Ekuqhubekeni kokutya, ukomiswa kwebhetri ye-lithium, kunye namashishini okupakisha, Ilaphu le-PTFE elinobushushu obuphezulu lisetyenziswa ngokubanzi kwizinto zalo ezinganamatheli kunye nokumelana nobushushu. Kodwa yintoni emisela umgangatho kunye nexesha lokuphila kwesi sixhobo? I -substrate.
Njengomenzi welaphu we-PTFE ochwepheshile wobushushu obuphezulu , i-Jiangsu Aokai New Materials icacisa ukuba kutheni ilaphu le-alkali-free fiberglass lelona laphu lihambelanayo. Iimpawu zayo ezikhethekileyo zomzimba kunye neekhemikhali zilungele ngokugqibeleleyo ukugquma kwe-PTFE kunye neemeko zokusebenza ezirhabaxa, ezinikezela ngamandla okudibanisa okuphezulu kunye nokuzinza okupheleleyo.
I-PTFE ine-ultra-low yamandla omphezulu, iyenza kube nzima ukubambelela kwizinto ezininzi. Yiyo loo nto ishishini lisebenzisa i -agent yokudibanisa i-silane njengebhulorho yeemolekyuli - idibanisa ngokwekhemikhali ngelaphu le-fiberglass kwelinye icala kunye ne-PTFE yokwambathisa kwelinye.
Kule nkqubo, ilaphu le-alkali-free fiberglass libonisa izibonelelo ezibalaseleyo:
Ii-anchors ezizinzile kunye nezaneleyo zokubambisana: Umxholo wayo we-sodium oxide (Na₂O) ulawulwa ngokungqongqo ngaphantsi kwe -0.8% . Amaqela e-silanol acocekileyo kwaye azinzile (i-Si-OH) kumphezulu wayo angenza ngokuthe ngcembe iibhondi ze-Si-O-Si zeekhemikhali kunye ne-silane coupling agents.
Ukunqanda umonakalo ophakathi kobuso: Ilaphu le-fiberglass ye-alkali ephakathi iqulethe i-11.9% ~ 16.4% yee-oksidi zesinyithi ze-alkali. Ezi ion zealkali zithatha indawo yokusabela kwaye ngokuqhubekayo ziqhawule amabhondi ekhemikhali enziweyo afana ne-catalysts, ngokulula abangela ukuxobuka kwe-coat - ngakumbi kwiindawo ezishushu nezifumileyo.
'IsiKhokelo esiPheleleyo se-PTFE Coated Fabric' - ukunceda abafundi bakhethe ilaphu elilungileyo kwisicelo sabo esithile.
IiPropati zoMzimba – ezakhelwe iimeko zokuSebenza eziMandundu
Ngaphaya kokubambelela kwikhemikhali ethembekileyo, ezona mpawu zibalaseleyo zomzimba zelaphu le-alkali-free fiberglass iqinisekisa ukusebenza ngokubanzi kwelaphu eligqityiweyo le-PTFE lobushushu obuphezulu :
Uzinzo olugqwesileyo lwe-thermal: I-coefficient yokwandisa i-Thermal ephantsi njenge -1.2×10⁻⁶/℃ , phantse akukho deformation ukusuka -70℃ ukuya kwi-260℃ - ilungele ukudiliza kunye nokuhambisa izicelo ezifuna ukuchaneka okuchanekileyo kwe-dimensional.
Uzinzo oluphezulu lwe-dimensional: Izinga lobude obungaphantsi kwe -0.5% , ukuxhathisa ngokufanelekileyo ukuguqulwa kwe-tensile xa kusetyenziswa njengamabhanti okuhambisa e-PTFE okanye ezinye iimveliso ezithwala uxinzelelo.
Amandla omatshini aphakamileyo: Amandla aphezulu okuqina, ukuqina okuhle, kunye nokuchasana kwempembelelo - kuphucula kakhulu ukuqina kunye nokuqina kwelaphu le-PTFE elinobushushu obuphezulu ukukhusela ukuphuka.
Ukuxhathisa okuqinileyo kwimichiza: Ixhathisa uninzi lweerejenti zeekhemikhali ngaphandle kwe-hydrofluoric acid kunye ne-fosphoric acid eshushu egxininisiweyo-esebenza njengohlaka lwamathambo oluzinzileyo lwemichiza yokuchasa ukubola, ukugxothwa kwerhasi yeflue, kunye nezinye iindawo ezirhabaxa.
Ukugquma kombane okugqwesileyo: Isiqulatho se-alkali yentsimbi ye-oxide esezantsi inika ukusebenza okugqwesileyo kokugquma, oko kuyenza ibe yeyona substrate ikhethwayo kumashishini ombane kunye nombane.
Ukuqukumbela – UKhetho oluPhezulu lweBanga loShishino lwe-PTFE oluPhezulu lweLaphu leTemp
Ukushwankathela, ilaphu le-alkali-free fiberglass libonelela:
I-Chemical: isiseko esizinzileyo sokudityaniswa kobuso, siqinisekisa ukuba i-PTFE yokwambathisa ayiqhubi.
Ngokwasemzimbeni: ukukwazi ukusebenza ngokuzinzileyo phantsi kobushushu obuphezulu kunye nemekobume eyonakalisayo.
Nangona iphezulu kancinci kwiindleko, iingenelo zayo kumandla okubambelela, ubomi benkonzo, kunye nokuthembeka kokusebenza kuyenza ibe yeyona substrate ekhethwa kakhulu kwishishini le-PTFE elinobushushu obuphezulu..
