Pono e hoʻohana wale ʻia ka PX 5212 i loko o ka mīkini hoʻoheheʻe ʻia a hoʻolei ʻia i loko o kahi mole silicone pre-heated.ʻO ka mahalo i ka mahana o 70 ° C no ka mold he mea nui.

ʻO ka hoʻohana ʻana i ka mīkini hoʻoheheʻe ʻia:

• E wela i nā ʻāpana ʻelua ma 20 / 25 ° C inā mālama ʻia ma kahi haʻahaʻa haʻahaʻa.

• E kaupaona i ka isocyanate ma ke kīʻaha luna (mai poina e ʻae i ke koena o ke kīʻaha).

• E kaupaona i ka polyol ma ke kīʻaha lalo (ke kīʻaha hui).

• Ma hope o ka degassing no 10 mau minuke ma lalo o ka vacuum e ninini i ka isocyanate i ka polyol a hui no 4 mau minuke.

• E hoolei i loko o ka mold silicone, i wela mua ia ma 70°C.

• Hoʻokomo i loko o ka umu ma 70°C.

1 hola no 3 mm mānoanoa

E wehe i ka ʻōpala, e hoʻoluʻu i ka ʻāpana me ka ea paʻa.

Wehe i ka ʻāpana.

Pono ka lāʻau lapaʻau ma hope o ka hoʻōla ʻana no ka loaʻa ʻana o nā waiwai hope (ma hope o ka demoulding) 2h ma 70°C + 3h ma 80°C+ 2h ma 100°C

E hoʻohana i kahi mea paʻa no ka mālama ʻana i ka ʻāpana i ka wā o ka mālama ʻana ma hope

NĀ MEA: Hoʻopau nā mea hoʻomanaʻo elastic i kekahi deformation i ʻike ʻia i ka wā demoulding.

He mea nui e hoʻolei i ka PX 5212 i loko o kahi poni hou me ka hoʻolei ʻole ʻana i ka resin ma mua.

ʻO ke ola o nā ʻāpana ʻelua he 12 mahina ma kahi maloʻo a i loko o kā lākou mau pahu i wehe ʻole ʻia ma kahi mahana ma waena o 10 a 20 ° C.Hōʻalo i ka mālama ʻana no ka manawa lōʻihi ma kahi mahana ma luna o 25 ° C.

Pono e paʻa paʻa nā kīʻaha hāmama ma lalo o ka nitrogen maloʻo.

Hoʻoponopono i ka mālama ʻana

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 hoʻohana i nā mīkina lima, nā makaaniani palekana a me nā lole wai

No ka ʻike hou aku, e ʻoluʻolu e nānā i ka pepa ʻikepili palekana huahana.
