Kusanthula Njira Yopangira Zinyalala
Monga gawo lofunikira pazaukhondo wamatauni, njira zopangira zinyalala zimakhudza kukhazikika kwazinthu, kukongola, komanso momwe chilengedwe chimagwirira ntchito. Kupanga zinyalala zamakono kumaphatikizapo njira zinayi zofunika kwambiri: kukonza zinthu zopangira, kuumba jekeseni, kukonza pamwamba, kusonkhanitsa ndi kuyesa.
The zopangira kukonzekera siteji amafuna okhwima zinthu kuunika. Zinyalala za municipal zinyalala nthawi zambiri zimagwiritsa ntchito nyengo-mapulasitiki osagwira ntchito monga-density polyethylene (HDPE) kapena polypropylene (PP). Masterbatch ndi zipangizo zobwezerezedwanso (zosapitirira 30%) zimasakanizidwa molingana pogwiritsa ntchito makina opangira mita kuti atsimikizire kulimba kwa zinthu ndikutsatira GB/T 28019-miyezo ya 2020 yoteteza chilengedwe. Zonyamulira zinyalala za mafakitale-zingakhalenso ndi zoletsa moto kapena anti-corrosion agents.
Kuumba jekeseni ndi njira yofunika kwambiri. Akasungunulidwa pa 200-280 digiri , zopangirazo zimabayidwa mu nkhungu yolondola bwino pogwiritsa ntchito makina omangira jekeseni pa mphamvu ya 15-25 MPa. Kuzizira kumatenga pafupifupi masekondi 30-90 (kutengera kuchuluka kwazinthu). Kutentha kwa nkhungu kumayendetsedwa pakati pa 40-60 digiri kuti muchepetse deformation. Zinyalala zazikulu zimafuna nkhungu zokhala ndi zingwe zambiri kapena ukadaulo wopangira gasi kuti upangitse bwino.
Chithandizo chapamwamba chimaphatikizapo kusindikiza ndi kupopera mbewu mankhwalawa. Zolemba ndi mapatani amasindikizidwa pogwiritsa ntchito makina osindikizira a UV kuti akwaniritse UV-kukana kuzimiririka. Zinyalala zakunja nthawi zambiri zimakutidwa ndi electrostatically powder{3}}zokutira, ndipo makulidwe ake ndi 80-120μm. Kuchiritsa pa digirii 180 kumapangitsa kuti musavale komanso kuletsa-zomata. Zogulitsa zina zapamwamba zimapangidwa ndi chitsulo chosapanga dzimbiri ndipo zimafuna kupukuta kapena kupukuta.
The final stage is assembly testing. Trash cans with inner containers require rubber sealing rings to be installed. The entire product must pass load tests (≥50kg static pressure), drop tests (1.5m height), and dimensional accuracy measurements (tolerance ±1.5mm). Qualified products are disinfected with ozone before packaging and labeled with material symbols according to international standards (such as a recycling symbol >7).
Ntchito yonseyi imatha kufinya nthawi imodzi-yopanga kupanga kuti isapitirire mphindi 2 kudzera pa makina opanga makina. Panthawi imodzimodziyo, imadalira dongosolo la MES kuti lizitha kufufuza bwinobwino-zonse, kuonetsetsa kuti zinyalalazo zisunga moyo wautumiki wa zaka 5-8 m'malo ovuta.
