Polyurethane iswaafajinta dhagaha
Cudurka polyurethane waxaa loola jeedaa adhesifigga ay kujiraan koox carbambaate ah (- nhcoo -) ama kooxda ISOCYANANATE (- NCO) ee silsiladda Molocalate. Dhaqdhaqaaqa polyurethane waxay u qaybsan yihiin laba qaybood: polyinocyanatate iyo polyanethanethane.polyethane.polyimocate silsiladaha moluculab waxay ku jiraan kooxaha Isocyano (- NH - coo -, sidaa darteed adheliyadaha polyurethane waxay muujinayaan firfircooni sare iyo isbadal. Waxay leedahay isku dhafka kiimikada ee aad u fiican ee sunta ay ku jiraan hydrogen firfircoon, sida walxaha jilicsan sida xumbo, caag, alwaax, maqaarka, iyo qalabka leh, caag, caag, caag, iyo caag.
Isticmaal:
Polyurethane iswaafajinta dhagaha Waxaa loo isticmaali karaa filimka polyester-ka polyester, filimka polyamimide iyo noven-ka aan la isticmaalin.

Gaadiidka iyo keydinta
Gaadiid: Faahfaahin, fadlan tixraac tilmaamaha badbaadada ee laxiriirta.
Baakad: Lh - 101(B / F / H)A: 16 kg / TIN ama 180 kg / baaldi
L - 101(B / F / H)B: 4 kg / tin ama 20 kg / baaldi
Bakhaar: Alaabada asalka ah ee xirxiran waa in lagu keydiyaa meel hadhsan, qabow oo qalalan. Nolosha shelf ee LH - 101(B / F / H)A waa hal sano iyo lh - 101(B / F / H)B waa lix bilood, siday u kala horreeyaan. Alaabta furan waa in la adeegsadaa muddo gaaban gudaheeda.
Astaamaha Substrate
Shuruudaha Filimka Adag, Corrona, daaha, xiisaha qalabka iyo nidaamka xakamaynta heerkulka waa muhiimad muhiim ah oo si toos ah u saameyn doona ama si aan toos ahayn u saameyn doona waxqabadka dhamaadka isticmaalkaisku dhafanalaabada. Wax soo saarka ballaaran, ka hor inta aan imtixaanka rasmiga ahayn ee xarunta iyo kormeerka saxda ah ee ku saabsan waxyaabaha ay lagama maarmaan tahay. Sababo la xiriira xaaladaha dhabta ah ee isticmaalka sheyga ayaa ka baxsan gacanta shirkadda. Sidaa darteed, shirkaddu ma dammaanad qaadi karto isticmaalka dhamaadka.
