Cyanoacrylate nplaum nplaum
... muaj cyanoacrylate nplaum tiv thaiv 8,1-tuj forklift rau ib teev. Yog li, lub ntiaj teb cov ntaub ntawv tshiab tau teeb tsa rau qhov loj tshaj plaws nqa los ntawm cov kua nplaum. Thaum lub sijhawm teeb tsa, lub tsheb tau raug tshem tawm ntawm lub crane ntawm lub tog raj kheej steel nrog txoj kab uas hla ntawm tsuas yog 7 cm. Ob qhov ntawm lub tog raj kheej tau txuas nrog 3M? Scotch Weld? Instant nplaum rau yas thiab roj hmab PR100. Lub forklift tau nqa los ntawm engineers Jens Schoene thiab Dr. Markus Schleser ntawm RWTH University Aachen thiab nthuav tawm hauv German TV program Terra Xpress. Tus kws txiav txim plaub ntug ntawm Guinness World Records tau saib qhov kev xeem rau ib teev ua ntej lees paub cov ntaub ntawv tshiab. Pab neeg German puas yuav tsum tau rhuav tshem cov ntaub ntawv dhau los kom ua tiav? Peb tswj kom dhau nws ntau li 90 kg. Thaum lub ntiaj teb cov ntaub ntawv tshiab qhia tau hais tias kev ua tau zoo ntawm cov khoom lag luam hauv ib puag ncig hnyav heev, cov cyanoacrylate adhesives muaj qhov sib npaug zoo hauv kev ua haujlwm txhua hnub thiab siv hauv tsev. Ob peb tee yog txaus kom tau txais kev ruaj khov ntawm ntau cov hlau, yas thiab roj hmab. Cov nplaum nplaum nplaum nplaum no ua rau ntau pua ntawm cov khoom sib txuas hauv tsib mus rau kaum vib nas this, nrog 80% ntawm tag nrho lub zog ua tiav hauv ib teev. Cov yees duab no tau pom thawj zaug ntawm https://www.youtube.com/watch?v=oWmydudM41c
Cyanoacrylate adhesives yog ib qho khoom siv, ceev ceev methyl, ethyl thiab alkoxy raws li cov nplaum. Lawv tau tsim los txuas cov khoom sib txawv (rubber, hlau, ntoo, ceramics, plastics thiab cov ntaub ntawv uas nyuaj rau kev sib txuas, xws li Teflon, polyolefins). Lawv puas muaj textures sib txawv? los ntawm cov kua nyias mus rau tuab los yog jelly zoo li pawg. Lawv siv rau qhov sib txawv me me, txog li 0,15 hli. Cyanoacrylate adhesives polymerizes vim catalytic ua ntawm atmospheric av av thiab yog yus muaj los ntawm lub sij hawm luv luv heev. Tias yog vim li cas lawv qee zaum hu ua adhesives siv. Qhov kub tsis kam ntawm ntau hom yog los ntawm 55 ° C mus rau + 95 ° C (nrog rau qhov sib ntxiv ntawm qhov tsim nyog stabilizer, muaj zog txog +140 ° C tuaj yeem tau txais). (xws li PMMA, ABS, polystyrene, PVC, tawv, thiab tom qab siv cov primer tshwj xeeb txawm tias nyuaj-rau-bond yas xws li polyethylene - PE thiab polypropylene - PP), elastomers (NBR, butyl, EPDM, SBR), tawv, ntoo . Cov nplaum no puas muaj zog shear? 7-20 N / mm2. Lub zog yog nyob ntawm cov khoom sib txuas, qhov haum ntawm qhov chaw (sib koom), qhov kub thiab txias thiab hom nplaum. Qhov tsis zoo ntawm cov nplaum no yog qee zaum muaj ntxhiab tsw? tshwj xeeb tshaj yog pom ntawm cov av qis. Tam sim no, cov tuam ntxhab tab tom tsim ntau tiam tshiab ntawm cov nplaum nplaum uas tso cai rau koj los txuas cov ntsiab lus qis, nrog cov khoob loj, tsis muaj ntxhiab tsw, thiab tseem tsis ua rau sagging ("pa") ntawm cov nplaum nplaum. Cov pob qij txha tiv taus cov roj thiab cov roj, kom tsawg dua rau cov dej noo, tshwj xeeb tshaj yog thaum kub siab. Txawm li cas los xij, lawv puas tuav ib qho chaw tseem ceeb hauv kev lag luam vim qhov yooj yim ntawm kev tua thiab kev ceev ntawm kev tsim lub zog ntawm tes? rau ob peb, ob peb kaum vib nas this.
