Iindaba

I-PET (i-Polythylene Terephthalate) ye-polymoplastic esetyenziswe ngokubanzi kwizicelo ezahlukeneyo, njengokupakisha, ii-tict, kunye nobunjineli. Isilwanyana sasekhaya sineemephu ezigqwesileyo, i-thermal, kunye ne-optical, kwaye zinokuphinda zisetyenziselwe ukuphinda ziphinde zisebenze kwaye ziphinde zancitshiswe iimveliso ezintsha. Nangona kunjalo, isilwanyana sasekhaya sikwayindawo ye-hygroscopic, okuthetha ukuba ifunxa umswakama kwindalo esingqongileyo, kwaye oku kunokuchaphazela umgangatho wakhe kunye nokusebenza kwayo. Ukufuma kwesilwanyana sasekhaya kunokubangela i-hydrolysis, eyimpendulo yekhemikhali eqhekeza imixokelelwane yePolymer kwaye inciphise i-viscofity (iv) yezinto. IV ngumlinganiso wobunzima bemolekyuli kunye nenqanaba le-polymerization yesilwanyana, kwaye luphawu olubalulekileyo lwamandla, lukhuni, kunye nokufihlakeleyo kwento. Ke ngoko, kubalulekile ukuba owomileyo kwaye ubeke isilwanyana ngaphambi kokuba uphumezwe, ukususa umswakama kwaye uthintele ilahleko ye-IV.

I-crystal ye-crystal ye-crystal eyomileyoNgaba i-novel kunye netekhnoloji esebenzayo esebenzisa i-infrared (ir) ukukhanya kome kwaye ikhuphe i-flakes kwinyathelo elinye, ngaphambi kokuba ukondle inyathelo lokuqhubela phambili. Ukukhanya kwe-IR yindlela ye-elektromagnetic radiation enamaza phakathi kwe-0.7 ne-1000 ne-1000 yemicrons, kwaye inokufakwa kwiimolekyuli zasekhaya, ezenza ukuba zivelise ubushushu. Ukukhanya kwe-IR kunokungena kwizikhonkwane ze-PET kwaye ubuyise ngaphakathi, kubangele ukomisa okukhawulezileyo nangokufanelekileyo kuneendlela eziqhelekileyo, ezinje ngomoya oshushu okanye owomayo oshushu.

I-increation ye-incraud ye-crystal ineengenelo ezininzi kwiindlela zemveli ezomayo kunye nekristali, ezinje:

Ukuncitshiswa kwexesha elomileyo kunye nekristali

• Ukucutha amandla amandla: I-IR ukukhanya inokusoma kwaye ikhuphe iiflestali ze-PET AMANZI NGE-0.08 kWh / kg, i-0.4 kg / kg / kg efunwa ngeendlela eziqhelekileyo.

• Ukucuthwa komxholo womswakama: I-IR ukukhanya inokusoma kwaye ikhuphe iiflestali ze-PET ziyokugqibela yokufuma okungaphantsi kwe-50 i-PPM, xa kuthelekiswa ne-100 ukuya kwi-200 ye-PPM efezekiswe ngeendlela eziqhelekileyo.

• Ukunciphisa ilahleko ye-IV: I-IR ukukhanya inokusoma kwaye ikhuphe iiflestali ze-PET nge-0.05, ithelekiswa ne-0,2.2 iv ilahleko ezibangelwa ziindlela eziqhelekileyo.

Ukunyusa ububanzi be-bulk: i-IR inokwandisa ukuxinana kwezilwanyana ezi-10 ukuya kwi-20%, kuthelekiswa noxinano lwantlandlolo kunye nokuphuma komntu ophumeleleyo.

• Ukuphuculwa kwemveliso yemveliso: I-IR ukukhanya inokusoma kwaye ikhuphe i-flakes ye-PET ngaphandle kokubangela ukuba ityheli, ukonakaliswa, okanye ukungcolisa, okuphucula ukubonakala kweemveliso zokugqibela.

Ngezi zinto ziluncedo, i-crystal ye-lettal eyomileyo inokuphucula ukusebenza kunye nomgangatho wokukhutshelwa kwesilwanyana, kwaye unokuhlangabezana neemfuno zezicelo zenqanaba lokutya.

Inkqubo ye-interstal ye-crystal eyomileyo inokwahlulwa ibe ngamanyathelo amathathu aphambili: ukondla, ukomisa kwaye kucekeceke.

