ukubaluleka kwamanzi
Amanzi ngumthombo wobomi. Amanzi anokukhuthaza umetabolism womntu, ancede ukubila, kwaye alawule ubushushu bomzimba. Ukusela amanzi kuye kwaba ngumkhwa ophilayo ebantwini. Kwiminyaka yakutshanje, iikomityi zamanzi bezisoloko zisenza izinto ezintsha, njengendebe yosaziwayo kwi-Intanethi "Indebe enkulu yeBelly" kunye ne "Ton Bucket" edumileyo. I "Big Belly Cup" ithandwa ngabantwana kunye nolutsha ngenxa yesimo sayo esihle, ngelixa ukuveliswa kwe "Ton-ton Bucket" kukuba ibhotile iphawulwe ngexesha kunye nezikali zomthamo wamanzi okusela ukukhumbuza abantu ukuba basele amanzi. ixesha. Njengesixhobo esibalulekileyo samanzi okusela, kufuneka ukhethe njani xa uthenga?
Izinto eziphambili zeekomityi zamanzi zebakala lokutya
Xa kuthengwa indebe yamanzi, into ebaluleke kakhulu kukujonga izinto zayo, ezibandakanya ukhuseleko lwendebe yonke yamanzi. Kukho iintlobo ezine eziphambili zezinto eziqhelekileyo zeplastiki kwimarike: i-PC (i-polycarbonate), i-PP (i-polypropylene), i-tritan (i-Tritan Copolyester copolyester), kunye ne-PPSU (i-polyphenylsulfone).
1. Izinto zePC
I-PC ngokwayo ayinayo inetyhefu, kodwa izinto ze-PC (i-polycarbonate) azichasananga nokushisa okuphezulu. Ukuba ishushu okanye ibekwe kwindawo ene-acidic okanye i-alkaline, iya kukhulula ngokulula into enobuthi i-bisphenol A. Ezinye iingxelo zophando zibonisa ukuba i-bisphenol A inokubangela ukuphazamiseka kwe-endocrine. Umhlaza, ukutyeba okubangelwa kukuphazamiseka kwe-metabolic, ukufikisa kwangaphambi kwexesha kubantwana, njl. I-China ikwayekile ukungeniswa kunye nokuthengiswa kweebhotile zePC zabantwana ngo-2011.
Iikomityi ezininzi zamanzi zeplastiki kwimarike zenziwe ngePC. Ukuba ukhetha ikomityi yamanzi yePC, nceda uyithenge kwiitshaneli eziqhelekileyo ukuze uqinisekise ukuba iveliswa ngokuhambelana nemimiselo. Ukuba unokhetho, mna ngokwam andikucebisi ukuthenga ikomityi yamanzi yePC.
Izinto ze-2.PP
I-PP i-polypropylene ayinambala, ayinavumba, ayinayo ityhefu, i-translucent, ayinayo i-bisphenol A, kwaye iyatsha. Inendawo yokunyibilika eyi-165°C kwaye iyakuthamba malunga ne-155°C. Uluhlu lobushushu bokusetyenziswa yi -30 ~ 140 ° C. Iikomityi zetafile zePP zikwakuphela kwemathiriyeli yeplastiki enokusetyenziselwa ukufudumeza i-microwave.
3.izinto zetritan
I-Tritan ikwayikhemikhali yepolyester esombulula uninzi lweentsilelo zeplastiki, kubandakanya ukuqina, amandla empembelelo, kunye nokuzinza kwe-hydrolytic. Ayinyangeki ngamachiza, ayifihli kakhulu, kwaye ayinayo i-bisphenol A kwiPC. I-Tritan iphumelele isatifikethi se-FDA (Isaziso soQhagamshelwano lokuTya (FCN) No.729) ye-US Food and Drug Administration kwaye sisixhobo esichongiweyo kwiimveliso zeentsana eYurophu nase-United States.
Izinto ze-4.PPSU
Izinto ze-PPSU (i-polyphenylsulfone) yi-amorphous thermoplastic, enokumelana nokushisa okuphezulu kwe-0℃ ~ 180 ℃, inokubamba amanzi ashushu, inokungena okuphezulu kunye nokuzinza okuphezulu kwe-hydrolysis, kwaye yimpahla yebhotile yabantwana enokumelana nokutshatyalaliswa komphunga. Iqulethe i-carcinogenic chemical bisphenol A.
Ukukhusela wena kunye nosapho lwakho, nceda uthenge iibhotile zamanzi kwiitshaneli eziqhelekileyo kwaye uhlolisise ngokucophelela ukubunjwa kwezinto eziphathekayo xa uthenga.
