Ukupakishwa kokutya okusemgangathweni umxholo wococeko awufezekanga

Izinto zokupakisha ukutya kwezempilo azinamgangatho omanyeneyo okwangoku zasekhaya aziyi kuqulunqa ezidityanisiweyo, ukusebenza okusemgangathweni kwezinto zokupakisha ukutya kwezempilo, kwaye kuphela kwinani elincinci leemveliso kwimithetho eqhelekileyo, njengokupakishwa okuguquguqukayo kwe-GB/T10004 & ndash;
Ngo-2008 ukupakisha ifilimu edibeneyo yeplastiki, isikhwama, i-compound extrusion eyomileyo, 'izibonakaliso zentsalela ye-solvent kwizibonelelo ezihambelanayo.

Uninzi lwemigangatho yococeko lwemathiriyeli yokupakishwa kokutya ayisebenzi okwangoku iintlobo ezininzi zokupakishwa kokutya.
Ukufumana intsalela ye-solvent, amazwe ahlukeneyo kwiithagethi zezibonelelo zayo.
Kwi GB/T10004 & ndash;
Ngo-2008 ukupakisha ifilimu ehlanganisiweyo yeplastiki, ibhegi, i-compound eyomileyo ye-compound extrusion, 'izibonelelo eziphambili kwixabiso lentsalela ye-solvent ayikho ngaphezu kwe-5 mg / m2, kodwa ayizange ichaze ukuba luhlobo luni lwe-solvent, kuluhlu lwe-5 mg / m2 yonke. iintlobo zesinyibilikisi sobuninzi azenzi ulwahlulo oluneenkcukacha ezingaphezulu.
Umgangatho wezempilo wesizwe ukwanqanda ukusebenzisa inkunkuma yeplastiki njengemveliso yempahla ekrwada yezikhongozeli zokutya zeplastiki.
Kodwa kukho ukufihlwa okukhulu komonakalo, owenziwe kwimizi-mveliso ekrwada kwizikhongozeli zokutya zeplastiki.
Kumda wesalathiso somgangatho wesikhongozelo seplastiki ukhululekile kakhulu, ikomiti esemgangathweni yesizwe ngoku isebenzela ukuhlaziya nokuphucula umsebenzi osemgangathweni.

Uninzi lwemigangatho yemveliso yezinto zokupakisha ayisiyonxalenye kuphela kwimfuno yeentsalela ze-solvent ubhaqo inkcazo esemgangathweni yezalathisi ezilula zoluvo, njengokupakisha imathiriyeli akufuneki ibe nevumba elikhethekileyo, ukupakisha ulwelo olufunxayo akunakuba nevumba elikhethekileyo, njl. njl. akukho mfuneko zezalathi zobungakanani obuthile ezibekiweyo.
Ukupakishwa kokutya kwinkqubo yokuveliswa nokungenakuthinteleka kukho izinyibilikisi ezishiyekileyo.
Kwi-gravure yoshicilelo lweplastiki yezinto ezidibeneyo kunye nenkqubo ye-solvent eyomileyo, kufuneka kusetyenziswe i-solvent eninzi yezinto eziphilayo ezifana ne-toluene, i-ethyl acetate kunye ne-ethyl ketone, njl. Yiba ngumphunga, kodwa ngenxa yezizathu ezahlukeneyo kwimveliso eyiyo kuyakuhlala kukho ngaphezulu okanye ngaphantsi asisinyibilikisi esiguquguqukayo ngokupheleleyo, eyaziwa ngokuba zizinyibilikisi ezishiyekileyo.
Izinyibilikisi eziyintsalela yindibaniselwano yeentlobo ezininzi zesinyibilikisi, ngokuqhelekileyo xa umxholo wezinyibilikisi ezishiyekileyo ngaphantsi kwexabiso elithile lomqobo, imvakalelo yokujoja ayinakubuva ubukho bayo, kodwa intsalela yenyibiliki ephezulu iyabonwa ngabantu.
NjengePVC (
PVC)
Ukusonga kweplastiki kumhlaza kubangele iziphumo ezinamandla ekhaya.
I-GB9681—
1988 ukutya ukupakishwa PVC ukubumba umgangatho wezempilo imveliso 'kwilungiselelo ethile, umxholo vinyl chloride monomer ngaphantsi okanye ilingana 1 mg ngekhilogram.
Ukwakheka kwe-vinyl chloride monomer kuqulethwe kwifilimu yokutya ye-PVC, emva kokuba negalelo kumzimba womntu ube ne-carcinogenicity.
I-European Union kunye ne-United States, eJapan, ziye zavala le mveliso esetyenziselwa ukutya.
Ihlaziywe amatyeli aliqela, kodwa ubukhulu becala ukwenza ezinye zezi parameters zitshintshe.
“
Iziganeko zefilimu yokubambelela & kuyo yonke;
Kwaphinda kwabhentsisa imigangatho efanelekileyo yelizwe lethu ikhuphe ukuqhwalela komsebenzi.
Ngoko ke imathiriyeli yokupakishwa kokutya ekubhaqweni kweentsalela zenyibilikisi ukuphuhlisa isalathiso sobungakanani kuyafuneka.
