PTSI p-toluenesulfonyl isocyanate CAS 4083-64-1 Tosyl isocyanate
MSI (PTSI), p-toluenesulfonyl isocyanate, ib qho monoisocyanate uas siv ntau, ib qho tshuaj uas muaj zog heev uas siv dav ua tus neeg sawv cev dehydrating hauv cov khoom siv tshuaj, xws li cov kuab tshuaj, cov khoom sau, cov xim thiab cov chaw pitch tar. Ua ib qho khoom siv los ntxuav cov dej noo rau cov tshuaj polyurethane (PU) coatings, sealants, adhesives thiab ua ib qho nruab nrab ntawm ntau yam tshuaj tseem ceeb hauv kev lag luam.
p-toluenesulfonyl isocyanate (PTSI) tiv thaiv kev tsis zoo ua ntej ntawm kev pleev xim & txheej, yog li ntawd, nws tso cai rau cov neeg tsim cov polyurethanes zoo. Los ntawm kev siv PTSI hauv kev tsim cov xim polyurethane, qhov poob ntawm gloss, yellowing thiab reactive ua npuas ncauj los ntawm qhov chaw ntub dej hauv lub cev raug txo kom tsawg. p-toluenesulfonyl isocyanate kuj tseem tuaj yeem yog cov khoom siv stabilizer rau cov khoom siv noo noo kom tiv thaiv kev puas tsuaj lossis / thiab discoloration thaum khaws cia.
MSI (PTSI) ua rau dej sib xyaw, muab cov pa roj carbon dioxide tawm thiab ua rau cov khoom sib xyaw uas yaj tau hauv cov xim pleev ib txwm muaj. Kwv yees li 12g ntawm cov tshuaj stabilizer yog qhov xav tau rau kev sib xyaw nrog 1g dej. Txawm li cas los xij, kev paub dhau los tau qhia tias qhov kev sib xyaw ua haujlwm zoo dua yog tias muaj MSI (PTSI) ntau dhau. Kev sib raug zoo nrog cov xim khi yuav tsum tau sim ua ntej.
p-toluenesulfonyl isocyanate raug pom zoo kom siv ua tus txiav cov saw hlau thaum lub sijhawm polymerization thiab ua tus tshem tawm cov pab pawg ua haujlwm tsis xav tau hauv PU raw cov ntaub ntawv. Hauv cov txheej txheem PU coatings, MSI tuaj yeem siv los ua kom cov amines thiab OH ua haujlwm tsis muaj zog thiab tshem tawm cov dej hauv tar kom tsis txhob muaj npuas thiab gelation ua ntej thaum tar sib xyaw nrog PU prepolymer.
Nta:
- Tshem tawm cov teebmeem ntawm cov av noo thiab tiv thaiv cov teeb meem cuam tshuam nrog cov av noo hauv polyurethane coatings
- Cov viscosity qis, monofunctional isocyanate uas tshuaj lom neeg reacts nrog dej los ua ib qho inert amide
- Siv rau kev qhuav cov kuab tshuaj, cov khoom sau, cov xim thiab cov bituminous tars
- Txhim kho qhov ruaj khov ntawm diisocyanates tiv thaiv kev lwj thiab kev hloov pauv xim
- Tshem tawm cov dej noo uas tau qhia nrog cov kuab tshuaj, cov xim, thiab cov khoom sau hauv Ib-component thiab Dual-component PU systems
MSI (PTSI) yog siv los ua tus stabilizer rau cov ntaub ntawv uas ua kom cov dej noo. Nws tiv thaiv kev ua tsis zoo ua ntej ntawm cov xim pleev xim & txheej. p-toluenesulfonyl isocyanat feem ntau siv rau hauv qab no:
- Cov nplaum polyurethane ib qho thiab ob qho khoom sib xyaw thiab cov khoom sib xyaw.
- Cov txheej txheem polyurethane ib qho thiab ob qho tib si.
- Cov kuab tshuaj
- Cov xim
- Cov khoom sau
- Cov tshuaj reagents

Kev Khaws Cia thiab Kev Thauj Mus Los: PTSI yog cov khoom uas rhiab heev rau dej noo thiab yog li ntawd yuav tsum khaws cia rau hauv cov thawv qub uas kaw ruaj ruaj ntawm qhov kub ntawm 5°C thiab 30°C. Thaum qhib lawm, cov thawv yuav tsum tau rov kaw dua tam sim ntawd tom qab txhua zaus tshem tawm cov khoom. Khaws kom deb ntawm cov cawv, cov hauv paus muaj zog, cov amines, cov neeg sawv cev oxidizing muaj zog.
Lub neej txee: 6 lub hlis txij li hnub tsim khoom.
