Iplastiki yePolypropylene (PP)
* I-Polypropylene yi-semi crystalline thermoplastic. Inokumelana okuphezulu, iipropati ezinamandla zoomatshini, kunye nokumelana nezinyibilikisi ezahlukeneyo ze-organic kunye nokugqwala kwe-acid-base.
* Ukumelana neekhemikhali okugqwesileyo Amanqanaba akhuselekileyo okutya ayafumaneka.
* Iimveliso zeplastiki zePP ezenziwe ngokwezifiso okanye iinxalenye
I-Polypropylene, efinyeziweyo njenge-PP, yi-polymer eyenziwe nge-propylene nge-polymerization reaction. Yinto emhlophe, efana ne-wax enembonakalo ecacileyo nekhaphukhaphu. Ifomyula yekhemikhali (C3H6)n, ubuninzi be-0.89 ~ 0.91g/cm3, iqondo lokunyibilika elinokutsha le-164 ~ 170 ° C, ithambile kwi-155 ° C okanye ngaphezulu, kusetyenziswa ubushushu obuphakathi kwe--30 ~ 140 ° C.
Ayikwazi ukumelana nokugqwala yi-asidi, i-alkali, ulwelo lwetyuwa kunye neentlobo ezininzi zezinyibilikisi ze-organic ezingaphantsi kwama-80℃, kwaye inokubola phantsi kobushushu obuphezulu kunye ne-oxidation. Isetyenziswa kwiintlobo ngeentlobo zezicelo, kubandakanya ukupakishwa kwabathengi, iindawo zeplastiki kwishishini leemoto kunye nempahla.
Yintoni onokuyenza ngePP Plastiki?
I-Polypropylene yeyona nto ilula yeplastiki xa ithelekiswa nobunzima bayo. Inkangeleko yayo ayinambala kwaye ayibonakali, kwaye njengeplastiki yodidi lokutya, isetyenziswa kakhulu ekupakisheni ukutya, njengeebhokisi zeStyrofoam, iikomityi zeplastiki zePP, njalo njalo. I-Polypropylene inokwahlulwa ibe ziindidi ezintlanu eziphambili ngokwezicelo zayo eziphambili: ukubumba i-PP injection, umzobo wePP, i-PP fiber, ifilimu yePP, kunye nombhobho wePP.

Iimpawu zePolypropylene (PP)
Ukumelana neekhemikhali: Iziseko kunye nee-asidi ezinyibilikisiweyo azihlangani ne-PP, nto leyo eyenza ukuba ibe sisitya esifanelekileyo salo manzi (umz. izinto zokucoca, iimveliso zoncedo lokuqala, njl.njl.).
Ukuthamba kunye nokuqina: I-PP iyathamba ngaphakathi koluhlu oluthile lokuphambuka kwaye idlula kwi-plastic deformation kwasekuqaleni kwenkqubo yokuthamba ngaphandle kokuqhekeka, ngoko ke idla ngokuthathwa njengesixhobo "esiqinileyo".
Ukumelana nokudinwa: I-PP igcina imo yayo emva kokujijeka nokugoba kakhulu. Le propati ixabiseke kakhulu ekwenzeni iihinges ezishukumayo.
Ubushushu: Izinto zePP zinokumelana okuphezulu kombane kwaye zizinto zokukhusela.
Ukudluliselwa kwemifanekiso: Ingenziwa ngemibala ecacileyo, kodwa idla ngokwenziwa ngemibala engacacanga ngokwendalo enomlinganiselo othile wokudluliselwa kwemifanekiso. Ukuba kufuneka ukudluliselwa kwemifanekiso okuphezulu, kufuneka kukhethwe i-acrylic okanye i-PC.
Zenziwa njani izinto zePP?
Njengezinye iiplastiki, iPolypropylene (PP) iqala njenge "nxalenye" (iqela elikhaphukhaphu) ukusuka ekunyibilikiseni amafutha e-hydrocarbon kwaye idibana nezinye ii-catalysts ukuvelisa iiplastiki ngokusebenzisa i-polymerization okanye i-polycondensation reactions.

I-Polypropylene (PP) – Inkqubo yokuvelisa:
Umgubo ofunyenweyo ekugqibeleni uthunyelwa kwiisilo zomgubo uze uguqulwe ube ziipellets eziquka uluhlu olupheleleyo lwe
izongezo ezisasazeke kakuhle.
Ukuphinda kusetyenziswe iplastiki yePolypropylene (PP) kunye nokukhuselwa kokusingqongileyo
Xa i-polypropylene iphinda isetyenziswe, inciphisa ukusetyenziswa kwezixhobo ezinqongopheleyo ezifana neoyile kunye negesi yepropane. Malunga ne-8% yeoyile yehlabathi (malunga ne-400 yezigidi zeetoni) isetyenziswa kwiindlela zemveli zokuvelisa iiplastiki, apho i-4% yazo isetyenziswa "njengempahla yokutya" kwaye enye i-4% isetyenziswa kwimveliso. Ukuba iiplastiki beziveliswa kwiiplastiki eziphinda zasetyenziswa, ukusetyenziswa kwamandla bekuya kuncitshiswa nge-88%. Ngoko ke, ukuphinda kusetyenziswe iiplastiki ze-polypropylene kunobuhlobo nokusingqongileyo!
