3M yog ntxiv cov khoom siv pob zeb Phom ntub cov khoom siv hluav taws xob (polyurethane adhesives) DP6310NS thiab DP6330NS rau nws cov khoom siv tawv nplaum. Cov khoom no yog tsim los rau cov khoom siv hauv lub tsheb, cov tsheb npav, RVs, cov tsheb tshwj xeeb thiab cov neeg caij npav, thiab lwm yam kev lag luam xws li cov khoom ua si thiab cov khoom.
Tsim muaj ntau thiab ntau tus engineers cia siab rau cov ntaub ntawv sib txuas lus kom txo tau cov nqi thiab nce rau qhov sib txawv hauv kev sibtham. Cov kws kho dua tshiab tsis zoo rau cov ntaub ntawv no vim tias nkees nkees txwv kev quav dej quav cawv thiab, feem ntau, engineers yuav tsum fij kom haum raws li cov kev txwv ntawm cov neeg kho tshuab.
Cov khoom sib dhos polyurethane ntau pob zeb muaj cov khoom siv hluav taws xob ua ke uas tsim los ua cov khoom siv rau lub nruab nrab kom siab zog xws li carbon fiber, fiberglass, reinforced plastic thiab xim tha xim los yog tsis muaj hlau. Heev ua tsawg. Daim ntawv 3M hais tias kev ceev thiab muaj zog ntawm cov khoom siv no qhib lub qhov rooj rau cov kws tsim khoom tsim los tshawb cov qauv tshiab. Robust, ntev ntev txhim kho rau cov ntaub ntawv sib txawv yuav tsum tau muaj cov khoom uas muaj siab zog. Lub modulus ntawm cov khoom siv no yog tsim los muab kev muaj zog thiab ua kom lub cev tau zoo ntawm cov kab ntawv hauv cov hlau.
Muaj ntau txoj kev zoo rau kev siv cov khoom siv sib dhos xws li cov khoom siv pob zeb ntawm Scotch-Weld Multi-Material Composite Urethane Adhesives tsis yog cov kab nrib pleev xws li cov ntsuas, rivets thiab bolts. Drilling qhov ntawm yas substrates rau screws los yog bolts yuav ua rau cracking thiab lwm yam tsis ua hauj lwm ntxov. Cov nplaum tuav lub dag zog thiab ua kom muaj kev ruaj khov ntawm ntau yam hlau, plastics thiab composites. Lub koom txoos ntawm nplaum rau hauv tshuab ua ke yog ib txoj hauv kev yooj yim tshem tawm qhov hnyav ntxiv ntawm cov neeg kho tshuab txuas ntxiv. Cov ntaub ntawv tawm tswv yim zoo kuj ua kom zoo nkauj ntawm cov qauv tsim thaum txo cov sij hawm siv thiab cov nqi txuam nrog cov kev sib koom ua ke.
"Peb pom cov kev siv hauv composites raws li kev loj hlob, tiam sis feem ntau tsis txuag, pheej yig los sis zoo nkauj kom sib sau cov ntaub ntawv nrog cov neeg kho tshuab txuas ntxiv," hais tias Chris Enstrom, 3M Tus Neeg Ua Hauj Lwm Tus Muag Khoom Ua Lag Luam. "Qhov kev siv ntawm 3M Scotch-Weld multi-material composite polyurethane adhesives ua rau nws ua tus txheej txheem tshiab rau kev sib txuas ua ke, tshwj xeeb tshaj yog cov tsheb thauj khoom thiab kev ua kis las."
Scotch-Weld adhesives muaj cov ntxhiab tsis tshua muaj thiab muaj nyob rau hauv ob lub versions nrog ntau lub sij hawm ua haujlwm rau ib thaj tsam ntawm kev siv. Lub 10-feeb ua hauj lwm lub neej yog zoo tagnrho rau lub vas nthiv, cov ntawv thov siv nrog lub sijhawm li ntawm 45 feeb. Txoj haujlwm 30-feeb ua hauj lwm, ua raws li ob xuab moos clamping lub sij hawm, yog tsim los ntawm kev siv nta loj heev hauv siab. Lub sij hawm kho ncua sij hawm muab tus neeg siv sij hawm ntau dua los siv qhov khoom thiab xyuas kom ruaj khov. Txoj haujlwm 10 thiab 30 feeb ua haujlwm feem ntau yog siv tsis yog primer, tsuj kom ua daim ntawv thov.
