Amashishini osetyenziso lweSilicone eBomvu yoMbhobho woMoya oPhezulu
Imibhobho yomoya ye-silicone ebomvu isetyenziswa kakhulu ekuhambeni kobushushu kunye nemigudu yomoya ye-air conditioners, izixhobo zoomatshini, i-centrifugal fan exhaust air, i-ajenti yobungqina bobumanzi obuqinileyo kwishishini leplastiki, ishishini lombane, ukususwa kothuthu kunye nohlobo lokutsalwa kwezityalo, kunye nokukhutshwa kwesifudumezi. . , Ukukhupha kwi-heater fan kunye ne-welding gas isetyenziselwa ukukhupha izixhobo zegesi, imodyuli yemodyuli, i-chemical fiber process machines kunye nezixhobo, ukunikezelwa komoya oshushu kunye obandayo kunye nenkqubo yokukhupha, kunye nokumisa kunye nabavelisi be-dehumidifier. Izinyibilikisi zendalo ezinganyangekiyo ku-Corrosion, abaqokeleli bomsi kunye nothuli, kunye neeplastiki zegesi, ukupakishwa kunye noshicilelo, ishishini lombane, ukuhamba kobushushu, ukuthuthwa kunye nokukhutshwa kwelindle kwamasuntswana omoya opholileyo, kunye nokugcinwa kunye nokusetyenziswa koomatshini basespacecraft kunye noomatshini bokhuselo kunye nezixhobo ezineemfuno ezizodwa. .
Umbhobho womoya obomvu we-silicone usongelwe embindini wombhobho nge-polyester eyomeleleyo yeplastiki kunye nomgangatho ophezulu wocingo lwentsimbi ehlanganiswe ngobhedu, enodonga olungqingqwa, ukumelana noxinzelelo oluphezulu, ukumelana nokugqwala okuhle, kwaye akulula ukuba kukhukuliswe. Uluhlu lweqondo lokushisa malunga ne-70 ° C ukuya ku-350 ° C, olusetyenziswa kakhulu kwinkqubo yokukhupha igesi eshushu yesithando somlilo esiphezulu sokushisa kunye negesi yokukhupha imoto. Xa ugoba, ubukhulu bodonga akulula ukuba bube yi-concave, kwaye akulula ukwenza i-deformation, ukufumana umgangatho ophezulu kunye nokuthutha, kunye nokumelana nokushisa okungcono.
Umbhobho womoya obomvu obushushu obuphezulu, ogama lakhe langempela "i-silicone ye-air-temperature air duct", luhlobo lwe-air duct eyenziwe nge-glass fiber cloth ehlanganiswe ne-silica gel kunye nenxeba ngentambo yensimbi. Isixhobo sayo esiphambili lilaphu lefiber yeglasi, esekwe kwilaphu elilukiweyo leglasi kwaye ligqunywe ngokuntywiliselwa kwe-polymer anti-emulsion. Ke inokumelana okuhle kwe-alkali, ukuguquguquka kunye namandla aphezulu okuqina. Umnatha wefibre yeglasi ngowona unemesh yeglasi ekwaziyo ukumelana ne-alkali. Yenziwe nge-alkali-free glass fibre yarn ephakathi (inxalenye ephambili yi-silicate, enozinzo oluhle lweekhemikhali) kwaye ijijelwe ngesakhiwo esikhethekileyo-i-leno weave. Emva koko, iphantsi kolawulo lobushushu obuphezulu obufana nesisombululo esichasene ne-alkali kunye nesixhasi. Uluhlu olungaphezulu lwelaphu le-fiber yeglasi lufakwe kwizinto ze-silicone, ukwenzela ukuba xa lusetyenziswe njengentambo yomoya, inokutywinwa, kwaye umoya wokukhupha umoya kunye nokukhupha umoya awuyi kuvuza. Ilaphu lombhobho eliqatywe nge-silicone liqinile kakhulu, kwaye alinamanzi, lingenawo ioli kunye nomlilo.
Njengoko sonke sisazi, uluhlu lokumelana nobushushu bezinto ze-silicone yi--70 ° C ukuya kwiqondo lokushisa eliphezulu malunga ne-300 ° C, ngoko umbhobho womoya ogqunywe nge-silicone unokufikelela kobu bushushu. Kwimarike, abarhwebi badla ngokubhala le mveliso njenge -70°C~350°C. Enyanisweni, ubushushu balo mbhobho womoya awukwazi ukufikelela kwi-280 ° C ixesha elide, kwaye unokufikelela kwi-350 ° C ngokukhawuleza, kodwa ukuba kuthatha ixesha elide, i-air duct iya konakala lula, ngoko ukuze gcina ubomi benkonzo obugqwesileyo. Lo mbhobho we-silicone obomvu wobushushu obuphezulu kufuneka ugcinwe ngaphantsi kwe-280 ° C.
