Nga Tikanga Tukatuka Maamaa
• Whakawerahia nga wahanga e rua (isocyanate me te polyol) ki te 23°C mena ka rokiroki i te iti o te pāmahana.
• He mea nui : Kia kaha te ruru i te wahanga A i mua i ia paunatanga.
• Paunatia nga wahanga e rua.
• I muri i te whakaheke mo te 10 meneti i raro i te ranunga korehau mo te
1 meneti me te PX 245
2 meneti me te PX 245/L
• Maka i raro i te korehau ki roto i te pokepokea silicone, i whakamahana i mua i te 70°C.
• Whakakorehia i muri i te 30 meneti te iti rawa i te 70°C (whakaaetia kia whakamatao te wahanga i mua i te whakakorenga).
Te Whakahaere Whakatupato
Ko nga tikanga mo te hauora me te haumaru me mau ki te whakahaere i enei hua:
• whakarite kia pai te hau
• mau karapu me nga karaehe haumaru
