Ha ditlhoko tsa polokeho ya mollo di ntse di eketseha ho pholletsa le ditsamaiso tsa dipalangwang tsa diterene, ditsi tsa data, meaho e melelele, dipetlele le diporojeke tsa eneji e ntjhafatswang, dikheibole tsa Low Smoke Zero Halogen (LSZH) di fetoha kgetho e kgethwang bakeng sa ditshebediso tse ngata tsa bohlokwa. Bakeng sa bahlahisi ba dikheibole, LSZH ha se feela sehlopha sa dihlahiswa—e emela tsela ya theknoloji ya thepa e fapaneng ka ho feletseng ha e bapiswa le metswako ya setso ya PVC.
Thepa ea LSZH ke Eng?
LSZH (Halogen e sa Tletseng Mosi o Tlase), e tsejoang hape e le Low Smoke Halogen Free (LSHF), e bolela sehlopha sa thepa e thibelang malakabe e sireletsang tikoloho e sebelisoang bakeng sa ho kenya le ho thiba lithapo tsa thapo. Indastering ea lithapo, thepa ena hangata e aroloa e le metsoako ea HFFR (Halogen Free Flame Retardant).
Metswako ya LSZH hangata e thehilwe hodima di-resin tsa polyolefin tse kang polyethylene (PE) le ethylene-vinyl acetate (EVA). Di entswe ka di-halogen-free flame retardants, ho kenyeletswa aluminium hydroxide (ATH) le magnesium hydroxide (MDH), hammoho le di-antioxidants, di-lubricant, le di-processing assists. Ho fapana le metswako ya PVC, thepa ya LSZH ha e na chlorine, bromine, kapa dielemente tse ding tsa halogen.
Ha ho bapisoa le metsoako e tloaelehileng ea cable ea PVC, thepa ea LSZH e ka boloka ho thibela motlakase hantle le thepa ea mechini ha ka nako e ts'oanang e fokotsa tlhahiso ea mosi le mesi e senyang ea khase haholo nakong ea ho cha. Ka lebaka leo, li sebelisoa haholo lits'ebetsong tsa cable moo polokeho ea mollo e leng taba ea bohlokoa.
Phapang ke efe pakeng tsa LSZH le PVC?
Polyvinyl chloride (PVC) e ntse e le e 'ngoe ea thepa ea cable e sebelisoang haholo ka lebaka la theknoloji ea eona ea ts'ebetso e butsoitseng, katleho ea litšenyehelo, le ts'ebetso e leka-lekaneng ka kakaretso. E sebelisoa hangata ho aha lithapo tsa motlakase, lithapo tsa motlakase le lits'ebetsong tsa lithapo tsa indasteri.
Ka lehlakoreng le leng, thepa ea LSZH e thehiloe litsamaisong tsa polyolefin 'me e fihlella ho lieha ha mollo ka lintho tse thibelang mollo tse sa tloaelehang ho fapana le lintho tse nang le halogen. Liphapang tse kholo ka ho fetisisa lipakeng tsa tse peli lia totobala nakong ea mollo.
PVC e ka ntša mosi o mongata le likhase tse senyang tse nang le chlorine ha li chesoa. Ka lehlakoreng le leng, thepa ea LSZH e hlahisa mosi o fokolang haholo 'me ha e ntše likhase tse ngata tsa halogen acid. Sena se thusa ho boloka ponahalo nakong ea ho tlosoa ha thepa le ho fokotsa tšenyo ea lisebelisoa tsa motlakase le tsa elektroniki.
Ho phaella moo, thepa ea LSZH e tsamaisana hantle le litlhoko tsa polokeho le tikoloho tsa merero ea meralo ea motheo ea sejoale-joale, ho kenyeletsoa litsamaiso tsa lipalangoang tsa literene, litsi tsa data, boema-fofane, lipetlele le mehaho ea sechaba. PVC e ntse e fana ka melemo mabapi le litšenyehelo le katleho ea ts'ebetso, e leng se etsang hore e lokele lits'ebetso tse ngata tsa setso.
Ho ya ka pono ya ho hanyetsa mocheso, metswako ya LSZH e ka etswa ho fihlela ditekanyetso tsa mocheso tsa 70°C, 90°C, 105°C, le ho feta, ho latela ditlhoko tsa tshebediso. Metswako ya setso ya PVC hangata e sebediswa dihlahisweng tsa cable tse lekanyeditsweng ho 70°C kapa 90°C. Ka lebaka leo, thepa ya LSZH e ntse e ratwa haholo ditshebedisong tse hlokang polokeho e ntlafetseng le tshebetso e phahameng ya mocheso.
Ke Maemo afe a Lokelang ho Finyella Lisebelisoa tsa LSZH?
Lisebelisoa tsa 'nete tsa LSZH li tlameha ho latela maemo a tsebahalang a indasteri le litlhoko tsa liteko.
Bakeng sa ts'ebetso e se nang halogen, IEC 60754-1 le IEC 60754-2 hangata li boleloa ho lekola bongata ba likhase tsa halogen acid tse lokollotsoeng nakong ea ho cha, hammoho le asiti le conductivity ea likhase tsa ho cha. IEC 60754-2 e totobatsa hore boleng ba pH ba likhase tsa ho cha ha boa lokela ho ba ka tlase ho 4.3 'me conductivity ha ea lokela ho feta 10 μS/mm.
Bakeng sa ts'ebetso e tlase ea mosi, letoto la IEC 61034 le lekanya bongata ba mosi ka liteko tsa phetisetso ea leseli.
Ho phaella moo, tshebetso e thibelang malakabe hangata e lekolwa ho ya ka maemo a IEC 60332 le GB/T 18380, ha GB/T 19666 e totobatsa ditlhoko tsa dithapo tse thibelang malakabe le tse sa tjheseng.
Bakeng sa mebaraka ea kantle ho naha le merero ea machabeng, thepa ea cable le eona e hlokahala hangata ho latela melaoana ea tikoloho joalo ka RoHS le REACH.
Ke Hobane'ng ha Merero e Mengata e Khetha Likhoele tsa LSZH?
Ho amohelwa ho ntseng ho hola ha dithapo tsa LSZH ho bakwa ke ditlhoko tse ntseng di eketseha tsa polokeho ya mollo, tshireletso ya tikoloho le tshireletso ya thepa.
Melemo ea bohlokoa e kenyelletsa:
Fokotsa tlhahiso ea mosi nakong ea liketsahalo tsa mollo, ho ntlafatsa ponahalo ea ho tsoa le ho arabela maemong a tšohanyetso.
Ho fokotsoa ha ho lokolloa ha likhase tse senyang, ho thusa ho sireletsa litsamaiso tsa puisano, meralo ea motheo ea motlakase, lisebelisoa tsa setsi sa data, le lisebelisoa tse ling tsa elektroniki tse bonolo.
Ho latela melao e thata ea tikoloho le litlhaloso tsa projeke.
