Chothandizira cha bismuth chachilengedwe
MOFAN B2010 ndi chothandizira chamadzimadzi chachikasu cha organic bismuth. Chingathe kulowa m'malo mwa dibutyltin dilaurate m'mafakitale ena a polyurethane, monga PU leather resin, polyurethane elastomer, polyurethane prepolymer, ndi PU track. Chimasungunuka mosavuta m'machitidwe osiyanasiyana a polyurethane okhala ndi zosungunulira.
● Ikhoza kulimbikitsa reaction ya -NCO-OH ndikupewa reaction ya mbali ya gulu la NCO. Ikhoza kuchepetsa mphamvu ya reaction ya madzi ndi gulu la -NCO (makamaka mu dongosolo la sitepe imodzi, ikhoza kuchepetsa kupanga kwa CO2).
● Ma asidi achilengedwe monga oleic acid (kapena kuphatikiza ndi organic bismuth catalyst) amatha kulimbikitsa momwe gulu la amine-NCO (lachiwiri) limagwirira ntchito.
● Mu kufalikira kwa PU pogwiritsa ntchito madzi, zimathandiza kuchepetsa momwe madzi ndi gulu la NCO zimagwirira ntchito.
●Mu dongosolo la chinthu chimodzi, ma amine omwe amatetezedwa ndi madzi amatulutsidwa kuti achepetse zotsatira zoyipa pakati pa madzi ndi magulu a NCO.
MOFAN B2010 imagwiritsidwa ntchito pa utomoni wa chikopa cha PU, polyurethane elastomer, polyurethane prepolymer, ndi PU track etc.

30kg/Chitini kapena 200 kg / ng'oma kapena malinga ndi zosowa za makasitomala
Malangizo okhudza kugwiritsa ntchito bwino:Gwirani motsatira malamulo a Mulungu okhudza ukhondo ndi chitetezo m'mafakitale. Pewani kukhudza khungu ndi maso. Perekani mpweya wokwanira komanso/kapena utsi wokwanira m'zipinda zogwirira ntchito. Azimayi oyembekezera ndi oyamwitsa sangakumane ndi mankhwalawa. Ganizirani malamulo a dziko lonse.
Njira Zoyezera Ukhondo:Kusuta fodya, kudya ndi kumwa kuyenera kuletsedwa pamalo opaka mankhwala. Sambani m'manja musanayambe nthawi yopuma komanso kumapeto kwa tsiku logwira ntchito.
Zofunikira pa malo osungiramo zinthu ndi zotengera:Sungani kutali ndi kutentha ndi magwero oyatsira moto. Tetezani ku kuwala. Sungani chidebecho motseka bwino pamalo ouma komanso opumira bwino.
Malangizo okhudza chitetezo ku moto ndi kuphulika:Sungani kutali ndi zinthu zomwe zimayambitsa moto. Osasuta fodya.
Malangizo okhudza kusungira zinthu zambiri:Sizigwirizana ndi zinthu zophera oxidants.
