Ungazisusa Kanjani Izithako Ezisele kanye Nezinto Eziphansi Ze-Molecular Embotsheni Ngesikhathi Sokukhiqizwa Kwendwangu Ye-PTFE High-Temperature

I-Jiangsu Aokai Izinto Ezintsha - Umkhiqizi Wezingubo Zokushisa Ezisezingeni Eliphezulu we-PTFE, ukukhombisa ukuthi kanjani. Ngesikhathi sokukhiqizwa kwendwangu yekhwalithi ephezulu ye-PTFE, izithasiselo ezisele kanye nezinto eziphansi zamangqamuzana ekugqokeni ziyizici ezibalulekile ezithinta ukumelana nokushisa kokugcina, ukukhululwa kwempahla nokuphepha kokudla komkhiqizo. Ukuqinisekisa ukusebenza kwendwangu ye-PTFE ephezulu yokushisa ihlangabezana nezindinganiso, inqubo eqinile yezigaba eziningi ibalulekile ukuze kukhishwe lokhu kungcola.

Isigaba Esiyinhloko: Ukuhlanzwa Kokwelashwa Okushisayo Okubalulekile kwe-PTFE I-High-Temperature Cloth Coating

Lena inqubo ebucayi kakhulu ekukhiqizweni kwendwangu yezinga lokushisa eliphezulu ye-PTFE, efinyelela ukuhlukaniswa okungokomzimba kokungcola okugqunyiwe ngokulawula izinga lokushisa okunembile.

Ngemuva kwe-PTFE emulsion impregnation ye-PTFE high-temperature cloth substrate, umkhiqizo uqala ukungena kuhhavini wokomisa izinga lokushisa eliphansi. Ngefilimu emanzi ebusweni, izinga lokushisa livame ukulawulwa ku- 240-285 ° C. Lesi sinyathelo asihlosile ukwakha ifilimu yokumboza, kodwa ukwenza umswakama, izinyibilikisi kanye nama-surfactants ezikhaleni zokumboza ngomoya oshisayo. Ukweqa lesi sigaba futhi uqhube ngokuqondile ukucwilisa izinga lokushisa eliphezulu kuzodala izimbobo noma amabhamuza phezulu, kulimaze kakhulu ukubumbana kwendwangu ye-PTFE enezinga eliphezulu lokushisa.

Ngokulandelayo, indwangu ye-PTFE enezinga eliphezulu lokushisa ingena endaweni enezinga eliphezulu lokushisa elingu- 360–380°C . Kuleli zinga lokushisa, izinhlayiya ze-PTFE ezingaphezulu ziqala ukuncibilika futhi zigeleze, zenze ifilimu evikelayo eqhubekayo. Khonamanjalo, leli zinga lokushisa elingaphezulu kwendawo yokuncibilika ye-PTFE linikeza amandla e-kinetic anele kuma-oligomer asele kanye nama-monomers angaphenduliwe ngaphakathi kwesembozo ukuze ahwamuke futhi abaleke ku-substrate. Ukulawulwa okunembile kwezinga lokushisa le-sintering kubalulekile ekuhlanzekeni kwendwangu yezinga lokushisa eliphezulu le-PTFE:

· Amazinga okushisa angaphansi kuka-360°C aholela ekuguquguqukeni okungaphelele kokungcola kwangaphakathi;

· Amazinga okushisa angaphezu kuka-390°C abangela ukuwohloka nokubola kwamaketanga e-molecular PTFE, angcolise i-coating esikhundleni salokho.

Isigaba Sesibili: Ukulawulwa Kwenqubo Enhle ku-PTFE Ukukhiqizwa Kwendwangu Yezinga Lokushisa Okuphezulu

Ngaphezu kokwelashwa okushisayo okuyisisekelo, ukulawula okuningiliziwe ngesikhathi sokukhiqiza kuphinde kusize ukuthuthukisa izinga lokuhlanzeka kwendwangu ye-PTFE ephezulu lokushisa.

