Waxyaabaha kiimikada
Dareere saliid leh oo hufan oo aan midab lahayn oo leh ur yar oo amin ah.Waxay noqon kartaa mid isku dhafan oo leh biyo, aalkolo, ether, ester, ketone, hydrocarbon halogenated, hydrocarbon udgoon.
dulmar
N-methyl pyrrolidinone ee gaaban, caanaha molecular: C5H9NO, Ingiriis: 1-methyl-2-PyrrolidinOne, muuqaalku waa mid aan midab lahayn ilaa dareeraha huruuda ah ee huruuda ah, oo leh ur yar oo ammonia ah, oo lagu khaldi karo biyo qayb kasta, ku milma ether, acetone iyo ester, hydrocarbon halogenated, hydrocarbon udgoon iyo dareerayaasha kale organic, Ku dhawaad gebi ahaanba qasan dhammaan dareerayaasha Kiimikada, barta karkaraya 204 ℃, flash dhibic 91 ℃, hygroscopic, guryaha kiimikada deggan, ma daxaleeyay in birta carbon, aluminium, wax yar daxaloobay ilaa naxaas.Waxay leedahay faa'iidooyinka viscosity hoose, kiimikada wanaagsan iyo xasiloonida kulaylka, polarity sare, isbedel hoose, miscibility aan xad lahayn oo biyo ah iyo dareere organic badan, iwm. Alaabta Tani waa daroogada micro ah, xoojinta xadka la ogol yahay ee hawada waa 100PP.
Isticmaalka ugu muhiimsan
(1.) Heerka warshadaha:
Sifaynta saliidda, saliidda saliidda barafaynta saliidda, desulfurization syngas, qalabka dahaarka elektiroonigga ah, herbicides beeralayda, lagu daro sunta cayayaanka, soo kabashada gaaska dabada PVC, daahan heer sare ah, khad, wax soo saarka midabka ee daro iyo kala firdhiyey.Tusaale ahaan, loo isticmaalo in lagu soo saaro udugga saliidda saliidda si loo gaaro ujeedada sifaynta saliidda;Sababtoo ah milanka weyn ee xabagta NMP, sida dareeraha farsamaynta resin waxaa si gaar ah loogu isticmaali karaa soo saarista daaha, rinjiga sagxadda, varnish, filimka daahan isku dhafan, qalabka isku-dhafka ah ee daboolka xargaha xargaha, dharka fiber-ka iyo xabagta iyo alaabta kale.
(2.) Heerka caadiga ah:
Soo saarista iyo soo kabashada alaabta dabiiciga ah ee aasaasiga ah, sida soo saarista acetylene iyo butadiene, isoprene, aromatics iyo soo saarista kale.Waxaa loo isticmaali karaa dareere ahaan si looga soo kabsado acetylene gaaska dabiiciga ah ama nafta nafta pyrolysis gaaska.Sida soosaarayaasha loogu talagalay kala-soocidda iyo soo kabashada butadiene-nadiifinta sare ee dillaaca C4 hydrocarbon, heerka soo kabashada waa 97%, daahirsanaanta butadiene ee la soo kabsadayna waa 99.7%.Sida soosaarayaasha soo kabashada isoprene-nadiifinta sare ee dillaaca C5 hydrocarbon, nadiifinta soo kabashada isoprene waa 99%.Sababtoo ah milanka sare iyo cadaadiska uumiga hooseeya ee aromatics, heerka luminta wakiilka soo saarida ayaa hooseeya iyo heerka soo kabashada ee udugga ayaa sarreeya.
(3.) Heerka reagent:
Wareegga isku dhafan, disk adag iyo shuruudaha kale ee xakamaynta adag ee ions birta iyo qaybaha warshadaha ee deoiling, degreasing, dewaxing, polishing, ka hortagga miridhku, rinjiga, sida dareeraha saarista photoresist, IC qalabka saxda ah warshadaha semiconductor, LCD qalabka crystal dareere, PCB-ga daabacan guddiga wareegga, nadiifinta disk adag;Sidoo kale dareeraha xuubka kalyaha ee macmalka ah, dareeraha xuubka saliimaynta biyaha badda iyo dareeraha kale ee ay soo saaraan warshadaha dawooyinka.
