Ngaphambi kwe-PTFE enamathela, i-resin impregnation, noma i-lamination, Indwangu ye-fiberglass kufanele yomiswe ngaphambili. Injongo ingase ibe ukususa umswakama, noma ingase ihilele ukushiswa kwezinto zokulinganisa izindwangu (i-dewaxing), noma ukufudumala indwangu ibe izinga lokushisa elizinzile ngaphambi kokuyimboza. Inhloso ngayinye idinga izinga lokushisa elihlukile kanye nezilungiselelo zesikhathi.
Imingcele engalungile ingaholela ekukhulelweni okungalungile, ukubumbana okubuthakathaka, ukuphuzi kwendwangu, ukulahlekelwa amandla - noma ngisho nokukhishwa okuphelele.
I-Aokai PTFE inolwazi olunzulu ekucubunguleni ingilazi yefiber. Lo mhlahlandlela uchaza izigaba ezintathu zokwelashwa eziyinhloko, amazinga azo okushisa alungile, ukulawula isikhathi, namathiphu asebenzayo wemiphumela engaguquki.
Izinjongo Ezintathu Zokwelapha Eziyinhloko kanye Nobubanzi Bazo Bezinga Lokushisa
Ukwelashwa Inhloso |
Izinga Lokushisa |
Inhloso Eyinhloko |
Izicelo Ezijwayelekile |
Ukususwa komswakama (okuvamile) |
105°C – 120°C |
Susa amanzi adsorbed ngaphandle kokulimaza ama-sizing agents |
Lamination, PTFE/silicone coating, prepreg layup |
I-Dewaxing / ukuhlanza okushisayo (ukususwa kosayizi) |
300°C – 450°C |
Shisa ngokuphelele usayizi wendwangu (isitashi, i-PVA, njll.) |
Izinqubo ezidinga indawo ehlanzekile kakhulu: ukufakwa kwe-resin, ukwelashwa ngamakhemikhali |
Ukushisa kwangaphambi koshintsho lwenqubo |
60°C – 100°C |
Phakamisa izinga lokushisa lendwangu yokumboza noma ukumilisa |
Imigqa yokugqoka eqhubekayo, ngaphambi kwamathangi e-glue dip; ivimbela ukukhuphuka kwe-resin viscosity kusuka kwendwangu ebandayo |
Ukususwa Komswakama Okuvamile - Inqubo Evame Kakhulu
Lesi yisinyathelo esijwayelekile sangaphambi kokumiswa kwendwangu eminingi ngaphambi kokumbozwa noma ukucwiliswa. Umgomo uwukukhipha umswakama ngokuphelele kuyilapho uvikela ama-sizing agents abamba imicu ndawonye.
1. Ukulawula izinga lokushisa
Ezindwangu ezijwayelekile zikagesi neziqinisayo: gcina u-105°C - 120°C.
Ezindwangu eziphathwa nge -silane coupling agents : gcina izinga lokushisa lingaphansi kuka-110 ° C ukuze ugweme ukuphula izibopho zokuhlanganisa.
Ukuchezuka kwezinga lokushisa ngaphakathi kuhhavini kufanele kulawulwe ku- ±5°C ukuze kuvinjelwe ukushisa kwasendaweni.
2. Ukulawula isikhathi (ngokusekelwe esisindweni sendwangu)
Isisindo Sendwangu |
Isikhathi Esinconyiwe |
Indwangu ezacile (<100 g/m²) |
10 - 15 imizuzu |
Indwangu emaphakathi futhi esindayo (200 – 400 g/m²) |
20 - 30 imizuzu |
Indwangu ewugqinsi / umata (>600 g/m²) |
1 - 2 amahora noma ngaphezulu |
Umbandela wokunqamula: Isisindo esiqhubekayo sifinyelelwa uma umehluko wesisindo phakathi kwezilinganiso ezimbili ezilandelanayo ungaphansi kuka-0.1%. Ezindwangu ezigoqiwe, zilengise ngokukhululekile noma sebenzisa imichilo yesikhala ngesikhathi somiswa ukuze ugweme inkinga yengaphandle elomile kodwa ingaphakathi elimanzi.
3. Amaphuzu okulawula abalulekile
Ihhavini kumele libe nokususwa komswakama okuphoqelekile . Vula ama-valve omoya omusha ukuze ukhiphe umoya omswakama ngesikhathi.
Ungalayishi kakhulu ihhavini; qinisekisa ukugeleza komoya eduze komqulu ngamunye noma ishidi.
I-Dewaxing kanye Nokuhlanza Okushisayo - Kwezindawo Ezihlanzekile Kakhulu
Lapho indwangu kufanele ingabi nazo ngokuphelele izinto ezilinganisa izinto eziphilayo (isb, ngaphambi kokufakwa kwenhlaka esebenza kahle endaweni yendiza noma izinhlanganisela ezishisa kakhulu), ukuhlanzwa okushisayo kuyadingeka.
1. Ukulawula izinga lokushisa
Isigaba sokushisa nesokubhema: cishe ku-300°C. Idinga umoya-mpilo owanele kanye nokukhipha intuthu okusebenzayo.
Isigaba sokutubeka kwezinsalela: kancane kancane nyusa izinga lokushisa libe ngu- 380°C – 450°C futhi ubambe, ukuze ukhiphe ngokugcwele ikhabhoni eyinsalela.
Ungalokothi udlule ku-500°C - ngaphandle kwalokho i-fiberglass ngokwayo izoba brittle futhi ilimale.
