Ukumelana nomlilo kwezintambo kubalulekile ngesikhathi somlilo, futhi ukukhethwa kwezinto ezibonakalayo kanye nomklamo wesakhiwo sesendlalelo sokusonga kuthinta ngokuqondile ukusebenza okuphelele kwekhebula. Isendlalelo esigoqayo ngokuvamile siqukethe isendlalelo esisodwa noma ezimbili zetheyiphu yokuvikela esongelwe okokufaka noma i-sheath yangaphakathi ye-conductor, ehlinzeka ngokuvikeleka, ukugcina ibhafa, ukwahlukanisa okushisayo, nemisebenzi yokulwa nokuguga. Okulandelayo kuhlola umthelela othize wesendlalelo esigoqayo ekumelaneni nomlilo ngokwemibono eyahlukene.
1. Umthelela Wezinto Ezivuthayo
Uma isendlalelo sokugoqa sisebenzisa izinto ezivuthayo (njengeItheyiphu yendwangu engalukiwenoma itheyiphu ye-PVC), ukusebenza kwazo ezindaweni ezinezinga lokushisa eliphezulu kuthinta ngokuqondile ukumelana nomlilo kwekhebula. Lezi zinto, lapho zishiswa ngesikhathi somlilo, zakha indawo yokuguqulwa kwe-insulation kanye nezingqimba zokumelana nomlilo. Lo mshini wokukhipha unciphisa ngokuphumelelayo ukucindezelwa kongqimba lokumelana nomlilo ngenxa yokucindezeleka okuphezulu kwezinga lokushisa, ukwehlisa amathuba okulimala kwesendlalelo sokumelana nomlilo. Ngaphezu kwalokho, lezi zinto zingakwazi ukuvimbela ukushisa phakathi nezigaba zokuqala zokuvutha, zibambezele ukudluliswa kokushisa kumqhubi futhi zivikele okwesikhashana isakhiwo sekhebula.
Nokho, izinto ezivuthayo ngokwazo zinamandla alinganiselwe okuthuthukisa ukumelana nomlilo kwekhebula futhi ngokuvamile zidinga ukusetshenziswa ngokuhambisana nezinto ezingashi. Isibonelo, kwezinye izintambo ezingashi, isendlalelo esengeziwe sokuvimbela umlilo (njengei-mica tape) ingangezwa phezu kwezinto ezivuthayo ukuze kuthuthukiswe ukumelana nomlilo. Lo mklamo ohlanganisiwe ungalinganisa ngempumelelo izindleko zempahla kanye nokulawulwa kwenqubo yokukhiqiza ezinhlelweni ezingokoqobo, kodwa imikhawulo yezinto ezivuthayo kusafanele ihlolwe ngokucophelela ukuze kuqinisekiswe ukuphepha kukonke kwekhebula.
2. Umthelela Wezinto Ezingashi
Uma isendlalelo sokugoqa sisebenzisa izinto ezingashi njengengilazi eboshiwe ye-fiber tape noma i-mica tape, ingathuthukisa kakhulu ukusebenza kokuvimbela umlilo kwekhebula. Lezi zinto zokwakha zakha umgoqo onganqamuki ilangabi emazingeni okushisa aphezulu, okuvimbela ungqimba olufakwayo ukuthi luthinte amalangabi ngokuqondile futhi lubambezele inqubo yokuncibilika kwe-insulation.
Kodwa-ke, kufanele kuqashelwe ukuthi ngenxa yesenzo sokuqinisa isendlalelo sokugoqa, ukucindezelwa kokunwetshwa kwesendlalelo se-insulation ngesikhathi sokuncibilika kwezinga lokushisa eliphezulu kungase kungadedelwa ngaphandle, okubangele umthelela omkhulu wokucindezela ungqimba lokumelana nomlilo. Lo mphumela wokugxilisa ingqondo ubonakala ikakhulukazi ezakhiweni zensimbi ze-armored tape, ezingase zinciphise ukusebenza kokumelana nomlilo.
Ukuze ulinganisele izidingo ezimbaxambili zokuqiniswa komshini kanye nokuhlukaniswa kwelangabi, izinto eziningi ezimelana nomlilo zingangeniswa ekwakhiweni kongqimba olugoqayo, futhi izinga lokugqagqana nokucindezela kokugoqa kungalungiswa ukuze kuncishiswe umthelela wokugxilisa ingqondo kungqimba lokumelana nomlilo. Ngaphezu kwalokho, ukusetshenziswa kwezinto eziguquguqukayo ezimelana nomlilo kuye kwanda kancane kancane eminyakeni yamuva. Lezi zinto zinganciphisa kakhulu inkinga yokugxila ekucindezelekeni ngenkathi ziqinisekisa ukusebenza kokuhlukaniswa nomlilo, kube nomthelela omuhle ekuthuthukiseni ukumelana nomlilo kukonke.
