1.CM moto mlingo
CM pakali pano ndiye mulingo womwe umagwiritsidwa ntchito kwambiri palawi retardant pa chingwe cha chingwe.Muyezo wake woyeserera ndi UL 1581. Malinga ndi kutanthauzira, kagulu kakang'ono ka chingwe cha Cm-class chidzatuluka mkati mwa 5 metres ya kuyaka.
Pakalipano, chikwama chakunja cha CM-class cable network cables nthawi zambiri chimapangidwa ndi PVC ndipo wosanjikiza wotsekemera amapangidwa ndi PE yochuluka kwambiri.Ikatenthedwa, imatulutsa halogen wapoizoni, utsi ndi kutentha kwambiri.CM-class chingwe chimagwiritsidwa ntchito pothamanga mopingasa pansi pomwe, ndipo nthawi zambiri amapezeka ku United Kingdom, Asia ndi Australia.
2.CMR moto mlingo
Chitetezo cha chiwerengero cha moto cha CMR ndicho chachiwiri, chomwe chimapindula makamaka pokonza malo oyatsira chingwe kuti akwaniritse cholinga chosayaka.Muyezo wake woyesera ndi UL 1666. Mutanthauzo, pansi pa chikhalidwe cha kuyaka kwa mafani okakamizidwa, mtolo wa zingwe za CMR cable network ziyenera kuzimitsidwa mkati mwa mamita 5 kuchokera ku kuyaka kuyaka.
Pakadali pano, chiwombankhanga chakunja cha chingwe cha CMR class network chimapangidwa ndi zinthu za PVC zotchingira moto, ndipo wosanjikizawo amapangidwa ndi zinthu zolimba kwambiri za PE.Pambuyo pa kuyaka kwa lawi lamoto, limatulutsa mpweya woipa wa halogenated (gesi wa chlorine) ndi nthunzi wotsogolera, womwe udzanyeketsa mpweya wa mpweya mumlengalenga ndikupangitsa kuti lawi lamoto lizime. ma cabling system, mwachitsanzo, mkati mwa mains vertical mains subsystem, ndipo amapezeka ku Asia ndi Australia.
3.CMP moto mlingo
Chiwerengero cha moto cha CMP ndichotetezeka kwambiri.Lili ndi mphamvu yowonongeka yamoto ndipo silitulutsa utsi wambiri wapoizoni likayaka. Muyezo wa mayeso a CMP ndi UL 910. Malinga ndi tanthauzo la UL, mtolo wa chingwe cha CMP ndi zingwe za netiweki ziyenera kuzimitsa mkati mwa mamita 5 kuchokera ku kuyaka kufalikira pansi pa mikhalidwe ya kukakamizidwa kwambiri kuyaka ndi mafani.
Chingwe chakunja cha waya wa CMP kalasi chimapangidwa ndi fluorine (monga PTFE PTFE, FEP fluorinated ethylene propylene), yomwe imakhala ndi kutentha kwakukulu komanso kutentha. kuchepetsa utsi ndi poizoni, ngakhale pamene pali moto, kapena m'nyumba mwadzaza kwambiri kuyaka chifukwa chingwe maukonde ndi utsi kapena zoipa poizoni, kotero kalasi CMP chingwe maukonde chingwe ntchito mu mpweya ngalande kapena mpweya potengera zipangizo ntchito. air circumfluence pressurization system, yofala ku Canada ndi United States.
4.DongguanWenchangMalingaliro a kampani Electronic Co., Ltd.ndi wopanga China wokhala ndi CM, CMR, CMP certification.
CMR class (vertical combustion test) Awa ndi zingwe zamakalasi amalonda mulingo wa UL.Muyezo wachitetezo ndi UL1666.Palibe kachulukidwe ka utsi ndipo nthawi zambiri amagwiritsidwa ntchito ngati mawaya olunjika komanso opingasa.
Kalasi ya CMP (Stei Sodium Duct Test) ndiye chingwe chofunikira kwambiri pachitetezo chamoto cha UL.Nthawi zambiri imayikidwa mu air reflux pressurization systems zomwe zimagwiritsidwa ntchito muzitsulo zolowera mpweya kapena zipangizo zothandizira mpweya.Zimavomerezedwa ku Canada ndi United States.
5.Kusiyana pakati pa CM, CMR ndi CMP:
CM, CMR ndi CMP zimasiyana pamlingo wamoto, momwe zimayaka komanso zida zakunja.Kuphatikiza apo, amasiyana kwambiri pamitengo ndi malo ogwiritsira ntchito.
(1) Kusiyana kwa mtengo.
Chingwe chakunja cha CM chingwe ndi chingwe cha CMR chimapangidwa ndi zinthu za PVC, pomwe chingwe cha CMP chimapangidwa ndi zinthu za fluorine, motero mtengo wa chingwe cha CMP ndi wokwera mtengo kwambiri kuposa wa CM chingwe ndi chingwe cha CMR.
(2) Kusiyana kwa madera ogwiritsira ntchito
Nthawi zambiri, chingwe cha CM chimagwiritsidwa ntchito pamawaya opingasa okwera nyumba ndi zipinda zowongoka m'malo ena, CMR itha kugwiritsidwa ntchito pamawiro oyima a zinyalala zomangira ndi ndime zowongoka, ndipo CMP ingagwiritsidwe ntchito pama waya opingasa a ma ducts a mpweya, okwera. zipinda kapena malo ena ozungulira mpweya.
