1.CM mlingo wa moto
Pakadali pano CM ndiye mulingo woletsa moto womwe umagwiritsidwa ntchito kwambiri pa chingwe cha chingwe. Muyezo wake woyeserera ndi UL 1581. Malinga ndi tanthauzo lake, chingwe chaching'ono cha Cm-class chidzazimitsidwa chokha mkati mwa mamita 5 kuchokera pamene kuyaka kwafalikira.
Pakadali pano, chivundikiro chakunja cha zingwe za netiweki ya chingwe cha CM chimapangidwa kwambiri ndi PVC ndipo gawo loteteza kutentha limapangidwa ndi PE yochuluka kwambiri. Ikawotchedwa, imatulutsa halogen yoopsa, utsi ndi kutentha kwambiri. Chingwe cha CM-class nthawi zambiri chimagwiritsidwa ntchito poyendetsa mopingasa pansi imodzi, ndipo chimapezeka kwambiri ku United Kingdom, Asia ndi Australia.
2.CMR moto mlingo
Chitetezo cha CMR fire rating ndi chachiwiri, chomwe chimatheka makamaka pokonza malo oyatsira moto a chingwe kuti chikwaniritse cholinga chake chosayaka. Muyezo wake woyeserera ndi UL 1666. Mu tanthauzo lake, pansi pa kuyaka kwa fan, mtolo wa zingwe za netiweki ya CMR ziyenera kuzimitsidwa mkati mwa mamita 5 kuchokera pamene kuyaka kwafalikira.
Pakadali pano, chivundikiro chakunja cha chingwe cha CMR class cable network chimapangidwa ndi zinthu za PVC zoletsa moto kwambiri, ndipo chotchingiracho chimapangidwa ndi zinthu za PE zolemera kwambiri. Moto ukayaka, umatulutsa mpweya woopsa wa halogenated (mpweya wa chlorine) ndi nthunzi ya lead, zomwe zimadya mpweya wabwino mumlengalenga mwachangu ndikupangitsa moto kuzimitsa. Ma waya a CMR class amagwiritsidwa ntchito kwambiri m'makina opumira mpweya m'makina opatulira omwe ali osiyana ndi makina opatulira, mwachitsanzo m'makina opatulira amkati, ndipo amapezeka kwambiri ku Asia ndi Australia.
3.CMP moto mlingo
Chiyeso cha moto cha CMP ndicho chotetezeka kwambiri. Chimaletsa moto bwino kwambiri ndipo sichitulutsa utsi wambiri woopsa chikayaka. Muyezo wa mayeso a CMP ndi UL 910. Malinga ndi tanthauzo la UL, chingwe cha CMP ndi zingwe za netiweki ziyenera kuzimitsa zokha mkati mwa mamita 5 kuchokera pamene moto wafalikira pansi pa mikhalidwe ya kuyaka mwamphamvu ndi mafani.
Chigoba chakunja cha waya wa CMP chimapangidwa ndi fluorine (monga PTFE PTFE, FEP fluorinated ethylene propylene), yomwe ili ndi kutentha kwakukulu komanso malo oyatsira moto. Chifukwa chingwe cha netiweki ya CMP chingaletse kufalikira kwa kuyaka, chidzatumiza kunja kuti chichepetse utsi ndi poizoni, ngakhale pakakhala moto, ndipo m'nyumbamo mulibe kuyaka kwambiri chifukwa cha netiweki ya netiweki ya chingwe ndi utsi kapena poizoni woopsa, kotero chingwe cha netiweki ya chingwe cha CMP chimagwiritsidwa ntchito mu duct yopumira mpweya kapena zida zogwirira mpweya zomwe zimagwiritsidwa ntchito mu dongosolo la pressurization la mpweya, lodziwika bwino ku Canada ndi United States.
4. DongguanWenchangKampani Yamagetsi, Ltd.ndi wopanga waku China wokhala ndi satifiketi ya CM, CMR, CMP.
Kalasi ya CMR (kuyesa kuyaka koyima) Izi ndi zingwe zamalonda zomwe zili mu muyezo wa UL. Muyezo wachitetezo ndi UL1666. Palibe muyezo wa kuchuluka kwa utsi ndipo nthawi zambiri zimagwiritsidwa ntchito polumikiza pansi moyima ndi mopingasa.
Kalasi ya CMP (Stei Sodium Duct Test) ndiye chingwe chofunikira kwambiri mu muyezo wa chitetezo cha moto wa UL. Nthawi zambiri imayikidwa mu makina opondereza mpweya omwe amagwiritsidwa ntchito mu mapaipi opumira mpweya kapena zida zoyendetsera mpweya. Imavomerezedwa ku Canada ndi United States.
5. Kusiyana pakati pa CM, CMR ndi CMP:
CM, CMR ndi CMP zimasiyana malinga ndi kuchuluka kwa moto, momwe zimayakira komanso momwe zimagwirira ntchito. Kuphatikiza apo, zimasiyana kwambiri malinga ndi mtengo ndi dera lomwe zimagwiritsidwa ntchito.
(1) Kusiyana kwa mtengo.
Chigoba chakunja cha chingwe cha CM ndi chingwe cha CMR chimapangidwa ndi zinthu za PVC, pomwe chingwe cha CMP chimapangidwa ndi zinthu za fluorine, kotero mtengo wa chingwe cha CMP ndi wokwera mtengo kwambiri kuposa wa chingwe cha CM ndi chingwe cha CMR.
(2) Kusiyana kwa madera ogwiritsira ntchito
Kawirikawiri, chingwe cha CM chimagwiritsidwa ntchito polumikiza mawaya opingasa a ma elevator omanga ndi zipinda zopumira mpweya m'malo ena, CMR ingagwiritsidwe ntchito polumikiza mawaya opingasa a ma elevator omanga ndi njira zoyima, ndipo CMP ingagwiritsidwe ntchito polumikiza mawaya opingasa a ma ducts a mpweya, zipinda zopumira mpweya kapena malo ena ozungulira mpweya.