· Ukwelashwa kwe-Substrate Pretreatment : Ngaphambi kokumbozwa, indwangu ye-fiberglass esetshenziselwa indwangu yezinga lokushisa eliphezulu ye-PTFE ikhishwa kahle nge-waxing kanye nokwelashwa kwe-degumming. Izinsalela zezinto eziphilayo ezakhiweni eziyisisekelo zizoba carbonize ngesikhathi sokushisisa okulandelayo futhi zihlale ku-interlayer, zenze amaphutha aqhubekayo angenakuqedwa.

· Ukuhlanza Okusizayo : Ngendwangu ye-PTFE ephezulu yokushisa edinga ukuhlanzeka okuphezulu, ukuhlanzwa kwe-inthanethi ngezincibilikisi ezithile noma ukwelashwa kwe-ultrasonic kungasetshenziswa emikhiqizweni eqediwe kancane, kuthuthukise ukususwa kothuli olungaphezulu nokucubungula amabala kawoyela.

Isiteji Semfundo Ephakeme: Isu Lokulawula Umthombo Lokukhiqizwa Kwendwangu Ye-PTFE Esezingeni Eliphezulu

Indlela efanelekile yokuhlanza iwukuvimba ukungcola ngaphambi kokuthi kungene ohlelweni lomkhiqizo, okudinga abahlinzeki bendwangu bezinga lokushisa eliphezulu be-PTFE ukuthi basungule izindinganiso eziqinile zokulawula umthombo.

· Ukukhethwa Kwezinto Ezingavuthiwe Zekhwalithi Ephezulu : Izinsalela zokuhlakaza ze-PTFE ezinobumsulwa obungekho ngaphansi kuka-99.9% kuphela okufanele zisetshenziswe njengezinto zokusetshenziswa zokumboza. Ama-resin asezingeni eliphansi aqukethe izinto ezinama-molecular aphansi ngokweqile, okwenza kube nzima ukukhiqiza indwangu esezingeni eliphezulu ye-PTFE kungakhathaliseki ukuthi i-sintering ithuthukiswa kanjani kamuva.

· Ukulawulwa Kwe-ejenti Esizayo : Lapho izithambisi noma ama-ejenti okulinganisa kudingekile ekwakhiweni kokunameka, izinhlobo ezibilisa kancane, neziguquguqukayo kakhulu zizokhethwa, futhi umthamo wazo ulawulwe ngokuqinile ukuze kuqinisekiswe ukuqedwa ngokuphelele komkhiqizo osuphelile.

Indawo Yokukhiqiza Ehlanzekile : Ishabhu yokukhiqiza izogcina ingcindezi nokuhlanzeka okuhle. Izinto zangaphakathi zangaphakathi zifakwe i-PTFE noma zenziwe ngensimbi engagqwali ukuze kuvinjelwe uthuli nemfucumfucu evela endaweni noma ukuhuzuka kwemishini ekuweleni efilimini emanzi bese kwakheka amabala okungcola anombala ekunambeni.

Umnyombo wokukhipha izinto ezisele ku-PTFE ezinezinga eliphezulu lokushisa okunendwangu usekulawulweni okunembile kwezinga lokushisa le-sintering kanye nejika lokushisisa. Kuphela ngokuhlanganisa ukwelashwa okushisayo nokulawula ukuhlanzeka okuphelele kwenqubo lapho indwangu eqediwe ye-PTFE enezinga eliphezulu lokushisa ingaletha izakhiwo ezinhle kakhulu ezingabambeki, ezimelana nokushisa nezingashisi kakhulu.

Ulwazi olungenhla lunikezwe i- Jiangsu Aokai New Materials Technology Co., Ltd.

Ukuze uthole imingcele enemininingwane, izimo zohlelo lokusebenza nezixazululo ezenziwe ngokwezifiso zohlu lwethu oluphelele lomkhiqizo ohlanganisa i-PTFE indwangu yokushisa ephezulu, i-PTFE itheyiphu yokushisa ephezulu, ibhande le-PTFE elinezinga eliphezulu lokushisa, ibhande elingenamthungo lemishini yokubopha, indwangu ye-PTFE enohlangothi olulodwa, izinga lokushisa eliphezulu elinokushisa okuphezulu, kuyajabulisa ukuthintana nathi ngendwangu ye-fiber
