Glue rau Wood Joining

Winsir Glue for Wood Joining yog ib qho kev ua haujlwm siab - nplaum nplaum ua rau cov chaw ua haujlwm ntoo. Ntau tus neeg ua haujlwm ntoo cuam tshuam nrog luv luv offcuts thiab cov khoom seem. Cov ntaub ntawv no feem ntau mus pov tseg. Peb cov kua nplaum rau cov ntoo sib koom ua cov khoom luv luv no rau hauv cov rooj zaum ntev, siv tau. Koj tuaj yeem siv ntiv tes sib koom ua ke los yog kev sib koom ua ke. Lub board tiav lawm muaj lub zog uas nyob ze rau cov khoom ntoo. Peb tau pab lub txee qhov rooj Hoobkas hauv Shandong. Lawv tau siv pov tseg 30% ntawm lawv cov khoom luv luv. Tom qab lawv pib siv peb cov kua nplaum rau kev sib koom ua ke, lawv cov txiaj ntsig tau nce los ntawm 20%. Cov khoom no ua tau raws li tus qauv Japanese JAS. Cov kab nplaum yog qhov tseeb thiab yuav luag tsis pom. Ntau lub tuam txhab xa khoom rooj tog siv cov kua nplaum no rau cov ntoo koom ua ke kom dhau qhov kev kuaj xyuas zoo hauv Nyiv, Europe, thiab Asmeskas.

Winsir Glue for Wood Joining siv ob -ib feem. Lub ntsiab tivthaiv yog siab -molecular- hnyav hloov polyvinyl acetate (PVAc) emulsion. Lub hardener yog hydrophilic polyisocyanate. Koj sib tov lawv ntawm qhov sib piv ntawm 100:15 los ntawm qhov hnyav. Cov khoom tseem ceeb muaj cov ntsiab lus ntawm 50% ± 2%. Ntawm 25 degree, viscosity nyob nruab nrab ntawm 8,000 thiab 15,000 centipoise. Tus nqi pH nyob ntawm 5.5 txog 6.5. Lub hardener muaj cov ntsiab lus NCO zoo txog li 15%. Tom qab sib tov, koj muaj lub sijhawm ua haujlwm ntawm 30 mus rau 45 feeb ntawm 25 degree. Cov kua nplaum no rau cov ntoo koom nrog tsis muaj formaldehyde. Nws ua tau raws li CARB Phase 2 tus qauv. Lub refractive index ntawm cov nplaum yog kho kom haum cov ntoo qhib thiab maple. Qhov no yog vim li cas cov kua nplaum kab nyob twj ywm kom meej thiab pob tshab.

Peb tau sim Winsir Glue rau Wood Joining kom meej. Lub zog sib txuas raug kuaj raws li ASTM D{12}}905 ntawm North American maple. Lub zog shear ncav cuag 16 txog 19 MPa. Cov ntoo tsis ua haujlwm yog ntau dua 95%. Qhov no txhais tau tias cov kua nplaum sib koom ua ke muaj zog dua li ntoo nws tus kheej. Rau cov dej tsis kam, cov khoom ua tau raws li EN 204 D4 qib. Nws dhau qhov boil{13}}dry-boil cycle test. Lub zog tuav tus nqi yog siab dua 85%. Qhov no ua rau nws tsim nyog rau cov rooj tog zaum sab nraum zoov thiab chav da dej. Rau kev kho ceev, ntawm qhov kub siab tshaj 20 degree, koj tuaj yeem tshem tawm lub siab tom qab 45 mus rau 60 feeb. Lub zog tag nrho yog ncav cuag hauv 24 teev. Qhov no yog 30% sai dua li cov nplaum nplaum rau kev sib koom ua ke. Txhua batch peb tsim los ntawm kev kuaj tsis ua haujlwm ntawm cov ntoo thiab kev ntsuas dej tsis kam.
