Umenzi ochwephesha woomatshini be-thermoforming.
Ukwakheka kwePVC: I-PVC yipolymer ye-thermoplastic equka i-vinyl chloride monomers. Ubume bayo beekhemikhali bunika ukomelela, ukuguquguquka, kunye nokuqina.
Iimpawu zesithintelo sePVC ngokuchasene neoksijini, umphunga wamanzi, kunye nezinye iigesi zenza kube lolona khetho lubalaseleyo lokugcina ukutsha kokutya kunye nokwandisa ubomi beshelufu. Ukuguquguquka kwayo kunye namandla aqinisekisa ukuba ukupakishwa kunokumelana nobunzima bezothutho kunye nokuphatha ngaphandle kokuphazamisa imveliso eyikhuselayo. Ngaphezu koko, ukucaca kwePVC kuvumela ukubonakala kwemveliso egqwesileyo, into ebalulekileyo yokwaneliseka kwabathengi kunye neenjongo zentengiso. Ukunganyangeki kweekhemikhali kuyangena kwakhona, ukuthintela ukungcoliseka kunye nokugcina ubunyulu bomxholo wokutya.
Amaphepha ePVC asetyenziselwa ukwenza iintlobo ngeentlobo zezisombululo zokupakisha ukutya. Ezi ziquka iipakethe zamadyungudyungu zonikezelo lokutya komntu ngamnye, izikhongozeli zeclamshell ezihlala zisetyenziselwa iziqhamo, imifuno, kunye nezinto zokubhaka, kunye neetreyi zenyama, inkukhu, kunye nokutya kwaselwandle. Ukuguquguquka kwePVC kuyivumela ukuba ibunjwe kwipakethe ekhuselekileyo yayo nayiphi na imveliso yokutya, exhasa iimfuno ezahlukeneyo zemarike.
a.Umatshini wokwenza uxinzelelo olubi
I-Negative Pressure Forming, eyaziwa ngokuba yi-vacuum forming, yinkqubo eyenziwe lula ye-thermoforming apho i-sheet ye-PVC efudumeleyo igqunywe phezu kokungunda kwaye iphantsi koxinzelelo lwe-vacuum. Obu buchwephesha bufaneleke ngakumbi ekudaleni iipakethe ezineenkcukacha zoyilo ngeendleko eziphantsi, nto leyo ibalulekileyo kushishino lokutya olukhuphisana kakhulu. Ukusetyenziswa koxinzelelo olubi kuqinisekisa ukuba iphepha le-PVC lihambelana ngokuchanekileyo kwi-mold, okubangela ukuba ubukhulu obufanayo kunye nomgangatho ohambelanayo kwiimveliso ezigqityiweyo.
b. Umatshini wokubumba iPlastiki
Ngokufana nokusebenza kuMshini wokuFaka uxinzelelo olubi, iPlastiki yokuFaka iVacuum ithatha eli nyathelo ngokunika ulawulo oluchanekileyo ngakumbi kwinkqubo yokubumba. Oku kuchaneka kubalulekile xa kusenziwa ukupakishwa kweemveliso zokutya ezinovakalelo, apho nokuphambuka okuncinci kunokukhokelela ekonakaleni okanye ekosulelweni kwemveliso. Ubuchule bomatshini bokuphatha umthamo ophezulu wemveliso buwenza ulungele ukuhlangabezana nemfuno enkulu eqhelekileyo kwishishini lokupakisha ukutya.
a. Iinkcazelo Ngeempawu Zomqobo: I-PVC ibonelela ngeepropathi ezigqwesileyo zesithintelo ngokuchasene neoksijini, ukufuma, kunye nezinye iigesi, ezinceda ekugcineni ukutsha kunye nokwandisa ubomi beshelufu yeemveliso zokutya. Oku kubaluleke ngakumbi kwizinto ezinokonakala njengenyama, ubisi, kunye nokutya osele kusele kutyiwe.
b. Amandla oomatshini: Amandla kunye nokuqina kwePVC kwenza ukuba ixhathise impembelelo kunye nokukrazula, ukubonelela ngokhuseleko oluthembekileyo lweemveliso zokutya ngexesha lokuthutha kunye nokuphatha. Oku kunciphisa umngcipheko wokwaphulwa kokupakishwa okunokukhokelela ekonakaleni okanye ekosulelweni kokutya.
c. Iindleko-Ngempumelelo: I-PVC ayibizi kakhulu ukuvelisa xa kuthelekiswa nezinye iipholima ezininzi ezisetyenziswa ekupakisheni ukutya. Oku kusebenza kakuhle kweendleko kuyenza ibe yindlela enomtsalane kubavelisi abajonge ukunciphisa iindleko ngelixa begcina imigangatho yokupakishwa ephezulu.
d. Ukuguquguquka: Ukuguquguquka kwePVC kukuvumela ukuba wenziwe ngeendlela ezahlukeneyo kunye nobukhulu, ukuhlalisa uluhlu olubanzi lweemveliso zokutya. Ukusuka kwiifilimu ezibhityileyo ukuya kwizikhongozeli eziqinileyo, iPVC inokubumba ngokulula ukuhlangabezana neemfuno zokupakisha ezithile.
e. Ukungafihli: Ukucaca kwePVC kuqinisekisa ukuba iimveliso zibonakala kubathengi ngaphandle kokuvula ukupakishwa, ukuphucula isibheno semveliso kunye nokuququzelela isigqibo sokuthenga. Oku kungafihlwa kubalulekile kubathengi kunye nokwaneliseka.
f. Ukumelana neMichiza: I-PVC iyaxhathisa i-oyile, amafutha, kunye neekhemikhali ezininzi, iyenza ilungele ukupakishwa kweentlobo ngeentlobo zeemveliso zokutya ngaphandle komngcipheko wokudityaniswa kweekhemikhali ezinokubeka esichengeni ukhuseleko lokutya.
Ngelixa iPVC ibonelela ngezinto ezininzi eziluncedo, ifuthe layo lokusingqongileyo ngumbandela wengxoxo eqhubekayo. Iinkxalabo malunga nokuzinza kokusebenzisa i-PVC ekupakisheni kokutya kugxininise kumjikelezo wobomi bayo-ukusuka kwimveliso ukuya ekulahlekeni. Inkqubela phambili yangoku kubuchwephesha bokurisayikilisha sele iqalile ukuthomalalisa ezi nkxalabo ngokuphucula ukusebenziseka kwakhona kwePVC. Ngaphaya koko, ishishini litshintshela kwizongezo ezilungele ngakumbi i-eco-friendly ukomeleza izinga lokubola kwePVC emva kokusetyenziswa.
Kumhlaba oguquguqukayo wokupakishwa kokutya, iimathiriyeli zephepha lePVC zigqama njengesisombululo esiguquguqukayo nesisebenzayo, sinika intaphane yeenzuzo kubenzi, abathengisi, kunye nabathengi ngokufanayo. Ngokuqonda iipropathi zabo, usetyenziso, kunye noomatshini bokulungisa, abachaphazelekayo banokusebenzisa i-PVC ukuphucula umgangatho wemveliso, ukwandisa ukusebenza kakuhle kwemveliso, kunye nokuhlangabezana nemigangatho yolawulo. Nangona kunjalo, imingeni yozinzo ehambelana ne-PVC igxininisa ukubaluleka kokuqhubeka kwezinto ezintsha kunye nentsebenziswano ukuqinisekisa ukulingana phakathi kokusebenza kunye noxanduva lokusingqongileyo kwimisebenzi yokupakisha ukutya.
