Ukuba khona kokungcola emaphaketheni eqhwa kuncike kakhulu ezintweni zawo kanye nokusetshenziswa kwawo.Kwezinye izimo, uma umsebenzi noma inqubo yokukhiqiza yephakethe leqhwa ingahlangabezani namazinga okuphepha kokudla, kungase kube nezinkinga zokungcola.Nazi ezinye izinto ezibalulekile zokucatshangelwa:
1. Ukwakheka kwamakhemikhali:
-Amanye amaphakethe eqhwa ekhwalithi ephansi angase abe namakhemikhali ayingozi njenge-benzene ne-phthalates (i-plasticizer esetshenziswa kakhulu), okungaba yingozi empilweni.Lawa makhemikhali angase angene ekudleni ngesikhathi sokusetshenziswa, ikakhulukazi ezindaweni ezishisa kakhulu.
2. Ukulimala nokuvuza:
-Uma isikhwama seqhwa sonakalisiwe noma sivuza ngesikhathi sokusetshenziswa, ijeli noma uketshezi olungaphakathi kungase kuhlangane nokudla noma iziphuzo.Nakuba izigcwalisi eziningi zezikhwama zeqhwa zingenabo ubuthi (njengejeli ye-polymer noma isixazululo saline), ukuthintana okuqondile namanje akunconywa.
3. Isitifiketi somkhiqizo:
-Uma ukhetha iphakethe leqhwa, hlola isitifiketi sokuphepha kokudla, njengokuvunyelwa kwe-FDA.Lezi zitifiketi zibonisa ukuthi impahla yephakethe yeqhwa iphephile futhi ifanele ukuthintana nokudla.
4. Ukusetshenziswa nokugcinwa okulungile:
-Qinisekisa ukuhlanzeka kwamaphakethe eqhwa ngaphambi nangemuva kokuwasebenzisa, futhi uwagcine ngendlela efanele.Gwema ukuhlalisana nezinto ezicijile ukuze uvimbele umonakalo.
-Uma usebenzisa i-ice pack, kungcono ukuyibeka esikhwameni esingangeni manzi noma ukuyisonga ngethawula ukuze ugweme ukuthintana ngqo nokudla.
5. Izindaba zemvelo:
-Uma kucatshangelwa ukuvikelwa kwemvelo, amaphakethe eqhwa angaphinda asetshenziswe, futhi kufanele kuqashelwe izindlela zokugaywa kabusha nezindlela zokulahla amaphakethe eqhwa ukuze kuncishiswe ukungcoliswa kwemvelo.
Ngamafuphi, ukukhetha amaphakethe eqhwa ekhwalithi ephezulu futhi aqinisekiswe ngokufanelekile, nokusebenzisa nokuyigcina ngendlela efanele, kunganciphisa ubungozi bokungcola.Uma kukhona ukukhathazeka okukhethekile kokuphepha, ungaba nokuqonda okuningiliziwe kwempahla yomkhiqizo kanye nokubuyekezwa komsebenzisi ngaphambi kokuthenga.
Izingxenye eziyinhloko zamaphakethe eqhwa aqandisiwe
Amaphakethe eqhwa afakwe esiqandisini ngokuvamile akhiwa ngezinto ezimbalwa ezibalulekile okuhloswe ngazo ukuhlinzeka nge-insulation enhle nokuqina okwanele.Izinto ezibalulekile zifaka:
1. Izinto zesendlalelo sangaphandle:
-Inayiloni: Ingasindi futhi ihlala isikhathi eside, ijwayele ukusetshenziswa kungqimba lwangaphandle lwamaphakethe eqhwa ekhwalithi ephezulu.Inayiloni inokumelana nokugqokwa okuhle kanye nokumelana nokukhala.
-I-Polyester: Enye into esetshenziswa kakhulu isendlalelo sangaphandle, eshibhe kancane kunenayiloni, futhi inokuqina okuhle nokumelana nokukhala.
-Vinyl: Ifanele izinhlelo zokusebenza ezidinga ukuvinjelwa kwamanzi noma okulula ukuzihlanza izindawo.
2. Izinto zokuvikela ukushisa:
-I-Polyurethane Foam: iyinto evame kakhulu yokuvikela i-insulating, futhi isetshenziswa kabanzi ezikhwameni zeqhwa eziqandisiwe ngenxa yokusebenza kwayo okuhle kakhulu kokushisa okushisayo kanye nezici ezingasindi.
Igwebu le-Polystyrene (EPS): eyaziwa nangokuthi i-styrofoam, le nto isetshenziswa kakhulu kumabhokisi abandayo aphathwayo kanye nezinye izixazululo zesikhathi esisodwa zokugcina ezibandayo.
3. Izinto zomugqa wangaphakathi:
-I-aluminium foil noma ifilimu eyenziwe nge-metalized: evame ukusetshenziswa njengento yolayini ukusiza ukukhombisa ukushisa nokugcina izinga lokushisa langaphakathi.
