1.CM qhov ntsuas hluav taws
CM tam sim no yog qib hluav taws kub tshaj plaws rau cable cable. Nws tus qauv xeem yog UL 1581. Raws li qhov kev txhais, ib pob me me ntawm Cm-class cable cable yuav cia li tawm mus hauv 5 meters ntawm kev sib kis hluav taws.
Tam sim no, lub plhaub sab nraud ntawm CM-chav kawm cable network cables feem ntau yog ua los ntawm PVC thiab cov txheej rwb thaiv tsev yog ua los ntawm high-density PE. Thaum hlawv, nws yuav tso tawm cov tshuaj lom halogen, pa luam yeeb thiab ntau cua sov. CM-chav kawm cable feem ntau yog siv rau kev khiav kab rov tav ntawm tib lub plag tsev, thiab feem ntau pom muaj nyob rau hauv United Kingdom, Asia thiab Australia.
2. Kev ntsuas hluav taws CMR
Kev nyab xeeb ntawm CMR qhov ntsuas hluav taws yog qhov thib ob, uas feem ntau yog ua tiav los ntawm kev txhim kho qhov chaw hluav taws xob ntawm lub cable kom ua tiav lub hom phiaj ntawm tsis kub hnyiab. Nws tus qauv xeem yog UL 1666. Hauv kev txhais, nyob rau hauv qhov xwm txheej ntawm kev yuam kom kiv cua hlawv, ib pob ntawm CMR cable network cables yuav tsum tau tua hluav taws hauv 5 meters ntawm qhov sib kis hluav taws.
Tam sim no, lub plhaub sab nraud ntawm CMR chav kawm cable network cable yog ua los ntawm cov khoom siv PVC uas tiv taus hluav taws kub, thiab cov txheej rwb thaiv tsev yog ua los ntawm cov khoom siv PE uas muaj qhov ntom ntom siab. Tom qab hluav taws kub hnyiab, nws yuav tso tawm cov pa roj halogenated lom (cov roj chlorine) thiab cov pa ua pa, uas yuav sai sai noj cov pa oxygen hauv huab cua thiab ua rau hluav taws kub tawm mus. CMR chav kawm cabling yog siv dav hauv cov tshuab cua hauv cov kav dej loj uas tau sib cais los ntawm lub cev cabling, piv txwv li hauv cov kab ke sab hauv ntsug, thiab feem ntau pom muaj nyob hauv Asia thiab Australia.
3. Kev ntsuas hluav taws CMP
Qhov ntsuas hluav taws CMP yog qhov muaj kev nyab xeeb tshaj plaws. Nws muaj kev tiv thaiv hluav taws zoo meej thiab tsis tso pa luam yeeb ntau thaum hlawv. Tus qauv xeem CMP yog UL 910. Raws li UL txhais, ib pob ntawm CMP cable thiab network cables yuav tsum tua lawv tus kheej hauv 5 meters ntawm qhov sib kis ntawm kev sib kis hauv qab cov xwm txheej ntawm kev yuam kom hlawv los ntawm cov kiv cua.
Lub plhaub sab nraud ntawm CMP chav kawm cable hlau yog ua los ntawm fluorine (xws li PTFE PTFE, FEP fluorinated ethylene propylene), uas muaj qhov kub thiab txias siab thiab qhov chaw hluav taws xob. Vim tias CMP cable network cable tuaj yeem tiv thaiv kev sib kis ntawm kev sib txuas, yuav xa tawm los txo cov pa luam yeeb thiab cov tshuaj lom, txawm tias thaum muaj hluav taws, thiab tsis muaj kev kub hnyiab ntau hauv lub tsev vim yog cable network thiab cov pa luam yeeb lossis cov tshuaj lom, yog li qib CMP cable network cable yog siv rau hauv cov kav dej cua lossis cov khoom siv tswj cua siv cov cua circumfluence pressurization system, feem ntau hauv Canada thiab Tebchaws Meskas.
4.DongguanWenchangTuam Txhab Hluav Taws Xob, Ltd.yog lub chaw tsim khoom hauv Suav teb nrog CM, CMR, CMP daim ntawv pov thawj.
Chav kawm CMR (kev sim hluav taws ntsug) Cov no yog cov xov hluav taws xob qib lag luam hauv tus qauv UL. Tus qauv kev nyab xeeb yog UL1666. Tsis muaj cov lus qhia txog pa luam yeeb thiab feem ntau lawv siv rau kev sib txuas hauv pem teb ntsug thiab kab rov tav.
Chav kawm CMP (Stei Sodium Duct Test) yog qhov cable uas xav tau tshaj plaws hauv UL tus qauv kev nyab xeeb hluav taws. Nws feem ntau yog ntsia rau hauv cov tshuab cua reflux pressurization siv rau hauv cov kav dej cua lossis cov khoom siv tswj cua. Nws tau pom zoo hauv Canada thiab Tebchaws Meskas.
5. Qhov sib txawv ntawm CM, CMR thiab CMP:
CM, CMR thiab CMP sib txawv ntawm qib hluav taws, qhov xwm txheej kub hnyiab thiab cov khoom siv sab nraud. Tsis tas li ntawd xwb, lawv sib txawv heev ntawm tus nqi thiab thaj chaw siv.
(1) Qhov sib txawv ntawm tus nqi.
Lub plhaub sab nraud ntawm CM cable thiab CMR cable yog ua los ntawm cov khoom siv PVC, thaum CMP cable yog ua los ntawm cov khoom siv fluorine, yog li tus nqi ntawm CMP cable kim dua li ntawm CM cable thiab CMR cable.
(2) Qhov sib txawv ntawm thaj chaw thov
Feem ntau, CM cable siv rau hauv cov xov hluav taws xob kab rov tav ntawm cov tsev nqa thiab cov chav inflatable hauv lwm qhov chaw, CMR tuaj yeem siv rau hauv cov xov hluav taws xob ntsug ntawm cov tsev nqa thiab cov kev hla ntsug, thiab CMP tuaj yeem siv rau hauv cov xov hluav taws xob kab rov tav ntawm cov pa cua, cov chav inflatable lossis lwm qhov chaw ncig cua.
