Antimony free super eqaqambileyo L-uhlobo
Ingasetyenziselwa ukwenza i-polyester staple fibers kunye neefilaments.Yimathiriyeli ekrwada esisiseko eluhlaza yamashishini epolyester ukwenza iifiber kunye neemveliso ezinxulumeneyo.
Isalathiso somgangatho we-DH hyti i-antimony yasimahla eqaqambileyo ye-L-uhlobo lwe-PET chip
| Inombolo yesiriyeli | Izinto | Iyunithi | Isalathisi somgangatho | (L-17) Iziphumo zovavanyo | Indlela yokuvavanya / uMgangatho | |

Ixabiso eliphakathi lomxholo weqela le-carboxyl liya kumiselwa phakathi koluhlu lwe-≤ 28mol / T ngothethwano phakathi komthengisi kunye nomthengi.Xa sele imisiwe, ayisayi kutshintshwa ngokuzenzekelayo.
Ixabiso eliphakathi le-chromaticity b ixabiso liya kugqitywa ngamaqela omabini ngokubonisana phakathi koluhlu lwe-≤ 10. Xa sele imisiwe, ayiyi kutshintshwa ngokuthanda.
Ixabiso eliphakathi lomxholo we-diethylene glycol liya kugqitywa ngokuvunyelwana phakathi koluhlu lwe-≤1.5%.Xa sele imisiwe, ayisayi kutshintshwa ngokuthanda kwayo.
Isalathisi somxholo we-Antimony.Umda wokufumanisa le ndlela yi-10ppm, akukho kufunyanwa kweNd.
1) Ithini imiqathango yentlawulo?
Ikakhulu i-T / T, i-L / C kunye ne-D / P, imimiselo yokuhlawula ngokwenene nceda ukhangele nathi xa ubeka ii-odolo.
2)Ixesha elingakanani ukuhanjiswa kwakho emva kokufaka iodolo?
Siza kulungiselela ukuhanjiswa ngokukhawuleza ngokweshedyuli yesebe lemveliso kunye nemeko.Ngenxa yeshedyuli yokuthumela okanye ezinye izinto, nceda uqhagamshelane nathi xa ufaka ii-odolo.
