Indwangu ye-PTFE ephezulu yokushisa (i-PTFE-coated fiberglass) inhle kuphela njengezinto zokusetshenziswa ezisetshenziselwa ukuyenza. Izingxenye ezimbili ezibalulekile: i- PTFE resin/emulsion (i-coating) kanye ne- fiberglass substrate (i-reinforcement). Ukungcola kunoma yikuphi - ama-ion ensimbi, ama-polymers anesisindo esiphansi, ama-agent asele, noma ama-alkali oxides - kungabangela ukwehluleka ngaphambi kwesikhathi: ukuphuzi, ukuqhekeka, ukulahlekelwa kokungathungi, ukubola, noma ukuhlukaniswa kwe-insulation.
I-Aokai PTFE isebenzisa izinto ezingavuthiwe ezihlanzekile kakhulu kanye nokulawula inqubo eqinile. Lo mhlahlandlela uchaza ukuthi ubumsulwa buthinta kanjani ubukhulu bokusebenza ngakunye nokuthi kungani bubalulekile ezicelweni ezifunayo.
I-PTFE Raw Material Purity - Yikuphi Ukungcola Okukhona?
Ukungcola okujwayelekile ku-PTFE kufaka phakathi:
Ama-monomers angaphenduliwe kanye nama-polymer anesisindo esiphansi se-molecular
Abaqalisi abayizinsalela nabahlakazayo (isb., PFOA)
I-ion yensimbi (i-iron, ithusi, i-sodium)
Izinsiza zokucubungula kanye nemikhiqizo
Ukuhlanzeka okuphezulu kwenza okokusebenza kukwazi ukuletha ukusebenza eduze nezicaciso ezifanele.
1. Ukumelana nokushisa nokuzinza kokushisa
Ama-ion ensimbi (i-ayoni, ithusi, i-sodium) asebenza njengezisusa eziqinile zokuwohloka kokushisa kwe-PTFE . Ngaphansi kwesevisi yesikhathi eside engaphezu kuka-260°C, ngisho nokulandelela ukungcola kwensimbi kusheshisa ukuphuka kweketango lamangqamuzana, okubangela ukufiphala ngaphambi kwesikhathi nokuqhekeka. I-High-purity PTFE ifaka izinga lokushisa eliphezulu lokubola okushisayo, ihlala imhlophe qwa, futhi imelana nokubaphuzi ngempumelelo.
Ama-polymer anesisindo esiphansi se-molecule kanye nemikhiqizo ephuma ku-oily ithuthela endaweni enamathelayo ngesikhathi sokushiswa kwezinga lokushisa eliphezulu, yenze imvula.
Impahla engelona induku eyonakele: Ingaphezulu liba lukhuni futhi lijwayele ukunamathela ezintweni ezigayiwe (ukudla, amateyipu okunamathela).
Ingcuphe yokungcola: Ezingeni lokudla nezicelo zezokwelapha, imvula efudukayo ingase ingcolise imikhiqizo futhi yehluleke kumazinga enhlanzeko. Ukuhlanzeka kuyinkomba eyinhloko yezindwangu ze-PTFE ezithinta ukudla.
Ama-ion angcolile (ama-metal cations, ama-halogen ions) asebenza njengabathwali bokushaja, anciphisa kakhulu ukumelana nevolumu kanye ne-voltage yokuwohloka. Ezingenile eziphakeme (isb., ama-gaskets afaka ugesi), ukuhlanzeka kwempahla eluhlaza kubalulekile. Izimbotshana ezibangelwa ukungcola zingase ziholele ekuphumeni kancane.
4. Ukumelana namakhemikhali nokuhlangana
Ukungcola okuncibilikayo kuyaphuma lapho kuvezwe emithonjeni yamakhemikhali, kushiye ama-micro-pores ngaphakathi kwengubo. Lezi zinkinga zivumela igesi ebolayo kanye noketshezi ukuthi kungene futhi kucekele phansi i-fiberglass substrate, kubukela phansi ukusebenza komgoqo wendwangu.
I-Fiberglass Substrate Purity - Izindaba Zokuqukethwe kwe-Alkali
I-Fiberglass ayiyona i-silicon dioxide ehlanzekile. Ukwakheka kwayo kwamakhemikhali kuchaza ukumelana nokushisa, amandla emishini, kanye nokuhlangana ne-PTFE.
