Yuav ua li cas tiv thaiv petg los ntawm deforming?
Dec 31, 2024| Nyob rau lub 3D - cov txheej txheem luam ntawv
Txhim kho qhov kub luam ntawv txias: PETG feem ntau muaj qhov pom zoo luam tawm kub thiab txias ntawm ib ncig 220 - 250 degree. Kev tswj kom muaj kev sib haum xeeb thiab tsim nyog luam ntawv ntsuas kub pab kom ntseeg tau tias cov khoom siv yog extruded thiab tso nyiaj ntau. Piv txwv li, yog tias qhov ntsuas kub siab dhau, cov khoom yuav tau tshoov dhau thiab txias tsis ncaj, ua rau kev ua rog.
Tswj Cov Tshuab Luam Ntawv Ceev: Ib txwm luam ntawv luam tawm yog qhov tseem ceeb heev. Kev nrawm nrawm nrawm tuaj yeem ua rau tsis txaus txias ntawm cov ntawv luam tawm. Cov kev pom zoo kom luam ntawv ceev rau PetG nyob ib ncig ntawm 30 - 60 hli / s. Kev nrawm nrawm ntawm kev luam tawm thaum tsim nyog tso cai rau txias thiab solidfify tau ntxiv, txo txoj kev pheej hmoo ntawm kev ntxhov siab.
Xyuas kom zoo txaj adhesion thiab cua txias:
Siv daim ntawv tsim tsa tsim kom haum nrog cov nplaum zoo, xws li Pei - coated lossis textured tsim phaj. Koj tseem tuaj yeem thov cov nplaum zoo li cov nplaum nplaum zoo li cov nplaum nplaum kom txhim kho cov nplaum ntawm thawj txheej ntawm Petg mus rau lub thawv tsim.
Nruab ib qho zoo kiv cua txias. Nco ntsoov tias huab cua txias yog cov neeg muaj tseeb ntawm cov ntawv luam tawm los txhawb cov khaub ncaws cua txias. Piv txwv li, ob lub teeb tsa dual - teeb tsa tuaj yeem muab cov cua txias ntau rau cov khoom sib txawv ntawm cov khoom luam tawm.
Hauv kev tshaj tawm - kev ua thiab siv theem
Kev Kho Mob Anneal: Annealing yog tshav kub - kev kho txheej txheem uas tuaj yeem txo kev ntxhov siab sab hauv hauv Petg. Cov txheej txheem dav dav yog kom sov cov luam tawm ib feem mus rau qhov kub thiab txias dua nws khob - kev hloov ntsuas kub (nyob ib ncig} degree) thiab maj mam txias nws. Qhov no pab ua cov qauv molecular ntawm cov khoom ruaj khov thiab txo cov peev txheej rau kev ua yeeb yaj kiab.
Zam kev mob siab:
Khaws cov khoom lag luam petg deb ntawm qhov chaw siab - qhov chaw kub uas tau tshaj nws cov cua sov - deformation kub. Yog tias nws tau siv sab nraud, txiav txim siab ntxiv shading lossis cua sov - rwb thaiv tsev ntsuas hauv huab cua kub. Piv txwv li, rau sab nraum zoov cov phiajcim, koj tuaj yeem nruab ib qho me me AWNING saum toj no lawv kom txo lub hnub ci ncaj qha raug.
Txo qhov ntev - cov lus thov ntawm kev tsis sib xws sab nraud rog. Thaum tsim cov khoom lag luam tsiaj xws li cov qauv lossis cov qauv, muaj peev xwm ua rau muaj kev cuam tshuam - kev ntxhov siab yog tsim nyog deformation vim ntev - kev ntxhov siab.
