Ukuphumelela kwiMelamine Tableware enganyangekiyo kubushushu obuphezulu: Ingxelo yoVavanyo lokuhambelana kwezixhobo zasekhitshini eziphambili kwiivenkile zokutyela ezithengisa izinto ezahlukeneyo

Iqela lezazinzulu kunye neengcali zoshishino liphuhlise izitya ze-melamine ezingatshisi kakhulu, eziqinisekiswe ngovavanyo olupheleleyo lokuhambelana nezixhobo zasekhitshini eziqhelekileyo. Le ngxelo iveza iziphumo eziphambili, igxininisa impumelelo kunye neziphumo kwimisebenzi yeevenkile zokutyela.1. Imvelaphi kunye nokubaluleka​

Izitya zesidlo ze-melamine zemveli, ezixabisa ukuqina nokufikeleleka lula, ziyasilela ngaphaya kwe-120°C—ziyingxaki kwiikhitshi eziphakathi ezisebenzisa izitya zokuhlamba izitya ezishushu kakhulu, izibulali-zintsholongwane zomphunga, kunye nee-oveni. Oku kubangela ukugoba, ukutshintsha kombala, ukukhutshwa kwezinto ezinobungozi, iingozi zokhuseleko, kunye neendleko eziphezulu zokutshintshwa.​

Ezi tafile zintsha zijongana nale ngxaki ngokusebenzisa izixhobo ezilungisiweyo kunye nokuveliswa, ezimelana nobushushu obufikelela kwi-180°C. Ukuqinisekiswa ngempumelelo kuthembisa ukunciphisa iindleko, ukhuseleko oluphuculweyo, ukusebenza kakuhle okuphuculweyo, kunye neenkqubo ezilula ngokuphelisa izixhobo ezikhethekileyo zokupheka kumaqondo obushushu ahlukeneyo.

2. Imigangatho yoVavanyo, iiSampuli, kunye neNdlela yokusebenza

2.1 Imigangatho yoVavanyo​

Uvavanyo lulandele imigangatho yamazwe ngamazwe: ASTM C518-17, FDA 21 CFR Icandelo 177.1460, ISO 22000, kunye ne-NSF/ANSI 51, ukuqinisekisa iziphumo ezivunyiweyo nezithembekileyo zokumelana nobushushu, ukhuseleko, kunye nokuhambelana.​

2.2 Iisampulu zovavanyo​

Iisampulu zaziquka izinto ezintsha zemelamine ezishushu kakhulu: iipleyiti ze-intshi ezili-10, izitya ze-ounces ezili-16, izikhongozeli zokugcina iilitha, iitreyi ze-intshi ezili-18x12, kunye nezixhobo zokukhaba. Imelamine yendabuko eneempawu ezifanayo yayisebenza njengezilawuli. Zonke iisampulu zazintsha kwaye zingasetyenziswanga.

2.3 Indlela yoVavanyo​

Zenziwe kwikhitshi eliphakathi eliqikelelweyo elebhu eqinisekisiweyo, uvavanyo lusebenzise indlela ecwangcisiweyo yohlobo ngalunye lwesixhobo. Iisampulu zenziwe imijikelo eli-12 (nganye ilinganisa iveki enye yokusetyenziswa) kunye novavanyo lokutshintsha komzimba, ukuzinza kweekhemikhali, ukuthembeka kokusebenza, kunye nokuhambelana kwezixhobo.

3. Izixhobo zovavanyo kunye neziphumo​

3.1 Iivenkile zokuhlamba izitya zorhwebo​

Zisebenza kwi-60-71°C (ukuhlamba) kunye ne-82-90°C (ukuhlamba), iisampulu zahlala ixesha elide kwi-dishwasher ye-Hobart AM15V.

Imelamine eshushu kakhulu ayizange ijike, ayikrweli kakhulu, ayitshintshanga umbala ngesosi yetumato/ikhari, kwaye yamelana nokuhlamba ngama-88°C. Imelamine yendabuko yayijike ngama-30% emva kwemijikelo engama-50, yatshintsha umbala kakhulu ngemijikelo engama-30, kwaye yaqhekeka ngama-15% emva kwemijikelo eli-100.

3.2 Izibulali-ntsholongwane zomphunga​

Zisebenza kwi-121-134°C phantsi koxinzelelo, iisampulu zenziwe imijikelo engama-50 kwi-Tuttnauer 2540E sterilizer (imizuzu engama-30 kwi-121°C/15 psi).

I-melamine enobushushu obuphezulu ayibonisanga monakalo, ubunzima obuzinzileyo, kwaye akukho melamine/formaldehyde enokubonwa. I-melamine yendabuko yayinokugoba okukhulu emva kwemijikelo eli-10, idlula amanqanaba e-melamine akhuselekileyo ngama-40% ngemijikelo emi-5 (80% ngama-20), kwaye ikhupha amadyungudyungu/ixobuka kumphezulu.​
3.3 Ii-Ovens Ezishushu Kakhulu​

Iisampulu zigcinwe imijikelo engama-30 (imizuzu engama-30 kwi-180°C) kwi-oven yeVulcan VC5GD.

