Chaza umehluko phakathi kwebhodi le-epoxy glass fiber nebhodi le-PTFE ngokuningiliziwe

Namuhla, ngingathanda ukwabelana nawe umehluko phakathi kwebhodi le-epoxy glass fibre kanye nebhodi le-PTFE, khona-ke ake sikubheke ndawonye.

Okokuqala, sidinga ukwazi ukuthi iyini ibhodi ye-epoxy glass fiber kanye nebhodi le-PTFE.

Amapuleti e-PTFE ahlukaniswe abe izinhlobo ezimbili: amapuleti abunjiwe namapuleti aphendukile. Amapuleti abunjiwe enziwe nge-polytetrafluoroethylene resin ngokubunjwa ekamelweni lokushisa, bese efakwa futhi epholile. Ibhodi elijikayo lenziwe nge-PTFE resin ngokucindezela, ukucwilisa, nokucwecwa. Kunezinhlobo ezimbili zamapuleti e-PTFE: amapuleti abunjiwe namapuleti aphendukile. Amapuleti abunjiwe enziwe nge-polytetrafluoroethylene resin ngokubunjwa ekamelweni lokushisa, bese efakwa futhi epholile. Ibhodi elijikayo lenziwe nge-PTFE resin ngokucindezela, ukucwilisa, nokucwecwa. Ukumelana nokushisa okuphezulu kufika ku-250 ℃, ukumelana nokushisa okuphansi -196 ℃, ukumelana nokugqwala, ukumelana nesimo sezulu, ukugcotshwa okuphezulu, ukunganamatheli nezinye izici. Ngaphandle kwensimbi ye-alkali encibilikisiwe, ipuleti le-PTFE aligqwali nganoma yimaphi ama-reagents amakhemikhali. Isibonelo, ku-sulfuric acid egxilile, i-nitric acid, i-hydrochloric acid, noma ngisho ebilisiwe ku-aqua regia, isisindo sayo nokusebenza kwayo akuguquki, futhi cishe ayincibiliki kuzo zonke izincibilikisi.

I-epoxy glass fibre board ibizwa nangokuthi i-epoxy glass fiber board, ibhodi lendwangu yengilazi epoxy phenolic elaminethiwe, i-epoxy resin isho inhlanganisela ye-polymer ephilayo equkethe amaqembu amabili noma ngaphezulu epoxy ku-molecule. Isisindo samangqamuzana esihlobene asiphezulu. Isakhiwo samangqamuzana e-epoxy resin sibonakala ngeqembu le-epoxy elisebenzayo kuchungechunge lwamangqamuzana. Iqembu le-epoxy lingatholakala ekugcineni, phakathi nendawo noma esakhiweni se-cyclic seketango lamangqamuzana. Ngenxa yokuthi ukwakheka kwamangqamuzana kuqukethe amaqembu e-epoxy asebenzayo, angabhekana nokusabela okuxhumanisa ngezinhlobo ezahlukene zama-ejenti okwelapha ukuze akhe ama-polymer angancibilikiyo futhi angenakunyakaziswa anesakhiwo senethiwekhi yezindlela ezintathu.

Ngakho-ke uyini umehluko phakathi kwebhodi le-epoxy glass fibre nebhodi le-PTFE?

Ibhodi le-PTFE lenziwe nge-polytetrafluoroethylene resin ngokusebenzisa inqubo ekhethekile njengokubumba, ukucindezela kwamanzi, ukuphenduka, njll. Ukusebenza kwayo kungakwazi ukumelana nokushisa okuphezulu kwama-degrees angu-260. I-epoxy glass fiber board yenziwe nge-glass fibre efakwe i-epoxy resin glue kanye ne-ejenti yokwelapha. , Ukumelana nezinga lokushisa cishe kungama-degree angu-100, ibhodi le-PTFE lingakwazi ukumelana nanoma iyiphi i-asidi ne-alkali, futhi i-epoxy yesaba i-asidi eqinile. Ngokombono wokuhlukaniswa kwepulasitiki, eyokuqala ingeyepulasitiki ye-thermoplastic, kanti lena eyokugcina ingeyepulasitiki ye-thermosetting. I-epoxy glass fiber board inamandla aphezulu ekamelweni lokushisa.
