Ko te piripiri e rua nga waahanga me whakamahi i roto i te waa waahanga i muri i te whakauru ki te RE. Ko te roa o te waa whaihua kaore e pa ana ki te kiko o te piripiri piripiri, engari me etahi atu waahanga e hangai ana (penei i te kapara, te antioxygen, te kirihou, te whakarewa, me era atu. Ka tata ana ki te waa e tika ana, he haora pea kotahi ra mahi ranei, piri. ka uaua ake te whakahaere, ka puea ake te puhihi. Hei whakamutunga, ka noho hei tiēre kore e taea te whakahoki. 100 whakapiripiri kounga, Hydroxyl polyurethane (Puka Polyurethane mo te 20%), RE horopeta 4-7. Rapa Chloroprene (kaute Rubber tata ki te 20%) , Ta maatau RE e mahi 4-7.

Othertahi Atu Whakaahuatanga E Pa Ana

Rokiroki:

Penapena koa ki roto i te ipu hiiri taketake i raro i te 23 ℃, ka taea te pupuri i nga hua mo nga marama 12. He tino aro ki te whakawai; ka hua mai he hauhā me te urea kore e rewa ana i te uruparenga o te wai. Mena ka uru ki te hau teh, ka marama ranei, ka tere te whakarereke o te tae, engari kaore e raru te mahi whaihua.
