Ukuba ukhe walisonga iqhekeza le PTFE-coated fiberglass ilaphu kabukhali, mhlawumbi ubone umgca crease emhlophe ivela ngoko nangoko. Songa kwakhona kwakwindawo enye, kwaye ilaphu lisenokukrazuka.
Oku ayisosiphene - yindlela yokuziphatha yendalo yemathiriyeli. Ilaphu le-PTFE elinobushushu obuphezulu ligqwesa ekuxhathiseni ubushushu, iikhemikhali, kunye nokuncamathela, kodwa ukuxhathisa okuthambileyo (ukunyamezela ukusonga okuphindaphindiweyo) yeyona propati ibuthathaka yomatshini.
I-Aokai PTFE ivavanye ubomi obuguquguqukayo kubo bonke ubungqingqwa kunye nokwaluka. Eli nqaku lichaza ukuba kutheni ilaphu ligotywa kakubi, liyithelekisa nezinye izinto, kwaye linika iindlela ezisebenzayo zokusebenzisa umda.
Kutheni le nto i-PTFE Fabric inoNxaso olubi lweFleksi?
Oyena nobangela yi- fiberglass substrate , hayi i-PTFE yokwambathisa.
1. I-Fiberglass - yomelele kodwa i-brittle
Iintsinga zeglasi zinamandla aphezulu kakhulu okuqina kodwa ubude obuphantsi kakhulu ngexesha lekhefu (ngokuqhelekileyo yi-2-4%). Xa igobile ngokuphindaphindiweyo, imicu nganye idinwa kwaye iqhekeke. Emva kokuba iifayibha ezimbalwa ziphule, uxinzelelo lugxininise kwizinto ezisele, ezikhokelela ekusasazeni ngokukhawuleza - iingubo zikrazula ngokulula.
2. PTFE ukutyabeka – isithinteli esilinganiselweyo
Umaleko we-PTFE uthambisa imicu yefiber, unciphisa ukungqubana kwangaphakathi kunye nokuphucula kancinane ukunyameka. Nangona kunjalo, ayikwazi ukuphelisa ubuqhophololo beglasi. Ilibazisa kuphela ukugqabhuka kwefayibha ngomda omncinci.

I-key takeaway: I-PTFE-coated fiberglass ihlala kumbindi-ukuya-phantsi ekupheleni phakathi kwamalaphu anobushushu obuphezulu okumelana nokuguquguquka. Kungcono kuneglasi engenanto kodwa kubi kakhulu kunefilimu ecocekileyo ye-PTFE.
Izinto eziphambili ezichaphazela ukuxhathisa kweFlex
1. Ukutyeba - eyona nto ibaluleke kakhulu
Ukutyeba |
Engqinisiso Songathwa Endurance |
Imo Yokusilela |
0.08mm |
Amakhulu ukuya kwi ~1,000 ukugoqa |
Ukuqhekeka kancinci kancinci |
0.13mm |
Iidozini ukuya kumakhulu ambalwa |
I-white crease emva kokugoba okubukhali |
0.25mm nangaphezulu |
Ubuninzi bokugotywa - ukuqhekeka okubonakalayo ngaphakathi kwemijikelo ye-50 |
Ukuqhekeka okuncinci, ukugquma i-delamination |
Umthetho wobhontsi: Amalaphu abhityileyo aguquka ngcono. Kwizicelo ezifuna ukugotywa okuphindaphindiweyo, khankanya ibakala elincinci elihlangabezana nezinye iimfuno zakho (amandla, ubushushu).
2. Ukwakhiwa kwe-weave
I-Satin weave - ukudada okude kuvumela ukuba imisonto ityibilike kancinci, isasaze uxinzelelo olugobayo. Ubomi obuguquguqukayo obungcono kunokwaluka nje.
I-Plain weave - iindawo ezinqamlezileyo eziqinileyo zokutshixa imisonto; Uxinzelelo lugxile kwiindlela zokuhlangana. Ukuxhathisa okubi ngakumbi.
3. Ubushushu bokusebenza
Kubushushu obuphezulu (200-260 ° C), i-PTFE yokwambathisa iyathamba, kwaye amandla omatshini e-fiberglass ayancipha. Oku kwenza kube mandundu ngakumbi ukuxhathisa ukudinwa. Ukuba isicelo sakho sibandakanya ubushushu obuphezulu kunye nokugoba rhoqo, lindela ubomi obufutshane.
4. Iradiyasi yokugoba
Irediyasi enkulu = ubomi obude. I-creasing ebukhali (i-radius <1mm) yenza imigoqo efileyo kunye nokwaphuka kwefiber ngoko nangoko. Kwiirola ezikhokelayo, sebenzisa eyona dayamitha yepraktikhali enkulu. Njengesikhokelo esirhabaxa, ubuncinci be-roller ububanzi obucetyiswayo yi-10-20x ubukhulu belaphu.
