Kutentha kwambiri kwa PTFE chubu kwa osindikiza a 3D |Malingaliro a kampani BESTEFLON

Popeza zida zamakalasi a uinjiniya zimafunikira kutentha kosalekeza kwa osindikiza a 3D, zofunikira zamagulu ndizokwera.Chifukwa chake, chosindikizira cha 3D chimagwiritsa ntchitoPTFE chubumonga chubu chodyetsera (chodyetsa chubu).Machubu a PTFE amagwiritsidwa ntchito kwambiri mumakampani osindikizira a 3D, makamaka chifukwa cha izi:

Kusamamatira: PTFE ndi inert, pafupifupi zinthu zonse sizimalumikizidwa ndi chubu la PTFE, komanso makanema owonda kwambiri amawonetsanso zinthu zopanda ndodo.

Kutentha ndi kuzizira: chubu la PTFE lili ndi kutentha kwambiri komanso kukana kutentha kochepa.Imatha kupirira kutentha mpaka 300 ℃ pakanthawi kochepa, ndipo malo osungunuka ndi 327 ℃.Sichisungunuka pa 380 ℃.Nthawi zambiri, imatha kugwiritsidwa ntchito mosalekeza pakati pa 240 ℃ ndi 260 ℃.Lili ndi kukhazikika kwa kutentha kwapadera.Ikhoza kugwira ntchito pa kutentha kwachisanu.Palibe embrittlement, kukana kuzizira kwa 65 ℃.

3. Lubricity: PTFE chubu ili ndi coefficient yochepa ya kukangana.Mkangano wa coefficient umasintha pamene katundu akutsetsereka, koma mtengo umangokhala pakati pa 0.04-0.15.

4. Non-hygroscopicity: Pamwamba pa chubu cha PTFE sichimamatira kumadzi ndi mafuta, ndipo sikophweka kumamatira ku yankho panthawi yopangira ntchito.Ngati pali dothi laling'ono, likhoza kuchotsedwa mwa kungopukuta.Kupuma kwakanthawi kochepa, kupulumutsa nthawi yogwira ntchito komanso kukonza magwiridwe antchito.

5. Kukana kwa dzimbiri: chubu cha PTFE sichimawonongeka ndi mankhwala, ndipo chimatha kupirira ma acid onse amphamvu (kuphatikizapo aqua regia), alkali amphamvu, ndi ma acid amphamvu kupatula zitsulo zosungunuka za alkali, fluorinated media, ndi sodium hydroxide pamwamba pa 300 ° C.Udindo wa okosijeni, kuchepetsa wothandizila ndi zosiyanasiyana zosungunulira organic akhoza kuteteza mbali ku mtundu uliwonse dzimbiri mankhwala.

6. Kukana kwanyengo: palibe ukalamba, moyo wabwino wosakalamba m'mapulasitiki.

7. Zopanda poizoni: m'malo abwinobwino mkati mwa 300 ℃, physiologically inert, yopanda poizoni ingagwiritsidwe ntchito ngati zida zamankhwala ndi chakudya.

8. Insulation: Zabwino kwambiri za dielectric mosasintha komanso kutsekereza kwakukulu.

9. Mkangano wachitsulo ndi wochepa, ndipo madzi amadzimadzi ndi abwino.

Chifukwa cha ntchito yabwino ya PTFE payipi, si oyenera makampani 3D chosindikizira, komanso ankagwiritsa ntchito payipi anticorrosion, kutentha, kutentha otsika ndi kukana dzimbiri.Ndipo amagwiritsidwa ntchito m'malo ovuta monga mafuta, zamagetsi, zida zamagetsi, zakuthambo ndi chithandizo chamankhwala.
