Njengoba ulwazi olukhulayo ngokuvikelwa kwemvelo lukhula, izintambo ze-Low Smoke Zero Halogen (LSZH) ziya ngokuya ziba imikhiqizo eyinhloko emakethe. Uma kuqhathaniswa nezintambo zendabuko, izintambo ze-LSZH azigcini nje ngokunikeza ukusebenza okuphezulu kwemvelo kodwa futhi zibonisa izinzuzo ezibalulekile ekusebenzeni kokuphepha nokudlulisa. Lesi sihloko sizohlola izinzuzo, izinkinga ezingaba khona, kanye nemikhuba yentuthuko yesikhathi esizayo yezintambo ze-LSZH ngezindlela eziningi.
Izinzuzo Zezintambo ze-LSZH
1. Ubungane Bemvelo
I-LSZHIzintambo zenziwe ngezinto ezingenayo i-halogen, ezakhiwe ngokuyinhloko ngezinto ezinobungani nemvelo njenge-polyolefin, futhi azinazo izinto eziyingozi njenge-lead noma i-cadmium. Uma zishiswa, izintambo ze-LSZH azikhiphi amagesi anobuthi. Uma kuqhathaniswa nezintambo ze-PVC zendabuko, izintambo ze-LSZH azikhiphi nhlobo umusi oyingozi ngesikhathi sokusha, okunciphisa kakhulu izingozi zemvelo nezempilo ezibangelwa imililo.
Ngaphezu kwalokho, ngokusetshenziswa kabanzi kwezinto ze-LSZH, ukukhishwa kwekhabhoni embonini yezintambo kuye kwalawulwa ngempumelelo, okunegalelo ekukhiqizweni okuluhlaza kanye nentuthuko esimeme.
2. Ukuphepha
Izimfanelo ezinhle kakhulu zokuvimbela ilangabi zezintambo ze-LSZH zenza zingabi namathuba amaningi okusha emlilweni, zinciphise ukusabalala kwamalangabi futhi zithuthukise kakhulu ukuphepha kwezintambo. Ngenxa yezimpawu zazo eziphansi zentuthu, ngisho noma kwenzeka umlilo, inani lentuthu ekhiqizwayo liyancipha kakhulu, okwenza kube lula ukuphuma kwabantu kanye nemizamo yokusiza abantu abaphuthumayo. Ngaphezu kwalokho, izinto eziyingqayizivele ezisetshenziswa ezintanjeni ze-LSZH zikhiqiza amagesi anobuthi amancane uma zishiswa, zingabeki usongo empilweni yabantu.
3. Ukumelana Nokugqwala
Izinto ezingaphandle ze-sheath zezintambo ze-LSZH zibonisa ukumelana okuhle kakhulu nokugqwala, okwenza zifaneleke kakhulu ukusetshenziswa ezindaweni ezinomswakama ophezulu, i-salt spray, noma ukuchayeka kumakhemikhali. Kungakhathaliseki ukuthi kusezitshalweni zamakhemikhali, ezindaweni zikagesi, noma ezindaweni ezisogwini ezinezimo eziqinile zokugqwala, izintambo ze-LSZH zingagcina ukusebenza okuzinzile isikhathi eside, zigweme izinkinga zokuguga kanye nomonakalo izintambo zendabuko ezivame ukubhekana nazo ezindaweni ezinjalo.
4. Ukusebenza Kokudlulisa
Izintambo ze-LSZH zivame ukusebenzisa ithusi elingenawo umoya-mpilo (OFC) njengento yokuqhuba, okunikeza ukuhanjiswa okuphezulu kanye nokumelana okuphansi uma kuqhathaniswa nezintambo ezivamile. Lokhu kwenza izintambo ze-LSZH zikwazi ukufeza ukusebenza kahle kokudlulisela ngaphansi komthwalo ofanayo, okunciphisa ngempumelelo ukulahleka kwamandla. Ukusebenza kwazo okuhle kakhulu kukagesi kwenza izintambo ze-LSZH zisetshenziswe kabanzi ezilungiselelweni ezidinga ukudluliselwa kwedatha okusheshayo, okunamandla aphezulu, njengezikhungo zedatha kanye nezindawo zokuxhumana.
5. Ubude besikhathi eside
Izingqimba zokuvikela kanye nezendlalelo zezintambo ze-LSZH zivame ukwenziwa ngezinto ezimelana nokushisa okuphezulu kanye nezimelana nokuguga, okuzivumela ukuthi zikwazi ukumelana nezimo zokusebenza ezinzima futhi zandise impilo yazo yesevisi. Ngesikhathi sokusetshenziswa isikhathi eside, izintambo ze-LSZH azithinteki kakhulu yizici zangaphandle zemvelo, okugwema izinkinga ezifana nokuguga, ukuqina, kanye nokuqhekeka okuvamile ezintanjeni zendabuko.
