Bis (2,6-diisopropylfenyl) karbodiimideCAS 2162-74-5waa monomeric carbodiimide , wakiil kala duwan oo ka mid ah wakiilka anti-hydrolysis kaas oo leh sifooyinka nadiifnimada sare, midabka iftiinka, aan lahayn ur iyo dhaqdhaqaaq sare. Bis (2,6-diisopropylfenyl) carbodiimide waxaa si weyn loogu isticmaalaa qalabka sida polyester polyol, naylon, balaastikada injineernimada oo ay ku jiraan kooxda ester, polyurethane elastomers, dhejisyada, nidaamyada daahan, iyo saliidda saliidda. Bis (2,6-diisopropylphenyl) karbodiimide waxay si wax ku ool ah u joojin kartaa hydrolysis ee qalabkan oo kale waxayna dejin kartaa sifooyinka farsamada ee bilowga ah. Isla markaana.bwaa (2,6-diisopropylfenyl) karbodiimide waxay sidoo kale xannibi kartaa joojinta karboksylka firfircoon ee walxaha polyesterka. Dayactirka polyester-ka iyo walxaha polyurethane ee burburay,bwaa (2,6-diisopropylphenyl) karbodiimide waxay sii dheerayn kartaa nolosha adeegga alaabada polymer ee xaaladaha adag ee shaqada sida heerkulka sare iyo qoyaanka..

Dhinaca sayniska agabka, bis (2,6-diisopropylfenyl) karbodiimide, sida monomeric carbodiimide anti-hydrolysis stabilizer, waxay noqotay diiradda warshadaha waxqabadkeeda wanaagsan iyo rajada codsiga ballaaran.

Marka hore,bis (2,6-diisopropylphenyl) carbodiimide waxaa si weyn loogu isticmaalaa elastomer polyurethane (sida TPU, CPU), xabagta, xalalka keligood ah iyo elastomers Microporous, iwm. Goobahan, adoo ku daraya 0.3-2.0% bis(2,6-diisopropylfenyl)carbodiimide, nolosha adeegga alaabta si weyn ayaa loo wanaajin karaa, iyada oo la kordhinayo ilaa 1 ilaa 3 jeer.

Marka labaad, inta lagu jiro habka wax ka beddelka alaabta polyesterka sida PET/PBT, ku darida bis (2,6-diisopropylfenyl) carbodiimide waxay yarayn kartaa qiimaha acid ee polyesterka. Horumarka la taaban karo ee tayada maaddada waxaa lagu gaari karaa qaddar hoose oo lagu daro, taasoo kordhinaysa xasilloonida alaabta.

Waxa intaa dheer in loo isticmaalo sida wakiilka anti-hydrolysis, bis (2,6-diisopropylfenyl) karbodiimide waxa kale oo loo isticmaali karaa gargaar processing si ay ula falgalaan asiidh-carbosilic acids soo saaray inta lagu guda jiro habka extrusion. falcelinta, ka hortagga dhimista miisaanka kelli, daciifinta dhaawaca polymer inta lagu guda jiro processing, fududaynta in ay shaqeeyaan iyo hagaajinta ammaanka processing marka la barbar dhigo hababka kale.

Intaa waxaa dheer, PLA caag bay'ada u saaxiibka ah biodegradable, caabbinta hydrolysis liidata ayaa had iyo jeer ahaa caqabad weyn oo xaddidaysa codsigeeda ballaaran. PLA si sahal ah bay u xaalufisay deegaanka qoyan, taas oo saamaynaysa waxqabadkeeda iyo cimrigeeda. Si kastaba ha noqotee, marka lagu daro 0.3-0.5% bis (2,6-diisopropylphenyl) karbodiimide PLA, caabbinta biyaha ayaa si weyn loo wanaajin karaa 3-7 jeer, si wax ku ool ah u ballaarintatwuxuu ku jiraa codsiyada PLA.

Isku soo wada duuboomary, bis (2,6-diisopropylphenyl) karbodiimide, oo ah hawl-qabad sare oo ka-hortagga-hydrolysis stabilizer, ayaa muujisay suurtagalnimada codsiga ballaaran iyo kartida berrinka sayniska qalabka. qiimaha.Its sifooyinka ugu fiican ee jirka iyo kiimikaad, codsiyo kala duwan, iyo xalalka la beegsanayo ee alaabta gaarka ah (sida PLA) waxay ka dhigaan bis (2,6-diisopropylfenyl) karbodiimide hogaamiyaha dejinta alaabta. Iyadoo horumarinta joogtada ah ee sayniska agabka iyo wacyiga sii kordhaya ee ilaalinta deegaanka, bis(2,6-diisopropylfenyl)carbodiimide iyo alaabteeda la midka ah ayaa la filayaa in la hormariyo laguna dabaqo dhinacyo badan.
