Umcu wokutywina onganyangekiyo kubushushu obuphezulu ubhekisa kwisixhobo sokutywina esinokuthi sibe nokusebenza kakuhle kokutywinwa kwindawo yobushushu obuphezulu.Uluhlu lwesicelo lwayo lubanzi kakhulu, kwaye lusetyenziswa ngokubanzi kwiinkalo ezininzi ezifana ne-aviation, i-aerospace, i-automobile, i-electronics, i-petrochemical industry kunye nokunye.
Okokuqala, kwiinkalo zenqwelomoya kunye ne-aerospace, imicu yokutywina ekwaziyo ukumelana nobushushu obuphezulu isetyenziselwa ukutywina izihlandlo zobushushu obuphezulu njengee-injini zomoya, iinjini zerokethi, kunye nemijukujelwa.Kwezi ndawo zinzima, izinto zokutywina zifuneka ukuba zibe nokumelana nobushushu obuphezulu, ukumelana noxinzelelo oluqinileyo, ukuxhathisa ukubola kweekhemikhali kunye nezinye iimpawu zokuhlangabezana neemfuno ezingqongqo.
Okwesibini, kwintsimi yokwenziwa kweemoto, imichilo yokutywina enokumelana nobushushu obuphezulu isetyenziselwa ukutywina izinto ezinobushushu obuphezulu njengeenjini, iibhokisi zegiya, iinkqubo zokupholisa, iinkqubo zokuthatha, kunye neenkqubo zokukhupha.Ezi zixhobo ziya kuvelisa ubushushu obuphezulu ngexesha elide lokusebenza kwesantya esiphezulu, kunye nemichilo yokutywina yokumelana nobushushu obuphezulu iyafuneka ukuze kutywinwe ukuqinisekisa ukhuseleko kunye nokuthembeka kwemoto.
Ukongeza, kwintsimi ye-electronics, iintambo zokutywina ezinobushushu obuphezulu zisetyenziselwa ukutywina izicelo zokushisa eziphezulu ezifana nokuveliswa kwe-semiconductor, i-optoelectronics, umbane kunye nezixhobo zombane.Kule mimandla, izinto zokutywina zifunekayo ukuba zibe nokumelana nokushisa okuphezulu, ukuxhathisa ukubola, ukuqhutyelwa kwe-thermal conductivity kunye nezinye iimpawu.
Okokugqibela, kumzi-mveliso wepetrochemical, imichilo yokutywina enganyangekiyo kubushushu obuphezulu isetyenziselwa ukutywinwa kwindawo yobushushu obuphezulu njengokucocwa kweoyile kunye neshishini lemichiza.Kwezi ndawo zigqwesileyo, izinto zokutywina ziyafuneka ukuba zibe neempawu ezinjengokumelana ne-corrosion, ukumelana nokunxiba, kunye nokumelana nobushushu obuphezulu.
Ngamafutshane, imicu yokutywina enokumelana nobushushu obuphezulu inoluhlu olubanzi lwezicelo.Kwiindawo ezigqithisileyo ezibandakanya ukushisa okuphezulu, uxinzelelo oluphezulu, kunye nokubola, izinto zokutywina zidlala indima ebalulekileyo ukuqinisekisa ukhuseleko, ukuthembeka kunye nokuzinza kwezixhobo.
Imicu ye-Styrofoam inokusetyenziselwa ukutywinwa kwezixhobo zombane, kwaye zineziphumo zokubopha, ukutywinwa, ukubuyiswa komlilo kunye nokungangeni kwamanzi, ngoko ke abaninzi abavelisi bemveliso yerabha yesiko basebenzisa olu hlobo lwemicu yamagwebu xa besenza izixhobo zombane, kwaye ngamanye amaxesha iya kusetyenziselwa. ukutywinwa kwezinto zombane.Kwithiyori, i-polyurethane foam strips inokudlala indima ekutywineni, ekuthinteleni amanzi, kunye nokuncipha komlilo, kodwa umphumo awunelisi emva kokusebenza kwangempela.Ke siyintoni isizathu sesiphumo esibi samanzi semicu ye-foam?
Ngapha koko, umcu werabha we-polyurethane foam unomgangatho olungileyo wokungangeni kwamanzi kunye nokutywinwa.Ukuba umqhubi akanamava aneleyo okanye itekhnoloji yokusebenza ayifaniswanga ngexesha lomsebenzi wokwenene, iya kubangela ukuba umtya werabha we-polyurethane foam ungasebenzi emva kokunyanga.Isiphumo esihle sokungangeni manzi, okanye isiphumo esibi samanzi.Ukongezelela, ekusebenzeni kwangempela, ukuba umphezulu oza kudibaniswa awuhlambulukanga, umphumo uya kuba mbi emva kokunyanga, umphumo olindelekileyo wokungena kwamanzi awuyi kufezekiswa, kwaye ubomi benkonzo buya kuncitshiswa.
