iimveliso

I-PP resin ye-PP yokuqhelaniswa ne-polypropylen,
I-polypropylene resin ukuvelisa ifilimu ye-OPP,

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

Ngeenguqu ezingaphezu kwe-100 ezahlukeneyo iPolypropylene Film yenye yeefilimu ezisetyenziswa kakhulu kwihlabathi.Isicelo esiqhelekileyo se-polypropylene sinjenge-oriented polypropylene (OPP).Lo mboniso bhanyabhanya uneempawu ezigqwesileyo zobungqina bokufuma okwenza oku kukhulu ekusebenziseni ii-inki eziqhelekileyo ezivelisa iziphumo ezicacileyo zoshicilelo.Namhlanje ifilimu yokupakisha eguquguqukayo ehamba phambili okwesibini kuphela kwi-polyethylene ephantsi yobuninzi bomthamo.

(OPP) Ifilimu yePolypropylene eQinisekileyo
Ipolymer ye-thermoplastic esetyenziswa kwiintlobo ngeentlobo zezicelo ukusuka kwipakethi ukuya kwiikhaphethi.Ukusetyenziswa okuphambili kwefilimu ye-OPP kukupakishwa kokutya ngenxa yokomelela okuhle, ukucaca okuphezulu, iipropathi ezifanelekileyo zesithintelo kunye neendleko eziphantsi xa kuthelekiswa ne-cellophane.Kuphantse kuyo yonke indawo yobomi bakho bemihla ngemihla.I-Polypropylene ixhathisa kakhulu ukudinwa.Ke ihenjisi yohlobo lweplastiki inokuvulwa kwaye ivalwe ngamaxesha angama-1000 ngaphandle kokudinwa.Uninzi lweepakethe ze-flip-top zinale nto.Inkqubo yokunyibilika kwepolypropylene iphunyezwa nge-extrusion kunye nokubumba.Indlela eqhelekileyo yokubumba esetyenziswayo kukubumba inaliti.Obunye ubuchule kukubumba ukuvuthela kunye nenaliti eyolula iblow folding.Ngokukwazi ukulungelelanisa amabakala athile kunye neempawu ezithile ze-molekyuli ngexesha lokuvelisa kwenza inani elikhulu lokusetyenziswa kokuphela kokusetyenziswa.Umzekelo wale nto iya kuba kukusetyenziswa kwe-antistatic additive ukunceda i-polypropylene surface ukumelana nokungcola kunye nothuli.
