I-Cyanoacrylate adhesive

…ingcina ye-cyanoacrylate yezimboni imelane neforklift engamathani angu-8,1 ihora. Ngakho, kwaqoshwa umlando omusha wezwe wenani elikhulu kunawo wonke elaphakanyiswa ingcina. Ngesikhathi sokuhlelwa kwerekhodi, imoto yamiswa ku-crane ku-cylinder yensimbi enobubanzi obungamasentimitha angu-7 kuphela. Izingxenye ezimbili ze-cylinder zazihlanganiswe ne-3M? I-Scotch Weld? I-adhesive esheshayo yepulasitiki nerabha PR100. I-forklift yaphakanyiswa ngonjiniyela uJens Schoene noDkt. U-Markus Schleser we-RWTH University Aachen futhi wavela ohlelweni lwe-TV lwaseJalimane i-Terra Xpress. Ijaji ebelikhona kwaGuinness World Records libuke ukuhlolwa ihora lonke ngaphambi kokuqinisekisa ngokusemthethweni irekhodi elisha. Ingabe iqembu laseJalimane lalidinga ukwephula irekhodi langaphambili ukuze liphumelele? sikwazile ukumedlula ngo-90 kg. Nakuba irekhodi lomhlaba omusha libonisa ukusebenza komkhiqizo okumangalisayo ezindaweni ezinokhahlo ngokwedlulele, izinto zokunamathisela ze-cyanoacrylate zezimboni zisebenza ngokulinganayo kukho kokubili ukukhiqizwa kwansuku zonke nasekusetshenzisweni kwasekhaya. Amaconsi ambalwa anele ukuze uthole isibopho esiqinile sezinsimbi eziningi, amapulasitiki kanye nenjoloba. Lezi zinamathiselo ezisebenza ngokushesha zibophezela amakhulukhulu enhlanganisela yezinto kumasekhondi amahlanu kuya kweyishumi, ngo-80% wamandla aphelele afinyelelwe phakathi nehora.

Izinamatheliso ze-Cyanoacrylate ziyingxenye eyodwa yokunamathelisa ukushesha okusekelwe ku-methyl, ethyl ne-alkoxy. Zenzelwe ukuxhumanisa amapheya ahlukahlukene wezinto (irabha, insimbi, izinkuni, izitsha zobumba, ipulasitiki nezinto okunzima ukuzinamathelisa, njengeTeflon, i-pololefins). Ingabe banokuvumelana okuhlukile? kusuka oketshezini oluncane kuya emiqulwini ewugqinsi noma efana nejeli. Zisetshenziselwa izikhala ezincane kakhulu, kuze kufike ku-0,15 mm. I-Cyanoacrylate adhesives i-polymerize ngenxa yesenzo se-catalytic somswakama womoya futhi ibonakala ngesikhathi esifushane kakhulu sokuphendula. Yingakho ngezinye izikhathi zibizwa ngokuthi ama-post-consumer adhesives. Ukumelana nokushisa kwezinhlobo eziningi kusuka ku-55 ° C kuya ku-95 ° C (ngokwengezwa kwe-stabilizer efanelekile, amandla afinyelela ku-+140 ° C angafinyelelwa). I-PMMA, i-ABS, i-polystyrene, i-PVC , kanzima, futhi ngemva kokusebenzisa i-primer ekhethekile, ngisho namaplastiki aqinile-ukunamathela njenge-polyethylene - PE ne-polypropylene - PP), ama-elastomers (NBR, butyl, EPDM, SBR), isikhumba, izinkuni. Ingabe lezi zinto ezinamathelayo zithola amandla okugunda? cishe 7 kuya ku-20 N/mm2. Amandla ancike ezintweni ezinamathiselwe, ukulingana kwezingxenye (okuhlangene), izinga lokushisa kanye nohlobo lweglue. Ububi balezi zinto zokunamathisela ukuthi ngezinye izikhathi zinephunga elinamandla? kubonakala ikakhulukazi kumswakama womoya ophansi. Njengamanje, abakhiqizi bathuthukisa izizukulwane eziningi ezintsha zokunamathisela ezenza kube lula ukuxhuma izinto ezibamba ngokuqinile ezinezikhala ezinkulu, izinhlelo ezingenaphunga, kanye nalezo ezingabangeli ukugoqa (“umusi”) emalungeni okunamathela. Ama-compounds amelana namafutha namafutha, futhi kancane kancane kumswakama, ikakhulukazi emazingeni okushisa aphakeme. Kodwa-ke, banendawo ebalulekile embonini ngenxa yokulula kwabo ukubulawa kanye nokuthuthukiswa okusheshayo kwamandla engalo? emizuzwaneni embalwa, emashumini ambalwa.
