ʻO ka wehewehe pōkole:

ʻO ka hoʻolei ʻana no ka hana ʻana i nā ʻāpana prototype a me nā mea hoʻohenehene i loaʻa nā waiwai mechanical e like me PP a me HDPE, e like me ka panel panel, bumper, pahu lako, uhi a me nā mea hana anti-vibration.

• 3-ʻāpana polyurethane no ka hoʻolei ʻana i ka ʻūhā

• ka elongation kiʻekiʻe

• ka hana maʻalahi

• Hiki ke hoʻololi i ka modulus Flexural

• Ke kū'ē i ka hopena kiʻekiʻe,ʻaʻohe haki

• Maikaʻi ka maʻalahi

E hoʻouna i ka leka uila iā mākou Hoʻoiho i ka Pepa ʻIkepili

• E hoʻomaʻamaʻa mua i ka isocyanate i 23 - 30°C inā mālama ʻia ma lalo o 20°C.

• E hoʻomaʻamaʻa mua i ka polyol a me ka hapa C i 40 ° C ma mua o ka hoʻohana ʻana.Pono e hoʻoulu i ka polyol a hiki i ka like ʻole o ka kala a me ke ʻano.

• E kaupaona i nā ʻāpana e like me ka ratio hui ʻana, e hoʻokomo i ka isocyanate i loko o ke kīʻaha luna, e hoʻohui i ka ʻāpana C i ka polyol i ka premix.

• E ninini i ka isocyanate i loko o ka polyol (loa'a ka Māhele C) a hui no 1 - 2 mau minuke ma hope o ka ho'ohehe'e 'ia no 10 mau minuke kaawale.

• E hoolei ma lalo o ka mimi i loko o ka silicone mold preheated i 70°C.

• Demould ma hope o 60 - 90 minuke ma 70°C (ʻO ka nui o ka Māhele C i hoʻohana ʻia, ʻoi aku ka lōʻihi o ka manawa demoulding e pono ai).

Pono e mālama ʻia nā mālama olakino maʻamau i ka wā e lawelawe ai i kēia mau huahana:

E hōʻoia i ka ea maikaʻi

E komo i nā mīkina lima, nā makaaniani palekana a me nā lole pale.
