Inkqubo yokuvelisa i-PE kraft CB

I-PE Kraft CB, emele i-Polyethylene Kraft Coated Board, luhlobo lwempahla yokupakisha ene-polyethylene yokugqoka kwelinye okanye kumacala omabini ebhodi ye-Kraft. Olu tyaba lubonelela ngesithintelo esihle sokufuma, sisenza ukuba ibe yinto efanelekileyo yokupakisha iimveliso ezahlukeneyo, ngakumbi ezo zinobuntununtunu.

Inkqubo yokwenziwa kwe-PE Kraft CB ibandakanya amanyathelo amaninzi, kuquka:

1. Ukulungiswa kweBhodi yeKraft: Isinyathelo sokuqala sibandakanya ukulungiselela ibhodi yeKraft, eyenziwe kwi-pulp yomthi. I-pulp ixutywe neekhemikhali, ezifana ne-sodium hydroxide kunye ne-sodium sulfide, kwaye emva koko iphekwe kwi-digester ukususa i-lignin kunye nezinye izinto ezingcolileyo. I-pulp evelayo iye ihlanjwe, ifakwe i-bleach, kwaye iphuculwe ukuvelisa ibhodi ye-Kraft eyomeleleyo, egudileyo, kunye neyunifomu.

2. Ukugquma ngePolyethylene: Emva kokuba ibhodi yeKraft ilungisiwe, ifakwe nge-polyethylene. Oku kuqhele ukwenziwa kusetyenziswa inkqubo ebizwa ngokuba yi-extrusion coating. Kule nkqubo, i-polyethylene etyhidiweyo ikhutshelwa phezu kwebhodi ye-Kraft, ethi ipholiswe ukuqinisa i-coating.

3. Ukuprintwa kunye nokuQeda: Emva kokugquma, i-PE Kraft CB inokuprintwa nayo nayiphi na imizobo efunwayo okanye umbhalo usebenzisa iindlela ezahlukeneyo zokushicilela. Imveliso egqityiweyo inokusikwa, igoqwe, kwaye ifakwe i-laminated ukudala izisombululo zokupakisha eziqhelekileyo ezihlangabezana neemfuno ezithile zabathengi.

4. Ukulawulwa koMgangatho: Kuyo yonke inkqubo yokuvelisa, amanyathelo okulawula umgangatho ongqongqo aqeshwe ukuqinisekisa ukuba i-PE Kraft CB ihlangabezana nayo yonke imigangatho efanelekileyo kunye neenkcukacha. Oku kubandakanya ukuvavanywa kokumelana nokufuma, ukubambelela, kunye nezinye iimpawu eziphambili zokusebenza.

Ngokubanzi, inkqubo yokuvelisa i-PE Kraft CB ilawulwa kakhulu kwaye ichanekile, ibangele izinto zokupakisha ezihlala zihlala kwaye zithembekile. Ngeempawu zayo eziphezulu zokuthintela ukufuma, lukhetho olufanelekileyo lokupakisha uluhlu olubanzi lweemveliso, ukusuka kukutya kunye neziselo ukuya kwi-elektroniki kunye namayeza.