2. Ukulawula isikhathi
Ngezithando zokushisa ezishisayo eziqhubekayo, lungisa isivinini sokusebenza kwendwangu ukuze uqinisekise ukuthi indwangu ihlala endaweni enezinga lokushisa eliphezulu imizuzu embalwa ukuya kwengaphezu kweshumi, kuye ngesisindo sendwangu. Izindwangu ezisindayo zidinga ukuchayeka isikhathi eside.
3. Indlela yokwamukela
Ukulahlekelwa ekushiseni (LOI) kuzoba ngaphansi kuka-0.1%. Leli izinga legolide.
Ukuhlolwa kwenkambu elula: Base ikhona lendwangu ngesilawuli. Izinto ezifanelekile azikhiqizi intuthu emnyama noma iphunga elingavamile, elinezinsalela zomlotha ezincane.
Indwangu efanelekayo ibonakala imhlophe noma igcina umbala wayo wangempela, ngaphandle kwamabala amnyama noma imicu ephuzi.
4. Amanothi okulandelela
Indwangu ye-fiberglass ene-dewax inomsebenzi ongaphezulu . Kudlulisele enqubweni yokumilisela elandelayo ngokushesha, noma vala futhi upakishe kahle ukuze uvimbele ukumuncwa kabusha komswakama nokungcoliswa.
Ukushisa Ngaphambi Kokumboza - Ukuze Uzinze Kwenqubo
Ngaphambi kokufaka i-PTFE emulsion noma i-silicone yenjoloba enamathelayo, indwangu ingase idinge ukushisisa kwangaphambili okumnene ekushiseni okuzinzile.
1. Imingcele yokushisa
Setha izinga lokushisa: 60°C – 80°C , ngaphezudlwana kwendawo yamazolo ukuze ugweme ukomiswa okushesha ngokweqile kwezindwangu.
Isikhathi sokuhlala: ngokuvamile amasekhondi amaningi ukuya kumzuzu owodwa noma emibili ngokusebenzisa amahhavini we-infrared webanga elifushane noma omoya oshisayo - okwanele ukuletha indwangu ezingeni lokushisa eliqondiwe.
2. Iziqondiso zokusebenza ezisebenzayo
Thatha izinga lokushisa langempela lendwangu njengento evamile, hhayi izinga lokushisa lomoya kahhavini. Sebenzisa amathemometha e-infrared noma amadivaysi okulinganisa izinga lokushisa ahambisana nawo ukuze uqaphe ngesikhathi sangempela.
Ukugeleza komoya okulinganayo nokujikeleza - ukuhanjiswa komoya oshisayo kunquma ukusebenza kahle kokumisa. Isivinini somoya esilinganayo siqinisekisa ukusatshalaliswa kwezinga lokushisa kulo lonke ububanzi bendwangu.
Uhlolo lwesampula lokuqala: Amaqoqo ahlukene angasebenzisa ama-ejenti okulinganisa ahlukene. Thatha amasampula amancane uwasule emazingeni okushisa ahlukene (105°C, 120°C, 130°C, njll.). Bheka ukuguquguquka kombala nokushintsha kwamandla ukuze uqinisekise izinga lokushisa eliphezulu eliphephile leqoqo ngalinye.
Isitoreji Ngemva Kokomisa - Vimbela Ukungcoliswa kabusha
Indwangu eyomile, ikakhulukazi i-dewax, i-hygroscopic futhi ingcoliswa kalula.
Uma kungenjalo ukuze usetshenziswe ngokushesha, vala izikhwama ze-aluminium foil ezinama-desiccant.
Okunye: gcina endaweni yokomisa izinga lokushisa elingaphansi kuka-30°C kanye nomswakama ongaphansi kuka-40%.
Iwindi lokusetshenziswa elinconyiwe: phakathi kwamahora angu-4 kuya kwangu-8 ngemva kokumiswa ukuze uthole imiphumela ehamba phambili. Ngaphandle kwalokho, yome kabusha ngaphambi kokusetshenziswa.
Ithiphu ye-Aokai PTFE: Kuzinhlelo zokusebenza ezinokwethenjelwa okuphezulu (izinhlanganisela ze-aerospace, ukufakwa kwamandla kagesi aphezulu), sincoma ukusebenzisa indwangu ngokushesha ngemva kokoma noma phakathi namahora angu-2.

I-Aokai PTFE inikeza ukucaciswa kokumiswa kwangaphambili kwazo zonke izindwangu zethu ze-fiberglass. Ngezinhlelo zokusebenza ezibucayi, singahlinzeka ngendwangu eyomiswe ngaphambili futhi evalwe nge-vacuum elungele ukusetshenziswa ngokushesha. Xhumana nathi ukuze uthole imingcele yokomisa ngokwezifiso ngokusekelwe ohlotsheni lwendwangu yakho kanye nenqubo elandelayo.
Okuqukethwe okungenhla kunikezwa ngu I-Jiangsu Aokai New Materials Technology Co., Ltd.
Uma ufisa ukwazi okwengeziwe mayelana nokucaciswa okuningiliziwe, izimo zohlelo lokusebenza nezixazululo ezenziwe ngokwezifiso zohlu oluphelele lomkhiqizo wethu, okuhlanganisa izindwangu ze-PTFE ezishisa kakhulu, amateyipu we-PTFE, amabhande anezikhala we-PTFE, amabhande omshini wokubopha angenamthungo, indwangu ye-PTFE enohlangothi olulodwa, amabhande angamelana nokushisa okuphezulu, namabhande avikela ingilazi aphezulu:
Sihlala sisekela ifilosofi yobungcweti nobuqotho, futhi sizibophezele ekukunikezeni izisombululo eziphuma endaweni eyodwa kanye nezinsizakalo ezicatshangelwayo.
