Ubwino ndi kusamala kwa thovu la polyurethane.

Ubwino wa Polyurethane Foam Caulking

1.Kuchita bwino kwambiri komanso kupulumutsa mphamvu, palibe mipata mutatha kudzaza, ndi kugwirizana kolimba pambuyo pochiritsa.

2.Iyo ndi shockproof ndi compressive, ndipo sidzasweka, corrode, kapena kugwa pambuyo kuchiza.

3.Ndi ultra-low kutentha matenthedwe conductivity, kukana nyengo ndi kusunga kutentha.

4. Kutsekemera kwapamwamba kwambiri, kutsekemera kwa mawu, kutsekemera madzi ndi chinyezi pambuyo pochiritsa.

Kodi tiyenera kulabadira chiyani pomanga?

Kutentha kwabwino kwa polyurethane thovu ndi +5 ~ + 40 ℃, ndipo kutentha kwabwino kwambiri ndi +18 ~ +25 ℃. Pakakhala kutentha kochepa, tikulimbikitsidwa kuyiyika pa kutentha kosalekeza kwa +25 mpaka +30 ° C kwa mphindi 30 musanagwiritse ntchito kuti muwonetsetse kuti ikugwira bwino ntchito. Kutentha kosiyanasiyana kwa thovu lochiritsidwa ndi -35 ℃～+80 ℃.

Foam polyurethane ndi thovu lochotsa chinyezi ndipo liyenera kupopera pamalo onyowa likagwiritsidwa ntchito. Kuchuluka kwa chinyezi, m'pamenenso machiritso amafulumira. Chithovu chosachiritsika chingathe kutsukidwa ndi zoyeretsa, pamene chithovu chochiritsidwa chimachotsedwa ndi njira zamakina (sanding kapena kudula). Chithovu chochiritsidwa chimakhala chachikasu chikawonetsedwa ndi kuwala kwa ultraviolet. Ndibwino kuti muvale pamwamba pa chithovu chochiritsidwa ndi zipangizo zina (matope a simenti, utoto, etc.). Mukatha kugwiritsa ntchito mfuti yopopera, chonde iyeretseni ndi woyeretsa wapadera nthawi yomweyo. Mukasintha thanki yazinthu, gwedezani bwino thanki yatsopano (nthawi zosachepera 20), chotsani thanki yopanda kanthu, ndipo mwachangu m'malo mwa thanki yatsopanoyo kuti mfuti isachiritsidwe.

Valve yowongolera kuthamanga ndi choyambitsa chamfuti chopopera amawongolera kuchuluka kwa kutuluka kwa thovu. Tsekani valavu yoyenda molunjika pamene kupopera mbewu kumasiya.
