Nā mea e pono ai ka nānā ʻana o PPSU i ke kaʻina hana o ka hoʻoheheʻe ʻana

ʻO PPSU, ka inoa ʻepekema o ka polyphenylene sulfone resin, he thermoplastic amorphous me ka ʻike kiʻekiʻe a me ke kūpaʻa hydrolytic, a hiki i nā huahana ke kū i ka disinfection mau.

ʻOi aku ka maʻamau o ka PPSU ma mua o polysulfone (PSU), polyethersulfone (PES) a me polyetherimide (PEI).

ʻO ka noi o PPSU

1. Nā mea hana hale a me nā meaʻai: hiki ke hoʻohanaʻia no ka hanaʻana i nā mea hana umu microwave, nā mea hoʻomehana kofe, nā humidifiers, nā lauoho lauoho, nā meaʻai, nā'ōmole pēpē, a pēlā aku.

2. Nā huahana kikohoʻe: ma kahi o ke keleawe, zinc, aluminika a me nā mea metala ʻē aʻe, ka hana ʻana i nā pahu kiaʻi, nā mea hoʻonaninani kūloko a me nā kope kope, nā ʻāpana kamera a me nā ʻāpana kikoʻī ʻē aʻe.

3. ʻOihana Mechanical: hoʻohana nui i nā kikoʻī i hoʻoikaika ʻia i ke aniani fiber, loaʻa nā huahana i nā ʻano o ke kū'ē ʻana, ka paʻakikī, ke kūpaʻa dimensional, a me nā mea ʻē aʻe, kūpono no ka hana ʻana i nā brackets a me nā ʻāpana mechanical shell a pēlā aku.

4. Ke kahua lapaʻau a me ke olakino: kūpono loa i nā mea hana niho a me nā mea ʻokiʻoki, nā pahu disinfection (palapala) a me nā ʻano mea hana lāʻau implantable ʻaʻole kanaka.

ʻO ka hiʻohiʻona PPSU

ʻO nā ʻāpana semi-transparent melemele maoli a i ʻole nā ​​​​particle opaque.

Nā koi hana kino o PPSU

Pono e noʻonoʻo ʻia kekahi mau helu i ka wā e hoʻolālā ai i nā huahana PPSU a me nā mold

1. He ilihune ka fluidity o PSU hehee, a me ka lakio o ka hehee kahe ana ka lōʻihi i ka paia mānoanoa mea wale nō e pili ana i 80. No laila, ka paia mānoanoa o PSU huahana e ole emi ma mua o 1.5mm, a me ka hapa nui o lakou ma luna o 2mm.

Pili nā huahana PSU i nā notches, no laila e hoʻohana ʻia ka hoʻololi arc ma nā kihi ʻākau a i ʻole.ʻO ka hoʻoheheʻe ʻana o ka PSU ka mea paʻa, ʻo ia ka 0.4% -0.8%, a ʻo ka hoʻoheheʻe ʻana o ka kahe ʻana he mea like ia me ka mea ma ke ala kū.ʻO ka huina demoulding he 50:1.No ka loaʻa ʻana o nā huahana ʻālohilohi a maʻemaʻe, ʻoi aku ka nui o ka roughness o ka ʻili o ka lua ma mua o Ra0.4.I mea e maʻalahi ai ka hoʻoheheʻe ʻana, pono ka sprue o ka mold e pōkole a mānoanoa, ʻo kona anawaena he 1 / 2 ka nui o ka mānoanoa o ka huahana, a he 3 ° ~ 5 °.ʻO ka ʻāpana keʻa o ke kahawai shunt he arc a trapezoid paha e pale aku i ka noho ʻana o nā piko.

2. Hiki ke hoʻoholo i ke ʻano o ka puka e ka huahana.Akā ʻo ka nui e like me ka nui, ʻo ka ʻāpana pololei o ka ʻīpuka e like me ka pōkole, a hiki ke mālama ʻia kona lōʻihi ma waena o 0.5 ~ 1.0mm.Pono ke kūlana o ke awa hānai ma ka pā mānoanoa.

3. E hoʻonoho i nā puka anuanu ma ka hope o ka sprue.No ka mea, ʻo nā huahana PSU, ʻoi aku ka ʻoi aku o nā huahana ʻeleʻele, pono ke kiʻekiʻe o ke kaomi ʻana a me ka wikiwiki o ka hoʻokele ʻana, pono e hoʻonohonoho ʻia nā lua hoʻopau maikaʻi a i ʻole nā ​​​​grooves i mea e hoʻopau ai i ka ea i loko o ka mold i ka manawa.Pono e mālama ʻia ka hohonu o kēia mau puka makani ma lalo o 0.08mm.

4. Pono ka hoʻonohonoho ʻana o ka mahana wela e hoʻomaikaʻi i ka wai o PSU heheʻe i ka wā hoʻopiha kiʻiʻoniʻoni.Hiki ke kiʻekiʻe ka mahana o ka mold e like me 140 ℃ (ma ka liʻiliʻi 120 ℃).
