iimveliso

i-polypropylene yelaphu elingalukwanga,
PP Resin, PP resin kushishino BOPP, PP resin kushishino lokubumba Isitofu,

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.

Kule veki i-polypropylene downstream yokuthenga injongo yehlile, iifektri zineeholide, ulwakhiwo jikelele luphantsi kakhulu.Lilonke, ishishini lasekhaya le-polypropylene ezantsi (kubandakanya ukunithwa kweplastiki, ukugoba isitofu, i-BOPP, i-PP engalukwanga ilaphu) izinga lokusebenza lilonke lehle nge-14.7% ukuya kwi-36.2%.Isantya sokunitha iplastiki sehle nge-9.5% ukuya kuma-34%;Isantya sokubumba isitofu sehle nge-17% ukuya kuma-32%;I-BOPP iqala yawa yi-2.8% ukuya kwi-60.1%;Iziqalo ezingalukwanga zehle nge-29.8% ukuya kwi-18.5%.

Ngokwembono yecala lemfuno, izinga lokusebenza kweshishini lokunitha ngeplastiki kule veki lisezantsi kakhulu kuneveki ephelileyo, lihle nge-13% unyaka nonyaka.Ekupheleni konyaka, uninzi lwamashishini angenile kule holide, imeko ye-odolo yamashishini yehla kakhulu, amanye amashishini aodola ngokukhawuleza, umdla wamashishini wokuzalisa izinto ezikrwada uhlile, ikakhulu ukwetyisa uluhlu lwemveliso egqityiweyo, umoya wokurhweba jikelele kwimarike. yayibanda;Ngokubhekiselele kwishishini le-BOPP, iintsuku zoku-odola zamashishini esampula kule veki ziyi-7.89% xa kuthelekiswa nexesha elidlulileyo.Njengoko imfuno iyonke ye-BOPP ayilunganga njengakwiminyaka edlulileyo, ezantsi kunye nabarhwebi baseholideyini kwangaphambili, kwaye umoya wokurhweba jikelele wemarike uya usiba lula njengoko uMnyhadala weNtwasahlobo usondela.Uninzi lwamashishini e-membrane abeke iiodolo kwangaphambili, kwaye uninzi lwamashishini e-membrane asebenza ngokuqhelekileyo kwinqanaba langoku, kunye nokulandelwa okulinganiselweyo kwee-odolo ezintsha.Ishishini lokubumba i-injection liqala ukuhla ngokukhawuleza, iifektri zineeholide, ishishini liqala ukuhla ngokucacileyo;Umzi-mveliso welaphu ongalukiweyo phakathi evekini ukuqalisa ulungiso olubalulekileyo, iintsuku zoku-odola zale veki xa kuthelekiswa neveki ephelileyo -ientsuku ezi-3.5, iiodolo ezisezantsi zabonisa ukuhla.I-PP yamashishini amashishini angalukiweyo angenile kwiholide, iintengiselwano zeshishini elitsha zincinci kakhulu.Ngokubanzi, echatshazelwa yiholide yoMthendeleko we-Spring, ukwakhiwa kwe-downstream ngokubanzi kwawa ngokukhawuleza, ngaphambi kokuba iholide iphakanyiswe yikamva, ukusebenza kwempahla kuphuculwe, ukuxhasa i-polypropylene market trend nokomelele.

Ekuhambeni kwexesha, ukubonelela nge-polypropylene kunye nemfuno yomdlalo osisiseko kusabonakala.Emva kweholide, kukho ukulindela ukugcinwa kwempahla kwiimarike.Ukongeza, kwisicwangciso somthamo omtsha wemveliso, i-Guangdong Petrochemical kulindeleke ukuba ikhulule izinto ngexesha leeholide, kwaye uxinzelelo lokubonelela ngeemarike luyanda kakhulu.Ngokwemfuno, ishedyuli esezantsi yokuqalisa umsebenzi emva kweholide iyona nto ixhalabisayo kwiimarike.Kucetyiswa ukuba abaqhubi banike ingqwalasela enkulu kwishedyuli esezantsi yokuqalisa umsebenzi.
