imikhiqizo

Uhlobo oluphansi lwe-carboxyl i-antimony yamahhala ye-LC eyi-semi dull

incazelo emfushane:

Izici
Yenziwe nge-titanium ehlanganisiwe eluhlaza futhi ephumelelayo i-DH hyti Catalysis (Lcej).I-lcej ayinazo izinsimbi ezisindayo.
Inkomba yekhwalithi iqhathaniswa namaflakhi avamile e-PET akhanyayo aqukethe i-antimony, ngaphandle kokuthi i-antimony ayitholakali futhi iqembu le-carboxyl letheminali liphansi.Kungandisa i-viscosity.
I-carboxyl PET flakes/amafayibha/amafilimu nezinye izinto zinokumelana okuqinile ne-hydrolysis ne-alkali.
Ayikho i-antimony yensimbi esindayo etholakele emikhiqizweni/emikhiqizweni, akukho ukufuduka kwe-antimony, kuphephile futhi kunempilo.
Ingakwazi ukuxazulula inkinga yokuqukethwe kwe-antimoni okweqile ekuphrintiwe kwendwangu kanye nokudaya amanzi angcolile emikhiqizo yezilwane ezifuywayo eziqukethe i-antimoni futhi ihlangabezane nezidingo zokukhiqiza okuhlanzekile.


Imininingwane Yomkhiqizo

Omaka bomkhiqizo

Isicelo

Ingenziwa ngokuqondile / ifilimu eyenziwe, noma icutshungulwe ngemva kokuyibamba;Ingasetshenziselwa ulwelwesi lwamapuleti angemuva, i-geotextile, indwangu ye-super fiber, njll.

Izakhiwo Ezivamile

I-DH hyti ikhwalithi ephansi ye-carboxyl antimony yamahhala ye-LC polyester chip yekhwalithi yomkhiqizo

Inombolo yomkhiqizo Izinto Iyunithi Inkomba yekhwalithi (L-17)Imiphumela yokuhlolwa  

Indlela yokuhlola / Ejwayelekile

1 I-viscosity yangaphakathi dL/g 0.675± 0.025 0.672 I-GB/T 14190-2017
2 Iphoyinti lokuncibilika 260±3 260
3 Okuqukethwe kwe-terminal carboxyl i-mol/t 7±3 9.1
4 I-Chromaticity  

B inani

  4±2 4.78
L inani   ≥80 81
5 Umswakama (ingxenyana yobuningi) % ≤0.5 0
6 ≥ 10 µ m Izinhlayiya ezihlanganisiwe /mg ≤6.0 0
7 Okuqukethwe kwe-Diethylene glycol (ingxenye enkulu) % 1.20±0.30 1.02
8 Okuqukethwe kwe-ayoni mg/kg ≤2 1
9 Impushana mg/kg ≤100 1
10 Ucezu olungavamile (ingxenye enkulu) % ≤0.6 0
11 Okuqukethwe kwe-Antimony ppm ≤10 ND Ngokusho kwe-US EPAmethod3052:1996, i-ICP-OES yasetshenziswa

Inani elimaphakathi lokuqukethwe kweqembu lokugcina le-carboxyl lizonqunywa phakathi kwebanga elingu-≤ 28mol / T ngezingxoxo phakathi komphakeli nomthengi.Uma sekunqunyiwe, ngeke kushintshwe ngokungafanele.

Inani elimaphakathi yenani le-chromaticity b lizonqunywa izinhlangothi zombili ngokubonisana phakathi kwebanga elingu-≤ 10. Uma selinqunyiwe, ngeke lishintshwe ngokuthanda kwakhe.

Inani elimaphakathi lokuqukethwe kwe-diethylene glycol lizonqunywa yizinhlangothi zombili ngokubonisana ngaphakathi kwebanga elingu-≤1.5%.Uma sekunqunyiwe, ngeke kushintshwe ngokuthanda kwakho.

Inkomba yokuqukethwe kwe-Antimony: Umkhawulo wokutholwa wale ndlela ngu-10ppm, futhi i-Nd ayitholakali.
