PTSI p-toluenesulfonyl isocyanate CAS 4083-64-1 Tosyl isocyanate
MSI (PTSI), p-toluenesulfonyl isocyanate, oo ah monoisocyanate si caadi ah loo isticmaalo, oo ah iskudhis aad u falceliyay oo si weyn loogu isticmaalo sidii wakiil fuuq-baxa alaabada kiimikada, sida dareerayaasha, buuxinta, midabada iyo meelaha daamurka. Waa qalab qoyaan u qoda dahaarka polyurethane (PU) ee ku salaysan dareeraha, shaabadayn, dhejisyo iyo dhexdhexaad ka mid ah kiimikooyin kala duwan oo muhiim u ah warshadaha.
p-toluenesulfonyl isocyanate (PTSI) waxay ka hortagtaa falcelinta aan loo baahnayn ee rinjiga iyo dahaarka, sidaa darteed, waxay u oggolaanaysaa qaacideeyayaasha inay soo saaraan polyurethanes tayo sare leh. Iyadoo la adeegsanayo PTSI soo saarista rinjiyada polyurethane, luminta dhalaalka, huruudaynta iyo xumbo falcelin leh oo ay keento dusha qoyan ee nidaamka ayaa dhammaantood la dhimayaa. p-toluenesulfonyl isocyanate waxay sidoo kale noqon kartaa wax lagu daro xasilinta walxaha qoyaanka daaweeya si looga hortago xumaanshaha ama/iyo midab-beddelka inta lagu jiro kaydinta.
MSI (PTSI) waxay la falgashaa biyaha, iyadoo soo saarta kaarboon laba ogsaydh taasoo keenta sameynta alaabada falgalka kuwaas oo ku milma qaab-dhismeedka rinjiga caadiga ah. Qiyaastii 12g oo ka mid ah xasiliyaha ayaa aragti ahaan looga baahan yahay falcelinta 1g oo biyo ah. Si kastaba ha ahaatee, waayo-aragnimadu waxay muujisay in falcelintu ay waxtar badan leedahay marka ay jirto xaddi badan oo MSI (PTSI). Waafaqsanaanta isku-xidhka rinjiga waa in had iyo jeer la tijaabiyaa ka hor.
p-toluenesulfonyl isocyanate waxaa lagu talinayaa in loo isticmaalo sidii jebin silsilad ah inta lagu jiro polymerization iyo sidii ka saarista kooxaha shaqada ee aan loo baahnayn ee ku jira walxaha ceeriin ee PU. Dahaarka dhuxusha ee PU, MSI waxaa loo isticmaali karaa in lagu dhexdhexaadiyo kooxaha shaqada ee amines iyo OH iyo in laga saaro biyaha ku jira tar si looga fogaado xumbo iyo jelitaanka dhicis ah marka tar lagu qaso prepolymer-ka PU.
Astaamaha:
- Waxay baabi'isaa saameynta qoyaanka waxayna ka hortagtaa dhibaatooyinka la xiriira qoyaanka ee dahaarka polyurethane
- Dheef-dhalasho hoose, isocyanate monofunctional ah kaas oo si kiimiko ah ula falgala biyaha si uu u sameeyo amide aan firfircoonayn
- Waxaa loo isticmaalaa fuuq-baxa dareerayaasha, buuxinta, midabada iyo daasadaha bituminous
- Waxay hagaajisaa xasilloonida kaydinta ee diisocyanates ka dhanka ah kala-baxa iyo midab-beddelka
- Waxay ka saartaa qoyaanka lagu daray dareerayaasha, midabada, iyo buuxinta nidaamyada PU-ga ee hal-qaybood iyo laba-qaybood leh
MSI (PTSI) waxaa loo isticmaalaa sidii xasiliye loogu talagalay agabka qoyaanka daaweeya. Waxay ka hortagtaa falcelin aan loo baahnayn oo ku timaadda rinjiga iyo dahaarka. p-toluenesulfonyl isocyanat waxaa badanaa loo isticmaalaa meelaha soo socda:
- Xabagyo iyo shaabadayn polyurethane ah oo hal qayb ah iyo laba qaybood ah.
- Dahaarka iyo rinjiyada polyurethane-ka hal-qayb ah iyo kuwa laba-qayb ah.
- Dareeraha
- Midabyo
- Buuxiyaasha

Kaydinta iyo rarista: PTSI waa mid u nugul qoyaanka sidaas darteed waa in had iyo jeer lagu kaydiyaa weelal asal ah oo si adag loo xiray heerkul u dhexeeya 5°C iyo 30°C. Marka la furo, weelasha waa in dib loo xidhaa isla markiiba ka dib marka laga saaro badeecadda. Ka fogow aalkolada, saldhigyada adag, amiinada, iyo walxaha oksaydhka ee xooggan.
Muddada kaydinta: 6 bilood laga bilaabo taariikhda wax soo saarka.
