PP resin ee baakadaha,
caafimaad, fiilada indhaha, PP resin loo isticmaalo baabuurta,

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.

Codsiga

Xidhmada

Bac 25kg ah, 16MT hal 20fcl oo aan lahayn pallet ama 26-28MT hal 40HQ oo aan lahayn palette ama 700kg jumbo bac, 26-28MT hal 40HQ oo aan lahayn pallet.

Polypropylene waa mid aan sun ahayn, ur lahayn, caano aan dhadhamin oo cad cad polymer crystallization, waa mid ka mid ah noocyada ugu fudud ee dhammaan balaastikada hadda, qaabaynta wanaagsan, dhalaalka dusha sare, caabbinta kulaylka, caabbinta daxalka, alaabada la heli karo jeermiska uumiga ayaa ah faa'iidooyinka muuqda ee polypropylene .

Maaddada ugu muhiimsan ee polypropylene waa propylene, taas oo inta badan laga sameeyo naphtha, methanol iyo propane.

Marka loo eego tirakoobka, dhamaadka 2018, waxaa jiray in ka badan 160 shirkadood oo wax soo saarka propylene ee Shiinaha, oo leh awood wax soo saar sanadle ah oo ku saabsan 32.3 milyan oo tan iyo wax soo saarka sanadlaha ah ee ku saabsan 27.1 milyan oo tan, kobaca sanadlaha ah ee ku saabsan 2.26 %.

Qiimaha propylene ma saameynayo oo kaliya qiimaha saliidda cayriin, methanol, propane, laakiin sidoo kale sahayda suuqa iyo xiriirka baahida.

Noocan ah walxo ceeriin kiimiko ah oo si weyn loogu isticmaalo tolida caagga ah, baakadaha, baabuurta,caafimaad, fiilada indhahaiyo dhinacyada kale, ee horumarinta warshadaha cusub, cusboonaysiinta, waxaa jiri doona shuruudo cusub.

Iyada oo horumarka joogtada ah ee dhaqaalaheena, warshadaha wax soo saarka caaggu waxay soo bandhigaysaa isbeddel cusub oo baahida "shaqayn", "fudud" iyo "micro-samaynta", taas oo kaxaysa koritaanka xasilloon ee baahida loo qabo qaabaynta irbado khafiif ah-derbiga, saamaynta sare copolymerization. , fiber iyo alaabada kale ee polypropylene.
