Cov kua nplaum rov qab ntawm cov nyom dag feem ntau yog ua los ntawm ob cov ntaub ntawv: styrene butadiene latex lossis pu kua nplaum. Qhov zoo ntawm Pu rov qab nplaum nplaum yog qhov zoo tshaj ntawm styrene butadiene latex, tab sis tus nqi kuj tseem siab. Styrene butadiene latex: Nws yog thawj cov khoom txhawb nqa los ntawm kev ua cov nroj tsuag, nrog kev ua haujlwm siab thiab kev ua haujlwm raug nqi. Tam sim no nws yog cov khoom siv tseem ceeb. Lub zog thiab khi quab yuam ntawm PU nplaum yog ob peb zaug ntau dua li cov khoom siv roj hmab ntuj, nrog rau kev ua haujlwm ntev, xim zoo nkauj, thiab cov ntsiab lus kim. Feem ntau ntawm cov khoom siv turf adhesives tseem yog styrene butadiene latex, uas yog tus nqi tseem ceeb - siv tau rau ntau yam. Tau kawg, polyurethane (PU) adhesives kuj maj mam nce nyob rau hauv xyoo tas los no.
Styrene butadiene latex yog tsim los ntawm polymerization ntawm butadiene thiab styrene. Ib puag ncig tus phooj ywg styrene butadiene latex tsis yog tsuas yog siv tau zoo xwb, tab sis kuj ua rau cov txheej txheem tshuaj tiv thaiv hauv lub reactor tswj kom tau raws li qhov yuav tsum tau ua. Nws yog qhov kev xaiv zoo tshaj plaws rau ib puag ncig tus phooj ywg dag nyom nyom.
PU nplaum yog ib qho anionic raws li waterborne polyurethane dispersion, uas yog ib tug thermally activated nplaum. Yeej tsis muaj kev phom sij rau kev nqus pa, thiab tsis muaj kev phom sij rau lub ntsws thiab lub paj hlwb ntawm tib neeg lub cev. Tsis muaj qhov xwm txheej ntawm kev ua haujlwm raug mob los ntawm kev raug mob ntev -.
Tsis tas li ntawd, vim cov kev cai nruj nruj ntawm lub teb chaws nyob rau hauv no hais txog, muaj yeej tsis muaj toxicity. txwv tsis pub, cov nyom dag feem ntau yog siv rau sab nraum zoov scenes, thiab lawv tsis tsim kev puas tsuaj rau tib neeg lub cev.
