Soo-dhaweynta Doorashada Hal-abuurka Polyurethane

Faahfaahinta alaabta

Triethylenediamine (TEDA), oo sidoo kale loo yaqaan 2,2'-diethylenediamine, waa unug dabiici ah oo muhiim ah. Waa caddaan ama midab huruud ah, waxay leedahay urta ammonia, waa hygroscopic, waxayna ku sareyn kartaa heerkulka qolka. Maaddadani waa mid daciif ah oo aasaasi ah waxayna isu rogi kartaa huruud marka ay ka soo nuugayso kaarboon dioxide hawada. Sida kicinta wax ku ool ah oo heer sare ah iyo geeddi-socodka isku-dhafka organic halkaasoo walxaha sahlan ee aan organic ama organic ay ku dhacaan fal-celin kiimikaad si ay u sameeyaan xeryahooda organic, isku-darka organic waxaa loola jeedaa habka loo beddelo walxaha fudud, sida hydrogen iyo carbon dioxide, oo loo beddelo xeryahooda organic ka sii adag iyada oo loo marayo hababka kiimikada. Tusaale ahaan, methanol wuxuu ka samaysan yahay hydrogen iyo carbon dioxide, chloride vinyl waxaa laga soo saaraa ethylene iyo polymerized si loo sameeyo polyvinyl chloride resin, ama terephthalic acid iyo hexamethylenediamine ayaa laga helaa phenol iyada oo loo marayo falcelin badan oo dheeraad ah oo la isku dhejiyo si loo sameeyo polyamide 66 fiilooyinka. Isku-dhafka dabiiciga ah ee casriga ah ayaa si ballaaran loogu dabaqay meelo badan sida resins, caag, fiilooyinka, midabada, daawooyinka, shidaalka, iyo udgoonka. Tan iyo markii Friedrich Wöhler uu markii ugu horreysay ka soo saaray HOL ee ammonium cyanate inorganic 1828-kii, isku-dhafka organic wuxuu si tartiib tartiib ah u horumaray mid ka mid ah laamaha asaasiga ah ee kiimikada. Ka dib 1970-yadii, iyada oo horumarka laga gaaray cilmi-baarista habka fal-celinta, falanqaynta is-waafajinta, photochemistry, iyo hababka falanqaynta jireed ee kala duwan, gaar ahaan soo jeedinta mabda'a ilaalinta sumowga molecular orbital, horumarinta alaabta dabiiciga ah ee adag iyo isku-dhafka stereoselective ayaa si degdeg ah loo dardargeliyay. Eeg dhex dhexaadiyayaal badan Triethylenediamine waxaa si weyn loogu isticmaalaa soo saarista xumbo polyurethane, elastomers, iyo alaabta caaga ah. Waxa kale oo ay kicisaa falcelinta polymerization sida ethylene oxide iyo ethylene, waxaana loo isticmaali karaa in lagu farsameeyo walxaha xasilinta iftiinka. Ka-soo-saarkeeda waxa loo isticmaalaa warshadaha sida daxalka inhibitors iyo emulsifiers.

Codsiga alaabta

Triethylenediamine (TEDA) waa iskudhis organic oo muhiim ah oo si weyn loogu isticmaalo dhinacyada injineernimada kiimikada iyo sayniska alaabta. 1. Warshadaha Polyurethane: Sida kicinta wax ku oolka ah, waxaa loo isticmaalaa soo saarista jilicsanaanta jilicsan, jilicsan, iyo caagadaha xumbada poliurethane ee adag, kor u qaadida dheellitirka gelation iyo falcelinta xumbo iyo kor u qaadista xasilloonida qaabdhismeedka iyo sifooyinka farsamada ee xumbo. Waxa kale oo loo isticmaalaa soo saarista alaabta polyurethane sida elastomers iyo dahaarka. 2. Isku-dhafka dabiiciga ah: Dhexdhexaadiyaha isku-dhafka dabiiciga ah, waxaa loo isticmaalaa isku-dhafka walxaha xasilinta iftiinka, soo-saareyaasha wax-soo-saarka cayayaanka, iwm. 3. Qalabaynta falcelinta polymer-ka: Waxaa loo istcimaalaa sidii fal-celinta ethylene-polymerization-ka, kataliyaha ethylene oxide-polymerization-ka, iyo kicinta acrylonitrile polymerization catalyst, kor u qaadida horumarka falcelinta polymerization. 4. Beeraha kale: Waxa kale oo lagu codsadaa in daawaynta xabagta epoxy, daro electroplating non-chlorine, biyo kululeeyaha daxalka inhibitors daaweynta, iwm sannadihii la soo dhaafay, ay codsiga in qalab cusub sida baytariyada lithium iyo fluorescent walxaha ka kooban ayaa sidoo kale soo jiidatay dareenka.

Xaaladda kaydinta

Triethylenediamine waa in lagu kaydiyaa weel xidhan oo ku jira bakhaar qabow, engegan oo hawo fiican leh, kana fog ilaha dabka, ilaha kulaylka, iyo iftiinka, lagana soocaa walxaha acidic ee kaydinta iyo gaadiidka.

Xaaladaha deegaanka: heerkulka lagu taliyey ee kaydinta ayaa ka hooseeya 30 ℃. Ka fogow iftiinka qorraxda tooska ah iyo heerkulka sare, kana ilaali nuugista qoyaanka, deelqaafka, ama burburka.

Xiritaanka baakadaha: Isticmaal baakadaha aan qoyaanka lahayn (sida 25kg/koonteenarada ama sanduuqyada kartoonada) si aad u hubiso in weelka si fiican loo xidhay, ka hortagga nuugista qoyaanka, kacsanaanta, ama isbeddelka midabka sababtoo ah falcelinta CO₂ ee hawada.

Kaydinta go'doominta: Ku kaydi si gooni ah walxaha aan isqaban karin sida oksidants xooggan iyo aashitada xoogga leh si looga fogaado taabashada maqaarka ama indhaha. Qalabka ilaalinta waa in la gashado inta lagu jiro hawlgalka.

Taxadarrada gaadiidka: Inta lagu jiro gaadiidka, ka hortag burburka makaanikada, ku hay baakadaha mid nadiif ah, kana fogow heerkulka sare iyo jawiga qoyan.

Kiimikadayada sida aadka ah loo iibiyo waxaa ka mid ah dareerayaasha warshadaha iyo dhexdhexaadiyeyaasha kiimikaad, sida Taxanaha Alcohol, Taxanaha Ether, Esters, Precursor Series, Acid-Ester Solvents, Bacrimiyeyaasha NPK-Biyaha-Milan, iyo Kiimikada kale ee Warshadaha. Alaabooyinkani waxay ka kooban yihiin sahay deggan, nadiifnimo la isku halayn karo, iyo heerar tayo leh oo joogto ah. Weydiinta waa la soo dhawaynayaa.
