ukubaluleka kwamanzi
Amanzi awumthombo wokuphila. Amanzi angathuthukisa umzimba womuntu, asize ukujuluka, futhi alawule izinga lokushisa lomzimba. Ukuphuza amanzi sekuphenduke umkhuba ophilayo kubantu. Eminyakeni yamuva nje, izinkomishi zamanzi bezilokhu zenza izinto ezintsha, njengenkomishi yosaziwayo ye-inthanethi “Indebe Enkulu Yesisu” kanye nentsha edumile ethi “Ibhakede leTon Ton”. "I-Big Belly Cup" ithandwa yizingane kanye nentsha ngenxa yesimo sayo esihle, kuyilapho ukusungulwa kwe-"Ton-ton Bucket" ukuthi ibhodlela limakwe ngesikhathi kanye nezikali zomthamo wamanzi okuphuza ukukhumbuza abantu ukuthi baphuze amanzi isikhathi. Njengethuluzi elibalulekile lamanzi okuphuza, kufanele ukhethe kanjani lapho uthenga?
Izinto eziyinhloko zezinkomishi zamanzi zebanga lokudla
Uma uthenga inkomishi yamanzi, into ebaluleke kakhulu ukubuka impahla yayo, ehlanganisa ukuphepha kwayo yonke indebe yamanzi. Kunezinhlobo ezine eziyinhloko zezinto zepulasitiki ezivamile emakethe: I-PC (i-polycarbonate), i-PP (i-polypropylene), i-tritan (i-Tritan Copolyester copolyester), ne-PPSU (i-polyphenylsulfone).
1. Izinto ze-PC
I-PC ngokwayo ayinabo ubuthi, kodwa i-PC (i-polycarbonate) impahla ayimelani nokushisa okuphezulu. Uma ishiswa noma ibekwe endaweni ene-acidic noma ene-alkaline, izokhipha kalula into enobuthi i-bisphenol A. Eminye imibiko yocwaningo ibonisa ukuthi i-bisphenol A ingabangela ukuphazamiseka kwe-endocrine. Umdlavuza, ukukhuluphala okubangelwa ukuphazamiseka kwe-metabolic, ukuthomba ngaphambi kwesikhathi ezinganeni, njll. kungase kuhlotshaniswe ne-bisphenol A. Amazwe amaningi, njengeCanada, avimbele ukungezwa kwe-bisphenol A emaphaketheni okudla ezinsukwini zokuqala. I-China iphinde yavala ukungenisa nokudayiswa kwamabhodlela ezingane e-PC ngo-2011.
Izinkomishi eziningi zamanzi epulasitiki emakethe zenziwe nge-PC. Uma ukhetha inkomishi yamanzi ye-PC, sicela uyithenge eziteshini ezivamile ukuze uqinisekise ukuthi ikhiqizwa ngokuhambisana nemithethonqubo. Uma unenketho, mina ngokwami angincomi ukuthenga inkomishi yamanzi ye-PC.
2.PP impahla
I-PP polypropylene ayinambala, ayinaphunga, ayinabo ubuthi, iyashintshashintsha, ayiqukethe i-bisphenol A, futhi iyasha. Inephuzu lokuncibilika elingu-165°C futhi izothamba cishe ku-155°C. Izinga lokushisa elisetshenziswayo lingu-30 ~ 140°C. Izinkomishi ze-PP tableware ziwukuphela kwempahla yepulasitiki engasetshenziselwa ukushisisa i-microwave.
3.tritan impahla
I-Tritan futhi iyikhemikhali ye-polyester exazulula okuningi kokushiyeka kwamapulasitiki, okuhlanganisa ukuqina, amandla omthelela, nokuzinza kwe-hydrolytic. Ayizweli kumakhemikhali, isobala kakhulu, futhi ayiqukethe i-bisphenol A ku-PC. I-Tritan isiphumelele isitifiketi se-FDA (Isaziso Sothintana Nokudla (FCN) No.729) ye-US Food and Drug Administration futhi iyinto ekhethelwe imikhiqizo yezinsana e-Europe nase-United States.
4.PPSU impahla
I-PPSU (i-polyphenylsulfone) impahla iyi-amorphous thermoplastic, enokumelana nezinga lokushisa okuphezulu okungu-0℃~180℃, ingabamba amanzi ashisayo, inokungeneka okuphezulu kanye nokuzinza kwe-hydrolysis ephezulu, futhi iyimpahla yebhodlela yezingane ekwazi ukumelana nokuvala inzalo yesitimu. Iqukethe ikhemikhali ye-carcinogenic bisphenol A.
Ukuze uphephe wena nomndeni wakho, sicela uthenge amabhodlela amanzi eziteshini ezivamile futhi uhlole ngokucophelela ukwakheka kwezinto lapho uthenga.