1. Okuqukethwe kwe-alkali metal oxide - isici esinqumayo
Uhlobo lwe-Fiberglass |
Na₂O + K₂O Okuqukethwe |
Izici |
Ingilazi ye-E (i-alkali-free) |
<0.8% |
Ukuhlanzeka okuphezulu, ukwahlukanisa ugesi okuhle kakhulu, ukuncipha kwamandla kancane emazingeni okushisa aphezulu - indinganiso yendwangu ye-PTFE |
Ingilazi ye-alkali ephakathi |
~12% |
Izindleko eziphansi, ukumelana nokushisa okubi, amandla ehla kakhulu emazingeni okushisa aphezulu |
Ingilazi ye-alkali ephezulu |
>15% |
Iyancipha ngokushesha ngaphansi kokushisa; I-alkali ions yenza ukubola kwe-PTFE |
Emazingeni okushisa aphezulu, ama-ion ensimbi e-alkali asuka engilazini ene-low-purity awagcini nje ngokwenza indwangu ngokwayo ibe buthaka kodwa futhi abangele ukuwohloka kwe-PTFE coating , kusheshisa ukwehluleka kukonke. Ukwengeza, ingilazi ephakathi/phezulu-ye-alkali imunca umswakama, ibangele ukumelana nokushisa kwehle kakhulu.
2. Izithako zokulinganisa - okunye ukungcola
Ama-sizing agents (isitashi, i-PVA, uwoyela) asetshenziswa ngesikhathi sokwelukwa kwe-fiberglass ukuvikela imicu. Uma ingasuswanga ngokuphelele ngaphambi kokunameka kwe-PTFE, i-organics eyinsalela ikhabonize, ibole, futhi ifake igesi phakathi ne-sintering cishe ku-400°C.
Ukonakala kwendawo: Ukushintsha umbala ophuzi, amachashaza amnyama, amabhamuza - imikhiqizo iyehluleka ukuhlola ukubukeka.
Ukuhlangana okubuthakathaka kobuso obuhlangene: Izinsalela zekhabhoni zivimba amakhemikhali nokunamathisela okubonakalayo phakathi kwe-PTFE ne-fiberglass, okubangela ukubola, amabhamuza, nokuxebuka phakathi nesevisi.
3. Ukumelana nokukhathala okuguquguqukayo
Amabhamuza omoya amancane kanye nokungcola okucwebezelayo ngaphakathi kwemicu ye-fiberglass kunciphisa amandla aqinile emicu ngayinye. Ngaphansi kokugoba okuphindaphindiwe, lezi ziphambeko ziba amaphuzu okugxilisa ingqondo, okubangela ukuphuka kwefayibha kwangaphambi kwesikhathi futhi kunciphisa kakhulu ukuguquguquka nempilo eguquguqukayo.
Ukuhlanzeka kwempahla eluhlaza kubeka ukusebenza okuyisisekelo kwezindwangu ze-PTFE ezinezinga lokushisa eliphezulu:
I-High-purity PTFE inquma: izinga lokushisa eliphezulu lesevisi (260°C+), ukuzinza okungagxili kwesikhathi eside, ukwahlukanisa ugesi okuthembekile, nokuthobelana nothintana nokudla.
I-high-purity alkali-free fiberglass (i-E-glass, Na₂O <0.8%) kanye neziqinisekiso zokususa usayizi ophelele: amandla e-substrate emazingeni okushisa aphezulu, ukuqina kwe-dimensional, kanye nokunamathela kokunamathela okuzinzile ngaphandle kwe-delamination.
Ukungahlanzeki okwanele kunoma isiphi isixhumanisi kuzoholela ekuhlulekeni ngaphambi kwesikhathi - ukuphuzi, ukubola, ukuhlukaniswa kwe-insulation, nokulahlekelwa okungenayo induku - ikakhulukazi ngaphansi kwezimo ezinzima: izinga lokushisa eliphakeme lesikhathi eside, amandla aphezulu, noma izidingo eziqinile zenhlanzeko.
Imithombo ye -Aokai PTFE ithola kuphela i-emulsion ye-PTFE ephezulu (i-ion yensimbi ephansi, i-oligomer ephansi) nendwangu ye-E-glass fiberglass (i-alkali-free, ehlanzwe ukushisa ngokuphelele). Sihlinzeka ngezitifiketi zempahla futhi singasekela izinga lokudla kanye nezinhlelo zokusebenza zokushisa okuphezulu. Xhumana nathi ukuze uthole imininingwane enemininingwane.
Okuqukethwe okungenhla kunikezwa ngu I-Jiangsu Aokai New Materials Technology Co., Ltd.
