Gabowga tuubada Teflon waa in aan la iska indha tirin

Tubooyinka Teflon waa tuubooyinka fluoroplastic oo laga sameeyay maaddooyinka polytetrafluoroethylene iyadoo la isku qasayo, samaynta uurjiifka, cadaadiista qabow, qaboojinta iyo qaboojinta

Tubooyinka Teflon waxay leeyihiin sifooyin aad u wanaagsan:

①Isku dhufashada hoose;

② Iska caabinta daxalka: caabbinta acid adag iyo alkali, iyo ku dhawaad ​​​​dhammaan kiimikooyinka kama falceliyaan (heerkulka sare iyo fluorine iyo falcelinta birta alkali), waxay iska caabin kartaa "Aqua regia" daxalka;

③Is-nadiifinta: polytetrafluoroethylene way adagtahay in lagu dhego;

④ Aan guban;

⑤ Iska caabin heerkul sare ah: PTFE teflon heerkulku wuxuu gaari karaa -70 ° C ~ 260 ° C;

⑥ Iska caabin sare: Tuubada Teflon oo leh caabbinta sare, wax qabad heer sare ah;

⑦Anti-gabowga: Teflon Tube waxqabadka gabowga ka-hortagga waa mid aad u wanaagsan, adeeg nolol dheer.

Gabowga tuubada PTFE lama iska indho tiri karo, waxqabadka alaabooyinka waa la dhimi doonaa ka dib gabowga, sidaas darteed, wax soo saarka dabayaaqadii, waa inaan fulinaa tallaabooyin taxane ah si looga hortago.

Cajaladda xabagta ee alaabada tubbada Teflon waxaa lagu daaweeyaa habka sulfur. Iska caabbinta kulaylka vulcanizatkeeda waxa lagu wanaajin karaa iyadoo la dhimo ama laga fogaado isticmaalka baaruudda curiyaha ah, taas oo yarayn karta ama baabi'in karta isku-xidhka polysulfide oo inta badan soo saara hal baaruud ama disulfide iskutallaabta.

Isticmaalka peroxide waa lagama maarmaan si loo gaaro caabbinta kulaylka wanaagsan, sida ku daaweynta peroxide waxay soo saartaa isgoysyada kaarboon-kaarboon kuwaas oo ah kuwa heerkulbeeg ah. Fiiro gaar ah waa in la siiyaa waxyaabaha kale ee lagu daro marka la isticmaalayo peroxide. Tusaale ahaan, xulashada antioxidants waxay u baahan tahay inay noqoto mid adag, maadaama qaar badan oo iyaga ka mid ah ay farageliyaan peroxide, vulcanization.

Intaa waxaa dheer, marka la isticmaalayo peroxide, yareeyo qadarka buuxinta acid si looga hortago cations peroxide in ay burburaan, taasoo keentay in vulcanization hoose ee tuubada cadaadis sare (qaab adag hoose, modules hoose iyo set cadaadis sare) . Ku darida xeryahooda aasaasiga ah, sida zinc oxide ama magnesium oxide, halka ay suurtagal tahay, waxay badanaa hagaajin kartaa waxtarka isku-xidhka ee peroxide. Weli waxay leeyihiin saamaynta saliidda paraffin ayaa ka fiican, raba inaad iska ilaaliso isticmaalka saliidda hydrocarbon udgoon iyo dareeraha.
