Pwm silicone ua haujlwm txoj kev
1. Pwm ua Mould silicone thiab curing tus neeg sawv cev yog sib xyaw ua ke. Txoj kev tsim ntawm silicone roj hmab pwm thiab ceev faj. Txoj kev tsim ntawm silicone roj hmab pwm thiab ceev faj. Cov tsos ntawm pwm silicone yog cov kua dej ntws. Cheebtsam A yog silicone thiab cov khoom B yog curing agent. Piv txwv li, noj 100 grams ntawm silicone thiab ntxiv 2 grams ntawm curing agent (Ceeb toom: silicone thiab curing agent yuav tsum sib tov sib npaug. Yog tias lawv tsis sib tov sib npaug, cov pwm yuav tsis sib npaug thiab qhuav, uas yuav cuam tshuam rau lub neej kev pab cuam. ntawm silicone pwm thiab tus naj npawb ntawm pwm flips, thiab txawm ua rau cov pwm yuav tsum scrapped.
2. Nqus thiab tshem tawm npuas. Tom qab cov silicone thiab curing tus neeg sawv cev sib xyaw ua ke, lub tshuab nqus tsev thiab tshem tawm npuas yog nqa tawm. Lub sijhawm nqus tsev yuav tsum tsis txhob ntev dhau, feem ntau tsis tshaj 10 feeb, txwv tsis pub, cov silicone yuav tsim cov tshuaj tiv thaiv kab mob sib kis thaum kho, thiab nws yuav tsis tuaj yeem txhuam los yog nchuav, ua rau cov khoom pov tseg.
3. txhuam cov txheej txheem ua haujlwm. Ncuav cov silicone uas tau de-bubbled rau ntawm tus tswv pwm los ntawm txhuam los yog nchuav (ua ntej txhuam los yog nchuav, thov tus neeg sawv cev cais lossis tso tawm ntawm tus tswv pwm). Kev txhuam hniav yuav tsum sib npaug. Tom qab 30 feeb, lo ib txheej ntawm gauze los yog fiberglass daim ntaub kom lub zog thiab nro ntawm pwm; txhuam nws ob zaug, thiab tom qab ntawd lo ib txheej ntawm gauze lossis fiberglass daim ntaub. Tom qab ntawd siv silicone. Cov pwm kho nyob rau hauv txoj kev no muaj lub neej ua haujlwm ntev thiab ntau lub sijhawm pwm hloov pauv, lub neej ua haujlwm ntev, txuag nqi thiab txhim kho kev ua haujlwm zoo. Tsab ntawv "Silicone Rubber Pwm Ua Txoj Kev thiab Kev Ceeb Toom" yog los ntawm Aokai Precision Pwm! .
4. Ua cov pwm sab nrauv. Txoj kev dav dav yog nyob ib puag ncig cov pwm nrog cov ntawv yas lossis cov rooj ntoo. Ib qho yog sau cov pwm thav duab nrog plaster. Lwm cov pwm sab nrauv yog siv cov txhuam hniav. Siv ib txheej ntawm resin, ib txheej ntawm iav fiber ntau daim ntaub, thiab ces txhuam thiab muab tshuaj txhuam. Rov ua ob lossis peb txheej kom tiav cov pwm txheej. 5. Qhov piv ntawm silicone (silicone, silicone) rau curing agent qhia txog qhov xwm txheej. Nws raug pom zoo tias tus nqi kho mob ntxiv yuav tsum tsis pub tshaj 5%. Qhov loj dua qhov kev faib ua feem ntawm tus neeg sawv cev kho ntxiv, lub sijhawm kho sai dua, cov pwm ntau dua, thiab lub neej ua haujlwm luv dua. Raws li cov khoom thiab cov txheej txheem yuav tsum tau, cov roj silicone tuaj yeem muab ntxiv rau qhov tsim nyog kom ua tiav cov nyhuv molding zoo dua. Nco ntsoov tias cov roj silicone yuav tsum tsis txhob ntau dhau (5%-10%), txwv tsis pub, nws yuav cuam tshuam rau lub zog tensile thiab hardness ntawm silicone pwm.
