Zabwino ndi kusamala kwa thovu la polurethane.

Ubwino wa Bowamba Wambout

1.Chikuthandizeni pakupulumutsa mphamvu, palibe mipata mukadzaza, komanso kuphatika kwamphamvu mutachiritsa.

2.Imachita zowawa ndi kugwedezeka, ndipo sichinganyengedwe, contor, kapena kugwa mutachiritsa.

3.Ndipo ma dright otsika kutentha kwa mafuta, kuthana ndi nyengo komanso kuteteza kutentha.

4. Kuchulukitsa kwambiri, kusokonekera, kusokonekera kwa mawu, chinyezi komanso chinyezi - umboni wonyowa mutachiritsa.

Kodi tiyenera kusamala chiyani pakumanga?

Kutentha kwachibadwa kwa chithotho cha polyirethane ndiye kuti + 5 ~ + 40 ℃, ndipo kutentha kwabwino kwambiri ndi + 18 ~. Pankhani ya kutentha kochepa, tikulimbikitsidwa kuyika kutentha kosalekeza kwa +25 kupita ku + 30 ° C kwa mphindi 30 musanagwiritse ntchito kutsimikizira bwino. Kutsutsana ndi kutentha kwa chithovuchi ndi -35 ℃ ℃ ~ + 80 ℃.

Chithovu cha polurethane ndi chithovu chonyowa ndipo chizithiridwa pamalo onyowa mukamagwiritsidwa ntchito. Chinyezi chapamwamba, chokomera mwachangu. Chithovu chosachiritsika chimatha kutsukidwa ndi othandizira kuyeretsa, pomwe chiwaya chochiritsidwa chimachotsedwa ndi makina (saning kapena kudula). Chiuno chochiritsidwa chidzasanduka chikasu mukawonekera ku kuwala kwa ultraviolet. Ndikulimbikitsidwa kusonkhanitsa chithovuchi ndi zida zina (matope a simenti, utoto, etc.). Mukatha kugwiritsa ntchito spray mfuti, chonde yeretsani ndi woyeretsa wapadera nthawi yomweyo. Mukasinthanitsa tank, gwedezani tank yatsopano (osachepera 20), chotsani thanki yopanda kanthu, ndipo m'malo mwatsopano tanki yatsopano kuti chipinda chizichirikiza.

Valavu yoyendetsera yoyendetsa ndikuyambitsa mfuti yopukutira kuchuluka kwa chithovu. Tsekani valavu yoyenda mumayendedwe otsekemera pomwe kupopera mbewu mankhwalawa.