Indlela yokuhlola ikomityi yamanzi yeplastiki yodidi lokutya Iikomityi zamanzi ezifana ne "Big Belly Cup" kunye "neBhakethi yeetoni zeetoni" zonke zenziwe ngeplastiki. Iziphene eziqhelekileyo zeemveliso zeplastiki zezi zilandelayo:
1. Amanqaku ahlukeneyo (aqulethe ukungcola): anemilo yenqaku, kwaye ubukhulu bayo bobukhulu bubukhulu bayo xa kulinganiswa.
2. IiBurrs: Amaqhuqhuva emigca emiphethweni okanye kwimigca edibeneyo yamalungu eplastiki (adla ngokubangelwa kukubunjwa kakubi).
3. Ucingo lwesilivere: Irhasi eyenziwe ngexesha lokubumba ibangela ukuba umphezulu wamalungu eplastiki ajike umbala (ngokuqhelekileyo abe mhlophe). Uninzi lwezi gesi
Kukufuma kwintlaka. Ezinye iirasi zithatha ngokulula ukufuma, ngoko inkqubo yokomisa kufuneka yongezwe ngaphambi kokuvelisa.
4. Amaqamza: Iindawo ezikwanti ngaphakathi kweplastiki zenza iiprotrusions ezingqukuva kumphezulu wayo.
5. Ukuguqulwa: Ukuguqulwa kwamalungu eplastiki okubangelwa ukungafani koxinzelelo lwangaphakathi okanye ukupholisa kakubi ngexesha lokuvelisa.
6. I-ejection whitening: Ubumhlophe kunye nokuguqulwa kwemveliso egqityiweyo ebangelwa ukukhutshwa kwi-mold, ngokuqhelekileyo kwenzeka kwelinye isiphelo se-ejection bit (umama ukungunda komhlaba).
7. Ukunqongophala kwezinto eziphathekayo: Ngenxa yomonakalo kwisikhunta okanye ezinye izizathu, imveliso egqityiweyo inokuthi ingabikho kwaye ingabikho.
8. Ukuprintwa okuphukile: Amabala amhlophe kwiifonti eziprintiweyo ezibangelwa ukungcola okanye ezinye izizathu ngexesha lokushicilela.
9. Ushicilelo olungekhoyo: Ukuba umxholo oprintiweyo ulahlekile imikrwelo okanye iikona, okanye ukuba isiphene sefonti yoshicilelo sikhulu kuno-0.3mm, sikwathathwa njengento engekhoyo ukuprinta.
10. Umahluko wombala: ubhekisa kumbala wenxalenye yokwenyani kunye nombala wesampula ovunyiweyo okanye inombolo yombala edlula ixabiso elamkelekileyo.
11. Indawo yombala ofanayo: ibhekisa kwindawo apho umbala usondele kumbala wenxalenye; ngenye indlela, yindawo eyahlukileyo yombala.
12. Imigca equkuqelayo: Imitya yeplastiki enyibilikayo eshushu ishiywe esangweni ngenxa yokubunjwa.
13. Amanqaku e-Weld: Amanqaku emigca enziwe kumphezulu wenxalenye ngenxa yokudibana kwemijelo yeplastiki etyhidiweyo emibini nangaphezulu.
14. Isikhewu seNdibano: Ukongeza kwisithuba esichazwe kuyilo, isithuba esibangelwa kukudityaniswa kwamacandelo amabini.
15. Imikrwelo emihle: imikrwelo yomhlaba okanye amanqaku angenabunzulu (ngokuqhelekileyo abangelwa kukusebenza kwezandla).
16. Imikrwelo enzima: Imikrwelo enzulu yomgca kumphezulu wamalungu abangelwa zizinto eziqinileyo okanye izinto ezibukhali (ezidla ngokubangelwa yimisebenzi yezandla).
17. I-Dent kunye ne-shrinkage: Kukho iimpawu ze-dents ebusweni benxalenye okanye ubukhulu buncinci kunobukhulu bokuyila (ngokuqhelekileyo kubangelwa ukubunjwa kakubi).
18. Ukwahlula kombala: Kwimveliso yeplastiki, imichilo okanye amachaphaza ombala wamanqaku avela kwindawo yokuhamba (ngokuqhelekileyo kubangelwa ukongezwa kwezinto ezihlaziyiweyo).
19. Ezingabonakaliyo: kuthetha ukuba iziphene ezinobubanzi obungaphantsi kwe-0.03mm azibonakali, ngaphandle kwendawo ecacileyo ye-LENS (ngokomgama wokufumanisa ochazwe kwinxalenye nganye yezinto).
20. Iqhuma: libangelwa kukubethwa komphezulu wemveliso okanye kumphetho wento eqinileyo.
