ʻOi aku ka maikaʻi loa o ka hoʻolei ʻana i ka wai ʻawaʻawa PMMA

ʻOi aku ka maikaʻi loa o ka hoʻolei ʻana i nā mea hoʻoheheʻe ʻana i ke kiʻi PMMA

ʻO ka wehewehe pōkole:

Hoʻohana ʻia e ka hoʻolei ʻana i nā ʻāpana silicone no ka hana ʻana i nā ʻāpana prototype a hiki i ka mānoanoa 10 mm: nā kukui, nā aniani, nā ʻāpana like ʻole me PMMA, cristal PS, MABS…

• ʻO ka māliko kiʻekiʻe

• ka poli maalahi

• Kiʻekiʻe reproduction pololei

• Ke kū'ē UV maikaʻi

• ka hana maʻalahi

• Hoʻopau wikiwiki

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

• E hoʻohana i loko o ka mīkini hoʻoheheʻe ʻia.

• E hoʻomāhana i ka mold ma 70°C (ʻoi aku ka maikaʻi o ka polyaddition silicon mold).

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

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

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

• Ma hope o ka degasing no 10 mau minuke ma lalo o ka momi e ninini i ka ʻāpana A i ka ʻāpana B a hui ʻia no 1 minuke 30 a 2 mau minuke.

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

• E hoʻokomo i loko o ka umu ma 70 ° C ka liʻiliʻi.

• E hoʻopau ma hope o 45 mau minuke ma 70°C.

• E hana i ka hana wela penei: 3 hola ma 70°C + 2 hola ma 80°C a me 2 hola ma 100°C.

• I ka wā e ho'ōla ai, e kau i ka ʻāpana ma ke kū.

Hoʻoponopono i ka mālama ʻana

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