Kodi Lead Stabilizers ndi chiyani? Kodi ntchito ya lead mu PVC ndi yotani?

Zokhazikika za lead, monga momwe dzinalo likusonyezera, ndi mtundu wa chokhazikika chomwe chimagwiritsidwa ntchito popanga polyvinyl chloride (PVC) ndi ma polima ena a vinyl. Zokhazikikazi zimakhala ndi mankhwala a lead ndipo zimawonjezeredwa ku mapangidwe a PVC kuti apewe kapena kuchepetsa kuwonongeka kwa kutentha kwa polima panthawi yokonza ndi kugwiritsa ntchito.Zokhazikika za lead mu PVCakhala akugwiritsidwa ntchito kwambiri m'makampani opanga PVC, koma kugwiritsa ntchito kwawo kwachepa m'madera ena chifukwa cha nkhawa zachilengedwe komanso thanzi zomwe zimagwirizanitsidwa ndi lead.

Mfundo zazikulu zokhudzazokhazikika za leadkuphatikizapo:

 

Njira Yokhazikitsira Zinthu:

Zolimbitsa mphamvu za lead zimagwira ntchito poletsa kuwonongeka kwa kutentha kwa PVC. Zimalepheretsa zinthu zomwe zimapangidwa ndi asidi zomwe zimapangidwa panthawi ya kusweka kwa PVC kutentha kwambiri, zomwe zimaletsa kutayika kwa kapangidwe ka polima.

 

Mapulogalamu:

Zolimbitsa mphamvu za lead zakhala zikugwiritsidwa ntchito pa ntchito zosiyanasiyana za PVC, kuphatikizapo mapaipi, zotetezera mawaya, ma profiles, mapepala, ndi zipangizo zina zomangira.

 

Kukhazikika kwa Kutentha:

Amapereka mphamvu yolimbitsa kutentha bwino, zomwe zimathandiza kuti PVC ikonzedwe kutentha kwambiri popanda kuwonongeka kwakukulu.

 

Kugwirizana:

Zolimbitsa mphamvu za lead zimadziwika chifukwa chogwirizana ndi PVC komanso kuthekera kwawo kusunga mawonekedwe a polima ndi makina.

 

Kusunga Utoto:

Zimathandizira kuti utoto wa zinthu za PVC ukhale wolimba, zomwe zimathandiza kupewa kusintha kwa mtundu komwe kumachitika chifukwa cha kutentha.

 

Zoganizira Zokhudza Malamulo:

Kugwiritsa ntchito zinthu zolimbitsa thupi monga lead kwakhala kukuchulukirachulukira chifukwa cha mavuto azachilengedwe komanso thanzi omwe amabwera chifukwa cha kukhudzana ndi lead. Lead ndi chinthu chapoizoni, ndipo kugwiritsa ntchito kwake pazinthu zogwiritsidwa ntchito ndi anthu komanso zipangizo zomangira kwachepetsedwa kapena kuletsedwa m'madera osiyanasiyana.

 

Kusintha kwa Njira Zina:

 

Potsatira malamulo okhudza chilengedwe ndi thanzi, makampani opanga PVC asintha njira zina zokhazikitsira zinthu zomwe sizikhudza chilengedwe. Zokhazikitsira zinthu zochokera ku calcium, zokhazikitsira zinthu za organotin, ndi zina zomwe sizili ndi lead zikugwiritsidwa ntchito kwambiri mu mapangidwe a PVC.

 

Zotsatira za Chilengedwe:

Kugwiritsa ntchito zinthu zolimbitsa thupi monga lead stabilizer kwadzetsa nkhawa yokhudza kuipitsidwa kwa chilengedwe komanso kufalikira kwa lead. Chifukwa cha zimenezi, anthu ayesetsa kuchepetsa kudalira zinthu zolimbitsa thupi monga lead stabilizer kuti achepetse kuwononga chilengedwe.

 

Ndikofunikira kudziwa kuti kusintha kuchoka pa zolimbitsa thupi za lead kukuwonetsa njira yowonjezereka yopangira njira zosamalira chilengedwe komanso zoganizira zaumoyo mumakampani a PVC. Opanga ndi ogwiritsa ntchito akulimbikitsidwa kugwiritsa ntchito njira zina zomwe zimakwaniritsa zofunikira za malamulo ndikuthandizira kuti zinthu zizikhala bwino. Nthawi zonse khalani odziwa zambiri za malamulo aposachedwa komanso machitidwe amakampani okhudzana ndi kugwiritsa ntchito zolimbitsa thupi.
