Loluphi uhlobo lweekomityi zamanzi zeplastiki ezingenakufaneleka? Nceda ubone:
Okokuqala, ileyibhile ayicacanga. Umhlobo oqhelekileyo wakubuza, ngaba awusoloko uwubeka kwindawo yokuqala umbandela? Kutheni ungazichaza ngokucacileyo namhlanje? Kukho iintlobo ezininzi zezinto zokuvelisa iikomityi zamanzi zeplastiki, ezinje: AS, PS, PP, PC, LDPE, PPSU, TRITAN, njl. Izinto zokuvelisa iikomityi zamanzi zeplastiki nazo ziyibakala lokutya. Ngaba ubhidekile? Basekwibanga lokutya. Kwakutheni ukuze inqaku langaphambili lomhleli likhankanye ukuba ezinye izinto ziyingozi? Ewe, oku kuhambelana nomba wokumakishwa okungacacanga. Ngenxa yokunqongophala kolwazi lwabathengi malunga nezixhobo zeplastiki, ngokukodwa banokuqonda okuncinci kwimixholo emele iisimboli zamanani ezinxantathu phantsi kweekomityi zamanzi zeplastiki.
Oku kubangela ukuba abathengi bacinge ukuba iikomityi zamanzi zeplastiki abazithengayo zikhuselekile kukutya, kodwa ngenxa yokusetyenziswa kakubi, iikomityi zamanzi zikhupha izinto ezinobungozi. Umzekelo: AS, PS, PC, LDPE kunye nezinye izinto azikwazi ukumelana namaqondo aphezulu. Izinto eziphathekayo ezinamaqondo okushisa kwamanzi angaphezu kwe-70 ° C ziya kukhulula i-bisphenolamine (bisphenol A). Abahlobo banokukhangela ngokuzithemba i-bisphenolamine kwi-intanethi. Izinto ezifana ne-PP, i-PPSU, kunye ne-TRITAN inokumelana nokushisa okuphezulu kwaye ayikhuphe i-bisphenolamine. Ke ngoko, xa abathengi bengazi iimfuno zokusetyenziswa kwezixhobo, owona mbuzo uxhaphakileyo abathengi abaninzi bawubuzayo kukuba ingaba isikhongozeli samanzi ashushu siya konakala. I-Deformation lutshintsho kuphela kwimilo kwaye ukukhululwa kwezinto ezinobungozi zizinto ezimbini ezahlukeneyo.
Uninzi lweekomityi zamanzi zeplastiki ezithengiswa kwimarike ziya kuba nesimboli samanani unxantathu ezantsi. Abanye abavelisi abanoxanduva baya kongeza igama lempahla ecaleni kwesimboli yonxantathu wamanani, njengale: PP, njl njl. Nangona kunjalo, kusekho iikomityi zamanzi zeplastiki eziveliswe ngabarhwebi abanganyanisekanga abangenazo iisimboli okanye baneempawu ezingalunganga. Ke ngoko, ndicinga ukuba ukuleyibhile okungacacanga yeyona nto iphambili. Kwangaxeshanye, ndikwacebisa ukuba wonke umenzi wekomityi yamanzi eplastiki aqwalasele impilo yabathengi. Ukongeza kwisimboli sikanxantathu wamanani kunye negama lezinto eziphathekayo, kukho iileyibhile ezichasene nobushushu kunye neelebhile ezikhupha izinto ezinobungozi. Ingcebiso, ukuze abathengi bakwazi ukuthenga iikomityi zamanzi zeplastiki ezibafaneleyo ngokwemikhwa yabo yokuthenga.
Okwesibini, izinto eziphathekayo. Le nto sithetha ngayo apha ayilona uhlobo lwezinto eziphathekayo, kodwa umgangatho wezinto eziphathekayo ngokwazo. Kungakhathaliseki ukuba luhlobo luni lwezixhobo zeplastiki ezisetyenziselwa ukutya, kukho ukungafani phakathi kwezinto ezintsha, izinto ezindala kunye nezinto ezihlaziyiweyo. Ukubengezela kunye nesiphumo seemveliso ezisebenzisa izinto ezintsha azinakuphunyezwa ngokusebenzisa izinto ezindala okanye izinto ezihlaziyiweyo. Izinto ezindala kunye nezinto ezisetyenzisiweyo zingasetyenziswa phantsi kwemeko yolawulo olusemgangathweni kunye nolawulo olungqongqo lwekhwalithi ngaphandle kokungcola. Oku kukwangqamene noluvo lokuphinda kusetyenziswe izinto ezihambelana nokusingqongileyo. Nangona kunjalo, kukho abathengisi abanganyanisekanga abasebenzisa izinto ezindala okanye izinto ezisetyenzisiweyo ngaphandle kwemigangatho, kwaye indawo yokugcina imbi kakhulu. Bade batyumze iziphelo kunye nemisila yeemveliso zangaphambili kwaye bazisebenzise njengezinto ezihlaziyiweyo. Nceda ujonge ngononophelo xa uthenga iikomityi zamanzi zeplastiki. Ukuba ufumanisa ukuba ezinye iikomityi zamanzi zeplastiki zinokungcola okuguquguqukayo okanye inani elikhulu lokungcola, kufuneka unikezele ngokukhawuleza kwaye ungathengi iikomityi zamanzi ezinjalo.
Okwesithathu, umsebenzi wendebe yamanzi. Xa uthengela indebe yamanzi eplastiki, kufuneka uhlolisise ngokucophelela izixhobo ezisebenzayo eziza kunye nendebe yamanzi, khangela ukuba imisebenzi iphelile, kwaye uqinisekise ukuba izixhobo azonakaliswanga okanye ziwile. Xa uthenga ikomityi yamanzi yeplastiki ngaxeshanye, kungcono ukuyisebenzisa ngokwemikhwa yakho yokusetyenziswa kunye nemisebenzi yekomityi yamanzi. Jonga ukuba iimpumlo zakho ziqhuma xa usela amanzi, nokuba isithuba esisemqhelweni kulula ukusibamba ngesandla, njl njl. Umhleli uthethe ngokutywinwa kumanqaku amaninzi. Ukuba ibhotile yamanzi oyithengayo ayivaleki kakuhle, le yingxaki emandla.
Ekugqibeleni, ukumelana nobushushu. Umhleli ukhankanyile ngaphambili ukuba ukumelana nokushisa kweekomityi zamanzi zeplastiki kuyahluka, kwaye ezinye izinto ziya kukhupha izinto ezinobungozi ngenxa yokushisa okuphezulu. Ngoko ke, xa uthengela iikomityi zamanzi zeplastiki, kufuneka uqonde ngokucophelela izinto zokuvelisa kunye neempawu zezixhobo. Ndingathanda ukukhumbuza wonke umntu olapha ukuba ezinye iimveliso zichaza iplastiki njengempahla yepolymer, eneneni i-gimmick ekubhaleni. Phakathi kwazo, iikomityi zamanzi ezenziwe ngezinto ze-AS azikwazi ukumelana nobushushu obuphezulu, kwaye azikwazi ukumelana nokuhluka kweqondo lokushisa. Amanzi ashushu aphezulu okanye amanzi e-ice aya kubangela ukuba izinto eziphathekayo ziqhekeke.
