Synthetic Intambo ekrwada imathiriyeli-Polypropylene,
I-Polypropylene yeNtambo yePlastiki, Imveliso yentambo imathiriyeli ekrwada,

I-Polypropylene yi-resin yokwenziwa eyenziwe nge-polymerization ye-propylene (CH3—CH = CH2) kunye ne-H2 njenge-molecular weight modifier.Kukho ii-stereomers ezintathu zePP - isotactic, atactic kunye ne-sydiotactic.I-PP ayinamaqela e-polar kwaye ineempawu ezintle zokugquma umbane.Izinga lokufunxa kwawo amanzi lingaphantsi kwe-0.01%.I-PP yi-polymer ye-semi-crystalline ene-chemical stability efanelekileyo.Izinzile kwiikhemikhali ezininzi ngaphandle kwee-oxidizers ezinamandla.I-asidi ye-Inorganic, i-alkali kunye netyuwa izisombululo ziphantse zingabi nampembelelo eyonakalisayo kwi-PP.I-PP inokumelana nobushushu obuhle kunye noxinzelelo oluphantsi.Indawo yayo yokunyibilika ikwi-165℃.Inamandla aphezulu okuqina kunye nokuqina komphezulu kunye noxinzelelo olulungileyo lokusingqongileyo ukumelana nokuqhekeka.Iyakwazi ukumelana ne-120℃ ngokuqhubekayo.

ISinopec ngoyena mvelisi mkhulu wePP eTshayina, umthamo wayo wePP ubalelwa kwi-45% yomthamo welizwe.Inkampani okwangoku inezityalo ezingama-29 zePP ngokwenkqubo eqhubekayo (kubandakanywa nezo ziphantsi kolwakhiwo).Ubuchwepheshe obusetyenziswa zezi yunithi ziquka inkqubo ye-HYPOL yeMitsui Chemical, inkqubo yegesi ye-Amoco, inkqubo ye-Basell's Spheripol kunye neSpherizone kunye nenkqubo yesigaba segesi ye-Novolen.Ngobuchule bayo obunamandla bophando lwezenzululwazi, iSinopec iye yaphuhlisa ngokuzimeleyo isizukulwana sesibini loopprocess yemveliso yePP.

Iimpawu zePP

I-1.Ubuninzi obusondeleyo buncinci, kuphela i-0.89-0.91, enye yeentlobo ezilula kakhulu kwiiplastiki.

I-2.impawu ezintle zoomatshini, ngaphezu kokuchasana kwempembelelo, ezinye iimpawu zomatshini zingcono kune-polyethylene, ukubunjwa kokusebenza kokubumba kulungile.

I-3.Inokumelana nokushisa okuphezulu kunye nobushushu bokusetyenziswa okuqhubekayo bunokufikelela kwi-110-120 °C.

I-4.izinto ezintle zeekhemikhali, phantse akukho manzi, kwaye ayisebenzi kunye neekhemikhali ezininzi.

5.ukuthungwa kucocekile, akukho tyhefu.

6.i-electrical insulation ilungile.

Isalathiso esisetyenziswa ngokuqhelekileyo kwibakala lePP

Isicelo

Iphakheji

I-Polypropylene mhlawumbi yeyona nto ixhaphakileyo efumaneka kwiintambo ezisetyenziswa kwintsimi yaselwandle.Esinye isizathu kukuba ilula kunamanzi, yaye ngaloo ndlela iyadada.
Intambo yePlastiki yePolypropylene ikwabizwa ngokuba yi "Polypropene Rope" okanye "PP Plastic Rope".Yenziwe ngoku kulandelayo: I-Monomer Propylene kunye ne-polymerization yokukhula eyipolymer ye-thermoplastic, eqinile kwaye iqinile esetyenziswa kwizicelo ezahlukeneyo.Ifomula yemichiza yePolypropylene yi (C3H6)n.
