Iingcambu ezibangela kunye neeNdlela eziCwangcisiweyo zokuLawula ivumba kwiNkqubo yokuNyanga yeFoyile yeAluminiyam eNgqunyiweyo yokuPakisha ukutya.
Kwintsimi yokupakisha ukutya, Ifoyile yealuminiyam egqunyiweyo iye yaba yinto ephambili yokupakishwa kunye nokugcinwa kweemveliso ezinje ngobisi., itshokholethi, ukutya okuphekiweyo, kunye nokutya okukhawulezayo, enkosi kwiipropati zayo ezikhethekileyo zomqobo, ukumelana nobushushu, kunye nokhuseleko.
Inkqubo yokunyanga linqanaba eliphambili lemveliso yayo. Iququzelela ukuphendulwa kwe-cross-linking ye-coating materials ukwenza ifilimu ekhuselekileyo yokukhusela. Le nkqubo inquma ngokuthe ngqo ukusebenza kokugqibela kwe-foil kunye nokuthotyelwa kwayo kokhuseleko lokutya.
Nangona kunjalo, amavumba acaphukisayo aveliswa ngexesha lokunyanga angonakalisi nje imeko yemveliso kodwa anokuhlala kwiimveliso ezigqityiweyo.. Oku kuphakamisa iinkxalabo zokhuseleko lwabathengi kwaye kubangela imingcipheko yokungathotyelwa kwemigangatho yesizwe efana ne-GB 31604.60-2024.
Ngoko ke, ukuhlalutya ngokucwangcisiweyo oonobangela bevumba kunye nokuseka inkqubo yolawulo esebenzayo egubungela yonke ityathanga lemveliso ibe ngumngeni obalulekileyo ekufuneka ujongwe ukuze kuqhutyelwe uphuhliso lomgangatho ophezulu weshishini..
1. Uhlalutyo lweengcambu ezibangela ivumba kwiNkqubo yokuNyanga
Ukuveliswa kwevumba kutyhutyha yonke inkqubo ukusuka kwizinto eziluhlaza ukuya kwimveliso egqityiweyo. Imithombo yayo engundoqo zizinto ezingaphendulwanga ngokwaneleyo, Iimveliso zemichiza, kunye nezinto ezingcolisayo ezingeniswe ngenxa yolawulo olulambathayo lwenkqubo. Izizathu zingahlelwa ngokwezi ntlobo zintathu zilandelayo:
1.1 Iziphene ngendalo kwiMathiriyeli ekrwada kunye noKuqulunqwa
Iimathiriyeli ekrwada ngowona mthombo wevumba. Ukukhetha okungafanelekanga okanye ukuqulunqwa okuphosakeleyo kukhokelela ngqo kwimiba yokuvumba emva kokunyanga.
- Imiba yeNtsalela yokuSombulula:Ukusetyenziswa kwendawo yokubilisa ephezulu, izinyibilikisi ezinentsalela ephezulu (I-E.G., i-toluene, cyclohexanone) okanye izinyibilikisi zococeko olukumgangatho ophantsi zithetha ukuba ukungcola kwazo kuyasokola ukuguquguquka ngokupheleleyo ngexesha lokunyanga, ekhokelela kwintsalela, ivumba elibi.
- Imingcipheko evela kwiiarhente zokunyanga:Ii-isocyanate monomers zasimahla ezinokubakho kwiiarhente zokunyanga ezisekwe kwi-solvent, kunye neentsalela ezivela kwi-phenolic crosslinkers, inokukhupha amavumba acaphukisayo ngexesha okanye emva kokunyanga kwaye inokubangela umngcipheko wokhuseleko lokufuduka.
- Ungcoliseko lweSubstrate:Ukuba i-oyile yokuqengqeleka engafanelekanga (I-E.G., viscosity ephezulu, uluhlu olubanzi lokubilisa) zisetyenziswa ngexesha le-aluminium foil stock production, i-oyile eshiyekileyo engaguquguqukiyo ngokupheleleyo xa kunyangwa amaqondo obushushu isenokwenza ivumba.
