PTFE high-temperature jira (PTFE-coated fiberglass) inogona kugadzirwa uchishandisa nzira mbiri dzakasiyana: single-dip impregnation uye multi-dip impregnation . Sarudzo pakati pavo inotaridza ukobvu hwekufukidzira, kunaka kwepamusoro, danho rekuita, uye mutengo.
Mune imwe-dip process, jira refiberglass rinopfuura nepakati chete yakazara impregnation-kuomesa-sintering cycle. Mukuita kwakawanda-kudhibha, inodzokororwa matenderedzwa - kazhinji 2-3 inomhanya inopfuura gumi nemaviri - ichivaka PTFE layer ne layer.
Aokai PTFE inoshandisa ese ari maviri maitiro zvichienderana nekushandisa. Iri gwara rinotsanangura tsananguro, kuyerera kwemaitiro, maitiro, uye akajairika mashandisirwo ega ega, pamwe nedivi-ne-parutivi kuenzanisa kwekuita.
Single-Dip Impregnation process - Inokurumidza uye Inodhura-Inoshanda
1. Tsanangudzo uye nzira inoyerera
Tsanangudzo: Fiberglass jira rinopfuura nekutenderera kumwe chete kwakazara kwe impregnation-drying-sintering kuti ibudise yakapedzwa PTFE-yakavharwa jira.
Kuyerera kwekugadzira:
2. Maitiro maitiro
Resin pickup ishoma, inoburitsa yakatetepa-geji, yakaderera-girama jira
Iyo yakarukwa magadzirirwo efiberglass haakwanise kuzadzwa zvizere, zvichikonzera nzvimbo yakakasharara ine micro-pinholes
Kuvharirwa kwePTFE kusina kukwana kunotungamira kusimba rakadzikira, simba redielectric, makemikari-kupinza kuramba, uye kusaita tsvimbo.
Iyo yekugadzira kutenderera ipfupi nekunyanya kushanda zvakanaka uye yakaderera mutengo wekugadzira zvakanakira
3. Mashandisirwo akajairika
Jira redhipi rimwechete rinogamuchirwa kune zvimiro zvine zvakaderera zvinodiwa pakukora, kusapinda, uye kutsvedzerera kwepasi:
Yakaderera-giredhi insulating gaskets
Meti dzenguva pfupi dzisina tsvimbo
Semi-permeable zvinhu zvinochengeta chikamu chemhepo permeability
Asina-akakosha maindasitiri anoshandisa uko mutengo uri wekutanga mutyairi
1. Tsanangudzo uye nzira inoyerera
Tsanangudzo: Iyo fiberglass substrate inodzokororwa kutenderera kwe impregnation-kuomesa-sintering, kazhinji kubva pa2-3 inomhanya kusvika kunopfuura gumi nemaviri kutenderera. Imwe neimwe inotevera dhizaini inoiswa pane iripo PTFE coating yekuvaka ukobvu, kuzadza ma voids, uye kugadzirisa pamusoro pekukanganisa.
Kuyerera kwekugadzira:
Strategy kusiyana:
Kutenderera kwekutanga: Yakaderera-viscosity, yakakwirira-inopinza PTFE kupararira - inopinda zvizere mukati mefiber bundles.
Matanho ekupedzisira: Yepamusoro-viscosity kana yakakwirira-yakasimba-zvirimo dispersions - inovaka pamusoro pemafirimu uye inovhara mapinhole.
2. Maitiro maitiro
Ukobvu uye PTFE kurodha kunogona kunyatsogadziriswa
PTFE chikamu chinogona kusvika 50-70% kana kutopfuura
Kudzokororwa kupindira uye sintering inozadza mapundu pakati pe fiber filaments uye kubvisa pinholes, kuendesa yakatsetseka, compact coating.
Yakanakisa isina-tsvimbo uye kuburitsa zvivakwa
Yakanakisa makemikari-corrosion kuramba uye kusamira
Zvakanyanya kunatsiridza dielectric simba uye vhoriyamu resistivity
Yakagadzika chimiro kutendeseka ine tembiricha yenguva refu yebasa inosvika 260°C
Trade-offs: Yakawedzerwa kugadzirwa inotungamira-nguva, yakakwirira-simba mashandisiro, yakasimba maitiro ekudzora, uye yakakwirira yakazara mutengo wekugadzira.
4. Mashandisirwo akajairika
Multi-dip jira rinoshandisa premium-giredhi, yepamusoro-yekupedzisira maindasitiri zvikamu uko kuita kunoruramisa mutengo:

Single-dip impregnation inokurumidza kutetepa-firimu yekunamira nzira ine mapfupi ekugadzira magadzirirwo uye yakaderera mutengo, asi ichiganhurirwa nekushata kwepasi uye kuderera kwekudzivirira kuita.
Multi-dip impregnation ndeye layer-by-layer infiltration uye kuvaka-up nzira inoputira zvizere iyo fiberglass substrate. Inogadzira jira rakatsetseka, rakasvibira PTFE-yakavharwa ne premium-giredhi performance pamutengo wekuoma kwebasa uye mitengo yakakwira.
Aokai PTFE inogadzira ese ari maviri-dip uye akawanda-dip PTFE machira. Pakuda maindasitiri ekunyorera, angangoita ese epamusoro-kuita PTFE-akamisikidzwa fiberglass machira anogadzirwa kuburikidza neakawanda-dip process. Bata isu kuti tikurukure kuti nderipi giredhi rinoenderana nezvido zvako zvekunyorera.
Izvo zvakataurwa pamusoro pehunyanzvi zvemukati zvinopihwa ne Jiangsu Aokai New Materials Technology Co., Ltd.
Kana iwe uchida kuwana yakadzama tekinoroji paramita, makesi ekushandisa uye yakagadziridzwa mhinduro kune yedu yakazara-range chigadzirwa mutsara, kusanganisira PTFE yakakwirira-temperature jira, PTFE yakakwirira-temperature adhesive tepi, PTFE high-temperature mesh bhandi, seamless kupisa-press bhandi, single-sided PTFE jira, yakakwirira-tembiricha-inodzivirira girosi, inodzivirira-inodzivirira bhandi mu-fiber-inodzivirira jira. kuburikidza neruzivo rwekusangana pazasi:
Isu tinonamatira kune yakakosha huzivi hwehunyanzvi uye kutendeseka, yakatsaurirwa kupa imwechete-kumira maindasitiri mhinduro uye nehanya nevatengi sevhisi!
