iimveliso

I-PP resin yokupakisha,
ezonyango, intambo yefiber optical, PP resin esetyenziselwa imoto,

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

Kwingxowa ye-25kg, i-16MT kwi-20fcl enye ngaphandle kwe-pallet okanye i-26-28MT kwi-40HQ enye ngaphandle kwe-pallet okanye i-700kg jumbo bag, i-26-28MT kwi-40HQ enye ngaphandle kwe-pallet.

Ipolypropylene ayinatyhefu, ayinavumba, ayinancasa yobisi olumhlophe oluphezulu lwecrystallization polymer, yenye yezona ntlobo zikhaphukhaphu kuzo zonke iiplastiki okwangoku, ukumila kakuhle, iimveliso ezibengezela kumphezulu, ukumelana nobushushu, ukuxhathisa ukubola, iimveliso ezifumanekayo zokubulala iintsholongwane ngomphunga ziinzuzo ezibalaseleyo zepolypropylene. .

Eyona nto iphambili ye-polypropylene yipropylene, eyenziwa ngokukodwa kwi-naphtha, methanol kunye nepropane.

Ngokwezibalo, ekupheleni kuka-2018, kwakukho amashishini okuvelisa ipropylene angaphezu kwe-160 e-China, kunye nomthamo wemveliso yonyaka malunga ne-32.3 yezigidi zeetoni kunye nemveliso yonyaka malunga ne-27.1 yezigidi zeetoni, ukukhula konyaka-ngonyaka malunga ne-2.26 %.

Ixabiso lepropylene alichatshazelwa kuphela ngexabiso leoli ekrwada, i-methanol, ipropane, kodwa kunye nokuthengiswa kweemarike kunye nobudlelwane bemfuno.

Olu hlobo lwemathiriyeli ekrwada esetyenziswa kakhulu kwiplastiki yokuluka, ukupakisha, iimoto,ezonyango, intambo yefiber opticalkunye neminye imimandla, kuphuhliso olutsha lwemizi-mveliso, ukuphuculwa, kuya kubakho iimfuno ezintsha.

Ngophuhliso oluqhubekayo loqoqosho lwethu, ishishini lokulungisa iplastiki libonisa indlela entsha yemfuno "yokusebenza", "ikhaphukhaphu" kunye "ne-micro-molding", eqhuba ukukhula okuzinzileyo kwemfuno yokubumba inaliti eludongeni, impembelelo ephezulu ye-copolymerization. , ifayibha kunye nezinye iimveliso zepolypropylene.
