Isilinganiso somlilo esingu-1.CM
I-CM njengamanje iyizinga elivame ukusetshenziswa kakhulu lokuvimba ilangabi lekhebula lekhebula. Izinga layo lokuhlola yi-UL 1581. Ngokusho kwencazelo, inqwaba encane yekhebula lekhebula le-Cm-class izophuma ngokuzenzakalelayo ngaphakathi kwamamitha ama-5 kusukela ekusakazweni komlilo.
Njengamanje, ingxenye yangaphandle yezintambo zenethiwekhi yekhebula le-CM-class yenziwe kakhulu nge-PVC kanti ungqimba lokuvikela lwenziwe nge-PE enobuthi obukhulu. Uma ishiswa, izokhipha i-halogen enobuthi, intuthu kanye nokushisa okuningi. Ikhebula le-CM-class livame ukusetshenziselwa ukugijima ngokuvundlile esitezi esifanayo, futhi livame ukutholakala e-United Kingdom, e-Asia nase-Australia.
Isilinganiso somlilo se-CMR 2.
Ukuphepha kwesilinganiso somlilo se-CMR sesibili, okufezwa kakhulu ngokuthuthukisa indawo yokushisa yekhebula ukuze kufezwe injongo yokungashi. Izinga layo lokuhlola yi-UL 1666. Encazelweni, ngaphansi kwesimo sokushiswa kwabalandeli ngenkani, inqwaba yezintambo zenethiwekhi yekhebula le-CMR kumele icinywe ngaphakathi kwamamitha ama-5 kusukela ekusakazweni komlilo.
Njengamanje, igobolondo langaphandle lekhebula lenethiwekhi yekhebula lekilasi le-CMR lenziwe ngezinto ze-PVC ezigcina ilangabi kakhulu, kanti ungqimba lokuvikela lwenziwe ngezinto ze-PE ezixinene kakhulu. Ngemva kokusha kwelangabi, lizokhipha igesi enobuthi ene-halogenated (igesi ye-chlorine) kanye nomhwamuko we-lead, okuzodla umoya-mpilo emoyeni ngokushesha futhi kwenze ilangabi licime. Ikhebula lekilasi le-CMR lisetshenziswa kabanzi ezinhlelweni zokungenisa umoya ezindaweni ezinkulu ezihlukaniswe ngokomzimba ohlelweni lwekhebula, okungukuthi ohlelweni olungaphansi lwezintambo ezinkulu eziqondile zangaphakathi, futhi livame ukutholakala e-Asia nase-Australia.
Isilinganiso somlilo se-CMP esingu-3.
Isilinganiso somlilo se-CMP yisona esiphephe kakhulu. Sine-flame retardancy ephelele futhi asikhiphi intuthu enobuthi eningi lapho sivutha. Izinga lokuhlolwa kwe-CMP yi-UL 910. Ngokusho kwencazelo ye-UL, inqwaba yezintambo ze-CMP kanye nezintambo zenethiwekhi kumele zizicime ngaphakathi kwamamitha ama-5 kusukela ekusakazweni komlilo ngaphansi kwezimo zokushisa okuphoqelelwe ngabalandeli.
Igobolondo langaphandle lentambo yekhebula yekilasi le-CMP lenziwe nge-fluorine (njenge-PTFE PTFE, i-FEP fluorinated ethylene propylene), enokushisa okuphezulu kokubola kanye nendawo yokushisa. Ngoba intambo yenethiwekhi yekhebula le-CMP ingamisa ukusabalala kokusha, izothumela ngaphandle ukunciphisa intuthu kanye nobuthi, noma ngabe kukhona umlilo, noma ngabe isakhiwo sigcwele ukusha okuningi ngenxa yenethiwekhi yekhebula kanye nentuthu noma ubuthi obuyingozi, ngakho-ke intambo yenethiwekhi yekhebula le-CMP yebanga eliphakathi isetshenziswa epayipini lokungenisa umoya noma imishini yokuphatha umoya esetshenziswa ohlelweni lokucindezela umoya olujikelezayo, oluvame eCanada nase-United States.
4. I-DongguanI-WenchangI-Electronic Co., Ltd.ungumkhiqizi waseShayina onesitifiketi se-CM, CMR, kanye ne-CMP.
Isigaba se-CMR (ukuhlolwa kokushisa okuqondile) Lezi yizintambo zezinga lokuhweba ezisezingeni le-UL. Izinga lokuphepha yi-UL1666. Akukho ncazelo yobuningi bentuthu futhi ngokuvamile zisetshenziselwa izintambo eziqondile nezivundlile phansi.
Ikilasi le-CMP (Stei Sodium Duct Test) yikhebula elidingeka kakhulu ezindinganisweni zokuphepha komlilo ze-UL. Ngokuvamile lifakwa ezinhlelweni zokucindezela umoya ezisetshenziswa emigudwini yokungenisa umoya noma emishinini yokuphatha umoya. Livunyiwe eCanada nase-United States.
5. Umehluko phakathi kwe-CM, i-CMR kanye ne-CMP:
I-CM, i-CMR kanye ne-CMP ziyahlukahluka ngesilinganiso somlilo, isimo sokusha kanye nezinto zomgodla wangaphandle. Ngaphezu kwalokho, ziyahlukahluka kakhulu ngentengo nendawo yokusetshenziswa.
(1) Umehluko ngentengo.
Igobolondo langaphandle lekhebula le-CM kanye nekhebula le-CMR lenziwe ngezinto ze-PVC, kuyilapho ikhebula le-CMP lenziwe ngezinto ze-fluorine, ngakho-ke intengo yekhebula le-CMP ibiza kakhulu kunekhebula le-CM kanye nekhebula le-CMR.
(2) Umehluko ezindaweni zokusetshenziswa
Ngokuvamile, ikhebula le-CM lisetshenziswa ekuxhumaneni okuvundlile kwama-lift ezakhiwo kanye namakamelo afuthwayo kwezinye izindawo, i-CMR ingasetshenziswa ekuxhumaneni okuvundlile kwama-lift ezakhiwo kanye nezindlela ezivundlile, kanti i-CMP ingasetshenziswa ekuxhumaneni okuvundlile kwama-air ducts, amakamelo afuthwayo noma ezinye izindawo zokujikeleza komoya.
