Bis(2,6-diisopropylphenyl) karbodiimideCAS 2162-74-5waa monomeric carbodiimide, nooc wakiil ah oo ka hortagga hydrolysis kaas oo leh astaamo saafi ah oo sare, midab khafiif ah, aan ur lahayn iyo firfircooni sare. Bis(2,6-diisopropylphenyl) carbodiimide waxaa si weyn loogu isticmaalaa agabka sida polyester polyol, naylon, balaastikada injineernimada ee ka kooban kooxda ester, polyurethane elastomers, dhejisyo, nidaamyada dahaarka, iyo saliidda saliidaynta. Bis(2,6-diisopropylphenyl) carbodiimide wuxuu si wax ku ool ah u joojin karaa hydrolysis-ka agabkaas wuxuuna xasilin karaa sifooyinka farsamada bilowga ah. Isla mar ahaantaana,bcarboodiimide (2,6-diisopropylphenyl) ayaa sidoo kale xannibi kara joojinta firfircoon ee carboxyl-ka ee walxaha polyester-ka. Dayactir walxaha polyester-ka iyo polyurethane-ka ee dhaawacan,bwaa (2,6-diisopropylphenyl) carboodiimide wuxuu dheereyn karaa cimriga adeegga ee alaabada polymer-ka xaaladaha shaqada ee adag sida heerkulka sare iyo qoyaanka.

Dhanka cilmiga agabka, bis(2,6-diisopropylphenyl)carbodiimide, sida monomeric carbodiimide anti-hydrolysis stabilizer, waxay noqotay diiradda warshadaha sababtoo ah waxqabadkeeda wanaagsan iyo rajada ballaaran ee isticmaalka.

Marka hore,carboodiimide bis(2,6-diisopropylphenyl) waxaa si weyn loogu isticmaalaa polyurethane elastomers (sida TPU, CPU), dhejisyada, xalalka kelida ah iyo elastomers-ka Microporous, iwm. Meelahan, iyadoo lagu darayo 0.3-2.0% bis(2,6-diisopropylphenyl)carbodiimide, Nolosha adeegga ee badeecadda si weyn ayaa loo hagaajin karaa, iyadoo la kordhin karo ilaa 1 ilaa 3 jeer.

Marka labaad, inta lagu jiro habka wax ka beddelka walxaha polyester-ka sida PET/PBT, ku darista bis (2,6-diisopropylphenyl) carboodimide waxay yareyn kartaa qiimaha aashitada ee polyester-ka. Horumar muhiim ah oo ku yimaada tayada agabka waxaa lagu gaari karaa iyadoo la yareeyo tirada lagu daray, taasoo kordhinaysa xasilloonida muddada dheer ee agabka.

Marka laga soo tago in loo isticmaalo sidii wakiil ka hortagga hydrolysis, bis(2,6-diisopropylphenyl)carbodiimide sidoo kale waxaa loo isticmaali karaa sidii qalab wax lagu farsameeyo si loogu falceliyo asiidhyada carboxylic ee la soo saaro inta lagu jiro habka extrusion-ka. falcelinta, ka hortagga dhimista miisaanka molecular-ka, daciifinta dhaawaca soo gaara polymer-ka inta lagu jiro farsamaynta, taasoo sahlaysa in la shaqeeyo iyo hagaajinta badbaadada farsamaynta marka la barbar dhigo hababka kale.

Intaa waxaa dheer, PLA balaastikada deegaanka u fiican ee baaba'aysa, iska caabbinta hydrolysis-ka oo liidata ayaa had iyo jeer ahayd caqabad weyn oo xaddidaysa codsigeeda ballaaran. PLA si fudud ayaa loo dhimaa deegaannada qoyan, taasoo saamaysa waxqabadkeeda iyo cimrigeeda. Si kastaba ha ahaatee, iyadoo lagu darayo 0.3-0.5% bis(2,6-diisopropylphenyl)carbodiimide PLA, iska caabbinta biyaha waxaa si weyn loo hagaajin karaa 3-7 jeer, taasoo si wax ku ool ah u ballaarinaysa.tmeelaha codsiga ee PLA.

Wadarta guudmary, bis(2,6-diisopropylphenyl)carbodiimide, oo ah xasiliye ka hortagga hydrolysis-ka oo waxqabad sare leh, ayaa muujisay awood ballaaran oo codsi iyo karti ah oo ku saabsan cilmiga agabka. qiimaha.ItSifooyinka jireed iyo kuwa kiimikada ee aadka u fiican, noocyada kala duwan ee codsiyada, iyo xalalka la beegsanayo ee agabka gaarka ah (sida PLA) waxay ka dhigaan bis(2,6-diisopropylphenyl)carbodiimide hoggaamiye xasilinta agabka. Iyadoo la horumarinayo sayniska agabka iyo wacyigelinta sii kordheysa ee ilaalinta deegaanka, bis(2,6-diisopropylphenyl)carbodiimide iyo alaabada la midka ah ayaa la filayaa in la hormariyo oo lagu dabaqo goobo badan.
