Kev tuav pov hwm kev ua haujlwm khau yog khau uas muaj kev tiv thaiv ntawm ko taw. Muaj ntau hom, xws li kev tiv thaiv ntawm cov ntiv taw, puncture resistance, rwb thaiv tsev, acid thiab alkali tsis kam. Kev xaiv cov khau kev tuav pov hwm kev ua haujlwm yuav tsum ua raws li qhov xwm txheej ntawm qhov chaw ua haujlwm thiab qib ntawm kev phom sij. Kev tuav pov hwm kev ua haujlwm khau yuav tsum muaj daim ntawv pov thawj khoom thiab cov khoom tshwj xeeb. Nyeem cov lus qhia ua ntej siv, thiab siv txoj kev kom raug. Cov khau tiv thaiv tshwj xeeb yuav tsum tau kuaj xyuas thiab ua kom huv si tom qab siv thiab khaws cia rau hauv qhov chaw tsis muaj kuab lom thiab qhuav.
Kev faib tawm thiab kev ua haujlwm ntawm kev tuav pov hwm cov khau ua haujlwm
Kev tuav pov hwm kev ua haujlwm khau feem ntau muab faib ua: cov khau tiv thaiv kev ua haujlwm tiv thaiv kev ua haujlwm, khau tiv thaiv kev sib tsoo thiab cov khau hluav taws xob tiv thaiv hluav taws xob (nrog voltage> 6 kV).
Cov khau tiv thaiv smashing thiab cov khau steel-toed steel yog tib yam, uas yog, cov khau kev nyab xeeb uas tiv thaiv cov ntiv taw, thiab lub luag haujlwm tseem ceeb yog tiv thaiv cov khoom poob los ntawm kev mob ntawm ko taw.
Cov khau tiv thaiv kev tiv thaiv yog siv rau kev tiv thaiv ko taw kom tiv thaiv qhov txhab los ntawm ntau yam khoom ntse.
Lwm tus nyob ntawm lub sijhawm siv thiab kev siv tshwj xeeb ntawm cov khau tiv thaiv, kuj tseem muaj cov ntsiab lus:
Roj-pov thawj khau tiv thaiv yog siv nyob rau hauv qhov chaw uas muaj roj los yog roj txaws;
Cov khau tiv thaiv tsis muaj dej yog siv rau hauv cov chaw ua haujlwm uas siv dej los yog dej txaws;
Cov khau tiv thaiv khaub thuas yog siv rau kev tiv thaiv ko taw ntawm cov neeg ua haujlwm kub los tiv thaiv frostbite.
Lub luag haujlwm tseem ceeb ntawm steel-ua kev tuav pov hwm kev ua haujlwm khau yog tiv thaiv kev kub nyhiab thiab punctures. Nws yuav tsum muaj peev xwm tiv taus qee qhov zoo li qub thiab tiv taus qee qhov kub thiab tsis muaj hluav taws kub. Hom kev tuav pov hwm kev ua haujlwm khau no yog tsim rau smelting, furnace, cam khwb cia hlau thiab lwm yam.
Ntxiv rau qhov saum toj no, muaj qee qhov tshwj xeeb kev tuav pov hwm kev ua haujlwm khau npog, xws li canvas, asbestos, thiab txhuas-cov ntaub ntawv pov hwm kev ua haujlwm khau npog. Qhov kev xaiv tseem ceeb rau kev tuav pov hwm cov khau ua haujlwm nyob ntawm seb cov chaw tsim khoom puas tau txais "National Industrial Product Production License" thiab "LA Safety Mark Certification". Puas muaj daim ntawv qhia txog cov qauv tsim nyog, seb txoj kev xeem puas yog, thiab seb qhov tshwm sim puas muaj tseeb.
