Raina hanga pepa kowakawaka
Taupū whakapiri
Ko te pokey me te kiko totoka o te whakapiri mo te papa kowakawaka me whakatika kia rite ki te wa. I te nuinga o te wa, i te iti o te pāmahana me te iti o te haumākū (te hotoke), ko te viscosity o te whakapiri mo te kaata kotahi-kowakawaka he 17-21s (te paninga e 4 nga kapu, he rite ki raro), me te ihirangi totoka ko 17% -19%; ko te pokey o te whakapiri mo te kaata e toru-kowakawaka he 40- 60s, ko te kiko totoka he 18% ki te 20%. I roto i te pāmahana teitei me te haumākū tiketike (raumati), ko te viscosity o te whakapiri mo te kaata kowakawaka kotahi he 20-25s, me te ihirangi totoka ko 19% -22%; ko te 55-90s te viscosity o te whakapiri mo te kaata e toru-kowakawaka, me te 21%-25% te kiko totoka. %. I tua atu, me whakarite kia 15-20mm te roa o te piri (toua he piri ki runga i te koromatua, herea ki te maihao tohu, kia ata toia nga maihao e rua ki te tawhiti i waenga i nga maihao e rua ina pakaru te whakapiri) he 15-20mm.
