1. Kusintha Zinthu: Kuchokera ku PVC kupita ku LSZH Cable Materials
M'malo akuluakulu opezeka anthu ambiri monga m'masitolo akuluakulu, m'mabwalo a ndege, m'mabwalo a ndege, ndi m'zipatala, zingwe sizimangoyendetsa magetsi okha komanso zimakhala ngati chitetezo chofunikira kwambiri pakagwa moto.
Poyerekeza ndi zipangizo zachikhalidwe za PVC, zipangizo za Low Smoke Zero Halogen (LSZH) zikuyimira kukweza kwakukulu pakugwira ntchito kwa zinthu. Zipangizo za LSZH sizili ndi halogen (kapena zimagwirizana ndi malire a halogen omwe afotokozedwa mu miyezo monga IEC 60754). Pakayaka, sizitulutsa mpweya wowononga ndipo zimachepetsa kwambiri utsi wotulutsa. Kuchokera pamalingaliro azinthu, izi zimayang'ana bwino zoopsa zachitetezo zokhudzana ndi zipangizo zachikhalidwe zokhala ndi halogen pazochitika zamoto.
Kusintha kumeneku kuchoka pa zipangizo zachikhalidwe zokhala ndi halogen kupita ku zipangizo za chingwe za LSZH kwapangitsa kuti zingwe za LSZH zikhale njira yofunika kwambiri yopititsira patsogolo zingwe zamakono zoletsa moto komanso makina a zingwe zolimbana ndi moto.
2. Ubwino wa Magwiridwe Abwino: Kulephera kwa Moto, Utsi Wochepa, ndi Njira Yopanda Halogen
Kuchokera pakuwona zinthu za chingwe, ubwino waukulu wa zingwe zoletsa moto za LSZH uli m'mbali zitatu: kuchedwa kwa moto, kutulutsa utsi pang'ono, komanso kugwira ntchito kopanda halogen.
Zipangizo za chingwe cha LSZH zimagwiritsa ntchito makina oletsa moto opanda halogen, monga zitsulo zotchedwa metal hydroxides kapena phosphorous-nayitrogeni zomwe zimaletsa moto. Pa kutentha, makinawa amayamwa kutentha kwakukulu, amachepetsa mpweya woyaka, komanso amalimbikitsa kupanga chotchinga cha char cholimba, zomwe zimathandiza kuchepetsa kufalikira kwa moto ndikuchepetsa kudontha kwa madzi.
Nthawi yomweyo, zipangizo za LSZH zimatulutsa utsi wochepa kwambiri kuposa zipangizo zachikhalidwe za PVC, zomwe zimathandiza kuti zizioneka bwino kwambiri pakakhala moto komanso zimapangitsa kuti ntchito yochotsa zinthu iyende bwino. Kuphatikiza apo, popeza sizili ndi halogen, zinthu zoyaka moto makamaka zimakhala nthunzi yamadzi ndi carbon dioxide, popanda kutulutsa mpweya woopsa kapena wowononga, motero zimachepetsa kuvulaza kwachiwiri kwa anthu ndi zida.
Zinthu zophatikizidwazi zimapangitsa kuti zingwe za LSZH zoletsa moto zikhale zachitetezo pa ntchito za boma.
3. Zipangizo Zachingwe: Kupanga Njira Yotetezera Moto Yokhala ndi Zigawo Zambiri
Kuchokera pa kapangidwe ka chingwe, magwiridwe antchito a zingwe za LSZH zoletsa moto zimadalira kugwiritsa ntchito bwino zipangizo zingapo za chingwe.
LSZH pawiriImagwira ntchito ngati chida chakunja cha chingwe ndipo imatsimikizira momwe chingwecho chimagwirira ntchito kuti chisakhale ndi utsi wambiri, chisakhale ndi halogen, komanso kuti chisamayatse moto. Tepi ya LSZH imagwiritsidwa ntchito kulimbitsa kukhazikika kwa kapangidwe kake ndikukweza mulingo wonse wa chingwecho kuti chisamayatse moto.
Tepi ya mica ya Phlogopitendi chingwe chofunikira kwambiri chosapsa ndi moto. Pakakhala moto (nthawi zambiri pafupifupi 750–950°C, kutengera miyezo yoyesera monga IEC 60331 kapena BS 6387), imatha kusunga kutchinjiriza kwa magetsi kwa nthawi inayake, ndikupanga maziko a magwiridwe antchito a chingwe chosapsa ndi moto.
Tepi yotchingira madzi ndi ulusi wotchingira madzi zimagwiritsidwa ntchito kuti ziwonjezere kudalirika kwa nthawi yayitali m'malo ozizira komanso ovuta. Ngakhale sizimafunikira nthawi zonse kuti zigwiritsidwe ntchito m'nyumba zouma, zimagwiritsidwa ntchito kwambiri m'makina a zingwe zapansi panthaka, zobisika mwachindunji, komanso zakunja.
Pogwiritsa ntchito zipangizozi pamodzi, njira yotetezera ya zigawo zambiri yophatikiza kuchedwa kwa moto, kukana moto, utsi wochepa, komanso magwiridwe antchito opanda halogen ikhoza kukwaniritsidwa, kukwaniritsa zofunikira za miyezo yapadziko lonse lapansi.
4. Ntchito Zauinjiniya ndi Zofunikira Pakugwira Ntchito Kwazinthu
Mu ntchito monga nyumba zazikulu za anthu onse, njira zoyendera sitima, ndi zomangamanga zapansi panthaka, zipangizo za chingwe siziyenera kungopereka chitetezo cha moto komanso kuonetsetsa kuti ntchitoyo ndi yodalirika kwa nthawi yayitali.
Zipangizo za chingwe cha LSZH zogwira ntchito bwino nthawi zambiri zimakhala ndi mphamvu zabwino kwambiri zamakanika (monga kukana kukanda ndi kukana kugunda), kukana kukalamba kwambiri, komanso magwiridwe antchito okhazikika amagetsi oteteza. Nthawi yomweyo, zimapereka magwiridwe antchito abwino okonza, kuthandizira kutulutsa mwachangu komanso kupanga kwakukulu. Makhalidwe amenewa amatsimikiziridwa mwachindunji ndi kapangidwe ka zinthu ndi kuwongolera njira zopangira, zomwe zimapangitsa kuti chingwe chizigwira ntchito bwino.
Ponena za kutsatira malamulo, zingwe za LSZH nthawi zambiri zimafunika kuti zikwaniritse miyezo yapadziko lonse lapansi iyi:
Kulephera kwa moto: IEC 60332 mndandanda
Kuchuluka kwa utsi: IEC 61034
Kuchuluka kwa Halogen: IEC 60754
Kukana moto: IEC 60331 kapena BS 6387
Pamene zipangizo za chingwe zikupitilira kusintha kuti zikhale zotetezeka komanso zogwira ntchito bwino, kugwiritsa ntchito zipangizo za chingwe za LSZH, tepi ya phlogopite mica, ndi zipangizo zotchingira madzi zikuyembekezeka kukulirakulira, zomwe zikupanga mwayi watsopano kwa ogulitsa zipangizo za chingwe pamsika wapadziko lonse.
