I-Ultem® (Igama le-PARY LE-PEI) yi-amorphos yeplastiki elula kwi-thermoform okanye ibhondi kunye nenye yenye iqondo elingaziwayo le-Thermoplastic. I-Ultem® Pei inesakhiwo esingafakwanga yimolekyuli, uluhlu olubanzi kakhulu, indawo yokunyibilika ye-218 ° C, i-V-0 yedangatye yedangatye, kunye nokukwazi ukugcina ubushushu obuphakathi. I-peirable eqhubekayo ivelisa i-fuimus ezincinci, idangatye liyithole kwaye lixhathise ngemichiza, lenza ukuba ibe yinto efanelekileyo kwishishini le-aerospace kunye neebhodi zesekethe.
1. Kubandakanya iziteshi zokutshintsha kobushushu
Ngexesha lenkqubo yokuxhuzula, umenzi wakho uya kuchitha ixesha elininzi ukupholisa iinxalenye zakho ngaphambi kokudiliza nokufudumeza ubumba bakho ngaphambi kwenaliti. Ezi nkqubo zinokukhawuleziswa ngokubandakanya iziteshishishishishishishishishishishishishishishiyisela i-SPREY KWI-GARD yakho yoMnxeba. Ezi teshi kufuneka zibhengeze i-cavity nganye kwinani elifanayo lokufudumeza okanye ukulimala ngaxeshanye. Oku kuyakuvumela umvelisi wakho ukuba akhule ngokukhawuleza kwaye aphakamise okanye anciphise ubushushu bokwamba.
2. Sebenzisa izikhonkwane ze-thermal
Ukuba akunakwenzeka ukubandakanya iziteshi zokuhambisa ubushushu kwiinxalenye ezithile zombuso ngenxa yokwandiswa okanye ukuqulunqwa, izikhonkwane ze-thermal zingasetyenziswa. Ngokuphathelele ukuqhubela phambili kwe-purmas ephezulu, ezi zikhonkwane zinokutshintshela ngokukhawuleza ubushushu kuzo naziphi na iindawo ezingafikelelekiyo ezifikeleleke kwi-SURDWELS yokuhambisa ubushushu. Izikhonkwane ezishushu ziya kwenza iqondo lobushushu bangaphakathi be-mold ngaphandle kokuphazamisa uxinzelelo olupholeyo.
Izikhonkwane ze-thermal ziquka amanzi atywinwe ngaphakathi kwi-cylinder. Njengoko ulwelo lufunxa ubushushu bubushushu obuvela kwi-onbul, ikhutshiwe kwaye iyaziqhawula njengoko ikhupha ubushushu kwifowuni ekupholileyo. Ngokuhambisa ubushushu phantse amatye ali-10 amakhulu kunoPhando lwe-Worper kunye ne-Walvar Alfal Alfal, izikhonkwane ezishushu zezona ndlela zibalaseleyo xa unemilongo entsokongileyo. Qiniseka nje ukuba uphephe naziphi na izithuba zomoya phakathi kwezikhonkwane ezishushu kunye nokubumba, okanye ukuzalisa ngetywina elinenkani.
I-3. Khetha izinto ezingalunganga zobumba
Izinto zokubumba zichaphazela imveliso yokugqibela kunye noyilo lokutsala. Kuya kufuneka ufumane iqondo lobushushu eliphezulu elineqondo elibonisa ibhalansi phakathi kokuziqhelanisa, iindleko, kwaye unxibe ukunganyangeki. Emva kwayo yonke loo nto, ufuna ukubumba ukuba kugcinwe iintshukumo ezininzi, kodwa awufuni ukuba uthathe ixesha elininzi okanye imali yokwenza. Ukuba ucwangcisa kwimveliso ephezulu yevolyuli, cinga usebenzisa intsimbi enkulu enamadoda anjenge-H-13, S-7, okanye i-р20. Ukuba wenza iiprototypes, i-aluminium yinto esebenzayo yexabiso lendleko.
Isakhiwo esikhethekileyo sePlaysigering Plain_focus kwii-on-fight ii-onnes zibunjwe
Xa kuthelekiswa nezinto zentsimbi zemveli, iiplasitiki zobunjineli okhethekileyo zinokuzinza kakuhle, itekhnoloji yayo yokulungisa, ayinakutshintsha ngokukhawuleza ukubonakala kwemveliso yemveliso, kodwa nokuhlangabezana nemveliso yemveliso yemveliso amalungu kunye neemfuno zenkangeleko.
IPlastiki ePhezulu yoBunjineli obukhethekileyo njenge: I-Peek, i-PPS, PPS, i-PU, i-PUS, njl., Ukuxhathisa ubushushu obuphezulu, amandla aphezulu kunye nezinye iimpawu kunye nezinye iimpawu.
I-Polyteether Ether Ketone (Peek) ye-Inating ye-Inating kunye nezicelo zayo:
Ngenxa yokuba ukuchasana nobushushu obuphezulu lobushushu, ukunyangwa okungagungqiyo, iipropathi ezintle zoomatshini, kokokuqala kwasetyenziswa kwicandelo lenqwelomoya, endaweni yezixhobo zentsimbi ukwenza inqwelomoya yangaphakathi. Emva kokuba isetyenziswe njengokuthengisa iimoto kunye namanye amalungu: izihlalo ze-valve, iivalves, amakhonkco episton; Iipropathi ezigqwesileyo zombane zivumela i-peki inokusetyenziswa ukuze zithande umphathi we-wafer wan. kunye nokuzinza okuhle kwamachiza kunye nokunganyangeki kwamachiza kunokusetyenziswa kwicandelo lezonyango.
Ngokwesiqhelo, i-Peek yokubumba i-300 ~ 340 ℃, uyilo loyilo, ungasebenzisa ukukhanya okuphezulu kunye nokuposa kunye nezinye iindlela, inaliti yomatshini wokubumba Ukulungiswa kumyinge wengcinezelo kunye nesantya sokuqinisekisa ukuba ubungakanani kunye nomgangatho wemveliso yokufezekisa iimfuno.
I-polyphenyne sulfiide (PPS) ye-Inating ye-Inating ye-Inating kunye nezicelo zayo:
I-PPs inesibindi esihle sokuchasana nobushushu, ukubuyisa ilangatye, ukuntywila kombane, ukunyibilika kunye nezinye iimpawu zemodyuli zombane, iindawo zemodyuli zolawulo lwe-elektroniki, iinxalenye zemodyuli zetekisi. Ukuphendula imeko yemoto yemoto, amakhulu eenxalenye ezisetyenziswayo kwiindawo ezisebenza ngaphandle kokusebenza kwiindawo ezingaphandle kwezithuthi zangaphakathi.
Ukuze ufumane inkangeleko elungileyo yemveliso, inaliti ye-PPS ye-PPS kufuneka ibe nenaliti ephakamileyo, ukwenzela ukuba igcinwe imitha yezinzileyo, kucetyiswa ukuba uxinzelelo lwangasemva lubekwe kwi-2 ~ 5MPA, i-10NPA, Ulawulo olungqongqo lweqondo lokushisa kunye nexesha, ukunqanda ifuthe eliphezulu kakhulu okanye eliphantsi kakhulu kwifuthe elibi kwintsebenzo yezinto zePPS.
