Polypropylene Copolymer Sinopec Qilu,
PP resin ee xadhkaha, PP resin ee suumanka shandad tan, PP resin ee bacaha tolmada leh,

Polypropylene waa resin synthetic ah oo lagu sameeyay polymerization of propylene (CH3-CH=CH2) oo leh H2 oo ah wax ka beddelka miisaanka unugyada.Waxaa jira saddex stereomers ee PP - isotactic, atactic iyo syndiotactic.PP kuma jiraan kooxo polar waxayna leedahay sifooyin koronto oo aad u fiican.Heerka nuugista biyaha ayaa ka yar 0.01%.PP waa polymer semi-crystal ah oo leh xasilooni kiimiko oo wanaagsan.Way deggan tahay kiimikooyinka badankooda marka laga reebo oksaydhiyeyaasha xooggan.Aashitada inorganic, alkali iyo xalalka milixdu wax saameyn ah kuma laha PP.PP waxay leedahay caabbinta kulaylka wanaagsan iyo cufnaanta hoose.Barta dhalaalkeedu waa qiyaastii 165 ℃.Waxay leedahay xoog xajin sare iyo qallafsanaanta dusha sare iyo iska caabin dildilaac deegaan oo wanaagsan.Waxay u adkeysan kartaa 120 ℃ si joogto ah.

Sinopec waa soosaarka ugu weyn ee PP ee Shiinaha, Awoodeeda PP waxay ka dhigan tahay 45% awoodda guud ee dalka.Shirkaddu waxay hadda haysaa 29 PP oo geeddi-socodka joogtada ah (oo ay ku jiraan kuwa la dhisayo).Farsamooyinka ay adeegsadaan cutubyadaan waxaa ka mid ah habka Mitsui Chemical's HYPOL, habka wejiga gaaska Amoco, habka Basell's Spheripol iyo Spherizone iyo habka wajiga gaaska Novolen.Iyada oo awooddeeda cilmi-baadhiseed ee xooggan, Sinopec waxay si madaxbannaan u samaysay hab-socodka jiilka labaad ee wax-soo-saarka PP.

Tilmaamaha PP

1. Cufnaanta qaraabada waa yar tahay, kaliya 0.89-0.91, taas oo ah mid ka mid ah noocyada ugu fudud ee balaastikada.

Guryaha farsamada 2.good, marka lagu daro iska caabbinta saameynta, sifooyinka kale ee farsamada ayaa ka fiican polyetylen, wax-qabadka wax-qabadka ayaa fiican.

3.Waxay leedahay iska caabin kulayl sare leh iyo heerkulka isticmaalka joogtada ah wuxuu gaari karaa 110-120 °C.

4. sifooyinka kiimikaad ee wanaagsan, ku dhawaad ​​ma laha nuugista biyaha, oo kuma falceliso kiimikooyinka intooda badan.

5.dharka waa saafi, aan sun ahayn.

6.xakamaynta korontada ayaa wanaagsan.

Tixraaca sida caadiga ah loo isticmaalo ee darajada PP

Codsiga

Xidhmada

PP-ga ay bixiso shirkadeena waa darajada silig-sawirka, darajada copolymer, iyo darajada silig sawirida ayaa si weyn loogu isticmaalaa warshadaha caaga ah, bacaha tolmada leh, suumanka bac tan, xadhko, iwm, waxaana sidoo kale loo isticmaali karaa duritaanka PP. warshadaha, qaybaha, koobabka, iwm.
Polypropylene Copolymer waxaa si weyn loogu isticmaalaa wax soo saarka warshadaha, sida dashboards, gudaha baabuurta, bampers baabuurta, gudaha iyo dibadda qaybaha mashiinada dharka, weelasha baytari iyo haamaha biyaha.Waxa kale oo loo isticmaali karaa in lagu sameeyo alaabta guriga sida alaabta guriga, alaabta carruurtu ku ciyaarto, shandadadaha iyo weelasha baakadaha kala duwan.
