Isilinganiso somlilo esingu-1.CM
I-CM okwamanje iyileveli evame ukusetshenziswa kakhulu yokubuyisela ilangabi kukhebula lekhebula.Izinga layo lokuhlola ngu-UL 1581. Ngokwencazelo, inqwaba encane yekhebula lekhebula lekilasi le-Cm izophuma ngokuzenzakalelayo phakathi kwamamitha angu-5 wokusabalaliswa komlilo.
Njengamanje, i-sheath yangaphandle yezintambo zenethiwekhi ye-CM-class yenziwe kakhulu nge-PVC futhi isendlalelo sokufakelwa senziwe nge-PE ephezulu.Uma ishisiwe, izokhipha i-halogen enobuthi, intuthu kanye nokushisa okuningi. Ikhebula le-CM-class ngokuvamile lisetshenziselwa ukusebenza okuvundlile esitezini esisodwa, futhi livame ukutholakala e-United Kingdom, e-Asia nase-Australia.
Isilinganiso somlilo 2.CMR
Ukuphepha kwesilinganiso somlilo we-CMR okwesibili, okutholwa kakhulu ngokuthuthukisa indawo yokuthungela yekhebula ukuze kufezwe injongo yokungashi.Izinga layo lokuhlola ngu-UL 1666. Encazelweni, ngaphansi kwesimo sokushiswa kwefeni ngempoqo, inqwaba yezintambo zenethiwekhi yekhebula ye-CMR kufanele sicishwe phakathi kwamamitha angu-5 wokusabalaliswa komlilo.
Njengamanje, i-sheath yangaphandle yekhebula lenethiwekhi ye-CMR yekilasi lenziwe ngezinto ze-PVC ezingashisi ilangabi, futhi ungqimba lokufakwa kwe-insulation lwenziwe ngezinto eziphakeme kakhulu ze-PE.Ngemuva kokuvutha kwelangabi, lizokhipha igesi enobuthi ene-halogenated (igesi ye-chlorine) kanye nomhwamuko oholayo, ozodla ngokushesha umoya-mpilo osemoyeni futhi wenze ilangabi liphume. I-CMR class cabling isetshenziswa kakhulu ezinhlelweni zokungenisa umoya kumapayipi amakhulu ahlukaniswe ngokomzimba isistimu yekhebula, okungukuthi kusistimu engaphansi yamapayipi aqondile angaphakathi, futhi ivame ukutholakala e-Asia nase-Australia.
3.CMP ukukala umlilo
Isilinganiso somlilo se-CMP siphephe kakhulu.Inokubambezeleka kwelangabi okuphelele futhi ayikhiphi intuthu enobuthi enkulu lapho isha.Izinga lokuhlola le-CMP ngu-UL 910. Ngokwencazelo ye-UL, inqwaba yekhebula le-CMP nezintambo zenethiwekhi kufanele zizicime ngokwazo phakathi kwamamitha angu-5 wokusabalaliswa komlilo ngaphansi komlilo. izimo zokushiswa okunamandla okuphoqelelwe ngabalandeli.
Umgodla wangaphandle wentambo yekhebula yekilasi le-CMP wenziwe nge-fluorine (efana ne-PTFE PTFE, i-FEP e-fluorinated ethylene propylene), enezinga lokushisa eliphezulu lokubola nendawo yokuthungela. nciphisa intuthu nobuthi, ngisho noma kunomlilo, noma esakhiweni kugcwele ukusha okuningi ngenxa yenethiwekhi yekhebula kanye nentuthu noma ubuthi obuyingozi, ngakho-ke ikhebula lenethiwekhi ye-CMP yezinga le-CMP lisetshenziswa embotsheni yokukhipha umoya noma imishini yokubamba umoya esetshenziswayo. i-air circumfluence pressurization system, evamile eCanada nase-United States.
4.I-DongguanWenchangI-Electronic Co., Ltd.ingumkhiqizi waseChina onesitifiketi se-CM, CMR, CMP.
Isigaba se-CMR (ukuhlolwa kokuvutha okuqondile) Lawa amakhebuli ebanga lezentengiso ezingeni le-UL.Izinga lokuphepha lithi UL1666.Akukho ukucaciswa kokuminyana kwentuthu futhi ngokuvamile asetshenziselwa izintambo eziqondile nezivundlile phansi.
Ikilasi le-CMP (I-Stei Sodium Duct Test) ikhebula elidingeka kakhulu kuzinga lokuphepha emlilweni le-UL.Ivamise ukufakwa ezinhlelweni ze-air reflux pressurization ezisetshenziswa emiseleni yokungenisa umoya noma emishinini yokuphatha umoya.Kuvunyelwe eCanada nase-United States.
5. Umehluko phakathi kwe-CM, CMR ne-CMP:
I-CM, i-CMR ne-CMP ziyehluka ngesilinganiso somlilo, isimo sokusha nezinto ezingaphandle zesheath.Ngaphezu kwalokho, zihluka kakhulu ngentengo nendawo yesicelo.
(1)Umehluko enanini.
I-sheath yangaphandle yekhebula le-CM nekhebula le-CMR lenziwe ngezinto ze-PVC, kuyilapho ikhebula le-CMP lenziwe ngezinto ze-fluorine, ngakho intengo yekhebula le-CMP ibiza kakhulu kunekhebula le-CM nentambo ye-CMR.
(2) Umehluko ezindaweni zokufaka izicelo
Ngokuvamile, ikhebula le-CM lisetshenziselwa izintambo ezivundlile zamakheshi ezakhiwo kanye namakamelo aphefumulayo kwezinye izindawo, i-CMR ingasetshenziswa kuzintambo eziqondile zokuphakamisa izakhiwo kanye namaphaseji aqondile, futhi i-CMP ingasetshenziswa ezintambo ezivundlile zamapayipi omoya, aphefumulayo. amakamelo noma ezinye izindawo zokujikeleza komoya.