Idatha yovavanyo lwangaphakathi (Aokai PTFE) : Kuba 0.13mm satin weave ilaphu, ukugoba phezu 10mm mandrel iphumelele 500-800 imijikelo phambi kokuqhekeka ebonakalayo. Ngaphezulu mandrel 5mm, imijikelo lehla ukuya 100-150. Ngaphezulu kwe-2mm mandrel (i-crease ebukhali), ukusilela kwenzeka ngaphakathi kwe-20 imijikelo.
Iingcebiso eziSebenzayo zokuSebenza
Ukuba isixhobo sakho sifuna ukugoba rhoqo-okunje:
Amabhanti e-high-frequency welder drive
Iibhanti zoxinzelelo ezijikeleza iipuli ezincinci
Ukudiliza amabhanti okuhambisa ngokujika okubukhali
Uneendlela ezintathu ongakhetha kuzo:
1. Ukhetho loku-1 – Lungiselela ukhetho lwelaphu le-PTFE ngaphakathi kwemida yalo
Khetha amabanga amancinane (0.08mm ukuya ku-0.13mm) kulawo anzima
Ukhetha ukuluka kwesatin kunokwaluka nje
Cela idatha yovavanyo lwe-MIT flex kumthengisi wakho (ASTM D2176 okanye efanayo)
Uyilo lwerediya enkulu yokugoba kuyilo lomatshini
Yamkela ilaphu le-PTFE njengento etyiwayo - isicwangciso sokutshintshwa kwamaxesha athile (rhoqo kwiinyanga ezimbalwa kuxhomekeke kubalo lomjikelo)
2. Indlela yesi-2 – Tshintshela kwifilim eyomeleleyo ye-PTFE
Ifilimu ye-PTFE ecocekileyo (skived) inokuxhathisa okungaqhelekanga. Nangona kunjalo, ayinayo i-fiberglass yokuqinisa, ngoko inamandla angaphantsi kunye neenyembezi ngokulula phantsi koxinzelelo. Ifanelekile kwi-light-duty, izicelo zokugoba eziphantsi.
3. Inketho yesi-3 - Sebenzisa i-aramid okanye enye ilaphu le-organic fiber
I-Aramid (umzekelo, i-Nomex) okanye ilaphu le-PPS eligqunywe nge-PTFE linika ubomi obuguquguqukayo obungcono kunelaphu le-PTFE esekwe kwiglasi. I-trade-off: ukunciphisa ukunyanzeliswa kokushisa okuqhubekayo (ngokuqhelekileyo ≤200 ° C) kunye neendawo ezahlukeneyo zomhlaba. Kwizicelo ezingaphantsi kwe-200 ° C kunye nokugoba okukhulu, qwalasela ezi ndlela.
I-Aokai PTFE yenza ilaphu le-aramid eligqunywe nge-PTFE xa liceliwe. Qhagamshelana nathi malunga nobushushu kunye nedatha ye-flex.
Isishwankathelo – Yazi imida, Yila Ngokufanelekileyo
Ilaphu le-PTFE lobushushu obuphezulu lime kakuhle ngokuchasene noxinzelelo, ubushushu obuphezulu (260°C), kunye nohlaselo lwekhemikhali. Kodwa ukunganyangeki kwayo sisithintelo sokwenyani. Ayinakumelana nokusongwa okubukhali okuphindaphindiweyo njengamabhanti erabha okanye ifilimu ecocekileyo ye-PTFE.
Yisebenzise apho ukugoba kuthambile okanye kunqabile.
Apho ukugoba okubukhali okanye rhoqo kungenakuthintelwa, yiya kuncipha, sebenzisa i-satin weave, yonyusa iradiyasi yokugoba, okanye utshintshe imathiriyeli.
I-Aokai PTFE ibonelela ngedatha yovavanyo oluguqukayo kuwo onke amabakala ethu zelaphu. Sinokukunceda ukhethe ubukhulu obufanelekileyo kunye nokuluka kwiimfuno zokugoba zesicelo sakho.
Umxholo wobugcisa onikezelwe ngu I-Jiangsu Aokai yeZixhobo eziNtsha zeTekhnoloji Co., Ltd.
Ukufumana iinkcukacha ezithe kratya kunye nezisombululo zesiko le-PTFE ngelaphu lobushushu obuphezulu, iteyiphu, ibhanti elinomnatha, ibhanti lokufunxa, kunye nokunye:
Sibambelela kubuchwephesha kunye nemfezeko, sibonelela ngezisombululo zemizi-mveliso enye.
