Terephthalic acid (PTA) Walxaha ceeriin ee Furaha ah ee Polyester-ka

Sharaxaad faahfaahsan

Acid Terephthalic caadi ahaan waxay u muuqataa sida cad, budo crystalline leh milmayn hoose oo biyaha ah iyo xasilloonida kulaylka sare. PTA-fasalka warshadaha waxaa lagu soo saaraa oksaydhka firfircoonida ee para-xylene, oo ay ku xigto hababka nadiifinta ee hubinaya heerarka wasakhda aadka u hooseeya, gaar ahaan 4-CBA (4-carboxybenzaldehyde).

Halbeegyada tayada muhiimka ah waxaa ka mid ah nadiifinta, qoyaanka qoyaanka, qaybinta cabbirka walxaha, iyo xakamaynta wasakhda, kuwaas oo dhammaantood si toos ah u saameeya midabka polymer, miisaanka kelli, iyo waxtarka farsamaynta ee wax soo saarka polyester-ka hoose.

Astaamaha Muhiimka ah

• Nadiifin kiimiko oo sarreeya iyo falcelin deggan

• Degenaansho kuleyl iyo kiimiko oo heer sare ah

• Waxyaalaha wasakhda yar (gaar ahaan 4-CBA)

• Ku habboon hababka polymerization joogto ah

• Tayada joogtada ah ee fiber, filim, iyo wax soo saarka resin

Codsiyada

• Polyester Fiber
  Alaabada ceeriin ee aasaasiga ah ee fiilooyinka PET ee loo isticmaalo dunta, kuwa aan dunta ka samaysan, iyo dunnada warshadaha.

• Xabagta PET & Dhalooyinka
  Loo isticmaalo soo saarista resins PET ee dhalooyinka cabitaanka, weelasha cuntada, iyo alaabta baakadaha.

• Filimada Polyester-ka
  Codsaday soo saarista filimada PET ee dahaarka korantada, baakadaha, iyo isticmaalka warshadaha.

• Caagagga Injineerinka
  Loo isticmaalo polyester-ka wax laga beddelay iyo resins takhasus leh oo leh xoog farsamo oo sarreeya iyo iska caabbinta kulaylka.

• Dahaarka & Xabagta
  Waxay u adeegtaa sida walxo cayriin oo loogu talagalay daaha-ku-saleysan polyester-ka, resins, iyo nidaamyada xabagta.

Kaydinta

Si loo ilaaliyo tayada badeecada loogana hortago faddaraynta, Terephthalic acid waa in lagu kaydiyaa xaaladaha la xakameeyey:

• Ku kaydi bakhaar qallalan, qabow, oo hawo fiican leh

• Baakadaha si adag u xir si aad uga hortagto qaadashada qoyaanka

• Ka fogow soo-gaadhista huurka iyo iftiinka qorraxda tooska ah

• Heerkulka kaydinta lagu taliyay: xaaladaha deegaanka

• Isticmaal bacaha safan, bacaha waaweyn, ama silo badan

• Kahortagga wasakheynta boodhka, saliidda, iyo walxaha shisheeye
