Kwihlabathi elihlala liguquka lolwakhiwo nobunjineli, ukufumana imathiriyeli eyomeleleyo kwaye eyomeleleyo kubalulekile. Phakathi kwezinto ezintsha eziye zavela kwiminyaka yamuva nje, imibhobho ene-polyurethane-lined ifumene ingqwalasela enkulu ngenxa yokukwazi ukuphucula ukuqina kwemibhobho yesakhiwo esingenanto. Eli nqaku liphonononga indlela ukuhlanganiswa kwe-polyurethane linings kunokuguqula la macandelo esakhiwo, okwenza kube lula kwaye kusebenze kwiinkqubo ezahlukeneyo.
Imibhobho yesakhiwo yecandelo elingenamgongxo isetyenziswa ngokubanzi kulwakhiwo, iziseko ezingundoqo kunye namacandelo oshishino ngenxa yobume be-tubular kunye nobukhulu bodonga obufanayo. Zenzelwe ukuhanjiswa kwemithwalo ngokufanelekileyo kwaye zilungele ukuxhasa izakhiwo ezifana neebhulorho, izakhiwo kunye ne-scaffolding. Nangona kunjalo, omnye wemicelimngeni ejongene nale mibhobho kukuchaphazeleka kwayo kukudleka, ukuguga nokugruzuka, ngakumbi kwiindawo ezirhabaxa. Apha kulapho iileyile ze-polyurethane zingena khona
I-Polyurethane yipolymer eguquguqukayo eyaziwayo ngeempawu zayo ezibalaseleyo zoomatshini, kubandakanya ukomelela okuphezulu, ukuguquguquka, kunye nokumelana neekhemikhali kunye nezinto zokusingqongileyo. Xa i-polyurethane isetyenziselwa umgca wemibhobho yesakhiwo secandelo elingenalutho, idala umqobo wokukhusela owandisa kakhulu ukuqina kombhobho. Olu luhlu alugcini nje ukuthintela ukubola okubangelwa ngumswakama kunye neekhemikhali, kodwa kunciphisa ukuguga kwii-abrasives, ukwandisa ubomi benkonzo yombhobho.
Enye yeenzuzo ezibalulekileyo zeumbhobho owenziwe nge-polyurethanekukukwazi ukumelana neemeko ezinzima. Kumashishini afana nemigodi, i-oyile kunye negesi, kunye nolawulo lwamanzi amdaka, imibhobho ihlala ibonakaliswe kwizinto ezinobungozi kunye nezinto ezinobungozi. I-polyurethane lining isebenza njengesithintelo, ukukhusela isinyithi esingaphantsi ekuthotyweni kunye nokuqinisekisa ukuba ukunyaniseka kwesakhiwo sombhobho kuhlala kunjalo. Oku kuhlala kuthetha iindleko eziphantsi zokugcinwa kunye nexesha eliphantsi lokunciphisa, ukwenza umbhobho owenziwe nge-polyurethane ube sisisombululo esingabizi kakhulu kumashishini.
Ukongeza, iipropathi ezikhaphukhaphu ze-polyurethane zenza umbhobho wolwakhiwo wecandelo elinomngxuma ube lula ukuphatha nokuwufaka. Iimathiriyeli zemveli zinokuba nkulu kwaye kube nzima ukusebenza nazo, okukhokelela ekunyukeni kweendleko zabasebenzi kunye neeshedyuli ezandisiweyo zeeprojekthi. Ngokwahlukileyo, umbhobho owenziwe nge-polyurethane kulula ukuthutha nokufaka, ukulungelelanisa inkqubo yokwakha kunye nokuphucula ukusebenza kakuhle kweprojekthi.
Omnye umba omkhulu wemibhobho eyenziwe nge-polyurethane kukuguquguquka kwazo. Ziyakwazi ukulungelelaniswa kwiimfuno ezithile, kubandakanywa ubukhulu obuhlukeneyo be-lining, amabakala ahlukeneyo e-polyurethane, kunye nobukhulu obuqhelekileyo betyhubhu. Oku kulungelelaniswa kubenza bafanelekele uluhlu olubanzi lwezicelo, ukusuka kulwakhiwo lweendawo zokuhlala ukuya kwiiprojekthi ezinkulu zoshishino.
Ukongeza kwiinzuzo ezisebenzayo, iipayipi ezifakwe kwi-polyurethane nazo zinegalelo kuphuhliso oluzinzileyo. Ngokwandisa ubomi benkonzo yemibhobho yesakhiwo kunye nokunciphisa imfuno yokutshintshwa rhoqo, ezi nguqulelo zinceda ukunciphisa inkunkuma kunye nokusetyenziswa kwemithombo. Ukongezelela, iinkqubo zokuvelisa amandla ezihambelana ne-polyurethanes zinceda ukunciphisa i-carbon footprints, ehambelana nokugxininisa okukhulayo kwizenzo zokwakha ezizinzileyo.
Isishwankathelo, ukuhlanganiswa kwe-polyurethane linings kwimibhobho yesakhiwo secandelo elingenalutho kubonisa ukuqhubela phambili okubonakalayo kwithekhnoloji yezixhobo. Ngokwandisa ukuqina kunye nokubonelela ngokhuseleko kwi-corrosion kunye ne-abrasion, iipayipi ezifakwe kwi-polyurethane zitshintsha i-landscape yokwakha kunye nobunjineli. Njengoko amashishini eqhubeka efuna izisombululo eziphucula ukusebenza ngelixa kuncitshiswa iindleko, ukwamkelwa kwemibhobho efakwe i-polyurethane kunokwenzeka ukuba ikhule, ivule indlela yokuqina kunye neziseko ezisebenzayo.
