Njengenxalenye ebalulekileyo yenkqubo yemibhobho yangoku, iplastiki-imibhobho yentsimbi egqunywe kakhulu isetyenziswa kakhulu kwiindawo ezahlukeneyo ekhaya nakumazwe ngamazwe ngenxa yokumelana nokugqwesa kwayo okugqwesileyo kunye nokuqina. Olu hlobo lombhobho lusebenzisa inkqubo ekhethekileyo yokudibanisa ingubo yeplastiki kunye nesiseko sombhobho wensimbi, ukudala umbhobho odibeneyo odibanisa amandla esinyithi kunye neempawu zokukhusela zeplastiki. Umgaqo wayo wokusebenza ufuna ukuphononongwa ngakumbi.
Ngokwesakhiwo, umbindi weplastiki-umbhobho wentsimbi ogqunywe ngumbhobho wentsimbi -owenziwe ngaphambili. Emva konyango olungaphezulu olunjengokususwa komhlwa kunye nephosphating, iplastiki yokwaleka ifakwa ngokulinganayo ngokutshizwa nge-electrostatic okanye kushushu{3}}idiphu yokugquma. Izinto zokugquma eziqhelekileyo ziquka iipolymers ezifana ne-polyethylene (PE) kunye ne-epoxy resin (EP), ezinika ukuzinza okukhethekileyo kweekhemikhali kunye nokuxhathisa ukubola. Xa umbhobho uhambisa ulwelo, isigqubuthelo seplastiki sidibana ngqo nendawo, sithintele ngokufanelekileyo izinto ezidliwayo ezifana namanzi, ioksijini, kunye neeasidi kunye neealkali ukuba zidibane nesiseko semibhobho yentsimbi, ngokusisiseko ilungisa ingxaki yomhlwa eyayanyaniswa nemibhobho yentsimbi yesintu.
Ngokoxinzelelo{0}}lokusebenza, imibhobho yentsimbi egqunywe ngeplastiki{1}igcina ukomelela okuphezulu kwemibhobho yentsimbi. Utyatyazo lweplastiki luqhelekile ukuba nobukhulu be-0.5-3 mm. Ngelixa lincinci, lanele ukwenza umqobo wokukhusela, ngelixa isiseko sombhobho wensimbi sibonelela ngenkxaso yesakhiwo esisisiseko. Esi sakhiwo esidibeneyo sivumela umbhobho ukuba umelane noxinzelelo oluphezulu lokusebenza ngelixa ugcina ukuxhatshazwa kwe-corrosion yeplastiki. Idatha yovavanyo ibonisa ukuba{8}}umbhobho wentsimbi ogqunywe ngeplastikhi ophezulu ungafikelela ekuxhathiseni umhlwa ngaphezu kweminyaka engama-50, ngakumbi xa ungcwatywe phantsi komhlaba okanye kwindawo efumileyo.
Umgaqo wokusebenza weplastiki -umbhobho wentsimbi ogqunyiweyo ukwabonakaliswa kukuguquguquka kobushushu. Iingubo ze-epoxy resin zifanelekile ukuhambisa i-ambient ye-ambient yeqondo lobushushu, ngokwesiqhelo kunye noluhlu lweqondo lobushushu -30℃ukuya kwi-120 degree. Iingubo ze-polyethylene ziyakwazi ukumelana namaqondo aphantsi kwaye zisetyenziswa ngokubanzi kwiindawo ezibandayo ezisemantla. Iplastiki -imibhobho yentsimbi egqunywe ngentsimbi, eveliswe kusetyenziswa inkqubo ekhethekileyo, inokumelana{8}}nezothuso zexesha elifutshane lobushushu obuphezulu, ukuhlangabezana neemeko zokusebenza ezinzima zemibhobho yeshishini.
Ukusuka kwimbono yesicelo, umgaqo wokusebenza weplastiki -umbhobho wentsimbi ogqunyiweyo wenza ukuba ifaneleke ngokukodwa ukubonelela ngamanzi kunye neenkqubo zokuhambisa amanzi, imibhobho yokukhusela umlilo, kunye nokuthuthwa kwamanzi amachiza. Kwiinkqubo zokubonelela ngamanzi, iplastiki yokugquma ithintela ngokufanelekileyo ukukhula kwebhaktheriya; kushishino lweekhemikhali, ukuxhathisa kwayo kweekhemikhali kuqinisekisa{2}}ixesha elide kunye nokusebenza okuzinzileyo kwenkqubo yemibhobho. Ngophuhliso lolwakhiwo lweziseko ezingundoqo zehlabathi, esi sicombululo semibhobho esisebenzayo nesoqoqosho sifumana ukuqondwa ngakumbi nangakumbi kwimarike yamazwe ngamazwe.
