Yintoni inkqubo yokuvelisa imibhobho yeplastiki?

Iinkqubo yokuvelisa imibhobho yeplastikingokuqhelekileyo kubandakanya amanyathelo amaninzi, anokwahluka ngokuxhomekeke kuhlobo lweplastiki esetyenziswayo kunye neemfuno ezithile zemveliso yokugqibela. Nangona kunjalo, nantsi inkcazo ngokubanzi yenkqubo yokuvelisa imibhobho yeplastiki:

ULungiselelo lweMathiriyeli ekrwada: Inkqubo iqala ngokukhethwa kunye nokulungiswa kwemathiriyeli ekrwada. Iiplastiki zeplastiki, ezifana ne-polyethylene (PE), i-polyvinyl chloride (PVC), okanye i-polypropylene (PP), zizinto eziqhelekileyo ezisetyenziselwa ukwenza iipayipi zeplastiki. Ezi mathiriyeli ekrwada zibonelelwa ngohlobo lweepellet okanye umgubo.

Ukunyibilika kunye nokuxuba: I-resin yeplastiki iyancibilika kwi-extruder, engumatshini osebenzisa ukushisa kunye noxinzelelo kwizinto eziluhlaza, ukuyijika ibe yifom etyhidiweyo. Ngeli nqanaba, izongezo ezinje ngemibala, izinzisi, kunye neearhente zokuqinisa zinokuxutywa neplastiki etyhidiweyo ukukhulisa iipropathi zemveliso yokugqibela.

Extrusion: Iplastiki etyhidiweyo inyanzeliswa kwidayisi, enika umbhobho ubume obunqwenelekayo kunye nobukhulu. Le nkqubo yaziwa ngokuba yi-extrusion. Umbhobho okhutshiweyo unokudlula kwinkqubo yokulinganisa ukuqinisekisa ukuba imilinganiselo yayo ichanekile kwaye ifana.

Ukupholisa kunye nobukhulu: Wakuba umbhobho ukhutshiwe, upholiswa kusetyenziswa amanzi okanye umoya ukuqinisa iplastiki. Ukupholisa kubalulekile ukukhusela i-deformation kunye nokugcina uzinzo lwe-dimensional yombhobho. Emva kokupholisa, umbhobho unokungena kwisilinganisi, apho ugqithwa kwimikhono yokulinganisa okanye iitanki zevacuum ukufikelela kububanzi obufunwayo kunye nobukhulu bodonga.

Ukusika kunye nokupakisha: Emva kokulinganisa, umbhobho unqunywe ubude obuthile usebenzisa oomatshini bokusika. Imibhobho esikiweyo emva koko ipakishwe okanye ibotshwe ukuze ipakishwe kwaye ithuthwe.

Ukulawulwa komgangatho: Kuyo yonke inkqubo yokuvelisa, amanyathelo okulawula umgangatho aphunyezwa ukuqinisekisa ukuba imibhobho ihlangabezana nemigangatho efunekayo kunye neenkcukacha. Oku kunokubandakanya ukuvavanya iimpawu ezibonakalayo kunye nomatshini wemibhobho, kunye nokuhlola iziphene okanye ukungafezeki.

Ukupakishwa nokuThunyelwa: Ekugqibeleni, imibhobho egqityiweyo ipakishwa ngokweemfuno zabathengi ize ithunyelwe kwindawo eya kuyo ukuze isetyenziswe kwizinto ezahlukahlukeneyo, ezinjengokusasazwa kwamanzi, ukuhambisa amanzi, ukunkcenkceshela okanye ukuthutha igesi.

Ngokubanzi, ukuveliswa kwemibhobho yeplastiki kubandakanya indibaniselwano yokunyibilika, ukubunjwa, ukupholisa, kunye neenkqubo zokulawula umgangatho wokuvelisa imibhobho ekumgangatho ophezulu ofanelekileyo kuluhlu olubanzi lwezicelo.
