Xa kuthengwa iziselo, uya kufumanisa ukuba kukho isimboli sesetyhula esingunxantathu kunye nenombolo emazantsi ebhotile nganye. Ke indlela yokutolika intsingiselo yeesimboli eziphinda zisetyenziswe unxantathu kunye namanani emazantsi eebhotile zeplastiki?
“Unxantathu” luphawu lweplastiki yokurisayikilisha. ilizwe lam lisebenzisa isimboli engunxantathu njengophawu lokurisayikilishwa kweplastiki
Athetha ntoni amanani angaphakathi kunxantathu osemazantsi ekomityi yeplastiki?
Olu luphawu lokurisayikilishwa kokusingqongileyo kweplastiki. I-PC sisishunqulelo se-polycarbonate, kwaye i-7 ithetha ukuba ayikho iplastiki eqhelekileyo. Ekubeni i-polycarbonate ayiwele kuluhlu lwezinto ezingentla ze-1-6, inombolo ephawulwe phakathi konxantathu wesibonakaliso sokubuyisela kwakhona i-7. Ngelo xesha, ukwenzela ukuba kube lula ukuhlenga ngexesha lokuphinda kusetyenziswe, igama lezinto eziphathekayo zePC ziphawulwe. ecaleni kophawu lokurisayikilishwa.
1. “Hayi. 1″ I-PETE: iibhotile zamanzi ezimbiwa, iibhotile zesiselo sekhabhoni, kunye neebhotile zesiselo akufuneki ziphinde zisetyenziswe ukuze kugcinwe amanzi ashushu. Ukusetyenziswa: Imelana nobushushu ukuya kuma-70°C. Kufanelekile kuphela ukubamba iziselo ezifudumeleyo okanye ezibandayo. Iyakonakala ngokulula xa izaliswe lulwelo olunobushushu obuphezulu okanye ishushu, kwaye izinto eziyingozi kumzimba womntu zinokunyibilika. Ngaphezu koko, izazinzulu ziye zafumanisa ukuba emva kweenyanga ezili-10 zokusetyenziswa, iPlastiki No. 1 inokukhupha i-carcinogen DEHP, enetyhefu kumasende.

Ke ngoko, ufuna ukunqanda ukupakisha ukutya okushushu kwiibhokisi ze-snack.
7. “Hayi. 7″ PC: Ezinye iindidi: iiketile, iikomityi, iibhotile zabantwana
Yeyiphi imathiriyeli eyona ikhuselekileyo kwiikomityi zamanzi zeplastiki?
No. 5 PP polypropylene iplastiki yamanzi indebe ukhuseleko
Ngokuqhelekileyo zisetyenziswa ziibhotile zobisi lwesoya, iibhotile zeyogathi, iibhotile zesiselo sejusi, kunye neebhokisi zesidlo sasemini kwimicrowave. Ngendawo yokunyibilika ukuya kwi-167 ° C, yiyo kuphela ibhokisi yeplastiki enokufakwa kwi-oven microwave kwaye ingaphinda isetyenziswe emva kokucoca ngononophelo.
Kufuneka kuqatshelwe ukuba kwezinye iibhokisi ze-microwave zesidlo sasemini, ibhokisi lebhokisi lenziwe ngeNombolo ye-5 PP, kodwa isiciko senziwe ngeNombolo ye-1 PE. Kuba i-PE ayikwazi ukumelana namaqondo obushushu aphezulu, ayinakufakwa kwi-oven microwave kunye nomzimba webhokisi. Nika ingqalelo ekhethekileyo kwiPP ecacileyo, engeyiyo i-microwave PP, ngoko ke iimveliso ezenziwe ngayo azikwazi ukufakwa ngokuthe ngqo kwi-oven microwave.
Ukuba uhlala usela amanzi ashushu, unokukhetha iPPSU kwinqanaba eliphezulu. I-PA12, esetyenziswa ngokuqhelekileyo kumaqondo obushushu angaphezu kwe-120 degrees, inokumelana nokuguga okunamandla. Isiphelo esisezantsi yiPP, enokumelana namaqondo okushisa angaphezu kwe-100 degrees. Nangona kunjalo, ubushushu obuqhelekileyo bujikeleze i-80 degrees, ekulula ukuguga kwaye ingabizi. Uluhlu oluphakathi luyi-PCTG enganyangekiyo kwiqondo lokushisa, enamandla amakhulu kunye nokumelana nokushisa okungcono kunePP. Ukuba usela amanzi abandayo kuphela, i-PC ineendleko eziphezulu, kodwa amanzi ashushu aya kuyikhulula ngokulula i-BPA.
Iikomityi ezenziwe nge-PP zinokumelana nokushisa okulungileyo, kunye nendawo yokunyibilika kwe-170 ℃ ~ 172 ℃, kunye neepropati zekhemikhali ezizinzileyo. Ukongeza ekungcolisweni yi-asidi yesulfuric egxininisiweyo kunye ne-nitric acid egxininisiweyo, azinzile kwezinye ii-reagents ezahlukeneyo zemichiza. Kodwa ingxaki ngeekomityi zeplastiki eziqhelekileyo zixhaphake. Iplastiki yimathiriyeli yeekhemikhali zepolymer. Xa ikomityi yeplastiki isetyenziselwa ukuzalisa amanzi ashushu okanye amanzi abilayo, i-polymer iya kukhawuleza kwaye inyibilike emanzini, eya kuba yingozi kwimpilo yabantu emva kokusela.
