Cov khoom siv txuas, yog ib qho tseem ceeb ntawm ntau yam lag luam, muaj lub ntsiab lus tseem ceeb heev rau kev ua kom muaj kev ruaj khov thiab kev nyab xeeb ntawm ntau yam kev siv. Txhawm rau kom muaj kev sib npaug, kev ntseeg siab, thiab kev lav phib xaub rau ib puag ncig,cov khoom siv txuasua raws li cov qauv txheej txheem. Cov qauv no, uas suav nrog qhov ntev, cov khoom siv, kev kho qhov chaw, kev ua haujlwm ntawm lub tshuab, kev tswj xyuas zoo, thiab cov yam ntxwv ib puag ncig, ua lub luag haujlwm tseem ceeb hauv kev lav qhov zoo thiab kev ruaj khov ntawm cov khoom siv txuas.
Cov qauv ntsuas qhov ntev yog qhov tseem ceeb rau cov txheej txheem tsim cov khoom siv sib txuas. Cov no suav nrog cov qhov ntev tseem ceeb, kev kam rau siab, thiab cov lej sib xws rau ntau hom khoom siv sib txuas. Cov qauv ntsuas qhov ntev uas tau lees paub dav dav xws li GB/T, ISO, thiab ANSI/ASME muab cov lus qhia rau kev sib xws ntawm qhov ntev, ua rau cov chaw tsim khoom tsim cov khoom siv sib txuas uas ua tau raws li cov lus qhia meej.
Cov qauv khoom siv qhia txog cov hom khoom siv uas siv tau rau cov khoom siv txuas. Kev koom ua ke ntawm cov txheej txheem xaiv, cov qauv no suav nrog cov hlau, cov hlau tsis yog hlau, thiab cov yas, kom ntseeg tau tias tsuas yog siv cov khoom zoo thiab tsim nyog. GB/T, ISO, thiab ASTM yog cov qauv khoom siv uas coj cov chaw tsim khoom xaiv cov khoom siv tsim nyog, tiv thaiv cov khoom tsis zoo lossis tsis sib xws los ntawm kev cuam tshuam rau kev ua haujlwm tag nrho ntawm cov khoom siv txuas.
Cov qauv kev kho saum npoo tswj hwm cov txheej txheem thiab cov kev cai siv los txhim kho qhov ruaj khov, tiv taus corrosion, thiab qhov zoo nkauj ntawm cov fasteners. Cov qauv no npog ntau yam txheej txheem xws li galvanizing, phosphating, anodizing, thiab txau. Los ntawm kev ua raws li cov qauv kev kho saum npoo xws li GB / T, ISO, thiab ASTM, cov chaw tsim khoom tuaj yeem vam khom cov txheej txheem pov thawj los tiv thaiv cov fasteners los ntawm kev puas tsuaj ntawm ib puag ncig thiab xyuas kom meej tias lawv lub neej ntev.
Cov qauv kev ua haujlwm ntawm lub tshuab yog qhov tseem ceeb heev rau kev ntsuam xyuas lub zog, qhov nyuaj, lub zog torque, thiab lwm yam khoom siv ntawm cov fasteners. Cov qauv no, feem ntau txiav txim siab los ntawm kev sim ua tib zoo, ntsuas qhov kev ntseeg tau thiab kev ua tau zoo ntawm cov fasteners hauv cov xwm txheej nyuaj. GB / T, ISO, thiab ASTM cov qauv khoom siv tshuab tsim cov qauv rau cov chaw tsim khoom los tsim cov fasteners uas qhia txog kev ua haujlwm ntawm lub tshuab thiab ua tau raws li cov kev xav tau tshwj xeeb ntawm ntau yam lag luam.
Cov qauv tswj xyuas zoo ua kom cov khoom siv sib txuas tau dhau los ntawm kev tshuaj xyuas thiab kuaj xyuas kom zoo kom lav lawv qhov zoo tag nrho. Cov qauv no suav nrog ntau yam xws li qhov tsos, qhov loj me, cov khoom siv kho tshuab, thiab kev kho qhov chaw. Los ntawm kev ua raws li cov qauv tswj xyuas zoo xws li GB / T, ISO, thiab ASTM, cov chaw tsim khoom tuaj yeem siv cov kev ntsuas tswj xyuas zoo thoob plaws hauv cov txheej txheem tsim khoom, txo qhov yuav muaj qhov tsis zoo lossis tsis txaus ntawm cov khoom siv sib txuas uas ua rau daim ntawv thov tsis zoo.
Cov qauv kev tiv thaiv ib puag ncig tsom mus rau kev txo qis qhov cuam tshuam rau ib puag ncig ntawm cov fasteners thoob plaws lawv lub neej. Cov qauv no hais txog kev xaiv cov khoom siv, cov txheej txheem kho qhov chaw, thiab kev pov tseg pov tseg, ntawm lwm yam. Cov qauv zoo li RoHS thiab REACH lub hom phiaj yog txo cov tshuaj lom neeg, txhawb kev tsim khoom kom ruaj khov, thiab txhawb kom muaj cov txheej txheem pov tseg kom raug. Kev ua raws li cov qauv ib puag ncig no ua rau cov chaw tsim khoom tsim cov fasteners uas tsis yog tsuas yog txhim khu kev qha xwb tab sis kuj muaj lub luag haujlwm rau ib puag ncig.
Xaus lus, kev ua raws li cov qauv rau cov khoom siv sib txuas ua kom lawv zoo, ntseeg tau, thiab ua raws li ib puag ncig. Cov qauv no suav nrog ntau qhov ntev, cov ntaub ntawv, kev kho qhov chaw, cov ntsuas kev ua haujlwm, cov kev cai tswj hwm zoo, thiab cov lus qhia kev tiv thaiv ib puag ncig. Los ntawm kev ua raws li cov qauv no xws li GB / T, ISO, ASTM, RoHS, thiab REACH, cov chaw tsim khoom tuaj yeem tsim cov khoom siv sib txuas uas ua tau raws li kev cia siab ntawm kev lag luam, pab txhawb rau kev siv nyab xeeb thiab ua haujlwm tau zoo, thiab txo lawv cov teeb meem ecological.
