Ilaphu le-PTFE elinobushushu obuphezulu (i-PTFE-coated fiberglass) inokumelana nokuxhathisa ukothuka kwe-thermal ngaphakathi koluhlu lwayo lokusebenza oluqhelekileyo lwe--70 °C ukuya kuma-260°C. Iyakwazi ukunyamezela ukukhwela ibhayisekile kobushushu obukhawulezayo, umz., ukusuka kwi--50°C kwisikhenkcisi ukuya kumatshini wokushicilela oshushu wama-260°C. Amabakala ePremium ade aphumelele ukupholisa ngesiquphe ukusuka kwi-260°C ukuya kwi-10°C emanzini. Nangona kunjalo, ukothusa izinto ezivela kumaqondo obushushu angaphezu kwe-300 ° C (kufuphi ne-PTFE's 327 ° C melting point) kuya kubangela ukuqhekeka kunye nokuchithwa kwangoko. I-fiberglass substrate ibonelela ngokuzinza kwe-dimensional; I-PTFE yokwambathisa yinto ethintelayo.

Ilaphu le-PTFE elinobushushu obuphezulu lisetyenziswa kakhulu kushishino lweekhemikhali kwizicelo ezingundoqo ezisixhenxe: iigaskets zeflange kunye nelayini yombhobho (ixhathise i-acids eyomeleleyo/alkali), i-reactor kunye ne-tank linings (ithintela ukubola kwesinyithi, ukucoca lula), iingxowa zokucoca igesi enomhlwa (ukuya kuthi ga kwi-260°C), i-anti-corrosion expansion, i-anti-corrosion extensions ukubumba okuhlanganisiweyo, kunye nokusonga kombane/kwe-thermal. I-FDA kunye ne-UL amabakala akhoyo.

Ilaphu le-PTFE elinobushushu obuphezulu lizinzile ukuya kuthi ga kwi-300 ° C, kodwa emlilweni liyabola kwaye likhuphe iigesi ezinetyhefu kakhulu: i-hydrogen fluoride (HF) (i-corrosive, i-pulmonary edema) kunye ne-perfluoroisobutylene (PFIB) (ayinambala, ayinavumba, ~10x inetyhefu ngakumbi kunephosgene, i-antido). Kwakhona i-carbon monoxide, iintsalela zePFOA, kunye nokulandelela iidioxins. Iimaski zomsi eziqhelekileyo azisebenzi; sebenzisa izixhobo zokuphefumla ezizimeleyo (SCBA). Iimpawu zinokulibaziseka.

Iiarhente zokugqiba umphezulu ezifakwe kwilaphu le-fiberglass phambi kokutyabeka kwe-PTFE zibalulekile kwi-PTFE yokugqibela yokusebenza kwelaphu lobushushu obuphezulu. I-Organosilane coupling agents zenza iibhulorho ze-molecular phakathi kwe-fiber yeglasi ye-inorganic kunye ne-organic PTFE, ukunyusa amandla e-peel ukusuka ku-<2 N / cm ukuya kwi-4-8+ N / cm. Unyango olufanelekileyo luphinda lukhulise ukuxhathisa ukushisa (260 ° C +), ukusebenza kwe-dielectric, kunye nokumelana neekhemikhali. Ilaphu elingaphathwanga likhokelela kwi-delamination, ukugqabhuka, kunye nobomi obufutshane benkonzo.

Ukucoca nokugcinwa ngokufanelekileyo kwandisa ubomi belaphu le-PTFE lobushushu obuphezulu. Coca emva kokusetyenziswa nasemva kokupholisa. Sebenzisa iibhrashi ezithambileyo, izicoci ezingathathi hlangothi, okanye utywala ukwenza amabala. Ungaze usebenzise iiasidi ezomeleleyo/iialkali, iblitshi, okanye izikrweqe zentsimbi. Ukuthambisa ioli ye-silicone rhoqo kunciphisa ukunxiba. Landela ezi zikhokelo ukuthintela ukonakaliswa kwengubo.
