Momwe mungasungire mbale ya sieve ya polyurethane

Chophimba cha polyurethane ndi chotchingira chosawonongeka chophwanyira ndi kuphimba miyala yachitsulo, kugawa malasha osaphika, golide, zipangizo zomangira, ndi kuphimba mchenga ndi miyala yamtengo wapatali pa ntchito zamagetsi ndi mphamvu za nyukiliya. Tamvetsetsa kale mafakitale enieni omwe zotchingira za polyurethane zimagwiritsidwa ntchito, koma sitingadziwe zomwe tiyenera kusamala nazo posunga zotchingira za polyurethane, choncho tiyeni tiwone momwe zotchingira za polyurethane ziyenera kusungidwira pamodzi!

Kusungiramo zipangizo zomangira ndi zitsulo za mbale za sieve ya polyurethane kuyenera kuyikidwa motsatira mitundu yosiyanasiyana ya zitsulo, manambala a uvuni, mitundu ndi zofunikira, kutalika ndi zizindikiro zosiyanasiyana zaukadaulo. Zipangizo zobwezedwa ziyeneranso kuyikidwamo m'zida zosiyanasiyana kuti zigwiritsidwe ntchito mosavuta. Chitsulocho chiyenera kukhala cholimba, cholimba ndi asidi komanso cholimba ndi dzimbiri. Chitsulo chozimiririka chiyenera kuyikidwamo padera, kuchotsedwa dzimbiri pakapita nthawi, ndikugwiritsidwa ntchito mwachangu momwe zingathere. Kusungiramo zipangizo zomangira za sikirini za polyurethane, ndi kusungiramo mchenga ndi miyala, ziyenera kuyikidwamo m'mizere ndikusungidwa pamalo ogwiritsira ntchito pulojekitiyi kapena pafupi ndi malo osakanizira malinga ndi dongosolo lomangira, ndipo chiwerengero cha zofunikira chiyenera kufotokozedwa pa mbale yoyikamo m'mizere. Nthaka iyenera kukhala yosalala komanso yolimba, ndipo mchenga ndi miyala ziyenera kuyikidwa pamwamba pa sikweya kuti madzi otayira ndi utomoni wamadzi asalowe mu mulu wa miyala. Miyala yamitundu kapena miyala yoyera nthawi zambiri imatumizidwa m'matumba oluka. Ngati yayikidwamo m'matumba ambiri, iyenera kugwiritsidwa ntchito mutatsuka.
