Izinzuzo kanye nezinyathelo zokuphepha ze-polyurethane foam.

Izinzuzo ze-Polyurethane Foam Caulking

1. Ukusebenza kahle okuphezulu nokonga amandla, akukho zikhala ngemuva kokugcwalisa, kanye nokubopha okuqinile ngemuva kokupholisa.

2. Ayikwazi ukushaqeka futhi iyacindezela, futhi ngeke iqhekeke, igqwale, noma iwe ngemva kokupholisa.

3.Ngokuba nokushisa okuphansi kakhulu, ukumelana nesimo sezulu kanye nokulondolozwa kokushisa.

4. Ukuvikela okusebenzayo kakhulu, ukuvikela umsindo, ukungangeni manzi futhi okuvikela umswakama ngemva kokwelashwa.

Yini okufanele inakwe ngesikhathi sokwakha?

Izinga lokushisa elijwayelekile lokusetshenziswa kwe-polyurethane foam lingu-+5~+40℃, kanti izinga lokushisa elingcono kakhulu lokusetshenziswa lingu-+18~+25℃. Uma izinga lokushisa liphansi, kunconywa ukuthi ulibeke ezingeni lokushisa elingaguquki elingu-+25 kuya ku-+30 °C imizuzu engama-30 ngaphambi kokusebenzisa ukuqinisekisa ukusebenza kwalo okuhle kakhulu. Izinga lokumelana nokushisa kwe-polyurethane foam elilungisiwe lingu--35℃～+80℃.

I-foam ye-polyurethane iyi-foam eqeda umswakama futhi kufanele ifuthwe ezindaweni ezimanzi uma isetshenziswa. Uma umswakama uphakeme, kulapho ukupholisa kushesha khona. I-foam engakaqedwa ingahlanzwa ngezinto zokuhlanza, kuyilapho i-foam eqediwe isuswa ngezindlela zomshini (ukusikwa noma ukusika). I-foam eqediwe izophenduka ibe phuzi uma ivezwa ekukhanyeni kwe-ultraviolet. Kunconywa ukumboza ubuso be-foam eqediwe ngezinye izinto (usimende, upende, njll.). Ngemva kokusebenzisa isibhamu sokufafaza, sicela usihlanze nge-ejenti yokuhlanza ekhethekile ngokushesha. Uma ushintsha ithangi lezinto, shukumisa ithangi elisha kahle (okungenani izikhathi ezingu-20), susa ithangi elingenalutho, bese ushintsha ngokushesha ithangi lezinto ezintsha ukuze uvimbele ukuxhumana kwesibhamu ekuqineni.

Ivalvu yokulawula ukugeleza kanye nesiqalisi sesibhamu sokufafaza kulawula inani lokugeleza kwegwebu. Vala ivalvu yokugeleza ngendlela yewashi lapho ukufutha kuyeka.