Kev soj ntsuam kev ua haujlwm ntawm kev tuav pov hwm khau ua haujlwm
Baotou cuam tshuam tsis kam
Qhov kev ntsuam xyuas qhov cuam tshuam yuav tsum tau ua nrog ib qho kev cuam tshuam rau steel ntawm qhov hnyav uas tau teev tseg. Qhov siab ntawm qhov sib txawv nyob rau hauv tus ntiv taw cap yuav tsum tsawg tshaj li tus nqi teev thaum lub hau ntiv taw raug cuam tshuam, thiab qhov tho qhov yuav tsum tsis txhob pom cov kab nrib pleb nkag mus rau hauv cov kev taw qhia ntawm qhov ntsuas axis. Nws yog tsim nyog sau cia tias lub teb chaws cov qauv muaj cov kev cai sib txawv ntawm qhov hnyav, specifications, cuam tshuam qhov siab thiab kev tsim kho ntawm lub tshuab kuaj. Qhov kev xeem tiag tiag yuav tsum tau paub qhov txawv.
Puncture kuj
Lub tshuab kuaj tau nruab nrog lub phaj siab uas lub ntsuas ntsia hlau ntsia. Cov ntsia hlau xeem yog lub taub hau nrog lub hau txiav, thiab qhov tawv ntawm tus ntsia thawv taub hau yuav tsum siab dua 60HRC. Cov qauv ib leeg yog muab tso rau ntawm lub chassis ntawm lub tshuab kuaj nyob rau hauv xws li ib txoj hauj lwm uas cov ntsia hlau xeem yuav pierced los ntawm lub outsole, thiab cov ntsia hlau xeem pierces tus ib leeg ntawm ib tug ceev ntawm 10 mm / min ± 3 mm / min kom txog rau thaum nkag mus. ua tiav. Lub zog loj. Plaub lub ntsiab lus raug xaiv rau ntawm ib leeg rau kev sim (tsawg kawg yog ib qho ntawm lub pob taws), txhua qhov taw qhia tsis tsawg dua 30 mm sib nrug, thiab qhov kev ncua deb ntawm sab hauv qab ntug yog ntau dua 10 mm. Hauv qab ntawm qhov thaiv thaiv yuav tsum tau tho qhov nruab nrab ntawm cov blocks. Ob ntawm plaub lub ntsiab lus yuav tsum tau sim nyob rau hauv 10-15 hli ntawm ntug kab ntawm hauv qab ntawm cov nroj tsuag. Yog tias cov av noo cuam tshuam rau qhov tshwm sim, ib leeg yuav tsum tau muab tso rau hauv dej deionized ntawm 20 degree ± 2 degree rau 16 ± 1 h ua ntej kuaj.
Hluav taws xob cov khoom ntawm cov khau conductive thiab khau tiv thaiv static
Tom qab cov qauv khau tau hloov kho nyob rau hauv qhov chaw qhuav thiab ntub dej, lub pob hlau huv huv tau ntim rau hauv tib neeg cov khau thiab muab tso rau ntawm cov khoom siv hlau sojntsuam, thiab thawj ob qhov kev sojntsuam thiab qhov thib peb kev sojntsuam yog ntsuas los ntawm kev ntsuas cov tshuaj tiv thaiv. Kev tiv thaiv ntawm. Raws li ib txwm muaj, cov khau conductive yuav tsum tsis txhob siab dua l00K ohms; Cov khau tiv thaiv zoo li qub yuav tsum muaj kev tiv thaiv yuav tsum nyob nruab nrab ntawm 100K ohms thiab 100M ohms.
Kev xaiv cov khau kev tuav pov hwm kev ua haujlwm yuav tsum ua raws li qhov xwm txheej ntawm qhov chaw ua haujlwm thiab qib ntawm kev phom sij. Kev tuav pov hwm kev ua haujlwm khau yuav tsum muaj daim ntawv pov thawj khoom thiab cov khoom tshwj xeeb. Nyeem cov lus qhia ua ntej siv, thiab siv txoj kev kom raug. Cov khau tiv thaiv tshwj xeeb yuav tsum tau kuaj xyuas thiab ua kom huv si tom qab siv thiab khaws cia rau hauv qhov chaw tsis muaj kuab lom thiab qhuav.
