Likhomaretsi / tse tlamang

Li-polyurethanes li na le mefuta e mengata hoo li ka fumanehang hape ka mokhoa oa likhomaretsi tse ka kopanyang ka mokhoa o sireletsehileng lisebelisoa tse fapaneng, joalo ka lehong, rabara, khateboto kapa khalase.

Merero ea kaho, haholo-holo, e nka monyetla ka li-glues tsa polyurethane.Baetsi ba liphutheloana le bahlahisi ba thepa ea ka ntle, bao ka bobeli ba hlokang ho tiea le matla lihlahisoa tsa bona, hangata ba itšetleha ka likhomaretsi tsa polyurethane.

Polyurethanes e na le thuso ho hlahiseng lisebelisoa tse ncha tse entsoeng ka thepa e lahliloeng le e sebelisoang hape.Mohlala, lithaere tsa koloi tse sa sebetseng hantle li ka etsoa mabala a lipapali a bana, litselana tsa lipapali kapa libaka tsa mabala a lipapali ka lebaka la makhabane a polyurethane.
