I-PET yomisa njani ukulinganisa ukufuma?

Iitshiphusi zepolymer zePolymer ezinje ngePET zinehygroscopic kwaye 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. Kuthetha ukususa umswakama obuninzi ngokusemandleni kwi-resin ngaphambi kokucubungula i-PET kumatshini wokubumba. Ngaphantsi kweemeko ze-atmospheric, i-resin ingaba ne-0.6% ngobunzima bamanzi.

Ke i-PET yomisa njani ukulinganisa ukufuma?

Apha sidwelisa iiNgcebiso eZimbini oFumana ukuKhathalela xa uyenza i-PET yokomisa ukulinganisa ukufuma.

Iipellet zePET zomiswa phambi kokuba zicutshungulwe

Izitshixo zokhuni zilayishwa kwi-hopper, emva koko umoya oshushu, owomileyo kunye nobushushu bombethe obumalunga ne-50 ° C umpontshelwa emazantsi ehopper, kwaye uqukuqela phezulu phezu kweepellets, ususa naluphi na ukufuma endleleni. Umoya oshushu ushiya umphezulu wehopper kwaye udlule kwi-after cooler kuqala, njengoko umoya obandayo ususa ukufuma ngokulula kunomoya oshushu. Umoya obandayo, omanzi emva koko udlula kwibhedi ye-desiccant. Ekugqibeleni, umoya obandayo, owomileyo 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 imilinganiselo echanekileyo enolungelelwaniso oluzenzekelayo lwangaphakathi lufuneka, unokufaka iHT-608 isivamvo sombethekufuphi ne-inlet ye-hopper yokomisa, kunye nobukhulu bayo obuncinci kunye nekhaphukhaphu yenza 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 yokufumac ephathwayo elinganisiweyo ubushushu imitha kunye nokufuma kunokubonelela ngexabiso elisebenzayo isiqinisekiso 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 yi -50℃-60℃, kwaye iscreen esikhulu seLCD sikulungele ukufunda nokufunda. Idatha yokulinganisa ibalwa kanye nge-10 milliseconds, kwaye isantya sokuphendula sinovakalelo, kwaye umlinganiselo uchanekile.

Usenemibuzo kwaye uthanda ukwazi ngakumbi ngeNkcukacha zokuJonga ukufuma phantsi kweeMeko zeMozulu eziMandundu, Nceda uzive ukhululekile ukuQhagamshelana nathi ngoku.
