Njengoko i-polyurethane i-foam eqinile (i-PU eqinile i-foam) ineempawu zobunzima bokukhanya, i-thermal insulation effect, ulwakhiwo olulula, njl. ukumelana, njl., isetyenziswe ngokubanzi ekhaya nakwamanye amazwe.Kwi-aerospace, ukwakhiwa kweenqanawa, i-petroleum, izixhobo zombane, izithuthi, ukutya kunye namanye amacandelo oshishino.
Ukusetyenziswa okuphambili kwe-PU ye-foam eqinile ngolu hlobo lulandelayo:
1. Izixhobo zokukhenkceza zezixhobo zekhaya kunye nemizi-mveliso yokutya
Iifrijikunye nezikhenkcezisi ezisebenzisa ugwebu oluqinileyo lwePU njengoko umaleko wokugquma unomaleko obhityileyo wokugquma.Ngaphantsi kwemilinganiselo yangaphandle efanayo, umthamo osebenzayo mkhulu kakhulu kunokuba ezinye izinto zisetyenziswe njengoluhlu lwe-insulation, kwaye ubunzima besixhobo buyancitshiswa.
Izifudumezi zamanzi zasekhaya, izifudumezi zamanzi elanga, kunye ne-beer keg interlayers ngokuqhelekileyo zisebenzisa izinto eziqinileyo zokugquma amagwebu e-polyurethane.I-PU eqinile igwebu iphinda isetyenziswe ekwenzeni ii-incubators eziphathwayo zokuthutha iimveliso zebhayoloji, amayeza kunye nokutya okudinga ukugqunywa kwe-thermal kunye nokugcinwa.
2.Izixhobo zoshishino kunyeumbhobhoukugquma
Amatanki okugcina kunyeimibhobhozixhobo eziqhelekileyo ezisetyenziswa kwimveliso yemizi-mveliso, kwaye zisetyenziswa kakhulu kwi-petroleum, igesi yendalo, ukucokisa i-oyile, ishishini lemichiza, ishishini lokukhanya kunye namanye amashishini.Ubume betanki yokugcina i-spherical okanye i-cylindrical, kwaye i-PU eqinile i-foam inokwakhiwa ngokutshiza, ukugalela kunye nokuncamathisela i-foam eyenziwe ngaphambili.Njengeumbhobhoimathiriyeli yokugquma i-thermal, isetyenziswa ngokubanzi ukufakwa kwe-thermal kwimibhobho ekuthuthweni kwe-oyile ekrwadaimibhobhokunye namashishini epetrochemical, kwaye iye yatshintsha ngempumelelo izixhobo ngokufunxa amanzi aphezulu njengeperlite.
3. Izinto zokwakha
Ukwakhiwa kwezindlu yenye yezona ndawo zibalulekileyo zesicelo se-PU eqinile ye-foam.E-China, i-foam eqinile iye yaziwa ngokufakwa kwe-thermal kunye nokukhusela amanzi kuphahla lwezindlu zokuhlala kunye nezakhiwo zeofisi,Ukwakha imathiriyeli ye-Insulation, kunye ne-thermal insulation materials forigumbi elibandayo, iindawo zokugcina ukutya okuziinkozo, njl njl. I-foam ekhuni etshisiweyo isetyenziselwa uphahla, kunye noluhlu olukhuselayo longezwa, olunemiphumo emibini ye-thermal insulation kunye nokukhusela amanzi.
I-polyurethane eqinileiipaneli zesandwichzisetyenziswa kakhulu kwizityalo zoshishino, iindawo zokugcina iimpahla, amabala emidlalo, iindawo zokuhlala, iivillas, izindlu ezakhiwe ngaphambili kunye nezidityanisiweyo.igumbi elibandayo, njengeepaneli zephahla kunye neepaneli zodonga.Ngenxa yobunzima bayo obulula, ukugquma ubushushu, ukungangeni kwamanzi, umhlobiso kunye nezinye iimpawu, kunye nokuhamba kakuhle (ufakelo), inkqubela phambili yokwakha ngokukhawuleza, ithandwa kakhulu phakathi kwabaqulunqi, ukwakhiwa kunye nabaphuhlisi.
