Txawm hais tias peb xav tsim cov nplaum los yog yuav cov nplaum nplaum, peb feem ntau pom tias qee cov nplaum nplaum yuav muaj ntawv pov thawj ROHS, NFS ntawv pov thawj, nrog rau cov thermal conductivity ntawm cov nplaum, thermal conductivity, thiab lwm yam, cov no sawv cev li cas? Ntsib lawv nrog siway hauv qab no!
ROHS yog dab tsi?
ROHS yog tus qauv tsim los ntawm European Union txoj cai, nws lub npe tag nrho yog Cov Lus Qhia rauKev txwv tsis pub muaj phom sij hauv cov khoom siv hluav taws xob thiab hluav taws xob. Tus txheej txheem yuav raug ua tiav thaum Lub Xya Hli 1, 2006, feem ntau yog siv los tswj cov khoom siv thiab cov txheej txheem ntawm cov khoom siv hluav taws xob thiab hluav taws xob, kom nws muaj txiaj ntsig zoo rau tib neeg kev noj qab haus huv thiab kev tiv thaiv ib puag ncig. Lub hom phiaj ntawm tus qauv yog tshem tawm cov hmoov txhuas, mercury, cadmium, hexvalent chromium, polybrominated biphenyls thiab polybrominated biphenyl ethers hauv cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob, thiab tsom rau cov ntsiab lus ntawm cov hlau lead yuav tsum tsis pub tshaj 1%.
NSF yog dab tsi? FDA yog dab tsi? Qhov txawv ntawm lawv yog dab tsi?
1. NSF yog cov lus Askiv luv ntawm National Health Foundation ntawm Tebchaws Meskas, uas yog lub koom haum thib peb uas tsis muaj txiaj ntsig. Nws yog raws li lub teb chaws tus qauv ntawm Teb Chaws Asmeskas, los ntawm kev txhim kho cov qauv, kev sim thiab kev txheeb xyuas, kev tswj xyuas daim ntawv pov thawj thiab cov ntaub ntawv tshawb xyuas, kev kawm thiab kev cob qhia, kev tshawb fawb thiab lwm yam txhais tau tias los xyuas kom meej thiab saib xyuas cov khoom thiab cov thev naus laus zis ntsig txog kev noj qab haus huv thiab ib puag ncig. .
2. Hais txog NSF daim ntawv pov thawj, National Health Foundation (NSF) tsis yog tsoomfwv lub koomhaum, tabsis yog lub koomhaum pabcuam tsis muaj txiaj ntsig. Nws lub hom phiaj yog txhawm rau txhim kho lub neej zoo ntawm pej xeem kev noj qab haus huv. NSF yog tsim los ntawm cov kws paub txog kev noj qab haus huv thiab kev tu cev, suav nrog tsoomfwv cov koomhaum, tsev kawm qib siab, kev lag luam thiab pab pawg neeg siv khoom. Nws txoj haujlwm tsom mus rau kev teeb tsa kev txhim kho thiab kev tswj hwm cov qauv rau txhua yam khoom uas muaj kev cuam tshuam rau kev nyiam huv, kev noj qab haus huv rau pej xeem, thiab lwm yam. NSF muaj lub chaw soj nstuam uas muaj kev ntsuam xyuas tag nrho cov khoom kuaj xyuas kom ua raws li cov qauv tshuaj ntsuam xyuas. Txhua tus tuaj yeem koom nrog cov tuam txhab uas dhau qhov kev tshuaj xyuas NSF tuaj yeem txuas NSF daim ntawv lo rau ntawm cov khoom thiab cov ntaub ntawv hais txog cov khoom kom pom tseeb.
3, NSF cov tuam txhab muaj ntawv pov thawj, uas yog, NSF cov tuam txhab, xws li cov khoom siv hauv tsev, tshuaj, zaub mov, kev noj qab haus huv, kev kawm thiab lwm yam. Cov khoom lag luam muaj feem xyuam nrog cov khoom sib npaug. Lub Chaw Tswj Xyuas Khoom Noj thiab Tshuaj Hauv Tebchaws Meskas (FDA) yog ib lub koom haum ua haujlwm tsim los ntawm tsoomfwv Meskas hauv Lub Tsev Haujlwm Saib Xyuas Kev Noj Qab Haus Huv thiab Tib Neeg (DHHS) thiab Lub Tsev Haujlwm Saib Xyuas Kev Noj Qab Haus Huv (PHS). NSF daim ntawv pov thawj lub cev yog lub koom haum tsis muaj txiaj ntsig thib peb thoob ntiaj teb cov ntawv pov thawj, muaj keeb kwm ntawm 50 xyoo, feem ntau koom nrog kev noj qab haus huv thiab kev nyab xeeb thiab cov qauv kev noj qab haus huv thiab cov ntawv pov thawj cov khoom noj, ntau yam ntawm nws cov qauv kev lag luam tau txais kev hwm thoob ntiaj teb, thiab hauv Tebchaws Meskas yog suav tias yog tus qauv. Nws yog tus qauv kev lag luam muaj cai ntau dua li FDA daim ntawv pov thawj ntawm US Food and Drug Administration.
SGS yog dab tsi? Kev sib raug zoo ntawm SGS thiab ROHS yog dab tsi?
