Iichips zepolymer zePolymer ezifana ne-PET ziyi-hygroscopic, okuthetha ukuba zifunxa ukufuma kwiatmosfera engqongileyo.Ukufuma okuninzi kwiichips kunokubangela iingxaki ngexesha lokubumba kunye ne-extrusion.Xa iplastiki ifudunyezwa, amanzi ekuwo i-hydrolyzes PET, enciphisa amandla kunye nomgangatho wayo.Oku kuthetha ukuba umswakama obuninzi ngokusemandleni kufuneka ususwe kwi-resin ngaphambi kokucubungula i-PET kumatshini wokubumba.Ngaphantsi kweemeko ze-atmospheric, i-resin ingaba ne-0.6% ngobunzima bamanzi.
Iipellet zePET zomiswa phambi kokuba zicutshungulwe
Izitshixo zokhuni zilayishwa kwihopha, emva koko umoya oshushu owomileyo oneqondo lobushushu lombethe omalunga ne-50°C umpontshelwa emazantsi ehopper kwaye uqukuqelele phezulu phezu kweepeliti, ususa nabuphi na ubumanzi obusendleleni.Owona moya ushushu kakhulu ushiya umphezulu wehopper kwaye udlule kwi-aftercooler kuqala, njengoko umoya obandayo ususa ukufuma ngokulula kunomoya oshushu.Umoya obandayo, omanzi emva koko udlula kwibhedi ye-desiccant.Ekugqibeleni, umoya obandayo obandayo oshiya umbhede we-desiccant uphinde uhlaziywe kwi-heater yenkqubo kwaye ubuyiselwe ngenkqubo efanayo kwi-loop evaliweyo.Isiqulatho sokufuma seetshiphusi kufuneka sibe ngaphantsi kwe 30 ppm phambi kokuba kusetyenzwe.Xa i-PET ishushu, nawaphi na amanzi akhoyo aya kukhupha ngokukhawuleza i-hydrolyze kwi-polymer, ukunciphisa ubunzima bemolekyuli kwaye bonakalise iimpawu zayo ezibonakalayo.
Umlinganiselo we-Intanethi kunye nokujonga indawo
Kukho iindlela ezimbini zokulinganisa ukufuma ngexesha lokumisa: umlinganiselo we-intanethi kunye nokujonga indawo.
① umlinganiselo we-intanethi
Izomisi zomntu ngamnye zisoloko zijongwa ngokuqhubekayo ukuqinisekisa ukuba unikezelo lomoya kwi-PET lungcono kunomlinganiselo ochaziweyo wombethe wama-50 ° C kwindawo yombethe ukuqinisekisa ukuba izinto ze-chip zomiswe ngokufanelekileyo.Apho kufuneka imilinganiselo echanekileyo enolungelelwaniso lwangaphakathi oluzenzekelayo, iHT-608 isivamvo sombetheinokufakwa kufuphi ne-inlet ye-drying hopper, kunye nobukhulu bayo obuncinci kunye nokukhanya okulula kwenza kube lula ukuyifaka kwimibhobho okanye kwiindawo eziqinileyo ukujonga ukuvuza kwindlela yomoya yokomisa.Ukuchaneka okuphezulu ± 0.2 ° C (5-60 ° C Td), xa kuthelekiswa nomgangatho wemveliso ephuma kumazwe angaphandle, efikelelekayo, yindlela engabizi kakhulu.
② Jonga indawo kwaye ulungelelanise
Ukuhlolwa rhoqo kunye noHengkoI-HK-J8A102 ephathwayo yobushushu obulinganisiweyo kunye nemitha yokufumainokubonelela ngesiqinisekiso esingabizi kakhulu somgangatho wemveliso.Kulula ukuyisebenzisa, ngaxeshanye ukulinganisa ubushushu, ukufuma, indawo yombethe, ibhalbhu emanzi kunye nezinye iinkcukacha.Phendula ngokukhawuleza kwiindawo zombethe ezisemgangathweni ongaphantsi kwama-50℃.
Uluhlu lomlinganiselo weqondo lombethe lobushushu kunye nemitha yokufuma lu: -50℃-60℃, kunye nescreen esikhulu seLCD sikulungele ukufunda nokufunda. Idatha yokulinganisa ibalwa kanye kwi-10 milliseconds, kwaye isantya sokuphendula sinovakalelo kwaye umlinganiselo uchanekileyo.
