kev sib tw. Thov xyuam rau BHMA grade rau txhua qhov ntsiab uas muaj kev sib tw, tsis yog tsiag xwb. Thov xyuam cov lus qhia ntawm salt spray test yog tias lub tsev yuav siv cov khoom sib tw uas muaj kev sib tw heev. Tso cai tias cov template uas siv los txhawj xyuam yuav tsum muaj cov lus qhia txog qhov ntsiab uas yuav tsum muaj rau hauv qhov ntsiab, thiab xyuam kom paub tias cov khoom sib tw uas yuav siv los kho yuav muaj nyob rau hauv 5 xyoo. Tsis tas li ntawd, xyuam kom paub tias tus neeg siv khoom yuav tuaj yeem muaj kev sib tw zoo ib yam rau txhua qhov ntsiab, vim tias kev kho tsev rau cov tsev siv los ntawm cov neeg siv tsev tsis tau ua tag nrho ib zaug. Wiselink muaj kev sib tw zoo rau no, vim tias lawv muaj cov khoom sib tw uas muaj kev sib tw zoo thiab cov neeg tshuaj xyuam uas xyuam kom paub tias cov khoom sib tw yuav sib tw zoo rau qhov chaw uas yuav siv. Qhov kev sib tw ntawd pab cov neeg siv khoom tsis tau siv ntau ntau nyob rau hauv qhov kev sib tw.
