Chubu cha PTFE chotentha kwambiri cha osindikiza a 3D | BESTEFLON

Popeza zipangizo zamakono zimafuna kutentha kosalekeza kwa ma printers a 3D, zofunikira pazigawo zake zimakhala zapamwamba. Chifukwa chake, ma printer a 3D amagwiritsa ntchitoChubu cha PTFEmonga chubu chodyetsera (chubu chodyetsera). Machubu a PTFE amagwiritsidwa ntchito kwambiri mumakampani osindikizira a 3D, makamaka chifukwa cha magwiridwe antchito awa:

Kusamamatira: PTFE ndi yosagwira ntchito, pafupifupi zinthu zonse sizimalumikizana ndi chubu cha PTFE, ndipo mafilimu opyapyala kwambiri amasonyezanso mphamvu zosamamatira.

Kukana kutentha ndi kuzizira: Chubu cha PTFE chili ndi kutentha kwabwino kwambiri komanso kukana kutentha kochepa. Chimatha kupirira kutentha mpaka 300℃ pakapita nthawi yochepa, ndipo malo osungunuka ndi 327℃. Sichisungunuka pa 380℃. Nthawi zambiri, chingagwiritsidwe ntchito nthawi zonse pakati pa 240℃ ndi 260℃. Chili ndi kukhazikika kwa kutentha kwakukulu. Chimatha kugwira ntchito kutentha kozizira. Sichimauma, sichimauma, sichimapirira kuzizira mpaka 65℃.

3. Kukhuthala: Chubu cha PTFE chili ndi kukhuthala kochepa. Kukhuthala kwa kugwedezeka kumasintha pamene katundu ukutsetsereka, koma mtengo wake ndi pakati pa 0.04-0.15 yokha.

4. Kusakhala ndi hygroscopicity: Pamwamba pa chubu cha PTFE sipamamatira ku madzi ndi mafuta, ndipo sikophweka kumamatira ku yankho panthawi yopanga. Ngati pali dothi laling'ono, likhoza kuchotsedwa pongopukuta. Kuchepetsa nthawi yogwira ntchito, kusunga maola ogwira ntchito ndikuwonjezera magwiridwe antchito.

5. Kukana dzimbiri: Chubu cha PTFE sichimatenthedwa ndi mankhwala, ndipo chimatha kupirira ma asidi onse amphamvu (kuphatikizapo aqua regia), ma alkali amphamvu, ndi ma acid amphamvu kupatula zitsulo zosungunuka za alkali, fluorinated media, ndi sodium hydroxide pamwamba pa 300°C. Ntchito ya ma oxidants, zochepetsera zinthu ndi zinthu zosiyanasiyana zachilengedwe zimatha kuteteza ziwalo ku dzimbiri la mankhwala.

6. Kukana nyengo: palibe ukalamba, moyo wabwino wosakalamba mu pulasitiki.

7. Chopanda poizoni: pamalo abwinobwino mkati mwa 300 ℃, chosagwira ntchito mwachibadwa, chopanda poizoni chingagwiritsidwe ntchito pazida zamankhwala ndi chakudya.

8. Chotetezera kutentha: Chokhazikika bwino kwambiri cha dielectric komanso choteteza kutentha kwambiri.

9. Kuchuluka kwa kukangana ndi kochepa, ndipo kusinthasintha kwa zipangizo zopangira ndi kwabwino.

Chifukwa cha ntchito yabwino kwambiri ya payipi ya PTFE, si yoyenera makampani osindikizira a 3D okha, komanso imagwiritsidwa ntchito kwambiri polimbana ndi dzimbiri, kutentha kwambiri, kutentha kochepa komanso kukana dzimbiri. Ndipo imagwiritsidwa ntchito m'malo ovuta monga mafuta odzola, zamagetsi, zida zamagetsi, ndege ndi chithandizo chamankhwala.
