Imibhobho ye-polyurethane isetyenziswa ngokubanzi kwimizi-mveliso yokuthutha ulwelo, ukuveliswa koomatshini, kunye nokwakhiwa ngenxa yokunganyangeki kwabo okugqwesileyo, ukuxhathisa imichiza, kunye nokuguquguquka.Nangona kunjalo, ukusetyenziswa ngokufanelekileyo kunye nokugcinwa kwemibhobho ye-polyurethane kubalulekile ekuqinisekiseni ukusebenza kwabo kunye nobomi babo, ngakumbi kurhwebo lwamazwe ngamazwe. Ababoneleli kunye nabathengi kufuneka banike ingqwalasela enkulu kula manqaku alandelayo:
Okokuqala, imibhobho ye-polyurethane ivakalelwa kubushushu. Ukuboniswa{1}ixesha elide kumaqondo obushushu aphezulu kakhulu okanye asezantsi kunokubangela ukuba izinto zibe lukhuni okanye zibe brittle. Uluhlu lweqondo lokushisa olucetyiswayo ngokubanzi ngu-40℃ukuya kwi-80 degree; ukugqitha kolu luhlu kunokuchaphazela iipropati ezibonakalayo zombhobho. Ngoko ke, ngexesha lokuthutha kunye nokugcinwa, ukukhanya kwelanga kunye nokusondela kwimithombo yokushisa kufuneka kugwenywe, kwaye iqondo lokushisa elizinzileyo kufuneka liqinisekiswe.
Okwesibini, imibhobho ye-polyurethane iyakwazi ukuva ioyile, izinyibilikisi, kunye neeoksijini ezinamandla. Ukudibana nezi zinto kunokubangela ukwanda, ukuqhekeka, okanye ukuthotywa komgangatho wokusebenza. Xa ukhetha umbhobho, ukuchasana kweekhemikhali kwezinto kufuneka kuqinisekiswe ngokusekelwe kwimeko yesicelo esithile, kwaye ukudibanisa ngokuthe ngqo kunye neendaba ezingahambelaniyo kufuneka kugwenywe. Ukuthuthwa kwamanzi amdaka kakhulu, kuyacetyiswa ukuba ukhethe imibhobho ye-polyurethane ephathwa ngokukodwa okanye udibane nomthengisi ngezinye iingcebiso.
Ngaphezu koko, ukufakela kunye nokusetyenziswa kwemibhobho ye-polyurethane kufuneka kugweme ukugoba ngokugqithiseleyo okanye ukunyanzeliswa kokuthintela umonakalo kwindonga yangaphakathi okanye ukungaphumeleli kwesakhiwo. Xa isetyenziswa kwindawo -zoxinzelelo oluphezulu, qinisekisa ukuba izinga loxinzelelo lombhobho lihlangabezana neemfuno zenkqubo kwaye uhlole rhoqo iimpawu zokuguga okanye ukuguga.
Kwiintengiselwano zorhwebo zamazwe ngamazwe, umthengi kufuneka axelele ngokucacileyo umthengisi wemeko yesicelo esithile, kubandakanywa uhlobo lwe-fluid, uluhlu lweqondo lokushisa, kunye neemeko zoxinzelelo, ukuqinisekisa ukunikezelwa kweemveliso ezifanelekileyo. Ngaxeshanye, amanyathelo othuso kufuneka athathwe ngexesha lokupakishwa kunye nokuthuthwa ukunqanda imikrwelo yomphezulu okanye umonakalo owenziwe ngaphakathi owenziwe lungquzulwano ngexesha{1}}lohambo lomgama omde.
Ukuqukumbela, izibonelelo zokusebenza zemibhobho ye-polyurethane zifuna ukusetyenziswa ngokufanelekileyo kunye nokugcinwa kokuqinisekisa ukusebenza kwazo. Bobabini ababoneleli kunye nabathengi kufuneka baziqonde ngokupheleleyo iimpawu zabo zokuqinisekisa ukuba imveliso ihlala ikwimeko efanelekileyo kulo lonke uthutho, ukugcinwa, kunye nokusetyenziswa, ngaloo ndlela iphucula ukuthembeka kunye nokwaneliseka kwentsebenziswano yorhwebo.
