M'zaka zaposachedwa, kufunikira kwa utsi wotsika-free-free (lszh) kumatha chifukwa cha phindu lawo komanso zachilengedwe. Chimodzi mwazinthu zazikulu zomwe zimagwiritsidwa ntchito zingwe izi zimadutsa polyethylene (xlpe).
1. Ndi chiyaniCholumikizidwa ndi polyethylene (xlpe)?
Polyithylene olumikizidwa, nthawi zambiri mwachidule xlpe, ndi zinthu za polyethylene zomwe zasinthidwa ndi kuwonjezera kwa mtanda. Njira yolumikizirana yolumikizirana imathandizira kutentha, makina ndi mankhwala a zinthuzo, zomwe zimapangitsa kuti zikhale zabwino pazogwiritsa ntchito zosiyanasiyana. XLPA imagwiritsidwa ntchito kwambiri pakumanga makina omanga, hydraulic yotentha kwambiri komanso makina ozizira, madzi apakhomo ndi makulidwe amphamvu kwambiri.
2. Ubwino wa XLPE
Xlpe Kutulutsa kwa XLPE kumapereka zabwino zambiri pazinthu zachikhalidwe monga polyvinyl chloride (pvc).
Ubwinowu ndi monga:
Kukhazikika kwamafuta: Xlpe imatha kupirira kutentha kwambiri popanda kuphatikizika chifukwa choyenera kumagwiritsidwe ntchito kwambiri.
Kukaniza kwamphamvu kwa mankhwala: Malo otsekemera ali ndi kukana kwakukulu kwa mankhwala, ndikuwonetsetsa kulimba m'malo mwazinthu zovuta.
Mphamvu yamakina: Xlpe imakhala ndi katundu wabwino kwambiri, kuphatikizapo kukana kuvala komanso kupsinjika.
Chifukwa chake, zida za XLP zimagwiritsidwa ntchito nthawi zambiri zamagetsi, magalimoto amatsogolera, zingwe zopepuka kwambiri, zingwe zam'madzi zam'madzi, zingwe zam'madzi zam'madzi komanso zingwe zotumiza mphamvu.
Polyethylene Droplink
Kudutsa polyethylene kumatheka ndi njira zosiyanasiyana, kuphatikiza radiation, peroxide ndi silane crossling. Njira iliyonse ili ndi maubwino ake ndipo imatha kusankhidwa molingana ndi zomwe mukufuna. Mulingo wa mtanda umakhudza kwambiri katundu wazinthuzo. Kuchulukitsa kwapamwamba, zabwino kwambiri zamafuta ndi makina.
3. Ndi chiyani?utsi wotsika-free (lszh)Zipangizo?
Zida zochepetsetsa zoseweretsa (LSZH) zimapangidwa kuti zinsinsi ziwoneke ndi utsi wocheperako poyaka ndipo musatulutse utsi wamapouni. Izi zimawapangitsa kukhala oyenera kugwiritsa ntchito malo okhala mitsempha ndi madera omwe amakhala ndi mpweya wabwino kwambiri, monga ma ngalande, mobisa sitima zapamtunda ndi nyumba zaboma. Nthanzi za LSZh zimapangidwa ndi ma thermoplastic kapena ma thermoset ndipo imapanga utsi wotsika kwambiri komanso utsi wamagetsi, ndikuwonetsetsa kuti zikuwoneka bwino ndikuchepetsa chiopsezo chamoto.
4. LSZH CRICT GAID
Zida za LSZh zimagwiritsidwa ntchito m'njira zosiyanasiyana pomwe nkhawa ndi zovuta zachilengedwe ndizotsutsa.
Mapulogalamu ena ofunikira akuphatikizapo:
Zida zankhondo za anthu onse: Zingwe za LSZh zimagwiritsidwa ntchito pagulu monga ma eyapoti, malo ogulitsira njanji komanso zipatala kuti zitsimikizire chitetezo pamoto.
Zingwe zoyendera: Zingwe izi zimagwiritsidwa ntchito pamagalimoto, ndege, kuphunzitsa magalimoto ndi zombo kuti muchepetse chiopsezo cha mikangano yoopsa pakachitika moto.
Tynel ndi Mobisa Nkhondo Zapamwamba za Lyz: Makhalidwe opanda utsi ndi mawonekedwe omasuka, omwe amawapangitsa kuti azigwiritsa ntchito mumsewu komanso mobisa sitima zapamtunda.
Zingwe za kalasi: Zingwe za LSzh zimagwiritsidwa ntchito mu zingwe za kalasi ya B1, zomwe zimapangidwa kuti zithetse miyezo yamoto yamoto ndipo imagwiritsidwa ntchito m'mitundu yayitali komanso zomangamanga zina.
Kupita patsogolo kwaposachedwa mu xlpe ndi lszh kuwunika momwe zinthu zikuthandizira ndikukulitsa ntchito zake. Zosiyanasiyana zimaphatikizapo kukula kwa polyethylene wolumikizidwa (xlhdpe), omwe apitizitsa kutentha ndi kulimba.
Kusintha ndi kokhazikika, kolumikizidwa kwa polyethylene (xlpe) ndi masiteni otsika zero-halogen (lszh) zinthu zambiri zimagwiritsidwa ntchito kwambiri m'mafakitale ochuluka, mphamvu zamankhwala. Mapulogalamu awo akupitilizabe kukula ndi kupititsa patsogolo kupititsa patsogolo ukadaulo komanso kufunika kowonjezereka kwa zinthu zotetezeka komanso zachilengedwe zambiri.
Monga momwe zinthu zodalirira komanso zodalirika zodalirika zimapitilira, xlpe ndi LSZh ikuyembekezeka kuchitapo kanthu pokwaniritsa zofunikira izi.
