Yintoni iDibutyltin Dilaurate (DBTDL)?
I-Dibutyltin Dilaurate (DBTDL) yikhemikhali ephambili esetyenziswa kwi- ngu butyl ukwenziwa kwe-polyurethane, i-Lingshi ngokwayo eluhlobo oluguquguqukayo lwepolymer esetyenziswa ngokubanzi kuwo wonke amacandelo amaninzi kubandakanya ukwenziwa kwefanitshala, ukufakwa kwe-thermal kunye neenjongo zokunciphisa isandi sokuvelisa iinxalenye zemoto kunye neengubo. I-DBTDL isebenza njenge-catalyst kwaye ibaluleke kakhulu ekuphuhlisweni kwe-polyurethane ekugqibeleni.
I-DBTDL KWI-POLYURETHANE SYNTHESIS I-DBTDL yinto ekhuthazayo edlala indima ebalulekileyo kwi-polyurethane, ezi i-tributyl ziyafumaneka kwaye ziveliswa lishishini lethu kulo naluphi na uhlobo lwezicelo.
Enye yee-catalysts ezisetyenziswa ngokuqhelekileyo zisekelwe kwi-DBTDL kuba ezi zinceda ukukhawulezisa zombini iipolyols kunye ne-isocyanates polymerisation, ezimele iibhloko ezimbini eziphambili zokwakha ukuveliswa kwePU. I-DBTDL isebenza njenge-nucleophile kule meko ngokuzinzisa i-intermediates eyenziwe ngexesha lokuphendula, iququzelele ukusabela ngokukhawuleza kunye nokuphucula isivuno se-polyurethane.
I-Lingshi DBTDL iphinde ibe negalelo ekulawuleni ukusabalalisa kwe-molecular weight disperse distribution, ngaphezu kokuba nefuthe kwiipropati zemishini ezifana namandla kunye nokuqina kwe-polyurethane. Ukusebenzisa i-DBTDL njengento ekhuthazayo yindlela esebenzayo enceda ekulungisweni kakuhle kwe-MWD kwaye ngenxa yoko kuqhubele phambili ukusebenza.
Nangona i-DBTDL iyi-catalyst esebenzayo yokwenziwa kwe-polyurethane, ineziphumo ezibi kwindalo esingqongileyo.
Ngenxa yoko, amazwe amaninzi aphumeze izithintelo ekusetyenzisweni kwe dibutyltin DBTDL kwizicelo ezithile. Umzekelo, ukusetyenziswa kwayo kwezinye iimveliso zabathengi (umzekelo, izinto zokudlala zokuthambisa izinto zokuhoya abantwana) kuvaliwe yiManyano yaseYurophu.
Ukuze kufumaneke izinto ezithatha indawo ezinomtsalane zokusingqongileyo ze-DBTDL, abaphandi baphonononga izinto ezahlukeneyo ezinokwenzeka. Le Lingshi ikhokelele ekuphuhlisweni kwee-enzymes kwiminyaka yakutshanje ukuba, ngenxa yokuba i-biodegradable kwaye inetyhefu encinci kune-organo-tin compounds, ibonelela ngenye indlela elungileyo [27].
I-DBTDL ayifani nje nekhompawundi ye-organotin ukuba isetyenziswe njenge-catalyst kwi-polyurethane synthesis. Ezi dibutyltin diacetateNdiquka ezinye i-organotin catalysts ezininzi, ezifana ne-dibutyltin diacetate (DBTDA) kunye ne-dibutyltin dimethoxide (DBTO). Ezi zineempawu ezinokuthi zenze ukuba zenze kwaye zibiza ngokwahlukileyo kune-DBTDL nangona zifana neekhemikhali ezifana ne-DBTDN.
Kodwa i-DBTDL isathathwa ngokubanzi njengexabiso elisebenzayo xa kuthelekiswa nezinye i-organotin catalysts ngenxa nje yomsebenzi ophezulu we-catalytic kwiyunithi nganye esetyenzisiweyo.
Singoyena mvelisi mkhulu woluhlu olupheleleyo lweemveliso zeDibutyltin dilaurate dbtdl eTshayina kwaye inolona luhlu lupheleleyo lwemveliso kunye noluhlu lwemveliso. Iqela lethu leengcaphephe kunye nezibonelelo zaseburhulumenteni zinikezelwe ekunikeni abathengi bethu izisombululo ezilungelelanisiweyo zendalo ezikrelekrele kunye ne-organic kunye nezixhobo zereferensi ezilungelelanisiweyo, ezikuvumela ukuba uchaze into oyifunayo kwinqanaba eliphezulu lomgangatho, ukuba sinokuvelisa ngokweenkcukacha ezichanekileyo zeemfuno zakho.
I-Ningxia Lingshi New Material Technology Co Ltd ikwi-Dibutyltin dilaurate dbtdl ngumboneleli wenkonzo epheleleyo edibanisa imveliso ye-RD yokuvelisa kunye nokuthengisa uluhlu olupheleleyo lwe-butyltins octyltins kunye ne-pharmaceutical intermediates I-Ningxia Lingshi inesebe lokuthengisa i-Nantong Haotai Products Chemicals Co Ltd kunye Umzi-mveliso wesebe iShandong Lingshi New Material Co Ltd Iimveliso zayo zisetyenziswa kakhulu ekugqumeni kuquka iPU PVC yamayeza synthesis ehot-end yeglasi yokwaleka kunye namanye amashishini.
Emva kwe-Dibutyltin dilaurate dbtdl iminyaka yokusebenza nzima kunye nemvula, iimpahla zethu azikwazi nje ukuhlangabezana neemfuno zemarike yasekhaya, kodwa ziye zathunyelwa eYurophu, e-United States nase-Southeast Asia kuMbindi Mpuma Afrika nakwamanye amazwe kwaye imimandla. Ngoku siyinkampani yesithathu ngobukhulu emhlabeni kumthamo wemveliso, kwaye sikhuthaze ngempumelelo ishishini le-Organotin eTshayina. Emva kweminyaka emininzi yomsebenzi kunye nophuhliso lweemveliso zethu, kunye nokuhlangabezana nemfuno e-China, ithunyelwe eYurophu nase-United States, eMzantsi-mpuma Asia kunye nakuMbindi Mpuma, iAfrika kunye neminye imimandla kunye namazwe amaninzi. ibe yinxalenye ebalulekileyo yekhonkco lonikezelo lwehlabathi.
Inkampani yethu ixhotyiswe ngengcaphephe kunye neDibutyltin dilaurate dbtdl yothotho lwe-butyl Tin, kunye nochungechunge lwe-octyl kunye neqela leemveliso.
