Zokhazikika za Lead Compound
Chokhazikika cha lead ndi chowonjezera chogwiritsidwa ntchito m'njira zosiyanasiyana chomwe chimabweretsa zinthu zambiri zabwino, zomwe zimapangitsa kuti chikhale chisankho chofunidwa kwambiri m'mafakitale osiyanasiyana. Kukhazikika kwake kwapadera pa kutentha kumatsimikizira kuti kapangidwe kake ndi magwiridwe antchito a zinthu za PVC ngakhale kutentha kwambiri. Kupaka mafuta kwa chokhazikikacho kumathandiza kukonza bwino panthawi yopanga, ndikuwonjezera magwiridwe antchito onse opanga.
Ubwino wina waukulu uli mu kukana kwake nyengo. Zinthu za PVC zikakumana ndi nyengo zosiyanasiyana, chozitetezera chimatsimikizira kuti zimasunga mawonekedwe ake enieni, zomwe zimapangitsa kuti zikhale zoyenera kugwiritsidwa ntchito m'nyumba komanso panja.
Kuphatikiza apo, lead stabilizer imapereka mwayi wosavuta kugwiritsa ntchito popanga fumbi, zomwe zimapangitsa kuti ikhale yosavuta komanso yotetezeka kugwiritsa ntchito panthawi yopanga. Ntchito zake zambiri komanso kusinthasintha kwake zimapangitsa kuti ikhale yoyenera kugwiritsidwa ntchito m'njira zosiyanasiyana, zomwe zimapangitsa kuti igwiritsidwe ntchito kwambiri m'mafakitale osiyanasiyana.
Pakukonza PVC, chokhazikitsa mphamvu cha lead chimagwira ntchito yofunika kwambiri poonetsetsa kuti zinthuzo zikusungunuka mofanana komanso mosalekeza. Izi zimathandiza kuti zinthuzo zigwiritsidwe ntchito bwino komanso moyenera, zomwe zimapangitsa kuti zinthu zikhale zabwino kwambiri komanso zogwira ntchito bwino.
| Chinthu | Zamkati mwa Pb% | ZolangizidwaMlingo (PHR) | Kugwiritsa ntchito |
| TP-01 | 38-42 | 3.5-4.5 | Mbiri za PVC |
| TP-02 | 38-42 | 5-6 | Mawaya ndi zingwe za PVC |
| TP-03 | 36.5-39.5 | 3-4 | Zopangira PVC |
| TP-04 | 29.5-32.5 | 4.5-5.5 | Mapaipi a PVC okhala ndi corrugated |
| TP-05 | 30.5-33.5 | 4-5 | Mabodi a PVC |
| TP-06 | 23.5-26.5 | 4-5 | Mapaipi olimba a PVC |
Kuphatikiza apo, kugwiritsa ntchito chida chokhazikika cha lead kumathandizira kuti zinthu za PVC zisakule, zomwe zimapangitsa kuti zikhale zolimba komanso zokhalitsa. Mphamvu ya chida chokhazikika ichi yokongoletsa pamwamba imawonjezera kukongola kwa zinthu zomaliza, zomwe zimapangitsa kuti zikhale zokopa kwambiri kwa ogula.
Ndikofunikira kudziwa kuti chokhazikitsira lead chiyenera kugwiritsidwa ntchito moyenera kuti tipewe zoopsa zilizonse zokhudzana ndi thanzi komanso chilengedwe zomwe zingachitike chifukwa cha mankhwala ochokera ku lead. Motero, opanga ayenera kutsatira malangizo ndi malamulo amakampani kuti atsimikizire kuti chowonjezera ichi chikugwiritsidwa ntchito mosamala komanso moyenera.
Pomaliza, chokhazikika cha lead chili ndi ubwino wambiri, kuyambira kukhazikika kwa kutentha ndi kukhuthala mpaka kukana nyengo komanso kunyezimira pamwamba. Kupanda fumbi komanso kugwira ntchito zambiri, komanso kugwira ntchito bwino kwambiri, kumapangitsa kuti chikhale chofunikira kwambiri pakukonza PVC. Komabe, ndikofunikira kwambiri kuyika patsogolo chitetezo ndikutsatira malamulo mukamagwiritsa ntchito zokhazikika zochokera ku lead kuti zitsimikizire kuti ogula komanso chilengedwe ali bwino.
