Txawm peb xav tsim cov nplaum lossis yuav cov nplaum, peb feem ntau pom tias qee cov nplaum yuav muaj daim ntawv pov thawj ROHS, daim ntawv pov thawj NFS, nrog rau cov thermal conductivity ntawm cov nplaum, thermal conductivity, thiab lwm yam, cov no sawv cev rau dab tsi? Ntsib lawv nrog siway hauv qab no!
ROHS yog dab tsi?
ROHS yog tus qauv yuav tsum tau ua los ntawm European Union txoj cai lij choj, nws lub npe tag nrho yog Directive on theKev Txwv Cov Khoom Phom Sij hauv cov khoom siv hluav taws xob thiab hluav taws xob. Tus qauv yuav raug siv rau 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, yog li nws zoo dua 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 hlau lead, mercury, cadmium, hexvalent chromium, polybrominated biphenyls thiab polybrominated biphenyl ethers hauv cov khoom siv cav thiab hluav taws xob, thiab tsom mus 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 lus Askiv luv ntawm Lub Koom Haum Kev Noj Qab Haus Huv Hauv Tebchaws Meskas, uas yog ib lub koom haum tsis muaj txiaj ntsig thib peb. Nws yog raws li cov qauv hauv tebchaws Meskas, los ntawm kev tsim cov qauv, kev sim thiab kev txheeb xyuas, kev tswj hwm daim ntawv pov thawj thiab cov ntaub ntawv tshuaj xyuas, kev kawm thiab kev cob qhia, kev tshawb fawb thiab lwm txoj hauv kev los xyuas kom meej thiab saib xyuas cov khoom thiab cov thev naus laus zis ntsig txog kev noj qab haus huv pej xeem thiab ib puag ncig.
2. Hais txog daim ntawv pov thawj NSF, Lub Koom Haum Kev Noj Qab Haus Huv Hauv Tebchaws (NSF) tsis yog ib lub koom haum tsoomfwv, tab sis yog ib lub koom haum pabcuam ntiag tug uas tsis muaj txiaj ntsig. Nws lub hom phiaj yog los txhim kho lub neej zoo ntawm kev noj qab haus huv pej xeem. NSF muaj cov kws tshaj lij kev noj qab haus huv pej xeem thiab kev tu cev, suav nrog cov koom haum tsoomfwv, tsev kawm qib siab, kev lag luam thiab cov neeg siv khoom. Nws txoj haujlwm tsom mus rau kev teeb tsa cov qauv kev txhim kho thiab kev tswj hwm rau txhua yam khoom uas muaj feem cuam tshuam rau kev tu cev, kev noj qab haus huv pej xeem, thiab lwm yam. NSF muaj lub chaw soj nstuam dav dav uas kuaj txhua yam khoom uas tau sim rau kev ua raws li cov qauv kev tshuaj xyuas. Txhua tus neeg tsim khoom koom nrog uas dhau qhov kev tshuaj xyuas NSF tuaj yeem txuas daim ntawv lo NSF rau ntawm cov khoom thiab cov ntaub ntawv hais txog cov khoom los qhia kev ntseeg siab.
3, cov tuam txhab uas tau ntawv pov thawj los ntawm NSF, uas yog, cov tuam txhab NSF, xws li cov khoom siv hauv tsev, tshuaj, khoom noj, kev noj qab haus huv, kev kawm thiab lwm yam. Cov khoom muaj feem cuam tshuam nrog pawg sib npaug. Lub Koom Haum Saib Xyuas Khoom Noj thiab Tshuaj ntawm Tebchaws Meskas (FDA) yog ib lub koom haum ua haujlwm uas tau tsim los ntawm tsoomfwv Meskas hauv Lub Tsev Haujlwm Saib Xyuas Kev Noj Qab Haus Huv thiab Kev Pabcuam Tib Neeg (DHHS) thiab Lub Tsev Haujlwm Saib Xyuas Kev Noj Qab Haus Huv Pej Xeem (PHS). Lub koom haum pov thawj NSF yog lub koom haum pov thawj thoob ntiaj teb uas tsis yog koom haum ua lag luam, muaj keeb kwm 50 xyoo, feem ntau koom nrog kev noj qab haus huv pej xeem thiab kev nyab xeeb thiab kev noj qab haus huv thiab kev ua haujlwm pov thawj khoom noj, ntau yam ntawm nws cov qauv kev lag luam tau txais kev hwm dav hauv ntiaj teb, thiab hauv Tebchaws Meskas yog suav tias yog tus qauv. Nws yog tus qauv kev lag luam muaj cai ntau dua li daim ntawv pov thawj FDA ntawm Lub Koom Haum Saib Xyuas Khoom Noj thiab Tshuaj ntawm Tebchaws Meskas.
SGS yog dab tsi? Kev sib raug zoo ntawm SGS thiab ROHS yog dab tsi?