Indlela yokuhlola inkomishi yamanzi yepulasitiki yezinga lokudla Izinkomishi zamanzi ezinjenge-“Big Belly Cup” kanye “Nebhakede lethani lethani” zonke zenziwe ngepulasitiki. Amaphutha ajwayelekile emikhiqizo yepulasitiki ami kanje:
1. Amaphuzu anhlobonhlobo (aqukethe ukungcola): anomumo wephoyinti, futhi ububanzi bawo obukhulu buwusayizi walo uma kulinganiswa.
2. Ama-Burrs: Amaqhuqhuva alayini emaphethelweni noma emigqeni ehlangene yezingxenye zepulasitiki (ngokuvamile okubangelwa ukubunjwa kabi).
3. I-Silver wire: Igesi elakheka ngesikhathi sokubumba ibangela ukuthi ingaphezulu lezingxenye zepulasitiki lishintshe umbala (ngokuvamile libe mhlophe). Iningi lala magesi
Umswakama kunhlaka. Amanye ama-resin amunca kalula umswakama, ngakho inqubo yokomisa kufanele yengezwe ngaphambi kokukhiqiza.
4. Amabhamuza: Izindawo ezingazodwa ngaphakathi kwepulasitiki zakha ama-protrusions ayindilinga ebusweni bayo.
5. Ukuguqulwa: Ukuguqulwa kwezingxenye zepulasitiki okubangelwa umehluko wangaphakathi wengcindezi noma ukupholisa okungekuhle ngesikhathi sokukhiqiza.
6. Ukwenza mhlophe kwe-ejection: Ukwenziwa mhlophe nokuguqulwa komkhiqizo oqediwe okubangelwa ukukhishwa esikhunjeni, ngokuvamile kwenzeka ngakolunye uhlangothi lwebhithi yokukhipha (indawo yesikhunta sikamama).
7. Ukushoda kwezinto ezibonakalayo: Ngenxa yokulimala kwesikhunta noma ezinye izizathu, umkhiqizo oqediwe ungase ungabi ne-saturated futhi ungabi nezinto ezibonakalayo.
8. Ukuphrinta okuphukile: Amabala amhlophe kumafonti aphrintiwe abangelwa ukungcola noma ezinye izizathu ngesikhathi sokuphrinta.
9. Ukuphrinta okungekho: Uma okuqukethwe okuphrintiwe kushoda imihuzuko noma amakhona, noma uma iphutha lokuphrinta ifonti likhulu kuno-0.3mm, kuthathwa njengokushoda kokuphrinta.
10. Umehluko wombala: ubhekisela kumbala wengxenye yangempela kanye nombala wesampula ogunyaziwe noma inombolo yombala eyeqa inani elamukelekayo.
11. Iphuzu lombala ofanayo: libhekisela endaweni lapho umbala useduze nombala wengxenye; ngaphandle kwalokho, iphoyinti lombala elihlukile.
12. Ukugeleza okugelezayo: Imigqa egelezayo yepulasitiki encibilikayo ishiywe esangweni ngenxa yokubunjwa.
13. Izimpawu zokushisela: Amamaki alayini akheka ngaphezulu kwengxenye ngenxa yokuhlangana kwemifudlana yepulasitiki encibilikisiwe emibili noma ngaphezulu.
14. Igebe Lomhlangano: Ngaphezu kwegebe elishiwo ekwakhiweni, igebe elibangelwa ukuhlanganiswa kwezingxenye ezimbili.
15. Imihuzuko emihle: imihuzuko engaphezulu noma amamaki angenawo ukujula (ngokuvamile okubangelwa ukusebenza ngezandla).
16. Imihuzuko eqinile: Imihuzuko yomugqa ejulile ebusweni bezingxenye ezibangelwa izinto eziqinile noma izinto ezicijile (ngokuvamile okubangelwa ukusebenza ngezandla).
17. I-dent and shrinkage: Kunezimpawu zama-dent ebusweni bengxenye noma ubukhulu buncane kunosayizi womklamo (ngokuvamile okubangelwa ukubunjwa okungalungile).
18. Ukuhlukaniswa kombala: Ekwenziweni kwepulasitiki, amapheshana noma amachashazi amamaki ombala avela endaweni yokugeleza (ngokuvamile okubangelwa ukwengezwa kwezinto ezigaywe kabusha).
19. Okungabonakali: kusho ukuthi iziphambeko ezinobubanzi obungaphansi kuka-0.03mm azibonakali, ngaphandle kwendawo ekhanyelayo ye-LENS (ngokuya ngebanga lokutholwa elishiwo engxenyeni ngayinye yezinto).
20. Iqhubu: okubangelwa indawo yomkhiqizo noma unqenqema lokushaywa into eqinile.
