Ingaba i-PTFE iHlenze njani iFabric yoBuqondo obuPhezulu boTshothuko lweThermal?

Kwiinkqubo ezininzi zemizi-mveliso, Ilaphu le-PTFE alivezwa kubushushu obuzinzileyo. Ifumana utshintsho olukhawulezayo lobushushu - ukusuka kwisikhenkcisi ukuya kwi-oveni, ukusuka kumatshini oshushu ukuya kumoya ojikelezayo, okanye ukusuka kwisitywini sobushushu ukuya kwindawo epholileyo. Oku kubizwa ngokuba yi -thermal shock.

Umbuzo ngulo: ingaba ilaphu le-PTFE lobushushu obuphezulu liyakwazi ukuphila ngokuphindaphindiweyo, ukuguquka kobushushu obukhawulezayo ngaphandle kokuqhekeka, ukudityaniswa, okanye ukuphulukana nokusebenza?

Impendulo ixhomekeke kuluhlu lobushushu. Ngaphakathi kwemida yayo yokusebenza eqhelekileyo, ilaphu le-PTFE lisebenza kakuhle kakhulu. Kodwa yityhale kakhulu, kwaye isambatho siya kusilela.

I-Aokai PTFE ivavanye ukuxhathisa ukothuka kwe-thermal kulo lonke uluhlu lwemveliso yethu. Esi sikhokelo sichaza ukuba yeyiphi imilinganiselo yobushushu ekhuselekileyo, indlela esebenza ngayo imathiriyeli, kwaye yintoni omele uyiphephe.

Uluhlu loMahluko woBubushushu obunyamezelekayo-Yintoni eKhuselekileyo?

1. Uluhlu oluqhelekileyo lokusebenza (-70 ° C ukuya ku-260 ° C)

Ukuhamba ngebhayisikile ngokukhawuleza kweqondo lokushisa ngaphakathi kolu luhlu akuyi kubangela umonakalo ocacileyo kwilaphu. Imeko yesicelo eqhelekileyo ibandakanya ukutshintsha rhoqo phakathi kogcino olubandayo kwi -50°C kunye nesixhobo sokucinezela okushushu kwi-260°C. Izinto eziphathekayo ziyakwandisa kunye neekontraka, kodwa i-PTFE yokugqoka ihlala ilungile kwaye i-fiberglass substrate ayifuni.

Umzekelo wokusetyenziswa: Isixhobo sokumisa umkhenkce apho ibhanti litshintshana phakathi komkhenkce onzulu (-40°C) kunye ne-oven yokomisa (150°C). Ilaphu le-PTFE liyiphatha yonke imihla.

2. Umahluko omkhulu wobushushu (malunga ne-250°C delta)

Amalaphu ePremium PTFE anokumelana nomothuko onzima wobushushu - umzekelo, ukuntywiliselwa kwangoko kwi-10 ° C kumanzi abandayo emva kokuvezwa kwi-260 ° C (i-250 ° C drop). Ukwaleka akuyi kugqabhuka okanye kucime emva kwemijikelo ephindaphindiweyo. Oku kuye kwaqinisekiswa ngovavanyo lwe -Aokai PTFE .

3. Indawo eyingozi – ngaphezu kwama-300°C

Umngcipheko womonakalo uyenyuka ngokukhawuleza ukuba umahluko wobushushu uyanda ngakumbi, njengokupholisa ngokukhawuleza kumaqondo obushushu angaphezu kwama-300°C. Nje ukuba ilaphu ligqithe kuma-300°C (kufutshane nenqanaba lokunyibilika le-PTFE lika-327°C), i-coating iba semi-enyibilikisiweyo kwaye ibuthathaka ngoomatshini. Ukupholisa ngesiquphe ke kubangela ukushwabana okukhulu kunye nokuqhekeka.

UmGaqo wokuSebenza – i-Substrate vs. Ukwaleka

Ukusebenza kokutshatyalaliswa kwe-thermal kuchongwa ziipropati ezihambelanayo ze-fiberglass substrate kunye ne-PTFE yokugqoka.

