Sharaxaad Gaaban:

Tetrabutylurea (TBU) caadi ahaan waa dareere huruud ah oo aan midab lahayn. Waxa ay leedahay mad-madow badan waxaana lagu yaqaanaa ur lagu garto, taas oo lagu tilmaami karo mid khafiif ah ama macaan yar. TBU waxay ku milmi kartaa dareerayaasha organic waxayna leedahay isbeddel yar.

Tetrabutylurea cas 4559-86-8 waxaa loo isticmaali karaa in lagu diyaariyo balaastikada iyo xasiliyayaasha loogu talagalay sunta cayayaanka, daawooyinka, dheeha, iyo balaastikada.

Codsiga

Tetrabutylurea (TBU)waa iskudhis inta badan loo isticmaalo sida dareere iyo reagent ee codsiyada kala duwan ee kiimikada. Macluumaad faahfaahsan oo dheeraad ah, fadlan tixraac soo socda:
 
1. Miraha ku jira isku-dhafka organic:1,1,3,3-Tetrabutylurea waxaa badanaa loo isticmaalaa sida dareeraha falcelinta organic, gaar ahaan marka la isku daro xeryahooda organic kala duwan. Awooddeeda ay ku kala diri karto noocyo kala duwan oo polar ah iyo walxaha aan dabaylaha ahayn ayaa ka dhigaya mid aad waxtar ugu leh goobaha shaybaarka.
 
2. Soo saarista iyo kala saarida:TETRA-N-BUTYLUREA waxaa loo isticmaali karaa hababka soo saarista dareeraha- dareeraha ah si loo kala saaro xeryahooda ku salaysan milmahooda. Waxay si gaar ah wax ku ool u tahay soo saarista ions birta qaarkood iyo xeryahooda organic ee isku dhafka ah.
 
3. Reagents ee falcelinta kiimikada:N,N,N',N'-Tetra-n-butylurea waxaa loo isticmaali karaa fal-celin kiimiko ah oo kala duwan, oo ay ku jiraan falcelinta ku lug leh beddelka nucleophilic iyo isbeddellada kale ee dabiiciga ah.
 
4. Xamuul qaade:Nidaamyada kicinta qaarkood, TBU waxaa loo isticmaali karaa sidii dhexdhexaadiyaha qaade si kor loogu qaado milmaheeda iyo falcelinta isku dhafka falcelinta.
 
5. Codsiyada Cilmi-baarista:N,N,N',N'-TETRA-N-BUTYLUREA waxaa loo isticmaalaa deegaanka cilmi baarista, gaar ahaan cilmi baarista ku lug leh saamaynta xalinta, dareeraha ionic iyo qaybaha kale ee jirka iyo kiimikada.
 
6. Kiimikada Polymer:N,N,N',N'-tetrabutyl-;tetrabutyl-ure waxa kale oo loo isticmaali karaa kimistariga polymer waxaana loo isticmaali karaa dareere ama wax lagu daro isku-dhafka polymer.

Sidee loo kaydiyaa Tetrabutylurea?

Tetrabutylurea (TBU) waa in si sax ah loo kaydiyaa si loo ilaaliyo xasiloonida loogana hortago khatar kasta oo iman karta. Waa kuwan qaar ka mid ah tilmaamaha kaydinta tetrabutylurea:
 
1. Konteenar:Ku kaydi urea tetrabutyl weel xiran si aad uga hortagto faddaraynta iyo uumiga. Weelku waa inuu ka samaysan yahay maaddooyin ku habboon dareerayaasha organic, sida dhalooyinka ama balaastikada qaarkood.
 
2. Heerkulka:Ku kaydi TBU meel qabow oo qalalan oo ka fog ilayska qoraxda iyo kulaylka tooska ah. Sida habboon, waa in lagu kaydiyaa heerkulka qolka, laakiin xaaladaha kaydinta gaarka ah waxay ku xirnaan karaan talooyinka soo-saaraha.
 
