Acid Terephthalic saafi ah: Walaxda Kala Duwan ee Codsiyada Badan leh

Aashitada terephthalic ee saafiga ah (PTA) waa walax kala duwan oo leh codsiyo warshadeed oo badan.Waa crystalline adag oo cad oo ugu horrayn loo isticmaalo soo saarista polyetylen terephthalate (PET), polymer-waxqabad sare leh oo leh codsiyo kala duwan.

 

Acid Terephthalic saafi ahwax soo saarka PET

Aashitada terephthalic ee saafiga ah waa alaabta ceeriin ee muhiimka ah ee soo saarista terephthalate polyetylen.PET waa polymer xoog badan, khafiif ah, oo dib loo warshadayn karo oo si weyn looga isticmaalo warshado kala duwan oo ay ku jiraan baakadaha, dunta, roogagga, iyo baabuurta.Waxa kale oo si caadi ah looga helaa alaabta macaamiisha sida dhalooyinka, weelasha, iyo baakadaha cuntada.

Aashitada terephthalic ee saafiga ah ayaa loo beddelaa dimethyl terephthalate (DMT) inta lagu jiro habka wax soo saarka, kaas oo markaa la polymerized si loo abuuro PET.Isticmaalka PTA ee wax soo saarka PET waxay ku siinaysaa beddel tayo sare leh oo waara oo ka duwan polymers kale.Waa dib loo warshadayn karaa oo dib loo isticmaali karaa, iyadoo yaraynaysa qashinka iyo saamaynta deegaanka.

 

Codsiyada kale ee Acid Terephthalic Saafi ah

Marka lagu daro isticmaalka wax soo saarka PET, terephthalic acid saafi ah ayaa leh codsiyada kale ee warshadaha.Waxaa loo isticmaalaa soo saarista polybutylene adipate (PBA), polymer biodegradable kaas oo ku habboon baakadaha iyo filimada beeraha.Aashitada terephthalic ee saafiga ah ayaa sidoo kale loo isticmaalaa soo saarista polyurethane (PU), kuwaas oo si weyn loogu isticmaalo sida elastomers, sealants, iyo dahaarka.

 

Muuqaalka Acid Terephthalic Saafi ah

Baahida loo qabo aashitada terephthalic saafiga ah ayaa la filayaa inay koraan sanadaha soo socda sababtoo ah isticmaalka sii kordhaya ee PET ee warshadaha kala duwan.Iyadoo loo riixayo sii waaridda iyo wacyigelinta deegaanka, dib-u-warshadaynta iyo dib-u-isticmaalka PET waxay sii wadi doontaa baahida loo qabo asiidhka terephthalic saafi ah.

Intaa waxaa dheer, horumarinta polymers-ka cusub ee biodegradable iyadoo la adeegsanayo terephthalic acid saafi ah waxay siin kartaa fursado korriin oo dheeri ah suuqa.Isticmaalka balaadhinta polyurethane ee dhismaha, baabuurta, iyo warshadaha alaabta guryaha ayaa sidoo kale gacan ka geysan doona baahida loo qabo terephthalic acid saafi ah.

 

Caqabadaha Soo saarista Asiidhka Terephthalic ee Saafi ah

In kasta oo ay sii kordhayso baahida loo qabo aashitada terephthalic saafi ah, habka wax soo saarku wuxuu noqon karaa mid adag.Maaddadu aad bay u daxalaysaa waxayna u baahan tahay qalab gaar ah oo si badbaado leh oo waxtar leh loogu maareeyo.Kharashka wax soo saarka ee sarreeya iyo xeerarka deegaanka ee adag ayaa sidoo kale caqabad ku noqon kara gelitaanka shirkadaha qaarkood.

 

Gabagabada Acid Terephthalic Saafi ah

Aashitada terephthalic ee saafiga ah waa walax isku dhafan oo leh codsiyo badan oo warshadeed, oo ugu horreyn loo isticmaalo soo saarista polymers-ka waxqabadka sare leh sida PET.Isticmaalka sii kordheysa ee PET ee warshadaha kala duwan iyo riixitaanka dhinaca sii jirista, baahida loo qabo terephthalic acid saafi ah ayaa la filayaa inay koraan sanadaha soo socda.Si kastaba ha ahaatee, habka wax soo saarku wuxuu noqon karaa mid adag sababtoo ah kharashka badan, xeerarka adag, iyo welwelka badbaadada.
