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, ua kom cov kua qaub chilled tsis tawg.

2.Vinylidene fluoride (VDF) yog txwv tsis pub them nyiaj rau hauv lub tog raj kheej steel.Yog tias xav tau lub tog raj kheej steel rau ntim, nws yuav tsum siv cov thooj voos kheej kheej tshwj xeeb uas ua los ntawm cov ntaub ntawv tsis tshua muaj 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 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.
