Izithambisi ze-calcium zinc, njengezithambisi zokushisa ezinobungani nemvelo, zinezicelo ezimbonini eziningi futhi zingahlukaniswa ngezigaba ezilandelayo:
1, insimu yemikhiqizo ye-PVC
1. Izinto zokwakha
Kubandakanya amapayipi e-PVC, amaphrofayili, izinto zokufakelwa, amaphaneli, ozimele bamafasitela, phansi, njll., ikakhulukazi kusetshenziswa ukuzinza kwawo kokushisa kanye nokumelana nesimo sezulu.
2. Izintambo nezintambo
Ifanele izintambo nezintambo ezinezidingo ezingezona ezinobuthi nezinobungani nemvelo, inamandla okuqina okushisa kanye nokumelana nokungcola kwesibabule, futhi ihlangabezana nezindinganiso zemboni ezifana nezokwelapha kanye ne-elekthronikhi.
3. Imikhiqizo ethambile
Njengemipayipi ethambile, amafilimu asongiwe, isikhumba sokwenziwa, amabhande okuhambisa, amaphephadonga, amathoyizi, njll., anokugcotshwa okulungiselelwe kanye nokusebenza kahle kokucubungula.
4. Izinto ze-foam
Ezicathulweni zezicathulo ze-foam ezibunjiwe nge-PVC, ikhwalithi yobuso iyathuthukiswa ngokulawula ukugeleza kokuncibilika kanye nokufana kwe-foam ukuvimbela ukuqhekeka kweseli.
2, Amanye amasimu epulasitiki kanye ne-resin
1. Amapulasitiki ajwayelekile kanye namapulasitiki obunjiniyela
Kusetshenziswa ku-polypropylene (PP), i-polycarbonate (PC), i-polyamide (PA) kanye nezinye izinhlayiya ukuze kuthuthukiswe ukumelana nokushiswa kwe-oxidation kanye nokusebenza kokucubungula.
2. Izinto zokupakisha
Isetshenziswa ezimweni ezingenabo ubuthi nezinobungani nemvelo njengokupakisha ukudla kanye nokupakisha kwezokwelapha, ukuhlangabezana sobala kanye nezidingo zokuqina kokushisa.
3, izicelo zemboni ye-Terminal
1. Ukwakhiwa Kwezakhiwo Nezinto Zokwakha
Amapayipi, amaphaneli okuhlobisa, amaphrofayili omnyango namafasitela, njll. athembele ekuzinzeni kwawo kokushisa kwesikhathi eside kanye nokumelana nesimo sezulu.
2. Izimoto kanye Nezokuthutha
Izingxenye zangaphakathi zezimoto, imichilo yokuvala, njll. zinezici ezilula nezilwa nokuguga.
3. Ezokwelapha kanye Neze-elekthronikhi
Ama-catheter ezokwelapha, ama-casing amadivayisi kagesi, njll. ahambisana nezindinganiso zokuphepha ezingenabo ubuthi.
4, ubuchwepheshe bokucubungula obukhethekile
Ukubumba/ukukhipha/ukugoqa ngomjovo
Yenza ngokwezifiso ifomula ngokwendlela yokucubungula, njengokulinganisela amandla okuncibilika kanye nokugeleza kwamanzi kwezinto zezicathulo ze-foam ezibunjiwe ngomjovo, kanye nokugcizelela ubushelevu bomphezulu wamafilimu asongiwe.
Izithambisi ze-calcium zinc ziye zathatha indawo yezithambisi ze-lead cadmium zendabuko kancane kancane futhi zaba yizithasiselo eziyinhloko emkhakheni wokucubungula ipulasitiki ngenxa yobungani bazo bemvelo, ukuzinza, kanye nokusebenza kwazo okuningi.
Isikhathi sokuthunyelwe: Meyi-22-2025