1. I-Fiberglass substrate - umqolo ozinzileyo

• Indawo yokuthamba ngaphezulu kwama-800°C

• I-coefficient ephantsi kakhulu yokwandiswa kwe-thermal (malunga ne-5 × 10⁻⁶/°C)

• Ukungahambi kakuhle kwe-thermal

Ezi mpawu zithetha ukuba imicu yeglasi ayinwebeki okanye icuthene kakhulu nobushushu. Bagcina imilinganiselo ezinzileyo phantsi kokutshatyalaliswa kwe-thermal kwaye baxhathise ukunyanzeliswa koxinzelelo ngokufanelekileyo. I-substrate ayilona ikhonkco elibuthathaka.

2. PTFE ukutyabeka – into ethintelayo

• I-Coefficient yokwandiswa kwe-thermal malunga ne- 30 ukuya kwi-40 amaxesha e-fiberglass (100-150 × 10⁻⁶ / ° C)

• Ngexesha lokufudumeza ngokukhawuleza kunye nokupholisa, i-coating iyanda kwaye inkontileka iyancipha kakhulu kune-substrate

• Oku kuvelisa uxinzelelo olukhulu kwi-bonding interface

Kutheni isasebenza: I-PTFE yokwambathisa ibhityile (ngokuqhelekileyo i-10-30 μm) kwaye iguquguquka. Inkqubo yokufakwa ibophelela ngokuqinileyo kwi-fiberglass. Ngaphakathi kweqondo lokushisa eliqhelekileyo, i-coating inokwelula kwaye ihlaziye ngaphandle kokuqhekeka. Kwiqondo lokushisa eligqithisileyo okanye ngokuveliswa kakubi, uxinzelelo ludlula amandla okugquma.

Inqaku le-Aokai PTFE: Ilaphu lethu le-premium-grade lisebenzisa iipasi ezininzi zokungena, ezivumela i-PTFE ukuba ingene nzulu kwi-fiberglass weave. Oku kudala 'i-anchor' yomatshini echasene ne-delamination ngexesha lokuhamba ngebhayisikile ye-thermal - umahluko ophambili kwiingubo ezisezantsi ezihlala phezulu kuphela.

Imiba ephambili echaphazela ukuxhathisa i-Thermal Shock

Ayingawo onke amalaphu ePTFE alinganayo. Izinto ezintathu zimisela ukuba imveliso ethile imelana kangakanani nokuhamba ngebhayisekile eshushu.

1. Itekhnoloji yokuvelisa - imiba yomgangatho wokufakelwa

Amalaphu akumgangatho ophezulu angena kwiinkqubo ezininzi zokufakelwa kunye ne-sintering . I-PTFE ingena nzulu kwizikhewu zefiber, zenza ulwakhiwo oluqinileyo lweankile. Oku 'kutshixiwe-ngaphakathi' kwibhondi iyaxhathisa i-delamination ngexesha lokothuka kwe-thermal.

Iimveliso eziphantsi zisebenzisa i-coating eyodwa-pass. I-PTFE ihlala kumphezulu kuphela. Ngaphantsi kokutshintsha kobushushu obukhawulezayo, i-coating iyaxobuka njengesitika esixekileyo.

2. Ubunzima bokugquma - ubhityile ungcono

Iingubo ezinqabileyo zilungelelanisa ngcono ukuguqulwa kwe-substrate. I-5-10 μm yokugqoka iya kulungelelanisa kunye nemicu yeglasi. I-30-50 μm yokugquma iqinile kwaye iyakwazi ukuqhekeka.

3. Ibakala le-Substrate - i-dense weave, i-filaments ephezulu yamandla

Amalaphu ashinyeneyo alukiweyo, aphezulu amandla e-filament fiberglass ane-void ezimbalwa kunye nozinzo olungcono lwe-dimensional. Bakwabonelela ngommandla ongaphezulu womphezulu we-PTFE anchoring. Amalaphu akumgangatho ophantsi, awalukiweyo avulekileyo athandeka ngakumbi kwi-edge fray kunye nelahleko yokugquma phantsi kwebhayisekile eshushu.

