Cov khoom siv teeb pom kev zoo sib txuas cov ntsaws ruaj ruaj feem ntau yog xa mus rau cov ntsaws ruaj ruaj uas siv los ntawm kev sib txuas cov pob qij txha kom ntseeg tau tias cov dej tsis zoo ntawm kev sib txuas. Cov roj hmab ntsaws ruaj ruaj no feem ntau yog lub nplhaib-puab thiab ua los ntawm cov khoom siv roj hmab tshwj xeeb nrog kev sib khi zoo dua thiab ua haujlwm ntev.
Lub hom phiaj ntawm cov roj hmab ntsaws ruaj ruaj no yog muab lub foob ntawm lub teeb pom kev sib txuas ntawm cov pob qij txha, tiv thaiv kom tsis txhob ya raws, plua plav, thiab lwm yam kab mob nkag mus rau sab hauv ntawm lub cuab yeej. Lawv feem ntau yog ntsia rau ntawm qhov chaw ntawm kev sib txuas los yog kos rau hauv qhov zawj ntawm qhov sib txuas ua ke los ua ib qho kev foob zoo.
Kev xaiv ntawm cov khoom siv roj hmab foob nyob ntawm qhov kev thov tshwj xeeb. Cov khoom siv roj hmab feem ntau yog
- Nitrile roj hmab: Nitrile roj hmab muaj cov roj ua haujlwm zoo, tiv thaiv kev puas tsuaj thiab tshuaj lom neeg, thiab tsim nyog rau kev sib khi daim ntaub ntawv ntawm cov khoom siv teeb pom kev zoo sib txuas.
- EPDM roj hmab: EPDM roj hmab muaj huab cua zoo heev, kev laus tiv thaiv thiab kub kub, thiab yog tsim rau sealing daim ntaub ntawv nyob rau hauv sab nraum zoov teeb pom kev zoo cov khoom sib txuas pob qij txha.
- Silicone roj hmab: Silicone roj hmab muaj qhov kub thiab txias tsis kam, ozone tsis kam thiab hluav taws xob rwb thaiv tsev, thiab yog tsim rau sealing daim ntaub ntawv ntawm cov pob qij txha ntawm high-temperature teeb pom kev zoo.
- Fluorine roj hmab: Cov roj hmab fluorine muaj cov tshuaj tiv thaiv zoo heev thiab kub kub ua haujlwm, thiab tsim nyog rau cov khoom siv teeb pom kev zoo sib txuas cov pob qij txha uas xav tau kev sib khi ua tau zoo hauv qhov chaw tshwj xeeb.
Cov roj hmab ntsaws ruaj ruaj no ua lub luag haujlwm tseem ceeb hauv cov khoom siv teeb pom kev zoo, ua kom cov dej tsis zoo ntawm cov khoom sib txuas, tiv thaiv cov dej noo, av noo thiab plua plav nkag mus rau hauv cov khoom siv sab hauv, thiab txhim kho kev ntseeg siab thiab kev pabcuam lub neej ntawm cov khoom siv.
Daim ntawv pov thawj ntawm cov ntsaws ruaj ruaj ntawm kev sib txuas teeb pom kev zoo feem ntau yuav tsum tau ua raws li ntau tus qauv thoob ntiaj teb los xyuas kom meej tias lawv cov kev ua tau zoo thiab kev ua tau zoo raws li cov kev cai thoob ntiaj teb.
- IP (Ingress Protection) qib ntawv pov thawj: IP qib ntawv pov thawj ntsuas lub foob lub peev xwm los tiv thaiv cov khoom siv (pua av) thiab kua (dej). Kev ntsuam xyuas IP feem ntau pib nrog "IP" ua raws li ob tus lej, xws li IP65. Thawj tus lej qhia txog kev tiv thaiv plua plav, thiab tus lej thib ob qhia txog kev tiv thaiv dej. Cov qauv ntawv pov thawj no yog tsim los ntawm International Electrotechnical Commission (IEC).
- UL (Underwriters Laboratories) daim ntawv pov thawj: UL ntawv pov thawj yog daim ntawv pov thawj kev nyab xeeb uas muab los ntawm Underwriters Laboratories hauv Tebchaws Meskas, thiab tsim nyog rau kev soj ntsuam kev nyab xeeb ntawm cov khoom. UL ntawv pov thawj feem ntau muaj xws li kev ruaj ntseg hluav taws xob ntawm cov khoom, hluav taws kub ua haujlwm thiab huab cua tsis kam ntawm cov khoom.
- EN (European Norm) daim ntawv pov thawj tus qauv: EN cov qauv yog cov qauv kev coj ua uas tau txais los ntawm cov tebchaws nyob sab Europe, suav nrog kev nyab xeeb thiab kev ua haujlwm ntawm cov khoom siv tshuab, hluav taws xob thiab hluav taws xob. Lub teeb pom kev sib koom ua ke yuav tsum ua raws li cov qauv EN tshwj xeeb kom ua tau raws li European kev ua lag luam.
- Daim ntawv pov thawj RoHS (Kev txwv tsis pub muaj phom sij) daim ntawv pov thawj: RoHS daim ntawv pov thawj yog hais txog kev ua raws li cov cai ntawm EU RoHS cov lus qhia, uas yog, Txoj Cai Lij Choj Cov Tshuaj Tiv Thaiv Kab Mob. Daim ntawv pov thawj no ua kom ntseeg tau tias cov khoom siv hauv cov khoom tsis muaj cov khoom tsis zoo xws li txhuas, mercury, cadmium, hexavalent chromium, thiab lwm yam.
- ISO (International Organization for Standardization) certification: ISO certification yog ib daim ntawv pov thawj thoob ntiaj teb uas muaj ntau yam kev lag luam thiab kev lag luam. Cov ntsaws ruaj ruaj rau cov khoom siv teeb pom kev sib txuas yuav tsum tau ua raws li cov qauv ISO, xws li ISO 9001 (Quality Management System Certification) thiab ISO 14001 (Environmental Management System Certification).
Nws yuav tsum raug sau tseg tias cov ntawv pov thawj tshwj xeeb yuav txawv raws li cov cai thiab cov qauv hauv ntau lub tebchaws thiab cheeb tsam.
