Dharka heerkulka sare ee PTFE waxaa si ballaaran loo isticmaalaa warshadaha kiimikada ee toddobada codsiyo muhiim ah: flange gaskets iyo dahaarka tuubada (iska caabiya acids / alkalis xoog leh), reactor iyo dahaarka taangiga (hortagga daxalka biraha, nadiifinta fudud), bacaha filter gaaska daxalka ah (ilaa 260 ° C), kala-goysyada ballaarinta maro koronto, anti-padssion. daboolka dahaadhka. FDA iyo UL darajooyin la heli karo.

Walaxaha dhamaystiraya dusha sare ee lagu dabaqo marada fiberglass ka hor inta aan daahan PTFE muhiim u ahayn waxqabadka PTFE ee ugu dambeeya ee maro heerkul sare ah. Wakiilada isku xidhka Organosilane waxay abuuraan buundooyin molecular oo u dhexeeya fiber galaas ah iyo PTFE organic, kor u qaadaya xoogga diirka <2 N/cm ilaa 4-8+ N/cm. Daawaynta saxda ah waxay sidoo kale wanaajisaa caabbinta kulaylka (260°C+), waxqabadka dielectric, iyo caabbinta kiimikada. Dharka aan la daweynin waxay horseedaa delamination, xumbo, iyo nolol adeeg oo gaaban.