SGS yog cov ntawv luv ntawm Societe Generale de Surveillance SA, txhais ua "General Notary Firm". Founded hauv 1887, nws yog tam sim no lub ntiaj teb loj tshaj plaws thiab qub tshaj plaws ntiag tug thib peb-tog multinational tuam txhab koom nrog cov khoom zoo thiab kev soj ntsuam.Headquartered hauv Geneva, nws muaj 251 ceg thoob ntiaj teb. ROHS yog EU cov lus qhia, SGS tuaj yeem kuaj cov khoom pov thawj thiab cov ntaub ntawv pov thawj raws li ROHS Cov Lus Qhia. Tab sis qhov tseeb, tsis tsuas yog SGS daim ntawv tshaj tawm raug lees paub, muaj lwm lub koom haum kuaj thib peb, xws li ITS thiab lwm yam.
Dab tsi yog thermal conductivity?
Thermal conductivity yog hais txog nyob rau hauv ruaj khov thaum tshav kub kub hloov tej yam kev mob, 1m tuab cov ntaub ntawv, qhov kub thiab txias sib txawv ntawm ob sab ntawm lub nto yog 1 degree (K, ° C), nyob rau hauv 1 teev, los ntawm thaj tsam ntawm 1 square meters ntawm tshav kub hloov, chav tsev. yog watt/meter · degree (W/(m·K), qhov twg K tuaj yeem hloov tau los ntawm ℃).
Thermal conductivity muaj feem xyuam rau cov qauv muaj pes tsawg leeg, ntom, noo noo cov ntsiab lus, kub thiab lwm yam ntawm cov khoom. Cov ntaub ntawv nrog cov qauv amorphou thiab qhov chaw ceev qis muaj tsawg thermal conductivity. Thaum cov ntsiab lus noo noo thiab kub ntawm cov khoom qis, thermal conductivity yog me me.
RTV yog dab tsi?
RTV yog cov ntawv luv ntawm "Room Kub Vulcanized Silicone Rubber" ua lus Askiv, hu ua "chav kub vulcanized silicone roj hmab" lossis "chav kub kho silicone roj hmab", uas yog, cov roj hmab silicone no tuaj yeem kho tau ntawm chav tsev kub (synthetic insulators siab. kub vulcanized silicone roj hmab). RTV antifouling flashover txheej tau dav txais tos los ntawm cov neeg siv hluav taws xob rau nws lub zog tiv thaiv fouling flashover muaj peev xwm, kev saib xyuas tsis pub dawb thiab txheej txheej yooj yim, thiab tau tsim sai heev.
UL yog dab tsi? UL muaj qib dab tsi?
UL yog luv luv rau Underwriter Laboratories Ins. UL Combustion Grade: Flammability Qib UL94 yog tus qauv siv dav dav tshaj plaws rau cov ntaub ntawv yas. Nws yog siv los ntsuas qhov muaj peev xwm ntawm cov khoom siv tuag tom qab raug hluav taws kub. Raws li qhov kub ceev, lub sij hawm kub kub, drip resistance thiab seb qhov poob yog hlawv tuaj yeem muaj ntau txoj kev ntsuas. Ntau qhov txiaj ntsig tuaj yeem tau txais rau txhua yam khoom hauv kev sim nyob ntawm xim lossis tuab. Thaum cov khoom siv ntawm cov khoom raug xaiv, nws qib UL yuav tsum ua kom tau raws li cov nplaim hluav taws kub hnyiab ntawm cov khoom yas los ntawm HB, V-2, V-1 txog V-0: HB: qib nplaim hluav taws kub qis tshaj hauv UL94 tus qauv. Rau cov qauv ntawm 3 mus rau 13 hli tuab, tus nqi combustion yog tsawg dua 40 hli ib feeb; Rau cov qauv tsawg dua 3 hli tuab, qhov kub ntawm qhov tsawg dua 70 hli ib feeb; Los yog tua nyob rau hauv pem hauv ntej ntawm 100 mm kos npe.
V-2: Tom qab ob qhov kev ntsuam xyuas 10-thib ob ntawm cov qauv, cov nplaim hluav taws tuaj yeem tua hauv 60 vib nas this, thiab qee qhov hluav taws kub tuaj yeem poob.
V-1: Tom qab ob qhov kev ntsuam xyuas 10-thib ob ntawm cov qauv, cov nplaim hluav taws tuaj yeem raug tua hauv 60 vib nas this, thiab tsis muaj hluav taws xob tuaj yeem poob.
V-0: Tom qab ob qhov kev ntsuam xyuas 10-thib ob ntawm cov qauv, cov nplaim hluav taws tuaj yeem tua hauv 30 vib nas this, thiab tsis muaj hluav taws xob tuaj yeem poob.
Cov no yog cov ntsiab lus kev paub txog cov nplaum sib koom los ntawm siway, Shanghai Siway Building Materials Co., Limited tau tsim muaj xyoo 1984, Tam sim no, nws muaj ISO9001: 2015 thoob ntiaj teb daim ntawv pov thawj zoo thiab ISO14001 ib puag ncig kev tswj hwm ntawv pov thawj thiab lwm yam ntawv pov thawj.
