iimveliso

Zeziphi iimveliso ezenziwe kwiPP?,
I-PP yeeCaps kunye noValo, PP resin for ingca Artificial, I-PP resin yokuPakisha ukutya,

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