Kule mihla, ilizwe linokubeka iliso okungqongqo kakhulu kukhuseleko lokutya, ke iikomityi zeplastiki ezithengiswa emarikeni zikhuselekile. Unokujonga kwakhona kwilogo. Kukho uphawu emazantsi ekomityi yeplastiki, yona inani elikunxantathu omncinci. Eyona nto iqhelekileyo "05" , ebonisa ukuba izinto zendebe yiPP (polypropylene). Ukuba ufumanisa ukuba kunzima kakhulu, ungaphinda uthenge i-brand, njenge-Tupperware, engoyikiyo ukuwa kunye nokutywinwa okulungileyo.
Ngokwethiyori, nje ukuba i-bisphenol A i-100% iguqulelwe kwisakhiwo seplastiki ngexesha lokuveliswa kwePC, oko kuthetha ukuba imveliso ayinayo i-bisphenol A konke konke, kungabikho ukuyikhupha. Nangona kunjalo, ukuba inani elincinci le-bisphenol A aliguqulwa libe kwisakhiwo seplastiki yePC, inokukhutshwa kwaye ifake ukutya okanye iziselo. Ngoko ke, lumka xa usebenzisa esi singxobo seplastiki. Ukuphakama kweqondo lokushisa, i-bisphenol A eninzi ihleli kwi-PC iya kukhutshwa, kwaye ngokukhawuleza iya kukhutshwa. Ngoko ke, iibhotile zamanzi zePC akufanele zisetyenziswe ukubamba amanzi ashushu.
Ukusela amanzi kwiikomityi ezi-3 kunokubangela umhlaza
1. Iikomityi zephepha ezilahlwayo zinokuba ne-carcinogens

Ukuba ubushushu bamanzi buphezulu kakhulu, bunokubangela ukuba ikomityi igqabhuke, ngoko zama ukunqanda ukubamba amanzi ashushu.
2. Iikomityi ze-ceramic ezingavezwanga kunye nedayiwe
Ukhetho lokuqala lwamanzi okusela yindebe ye-ceramic engenambala we-glaze kunye nokudaya, ngokukodwa udonga lwangaphakathi kufuneka lungabi mbala. Ayisiyiyo kuphela into ekhuselekileyo, inokumelana namaqondo okushisa aphezulu, kwaye ikwanayo nefuthe elihle lokufakelwa kwe-thermal. Lukhetho olulungileyo lokusela amanzi ashushu okanye iti. Ngoko ke, ngenxa yempilo, kufuneka ukhethe ikomityi efanelekileyo yamanzi yokusela amanzi. Yilumkele ikomityi yamanzi ebangela iingozi zezifo.
Isikhumbuzo esifudumeleyo
Kungcono ukuba ikomityi inokucocwa ngoko nangoko emva kokusetyenziswa ngakunye. Ukuba inzima kakhulu, kufuneka icocwe ubuncinane kanye ngosuku. Unokuyihlamba ngaphambi kokuba ulale ebusuku uze womise. Xa uhlambulula indebe, akufanele uhlambulule kuphela umlomo wendebe, kodwa kunye nezantsi kunye nodonga lwendebe. Ngokukodwa ngaphantsi kwendebe, engacocwanga rhoqo, inokuqokelela ezininzi iibhaktheriya kunye nokungcola.
Abahlobo basetyhini bayakhunjuzwa ngokukodwa ukuba i-lipstick ayinayo izithako zeekhemikhali kuphela, kodwa iphinda ithathe izinto ezinobungozi kunye ne-pathogens emoyeni. Xa usela amanzi, izinto eziyingozi ziya kuziswa emzimbeni, ngoko ke i-lipstick eseleyo emlonyeni wendebe kufuneka icocwe. Xa ucoca ikomityi, ukuyihlamba nje ngamanzi akwanelanga, kungcono ukuyixuba ngebrashi.
Ukongezelela, ekubeni inxalenye ebalulekileyo ye-dishwashing liquid yi-chemical synthesis, kufuneka isetyenziswe ngokuqaphela kwaye ihlanjululwe ngamanzi acocekileyo. Ukucoca ikomityi edyojwe namafutha amaninzi, ubumdaka, okanye ibala leti, cofa intlama yamazinyo kwibrashi kwaye uyihlikihle ubuye naphambili ngaphakathi kwekomityi. Ekubeni intlama yamazinyo iqulethe zombini i-detergent kunye ne-arhente ehle kakhulu yokukhuhlana, kulula ukusula izinto ezishiyekileyo ngaphandle kokonakalisa umzimba wekomityi.
Iikomityi zichaphazeleka ngumbane ongatshintshiyo ovela kwiikhompyuter, i-chassis, njl., kwaye ziya kutsala uthuli oluninzi, iibhaktheriya kunye neentsholongwane eziya kuchaphazela impilo yakho ngokuhamba kwexesha. Ngenxa yesi sizathu, iingcali zicebisa ukuba kukulungele ukubeka isiciko kwindebe kwaye uyigcine kude neekhomputha kunye nezinye izixhobo zombane. Kufuneka kwakhona ugcine ukujikeleza komoya wangaphakathi kunye neefestile ezivulekileyo zokungenisa umoya ukuze uvumele uthuli luhambe nomoya.