- Ukungalungelelani koqulunqo:Ukongezwa okugqithisileyo kwezongezo ezifana neplastiki okanye izizinzi, okanye ukungahambelani kakuhle phakathi kwamacandelo, kukhokelela kwiimpendulo ezingaphelelanga zokunyanga. Izinto ezingaphendulwanga zinokulikhulula kancinane ivumba ekuhambeni kwexesha.
1.2 Ulawulo olungafanelekanga lweeParamitha zeNkqubo yokuPhila
Ulawulo oluchanekileyo lweeparamitha zenkqubo ngundoqo ekuqinisekiseni ukusabela okupheleleyo; izicwangciso ezingalunganga zibangela ngqo ivumba.
- Ubushushu obungonelanga okanye ixesha:Ukunyanga amaqondo obushushu aphantsi kakhulu okanye ubude bexesha elifutshane kakhulu kukhokelela kwiimpendulo ezingaphelelanga zokudityaniswa kweresin., izinyibilikisi, kunye neearhente zokunyanga. Oku kushiya ngasemva ii-monomers ezingaphendulwanga okanye iimveliso eziphakathi eziba yimithombo yokukhutshwa kwevumba kamva.
- Ukugqithiswa kweNdawo kunye noKuthotywa:Amaqondo obushushu aphezulu kakhulu, ngakumbi kwiinkqubo ezifana ne-electromagnetic induction curing, kunokubangela ukufudumeza kwendawo, okukhokelela ekuthotyweni kwepolymer okanye nakwi-carbonization yokwambathisa. Oku kuvelisa ukutsha okubonakalayo, amavumba e-acrid kunye nezinye iigesi ezicaphukisayo.
- Ukuhamba komoya okungafanelekanga kunye nokuPhucula umoya:Isantya sokuhamba komoya esingonelanga ngaphakathi kwi-oveni yokunyanga asikwazanga ukususa ngokukhawuleza iimveliso eziguquguqukayo kunye nezinyibilikisi ezishiyekileyo ezenziwe ngexesha lokuphendula., ukuzivumela ukuba ziqokelele kwaye zibenakho ukungcolisa kwakhona imveliso. Ukuhamba komoya okuphezulu ngokugqithisileyo, Nangona kunjalo, inokuchaphazela umgangatho womphezulu wokwaleka.
1.3 Ungcoliseko lwesibini oluvela kwiNdawo yeMveliso kunye neZixhobo
Ukucoceka kwendawo yemveliso kunye nezixhobo zichaphazela ngokuthe ngqo ukucoceka kwemveliso.
- Ungcoliseko loMoya okwiNdawo:Ukuba ungcoliseko olufana nezinye izinyibilikisi eziguquguqukayo zezinto eziphilayo okanye uthuli zikhona emoyeni wocweyo, zinokubhengezwa ngumphezulu wokwambathisa onganyangekanga kwaye emva koko zibe “ebanjisiwe” ngaphakathi kwefilimu ephilisiwe, ukudala amavumba anzima.
- Usulelo lwezixhobo:Izixhobo ezifana nee-oveni zokunyanga kunye neebhanti zokuhambisa ziqokelela iimveliso zokubola., iintsalela zepolymer, kunye negrisi kwimigangatho engaphakathi ekusebenzeni ixesha elide. Ngaphantsi kobushushu obuphezulu obuqhubekayo, ezi iidiphozithi zinokuzibolisa ngokwazo okanye zinxibelelane neemveliso ezintsha, ukuvelisa amavumba atshileyo kunye namanye amavumba abambelela kumphezulu wefoyile.
- Impembelelo yeeNkqubo zoMsinga:Ngexesha lokuqhawula kunye nokuphumla, ukuba kusetyenziswe uxinzelelo olugqithisileyo, kubangela ukuba ikhoyili ibe buhlungu kakhulu, inokuthintela ukusasazwa kunye nokubaleka kwezinto eziguquguqukayo ezivaleleke phakathi kweeleya ngexesha lokugcinwa kunye nokuthutha. Oku kunokubangela ivumba elibonakalayo xa umsebenzisi wokugqibela evula ipakethe.
