Waa maxay faraqa u dhexeeya walxaha PP iyo polyesterka?

1. falanqaynta alaabta

PP maro-dhoobo ah: Fiber-ka loo isticmaalo wax-soo-saarka dharka aan-dhogorta lahayn waa polypropylene, kaas oo ah fiber synthetic ah oo laga helo polymerization of propylene.

Dharka polyester-ka ah ee aan-xidhka lahayn: Fiber-ka loo isticmaalo wax-soo-saarka dharka aan-xidhka lahayn waa fiber polyester-ka, kaas oo ah fiber synthetic ah oo laga helo duubista polyester-ka oo laga soo ururiyay dibasic acid organic iyo diol.

2. Cufnaanta kala duwan

PP dhar aan tol lahayn: Cufnaantiisu waa 0.91g/cm3, taas oo ah noocyada ugu fudud ee fiilooyinka kiimikada caadiga ah.

Dharka polyester-ka ah ee aan-xidhka lahayn: Marka polyesterku uu yahay gebi ahaanba amorphous, cufnaantiisu waa 1.333g/cm3.

3. caabbinta iftiinka kala duwan

PP maro-dhoobo ah: caabbinta iftiinka liidata, caabbinta goynta, gabowga fudud iyo khasaaro jajaban.

Dharka polyester-ka ah ee aan-dhogorta lahayn: iska caabbinta iftiinka wanaagsan, kaliya 60% lumis xoog ah ka dib 600h iftiinka qorraxda.

4. Guryaha kulaylka kala duwan

PP dhar aan tol lahayn: xasilloonida kulaylka liidata, oo aan u adkaysan karin feereeynta.

Dharka polyester-ka ah: iska caabbinta kulaylka wanaagsan, barta dhalaalaysa ee ku saabsan 255 ℃, iyo qaab xasiloon oo hoos yimaada tiro balaadhan oo ah shuruudaha isticmaalka dhamaadka.

5, iska caabin alkali oo kala duwan

Polypropylene dhar aan tol lahayn: Polypropylene waxay leedahay iska caabin kiimikaad oo wanaagsan, ka sokow soodhada caustic, polypropylene waxay leedahay iska caabin alkali oo wanaagsan.

Maro polyester-ka ah: Polyester-ku waxa uu leeyahay iska caabin xun oo alkali ah, kaas oo dhaawici kara faybarka marka uu la falgalo alkali urursan heerkulka qolka oo uu ku milo alkali heerkul sare.Kaliya way xasilloon tahay in lagu milo alkali ama alkali daciifka ah heerkulka hooseeya.
