Ngaba umatshini wokupakisha ikofu uqinisekisa njani ukuba uTsha kunye nokuGcinwa kwevumba?

Intshayelelo:

Xa kuziwa kwihlabathi lekofu, ukutsha kunye nevumba zizinto ezimbini ezibalulekileyo ezinokwenza okanye zophule ikomityi yejoe. Inkqubo entsonkothileyo yokupakishwa kwekofu idlala indima ebalulekileyo ekuqinisekiseni ukuba ezi mpawu ziyagcinwa ukusukela oko iimbotyi zigcadwa ukuya kuthi ga kwikomityi yakho. Oomatshini bokupakisha ikofu bayitshintshile le nkqubo, bevumela abavelisi ukuba bagcine inqanaba elifunwayo lokutsha kunye nevumba ngelixa besandisa ixesha leshelufu yekofu. Kweli nqaku, siza kuphonononga indlela aba matshini basebenza ngayo kunye nobuchule obahlukeneyo ababusebenzisayo ukuqinisekisa ukuba ikofu yakho ihlala imnandi kwimizwa yakho.

Ukubaluleka kokuTsha kunye nevumba:

Ngaphambi kokuba ujonge kubugocigoci boomatshini bokupakisha ikofu, kubalulekile ukuqonda ukuba kutheni ukutsha kunye nokugcinwa kwevumba kubaluleke kakhulu kwishishini lekofu. Ukutsha kubhekisa kwixesha apho iimbotyi zekofu zigcina incasa kunye namavumba azo awohlukileyo. Kuyaziwa ngokubanzi ukuba ikofu ikwincasa yayo ephezulu kwiiveki nje zosiwe, emva koko iphulukana nokungcangcazela kunye nokutsha kwayo. Kwelinye icala, ivumba elimnandi livumba elimnandi nelinomtsalane elongeza kumava okungcamla ikomityi yekofu.

Indima yoomatshini bokuPakisha ikofu:

Oomatshini bokupakisha ikofu, abakwabizwa ngokuba zizixhobo zokupakisha ikofu, benzelwe ukutywina iimbotyi zekofu okanye ikofu egayiweyo kwizinto zokupakisha ezingangeni moya, ezinje ngeengxowa okanye iinkonkxa. Eyona njongo iphambili kukwenza umqobo okhusela okungaphakathi kwizinto ezingaphandle ezinokuwuthoba umgangatho wekofu, kuquka ukuchanabeka kwioksijini, ukufuma, ukukhanya, kwanokuguquguquka kobushushu. Aba matshini baphatha yonke inkqubo yokupakisha, ukusuka ekugcwaliseni izinto zokupakisha ngekofu ukuya ekuyivaleni, ukuqinisekisa ukuba imveliso ihlala intle kwaye inevumba elimnandi de ifike kumthengi.

Iindlela zokutywina:

Ukufeza umsebenzi wokugcina ubutsha kunye nevumba elimnandi, oomatshini bokupakisha ikofu basebenzisa iindlela ezahlukeneyo zokutywina. Makhe sihlolisise ezinye zezona zixhaphakileyo:

Ukutywinwa kweVacuum:

Ukutywinwa kwevacuum yindlela esetyenziswa kakhulu kwipakethe yekofu. Le ndlela ibandakanya ukususa umoya kwizinto zokupakisha ngaphambi kokuba ivalwe, ukudala indawo yokucoca ngaphakathi. Ngokuphelisa ioksijini, ukutywinwa kwevacuum kunciphisa kakhulu amathuba oksijini, okunokuthi kube nefuthe elibi kwincasa yekofu kunye nevumba elibi. Obu buchule bukwanceda ekuthinteleni ukukhula komngundo, iintsholongwane, okanye ezinye izinto ezingcolisayo ezikhula kakuhle xa kukho ioksijini.

Ukutywinwa kwevacuum ngokuqhelekileyo kuphunyezwa ngenkqubo enamanyathelo amabini. Okokuqala, ikhofi ifakwe kwizinto zokupakisha, kwaye njengoko isikhwama sitywinwe, umoya ogqithiseleyo uyasuswa. Nje ukuba inqanaba levacuum elifunwayo lifikelelwe, ipakethe ivalwe ngokuqinileyo, iqinisekisa ukuba ikofu ihlala intsha ixesha elide.

Ukupakishwa kweAtmosphere eLungisiweyo (MAP):

I-Modified Atmosphere Packaging (MAP) yenye indlela yokutywina edumileyo esetyenziswa ngoomatshini bokupakisha ikofu. Esikhundleni sokudala i-vacuum, i-MAP ibandakanya ukutshintshwa kwe-atmospheric ngaphakathi kwepakethe kunye nomxube othile wegesi, ngokuphindaphindiweyo ukudibanisa i-nitrogen, i-carbon dioxide, kwaye ngamanye amaxesha ixabiso elincinci le-oxygen. Ukuqulunqwa komxube wegesi kunokwenziwa ngokwezifiso ukuze kuhambelane neemfuno ezithile zekofu epakishwayo.

