Isikhwama sefriji noma, njengoba kubizwa nangokuthi, isikhwama esisimweni esiyingqayizivele siyinto edingekayo emndenini ohola impilo esebenzayo. Uma uthanda ukuhamba ukuze uphumule emvelweni, izivakashi zihamba emotweni yakho noma ngokuvamile uhambe uhambo olude esitimeleni, khona-ke awukwazi ukukwenza ngaphandle kwesikhwama esiqandisayo esiqandisini! Isikhwama se-thermo sivumela ukuthi kugcinwe umbuso wokushisa okudingekayo ukuze kulondolozwe imikhiqizo efrijini, efriziwe noma efudumele.
Ukukhetha isikhwama sesiqandisisi
Abathengi abangakwazi ukukwazi ukukhetha isikhwama seqandisini, yiziphi izindlela okufanele zizisebenzise uma ukhetha.
Ubukhulu bezinhlamvu
Ama-thermosets amancane aklanyelwe ukuthwala sandwiches ezimbalwa noma izimbiza zeziphuzo, isisindo saso sisuka ku-400 g. Kulesi sikhwama kulula ukuphuza ukudla kwasekuseni ingane noma isidlo somngane womshado. Isilinganiso esikhwameni se-isothermal ikuvumela ukuba uthwale imikhiqizo engu-10 - 15 kg. Izikhwama ezinjalo zigqokwe ezandleni, emahlombe noma ngemuva kwamahlombe. Ukuphatha noma ama-straps amakhulu ayenziwe ngezinto zabo ezithambile.
Izikhwama ezinamandla kakhulu ezikwazi ukugcina kufika ku-30 kuya ku-35 kg zivame ukufakwa kumavili.
Isikhathi sokugcina semikhiqizo esikhwameni
Uma unesithakazelo ekuthengeni okudingekayo kakhulu endlini, ufuna ukwazi ukuthi isikhwama sokupholisa sigcina isikhathi esingakanani sokushisa okulungile?
Isikhathi sokugcina umbuso wokushisa sincike kakhulu ngobukhulu bomkhiqizo. Gcina imikhiqizo ngokushisa okulinganisiwe ngaphandle kwebhethri kungaba amahora angu-3 kuya kwangu-4, ezinkwameni ezincane ezinezikhathi zokugcina ibhethri zanda kumahora angu-7 kuya kwangu-13. Izikhwama ezinkulu zokushisa ziqinisekisiwe ukugcina umbuso wokushisa oyifunayo phakathi nosuku.
Izinto ezivela kuzo izikhwama eziqandisini
I-thermosets yenziwe ngamakhiwe aqinile kakhulu (i-polyester, i-nylon) noma i-polymers eqinile. Njengokufakwa kwe-thermal, izinto zokwaziswa zanamuhla ziyasetshenziswa: i-foam polyethylene noma i-foam polyurethane. Ukusetshenziswa kwalezi zincwadi kunikeza ukunakekelwa okulula nokuhlanzekile komkhiqizo. Kulula ukusula, ugeze ku-daishisher. Ngaphezu kwalokho, uma kwenzeka ukuvuza kwanoma yiluphi uketshezi esikhwameni, umswakama awuthululi. Isikhwama se-thermo sinama-skeleton esenziwe nge-foam enomsoco, evumela ukuthi kungagcini nje ukugcina izinga lokushisa, kodwa futhi hhayi ukuguqula imithwalo kuyo.
Iwaranti ebhodleleni le-thermos
Qinisekisa ukuqaphela lapho uthenga isikhwama ukuthi unesiqinisekiso. Ngokuvamile leli gama liyingcosana - izinyanga ezintathu, kodwa izinhlobo ezithile zebhodlela le-thermos ziqinisekisiwe iminyaka eminingana.
Ukuphila komsebenzi esikhwameni ngokusetshenziswa ngokucophelela kungu-5 - 7 iminyaka.
Isimiso sesikhwama sesiqandisisi
Njengengxenye yokupholisa isikhwama seqandisini, i-ice eyomile nama- accumulator abandayo asetshenziswa . Amabhethri akhiwe ngendlela yezikhwama noma amabhethri epulasitiki, ngaphakathi kwawo isisombululo saline nezithasiselo ezikhethekile ezivumela ukugcina ukubaluleka kokushisa okudingekayo. Ibhethri ibeke okungenani amahora angu-7 efrijini, futhi emva kokuba efakwe esikhwameni se-thermo.
Uma udinga ukugcina ukudla okushisayo esikhwameni sakho, awudingi ukubeka amabhethri abandayo.
Indlela yokusebenzisa isikhwama seqandisini?
Ngaphambi kokugcina imikhiqizo esikhwameni, okokuqala, bafaka amabhethri abilisiwe kuwo. Ngaphambi-sibeka inyama, inhlanzi, imifino kanye nezithelo ezikhwameni ze-cellophane noma iziqukathi zepulasitiki. Ngendlela, ezinye izikhwama ezithengiswa esethi zinetethi ekhethekile yeziqukathi.
Muva nje, izikhwama ze-thermo zisetshenziselwa impilo yansuku zonke kuphela, kodwa futhi nasemisebenzini yobuchwepheshe yezinye izigaba zabasebenzi: izikhwama zisetshenziselwa ukulethwa kokudla okulungiselelwe, abasebenzi bezokwelapha ngokuphatha imithi, izinto zokuhlaziywa, njll.
