Steel lined izixhobo ptfe ngokuqhelekileyo zenziwe ngezibuko lokukhupha, izibuko feed, isibuko imbono, njl, kodwa indlela yokufaka ngempumelelo olu hlobo lombhobho kumgca entsonkothileyo ukunqumla intloko, Kakade ke, impendulo yethu ukuwelda, ngoko njani ukuwelda? Indlela yokulawula ubushushu be-ptfe welding?Ngezantsi sichazela enye nganye.

Indlela yokulawula ubushushu be-ptfe welding?Ngezantsi sichazela enye nganye.
1, ptfe intloko umbhobho umlomo imveliso
PTFE umbhobho welding kwintloko yokutywina ukuya kuqala kuzo zonke, kufuneka senze PTFE ukutywina intloko umlomo wombhobho, ngokobungakanani bombhobho ububanzi intloko yentsimbi kwaye ngokomlinganiselo othile ngokusebenzisa umgubo ukubumba inkqubo yokuvelisa umlomo wombhobho, iiyure ezisi-8 sintered phantsi 380 plus okanye thabatha 5 degrees Celsius, emva kokugqitywa sintering umlomo wombhobho elungileyo kunye lathe imoto ukuya ubukhulu obufanelekileyo, siyavuyisana PTFE ityhubhu ngalo mzuzu ugqibile.
2, ptfe intloko ukuvula
Beka intloko ekhutshiweyo kwintloko yentsimbi, kwaye usebenzise umgaqo wokuhanjiswa kokukhanya ukuvula ngokuchanekileyo intloko, ingqalelo kwintloko ye-ptfe kufuneka ihambelane nentloko yentsimbi, okanye izixhobo zokugqibela zixhomekeke kwi-bulge, ukuphuka kunye nezinye iingozi ezinokubakho. .
3, ptfe umbhobho welding umlomo
Ngamanyathelo amabini okuqala, sinokuqhuba i-PTFE welding.Apha siyazi ukuba kukho iindlela ezimbini ze-welding (i-welding eshushu kunye ne-hot air welding).Siza kuzichaza nganye nganye.
(1) ukuwelda ngoxinzelelo olushushu
Phambi ukuwelda uxinzelelo olushushu kufuneka sazi ulwazi oluyimfuneko theory, ukuwelda uxinzelelo eshushu luhlobo ukuwelda eshushu, ukunika ubushushu ngokwaneleyo kunye noxinzelelo ngokwaneleyo. Apha, kufuneka siqinisekise ukuba ujongano lobushushu ujongano welding kufuneka ukufikelela 673.15k kwaye uxinzelelo lufikelela 1-2mpa .Ngoko ke, ukuze kuqinisekiswe ukuwelda, kufuneka senze iimbumba ezihambelanayo ukuqinisekisa ukugqitywa ngempumelelo kwe-thermal pressure welding.Xa zonke zenziwe, ifilimu ye-FEP inokudityaniswa ngoxinzelelo kunye nokufudumeza ujongano phakathi kombhobho kunye nentloko.
(2) ukuwelda umoya oshushu
Ngokufanayo, i-ptfe ye-welding yomoya oshushu luhlobo lwe-welding eshushu, elula kakhulu kunoxinzelelo olushushu lwe-welding kwaye ayifuni iimbumba ezininzi.Emva kokubeka umlomo wombhobho, intonga ye-PFA ye-welding kunye nompu we-welding womoya oshushu ongaphezulu kwe-713K zisetyenziselwa ukutshisa i-PFA kuqala kwaye emva koko uyibeke kumthungo we-welding ukwenzela ukuwelda okuqhubekayo.
Qaphela: nokuba kushushu ukuwelda iqondo lobushushu okanye umoya oshushu welding iqondo lobushushu iya kuba phezulu kunendawo yokunyibilika ptfe, ptfe kunokwenzeka phantsi kokuqhekeka lobushushu, ivelisa kwinkqubo pyrolysis perfluorinated isobutylene kunye nezinye iigesi ezinetyhefu, ngoko ukuwelda kufuneka ibe kwi. indawo yokungena umoya, xa imeko ingavumeli ezifana ne-fluorine lining tank welding emine kwimveliso kufuneka isebenzise isiqinisekiso sokuhamba komoya se-fan kunye nokunxiba imaski yegesi ukuqinisekisa ukhuseleko ngexesha elifanayo.
