Uvavanyo lomlilo lwe-1.CM
I-CM okwangoku yeyona nqanaba lisetyenziswa kakhulu ekuthinteleni ilangatye kwintambo yentambo. Umgangatho wayo wovavanyo yi-UL 1581. Ngokwenkcazo, inqwaba encinci yentambo yentambo yeklasi ye-Cm iya kuzicima ngokuzenzekelayo kwiimitha ezi-5 emva kokusasazwa komlilo.
Okwangoku, i-sheath yangaphandle yeentambo zenethiwekhi yekhebula le-CM-class yenziwe kakhulu nge-PVC kwaye umaleko wokukhusela wenziwe nge-PE enobunzima obuphezulu. Xa itshisiwe, iya kukhupha i-halogen enobuthi, umsi kunye nobushushu obuninzi. Intambo yeklasi ye-CM isetyenziselwa ukubaleka ngokuthe tye kumgangatho omnye, kwaye ixhaphake kakhulu e-United Kingdom, e-Asia nase-Australia.
2. Uvavanyo lomlilo lweCMR
Ukhuseleko lomlinganiselo womlilo we-CMR lolwesibini, olufezekiswa ikakhulu ngokuphucula indawo yokutsha kwentambo ukuze kufezekiswe injongo yokungatsha. Umgangatho wayo wovavanyo yi-UL 1666. Kwinkcazo, phantsi kwemeko yokutsha ngenkani kwefeni, inqwaba yeentambo zenethiwekhi yentambo ye-CMR kufuneka icinywe ngaphakathi kweemitha ezi-5 ukusuka ekusasazekeni kokutsha.
Okwangoku, i-sheath yangaphandle yentambo yenethiwekhi yekhebula le-CMR yenziwe ngezinto ze-PVC ezithintela ilangatye kakhulu, kwaye umaleko wokufakelwa wenziwe ngezinto ze-PE ezinobunzima obuphezulu. Emva kokutsha kwedangatye, iya kukhupha igesi ene-halogenated enobuthi (igesi ye-chlorine) kunye nomphunga we-lead, oya kudla ngokukhawuleza ioksijini emoyeni kwaye wenze ilangatye licime. Iintambo zeklasi ze-CMR zisetyenziswa kakhulu kwiinkqubo zokungenisa umoya kwiindawo eziphambili ezahlulwe ngokwasemzimbeni kwinkqubo yeentambo, oko kukuthi, kwinkqubo ephantsi ye-mains ethe nkqo yangaphakathi, kwaye ifumaneka kakhulu e-Asia nase-Australia.
3.CMP umlinganiselo womlilo
Uvavanyo lomlilo lwe-CMP lolona lukhuselekileyo. Lune-flame retardancy egqibeleleyo kwaye alukhuphi umsi onetyhefu omninzi xa utsha. Umgangatho wovavanyo lwe-CMP yi-UL 910. Ngokwenkcazo ye-UL, inqwaba yeentambo ze-CMP kunye neentambo zenethiwekhi kufuneka zizicime ngaphakathi kweemitha ezi-5 ukusuka ekutsha phantsi kweemeko zokutsha okunyanzelisiweyo ngabalandeli.
Ingxolo yangaphandle yentambo yekhebula yeklasi ye-CMP yenziwe nge-fluorine (efana ne-PTFE PTFE, i-FEP fluorinated ethylene propylene), enobushushu obuphezulu bokubola kunye nendawo yokutsha. Ngenxa yokuba intambo yenethiwekhi yekhebula ye-CMP inokumisa ukusasazeka kokutsha, iya kuthumela ngaphandle ukunciphisa umsi kunye netyhefu, nokuba kukho umlilo, kwaye kwisakhiwo kugcwele ukutsha okuninzi ngenxa yenethiwekhi yekhebula kunye nomsi okanye iityhefu eziyingozi, ngoko ke intambo yenethiwekhi yekhebula ye-CMP yeklasi isetyenziswa kwi-ventilation duct okanye izixhobo zokuphatha umoya ezisetyenzisiweyo kwinkqubo yoxinzelelo lomoya, exhaphakileyo eKhanada nase-United States.
4.DongguanIWenchangI-Electronic Co., Ltd.ngumvelisi waseTshayina onesiqinisekiso seCM, CMR, CMP.
Udidi lwe-CMR (uvavanyo lokutsha oluthe nkqo) Ezi ziintambo zodidi lwezorhwebo kumgangatho we-UL. Umgangatho wokhuseleko yi-UL1666. Akukho nkcazo yoxinano lomsi kwaye zihlala zisetyenziselwa ukufakelwa kweentambo ezithe nkqo phantsi kunye nezithe tye.
Udidi lwe-CMP (Stei Sodium Duct Test) yeyona ntambo ifunekayo kakhulu kumgangatho wokhuseleko lomlilo we-UL. Idla ngokufakwa kwiinkqubo zoxinzelelo lomoya oluvuselelayo ezisetyenziswa kwiipayipi zomoya okanye kwizixhobo zokuphatha umoya. Ivunyiwe eKhanada nase-United States.
5. Umahluko phakathi kwe-CM, i-CMR kunye ne-CMP:
I-CM, i-CMR kunye ne-CMP zahlukile ngokwezinga lomlilo, imeko yokutsha kunye nezinto ezingaphandle kwesigqubuthelo. Ukongeza, zahluke kakhulu ngokwexabiso kunye nendawo yokusetyenziswa.
(1) Umahluko kwixabiso.
I-sheath yangaphandle yekhebula le-CM kunye nekhebula le-CMR yenziwe ngezinto ze-PVC, ngelixa ikhebula le-CMP lenziwe ngezinto ze-fluorine, ngoko ke ixabiso lekhebula le-CMP libiza kakhulu kunelekhebula le-CM kunye nekhebula le-CMR.
(2) Umahluko kwiindawo ezisetyenziswayo
Ngokubanzi, intambo yeCM isetyenziswa kwiintambo ezithe tye zezakhiwo eziphakamisayo kunye namagumbi anokuphefumla kwezinye iindawo, iCMR ingasetyenziswa kwiintambo ezithe nkqo zezakhiwo eziphakamisayo kunye neendlela ezithe nkqo, kwaye iCMP ingasetyenziswa kwiintambo ezithe nkqo zemibhobho yomoya, amagumbi anokuphefumla okanye ezinye iindawo zokujikeleza komoya.
