ʻO ka mea ʻoluʻolu Eco o Headlamp

ʻO PP ka polypropylene, hoʻohana maʻamau i ka ʻeke meaʻai, ke ola me nā mea pili meaʻai, nā mea pāʻani a me nā wahi ʻē aʻe. Hoʻohana ʻia ia no ka shell headlamp ʻoi aku ka nui o nā mea. Ma ke ʻano o ka mālama ʻana i ke kaiapuni, ʻoi aku ka palekana o ka PP, ʻoi aku ka pollution-free a me ka recyclable. No laila ʻo ka mea PP kekahi o nā koho onā kukui waho.
Nā hiʻohiʻona o nā mea PP
1、Crystallization mea, hygroscopic liʻiliʻi, maʻalahi e hoʻoheheʻe i ka rupture, pili lōʻihi me ka metala wela maʻalahi e decompose.
2、Maikaʻi ka wai, akā nui ka nui o ka contraction a me ka waiwai contraction, maʻalahi e hana i ka lua shrinkage, dent, deformation.
3、He wikiwiki ka wikiwiki, ʻo ka ʻōnaehana ninini a me ka ʻōnaehana hoʻoluʻu pono e lohi i ka wela wela, a e hoʻolohe i ka mālama ʻana i ka mahana hoʻoheheʻe. ʻIke ʻia ke kuhikuhi o ka wela haʻahaʻa. ʻOi aku ma ka haʻahaʻa haʻahaʻa a me ke kiʻekiʻe kiʻekiʻe, ke haʻahaʻa ka mahana o ka mold ma mua o 50 degere, ʻaʻole maʻalahi nā ʻāpana plastik, maʻalahi e hana i ka welding maikaʻi ʻole, waiho i nā hōʻailona, ​​​​a me ka warping deformation ma luna o 90 deformation.

ʻO nā mea hoʻohana hou i ka hopena PP: ke kū anuanu, ke kū'ē i ka hopena maikaʻi, ka wai kiʻekiʻe, ka'ōlinolino kiʻekiʻe, ka paʻakikī maikaʻi, ke kū'ē i ka hopena; ke kumu kūikawā o ke keʻokeʻo, liʻiliʻi loa nā wahi ʻeleʻele, hiki ke pani i nā mea hou; hoʻohana nui ʻia ka mea PP no ka: injection molding, extrusion, wire drawing, etc.; ʻO nā huahana kūpono: ka pūpū uila (headlamp), ka pahu kemika, nā huahana o kēlā me kēia lā, ka pepa, ka paʻi ʻana a me nā huahana moʻo hoʻololi plastik;
2、PP kiʻi mea hana hou ʻia: ka papa injection maʻamau, ka pae kiʻekiʻe e pale aku i ke kaiapuni, ka māka kiʻi (ma luna o 250 mesh) a me ka extrusion grade hollow plate mea kūikawā; nā huahana kūpono: ka lima, ka wāwae papaʻaina, ka ʻōpala, nā mea haʻuki, ka pā, ka hīnaʻi ʻōpala, ka pūpū poʻo, a pēlā aku;
3、PP me ka fiber fireproof hoʻololi mea kūpono no nā ʻano huahana hoʻoheheʻe kiʻekiʻe;
ʻO nā hiʻohiʻona: propylene he mea ʻawaʻawa ʻole, ʻaʻala ʻole, ʻono ʻole ka waiū keʻokeʻo crystalline polymer me ka crystallization kiʻekiʻe, ka hoʻolālā maʻamau, no laila ʻoi aku ka maikaʻi o nā waiwai mechanical, ʻoi aku ka maikaʻi o kona hua, hoʻolōʻihi, ikaika hoʻoemi, paʻakikī a me ka elasticity ma mua o HDPE. ʻO kona helu hoʻoheheʻe he 164 ~ 170 degere, hiki ke hoʻopau ʻia nā huahana ma ka mahana o ʻoi aku ma mua o 100 degere, ʻoi aku ka maikaʻi o ka paʻa o ka polypropylene, ʻoi aku ka hiki ke hoʻopau ʻia e ka nitric acid concentrated, no ka mea, paʻa paʻa nā reagents kemika. Kaʻina hana: hoʻoheheʻe ʻia, hoʻoheheʻe extrusion, hollow forming, rotary forming; hoʻohana: hiki ke hoʻohana ʻia e like me ke kaʻa, uila, mechanical, mea hana, nā mea e pono ai i kēlā me kēia lā, nā kukui waho a me nā mea kūkulu hale a me nā paipu maʻamau, nā profiles, nā papa a me nā ipu liʻiliʻi like ʻole.