Ubuchwephesha busebenza ngokulawula ukubunjwa kwegesi ngaphakathi kwepakethe ukwandisa ubomi beshelufu yekofu. I-nitrogen, igesi engasebenziyo, idla ngokusetyenziselwa ukususa ioksijini, ngaloo ndlela inqanda i-oxidation. Kwelinye icala, ikharbon diokside inceda ekulondolozeni ivumba elimnandi ngokunqanda ukonakala kwezinto ezinevumba elibi. Ngokulawula iatmosfera, i-MAP idala indawo ekhuselayo ekhusela ikofu ekuwohlokeni ngelixa igcina ukutsha kunye nevumba layo ixesha elide.

Ukugcinwa kwevumba:

Ukugcina ivumba lekofu kubaluleke kakhulu njengokugcina ubutsha bayo. Oomatshini bokupakisha ikofu baye bavela ukuze babandakanye iindlela ezininzi zokuqinisekisa ukuba ivumba elimnandi lekofu lihlala linjalo kubomi bayo beshelufa. Makhe sihlolisise ezinye zezi ndlela:

Indlela enye yeValve yokukhupha amanzi:

Iivalve zendlela enye yokukhupha amanzi ziyinto edumileyo kwipakethe yekofu. Ezi zivalo zincinci ziqhele ukudityaniswa kwiingxowa zekofu ukukhulula i-carbon dioxide engaphezulu ekhutshwa ngokwemvelo yikofu esanda kugcadwa. Ikharbon diokside, ephuma kwinkqubo yokuqhotyiswa, iyaqhubeka ikhutshwa ziimbotyi zekofu nasemva kokuba zicoliwe okanye ziphelele. Ukuba le gesi ayikhululwa, inokukhokelela ekwakhiweni koxinzelelo ngaphakathi kwipakethe, echaphazela umgangatho wonke wekhofi.

Ivalve yendlela enye yokukhupha umoya ivumela icarbon dioxide ukuba ibaleke ngelixa ikhusela ioksijini ukuba ingangeni kwipakethe. Le valve yenzelwe inwebu evumela kuphela igesi ukuba idlule kwicala elinye, iqinisekisa ukuba ikofu ihlala ikhuselekile ngaphandle kokuphazamisa ukutsha kunye nevumba layo. Ngokugcina ulungelelwaniso olufanelekileyo lwerhasi, ivalve ikhusela ngempumelelo incasa yekofu namavumba, ibonelela ngamava akhethekileyo oluvo kumthengi.

Ukupakishwa kweFoil etywiniweyo:

Obunye ubuchule obusetyenziselwa ukugcinwa kwevumba kukupakishwa kwefoyile etywiniweyo. Le ndlela ibandakanya ukubeka ikofu kwizinto zokupakisha eziqukethe iileya ezininzi, ngokuqhelekileyo kuquka i-aluminium foil layer. Le foil isebenza njengomqobo kwioksijini, ukukhanya, nokufuma, nto leyo enokuba nemiphumo eyingozi kwivumba lekofu.

Indlela yokupakisha i-foil etywiniweyo iqinisekisa ukuba iikhompawundi ezinevumba elimnandi ezikhoyo kwikofu zikhuselwe kwizinto zangaphandle. Ngokudala itywina eliqinileyo, ukupakishwa kuthintela ukulahleka kwamavumba aguqukayo kwaye kugcine ivumba elimnandi lekofu de ivulwe ngumthengi.

Isishwankathelo:

Ukuqukumbela, oomatshini bokupakisha ikofu badlala indima ebalulekileyo ekuqinisekiseni ukutsha kunye nokugcinwa kwevumba lekofu kubo bonke ubomi bayo beshelufu. Ngokusebenzisa ubuchule obunje ngokutywinwa kwevacuum kunye nokupakishwa kweatmosfera elungisiweyo, aba matshini benza indawo ekhuselayo ekhusela ikofu kwioksijini, ukufuma kunye nokukhanya. Ukongeza, iimpawu ezinjengeevalve zokususa igassing yendlela enye kunye nokupakishwa kwefoyile etywiniweyo ngakumbi zinegalelo ekugcinweni kwevumba, evumela ikofu ukuba igcine ivumba layo elihendayo de ibe yenziwe. Ngoncedo lwaba matshini baphucukileyo kunye nobuchule bokutywina, abathandi bekofu banokuzonwabisa ngekomityi yejoe enencasa eninzi, ivumba elimnandi, kunye nolwaneliseko olupheleleyo lweemvakalelo. Ke kwixesha elizayo xa usonga umxube owuthandayo, khumbula inkqubo entsonkothileyo kunye nokuzinikela okungena ekulondolozeni eyona njongo yekofu yakho.