Ukondla

Inyathelo lokuqala le-crystal ye-crystal eyomileyo yolonwabo. Kweli nyathelo, i-pekeuki ye-Pet, enokuba yintombi okanye iphinde isebenze, yondliwe kwi-IR yomisa i-IR screw Super okanye i-hopper. Iiflekis ze-PET zinokuba nomxholo wokufuma wokuqala ukuya kuthi ga kwi-10,000 ukuya kwi-13,000 i-PPM, kuxhomekeke kumthombo kunye neemeko zogcino. Ireyithi yokondla kunye nokuchaneka kwezinto ezibalulekileyo ezichaphazela intsebenzo eyomileyo kunye nekristali kunye nomgangatho wemveliso.

Ukomisa kwaye kunyanzelisa

Inyathelo lesibini le-incread ye-crystal yomisa izilonda ze-motor yomisa kwaye icelela. Kweli nyathelo, ifleki yase-PET ityhilwe kukukhanya i-IR ngaphakathi kwedrum ejikelezayo, enesitayile esijikelezayo kunye neepaddles kwi-paddles yayo. Isibane se-IR sikhutshwa yibhanki yesikhululo se-IR esikhrithi, esikumbindi we-Drum. Isibane se-IR sinamaza e-1 ukuya kwii-microns ezi-2, ezithathwe kwi-virct spectrum ye-Pet kunye namanzi, kwaye inokungena ukuya kuthi ga kwi-5 mm kwizikhephe. Ukukhanya kwe-IR kukhanyisa izilwanyana zasekhaya ngaphakathi, kubangela iimolekyuli zamanzi ziphuma kwaye iimolekyuli zezilwanyana zishukumise kwaye zilungelelanise kwisakhiwo se-crystalline. Umphunga wamanzi ususwe ngumjelo womoya ophumeleleyo, oqukuqela kwidrum kwaye ethwala umswakama kude. Ijelo leSpiral kunye neePaddles zidlulisela iiflethi ze-PET ecaleni kwe-axis, iqinisekisa iyunifomu kunye nokuvezwa kwe-ir. Inkqubo eyomileyo necrystalling ithatha malunga nemizuzu engama-20, kwaye iphumela kwi-rouncination yokugqibela engaphantsi kwe-50 ye-PPM kunye nelahleko encinci ye-0.05. Inkqubo eyomileyo necrystalling ikwandisa ubuninzi besilwanyana sasekhaya nge-10 ukuya kwi-20%, kwaye kuthintela ukungqukuva kunye nokukhwaza kwento.

Ukuphuma

Inyathelo lesithathu nelokugqibela le-crystal ye-crystal eyomileyo ye-right iphela. Kweli nyathelo, i-Plakes eyomileyo neziseto yezilwanyana ezondliwe kulowo uphendulwe, nto leyo inyibilikayo, ihlaba impahla, kwaye injengee-pellets, iifibles, okanye iifilimu, okanye iifilimu. Umntu ophumeleleyo unokuba sisikrweqe esinye okanye i-screw-screw yesikhafu, kuxhomekeka kwinkcazo yemveliso kunye noongezelelo olusetyenzisiweyo. Umntu ophumeleleyo unokuxhotyiswa nge-vacuum vie, enokususa nawuphi na umswakazana okanye ii-volaties ezinyibilikayo. Inkqubo yokuphucula iphembelelwa sisikhafu, ubume besikati, ubushushu be-barrel, i-gefie yejometry, kwaye unyibilikise i-ramology. Inkqubo yokuphucula kufuneka ilungiselelwe ukufezekisa isiphene esigudileyo nesizinzileyo, ngaphandle kweziphene, njengokunyibilikisa iqhekeza, i-Die lingazinzi. Inkqubo yokuphucula ikwazi ukulandelwa yinkqubo yonyango, njengokupholisa, ukusika, okanye ukuqokelela, kuxhomekeka kuhlobo lwemveliso kunye nezixhobo ezisezantsi.

Ukuqukumbela

I-intertal ye-crystal ye-crystal ye-crystal yomisa inoveli kunye netekhnoloji ye-ir esebenzisa ukukhanya kwe-IR kwindawo eyomileyo kunye ne-crystalize inyathelo elinye, ngaphambi kokuba libe selokuqhubela phambili. Itekhnoloji inokuphucula ukusebenza kunye nomgangatho wokukhutshelwa kwesilwanyana, ngokunciphisa ixesha elomileyo nelikristali, ukusetyenziswa kwamandla, umxholo wokufuma, kunye nokwandisa ubuninzi be-bulk kunye nomgangatho wemveliso. Itekhnoloji ikwazi ukuhlangabezana neemfuno zezicelo zenqanaba lokutya, ngokugcina i-IV kwaye ikhusele ukugqobhoza kunye nokudaniswa kwesilwanyana sasekhaya. Le teknoloji inokuba negalelo kuzinzo kunye noqoqosho lwesetyhula, ngokwenza kwakhona ukuphinda kusetyenziswe kwakhona kunye nokusebenzisa kwakhona izilwanyana zemveliso entsha.
