Umuyoboro wa PTFE urwanya ubushyuhe bwinshi wo gucapa 3D

PTFE ni iki?

PTFE izwi cyane nka "umwami wa pulasitiki", ni polymer ya polymer ikozwe muri tetrafluoroethylene nk'iy'imashini. Yavumbuwe na Dr. Roy Plunkett mu 1938. Wenda uracyabyumva udasanzwe kuri iyi mashini, ariko wibuka isafuriya idafata twakoresheje? Isafuriya idafata itwikiriwe na PTFE hejuru y'isafuriya, ku buryo ibiryo bidafata hasi mu isafuriya, bigaragaza ubushyuhe bwinshi bwa PTFE n'imiterere yo kwisiga cyane. Muri iki gihe, ibikoresho fatizo bya PTFE bikorerwamo ibintu bifite imiterere itandukanye, nk'imiyoboro ya PTFE, PTFE thin film, PTFE bars, na PTFE plates, byose bikoreshwa mu nzego zitandukanye. Hanyuma, turaganira ku ikoreshwa rya PTFE tubes mu bikoresho bya 3D printer.

Ese PTFE ifite uburozi?

Ingingo yo kumenya niba PTFE ari uburozi iravugwaho rumwe kandi PTFE mu by'ukuri ntabwo ari uburozi.

Ariko ubwo PFOA (Perfluorooctanoic acid) yongerwaga mbere mu bigize PTFE, uburozi bwarasohokaga iyo bukoreshejwe ku bushyuhe bwinshi. PFOA iragoye kuyikuraho iturutse ku bidukikije, kandi ishobora kwinjira mu bantu no mu bindi binyabuzima binyuze mu bintu bifatika, mu mwuka no mu mazi, kandi uko igihe kigenda gihita bishobora gutuma igipimo cy’uburumbuke kigabanuka ndetse n’izindi ndwara z’ubudahangarwa bw’umubiri. Ariko ubu PFOA yarabujijwe n’abayobozi kuyishyira mu bigize PTFE. Raporo zose z’ibizamini byacu by’ibikoresho fatizo zigaragaza ko nta gice cya PFOA kirimo.

Kuki imashini zicapa za 3D zikoresha imiyoboro ya PTFE?

Bitewe n’iterambere ryihuse rya The Times, imashini itunganya 3D ni ikoranabuhanga rikora vuba, rizwi kandi nk’imashini ikora inyongeramusaruro. Ni inzira yo guhuza cyangwa gukurura ibikoresho bigenzurwa na mudasobwa kugira ngo bikore ibintu bifite imiterere itatu, muri rusange hakoreshejwe molekile z’amazi cyangwa uduce tw’ifu kugira ngo bihuzwe hanyuma bikubake ibintu ku rundi ruhande. Kuri ubu, ikoranabuhanga ryo gushushanya 3D muri rusange ririmo: uburyo bwo gushonga, nko gukoresha thermoplastic, ibikoresho by’icyuma bisanzwe bya crystal system, umuvuduko wabyo wo gushushanya ugenda buhoro, kandi uburyo bwo gushonga bw’ibikoresho burushaho kuba bwiza;

Ariko, imashini zicapa za 3D zifite umurage w’amateka w’umutwe, byoroshye kuzifunga! Nubwo igipimo cyo gutsindwa kwa mashini zicapa za 3D kiri hasi, iyo bibaye, ntibizagira ingaruka gusa ku bwiza bw’icapa, ahubwo binapfusha ubusa igihe n’ibikoresho byo gucapa, ndetse bikangiza imashini. Abantu benshi bakeka ko umuyoboro w’umuhogo wari ushyushye cyane kuko wakozwe mu nyongeramusaruro. Kubera ko ibikoresho byo mu rwego rw’ubuhanga bisaba ubushyuhe bwinshi buhoraho, ibisabwa ku bice ni byinshi cyane. Kubwibyo, mashini zicapa za 3D zikoresha umuyoboro wa PTFE nk'umuyoboro wo kugaburira. Ibikoresho byinshi fatizo bigomba kujyanwa ku mutwe w’imashini zicapa mu gihe byashongaga, kandi umuyoboro wo gutwara ugomba kuzuza ibisabwa n’umwanya w’imashini zicapa, bityo abakora benshi bahindura umuyoboro w’imashini zicapa za fluorine, icyuma cya fluorine n’ubushyuhe bw’icyuma kidashonga ni bike, bishobora kugabanya ubushyuhe bw’umuyoboro w’umuhogo, hamwe n’umuyoboro w’imashini zicapa za fluorine, igipimo cyo gutsindwa kwa mashini kiragabanuka cyane. Rero iyi ni yo mahitamo meza ku mashini zicapa za 3D.
