He aha ka Polyphenylene Sulphide (PPS)
ʻO ka PPS no ka Polyphenylene Sulphide kahi thermoplastic ʻenehana kiʻekiʻe i ʻike ʻia e kāna hui ʻana o nā waiwai.
He polymer semi-crystalline, opaque a paʻa i loaʻa kahi helu hoʻoheheʻe kiʻekiʻe loa (280°C) a loaʻa i nā ʻāpana para-phenylene e hoʻololi me ko lākou mau loulou sulphide.
Loaʻa i ka PPS kahi koena maikaʻi loa o nā waiwai e like me ke kūpaʻa ʻana o ke ahi, ke kūpaʻa kemika maikaʻi, ke kūpaʻa wela kiʻekiʻe, nā mana dimensional, ka ikaika mechanical a me ka insulation uila.
Hiki ke hana maʻalahi ka PPS no ka mea e piʻi ana kona paʻakikī me nā wela kiʻekiʻe.
ʻO kēia mau hiʻohiʻona maikaʻi loa ka PPS i kahi koho maikaʻi loa i nā thermosets a me nā metala no ka hoʻohana ʻana i nā noi a me nā mea hana, nā ʻāpana kaʻa a me nā uila.
Nui nā mea kūʻai aku i nā ʻāpana hoʻoheheʻe PPS i ke ʻano o ka noʻonoʻo inertia: ʻaʻohe mahana wela, ʻaʻole nui ka puka, lawa ʻole ka pau, ka manawa hoʻomaha pōkole.
Hiki i ka mahana o ka mold ke hana i ka ili o ka huahana wikiwiki crystallization, laumania me ka lana ʻole o ka fiber kahe, ʻo ka mea nui e hoʻoikaika nui i ka ikaika o ka huahana;ʻO ka nui o ka puka pā e pili ana i ka nui o ka injection plastic, a aia nā koi no ka hoʻonohonoho ʻana i ke kaomi a me ka nui o ka injection.E loaʻa nō hoʻi kahi hopena i ka nalo puʻe distal o nā huahana multi-point.
ʻAʻole lawa ka hoʻopau ʻana e hōʻiliʻili wikiwiki i ke kinoea, ka hopena i ke ahi a me ke ʻano ma ka ʻili a me ka huelo o ka huahana.
ʻO ka PPS ponoʻī e loaʻa i ka sulfide a me nā mea liʻiliʻi o ka polyphenylbiphenyl polymer precipitation, no laila he mea nui ka hoʻolālā ʻana o ka exhaust!
ʻO ka manawa hoʻomaha pōkole, ʻaʻole kūpono i ka crystallization piha o ka huahana!
I mea e ʻimi ai i ka mana hana, nui nā mea kūʻai aku e hoʻemi pololei i ka pōʻaiapili hana i ka nui, e hopena i ka pōkole crystallization cycle, ʻaʻole kūpono i ka hopena o ka hanana i ka mea mua!
Ke koho kūpono o nā mea, hana ʻepekema!
E hāʻawi i ke kākoʻo hoʻokahi mai nā mea maka, nā ʻōpala, nā kaʻina hana, nā huahana i hoʻopau ʻia, nā hoʻopiʻi o nā mea kūʻai aku a me nā kaulahao piha ʻē aʻe!
Nā mea hana kiʻekiʻe a puni ʻoe e nā loea hoʻonā hoʻokahi!