-Ibanga lokudla i-PEVA (i-polyethylene vinyl acetate): Izinto zepulasitiki ezingenabuthi ezivame ukusetshenziselwa ungqimba lwangaphakathi lwezikhwama zeqhwa ezithintana ngqo nokudla, futhi zithandwa kakhulu ngoba aziqukethe i-PVC.
4. Isigcwalisi:
-Isikhwama seGel: isikhwama esiqukethe ijeli ekhethekile, engagcina umphumela wokupholisa isikhathi eside ngemuva kokuqandisa.Ijeli ngokuvamile yenziwa ngokuxuba amanzi ne-polymer (njenge-polyacrylamide), ngezinye izikhathi i-preservative kanye ne-antifreeze yengezwa ukuze kuthuthukiswe ukusebenza.
-Amanzi anosawoti noma ezinye izixazululo: Amanye amaphakethe eqhwa alula angase abe namanzi anosawoti kuphela, anephuzu lokuqandisa eliphansi kunamanzi ahlanzekile futhi anganikeza isikhathi eside sokupholisa ngesikhathi sokuqandisa.
Lapho ukhetha isikhwama seqhwa esifanele esiqandisiwe, kufanele ucabangele ukuthi impahla yaso iyahlangabezana yini nezidingo zakho ezithile, ikakhulukazi ukuthi idinga isitifiketi sokuphepha kokudla, nokuthi isikhwama seqhwa sidinga ukuhlanzwa njalo noma ukusetshenziswa ezindaweni ezithile.
Izingxenye eziyinhloko zamaphakethe eqhwa afriziwe
Iphakethe leqhwa eliqandisiwe ngokuvamile liqukethe izingxenye eziyinhloko ezilandelayo, ngayinye enemisebenzi ethile yokuqinisekisa ukuthi iphakethe leqhwa eliqandisiwe ligcina izinga lokushisa eliphansi ngempumelelo:
1. Izinto zesendlalelo sangaphandle:
-Inayiloni: Inayiloni iyinto ehlala isikhathi eside, engangeni manzi, futhi engasindi elungele izikhwama zeqhwa eziqandisiwe ezidinga ukunyakaza okuvamile noma ukusetshenziswa ngaphandle.
-I-Polyester: I-polyester ingenye into evamile ehlala njalo evame ukusetshenziselwa igobolondo langaphandle lezikhwama zeqhwa eziqandisiwe, ezinamandla amahle nokumelana nokugqoka.
2. Isendlalelo se-insulation:
-I-Polyurethane Foam: Kuyinto esebenza kahle kakhulu yokuvikela ukushisa, futhi isetshenziswa kakhulu ezikhwameni zeqhwa eziqandisiwe ngenxa yekhono layo elihle kakhulu lokugcina ukushisa.
-Igwebu le-Polystyrene (EPS): eyaziwa nangokuthi i-styrene foam, le nto engasindi ibuye isetshenziswe ngokujwayelekile emikhiqizweni eqandisiwe, ikakhulukazi ezixazululweni zesiqandisi sesikhathi esisodwa.
3. Ulayini lwangaphakathi:
-Icwecwe le-Aluminium noma ifilimu eyenziwe ngensimbi: Lezi zinto ezisetshenziswayo zivame ukusetshenziswa njengama-lining ukuze zisize ukukhombisa amandla okushisa futhi zithuthukise imiphumela yokushisa.
-Ibanga lokudla i-PEVA: Lena impahla yepulasitiki engenabuthi evame ukusetshenziselwa ungqimba lwangaphakathi lwamaphakethe eqhwa, okuqinisekisa ukuthintana okuphephile nokudla.
4. Isigcwalisi:
-Ijeli: I-filler evame ukusetshenziswa yezikhwama zeqhwa eziqandisiwe ijeli, evame ukuqukatha amanzi, ama-polymers (njenge-polyacrylamide) kanye nenani elincane lezithasiselo (njengama-preservatives kanye ne-antifreeze).Lawa majeli angakwazi ukumunca ukushisa okuningi futhi akhulule kancane kancane umphumela wokupholisa ngemva kokubanda.
-Isixazululo samanzi kasawoti: Kwamanye amaphakethe eqhwa alula, amanzi anosawoti angasetshenziswa njengesipholisa ngoba indawo yokuqandisa yamanzi anosawoti iphansi kunaleyo yamanzi ahlanzekile, okuhlinzeka ngomphumela wokupholisa isikhathi eside.
Lapho ukhetha amaphakethe eqhwa aqandisiwe, kubalulekile ukuqinisekisa ukuthi izinto zomkhiqizo ezikhethiwe ziphephile, azihambisani nemvelo, futhi zingahlangabezana nezidingo zakho ezithile, njengokugcina ukudla noma izinjongo zokwelapha.Okwamanje, cabanga usayizi nokuma kwamaphakethe eqhwa ukuze uqinisekise ukuthi afanele isiqukathi sakho noma indawo yokugcina.
