MXC-T120waa awood lehKataliyayaasha jelka organotintaasoo bixisa xasillooni jawi oo wanaagsan isla markaana hagaajisa waxqabadka qaacidooyinka polyurethane. Waa kiciye ku salaysan dibutyltin oo leh firfircooni katalytic sare leh iyo xasillooni hydrolysis oo aad u fiican, taasoo ka dhigaysa mid ku habboon in loo isticmaaloqaababka polyurethane-ka oo keliyaiyoxumbo adag oo polyurethane ah.
Waa maxay Catalysts-ka Organotin Gel?
Kataliyayaasha jelka Organotinwaa isku-darka organotin oo si weyn loogu isticmaalo soo saarista xumbo polyurethane ah, dahaarka, dhejisyada iyo elastomers. Kaaliyayaashani waxay door muhiim ah ka ciyaaraan dardargelinta falcelinta kiimikada inta lagu jiro isku-darka polyurethane, gaar ahaan kor u qaadista habka jelation (ama bogsashada). Kaaliyayaasha organotin ee caadiga ah, sidadibutyltin dilaurate (DBTDL)iyocaprylate-ka stannous, waxay leeyihiin firfircooni xooggan oo kicin ah, taasoo ka dhigaysa kaydka kiimikada ee muhiimka ah ee warshado kala duwan, laga bilaabo dhismaha ilaa wax soo saarka baabuurta.
MXC-T120 waa mid aad u fiicanKataliyayaasha jelka organotiniyadoo leh xasillooni heer sare ah jawiga iyo iska caabinta hydrolysis, hubinta cimrigeeda adeegga iyo isku halaynta jawiyada adag. Doorkeeda ugu weyn ee soo saarista polyurethane waa in la dedejiyo falcelinta u dhaxaysaisocyanatesiyopolyols-ka, laba walxood oo muhiim u ah soo saarista xumbo polyurethane ah.
Sidee loo sameeyaaKatalystayaasha PolyurethaneKa shaqee xumbo adag oo polyurethane ah?
In wax soo saarkaxumbo adag oo polyurethane ah, kiciyeyaasha sida MXC-T120 ayaa lagama maarmaan u ah in si sax ah loo xakameeyoheerarka falcelinta ee isocyanates oo leh polyols iyo biyoFalcelinta dheellitiran waxay hubineysaa in xumbada ay leedahay cufnaanta ugu fiican, daacadnimada qaab-dhismeedka, iyo sifooyinka dahaarka kulaylka kuwaas oo lagu garto xumbo adag oo polyurethane ah.
Xumbo adag oo polyurethane ah ayaa si weyn loo isticmaalaa gudahamuraayadaha dahaarka, qaboojiyeyaasha, iyo qalabka dhismaha, halkaas oo xoogga iyo dahaarka ay yihiin kuwa ugu muhiimsan. MXC-T120 waxay hubisaa in si degdeg ah oo siman loo daadiyo, taasoo suurtogalinaysa soo saarista xumbo waara oo hufan oo leh qashin ama cillad yar.sifooyinka jelitaankaka dhig mid si gaar ah ugu habboon codsiyada u baahan bogsashada degdega ah iyo isku-xidhka dhejiska adag.
MXC-T120: Xal Sare oo loogu talagalay Codsiyada Polyurethane
Qaaciddada ku salaysan dibutyltin ee MXC-T120 waxay leedahay xasillooni hydrolytic ah oo ka sarreysa kaaliyayaasha caadiga ah ee organotin, taasoo la macno ah inay si fiican u shaqeyso xitaa deegaannada qoyan. Tani waxay ka dhigaysaa quudin kiimiko oo macquul ah oo loogu talagalay codsiyada deegaannada qoyan ama kuwa adag, sida dahaarka dibadda ama xumbo badda.
Marka la qaato MXC-T120, soosaarayaasha xumbo adag ee polyurethane waxay heli karaan isku dheelitirnaan badeeco oo heer sare ah, wareegyo wax soo saar oo dhakhso badan iyo waxqabad xumbo oo la xoojiyay.
Shirkadda Kiimikada Mingxu waxay soo saareysay kaaliyayaasha polyurethane in ka badan 20 sano, waxaan leenahay wadada ugu fiican ee habka iyo kooxda xirfadlayaasha ah si loo hagaajiyo loona cusbooneysiiyo alaabada kaaliyayaasha suuqa, sahay badan, macaamiisha soo dhaweynaya inay yimaadaan si ay ula tashadaan.