3. Hawo-qaadista:Hubi in meelaha wax lagu kaydiyo ay hawo fiican leeyihiin si loo yareeyo ururinta uumiga laga yaabo in la sii daayo.
 
4. Ka sooc walxaha aan isqaban karin:Ku kaydi urea tetrabutyl meel ka fog oksaydhiyeyaasha xooggan, aashitada iyo walxaha kale ee aan is qaadan karin si aad uga hortagto fal-celin khatar ah.
 
5. Summada:Si cad ugu calaamadee weelasha magaca kiimikada, xoogga saarista, macluumaadka khatarta, iyo taariikhda la helo. Tani waxay gacan ka geysaneysaa aqoonsiga walxaha waxayna hubisaa in si badbaado leh loo maareeyo.
 
6. Taxaddar Badbaadada:Raac dhammaan xeerarka iyo xeerarka badbaadada kaydinta kiimikada ee khuseeya, oo ay ku jiraan kuwa ay bixiso machadkaaga ama xeerarka deegaanka.
 
7. Tuur:Haddii Tetrabutyl Urea loo baahan yahay in la tuuro, fadlan u hoggaansan shuruucda deegaanka ee ku saabsan qashin-qubka khatarta ah.
 
Had iyo jeer tixraac xaashida xogta badbaadada alaabta (MSDS) ee Tetrabutyl Urea si aad u hesho talooyinka kaydinta iyo maaraynta gaarka ah.

Digniinaha inta lagu jiro gaadiidka ku saabsan Tetrabutylurea?

Marka la qaadayo urea tetrabutyl, taxaddarrada qaarkood waa in la sameeyaa si loo hubiyo badbaadada iyo u hoggaansanaanta xeerarka. Kuwa soo socda waa qaar ka mid ah tixgelinnada muhiimka ah ee ay tahay in la tixgeliyo inta lagu jiro gaadiidka:
 
1. U Hogaansanaanta Xeerarka:Hubi in shixnadku u hoggaansamo xeerarka maxalliga ah, qaranka iyo kuwa caalamiga ah ee ku saabsan qaadista walxaha halista ah. Hubi haddii urea tetrabutyl loo kala saaro walxo khatar ah raacna tilmaamaha ku habboon.
 
2. Baakadaha:Isticmaal baakad ku habboon oo ku habboon urea tetrabutyl. Weelku waa inuu noqdaa mid aan dareerin oo ka samaysan shay u adkaysan kara sifooyinka kiimikaad ee TBU. Hubi in baakadu ay xoog badan tahay si looga hortago burbur inta lagu jiro gaadiidka.
 
3. Summada:Si cad ugu calaamadee baakooyinka magaca kiimikada, astaanta khatarta, iyo wixii macluumaad badbaado ah oo khuseeya. Tan waxa ku jira hab-raaca hab-raaca iyo macluumaadka xidhiidhka degdegga ah.
 
4. Xakamaynta heerkulka:Haddii loo baahdo, ku qaado Tetrabutylurea xaaladaha heerkulka lagu xakameeyo si looga hortago xaalufka ama isbeddelka guryaha. Ka fogow soo-gaadhista heerkul aad u daran.
 
5. Ka fogow walxaha aan isqaban karin:Hubi in Tetrabutylurea aan lala soo rarin agabka aan ku habboonayn sida oksaydhiyeyaasha ama asiidhyada si looga hortago falcelin kasta oo iman kara.
 
6. Qalabka Ilaalinta Shakhsi ahaaneed (PPE):Shaqaalaha ku lug leh gaadiidka waa inay xidhaan PPE ku habboon, sida galoofyada, muraayadaha indhaha, iyo dharka ilaalinta si loo yareeyo soo-gaadhista haddii ay dhacdo daadasho ama dillaac.
 
7. Hababka Gurmadka:Samee habab degdeg ah oo lagula tacaalayo daadinta ama shilalka inta lagu jiro gaadiidka. Tan waxaa ku jira diyaarinta xirmooyinka daadinta iyo saadka gargaarka degdegga ah.
