ʻO ka noiʻi o ka ultrasonic plastic welding lako hana-I

I ke kaʻina hana o nā huahana plastik, hiki i ka ʻenehana welding ultrasonic ke hoʻopaʻa i nā huahana plastik me ka wikiwiki.Ma waho aʻe, i ke kaʻina hana o ka sila, ʻaʻole pono ka hoʻomehana ʻana i nā huahana plastik waho a i ʻole ka pono o ka flux, maikaʻi loa ka hopena welding a kiʻekiʻe loa ka ikaika welding.I ka wā o ka ʻenehana welding ultrasonic i ke kaʻina noi, ʻo nā hiʻohiʻona o ke kumukūʻai haʻahaʻa a me ka palekana kiʻekiʻe e hoʻohana nui ʻia i nā huahana mīkini palaki, ʻoihana mea kākau, ʻoihana makeup, ʻoihana pāʻani, ʻoihana uila.

1. Ultrasonic plastic welding technology a me kona mau ano

1. 1 Ultrasonic plastik kuʻihao 'enehana

ʻO ka ʻenehana hoʻoheheʻe ʻana i ka ultrasonic ka mea e wili pū ai i nā huahana plastik ma o ke kumu kani ultrasonic vibration.Ke hoʻohana ʻia ka hawewe kani ultrasonic e weld i nā welds plastik, e kū mai ka friction ma waena o nā molekala i loko o ka hawewe kani ultrasonic a me ka ʻili pili o nā huahana plastik, a laila hiki koke ka mahana o ka kuʻihao ma ka ʻili hoʻoheheʻe plastik i ka helu heheʻe o ka. palaki.I kēia manawa, e kahe pū ana ka heheʻe o nā welds plastik ʻelua.I ka wā e pau ai ka haʻalulu ʻana o nā molekala i ka hawewe kani ultrasonic, hoʻoheheʻe ʻia ka plastic melt i ke kaomi a hoʻopaʻa koke ʻia a crystallizes, e hoʻohālikelike ai i ka weld.ʻO ka ikaika o ka lae hoʻoheheʻe e kokoke ana i ka mea maka.I mea e weld ai i ka plastic mechanical welds, pono ia e hōʻoia i ka wela i hana ʻia e ka hawewe kani ultrasonic hiki ke hana wale i loko o ka welding wahi, a pono e hoʻohana ʻia ke ʻano alakaʻi ikehu e hoʻololi a alakaʻi i ka wela i hana ʻia e ka hawewe kani ultrasonic, a ua kapa ʻia ka ʻōnaehana alakaʻi ikehu ka ʻōnaehana uwea kuʻi.

1.2 Nā hiʻohiʻona o ka ʻenehana hoʻoheheʻe ultrasonic plastic

He kūpono wale nō ka ʻenehana hoʻoheheʻe ʻana i ka ultrasonic no nā thermoplastics, a no nā mea ʻē aʻe ʻaʻole kūpono no ka hoʻohana.ʻO ke kumu o ke koho ʻana i nā thermoplastics ʻo ia ka hoʻololi ʻole ʻana o nā waiwai kemika a me ke kino o nā thermoplastics i ka wā e hoʻoheheʻe ʻia ai a hoʻōla ʻia.Hiki ke hoʻokaʻawale ʻia nā Thermoplastics i crystalline a me amorphous e like me kā lākou mau waiwai.Ma waena o lākou, ʻike ʻia ka helu heheʻe o ka plastic crystalline, a e hoʻonohonoho ʻia kona mau molekele kūloko e like me nā lula pili i ka wā e hoʻōla ai e hana i ka ʻāpana aniani.
