Foornooyinka sibidhka, kuwa qashinka lagu gubo, kuleyliyayaasha lagu shido dhuxusha, iyo dhirta kiimikaad waxay dhaliyaan gaasyo kulul, daxalaysan, boodh ku raran oo si degdeg ah u burburiya bacaha caadiga ah. Sifeynta dareeraha ah ee ku lug leh asiidh xooggan ama saliidaha heerkulka sare waxay dalbanayaan warbaahinta aan hoos u dhicin, bararin, ama aan daadin fiilooyinka.
PTFE dhar heerkul sare leh - fiberglass-dahaarka leh ee PTFE - ayaa noqday xalka loogu talagalay bay'adahan sifaynta adag. Isku dhafka kulaylka 260°C, qallafsanaanta kiimikaad, dusha aan dhegta lahayn, iyo xasilloonida cabbirka ayaa ka dhigaysa lama huraan u ah ururinta boodhka bacaha, marayaha shaandhada dareeraha ah, iyo filtarrada hawada waxtarka leh.
Tani waa goobta ugu weyn ee la isticmaalo, halkaas oo dharka heerkulkiisu sarreeyo ee PTFE lagu farsameeyo bacaha shaandhada ama loo isticmaalo agabka aasaasiga ah ee kuwa boorsada aruuriya.

Foomamka Alaabta: Maro fiberglass ah oo lagu sammeeyay emulsion PTFE, ama lagu dhejiyay xuubka microporous ee PTFE oo la fidiyay (wax shaandhayn xuub leh). Laminate xuubka wuxuu gaaraa sifaynta dusha sare, si aad ah u wanaajisa waxtarka iyo awood u yeelashada u hoggaansanaanta qiiqa aadka u hooseeya (<5 mg/Nm³).
Aokai PTFE waxa ay siisaa PTFE-dahaarka ka samaysan fiberglass shaandhada bacda. Waxaan bixinaa labada buundooyinka caadiga ah ee dharka la isku dayay iyo darajooyinka xuub-ku-xidhan. Dharkayaga waxaa lagu ansaxiyay weel sibidh ah iyo kuwa qashinka lagu gubi karo oo leh 260°C hawlgal joogto ah iyo u hogaansanaan siidayn.
Heerkulka Sare & Shaandhaynta Dareeraha Dabiiciga ah ee Adag
Ka faa'iidaysiga firfircooni la'aanta kiimikada aadka u wanaagsan iyo iska caabinta heerkulka ballaaran, dharka PTFE wuxuu u adeegaa sida maro shaandhaynta dareeraha ah iyo mesh taageeraya.

Ku talinaynaa Fabric PTFE?
Sababta Koowaad
Bacaha heerkulka sare (>200°C)
✅ Haa
Kaliya ikhtiyaar wax ku ool ah oo joogto ah 260 ° C
Gaaska hawada wasakhaysan (asiidh)
✅ Haa
Waxay u adkaysataa HCl, SOₓ, dambaska dioxin-ku raran yahay
Boodh dhegdheg leh (kaarboon madow, sibidh)
✅ Haa
Siidaynta aan dhegta lahayn; nadiifinta fudud
Sifeynta dareeraha aashitada/alkali ee xooggan
✅ Haa (marka laga reebo HF)
Kiimiko la'aanteed lama barbar dhigin
Sifeynta nadiifka ah ee cuntada/farmasiga
✅ Haa
FDA, uumi jeermis dili kara, aan lahayn fiber-ka daadsan
Heerkulka hooseeya (<100°C) hawo aan qudhun lahayn
⚠️ Tixgeli polyester/PPS
PTFE waa mid xad dhaaf ah oo ka qaalisan
Adeegga dareeraha aashitada Hydrofluoric
❌ Iska ilaali
HF waxay ku weerartaa substrate-ka fiberglas-ka iyada oo loo marayo godad dahaarka ah
Marka la soo koobo , PTFE dhar heerkul sare leh ayaa ah xal qaali ah oo loogu talagalay xaaladaha shaqada ee sifeynta xad dhaafka ah. Waxay u taagan tahay shaandhada la door biday ama lagama maarmaanka u ah xaaladaha ku lug leh heerkulka sare (ilaa 260 ° C joogto ah), daxalka acid-alkali ee xooggan, iyo boodhka dhegdhegaysan. Gaar ahaan lama bedeli karo marka la saaro boorsada heerkulka sare leh (sibidhka, gubi qashinka, kuleyliyaha dhuxusha) iyo kala soocida dareeraha adag ee wasakhaysan.
Xaaladaha baahida yar, warbaahinta qiimaha jaban sida polyester, PPS, ama aramid ayaa ku filnaan karta. Laakiin marka deegaanku uu riixo xadka - 260 ° C, barta sayaxa aashitada, ama qaybo dhejis ah - PTFE-dahaarka muraayadaha fiberglass-ka ayaa bixiya waxqabad la isku halayn karo, muddo dheer soconaya.
