Mo te rongoa i te whakapiri o te 100 nga wahanga i te taumaha (pbw) i runga i:
rapa Graft-Chloroprene(te ihirangi rapa āhua 16%) | 3-5% pbw RF |
rapa Chloroprene(te ihirangi rapa āhua 20%) | 5-7% pbw RF |
Hydroxyl polyurethane(te ihirangi polyurethane āhua 15%) | 3-5% pbw RF |
Ko te tikanga, ko te nui o te whakamahinga o te kaihoko rongoa he tata ki te 3% ~ 5% o te whakapiri, engari ka piki te makuku o te hau, me paku te whakanui ake i te nui o te kaihoko whakaora. Heoi, kaua e taapiri atu i te 10%. I tenei wa, ka piki ake te pāmahana rūma, ka piki ake te tere o te tauhohenga o te kaihoko whakaora me te whakapiri. Na reira, me whakaiti te nui o te rongoa rongoa.