Izinkinga Zezintambo ze-LSZH
1. Izindleko Eziphezulu
Ngenxa yobunzima bezinto zokusetshenziswa kanye nezinqubo zokukhiqiza ezisetshenziswa ezintanjeni ze-LSZH, izindleko zazo zokukhiqiza ziphakeme kakhulu. Ngenxa yalokho, izintambo ze-LSZH zivame ukubiza kakhulu kunezintambo ze-PVC zendabuko. Kodwa-ke, ngokwandiswa kwesilinganiso sokukhiqiza kanye nentuthuko eqhubekayo kwezobuchwepheshe, izindleko zezintambo ze-LSZH kulindeleke ukuthi zehle esikhathini esizayo.
2. Ubunzima bokufaka
Ukuqina okuphezulu kwezintambo ze-LSZH kungadinga amathuluzi akhethekile okusika nokugoba ngesikhathi sokufakwa, okwandisa ubunzima benqubo. Ngokuphambene nalokho, izintambo zendabuko ziguquguquka kakhudlwana, okwenza ukufakwa kwazo kube lula.
3. Izinkinga Zokuhambisana
Eminye imishini yendabuko kanye nezesekeli kungenzeka zingahambisani nezintambo ze-LSZH, okudinga ukuguqulwa noma ukushintshwa kwezinye izinhlelo zokusebenza ezisebenzayo. Lesi ngesinye sezizathu ezenza izintambo ze-LSZH zibhekane nemikhawulo emikhakheni ethile.
Izitayela Zokuthuthukiswa Kwezintambo ze-LSZH
1. Ukusekelwa Kwenqubomgomo
Njengoba izinqubomgomo zemvelo ziba nzima kakhulu emhlabeni jikelele, izindawo zokusetshenziswa kwezintambo ze-LSZH ziyaqhubeka nokukhula. Ikakhulukazi ezindaweni zomphakathi, ezokuthutha ngezitimela, izikhungo zamakhemikhali kaphethiloli, kanye nokufakwa kukagesi, ukusetshenziswa kwezintambo ze-LSZH sekuba yindlela yokuhweba embonini. Ukusekelwa kwenqubomgomo yezintambo ze-LSZH eShayina kuzoqhubekisela phambili ukwamukelwa kwazo emikhakheni eminingi.
2. Intuthuko Yezobuchwepheshe
Ngokuthuthuka okuqhubekayo kwesayensi yezinto zokwakha, ukusebenza kwezintambo ze-LSZH kuzoqhubeka nokuthuthuka, futhi izinqubo zokukhiqiza zizokhula kakhulu. Kulindeleke ukuthi izindleko zokukhiqiza zezintambo ze-LSZH zizoncipha kancane kancane, okwenza lo mkhiqizo wezintambo onobungani nemvelo futhi ophephile utholakale kalula kumakhasimende abanzi.
3. Isidingo Semakethe Esikhulayo
Njengoba ulwazi lomhlaba wonke ngokuvikelwa kwemvelo lukhula, kanye nokugcizelela ukuphepha nempilo, isidingo semakethe sezintambo ze-LSZH kulindeleke ukuthi sikhule kancane kancane. Ikakhulukazi ezimbonini ezifana nogesi, ezokuxhumana, kanye nezokuthutha, amathuba emakethe ezintambo ze-LSZH makhulu kakhulu.
4. Ukuhlanganiswa Kwemboni
Njengoba ubuchwepheshe buthuthuka futhi isidingo semakethe sikhuphuka, imakethe yekhebula le-LSZH izohlanganiswa kancane kancane embonini. Amabhizinisi athuthukile kwezobuchwepheshe nasezingeni eliphezulu azobusa imakethe, aqhube intuthuko enempilo yemboni yonke.
Isiphetho
Izintambo ze-LSZH, ezinezinzuzo eziningi ezifana nobungane bemvelo, ukuphepha, kanye nokumelana nokugqwala, sezibe yisinqumo esifanele sezimboni zesimanje ezifana namandla kagesi kanye nokuxhumana. Nakuba izindleko zazo zamanje ziphakeme futhi ukufakwa kwazo kuyinkimbinkimbi kakhulu, lezi zinkinga kulindeleke ukuthi zixazululwe kancane kancane ngentuthuko yezobuchwepheshe kanye nokusekelwa kwenqubomgomo, okwenza amathuba emakethe esikhathi esizayo ezintambo ze-LSZH athembise kakhulu.
Njengebhizinisi elihamba phambili embonini yezinto zokusetshenziswa kwezintambo nezintambo, i-OWcable izibophezele ekuhlinzekeni ngekhwalithi ephezuluInhlanganisela ye-LSZHukuhlangabezana nezidingo zokukhiqiza zezintambo ze-LSZH. Siyaqonda ukubaluleka kokuvikelwa kwemvelo nokuphepha, futhi siqhubeka nokwenza ngcono izinqubo zethu zokukhiqiza ukuqinisekisa ukuthi imikhiqizo yethu ihlangabezana nezindinganiso zomhlaba wonke. Uma ufuna umhlinzeki onokwethenjelwa we-LSZH compound, sicela uxhumane ne-OWcable. Sizokunikeza amasampula wamahhala nezixazululo zobungcweti ukusiza amaphrojekthi akho afinyelele ukusebenza okuphezulu kanye nemigomo yentuthuko esimeme.
