Kev siv
Kev noj tshuaj feem ntau yog 1 mus rau 3% ntawm cov ntsiab lus ntawm emulsion.Tus nqi pH ntawm emulsion yog qhov zoo dua 8 txog 9.5.Nws yuav tsum tsis txhob siv nyob rau hauv ib tug acidic nruab nrab.Cov khoom no tsuas yog reacts nrog pawg carboxyl hauv emulsion.Nws yog feem ntau siv nyob rau hauv chav tsev kub, 60 ~ baking nyhuv yog zoo dua ntawm 80 ° C. Tus neeg muas zaub yuav tsum xeem raws li cov kev xav tau ntawm cov txheej txheem.
Cov khoom no yog ob qho tib si sib txuas tus neeg sawv cev.Thaum ntxiv rau qhov system, nws raug nquahu kom siv nws li ntawm 8 mus rau 12 teev.Siv qhov ntsuas kub thiab kev sib haum xeeb Resin system los ntsuas lub lauj kaub lub neej.Nyob rau tib lub sijhawm, cov khoom no muaj me ntsis irritating ammonia tsw.Yuav tsum tau saib xyuas kom tsis txhob muaj kev sib cuag ncaj qha rau ntawm daim tawv nqaij thiab qhov muag.Sim siv nws nyob rau hauv ib qho chaw ventilated.Ua tib zoo saib xyuas lub qhov ncauj thiab qhov ntswg thaum txau.Yuav tsum hnav qhov ncauj qhov ntswg tshwj xeeb, hnab looj tes, khaub ncaws tiv thaiv kom ua haujlwm.
Daim ntawv thov
Dav siv nyob rau hauv dej-raws li thiab ib co kuab tshuaj raws li inks, coatings, siab-rhiab nplaum nplaum, nplaum, thiab lwm yam, nws muaj ib tug tseem ceeb tsis kam mus ntxuav, txhuam, tshuaj, thiab adhesion rau ntau yam substrates.
Qhov kev txhim kho yog tus neeg sawv cev crosslinking belongs rau ib puag ncig tus phooj ywg crosslinking tus neeg saib xyuas, thiab tsis muaj cov khoom phom sij xws li formaldehyde raug tso tawm tom qab crosslinking, thiab cov khoom tiav yog tsis muaj tshuaj lom thiab saj tsis qab tom qab crosslinking.
