I-solid rigid polyurethane foam yimbali engcono kunye nobuciko. Ngokuba yakwazi ukulanda indawo ezininzi kunye nokuphazamiswa kunye nokuphindezelwa ngaphandle kokubhedelela. Kwiindlela eziningi, kusukela kuhlanganiswa kwezindlu kwiqhosha lezinto eziphathelwe ngaphandle kokubhedelela. Yabelwe ngonyaka 1950, kodwa ngokusasa amaxesha angaphambili abelwe amanye amandla apha ongabizwa ukubuyiselwa umoya womoya womtsha kunye nokubuyiselwa umoya wemibala esiqhelekileyo. Manje, benza siyiceba indlela yayo kanye nokuba kuphi sifuna kwindawo yokugcina labo.
Iyo yilungiselelwa ngemibubhesi eminingi elincinci elihlukileyo ezichaswe kwindawo elithile. Amabubhezi amaningi amahluke kakhulu ngenxa yokuba zizifuneka ukufika umoya, ndabezona uqondela ukuba kusuke kuhlala ngendawo enye, kodwa ingxenyiso yayo yenza imigca esingabo. Ukugcwalisa nokulula kumigca kunokuthi le nto iyiphakamisanga ngaphandle kokuba kukhethwe (liyayityetiswa ngokupheleleyo kwiqhobo lomthombo). Baye abahlali babenjalo bafuna ukusetshenziswa ngoba ungene ukwenza imigomo engaphezulu kudla ngaphandle kokucabanga. Ngokuhlelo lokho, le mfowethu wenza uphawu olungileyo kakhulu, ndabezona ungene ukwenza ukusebenziswa ukuvumela ukuncedisiweyo okanye ukuxhasa ukuya kumbuso.
Ngokulandelayo, yinto elungileyo ngeMphathiso wesithuthi esisindileyo polyurethane nguqukethwe ukuba ubhekene nomthimba. Ukuthi lokhu kuyahlala amaxhobo akhe ayiqhele ngemvula emoyeni nokuhlala ezintshangeni ezincinci phambi komoya omkhulu. Ngokuvamile, xa lokho lumphathiso luhlanganiswa phakathi kwamabezu nokubhedliseko labe, kufuneka kube yinto engenayo ukusuka kumhlaba kunye nokuhlala ekuphakamisweni lapho kukuba umsebenzi wakho uqhubele ngendlela efanelekayo. Lokhu liyindlela yokugcina izifundazwe zokuthi zihlale ngokuqinile kumaqhele amanye ahluke xa kunye nomoya omkhulu nokuthi zihlale ngokushaya xa kunye nomoya omkhulu.
ISANYING Solid rigid polyurethane foam uyasebenziswa ngokubanzi kwiqhutywa lemaxabiso amabini. Leliqhutyu lusebenziswayo ukuphakamisa izinto ezincinci, njengomgciyo nokulungileyo, ukusurela ukuba zikhona ngaso ngenxa yokuqala kwesixhasa. Xa liqhutyu lifumane amaxabiso, ilizwe lakho lingenzi lokuhlola. Iliqhutyu linceda isibhedlela, ngoko xa iphepha libekelwe, iliqhutyu lilindise amaxabiso apho ahlola ukusuka kwisebenza. Ngoko ke, yintoni okunyelekelwa ngamaxesha iindlela zakho. ipolyurethane yamaphu zokungqinisekisa yasebenziswa ngokuphakamisela ngoba ulula ukuya kuqaphela izintsha kuhlanganiswa ngasemva semva.
Ifomu yesi PU esisetyenziselwa kufuneka siphumelele iimboniso zokulayisha. Ingxenyeko lokulayisha ixhobo lwezinto ezilayishwayo, kunokuyenza ukuba umoya omkhulu wexhobo uhlale ngendawo yokugcina okanye yokuhlala. Ukulayisha oluhle kuxhasa ukuba izixhobo zihlinze inani lesikhatsi sokubuya nokuhlala. Lokhu akukho ngenxa yokuqinisekiswa kwesikhephe, kodwa kukho imveliso eliphiyo ngaphandle kokuthi kufunekwe ukuphucula nokuhlala. Ngokushesha, ifomu iyeyiphi lezi zinto ezizibophelela, iphophonte isebenzisa ukubuyela ukusuka kuzo kumahluko.
SANYING Solid rigid polyurethane foam and ifomu yesi polyurethane esikhulu yasebenzisa nazo manje ngokwemva kweentsha. Iintsinga zakhe zifundiswa ukuba zivamile amasitsa, amacushon ngeke namandla apha ukuba abe ngaphandle komoya obuncinci. Ngoko ke, kuloo mncedo okanye iicheyi ziyinkethu zimbini. Ngoba yakhe ingxenye ngenkxaso kunye neqingatha, izinga lokulayisha zaziphuma ngendawo lokungabangene ngokubanzi. Ngenxa yalokho, abantu bazibophelela ngazo zintsha zabo ngonyaka ezininzi.
SANYING Solid rigid polyurethane foam also the isisophani polyurethane ukunyuzwa kakhulu emasiphephakini ngamandla ezininzi. Umthwalo omncane wokuqalaba uhlale ukususa imali yokuthumela, okungokuhle kwezisebenzisi kunye nezikhankatha zonke. Nangoko ubuciko babo buphi, ngakho bayigcizelela amagunya apho aqhutywa phakathi kwesixhasi. Iindlela zokugcwalisa zeqhayisana zingabizwa ukubuyiselwa umoya wemibala esiqhelekileyo njengebhafo lokuhlala ngenqanawe, njengomoya womtsha. Lokunye kukaqiniso lokuncedisiyo lwenqanawe.
