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.

Ilaphu le-PTFE elinobushushu obuphezulu kunye nelaphu le-silicone zombini zisebenzisa ilaphu le-fiberglass njengesiseko kodwa ziyahluka kwizinto zokwaleka (i-PTFE resin vs irabha ye-silicone). I-PTFE igqwesile ekungabambeni, ukuxhathisa ukunxiba, kunye nokumelana neekhemikhali ukuya kuthi ga kwi-260°C. Ilaphu le-Silicone linika ukuguquguquka okuphezulu, ukugquma kombane, kunye nokumelana nomlilo (ukuya kuma-230 ° C). Khetha ngokusekelwe kukubaluleka kwakho.

Ilaphu le-PTFE elinobushushu obuphezulu libonelela ngokuxhathisa okukhethekileyo kweekhemikhali, ukumelana neeasidi ezomeleleyo, iialkali, izinyibilikisi eziphilayo, kunye neegesi ezidliwayo. Eli nqaku lichaza izinto zalo ezixhathisayo, imida (isinyithi esinyibilikisiweyo se-alkali, i-agent eqinile ye-fluorinating), kunye nezinto eziphambili ezifana nobushushu, ugxininiso, kunye noxinzelelo lomatshini.

Ukufakwa kwe-PTFE akuphelelanga kwilaphu le-fiberglass. Eli nqaku lizisa ii-substrates ezi-7 ezizezinye - i-aramid, i-carbon fiber, i-PBI, isinyithi esine-porous, i-graphite, i-asbestos (ikhutshwe ngaphandle), kunye ne-ceramic fillers - kunye neempawu zabo zenkqubo, izibonelelo, ukulinganiselwa, kunye nezicelo eziphambili.

Eli nqaku licacisa ukuba kutheni ilaphu le-fiberglass engena-alkali iyeyona ikhethwayo kwilaphu le-PTFE lobushushu obuphezulu. Igquma ukudityaniswa kweekhemikhali kusetyenziswa i-silane coupling agents kunye neepropathi eziphambili zomzimba ezifana nokuzinza kwe-thermal, ukuzinza komda, kunye nokumelana nomhlwa-ukuqinisekisa ukusebenza okuhlala ixesha elide kwiindawo ezirhabaxa.

Njengomvelisi oqeqeshiweyo wamalaphu obushushu obuphezulu be-PTFE, iJiangsu Aokai New Materials yabelana nawe ngolwazi olufanelekileyo lweshishini. I-Edge warping kunye nokuwa kwe-PTFE iiteyipu zokushisa eziphezulu azifane zibangelwa yinto enye, kodwa zibangelwa kwimiphumo edibeneyo yokukhetha okungafanelekanga kweteyipu,

I-Jiangsu Aokai New Material, umenzi okhokelayo we-PTFE welaphu lobushushu obuphezulu, wabelana ngolwazi lobuchwephesha: Imigca ethe tyaba kunye nepateni yelifu umahluko wombala kwilaphu lobushushu obuphezulu be-PTFE ngokubalulekayo kubonakaliswa kobunzima obungalinganiyo bokugquma kunye nokusabalalisa uxinzelelo olungalinganiyo. Ukuvelisa