Ukuqina kwizicelo eziSebenzayo-Yintoni omele uyilindele

Kwizixhobo ezifuna ukufudumeza okuphindaphindiweyo kunye nokupholisa, njenge:

• Izitywini zobushushu (umjikelezo rhoqo kwimizuzwana embalwa)

• Iiphedi zokwahlula ezicinezelayo ezishushu

• Izinto zokukhusela i-welding

• Isixhobo sokuhamba ngebhayisekile sokukhenkceza

Amalaphu ePremium PTFE anobushushu obuphezulu anokunyamezela amashumi amawaka emijikelo ye-thermal ngaphandle kokusilela.

1. Indlela okwenzeka ngayo ukungaphumeleli - ukudinwa ngokuthe ngcembe

Ukusilela akukhawulezi. Iyenzeka inyathelo ngenyathelo:

1. I-Micro-cracks ikhula kwi-PTFE yokugquma (engabonakali ngeso lenyama)

2. I-Coating iqala ukulahlekelwa yipropati engabonakaliyo kwiindawo ezigxininisiweyo

3. I-Edge peeling ibonakala kwiindawo eziqhekekileyo okanye ezisikiweyo

4. Ukwambathisa delaminates, eveza fiberglass

5. I-Fiberglass frays kunye neenyembezi zelaphu

Ukuhlola rhoqo (rhoqo kwimijikelo engamawaka ambalwa) kunokubona ukuqhekeka kwangethuba ngaphambi kokusilela okuyintlekele.

Amanqaku osetyenziso kunye neMigibe eqhelekileyo-Yintoni emayithintelwe

Nditsho nelaphu elingcono le-PTFE linokutshatyalaliswa ngokusebenza okungafanelekanga.

1. Ungaze uphole ngokukhawuleza kumaqondo obushushu agqithisileyo (>300°C)

Ukuba ilaphu lifudunyezwe ngaphezu kwe-300 ° C (kufuphi neqondo lokunyibilika lika-327 ° C) kwaye lipholiswe ngokukhawuleza (umzekelo, ukucinywa emanzini okanye nokuba kuvezwa nje kwiqondo lokushisa lomoya), i-PTFE yokugqoka iya kuncipha kakhulu kwaye ingaqala ukubola. Oku kubangela ukuqhekeka, ukuxobuka, kunye nomonakalo ongunaphakade . Lo msebenzi kufuneka uthintelwe ngokungqongqo.

Umda wokhuseleko: Kubomi obude, gcina ubushushu belaphu bungaphantsi kwama-260°C. Uhambo olufutshane ukuya kwi-280-300 ° C luyanyamezeleka kwamanye amabanga, kodwa aluze luyothuke luphole kuloo maqondo obushushu.

H3: Gcina kude kwizinto ezibukhali kunye nokugoba ngokugqithisileyo

Ukutshatyalaliswa kwe-Thermal kudibaniswa nomonakalo womatshini - njengama-creases, ama-scratches, okanye ama-folds abukhali-kukhawulezisa ukuwohloka. Ingubo ekrweliweyo sele ibuthathaka; ibhayisekile ye-thermal ke isasaze iintanda ukusuka ekuqaleni.

Ukuziqhelanisa kakuhle: Lihlole ilaphu rhoqo. Faka enye indawo xa ubona imikrwelo ebonakalayo, amanqaku okukrazuka, okanye ukunyuswa komphetho phambi kokuba kuqhubeke ibhayisekile eshushu.

IsiShwankathelo – IziKhokelo ze-Thermal Shock ye-PTFE Fabric

I-Aokai PTFE yenza ilaphu leprimiyamu ye-PTFE yobushushu obuphezulu elinamapasi amaninzi okufakelwa kunye neengubo ezibhityileyo, ezibhetyebhetye ezilungiselelwe ukuxhathisa ukothuka kwe-thermal. Ukulungiselela usetyenziso olunobushushu obugqithisileyo bebhayisikile (umzekelo, ukupholisa ngokukhawuleza ukusuka kwi-260°C), qhagamshelana nathi ngedatha yovavanyo oluthile kunye nezincomo zebakala.

Lo mxholo ungentla unikwe ngu I-Jiangsu Aokai yeZixhobo eziNtsha zeTekhnoloji Co., Ltd.
