Njengodidi olutsha lombhobho oyintlanganisela, imibhobho yentsimbi egqunyiweyo yeplastiki isetyenziswa kakhulu kumashishini ahlukeneyo ngenxa yokumelana nokugqwesa kwawo, ukomelela koomatshini, kunye nobomi benkonzo. Umgangatho wabo wangaphakathi nangaphandle uphathwa ngeplastiki ekhethekileyo, engagcini nje ukwandisa ukuxhathisa ukubola kombhobho kodwa iphinde iphucule ukuxhatshazwa kwayo kunye nokunyanzeliswa koxinzelelo, okwenza ukuba ilungele ukusetyenziswa kwiindawo ezahlukeneyo eziyinkimbinkimbi.
Kwicandelo loshishino, iplastiki -imibhobho yentsimbi egqunyiweyo iqhele ukusetyenziswa kwimichiza, i-petroleum, kunye namashishini ombane. La mashishini ahlala ebandakanya ukuthuthwa kweendaba eziqulethe i-acids eqinile, i-alkali enamandla, okanye ukushisa okuphezulu kunye noxinzelelo oluphezulu. Imibhobho yentsimbi eqhelekileyo iyakwazi ukubola, inciphisa ubomi babo benkonzo. Ukwaleka kweplastiki yeplastiki-yemibhobho yentsimbi egqunyiweyo ihlukanisa ngokufanelekileyo imidiya edlekayo kwaye ikhusela isubstrate yombhobho wentsimbi, ngokwenjenjalo iqinisekisa{5}}ixesha elide kunye nokusebenza okuzinzileyo kwenkqubo yombhobho. Umzekelo, kwimveliso yeekhemikhali, iplastiki{7}}imibhobho yentsimbi egqunyiweyo ingasetyenziselwa ukuthutha ulwelo oludlekayo okanye iigesi ezifana ne-asidi yesulfuric kunye ne-hydrochloric acid. Kwishishini lamandla, zifanelekile kwityhubhu yokukhusela ikhebula, ukubonelela ngokugqwesileyo kunye nokukhusela.
Ubunjineli bakamasipala bukwasisicelo esingundoqo seplastiki-yemibhobho yentsimbi egqunywe ngentsimbi. Unikezelo lwamanzi asezidolophini, ukuhanjiswa kwamanzi, ukuhanjiswa kwerhasi, kunye nezinye iinkqubo zifuna ukuxhathisa okuphezulu kwe-corrosion kunye neempawu zococeko zemibhobho yazo. Iplastiki-imibhobho yentsimbi egqunywe ngentsimbi ineendonga ezigudileyo zangaphakathi ezimelana nokukalwa, ngokufanelekileyo zicutha ukuxhathisa ukuhamba kwamanzi, ukuphucula ukuhanjiswa kwamanzi, kunye nokuthintela ukungcoliseka kwamanzi. Ngaphaya koko, i-coat yabo yangaphandle inika ukuxhathisa kwemozulu okugqwesileyo, ikhusela kwimitha ye-UV, ukufuma, kunye nezinye iimpembelelo zokusingqongileyo, izenza zilungele ukufakwa phantsi komhlaba kunye -nomoya ovulekileyo.
Kushishino lokwakha, iplastiki -imibhobho yentsimbi egqunyiweyo isetyenziswa ngokuqhelekileyo kwiinkqubo zokukhusela umlilo, imibhobho yomoya ophakathi, kunye neenkqubo zokufudumeza umgangatho. Imibhobho yokhuseleko lomlilo kufuneka imelane{2}noxinzelelo oluphezulu lokuhamba kwamanzi, kunye nesakhiwo esomeleziweyo kunye{3}}nemibhobho yokuncamathelisa ephezulu yeplastiki{4}}imibhobho yentsimbi egqunyiweyo ibenza bakwazi ukumelana nolu xinzelelo luphezulu lo gama ikhusela umhlwa kunye nomgangatho wamanzi. Umoya womoya ophakathi kunye neenkqubo zokufudumeza umgangatho zifuna imibhobho ene-thermal egqwesileyo kunye nokumelana nokubola, apho iplastiki{6}}imibhobho yentsimbi egqunyiweyo idibana, yandisa ubomi benkonzo yenkqubo.
Iplastiki -imibhobho yentsimbi egqunywe ngentsimbi ifanelekile kwizicelo ezikhethekileyo ezifana nokusingqongileyo elwandle, imigodi, kunye nokunkcenkceshela kwezolimo. Kwiindawo zaselwandle, imibhobho yentsimbi eqhelekileyo ichaphazeleka kukuhlwa kwetyuwa, ngelixa i-anti{2}}i-corrosion coating yeplastiki{3}}yemibhobho yentsimbi egqunyiweyo imelana ngokufanelekileyo nohlaselo lwe-ion ye-chloride. Kwimigodi, banokuhambisa imidiya eyingozi kakhulu efana ne-slurry. Ekunkcenkcesheleni kwezolimo, ukuxhathisa kwazo kumhlwa kuqinisekisa{6}}usetyenziso lwexesha elide ngaphandle kokuchatshazelwa bubulunga bamanzi.
Lilonke, iplastiki -umbhobho wentsimbi egqunyiweyo uye wasisicombululo semibhobho eyimfuneko kumashishini amaninzi ngenxa yeenzuzo zawo ezininzi. Nokuba kumashishini, kumasipala okanye kumacandelo okwakha, inokubonelela ngenkqubo yemibhobho ethembekileyo nehlala ixesha elide ukuhlangabezana neemfuno zeemeko ezahlukeneyo.
