Yintoni i-PTFE?
I-PTFE eyaziwa njenge "inkosi yeplastiki", yipolymer yepolymer eyenziwe nge-tetrafluoroethylene njenge-monomer.Yafunyanwa nguGqirha Roy Plunkett ngo-1938.I-pan non-stick iqatywe i-PTFE yokwambathisa kumphezulu wepani, ukuze ukutya kungabambeleli ezantsi kwepani, ebonisa ukumelana nobushushu obuphezulu be-PTFE kunye neempawu eziphezulu zokuthambisa.Kule mihla, izixhobo ze-PTFE zomgubo zenziwa kwiimveliso zeemilo ezahlukeneyo, ezifana neetyhubhu ze-PTFE, ifilimu ebhityile ye-PTFE, imivalo ye-PTFE, kunye neepleyiti ze-PTFE, ezisetyenziswa kwiinkalo ezahlukeneyo.Okulandelayo, sixoxa ngokusetyenziswa kweetyhubhu ze-PTFE kwizixhobo zomshicileli we-3D.
Ngaba i-PTFE Inetyhefu?
Isihloko sokuba ingaba i-PTFE iyityhefu iyaphikisana kwaye i-PTFE ayinabungozi.
Kodwa xa i-PFOA (i-Perfluorooctanoic Acid) yongezwa ngaphambili kwi-PTFE izithako, i-toxin yakhululwa xa isetyenziswe kumaqondo aphezulu.I-PFOA inzima ukuthotywa kokusingqongileyo, kwaye inokungena ebantwini nakwezinye izinto eziphilayo ngezinto eziphathekayo, umoya kunye namanzi, kwaye ngokuhamba kwexesha kunokukhokelela ekunciphiseni izinga lokuzala kunye nezinye izifo ze-immune system.Kodwa ngoku i-PFOA ivaliwe ngabasemagunyeni ukuba bayongeze kwizithako ze-PTFE.Zonke iingxelo zethu zovavanyo lwempahla ekrwada nazo zibonisa ukuba akukho candelo lePFOA.
Kutheni abashicileli be-3D besebenzisa iityhubhu ze-PTFE?
Ngophuhliso olukhawulezayo lweThe Times, umshicileli we-3D yitekhnoloji ekhawulezayo yokwenza, eyaziwa ngokuba yimveliso yokongeza.Yinkqubo yokudibanisa okanye yokunyanga izinto eziphantsi kolawulo lwekhompyuter ukuvelisa izinto ezinomacala amathathu, ngokuqhelekileyo kusetyenziswa iimolekyuli zolwelo okanye amasuntswana omgubo ukuhlangana kunye kwaye ekugqibeleni wakhe izinto umaleko.Okwangoku, iteknoloji yokubumba i-3D yoshicilelo iqukwa ngokubanzi: indlela yokunyibilika kokunyibilika, njengokusetyenziswa kwe-thermoplastic, izixhobo zentsimbi eziqhelekileyo zekristale, isantya sayo sokubumba sicotha, kwaye umbane wokunyibilika ungcono;
Nangona kunjalo, abashicileli be-3D banelifa eliyimbali lentloko ebuhlungu, kulula ukuyiplaga!Nangona izinga lokungaphumeleli komshicileli we-3D liphantsi, xa lithe lenzekile, aliyi kuchaphazela kuphela umgangatho wokushicilela, kodwa liphinde lichithe ixesha kunye nezinto zokushicilela, kwaye bonakalise umatshini.Abantu abaninzi bakrokrela ukuba ityhubhu yomqala ibishushu kakhulu kuba yenziwe ngesongezo.Ngenxa yokuba izixhobo zebakala lobunjineli zifuna ubushushu obuphezulu obuqhubekayo, iimfuno zamacandelo ziphezulu kakhulu.Ngoko ke, umshicileli we-3D usebenzisa ityhubhu ye-PTFE njengetyhubhu yokutya.Izinto ezininzi ekrwada kufuneka zihanjiswe kwintloko yomshicileli kwimeko yokunyibilika, kwaye ityhubhu yothutho kufuneka ihlangabezane neemfuno zendawo yomshicileli, ke ngoku abaninzi abavelisi batshintshela kwi-iron fluorine dragon tube eyakhelwe-ngaphakathi, i-iron fluorine dragon kunye nentsimbi engenasici. I-thermal conductivity iphantsi, inokunciphisa ngokufanelekileyo ubushushu bombhobho womqala, kunye ne-iron fluorine dragon tyhubhu, izinga lokungaphumeleli kweplagi liyancipha kakhulu.Ngoko ke olu lolona khetho lungcono lwabashicileli be3D.
Ukuba ukwishishini lomshicileli we-3D, Ungathanda
Oku kulandelayo kukwaziswa ngokubanzi kweempawu eziphambili zeetyhubhu ze-PTFE:
1. Ingancamathelisi: I-inert, kwaye phantse zonke izinto azidityaniswanga kuyo.
2. Ukumelana nobushushu: i-ferroflurone inokumelana nobushushu obugqwesileyo.Umsebenzi jikelele ungasetyenziswa rhoqo phakathi kwe240℃ kunye ne260℃.Ixesha elifutshane ukumelana nobushushu ukuya kwi-300 ℃ kunye nendawo yokunyibilika ye-327 ℃.
3. Ukuthambisa: I-PTFE ine-coefficient ephantsi yokukhuhlana.I-coefficient ye-friction iyatshintsha xa umthwalo utyibilika, kodwa ixabiso liphakathi kwe-0.04 kunye ne-0.15 kuphela.
4. Ukumelana nemozulu: akukho ukuguga, kunye nobomi obungcono bokungagugi kwiplastiki.
5. I-non-toxic: kwindawo eqhelekileyo ngaphakathi kwe-300℃, ine-inertia ye-physiological kwaye ingasetyenziselwa izixhobo zonyango kunye nokutya.
Ukuthenga i-PTFE ityhubhu elungileyo ayikokukhetha kuphela iinkcukacha ezahlukeneyo kwizicelo ezahlukeneyo.Okunye ukukhetha umenzi othembekileyo.I-Besteflon Fluorine yeplastiki ye-Industry Co., Ltd. igxile kwimveliso ye-PTFE hoses ephezulu kunye neetyhubhu ze-15 iminyaka.Ukuba kukho nayiphi na imibuzo kunye neemfuno, nceda uzive ukhululekile ukudibana nathi ukuze ufumane iingcebiso ezingakumbi.
