Umqondo Wesilinganiso Sokubuyiswa Kwelangabi

Ukuhlolwa kwesilinganiso sokubuyiswa komlilo kuyindlela esetshenziselwa ukuhlola ikhono lento ebonakalayo yokumelana nokusabalala kwelangabi. Amazinga ajwayelekile afaka i-UL94, IEC 60695-11-10, kanye ne-GB/T 5169.16. Ku-UL94 ejwayelekile,Ukuhlola Ukuvutha Kwezinto Zepulasitiki Zezingxenye Zamadivayisi Nezisetshenziswa, izilinganiso ze-flame retardant zihlukaniswa zibe amazinga angu-12 ngokusekelwe kukuqina kokuhlolwa nokusebenza: HB, V-2, V-1, V-0, 5VA, 5VB, VTM-0, VTM-1, VTM-2, HBF, HF1, ne-HF2.

Ngokuvamile, izilinganiso ezivame ukusetshenziswa zokubuyiswa kwelangabi zisukela ku-V-0 kuye ku-V-2, ne-V-0 ebonisa ukusebenza okuhle kakhulu kwe-flame retardant.

1.1 Izincazelo Zezilinganiso Ezine Zokubuyiswa Komlilo

I-HB (Ukushiswa Okuvundlile):
Isilinganiso se-HB sibonisa ukuthi impahla isha kancane kodwa ayizicishi ngokwayo. Izinga eliphansi kakhulu ku-UL94 futhi livame ukusetshenziswa lapho izindlela zokuhlola eziqondile (V-0, V-1, noma V-2) zingasebenzi.

I-V-2 (Ukushiswa Okuqondile - Ileveli 2):
Isilinganiso se-V-2 sisho ukuthi okokusebenza kuthola izivivinyo ezimbili zelangabi eziqondile ezingamasekhondi ayi-10. Ngemva kokuba ilangabi lisusiwe, isikhathi sokushiswa kwempahla asidluli imizuzwana engu-30, futhi ingase ithungele ukotini obekwe 30 cm ngaphansi. Nokho, ilangabi akufanele lisabalale ngaphezu komugqa omakiwe.

I-V-1 (Ukushiswa Okuqondile - Ileveli 1):
Isilinganiso se-V-1 sisho ukuthi okokusebenza kuthola izivivinyo ezimbili zelangabi eziqondile ezingamasekhondi ayi-10. Ngemuva kokuthi ilangabi lisusiwe, isikhathi sokushiswa kwempahla asidluli imizuzwana engu-30, futhi ilangabi akufanele lisabalale ngaphezu komugqa omakiwe noma lithungele ukotini obekwe ngamasentimitha angama-30 ngaphansi.

I-V-0 (Ukushiswa Okuqondile - Ileveli 0):
Isilinganiso se-V-0 sisho ukuthi okokusebenza kuthola izivivinyo ezimbili zelangabi eziqondile ezingamasekhondi ayi-10. Ngemva kokuba ilangabi lisusiwe, isikhathi sokushiswa kwempahla asidluli imizuzwana engu-10, futhi ilangabi akufanele lisabalale ngaphezu komugqa omakiwe noma lithungele ukotini obekwe ngaphansi kuka-30 cm.

1.2 Isingeniso Kwezinye Izilinganiso Zokubuyiswa Kwelangabi

I-5VA ne-5VB ingeyesigaba sokuhlolwa kokuvutha okuqondile kusetshenziswa ilangabi lokuhlola elingu-500W (ubude belangabi elingu-125mm).

I-5VA (I-Vertical Burning – 5VA Level):
Isilinganiso se-5VA siyingxenye yezinga le-UL94. Kubonisa ukuthi ngemva kokukhishwa kwelangabi, isikhathi sokushiswa kwempahla asidluli imizuzwana engama-60, ilangabi akufanele lisabalale ngaphezu komugqa omakiwe, futhi noma imaphi amalangabi aconsayo akumele adlule imizuzwana engama-60.

I-5VB (I-Vertical Burning – 5VB Level):
Isilinganiso se-5VB siyefana ne-5VA, sinemibandela efanayo yokushiswa kwesikhathi nokusabalala komlilo.

