Njengoko ulwazi lwezempilo lwabantu luqhubeka lukhula, ukukhethwa kwezinto eziphathekayo kwiikomityi zamanzi kuye kwaba sisihloko esixhalabisa kakhulu. Izinto eziqhelekileyo zekomityi yamanzi kwiimarike ziquka iglasi, insimbi engenasici, iplastiki, njl. Phakathi kwazo, iikomityi zamanzi zeplastiki zithandwa kakhulu ngenxa yokukhanya kunye nokuqina. I-PC (i-polycarbonate) kunye ne-PP (i-polypropylene) zizinto ezimbini eziqhelekileyo zeplastiki. Kwiminyaka yakutshanje, iikomityi zamanzi ezenziwe ngePC + PP zezinto ezidibeneyo ziye zangena ngokuthe ngcembe kwimarike. Ke, ingaba iikomityi zamanzi ezenziwe ngePC+PP zikhuselekile? Eli nqaku liza kuqhuba uhlalutyo olucacileyo kwiinkalo ezininzi ezifana neempawu eziphathekayo, ukusetyenziswa kokhuseleko, kunye nemiphumo yempilo.
1. I-PC (polycarbonate) uhlalutyo lwezinto
1. Iimpawu zezinto eziphathekayo
• Ukukhanya okuphezulu: Izinto zePC zinokucaca kakuhle kwaye zikhangeleka zifana neglasi, kodwa zikhaphukhaphu ngobunzima.
• Uxhathiso olunamandla: Izinto zePC zinempembelelo ebalaseleyo yokuchasa kwaye akukho lula ukwaphula. Kufanelekile ukwenza iimveliso ezifuna amandla aphezulu.

• Ukuguquguquka: Le komityi yemathiriyeli edibeneyo yamanzi idla ngokuyilwa kunye nolwakhiwo oluphindwe kabini, kunye nomaleko ongaphakathi owenziwe ngemathiriyeli yePP kunye nomaleko wangaphandle owenziwe ngemathiriyeli yePC ukukhuthaza ukusebenza ngokubanzi kunye nokusetyenziswa kwamava ekomityi yamanzi.
2. Inkqubo yokuvelisa
• Itekhnoloji ehlanganisiweyo: I-PC + PP ibhotile yamanzi edibeneyo isebenzisa iteknoloji ephezulu yokudibanisa ukudibanisa izinto ezimbini ngenkqubo ethile yokuqinisekisa ukudibanisa okuqinileyo kunye nokuzinza phakathi kwezinto.
• Uqhagamshelo olungenamthungo: Ngoyilo lokungunda oluchanekileyo kunye nobuchwepheshe bokusetyenzwa, iileya zangaphakathi nangaphandle zekomityi yamanzi ziqhagamshelwe ngaphandle komthungo ukunqanda iingxaki zokusetyenziswa ezibangelwa kukwahlulwa kwezinto.
4. Uhlalutyo lokhuseleko lwePC + PP iikomityi zamanzi ezibonakalayo
1. Iziphumo zempilo
• Ukulawulwa kwengozi ye-BPA: Ekubeni izinto ze-PC zinokuba ne-BPA, xa ukhetha i-PC + PP yekomityi yamanzi edibeneyo, kufuneka ubeke ingqalelo ekukhetheni iimveliso ezibhalwe nge-logo ethi "BPA Free" (i-bisphenol A-free) ukuqinisekisa impilo kunye nokhuseleko lwabo.
• Isiqinisekiso semathiriyeli yePP: Imathiriyeli yePP ngokwayo ayinayo ityhefu, ayinancasa kwaye ayinazinto eziyingozi. Njengoko i-internal layer material, idibana ngokuthe ngqo namanzi kunye neziselo, ezinokunciphisa ngokufanelekileyo ingozi yempilo.
2. Ukumelana nobushushu
• Ukusetyenziswa kobushushu obuphezulu: I-PC + PP iikomityi zamanzi ezihlanganisiweyo zihlala zimelana namaqondo obushushu aphezulu, zifanelekile ukubamba amanzi ashushu kunye neziselo ezishushu, kwaye akulula ukuguqula okanye ukukhulula izinto ezinobungozi ngexesha lokusetyenziswa.
• Ukusetyenziswa kwii-oveni zemicrowave: Ngenxa yokuxhathisa ubushushu obulungileyo bezinto zePP, ezinye iikomityi zamanzi ezenziwe ngePC+PP izinto ezihlanganisiweyo zingasetyenziswa kwii-oveni zemicrowave, kodwa imiyalelo ethile kwimiyalelo yemveliso kufuneka ilandelwe ukunqanda ukufudumeza kumaqondo obushushu aphezulu. ixesha elide.
3. Ukuqina kunye nobomi benkonzo
• Ukuchasana kwempembelelo: Ukuxhatshazwa kwempembelelo ephezulu yezinto ze-PC kwenza ukuba ikomityi yamanzi ingakwazi ukuphuka ngexesha lokusetyenziswa kwemihla ngemihla, ukwandisa ukuqina kunye nobomi benkonzo yemveliso.
• Ukumelana neekhemikhali: Uzinzo oluhle lweekhemikhali zezinto zePP zenza ukuba ikomityi yamanzi ingabi namathuba okujongana neekhemikhali xa idibana neziselo ezine-asidi kunye ne-alkaline, igcina uzinzo kunye nokhuseleko lwemathiriyeli.
4. Ukucoca kunye nokugcinwa
• Ukucoca ngokulula: Iikomityi zamanzi ezenziwe nge-PC + PP izinto ezihlanganisiweyo ngokubanzi zinomgangatho ogudileyo, ongelula ukubambelela kumdaka kwaye kulula ukuwucoca. Kucetyiswa ukuba kusetyenziswe amanzi afudumeleyo kunye ne-detergent engathathi hlangothi yokucoca, kwaye ugweme ukusebenzisa izinto ezinzima ezifana neebhola zetsimbi ukukrazula.
• Ukuhlolwa rhoqo: Rhoqo jonga unxibelelwano phakathi ko maleko wangaphakathi nangaphandle webhotile yamanzi ukuqinisekisa ukuba akukho ukuxenga okanye ukwahlula. Ukuba kukho nakuphi na ukungaqhelekanga kufunyenwe, kufuneka kutshintshwe kwangethuba ukuqinisekisa ukusetyenziswa ngokukhuselekileyo.
5. Iingcebiso zokuthenga
1. Khetha uphawu oluqhelekileyo
• Isidima sophawu: Khetha iikomityi zamanzi ezihlanganisiweyo zePC+PP eziveliswe ziimpawu ezithembekileyo nabavelisi ukuqinisekisa umgangatho wemveliso kunye nokhuseleko.
• UPhawu lweSiqinisekiso: Khetha iimveliso eziqinisekisiweyo zodidi lokutya nezibhalwe “i-BPA yamahala” ilogo ukuqinisekisa ukuba azinazinto eziyingozi.
2. Jonga inkcazo yemveliso
• Imiyalelo yokusetyenziswa: Funda imiyalelo yemveliso ngononophelo ukuze uqonde uluhlu lokusetyenziswa, iqondo lobushushu elikwaziyo ukumelana nobushushu, iindlela zokucoca, njl.njl. yekomityi yamanzi ukuqinisekisa ukusetyenziswa okuchanekileyo.
