Wathi polyurethane foam kuyinto sealant eyodwa ingxenye esekelwe polyurethane kwakhiwa. Ngemva yokufuna wayethethelela ngokushesha ingasetshenziswa. Esikhathini inqubo yokusebenzisa izingxenye polymerize, uxhumana izinhlayiya we umswakama eziqukethwe imvelo bangaphandle. Polyurethane foam uye ilangabi cishe yizona ezisetshenziswa kabanzi izithako zihlanganisa izinto ezithile ezihlinzeka izimfanelo aphakeme acoustic futhi ezishisayo. Ezakhiwe ungqimba eliqinile ngokuphelele igesi futhi intuthu.

Foam Izici

Polyurethane foam akabi cishe yizona ezisetshenziswa e ngqo umlilo ukuchayeka isikhathi esithile ngumkhiqizi. Ngemuva kwesicelo akusho flow phansi ngisho noma kubonakala endaweni mpo. Phakathi izici zayo ezinhle zihlanganisa ikhono ugcwalise isikhala yanoma iyiphi ifomu. Unamathela kahle ukuba evele isitini lezisekelo ezenziwe ngokjuni, polymer, usimende, steel namabhodlela.

Indaba enokumelana okuhle amanzi isikhunta unekhono nezinguquko lokushisa kule uhla kusuka -60 kuya +100 ° ^C. Kaningi, ikhaya izingcweti nabakhi kuqhathaniswa izinto ezichazwe analogs ezithinta izakhiwo bendabuko. Kule mpi, winner uyaphuma inguqulo yokuqala kephunkephu it okuhlala isikhathi eside futhi ethembekile.

Polyurethane foam ilangabi cishe yizona ezisetshenziswa kabanzi kungase kudingeke isikhathi ezahlukene ngaphambi okwamanje ukuthungela. Ngokwesibonelo, Soudal brand impahla kanye nomthelela ngqo elangabi ngeke ashise imizuzu 360. Sinazo ikhono foam samougasaniyu. Lokhu kubonisa ukuthi Foam ilangabi cishe yizona ezisetshenziswa kabanzi, futhi uma ziyobhekana umlilo ngqo, ngeke akha iconsi ashisayo. Ngesikhathi ukususwa Foam ilangabi wedwa damped. Njengoba umuntu angabona ukuhlukanisa ukuzwela ukuntula elangeni. Yingakho Foam kudinga Ukuvikelwa emva uthele.

imithetho isicelo

Polyurethane foam ilangabi cishe yizona ezisetshenziswa kabanzi ozofakwa kwamanzi, lapho izinga lokushisa zokhahlamba kusuka +5 ukuba +30 ^° C yokusebenza lokushisa okuqukethwe sangaphakathi isitsha akufanele idlule ukulinganiselwa +10 ukuba + 30 ^° C. Ukuze ukulungiselela Foam ukusetshenziswa, it kumele agcinwe ekamelweni lokushisa, kodwa awukwazi sishiswa ngakho. Isitolo amasilinda Kunconywa ababhemayo, ukubeka intamo up.

Cishe yizona ezisetshenziswa kabanzi polyurethane foam inhlangano phambi isicelo kufanele ayonyakaziswa kahle. Khona-ke kubalulekile ukuba ahlaziye kahle kanjani iphume ibhodlela. Ngemva sinjalo, okukhiphayo uyamukeleka iqale ukusebenza. Ukuze kuzuzwe adhesion kangcono, kubalulekile ukuba moisten surface ukusebenza ngamanzi. Nokho amaconsi phezu akufanele kube. Izimbotshana akudingeki ukugcwalisa ezingaphezu kuka 1/3. Ngemva Foam usuku kufanele ukuqoqa amandla abo okokugcina. Kunconywa ukuvala usimende noma sealant, okuyinto has izinga umlilo.

Foam izindleko

Kuye umenzi kanye ethize izithasiselo, ilangabi cishe yizona ezisetshenziswa kabanzi Foam inhlangano B1 kungaba ezahlukene. Ngesikhathi umphumela intengo futhi ukudayiswa esifundeni. Ngakho, ibhaluni, lapho 750 ml ukwakheka, angathengwa ruble 350.

Foam Ukusebenzisa akufanele kwenziwe isamba ngokweqile. Okokuqala, lokho kuyoholela imfucuza impahla kanye zabasebenzi kuzoholela ukuqeda ngokweqile ngemva lukhuni. Ngemva kokuba luyanda ngosayizi. Ngakho-ke, ngaphambi kokuqala umsebenzi, kungaba kuhle ukuzama ukubeka Foam ingxenye encane.
