LSZH: Tsis tshua muaj pa luam yeeb xoom Halogen; PVC: Polyvinyl Chloride, muaj chlorine thiab halogens. Thawj lub hauv paus ntsiab lus rau kev xaiv: rau cov chaw kaw / thaj chaw uas muaj coob tus neeg / kev khiav tawm hluav taws, xaiv LSZH; rau qhov chaw qhib zoo tib yam thiab cov uas muaj peev nyiaj tsawg, xaiv PVC.
I. Kev sib piv qhov tseem ceeb
|
Yam khoom |
PVC kab |
LSZH tsis tshua muaj pa taws thiab tsis muaj halogen cable |
|
Halogen |
Chlorine (halogen) |
Halogen dawb (tsis muaj chlorine, fluorine, thiab lwm yam) |
|
Cov khoom ntawm combustion |
Ib qho loj ntawm cov pa luam yeeb dub, tso HCl (hydrogen chloride), cov pa roj corrosive thiab lom. Thaum nws nkag mus rau hauv dej, nws tsim hydrochloric acid, uas tuaj yeem cuam tshuam cov khoom siv thiab ua rau lub ntsws ua pa. |
Cov pa luam yeeb tawm tsawg heev, nrog lub teeb thiab daj ntseg, yuav luag tsis muaj halogenated acid toxic gases. Cov khoom combustion feem ntau yog dej vapor, thiab tsis tshua muaj corrosiveness rau cov khoom siv. |
|
Kub tiv taus |
Ordinary PVC tuaj yeem tiv taus 70℃ntev; Thaum tshav kub kub-resistant PVC tuaj yeem ncav cuag 90 degree. |
Feem ntau ntawm 90℃rau ib lub sij hawm ntev, nrog zoo thermal stability |
|
Mechanical xav |
Cov tawv nqaij sab nrauv yog mos, khoov zoo, yog ruaj thiab khawb-resistant, thiab yooj yim rau khoov thaum lub sij hawm installation. |
Harder nyob rau hauv kev ntxhib los mos, nto yog nquag khawb. Nws dhau los ua nkig ntau dua ntawm qhov kub thiab txias thiab yuav tsum tau khoov lub vojvoog loj dua. |
|
Nqi |
Pheej yig, feem ntau siv hauv engineering, ntawm kev lag luam |
Tus nqi siab dua PVC (20% - 60% siab dua, nyob ntawm qhov specification) |
II. Siv tau Scenario (Kev xaiv tsom xam)
✅ Yuav tsum / nyiam xaiv LSZH (WDZ, WDZN series cables)
Rau qhov chaw uas muaj kev nyab xeeb hluav taws yog qhov yuav tsum tau ua lossis pom zoo, ua kom cov neeg ua haujlwm khiav tawm thiab tiv thaiv cov cuab yeej precision:
- Metro, tunnels, underground yeeb nkab galleries, underground garage cable shafts
- Tsev kho mob, tsev kawm ntawv, khw malls, tshav dav hlau, chaw nres tsheb, thiab lwm yam . - cov vaj tse uas muaj neeg coob coob
- Cov tsev siab siab, kev khiav tawm txoj hauv kev, pa luam yeeb thiab cua tshuab chav
- Cov chaw khaws ntaub ntawv, chav computer, chav tswj hwm (qhov hluav taws kub ua rau muaj kuab lom tuaj yeem ua rau cov servers thiab cov khoom siv hluav taws xob tsis muaj zog)
Cov kev cai tiv thaiv hluav taws hauv tsev: Chav I cov tsev siab siab, cov chaw muaj neeg coob, cov chaw nyob hauv av, feem ntau yuav tsum muaj cov kab hluav taws xob tsawg thiab tsis muaj halogen.
✅ Xaiv PVC (ZR-PVC nplaim-retardant PVC, BV / RVV, thiab lwm yam)
Rau qhov chaw zoo tib yam uas tsis tas yuav tsum muaj pa taws tsawg thiab tsis muaj halogen:
- Ordinary ib-zaj dab neeg factories, sab nraum zoov nyiaj siv ua haujlwm, ncaj qha faus, kho kom zoo nkauj hauv tsev (cov tsev tsis yog-tsev loj)
- Qhib qhov chaw, qhov chaw zoo-ventilated, uas cov neeg ua haujlwm tsis nyob ntev
- Kev txwv nyiaj txiag, tsuas yog xav tau cov nplaim hluav taws xob yooj yim, tsis tas yuav tsum haus luam yeeb tsawg thiab tsis muaj halogen.
Lus Cim: PVC kuj tuaj yeem ua rau cov nplaim hluav taws kub hnyiab PVC (ZR-PVC), nplaim hluav taws kub tsis txhais tau tias tsis muaj pa taws tsawg thiab tsis muaj halogen; Thaum tua hluav taws, nws tseem tso pa tawm ntau cov pa luam yeeb dub thiab tso tawm cov pa phem halogenic.
III. Kev xaiv yuam kev
- ❌ "Nplaim-retardant PVC yog sib npaug rau cov pa taws tsawg thiab halogen-dawb" nplaim retardancy tsuas yog tiv thaiv cov nplaim taws; Txawm hais tias cov nplaim hluav taws kub zoo li cas PVC, nws tseem tso pa tawm ntau cov pa luam yeeb dub thiab tso tawm cov pa phem halogenic.
- ❌ LSZH=LSZH Tsis-combustible LSZH yog hom nplaim hluav taws kub, tsis muaj pa taws, thiab tsis muaj tshuaj lom, tsis yog hluav taws kub. Txawm tias muaj hluav taws xob txuas ntxiv mus, nws tseem yuav hlawv.
- ❌ LSZH muaj hluav taws xob zoo dua. Nrog tib lub rwb thaiv tsev qauv, lub peev xwm ntawm hluav taws xob yog qhov zoo ib yam; Qhov sib txawv yog nyob rau hauv cov yam ntxwv ntawm kev nyab xeeb hluav taws, tsis yog conductivity.
IV. Cov lus qhia txog kev tsim kho
- LSZH: Lub vojvoog khoov yuav tsum nthuav dav. Thaum tuav thiab tso, xyuam xim rau kev tiv thaiv lub tsho sab nrauv, raws li nws yuav raug khawb; nyob rau hauv ib puag ncig uas tsis tshua muaj kub, xyuam xim rau kev tiv thaiv kev tawg.
- PVC: Zoo yoog raws, yooj yim rau kev tso, hnav-tiv taus, zoo sab nraum zoov tiv thaiv kev faus neeg.
