Trash Can Production Process Analysis
Sechikamu chakakosha chezvivakwa zvehutsanana hwemadhorobha, marara anogona kugadzira maitiro anokanganisa kusimba kwechigadzirwa, aesthetics, uye kushanda kwezvakatipoteredza. Kugadzirwa kwemarara kwemazuva ano kunosanganisira matanho mana akakosha: kugadzirira zvinhu, kuumba jekiseni, kurapwa kwepamusoro, uye kusangana uye kuyedzwa.
Iyo mbishi nhanho yekugadzirira inoda kuomarara zvinhu kuongorora. Marara emarara ekanzuru anowanzo shandisa mamiriro ekunze-mapurasitiki asingachinjiki seakakwira-density polyethylene (HDPE) kana polypropylene (PP). Masterbatch uye zvinhu zvakadzokororwa (zvisingapfuuri 30%) zvakasanganiswa muchiyero uchishandisa otomatiki metering sisitimu kuti ive nechokwadi chekusimba kwezvinhu uye kutevedzera GB/T 28019-2020 zviyero zvekuchengetedza kwezvakatipoteredza. Magaba emarara eindasitiri-egiredhi anogonawo kubatanidza zvinodzora moto kana kuti anti-corrosion agents.
Jekiseni molding inzira yakakosha. Mushure mekunyungudutswa pa 200-280℃, mbishi inobairwa muforoma chaiyo pachishandiswa muchina wekupeta jekiseni remajekiseni pakumanikidzwa kwe15-25 MPa. Kutenderera kwekutonhora kunotora anenge 30-90 masekonzi (zvinoenderana nehuwandu hwechigadzirwa). Mold tembiricha inodzorwa pakati pe40-60 dhigirii kuderedza deformation. Makuru emarara anoda akawanda-cavity molds kana gasi-anobatsira kuumba tekinoroji kuti avandudze kugadzirwa.
Kurapa kwepamusoro kunosanganisira kudhinda nekupfapfaidza. Mavara nemapatani zvinodhindwa pachishandiswa UV offset printing kuti iwane UV-kudzima kuramba. Marara emarara ekunze anogaroiswa poda yemagetsi-yakanamwa, nekukora kwe80-120μm. Kurapa pa180℃kunobatsira kusakara uye anti-kunamira zvinhu. Zvimwe zvigadzirwa zvemhando yepamusoro zvinogadzirwa nesimbi isina tsvina uye zvinoda kukwenenzverwa kana kukweshwa.
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).
Maitiro ese anogona kudzvanya-nguva yekugadzira chidimbu kusvika isingasviki maminetsi maviri kuburikidza neatomatiki kugadzira. Panguva imwe cheteyo, inotsamira pahurongwa hweMES kuwana-maitiro akazara ekutarisisa, kuona kuti marara anogona kuchengetedza hupenyu hwesevhisi hwemakore 5-8 munzvimbo dzakaoma kunzwisisa.
