Hlobo luni lwezinkomishi zamanzi zepulasitiki ezingafanelekile

Hlobo luni lwezinkomishi zamanzi zepulasitiki ezingafanelekile? Sicela ubone:
Okokuqala, ukulebula akucacile. Umngane ojwayelene naye wakubuza, ingabe awubeki indaba kuqala ngaso sonke isikhathi? Kungani ungakwazi ukuziveza ngokucacile namuhla? Kunezinhlobo eziningi zezinto zokukhiqiza izinkomishi zamanzi epulasitiki, njenge: AS, PS, PP, PC, LDPE, PPSU, TRITAN, njll. Izinto zokukhiqiza izinkomishi zamanzi epulasitiki nazo ziyibanga lokudla. Ingabe udidekile? Basesezingeni lokudla. Kungani isihloko esandulele somhleli sathi ezinye izinto ziyingozi? Yebo, lokhu kuhlobene nendaba yokumaka okungacacile. Ngenxa yokuntula kwabathengi ulwazi mayelana nezinto zepulasitiki, ikakhulukazi abanakho ukuqonda okuncane kokuqukethwe okumelelwa yizimpawu zonxantathu zezinombolo phansi kwezinkomishi zamanzi zepulasitiki.

Lokhu kubangela ukuthi abathengi bacabange ukuthi izinkomishi zamanzi zepulasitiki abazithengayo ziphephile ekudleni, kodwa ngenxa yokusetshenziswa kabi, izinkomishi zamanzi zikhipha izinto eziyingozi. Isibonelo: I-AS, i-PS, i-PC, i-LDPE nezinye izinto azikwazi ukumelana namazinga okushisa aphezulu. Izinto ezinamazinga okushisa amanzi angaphezu kuka-70°C zizokhipha i-bisphenolamine (bisphenol A). Abangane bangasesha ngokuzethemba i-bisphenolamine ku-inthanethi. Izinto ezifana ne-PP, PPSU, ne-TRITAN zingakwazi ukumelana namazinga okushisa aphezulu futhi zingakhiphi i-bisphenolamine. Ngakho-ke, lapho abathengi bengazazi izidingo zokusetshenziswa kwezinto, umbuzo ovame kakhulu abathengi abaningi abawubuzayo ukuthi ingabe isitsha samanzi ashisayo sizokhubaza. I-Deformation ingushintsho kuphela esimweni futhi ukukhululwa kwezinto eziyingozi kuyizinto ezimbili ezihlukene.

Izinkomishi eziningi zamanzi zepulasitiki ezithengiswa emakethe zizoba nophawu lwenombolo engunxantathu ngezansi. Abanye abakhiqizi abanomthwalo wemfanelo bazongeza igama lempahla eduze kophawu lukanxantathu lwenombolo, njengokuthi: PP, njll. Nokho, kusenezinkomishi zamanzi zepulasitiki ezikhiqizwe abathengisi abangathembekile abangenazo izimpawu noma abanezimpawu ezingalungile. Ngakho-ke, ngicabanga ukuthi ukulebula okungacacile yinto ebaluleke kakhulu yokuqala. Ngesikhathi esifanayo, ngincoma futhi ukuthi wonke umkhiqizi wenkomishi yamanzi epulasitiki acabangele impilo yabathengi. Ngaphezu kophawu lwenombolo lukanxantathu negama lempahla, kukhona namalebula amelana nezinga lokushisa namalebula akhipha izinto eziyingozi. Ithiphu, ukuze abathengi bakwazi ukuthenga izinkomishi zamanzi zepulasitiki ezivumelana nabo ngokwemikhuba yabo yokuthenga.

Okwesibili, impahla. Lokhu esikhuluma ngakho lapha akulona uhlobo lwempahla, kodwa izinga lempahla ngokwayo. Kungakhathaliseki ukuthi hlobo luni lwempahla yepulasitiki yebanga lokudla esetshenziswayo, kunomehluko phakathi kwezinto ezintsha, izinto ezindala nezinto ezigaywe kabusha. Ukucwebezela kanye nomthelela wemikhiqizo esebenzisa izinto ezintsha akukwazi ukufezwa ngokusebenzisa izinto ezindala noma izinto ezigaywe kabusha. Izinto ezindala nezinto ezigaywe kabusha zingasetshenziswa ngaphansi kwesimo sokuphatha okujwayelekile kanye nokulawulwa kwekhwalithi okuqinile ngaphandle kokungcoliswa. Lokhu kuphinde kuhambisane nomqondo wokusetshenziswa kabusha kwezinto ezivikela imvelo. Nokho, kukhona abathengisi abangathembekile abasebenzisa izinto ezindala noma izinto ezigaywe kabusha ngaphandle kwezindinganiso, futhi indawo yokugcina imbi kakhulu. Baze bachoboze iziphetho nemisila yemikhiqizo edlule futhi bayisebenzise njengezinto ezigaywe kabusha. Sicela ubhekisise uma uthenga izinkomishi zamanzi zepulasitiki. Uma uthola ukuthi ezinye izinkomishi zamanzi epulasitiki zinokungcolile okuhlukahlukene noma inani elikhulu lokungcola, kufanele uyeke ngokuqinile futhi ungathengi izinkomishi ezinjalo zamanzi.

Okwesithathu, umsebenzi wenkomishi yamanzi. Uma uthenga inkomishi yamanzi epulasitiki, kufanele uhlole ngokucophelela izesekeli ezisebenzayo eziza nendebe yamanzi, uhlole ukuthi imisebenzi iphelele yini, futhi uqinisekise ukuthi izesekeli azonakaliswa noma ziwa. Lapho uthenga inkomishi yamanzi epulasitiki ngesikhathi esifanayo, kungcono ukuyisebenzisa ngokuya ngemikhuba yakho yokusebenzisa kanye nemisebenzi yenkomishi yamanzi. Hlola ukuthi ikhala lakho liyangqubuzana nelakho lapho uphuza amanzi, ukuthi igebe lesibambo kulula yini ukulibamba ngesandla sakho, njll. Umhleli ukhulume ngokuvala ezihlokweni eziningi. Uma ibhodlela lamanzi olithengayo lingavaleki kahle, lokhu kuyinkinga enkulu yekhwalithi.

Ekugcineni, ukumelana nokushisa. Umhleli ushilo ngaphambili ukuthi ukumelana nokushisa kwezinkomishi zamanzi epulasitiki kuhlukile, futhi ezinye izinto zizokhipha izinto eziyingozi ngenxa yokushisa okuphezulu. Ngakho-ke, lapho uthenga izinkomishi zamanzi epulasitiki, kufanele uqonde ngokucophelela izinto zokukhiqiza kanye nezici zezinto zokwakha. Ngithanda ukukhumbuza wonke umuntu lapha ukuthi amanye amabhrendi achaza ipulasitiki njengento ye-polymer, empeleni okuyi-gimmick ekubhalweni kokukopisha. Phakathi kwazo, izinkomishi zamanzi ezenziwe ngezinto ze-AS azimelani namazinga okushisa aphezulu, futhi azikwazi ukumelana nokuhluka kwezinga lokushisa. Amanzi ashisayo anezinga lokushisa eliphezulu noma amanzi eqhwa azobangela ukuthi impahla iqhekeke.