Uxinaniso oluphezulu (uxinzelelo 300~700kg/m3) I-PU igwebu elomeleleyo okanye ifayibha yeglasi eyomeleziweyo ugwebu oluqinileyo yiplastiki yolwakhiwo lolwakhiwo, ekwaziwa ngokubaiplanga.Inokutshintsha umthi njengeeprofayili ezahlukeneyo zomgangatho ophezulu, iibhodi, iimpahla zemidlalo, izinto zokuhombisa,ekhayaifenitshala,izakhelo zesipili,trowel,Ibhedi yentloko ,iprosthesis,upholstery,izincedisi zokukhanyisa, kunyeukulinganisa umthi wokukrola imisebenzi yezandla, njl., kunye nenkangeleko kunye nombala weemveliso unokulungelelaniswa ngokweemfuno, ezinombono obanzi wemarike.I-foam eqinile yesakhiwo eyenziwe ngokongeza i-flame retardant inokukhanya okuphezulu kakhulu kunomthi.
Ukubumba isithsabakunye nemigca ye-plaster yomibini imigca yokuhlobisa yangaphakathi, kodwa izinto zokuvelisa kunye nokwakhiwa zihlukile.Imigca yePU yenziwe ngezinto zokwenziwa zePU.Yenziwe ngoxinzelelo oluphezulu lwegwebu lepolymer, kwaye yenziwe nge-pu foam eqinile.Le pu foam engqongqo ixutywe kunye namacandelo amabini ngesantya esiphezulu kumatshini wokucoca, kwaye emva koko ingena kubumba ukwenza kunye nokwenza.I-epidermis enzima.Ayinatyhefu kwaye ayinabungozi, ihambelana kakhulu nokusingqongileyo.
Ukubumba isithsabaazikhubekanga, aziqhekeki, okanye azibolanga;ukumelana ne-corrosion, i-asidi kunye nokumelana ne-alkali, kwaye inokugcina ukuzinza kwezinto eziphathekayo unyaka wonke.Akudliwa linundu, nantubi;akukho manzi afunxayo, akukho manzi, anokuhlanjwa ngokuthe ngqo.Ukufakwa kwe-thermal ephezulu, yimveliso egqwesileyo yokufakelwa kwe-thermal, ayiyi kuvelisa iibhulorho ezibandayo kunye nobushushu.
Impahlaiimannequinsyintsimi entsha yesicelo kwishishini le-polyurethane.Iimodeliyenye yezinto ezibalulekileyo kwivenkile yempahla.Bayakwazi ukunxiba ivenkile kwaye babonise izinto eziphambili zempahla.Iimodeli zempahla ezikhoyo kwimarike zenziwe ngefiberglass fiber, iplastiki kunye nezinye izinto.Ifiberglass ifayibha ayinakunganxibi kakuhle, inobunkunkqele, kwaye ayinakunwebeka.Iiplastiki zineziphene ezifana namandla aphantsi kunye nobomi obufutshane.Imodeli yengubo ye-polyurethane ineenzuzo zokumelana nokunxiba kakuhle, amandla alungileyo, ukuqina, ukusebenza kakuhle komgangatho, kunye nenqanaba eliphezulu lokulinganisa.
7.Okunye isicelo esiqhelekileyo
Ukongeza kwezi zicelo zingentla, i-polyurethane eqinile igwebu inokusetyenziselwa ukuzaliswa kocango kunye nokuveliswa kweebhola ezidadayo zeentlanzi, njl.
Umnyango ogcwele i-polyurethane foam ubonakala ufana naluphi na olunye ucango, nangona kunjalo, isakhiwo sangaphakathi sahluke ngokupheleleyo.Ngokuqhelekileyo umnyango ongenapeyinti uvulekile ngaphakathi, okanye uzaliswe ngephepha le-honeycomb, ngelixa i-polyurethane eqinile egcwele i-foam umnyango ayihlaza kakhulu kwaye ihambelana nokusingqongileyo, kodwa iqinisa ukuqina kwesakhelo socango, okwenza umnyango ube namandla kakhulu kwaye womelele. , nokuba luxinzelelo lwento enzima, amaqamza amanzi, Nokuba itshiswe emlilweni, inokuqinisekisa ukuba ayisoze ikhubazeke.Le teknoloji iphelisa iingcango ezidibeneyo, iingcango zokhuni zithandwa kakhulu kwiingxaki ezifana nokuguqulwa kunye nokufuma.
