Ukupakishwa okuZinzileyo Indima yeResin ye-EVOH
Uzinzo luye lwavela njengomxholo obalulekileyo kumashishini amaninzi, kwaye icandelo lokupakisha alikho ngaphandle. Ngenxa yokukhathazeka okwandayo malunga nenkunkuma yeplastiki kunye nempembelelo yokusingqongileyo, iinkampani ziya zifuna ezinye iindlela ezizinzileyo. I-EVOH (i-ethylene vinyl alcohol) I-resin ifumene ingqalelo njengesisombululo esisebenziseka lula nesisebenzayo esihlangabezana nezi mfuno.
Ukupakisha okuzinzileyo akubandakanyi nje kuphela ukukhethwa kwezinto kodwa nendlela ezisetyenziswa ngayo kulo lonke ixesha lomjikelo wobomi bemveliso. I-Evoh Resin inomtsalane kakhulu ngenxa yeempawu zayo ezibalaseleyo zokuthintela. Ezi mpawu zibalulekile ekugcineni imveliso itsha ngelixa zandisa ixesha lokuphelelwa kwayo, nto leyo enciphisa ngempumelelo inkunkuma. Xa abathengi bekhetha iimveliso ezihlala ixesha elide, oko kukhokelela ekunciphiseni ubuninzi bokuthengwa kunye nenkunkuma yokupakisha elandelayo.
Ishishini lokutya libe yingenelo enkulu kwiimpawu ze-EVOH resin. Iimpawu zokutya eziphambili ngoku ziyayisebenzisa ekupakisheni kwazo inyama, itshizi, kunye nokutya okulungele ukutyiwa. Inzuzo eyongezelelweyo kukuba i-EVOH inokufakwa kwizakhiwo ezinokuphinda zisetyenziswe, okwenza kube lula ukuhambelana nemigaqo yezoqoqosho olujikelezayo. Njengoko iinkampani zijonge ukunciphisa umngcipheko wazo wekhabhoni, ukudibanisa i-EVOH ekupakisheni kunciphisa impembelelo yokusingqongileyo ngelixa kugcinwa ukuthembeka kwemveliso.
Ngaphezu koko, uxinzelelo lomthetho longeza ungqimba lomfutho ekusebenziseni I-Evoh KwiphakhejiOorhulumente kunye nemibutho eyahlukeneyo baphumeza imithetho engqongqo malunga nenkunkuma yeplastiki, nto leyo enyanzela abavelisi ukuba basebenzise iindlela ezinobuhlobo nokusingqongileyo. Indlela ye-EVOH yokunyibilika emanzini nenokuphinde isetyenziswe iyibeka njengokhetho olufanelekileyo lokuhlangabezana neemfuno zabathengi kunye nemigangatho yolawulo.
Amashishini ezithambiso kunye namayeza ayayiqonda inzuzo yokufaka i-EVOH kwizicwangciso zawo zokupakisha. Njengoko iimveliso zinobuthathaka kumswakama kunye neoksijini, ukusebenzisa i-EVOH kunceda ukugcina ukusebenza kwazo kwaye kwandisa ukusetyenziswa kwazo. Njengoko imithetho itshintsha, ukuqinisekisa ukhuseleko lwemveliso kunye nokuthobela kuya kugcina abavelisi bexhomekeke kwizixhobo ezifana ne-EVOH ezithembisa ukuqina nokusebenza.
Nangona kukho iingenelo ezininzi, imakethi ye-resin ye-EVOH ijongene nemingeni enxulumene kakhulu neziphumo zeendleko. Nangona iimpawu zayo ziyenza ibe lukhetho olunomtsalane lokupakisha oluzinzileyo, utyalo-mali lokuqala lunokuba phezulu. Nangona kunjalo, njengoko iinkqubo zemveliso ziphucuka kwaye ukusebenza kakuhle kufezekiswa, ezo ndleko kulindeleke ukuba zehle, nto leyo eyenza i-EVOH ifikeleleke ngakumbi kubavelisi abaninzi.
Isishwankathelo, I-resin ye-EVOH ikhawuleza ivele njengesiseko sentshukumo yokupakisha ezinzileyo. Amandla ayo okunciphisa inkunkuma ngelixa iqinisekisa ukuba imveliso ihlala ixesha elide ayenza ibe yimpahla engumzekelo kumashishini ahlukeneyo. Njengoko imfuneko yeendlela ezinobuhlobo nokusingqongileyo iqhubeka isanda, i-EVOH kusenokwenzeka ukuba idlale indima ebaluleke ngakumbi ekubumbeni ikamva lokupakisha.
