Cyanoacrylate pipili

… ua kūpaʻa kekahi mea hoʻopili cyanoacrylate ʻoihana i ka forklift 8,1-ton no hoʻokahi hola. No laila, ua hoʻonohonoho ʻia kahi moʻolelo honua hou no ka nui nui loa i hāpai ʻia e ke kāpili. I ka wā o ka hoʻopaʻa moʻolelo, ua hoʻokuʻu ʻia ke kaʻa mai kahi crane ma kahi pahu kila me ke anawaena o 7 knm wale nō. Ua hoʻopili ʻia nā ʻāpana ʻelua o ka cylinder me 3M? Weld Scotch? Paʻa koke no ka plastik a me ka ʻōpala PR100. Ua hāpai ʻia ka forklift e nā ʻenekinia Jens Schoene a me Dr. ʻO Markus Schleser o ka RWTH University Aachen a hōʻike ʻia ma ka papahana TV Kelemania Terra Xpress. Ua nānā ka luna kānāwai ma Guinness World Records i ka hoʻāʻo no hoʻokahi hola ma mua o ka hōʻoia ʻana i ka moʻolelo hou. Pono anei ka hui Kelemania e uhai i ka mooolelo mua i mea e holomua ai? ua hiki iā mākou ke ʻoi aku ma mua o 90 kg. ʻOiai ke hōʻike nei ka moʻolelo honua hou i ka hana ʻana o ka huahana ma nā wahi paʻakikī loa, ʻoi aku ka maikaʻi o nā mea hoʻopili cyanoacrylate ʻoihana i ka hana o kēlā me kēia lā a me ka hoʻohana ʻana i ka home. Ua lawa nā kulu liʻiliʻi no ka loaʻa ʻana o kahi paʻa paʻa o nā metala he nui, plastics a me ka rubber. Hoʻopaʻa kēia mau mea hoʻopili wikiwiki i nā haneli o nā hui waiwai i loko o ʻelima a ʻumi kekona, me 80% o ka ikaika piha i loaʻa i loko o hoʻokahi hola.

ʻO nā mea hoʻopili Cyanoacrylate he mea hoʻokahi, hoʻonohonoho wikiwiki i ka methyl, ethyl a me ka alkoxy adhesives. Hoʻolālā ʻia lākou e hoʻohui i nā mea like ʻole (ka ʻōpala, metala, lāʻau, ceramics, plastics a me nā mea paʻakikī e hoʻopaʻa ʻia, e like me Teflon, polyolefins). Loaʻa iā lākou nā ʻano like ʻole? mai ka wai lahilahi a hiki i ka manoanoa a i ʻole ka ʻeleʻele. Hoʻohana ʻia lākou no nā āpau liʻiliʻi loa, a hiki i ka 0,15 mm kiʻekiʻe. ʻO ka cyanoacrylate adhesives polymerize ma muli o ka hana catalytic o ka haʻahaʻa o ka lewa a ua ʻike ʻia e kahi manawa pane pōkole loa. ʻO ia ke kumu i kapa ʻia ai lākou i kekahi manawa he adhesive hoʻohana ʻia. ʻO ka pale wela o ka hapa nui o nā ʻano mai 55 ° C a + 95 ° C (me ka hoʻohui ʻana i kahi stabilizer kūpono, hiki ke loaʻa ka ikaika a hiki i + 140 ° C). Hāʻawi nā cyanoacrylate adhesives i kahi paʻa ikaika ma: kila, aluminika, plastics (e laʻa. PMMA, ABS, polystyrene, PVC , paʻakikī, a ma hope o ka hoʻohana ʻana i kahi primer kūikawā a hiki i nā plastics paʻakikī e hoʻopaʻa ʻia e like me polyethylene - PE a polypropylene - PP), elastomers (NBR, butyl, EPDM, SBR), ʻili, lāʻau. . Hiki i kēia mau mea hoʻopili ke loaʻa i ka ikaika shear? ma kahi o 7 a 20 N/mm2. ʻO ka ikaika e pili ana i ka mea e hoʻopaʻa ʻia, ke kūpono o nā ʻāpana (hui), ka mahana a me ke ʻano o ka hoʻopili. ʻO ka hemahema o kēia mau mea hoʻopili i kekahi manawa he ʻala ikaika? ʻike ʻia i ka haʻahaʻa haʻahaʻa. I kēia manawa, hoʻomohala nā mea hana i nā hanauna hou aʻe o nā adhesives e hiki ai iā ʻoe ke hoʻohui i nā mea haʻahaʻa haʻahaʻa, me nā ākea nui, nā ʻōnaehana odorless, a ʻaʻole hoʻi e hoʻoulu i ka sagging ("uhi") ma nā hui adhesive. Kūleʻa nā hui i nā aila a me nā wahie, i ka liʻiliʻi i ka makū, ʻoi aku ka nui o nā mahana kiʻekiʻe. Eia naʻe, paʻa lākou i kahi koʻikoʻi ma ka ʻoihana ma muli o ka maʻalahi o ka hoʻokō a me ka wikiwiki o ke kūkulu ʻana i ka ikaika ma nā lima? no kekahi mau ʻumi kekona.
