Yintoni eyenza ilaphu leFiberglass eligqunywe nge-PTFE liNganantonga?

Ubuchule obumangalisayo be Ilaphu le-PTFE elakhiwe ngefiberglass eligqunywe ukuba lingancamatheli kungenxa yesakhiwo semolekyuli esikhethekileyo sepolytetrafluoroethylene (PTFE), enika i-fiberglass substrates amandla aphantsi kakhulu kumphezulu. Le ngubo ye-fluoropolymer ineathom ze-fluorine ezidibanisa kakhulu nekhabhoni. Oku kwenza umphezulu womhlaba ungasebenzi ngokwekhemikhali kwaye umelane nezinto ezininzi. Umaleko olinganayo, ogudileyo we-PTFE wehlisa ukuxinezeleka komphezulu kwaye unqande imathiriyeli efana nokutya, izinto zokuncamathelisa, kunye neekhompawundi zemizi-mveliso ukuba zingancangathi. Oku kwenza kube lukhetho olukhulu kwiinkqubo zokuvelisa ezifuna iimpawu ezithembekileyo zokukhululwa.

Ukuqonda i-PTFE Coated Fiberglass Fabric kunye neNdalo yayo engeyiyo intonga

Inzululwazi emva kweempawu ezinganamatheli zivela kwiimolekyuli ezenza i-PTFE yokwambathisa ebekwe phezu kwefiberglass elukiweyo. Iimolekyuli ze-PTFE zenziwe ngeeathom zekhabhoni kunye neeathom zefluorine macala onke kuzo. Oku kwenza ukuba ibe yenye yezona zinto zizinzileyo kwiikhemikhali ezisetyenziswa kwishishini. Amandla omphezulu wale pateni yeemolekyuli aphantsi njenge-18-20 dynes ngesentimitha, engaphantsi kakhulu kunezinye izinto ezininzi.

Xa abavelisi basebenzisa iindlela zokwaleka ezikhethekileyo ukongeza i-PTFE kwilaphu le-fiberglass, benza izinto ezidibeneyo ezinokomelela kweentsinga zeglasi kunye neempawu ezinkulu zokukhupha ze-fluoropolymers. Ngenxa yoku, ilaphu lihlala lilingana kwaye ligcina iimpawu zalo ezingabambekiyo kumaqondo obushushu asuka ku -70°C ukuya kuma-260°C.

Ifiberglass engacocwanga inemigangatho erhabaxa, enemingxuma ekulula ukuba ungcoliseko kunye nemathiriyeli ibambelele kuyo. Iinguqulelo ezigqunywe nge-PTFE, kwelinye icala, zinemigangatho egudileyo, eqhubekayo engavumeli ukwakheka kwenzeke kwaye kulula ukuyicoca. Ngexesha lenkqubo yokwaleka, amasuntswana e-PTFE angena kwi-fiberglass weave kwaye enze ikhaka elikhusela umonakalo kwaye ligudise umphezulu.

Izinto eziluncedo ezingundoqo zePTFE Coated Fiberglass Fabric kwi-Industrial Settings

Ukusetyenziswa kwemizi-mveliso, izixhobo kufuneka zisebenze rhoqo nangona iimeko zinzima. Izibonelelo ezininzi ze-PTFE ezigqunywe ngelaphu le-fiberglass ziyenza ibaluleke kwimimandla emininzi yemizi-mveliso.

Ngenxa yokumelana nobushushu obuphezulu, inokusetyenziswa ngokuqhubekayo kwiindawo apho ezinye izinto ziya kuphuka okanye ziyeke ukuba zinganamatheli. Ngokomzekelo, iifektri ezenza izinto ezibhakiweyo zixhomekeke kolu kuzinzo lwe-thermal ukugcina ukukhutshwa kweemveliso zabo rhoqo ngexesha lokusebenza kobushushu obuphezulu.

Ukumelana nemichiza yenye inzuzo ebalulekileyo. Iiasidi, iziseko, izinyibilikisi, kunye nee-oyile ezisetyenziswa rhoqo kwiinkqubo zemizi-mveliso azichaphazeli i-PTFE yokwambathisa.
