I-LSZH iwuhlobo olufushane lwe-Low Smoke Zero Halogen.Lezi zintambo zakhiwe ngezinto zejakhethi ezingenazo izinto ze-halogenic ezifana ne-chlorine ne-fluorine njengoba lawa makhemikhali anobuthi lapho eshiswa.
Izinzuzo noma izinzuzo zekhebula le-LSZH
Okulandelayo izinzuzo noma izinzuzo zekhebula le-LSZH:
➨ Asetshenziswa lapho abantu beseduze kakhulu namakhebula ahlanganisa lapho bengawutholi umoya owanele uma kuba nomlilo noma kunezindawo zokungenisa umoya ezimbi.
➨Abiza kakhulu.
➨Zisetshenziswa ezinhlelweni zikaloliwe lapho izintambo zesignali yamandla kagesi aphezulu zisetshenziswa emhubheni ongaphansi komhlaba.Lokhu kuzonciphisa amathuba okunqwabelana kwamagesi anobuthi lapho izintambo zivutha.
➨Zakhiwa kusetshenziswa izinhlanganisela ze-thermoplastic ezikhipha intuthu elinganiselwe engenawo ama-halogen.
➨Azikhiqizi igesi eyingozi lapho zihlangana nemithombo yokushisa ephezulu.
Ijakhethi yekhebula ye-➨LSZH isiza ekuvikeleni abantu uma kuba nomlilo, intuthu kanye negesi eyingozi ngenxa yokushiswa kwamakhebuli.
Okubi noma ukungalungi kwekhebula le-LSZH
Okulandelayo yizingqinamba noma ububi bekhebula le-LSZH:
Ibhantshi lekhebula le-➨LSZH lisebenzisa u-% ophezulu wezinto zokugcwalisa ukuze linikeze intuthu ephansi kanye ne-halogen eyiziro.Lokhu kwenza ibhantshi likwazi ukumelana namakhemikhali/amanzi uma liqhathaniswa nekhebula elingelona i-LSZH.
➨Ijakhethi lekhebula le-LSZH liyaqhekeka phakathi nokufakwa.Ngakho-ke kudingeka izinto zokuthambisa ezikhethekile ukuze zingalimazi.
➨Inikeza ukuguquguquka okulinganiselwe ngakho ayiwafanele amarobhothi.
Uma ukuvikela okokusebenza noma abantu kuyisidingo sedizayini, cabangela izintambo ezinentuthu eziphansi zero-halogen (LSZH) ezinejakhethi.Akhipha intuthu enobuthi embalwa kunamajakhethi ekhebula asekelwe ku-PVC ajwayelekile.Ngokujwayelekile, ikhebula le-LSZH lisetshenziswa ezindaweni ezivalekile njengokusebenza kwezimayini lapho kukhathazeka khona ukungenwa komoya.
Uyini umehluko phakathi kwekhebula le-LSZH nezintambo ezivamile?
Umsebenzi kanye nepharamitha ye-LSZH fiber optic ifana nezintambo ezivamile ze-fiber optic, futhi isakhiwo sangaphakathi siyafana, umehluko oyisisekelo amabhantshi.I-LSZH fibre optic jackets imelana kakhulu nomlilo uma iqhathaniswa nezintambo ezijwayelekile ze-PVC ezinejakhethi, ngisho nalapho zibanjwe umlilo, izintambo ezishisiwe ze-LSZH zinikeza intuthu ephansi futhi azikho izinto ze-halogen, lesi sici asivikeli imvelo kuphela kodwa intuthu ephansi lapho sithola. kushisiwe nakho kubalulekile kubantu nasezikhungweni endaweni eshisiwe.
Ijazi le-LSZH lenziwe ngezinto ezikhetheke kakhulu ezingezona i-halogenated futhi ezinqanda ilangabi.Ijekhethi yekhebula ye-LSZH yakhiwe ngezinhlanganisela ze-thermoplastic noma ze-thermoset ezikhipha intuthu elinganiselwe futhi azinayo i-halogen lapho zichayeke emithonjeni ephezulu yokushisa.Ikhebula le-LSZH lehlisa inani legesi enobuthi negqwalayo ekhishwa ngesikhathi sokusha.Lolu hlobo lwento ngokuvamile lusetshenziswa ezindaweni ezingenawo umoya ohlanzekile njengezindiza noma izimoto zikaloliwe.Amabhantshi e-LSZH nawo aphephile kunamajakhethi ekhebula anesilinganiso se-Plenum angavutha kancane kodwa asakhipha intuthu enobuthi ne-caustic uma eshiswa.
Intuthu ephansi enguziro halogen isithandwa kakhulu futhi, kwezinye izimo, imfuneko lapho ukuvikelwa kwabantu nezinto zokusebenza egesini enobuthi negqwalayo kubalulekile.Lolu hlobo lwekhebula luhlala luhileleke emlilweni omncane kakhulu kukhiqizwa intuthu encane eyenza le ntambo ibe yisinqumo esihle kakhulu ezindaweni ezivalekile njengemikhumbi, imikhumbi-ngwenya, izindiza, amakamelo amaseva asezingeni eliphezulu nezikhungo zenethiwekhi.
Uyini umehluko phakathi kwezintambo ze-PVC ne-LSZH?
Ngokomzimba, i-PVC ne-LSZH ihluke kakhulu.Ama-patchcords e-PVC athambile kakhulu;Ama-patchcords e-LSZH aqinile kakhulu ngoba aqukethe inhlanganisela ye-flame retardant, futhi athandeka kakhulu ngobuhle.
Ikhebuli ye-PVC (eyenziwe nge-polyvinyl chloride) inejazi elikhipha intuthu emnyama enzima, i-hydrochloric acid, namanye amagesi anobuthi lapho isha.Ikhebula le-Low Smoke Zero Halogen (LSZH) linebhantshi elimelana nelangabi elingakhiphi intuthu enobuthi ngisho noma livutha.
I-LSZH ibiza kakhulu futhi ayiguquguquki kancane
Izintambo ze-LSZH ngokuvamile zibiza ngaphezu kwekhebula le-PVC elilinganayo, futhi izinhlobo ezithile aziguquguquki kancane.Ikhebula le-LSZH linemikhawulo ethile.Ngokwamazinga e-CENELEC EN50167, 50168, 50169, amakhebuli ahloliwe kufanele angabi ne-halogen.Kodwa-ke, awukho umthetho ofanayo osasebenza kumakhebuli angahloliwe.
