Inzuzo yezinto zekhebula ze-halogen zero halogen (LSZH) ephansi
Into yekhebula le-Low Smoke Zero Halogen (LSZH) iyinto evikelayo futhi esheathing esetshenziswa ekwakheni izintambo zezinhlelo zokusebenza ezahlukahlukene. Amakhebuli e-LSZH aklanyelwe ukukhipha intuthu encane uma kuba nomlilo futhi angakhiqizi intuthu enobuthi, okuwenza alungele ukusetshenziswa ezindaweni ezivalekile noma ezingenawo umoya ohlanzekile.
Isidingo sezinto zekhebula le-LSZH siye sakhula eminyakeni yamuva nje ngenxa yokuqwashisa okukhulayo ngezingozi zempilo ezingaba khona ezihlobene nokusebenzisa izintambo zendabuko ze-PVC. Ukuze kuhlangatshezwane nalesi sidingo esikhulayo, abakhiqizi bebetshala imali ekuthuthukiseni izinto zekhebula ezingenantuthu ephansi, ezingenalo i-halogen ezingagcini nje ngokuhlangabezana nezindinganiso eziqinile zokuphepha kodwa futhi ezihlinzeka ngokusebenza okwengeziwe nokuhlala isikhathi eside.
Enye yezinzuzo eziyinhloko zezinto zekhebula le-LSZH zinciphisa umthelela wemvelo. Ngokungafani nezintambo zendabuko ze-PVC, ezikhulula amakhemikhali ayingozi endaweni ezungezile ngesikhathi sokukhiqiza nokulahlwa, izintambo ezingenayo intuthu encane ze-halogen zenziwa ngezinhlanganisela ze-thermoplastic ezingenawo ama-halogen nezinye izinto ezinobuthi. Lokhu kwenza izintambo ezingenantuthu ephansi ye-halogen zibe inketho eqhubekayo futhi evumelana nemvelo kumaphrojekthi wokwakha wesimanje nokuthuthukiswa kwengqalasizinda.
Ngaphandle kwezinzuzo zemvelo, izintambo ezingenayo intuthu ephansi ye-halogen nazo zaziwa ngezindawo zazo ezinhle kakhulu zokuphepha emlilweni. Uma evezwe emazingeni okushisa aphezulu, izintambo ze-PVC zendabuko zingakhipha amagesi anobuthi kanye nentuthu, okubeka izinsongo ezinkulu kubantu nempahla. Ngakolunye uhlangothi, amakhebuli angenayo intuthu encane, aklanyelwe ukunqanda ukusabalala komlilo futhi anciphise ukukhululwa kwezinto eziyingozi, anikeze indawo ephephile yokusebenza nendawo yokuhlala yawo wonke umuntu.
Ngaphezu kwalokho, izintambo ze-LSZH zimelana kakhulu nokuhuzuka, umswakama kanye namazinga okushisa aphakeme kakhulu, okwenza zifaneleke ezihlukahlukene zezinhlelo zokusebenza zangaphakathi nangaphandle. Kusukela ezindaweni zezimboni kuya ezakhiweni zokuhlala, izintambo ezingenantuthu ephansi ye-halogen ziyizixazululo ezinokwethenjelwa nezingabizi kakhulu zokunika amandla amasistimu kagesi nezokuxhumana.
Njengoba isidingo sezinto zamakhebula angenayo intuthu ephansi kanye ne-halogen siqhubeka sikhula, izinhlobonhlobo zemikhiqizo yamakhebula angenayo intuthu ephansi kanye ne-halogen emakethe kulindeleke ukuthi iqhubeke ukwanda. Abakhiqizi bayaqhubeka nokucwaninga futhi bathuthukise ukwakheka okusha nezindlela zokukhiqiza ukuze kuthuthukiswe ukusebenza kanye nokuguquguquka kwezintambo ze-LSZH, baqinisekise ukuthi bahlala beyindlela esebenzayo yezintambo zendabuko ze-PVC.
Kafushane, ukwamukelwa okwandayo kwezinto zekhebula ezingenantuthu ephansi, ezingenawo i-halogen kumelele ushintsho olukhulu oluya ezixazululweni zamakhebula eziphephile nezizinzile. Izintambo ezingenawo umusi omncane we-halogen zizodlala indima ebalulekile esikhathini esizayo semboni yekhebula ngokumelana nomlilo okuhle kakhulu, izinzuzo zemvelo kanye nezinhlelo zokusebenza eziningi. Njengoba imakethe yezinto zekhebula ezingenantuthu ephansi kanye ne-halogen iqhubeka nokukhula, kuyacaca ukuthi izintambo ezingenantuthu ephansi kanye ne-halogen zizohlala lapha.
