ISayensi eNgemva kwe-PTFE yokuNchasa ubushushu
Ulwakhiwo lweMichiza ye-PTFE
Ukumelana nobushushu okungaqhelekanga kwe-PTFE kuvela kulwakhiwo lwayo olulodwa lweekhemikhali. Idityaniswe ngeeathom zekhabhoni kunye nefluorine, i-PTFE yenza ikhonkco eliqinileyo, elinomgca wepolymer. Iibhondi ze-carbon-fluorine zizinzile ngokukodwa, zifuna amandla abalulekileyo ukuze ziqhawuke. Oku kuzinza kwemolekyuli kuguqulela ukuxhathisa ubushushu obuchukumisayo, okuvumela amalaphu agqunyiweyo e-PTFE ukuba agcine ingqibelelo yawo nakubushushu obuphezulu.
IMimandla yeCrystalline kunye neAmorphous
Ulwakhiwo lwe-PTFE luqulathe yomibini imimandla eyikristale kunye ne-amorphous. Iindawo zekristali zinika amandla kunye nokuzinza kwe-dimensional, ngelixa imimandla ye-amorphous inikeza ukuguquguquka. Olu hlobo luntlu-mbini lunegalelo kubuchule be-PTFE bokumelana noluhlu olubanzi lobushushu ngaphandle kokubeka esichengeni iimpawu zayo zomzimba. Njengoko amaqondo okushisa enyuka, isakhiwo sezinto eziphathekayo sitshintsha ngokuthe ngcembe, sivumela ukuba silungelelanise ngaphandle kokusilela ngokukhawuleza. Le propati iphinda isebenze kwi- Teflon i-coated fabric , exhamla kwi-structural stability efanayo.
Indawo yokuBola kweThermal
Ngelixa i-PTFE izingca ngokuxhathisa ubushushu, kubalulekile ukuqonda indawo yayo yokubola. I-PTFE iqala ukuthotywa malunga ne-400 ° C (752 ° F), ikhupha izinto ezinokuba yingozi. Nangona kunjalo, i-PTFE yokwambathisa kumalaphu iqala ukuphulukana nokusebenza kakuhle phambi kwale ngongoma, yiyo loo nto ubushushu bokusebenza obucetyiswayo busezantsi kakhulu. Ukuqonda le mida kubalulekile kusetyenziso olukhuselekileyo nolusebenzayo lwamalaphu agqunywe nge-PTFE kwizicelo ezinobushushu obuphezulu.
Imiba echaphazela iqondo lokuchasa i-PTFE iFabriki eNgqunyiweyo
Izinto ezisisiseko zeFabric
Ukhetho lwelaphu elisisiseko luchaphazela kakhulu ukuxhathisa kobushushu be-PTFE ilaphu eligqunyiweyo. I-Fiberglass yi-substrate ethandwayo ngenxa yokumelana nobushushu obukhoyo kunye nokuzinza komda. Ezinye izinto ezifana ne-aramid okanye i-polyester zinokusetyenziselwa usetyenziso oluthile kodwa ngokubanzi zibonelela ngokuxhathisa ubushushu obuphantsi. I-synergy phakathi kwesiseko selaphu kunye ne-PTFE yokwambathisa imisela imathiriyeli edibeneyo yokusebenza kobushushu bokugqibela.
Ukutyeba kokutyabeka kunye noMgangatho
Ubukhulu kunye nomgangatho we-PTFE yokugquma idlala indima ebalulekileyo ekuxhathiseni ubushushu. Isigqubuthelo esityebileyo sibonelela ngokugquma ngcono kunye nokukhuselwa kubushushu. Nangona kunjalo, akukho malunga nobuninzi kuphela; umgangatho wengubo, kubandakanywa ukufana kwayo kunye nokuthotyelwa kwesiseko, kubaluleke ngokulinganayo. Iingubo zePremium zePTFE ezinemixube ephucukileyo zinokunika ukumelana nobushushu obuphezulu xa kuthelekiswa namabanga aqhelekileyo, ngakumbi kwilaphu eligqunywe ngeTeflon..
Iimeko zokusingqongileyo
Imiba yokusingqongileyo inokuchaphazela kakhulu ukuxhathisa ubushushu be-PTFE amalaphu agqunyiweyo. Ukuvezwa kwimitha ye-UV, iikhemikhali, okanye uxinzelelo lomatshini lunokuthi luthobe udaka ngokuhamba kwexesha, lunciphise ukumelana nobushushu. Ukongeza, ubukho bezinto ezithile okanye ungcoliseko lusenokubangela ukuwohloka kwamaqondo obushushu asezantsi kunokuba bekulindelwe. Ke ngoko, kubalulekile ukuqwalasela yonke imeko yokusebenza xa uvavanya amandla obushushu besixhobo.
