Chifukwa chiyani ma printer a 3D amagwiritsa ntchito machubu a PTFE
Ndi chitukuko chachangu cha nthawi imeneyo, makina osindikizira a 3D ndi mtundu wa ukadaulo wofulumira wa prototyping, womwe umadziwikanso kuti kupanga zowonjezera. Ngakhale kuti kuchuluka kwa kulephera kwa makina osindikizira a 3D kuli kochepa, kulephera kukachitika, sikungokhudza khalidwe losindikiza, komanso kuwononga nthawi yosindikiza zinthu komanso kuwononga makinawo. Makina osindikizira a 3D ali ndi vuto lakale, lomwe ndi losavuta kuletsa! Anthu ambiri amaganiza kuti kutentha kwa chubu cha pakhosi ndi kwakukulu kwambiri, chifukwa ndi kupanga zowonjezera, zinthu zambiri zopangira ziyenera kunyamulidwa mu mkhalidwe wosungunuka wa mutu wa chosindikizira, ndipo chubu chonyamulira chiyenera kukwaniritsa zofunikira za chosindikizira, kotero opanga ambiri tsopano amagwiritsa ntchito. Chubu cha PTFE chomangidwa mkati, kutentha kwa PTFE ndi chitsulo chosapanga dzimbiri ndi kochepa, zomwe zimatha kuchepetsa kutentha kwa pakhosi. Ndi chubu cha PTFE, kuchuluka kwa kulephera kwa pulagi kumachepa kwambiri. Mwanjira imeneyi, machubu a ptfe akhala chisankho chabwino kwambiri cha makina osindikizira a 3D. Pano, mongaopanga machubu a ptfe, Huizhou Zhongxin Fluoroplastic Tube Co., Ltd. idzakufotokozerani chifukwa chake ma printer a 3D sangathe kukhala opanda machubu a PTFE.
Mu 2015, odziwika bwinoWopanga makina osindikizira a 3DAirwolf yatulutsa chosindikizira chake choyamba cha 3D cha anthu wamba. Machubu a Ptfe amagwiritsidwa ntchito m'zigawo zambiri zofunika. Chifukwa chakuti zipangizo zaukadaulo zimafuna kutentha kwambiri kosalekeza, zofunikira pazigawozo zimakhala zapamwamba kwambiri. Chifukwa chake, chosindikizira cha 3D chimagwiritsa ntchito chubu cha PTFE ngati chubu chodyetsa. Mu zosindikizira za 3D, machubu a PTFE amagwiritsidwanso ntchito kwambiri ngati cholumikizira cha machubu a mutu wa extruder. Zifukwa zazikulu apa ndi izi
Kuchita bwino kwa Ptfe:
1. Kusamamatira: PTFE ndi yosagwira ntchito, pafupifupi zinthu zonse sizimalumikizana ndi chubu cha PTFE, ndipo mafilimu opyapyala kwambiri amasonyezanso mphamvu zosamamatira.
2. Kukana kutentha ndi kuzizira: Chubu cha PTFE chili ndi kutentha kwabwino 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, sichimauma mpaka 190℃
3. Kukhuthala: Chubu cha PTFE chili ndi kukhuthala kochepa. Kukhudzika kwa kukhudzika kumasintha pamene katundu akutsetsereka, 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. Kupuma pang'ono, kusunga maola ogwira ntchito ndikuwonjezera magwiridwe antchito.
5. Kukana dzimbiri: Chubu cha PTFE sichimakhudzidwa 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 yoposa 300°C. Udindo wa ma oxidants, ma reducers ndi ma organic solvents osiyanasiyana amatha kuteteza ziwalo ku dzimbiri la mankhwala aliwonse
6. Kukana kwa nyengo: kukalamba sikukalamba, moyo wabwino wosakalamba mu pulasitiki
7. Chopanda poizoni: pamalo abwinobwino mkati mwa 300 ℃, chopanda poizoni, chopanda poizoni chingagwiritsidwe ntchito pazida zamankhwala ndi chakudya
8. Chotetezera kutentha: Chokhazikika bwino 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 chubu cha ptfe, pakadali pano chimagwiritsidwa ntchito m'njira zosiyanasiyana. Chingagwiritsidwe ntchito polimbana ndi dzimbiri, kukana kutentha kwambiri komanso kotsika, komanso kukana dzimbiri. Chimagwiritsidwa ntchito m'malo ovuta monga mafuta odzola, zamagetsi, zida zamagetsi, ndege, ndi chithandizo chamankhwala.
Chiyambi cha kampani:
Huizhou Zhongxin Fluorine Plastic Industrial Co., Ltd si kampani yokhayo yopanga zinthu zapamwamba kwambiri komanso yotsimikizira khalidwe, komanso ili ndi mzere wopanga zinthu zodziyimira pawokha komanso njira yowongolera khalidwe. Kupatula apo, Zhongxin yasankha zinthu zonse kuchokera ku mitundu yoyenerera monga Dupont, 3M, Daikin, ndi zina zotero. Kuphatikiza apo, pali zinthu zopangira zapamwamba kwambiri zomwe mungasankhe. Zipangizo zapamwamba, zinthu zopangira zapamwamba kwambiri, mtengo wabwino ndiye chisankho chanu chabwino kwambiri.
Izi ndi zomwe zili pamwambapa chifukwa chake payenera kukhala chubu cha PTFE kumapeto otentha. Ndikukhulupirira kuti zingakuthandizeni. Ndife ogulitsa chubu cha ptfe ochokera ku China.
Zofufuza zokhudzana ndi chubu cha ptfe:
