Kwiminyaka emibini edlulileyo, ukuveliswa kweemibhobho zensimbi ezifakwe kwiplastiki kwilizwe lam kuye kwaphuhliswa ngokukhawuleza, ngakumbi kwintsimi yokubonelela ngamanzi.Okwangoku, ngaphezu kwe-90% yemibhobho yokubonelela ngamanzi kwizakhiwo eziphakamileyo e-Shanghai isebenzisa imibhobho yentsimbi eneplastiki.
Umbhobho wensimbi owenziwe ngeplastiki awunawo amandla aphezulu, ukuqina, ukuxhathisa umlilo, kunye nokumelana nobushushu bemibhobho yensimbi kodwa unococeko kunye nokukhuselwa kokusingqongileyo kunye nokusebenza okungenakulinganiswa kwemibhobho yeplastiki.Imibhobho ehlanganisiweyo.
Umbhobho wensimbi owenziwe ngeplastiki ukhutshelwe umbhobho weplastiki kwaye uwugqume ngenqwanqwa elincamathelayo, emva koko ufakwe kumbhobho wentsimbi, uwufudumeze, ucinezele, upholile, umilise kunye nombhobho wentsimbi, kwaye udibanise umbhobho weplastiki kunye nombhobho wentsimbi. ngokuqinileyo kunye, engasetyenziselwa ukuthuthwa kwamanzi abandayo okanye ukuhanjiswa kwamanzi ashushu.
I-1.Izixhobo zeplastiki ze-Lining kunye nokuhamba kwenkqubo
(1) Isixhobo sokubumba umbhobho wePlastiki
Imibhobho yeplastiki iveliswa nge-screw extruders, kubandakanywa i-extruders eshushu, iitrektara ze-crawler, ukupholisa i-vacuum, iitanki zokubumba, oomatshini bokusika, umbane kunye neenkqubo zokulawula ubushushu, njl.
(2) Izixhobo zeplasitiki ezifakwayo
①Itafile yokutya isetyenziselwa ukubeka imibhobho yentsimbi kunye nokufaka imibhobho yeplastiki kwimibhobho yentsimbi;
②Inkqubo yokuhanjiswa kwekhonkco iqhuba umbhobho wentsimbi kwisikhululo ngasinye;
③Iziko lokufudumeza lahlulwe ngokwemimandla emihlanu ukufudumeza umbhobho wentsimbi, ukuze iqondo lobushushu lecandelo eliphakathi lombhobho wentsimbi liphakame kunala macala mabini, kwaye liyancipha kwithambeka ukuqinisekisa ukuba irhasi ephakathi umbhobho weplastiki kunye nombhobho wensimbi unokuhamba ukusuka kwindawo ephakathi ukuya kumbhobho wensimbi ngexesha lenkqubo yoxinzelelo.Ukukhutshwa kwiziphelo zombini;
④Isixokelelwano sombane silawula ngokuzenzekelayo isenzo ngasinye seseti yonke yezixhobo, kwaye ilawula ubushushu ngokwenkqubo yokumisela ipharamitha;
⑤ Inkqubo ye-pressurization isebenzisa igesi ephezulu yokucinezela udonga lwangaphakathi lombhobho weplastiki ukuze umbhobho weplastiki wande kwaye udibanise ngokupheleleyo nodonga lwangaphakathi lombhobho wensimbi;
⑥ Inkqubo yokupholisa yesitshizi itshiza kwaye ipholise umbhobho wentsimbi ocinezelekileyo owenziwe ngeplastiki ukuze umbhobho weplastiki umile kwaye udityaniswe ngokuqinileyo nombhobho wentsimbi.
2. Umgaqo-nkqubo wenkqubo kunye nenkqubo yepayipi yensimbi eneplastiki
(1) Umgaqo
Ngokufudumeza umbhobho wentsimbi ofakwe kumbhobho weplastiki, ubushushu bunikezelwa kwi-thermoforming kunye nokudibanisa umbhobho weplastiki owenziweyo, kwaye ke umbhobho weplastiki ucinezelekile ukwenza umbhobho weplastiki wandise kwaye udibanise kunye nombhobho wentsimbi ngokusebenzisa i-adhesive layer.Ekugqibeleni, yenziwe ngokupholisa kunye nokusetha.
(2) Inkqubo yokuhamba
Ukuchithwa kwemibhobho yentsimbi, ukuqhunyiswa kwesanti, ukufakwa kwimibhobho yeplastiki enemigca, iiseti zokubunjwa kwe-pressurization ephezulu, ukufudumeza iziko kunye nokugcinwa kobushushu, ukugcinwa kobushushu, ukukhutshwa kwesithando somlilo, ukupholisa isitshizi kunye nokubunjwa, ukunciphisa uxinzelelo, ukunyanzeliswa kweeseti zokubumba, ukucheba imibhobho ye-terminal, ukuhlolwa. , ukupakisha, ukulinganisa, ukugcina.
3. Iimpawu zenkqubo yepayipi yensimbi eneplastiki
Umbhobho weplastiki kunye ne-adhesive layer iveliswa yi-co-extrusion, kunye ne-hot-melt adhesive layer ihlanganiswe phezu kombhobho weplastiki.Xa umbhobho weplastiki ukhutshiwe, ubukhulu bomgangatho we-adhesive layer kufuneka bufane.Ukufana kobunzima bomgca wokubambelela kunokugwetywa ngokuqwalasela ukuhlukana kwi-reflection yemigangatho emibini yeplastiki ekupheleni kombhobho weplastiki.Imibhobho yeplastiki eveliswayo iyadingeka ukuba ibe nomphezulu ogudileyo kwaye kungabikho agglomeration ngaphakathi kwodonga lombhobho.Ukuphambuka komda wobunzima bodonga kwinqanaba elifanayo aliyi kudlula i-14%, kwaye ubukhulu bomgca wokubambelela buya kulawulwa phakathi kwe-0.2-0.28mm.
Umbhobho wensimbi owenziwe ngeplastiki udibanisa ukusebenza kakuhle kombhobho wentsimbi kunye nombhobho weplastiki, kwaye ixabiso liphezulu kancinane kunombhobho oshushu wokudipha, okuphela kwesinye kwisithathu seendleko zombhobho wensimbi engenasici.Ineenzuzo ezicacileyo ekusebenzeni kweendleko phakathi kwemibhobho emininzi yonikezelo lwamanzi.Ngaphezu koko, kukulungele kwaye kunokwethenjelwa ukufakela kwaye kuye kwaba ngumbhobho ongundoqo wokubonelela ngamanzi amancinci kunye naphakathi.Ngenxa yokuba ingasetyenziselwa ukuthuthwa kwamanzi ashushu, inoluhlu olubanzi lwesicelo kunemibhobho ehlanganiswe ngeplastiki phantsi kweemeko zobugcisa zangoku.