I-VTM-0, VTM-1, VTM-2 izigaba zezinto ezizacile (ubukhulu obungu-< 0.025mm) ekuhlolweni kokuvutha okuqondile (ubude belangabi obungama-20mm), obusebenza kumafilimu epulasitiki.

I-VTM-0 (I-Vertical Tray Burning – Level 0):
Isilinganiso se-VTM-0 sisho ukuthi ngemva kokususwa komlilo, isikhathi sokushiswa kwempahla asidluli imizuzwana eyi-10, futhi ilangabi akufanele lisabalale ngaphezu komugqa omakiwe.

I-VTM-1 (I-Vertical Tray Burning – Level 1):
Isilinganiso se-VTM-1 sisho ukuthi ngemva kokususwa komlilo, isikhathi sokushiswa kwempahla asidluli imizuzwana engu-30, futhi ilangabi akufanele lisabalale ngaphezu komugqa omakiwe.

I-VTM-2 (I-Vertical Tray Burning – Level 2):
Isilinganiso se-VTM-2 sinemibandela efanayo neye-VTM-1.

I-HBF, i-HF1, i-HF2 izigaba zokuhlolwa kokushiswa okuvundlile ezintweni ezinegwebu (38mm ukuphakama kwelangabi).

I-HBF (Indawo Evundlile Evuthayo Enegwebu):
Isilinganiso se-HBF sisho ukuthi isivinini sokushiswa kwezinto ezinegwebu asidluli ku-40 mm/min, futhi ilangabi kufanele licime ngaphambi kokufinyelela kulayini omakiwe ongu-125mm.

I-HF-1 (Ukushiswa Okuvundlile – Ileveli 1):
Isilinganiso se-HF-1 sisho ukuthi ngemva kokususwa komlilo, isikhathi sokushiswa kwempahla asidluli amasekhondi angu-5, futhi ilangabi akufanele lisabalale ngaphezu komugqa omakiwe.

I-HF-2 (Ukushiswa Okuvundlile – Ileveli 2):
Isilinganiso se-HF-2 sisho ukuthi ngemva kokususwa komlilo, isikhathi sokushiswa kwempahla asidluli amasekhondi angu-10, futhi ilangabi akufanele lisabalale ngaphezu komugqa omakiwe.

Inhloso Yokuhlolwa Kwesilinganiso Se-Flame Retardant

Izinjongo zokuhlolwa kokulinganisa i-flame retardant zifaka:

2.1 Ukuhlola Ukusebenza Kokushiswa Kwempahla

Ukunquma isivinini sokushiswa kwento ethile, ukusabalala kwelangabi, nokubhebhetheka komlilo ngaphansi kwezimo zomlilo kusiza ukuhlola ukuphepha kwayo, ukwethembeka, nokufaneleka kwezinhlelo zokusebenza ezimelana nomlilo.

2.2 Ukunquma Amandla Okubuyisela Ilangabi

Ukuhlola kuhlonza amandla okwenza okuthile okucindezela ukusakazeka kwelangabi lapho kuvezwe kumthombo womlilo, okubalulekile ekuvimbeleni ukukhuphuka komlilo kanye nokunciphisa umonakalo.

2.3 Ukukhetha Nokusetshenziswa Kwempahla Eqondisayo

Ngokuqhathanisa izakhiwo ezivimbela amalangabi ezinto ezihlukene, izinsiza zokuhlola ekukhetheni izinto ezifanele zokwakha, ezokuthutha, ezogesi, nezinye izinkambu ukuze kuthuthukiswe ukuphepha emlilweni.

2.4 Ukuhambisana Nemithethonqubo Namazinga

Ukuhlolwa kwe-flame retardant kuvame ukwenziwa ngokuya ngemithetho kazwelonke noma yemboni. Iqinisekisa ukuthi izinto ezisetshenziswayo zihlangabezana nezidingo zokuphepha nokuhambisana nezicelo ezithile.

Kafushane, ukuhlolwa kokulinganisa kokunciphisa ilangabi kunikeza idatha ebalulekile yokukhethwa kwezinto ezibonakalayo, ukuthuthukiswa kokuphepha komlilo, nokuhambisana nomthetho ngokuhlola ukuziphatha kokuvutha kanye nokumelana nomlilo.
