Daim ntawv thov
VDF yog ib qho tseem ceeb fluorine-muaj monomer, tuaj yeem npaj polyvinylidene fluoride resin (PVDF) los ntawm ib qho polymerization, thiab npaj F26 fluororubber los ntawm polymerizing nrog perfluoropropene, los yog F246 fluororubber los ntawm polymerizing nrog tetrafluoroethylene thiab perfluoropropene. raws li tshuaj tua kab thiab tshwj xeeb hnyav.
Pob, thauj thiab khaws cia
1.Vinylidene fluoride (VDF) yuav tsum tau muab cia rau hauv lub tank nrog ib qho interlayer uas yog them nrog chilled saline, khaws cov chilled saline tsis tawg.
2.Vinylidene fluoride (VDF) yog txwv tsis pub them nyiaj rau hauv lub tog raj kheej steel.Yog xav tau lub tog raj kheej steel rau kev ntim khoom, nws yuav tsum siv lub tog raj kheej tshwj xeeb uas ua los ntawm cov khoom siv kub-kub.
3 .Steel cylinders them nrog vinylidene fluoride (VDF) yuav tsum tau nruab nrog lub kaus mom kev nyab xeeb uas nruj nreem ntsia hlau rau hauv kev thauj mus los, kom tsis txhob muaj hluav taws.Yuav tsum siv cov khoom siv lub hnub ci thaum thauj mus rau lub caij ntuj sov, tiv thaiv nws los ntawm tshav ntuj.Lub tog raj kheej steel yuav tsum tau thauj khoom thiab thauj khoom me me, kom tsis txhob muaj kev vibration thiab kev sib tsoo.