3. Ukusebenza Kokumelana Nomlilo kwe-Calcined Mica Tape
I-mica tape ehlanganisiwe, njengento yokugoqa esebenza kahle kakhulu, ingathuthukisa kakhulu ukumelana nomlilo kwekhebula. Lezi zinto zakha igobolondo eliqinile elivikelayo emazingeni okushisa aphezulu, elivimbela amalangabi namagesi aphezulu okushisa ukuba angangeni endaweni yomqhubi. Lesi sendlalelo esiminyene esivikelayo asigcini nje ngokuhlukanisa amalangabi kodwa futhi sivimbela ukwanda kwe-oxidation kanye nokulimala komqhubi.
I-calcined mica tape inezinzuzo zemvelo, njengoba ingenayo i-fluorine noma ama-halogens futhi ayikhiphi amagesi anobuthi lapho ishiswa, ihlangabezana nezidingo zemvelo zanamuhla. Ukuguquguquka kwayo okuhle kakhulu kuvumela ukuthi ivumelane nezimo zezintambo eziyinkimbinkimbi, ithuthukise ukumelana kwezinga lokushisa kwekhebula, iyenze ifaneleke ngokukhethekile izakhiwo eziphakeme kanye nokuthuthwa kwesitimela, lapho ukumelana nomlilo ophakeme kuyadingeka.
4. Ukubaluleka Komklamo Wesakhiwo
Idizayini yesakhiwo sesendlalelo sokugoqa ibalulekile ekwazi ukumelana nomlilo kwekhebula. Isibonelo, ukwamukela isakhiwo sokugoqa sezendlalelo eziningi (njenge-mica tape enezingqimba ezimbili noma eziningi) akugcini nje ngokuthuthukisa umphumela wokuvikela umlilo kodwa futhi kunikeza umgoqo ongcono wokushisa ngesikhathi somlilo. Ukwengeza, ukuqinisekisa ukuthi izinga lokugqagqana kwesendlalelo sokugoqa alikho ngaphansi kwama-25% kuyisinyathelo esibalulekile sokuthuthukisa ukumelana nomlilo kukonke. Izinga lokugqagqana eliphansi lingase liholele ekuvuzeni kokushisa, kuyilapho izinga eliphezulu lokugqagqana lingase lenyuse ukuqina komshini kwekhebuli, kuthinte ezinye izici zokusebenza.
Enqubweni yokuklama, ukuhambisana kwesendlalelo sokugoqa nezinye izakhiwo (njenge-sheath yangaphakathi kanye nezendlalelo zezikhali) kufanele kucatshangelwe. Isibonelo, ezimweni zokushisa okuphezulu, ukwethulwa kongqimba lwebhafa yezinto eziguquguqukayo kungahlakaza ngempumelelo ingcindezi yokwanda okushisayo futhi kunciphise ukulimala kongqimba lokumelana nomlilo. Lo mqondo wokuklama onezingqimba eziningi usetshenziswe kabanzi ekukhiqizeni ikhebula langempela futhi ubonisa izinzuzo ezibalulekile, ikakhulukazi emakethe ephezulu yezintambo ezingashi.
5. Isiphetho
Ukukhethwa kwempahla kanye nedizayini yesakhiwo yesendlalelo sokugoqa ikhebula kudlala indima ebalulekile ekusebenzeni kokumelana nomlilo kwekhebula. Ngokukhetha ngokucophelela izinto ezisetshenziswayo (njengezinto eziguquguqukayo ezingashi noma i-mica tape) kanye nokuthuthukisa ukwakheka kwesakhiwo, kungenzeka ukuthuthukisa ngokuphawulekayo ukusebenza kokuphepha kwekhebula uma kuba nomlilo futhi kuncishiswe ingozi yokungasebenzi kahle ngenxa yomlilo. Ukwenziwa ngcono okuqhubekayo komklamo wesendlalelo sokugoqa ekuthuthukisweni kobuchwepheshe bezintambo zesimanje kunikeza isiqinisekiso esiqinile sobuchwepheshe sokuzuza ukusebenza okuphezulu kanye namakhebuli angashi.