SGS yog lub npe luv ntawm Societe Generale de Surveillance SA, txhais ua "General Notary Firm". Tau tsim muaj xyoo 1887, tam sim no nws yog lub tuam txhab loj tshaj plaws thiab qub tshaj plaws hauv ntiaj teb uas koom nrog kev tsim khoom zoo thiab kev ntsuam xyuas kev siv tshuab. Lub hauv paus chaw ua haujlwm nyob hauv Geneva, nws muaj 251 ceg thoob ntiaj teb. ROHS yog EU cov lus qhia, SGS tuaj yeem ua daim ntawv pov thawj khoom kuaj thiab daim ntawv pov thawj system raws li ROHS Directive. Tab sis qhov tseeb, tsis yog tsuas yog daim ntawv qhia SGS raug lees paub xwb, tab sis kuj muaj lwm lub koom haum kuaj thib peb, xws li ITS thiab lwm yam.
Cov thermal conductivity yog dab tsi?
Thermal conductivity yog hais txog qhov ruaj khov ntawm cov cua sov hloov pauv, cov khoom siv tuab 1m, qhov sib txawv ntawm qhov kub ntawm ob sab ntawm qhov chaw yog 1 degree (K, ° C), hauv 1 teev, los ntawm thaj tsam ntawm 1 square meters ntawm cua sov hloov pauv, chav tsev yog watt / meter · degree (W / (m · K), qhov twg K tuaj yeem hloov los ntawm ℃).
Kev ua kom sov ntawm cov khoom muaj feem cuam tshuam nrog cov qauv sib xyaw, qhov ceev, cov dej noo, qhov kub thiab lwm yam ntawm cov khoom. Cov khoom uas muaj cov qauv amorphous thiab qhov ceev qis muaj cov thermal conductivity qis. Thaum cov dej noo thiab qhov kub ntawm cov khoom qis, cov thermal conductivity me me.
RTV yog dab tsi?
RTV yog lub npe luv ntawm "Room Temperature Vulcanized Silicone Rubber" hauv lus Askiv, hu ua "room temperature vulcanized silicone rubber" lossis "room temperature cured silicone rubber", uas yog, cov roj hmab silicone no tuaj yeem kho tau ntawm qhov kub thiab txias hauv chav (cov insulators hluavtaws yog cov roj hmab silicone kub vulcanized). RTV antifouling flashover coating tau txais tos los ntawm cov neeg siv hluav taws xob vim nws muaj peev xwm tiv thaiv kev kub hnyiab, tsis tas yuav saib xyuas thiab yooj yim txheej txheem, thiab tau tsim kho sai.
UL yog dab tsi? UL muaj cov qib twg?
UL luv rau Underwriter Laboratories Ins. UL Qib Kev Sib Tsoo: Kev Kub Ntxhov Qib UL94 yog tus qauv kev kub ntxhov siv dav tshaj plaws rau cov khoom siv yas. Nws yog siv los ntsuas qhov muaj peev xwm ntawm cov khoom kom tuag tom qab raug hluav taws. Raws li qhov ceev ntawm kev kub hnyiab, lub sijhawm kub hnyiab, kev tiv thaiv dej ntws thiab seb qhov poob puas kub hnyiab tuaj yeem muaj ntau txoj kev ntsuam xyuas. Ntau tus nqi tuaj yeem tau txais rau txhua yam khoom siv hauv kev sim nyob ntawm xim lossis tuab. Thaum xaiv cov khoom siv ntawm cov khoom, nws qib UL yuav tsum ua tau raws li qib hluav taws kub ntawm cov khoom yas los ntawm HB, V-2, V-1 txog V-0: HB: qib hluav taws kub qis tshaj plaws hauv tus qauv UL94. Rau cov qauv 3 txog 13 hli tuab, qhov nrawm ntawm kev kub hnyiab tsawg dua 40 hli ib feeb; Rau cov qauv tsawg dua 3 hli tuab, qhov nrawm ntawm kev kub hnyiab tsawg dua 70 hli ib feeb; Lossis tua hluav taws ua ntej ntawm lub cim 100 hli.
V-2: Tom qab ob qhov kev sim hluav taws kub 10-thib ob ntawm cov qauv, lub nplaim taws tuaj yeem tua tau hauv 60 vib nas this, thiab qee cov khoom hluav taws kub tuaj yeem poob.
V-1: Tom qab ob qhov kev sim hluav taws kub 10-thib ob ntawm cov qauv, lub nplaim taws tuaj yeem tua tau hauv 60 vib nas this, thiab tsis muaj cov khoom kub hnyiab poob tau.
V-0: Tom qab ob qhov kev sim hluav taws kub 10-thib ob ntawm cov qauv, lub nplaim taws tuaj yeem tua tau hauv 30 vib nas this, thiab tsis muaj cov khoom kub hnyiab poob tau.
Cov no yog cov ntsiab lus paub txog cov nplaum uas siway tau qhia, Shanghai Siway Building Materials Co., Limited tau tsim muaj xyoo 1984, Tam sim no, nws muaj daim ntawv pov thawj zoo thoob ntiaj teb ISO9001: 2015 thiab daim ntawv pov thawj tswj hwm ib puag ncig ISO14001 thiab lwm yam ntawv pov thawj.
