Organic bismuth catalyst
MOFAN B2010 imhando ye bismuth ine ruvara rweyero uye inonyunguduka. Inogona kutsiva dibutyltin dilaurate mune mamwe maindasitiri e polyurethane, akadai sePU dehwe resin, polyurethane elastomer, polyurethane prepolymer, uye PU track. Inonyungudika nyore nyore mumhando dzakasiyana dze polyurethane dzine solvent-based solvent.
● Inogona kukurudzira reaction ye -NCO-OH uye kudzivirira reaction yedivi reNCO group. Inogona kuderedza mhedzisiro ye reaction yemvura uye ye -NCO group (kunyanya mu one-step system, inogona kuderedza kugadzirwa kweCO2).
● Maasidhi eorganic akadai se oleic acid (kana kuti pamwe chete ne organic bismuth catalyst) anogona kukurudzira kuita kweboka re (secondary) re amine-NCO.
● Mukupararira kwePU kwakavakirwa mumvura, zvinobatsira kuderedza mativi emvura neboka reNCO.
●Mune imwe chete ine chikamu chimwe chete, maamine akadzivirirwa nemvura anoburitswa kuderedza mafambiro ekunze pakati pemvura nemapoka eNCO.
MOFAN B2010 inoshandiswa paPU dehwe resin, polyurethane elastomer, polyurethane prepolymer, uye PU track nezvimwewo.

30kg/Can kana 200 kg / drum kana zvichienderana nezvinodiwa nevatengi
Mazano ekubata zvakachengeteka:Bata zvinoenderana nemutemo wekuchengetedza uye hutsanana hwemuindasitiri. Dzivisa kusangana neganda nemaziso. Isa mhepo yakakwana uye/kana utsi hwemhepo mumakamuri ebasa. Vakadzi vane pamuviri nevanoyamwisa havafanirwe kusangana nechigadzirwa ichi. Funga nezvemutemo wenyika.
Matanho Ehutsanana:Kusvuta, kudya nekunwa hazvifanirwe kurambidzwa munzvimbo inoisirwa mushonga. Geza maoko usati waenda kunonwa mushonga uye pakupera kwezuva rebasa.
Zvinodiwa panzvimbo dzekuchengetera zvinhu nemidziyo:Chengeta kure nekupisa uye zvinhu zvinobatidza moto. Dzivirira kubva kuchiedza. Chengeta mudziyo wakavharwa zvakanaka munzvimbo yakaoma uye ine mhepo inofefetera zvakanaka.
Mazano ekudzivirira kubva kumoto nekuputika:Chengeta kure nezvinhu zvinobatidza moto. Usasvuta fodya.
Mazano ekuchengetedza zvinhu zvakajairika:Hazvienderane nevanoita oxidizing.