I-melamine enobushushu obuphezulu ayizange ibonakale ijikajika, iqhekeka, okanye itshintsha umbala, inokumelana okuhle kakhulu nobushushu kunye nokusasazwa kobushushu okufanayo. I-melamine yendabuko yajikajika kwangoko, yaqhekeka ngama-60% emva kwemijikelo emi-5, kwaye yajika yaba tyheli kakhulu ngemijikelo eli-10.​

3.4 Abacoci be-Ultrasonic​

Iisampulu zidlule kwimijikelo engama-50 (imizuzu eli-15 nganye) kwisicoci seBranson CPX3800.

I-melamine enobushushu obuphezulu ayibonisanga monakalo kwisakhiwo, ukugqitywa komphezulu okuqinileyo, kwaye akukho mingxunya. I-melamine yendabuko yayinokukhukuliseka okuncinci komphezulu kwimizobo eprintiweyo emva kwemijikelo engama-30 kwaye ifiphale kancinci.​

4. Ukuqina kunye noKhuseleko lwexesha elide​

4.1 Ukuqina Kwexesha Elide​

Emva kweenyanga ezi-6 zokusetyenziswa ngendlela yokulinganisa (ukuhlamba izitya, ukubulala iintsholongwane, kunye nokudibana kokutya okukumaqondo obushushu angama-95°C), i-melamine eshushu kakhulu ibonakalise ukukrwela okuncinci kuphela kunye nesakhiwo sayo esipheleleyo kunye nomsebenzi wayo. I-melamine yendabuko yayingafaneleki ukusetyenziswa ngama-70% ngenxa yokugoba, ukuqhekeka, okanye ukutshintsha kombala.​
4.2 Uvavanyo loKhuseleko​

Uvavanyo lokufuduka olusebenzisa izinto ezifana nokutya, uhlalutyo lwesinyithi esinzima, kunye novavanyo lokukhululwa kwe-formaldehyde/melamine lubonise onke amanqanaba angaphantsi kwemida ye-FDA/EU, okuqinisekisa ukhuseleko phantsi kweemeko ezinzima.

5. Iziphumo Ezisebenzayo​

5.1 Ukonga iindleko​

Ngobomi obude obuphindwe kathathu ukuya kane kunemelamine yendabuko, iitsheyini eziphakathi (iindawo ezingama-50) zinokonga imali
​
50,000−100,000 ngonyaka. Ukuhambelana kunciphisa iindleko zempahla ngokuphelisa izitya ezikhethekileyo.

5.2 Ukusebenza kakuhle​

Ukusetyenziswa ngokubanzi ukususela ekulungiseleleni ukuya ekuphakeni kunciphisa ukudluliselwa kokutya, kunciphisa ixesha kunye neengozi zongcoliseko. Ukuqina kunciphisa ixesha lokungasebenzi kwakhona.

5.3 Ukhuseleko lokutya kunye nokungaguquguquki kophawu​

Uzinzo luthintela ukukhutshwa okuyingozi ngexesha lokucoca umzimba kwaye lunciphisa ukukhula kweebhaktheriya. Inkangeleko ehambelanayo igcina umfanekiso wophawu kwiindawo ezahlukeneyo.

6. Izimvo zeengcali​

Umpheki uMaria Rodriguez uthe: “Ezi ziphumo zitshintsha umdlalo—izitya ezisebenza ukusuka kwisitya sokuhlamba izitya ukuya kwisixhobo sokucoca izitya zenza kube lula ukusebenza.” UJohn Chen wongezelela ngelithi: “Ukugcina ukhuseleko phantsi kwamaqondo obushushu aphezulu kuqinisekisa imigangatho ngelixa kuphucula ukusebenza kakuhle.” UGqr. Emily Wong uncome “impumelelo emangalisayo yefomyula enobungqina obuqinileyo bovavanyo.”

7. Isiphelo kunye neMbono​

Iziphumo zovavanyo ziqinisekisa ukuba izitya ezintsha ze-melamine ziyamelana neemeko zorhwebo ezinzima ngelixa zigcina ukhuseleko kunye nokusebenza kakuhle. Iingenelo ziquka iindleko eziphantsi, ukusebenza ngcono, ukhuseleko oluphuculweyo, kunye nokuhambelana kophawu.

Izicwangciso zexesha elizayo ziquka ukwandisa uluhlu lweemveliso kunye novavanyo oluqhubekayo lokuqina kwehlabathi lokwenyani. Olu tshintsho lubeka imigangatho emitsha yeetafile zeenkonzo zokutya, lubonelela ngeevenkile zokutyela ezithengiswayo ngendlela ekhuphisanayo ngokusebenza ngcono, iindleko eziphantsi, kunye nokhuseleko oluphuculweyo.​
