Jiangsu Aokai New Materials, inyanzvi inogadzira PTFE yakakwirira-tembiricha tepi, inogovera hutungamiriri hwehunyanzvi. Kana ichishandiswa muvacuum coating, vacuum kupisa kurapwa uye dzimwe nzvimbo dzevacuum, PTFE yakakwirira-tembiricha tepi ine zvakasiyana-siyana zvepakati pekuita zvinodiwa zvichienzaniswa nemhepo yekushandisa. Low outgassing, low volatile emission uye hutsanana hwepamusoro ndizvo zvinonyanya kukosha. Zviratidzo zvakakosha zvinofanirwa kuongororwa zvakanyorwa sezvizvi:
1. Vacuum Outgassing Property (Yakanyanya Yakakosha Indicator)
Iyi ndiyo yakasarudzika performance index yevacuum application. Pasi pekumanikidzwa kwakadzika uye kupisa kwakanyanya, tepi inosunungura gasi rinoputika, iro rinoderedza vacuum degree. Condensed volatiles inosvibisa maoptical components, sputtering targets and workpieces, zvichikonzera kuvharwa nemhute, kusaona zvakanaka kwemafirimu uye kunyange kurambwa zvachose kwechigadzirwa.
· Total Mass Loss (TML): Zvose zvinodiwa TML ≤ 1.0%; zvikumbiro zvemhando yepamusoro zvakaita seaerospace uye maindasitiri emaziso anoda TML ≤ 0.5%.
· Yakaunganidzwa Volatile Condensable Materials (CVCM): Yakanyatsodzorwa, kazhinji CVCM ≤ 0.1%; ultra-rigid scenarios inoda CVCM ≤ 0.01%.
2. Temperature Resistance Grade
· Kuenderera mberi tembiricha yebasa: Iyo PTFE-yakavharwa fiberglass substrate yePTFE tepi inogona kushingirira kuratidzwa kwenguva refu pa260°C. Nekudaro, kupikisa kwekushisa kweiyo adhesive layer kunofanirwa kusimbiswa panguva imwe chete. Conventional silicone PSA inopa kuenderera kwekupisa kupisa kwakatenderedza 200 ° C, nepo high-performance silicone adhesive inogona kusvika 260 ° C.
· Yenguva pfupi yepamusoro-soro tembiricha: Tarisa uone kana tembiricha yepakarepo panguva yekugadziriswa ichipfuura tepi yenguva pfupi yekupisa muganhu (kazhinji ≤300 ° C). Tembiricha yakawandisa inozoita carbonize uye kuora iyo inonamira layer, zvichikonzera kusvibiswa kwakanyanya mukati mevacuum chamber. Cherechedza: Kana vacuum kupisa kupisa tembiricha kupfuura 260 ° C, PTFE tepi haichashandi; polyimide (Kapton) tepi kana aluminium foil tepi ichagamuchirwa panzvimbo.
3. Adhesive Type & High-Temperature Holding Power
· Adhesive system sarudzo: Silicone pressure-sensitive adhesive ndiyo huru sarudzo yevacuum application nekuda kwekunyanya kupisa kwayo. Zvakangodaro, akajairwa silicone adhesives ane akawanda akaderera-molecular siloxanes, ayo anoputika pasi pepamusoro-tembiricha vacuum uye anosvibisa workpiece, kunyanya nzvimbo dzemaziso uye nzvimbo dzemagetsi. Naizvozvo, yakanyatsocheneswa yakaderera-outgassing silicone adhesive kana isiri-silicone adhesive maumbirwo anodiwa.
· Yakakwira-tembiricha yekubata simba: Pasi peyakasanganiswa vacuum uye yakakwirira-tembiricha mamiriro, zvinokambaira, kusimudza mupendero kana kuzara kupepeta kwe tepi kuchavhara zvakananga mapipe ekutsvaira uye kuunza zvitsva zvinosvibisa. Iyo shear inobata nguva pakushanda tembiricha inofanira kusimbiswa.
4. Hutsanana & Ionic Kusvibiswa
· Kupindirana kwemukamuri: Tepi ichave isina fibre yekudururwa uye lint pamakona ekucheka. Matepi anogadzirwa munzvimbo dzakachena anodiwa.
· Yakaderera ionic yemukati: Yevacuum maitiro mune semiconductor uye MEMS maindasitiri, halogen ions (Cl) uye simbi ions (Na, K) iri mutepi inonaya pakupisa kwakanyanya, corroding circuits kana kushandura doping concentration. Kumbira ionic extractables bvunzo mishumo kubva kune vatengesi.
· Zero silicone kutama kwemafuta: Kunze kwekunyungudika kunoputika, yemahara silicone oiri mukati mekunamira inogona kukwira nepamusoro pepamusoro uye kukonzera kukundikana mune inotevera bonding uye welding maitiro. Taura zero silicone oiri yekufambisa giredhi yeakakosha maapplication.
PTFE inogara iri yepamusoro-insulation zvinhu. Static charge inoungana zviri nyore pamusoro payo kuburikidza nekukweshana kana kusvuura mukati mevacuum chamber. Electrostatic discharge inogona kukanganisa zvinhu zvemagetsi zvemagetsi kana kukwezva zvinosvibisa.
· Chinodiwa chechiratidzo: Pakudzivirira nekudzivirira nzvimbo dzinonzwa magetsi, anti-static PTFE tepi inodiwa nepamusoro peresisivity kubva ku10⁶ ~ 10⁹ Ω/sq, uye yakagadzikana anti-static performance inofanirwa kuchengetedzwa mushure mekuratidzwa kwepamusoro-tembiricha.
6. Plasma & Chemical Resistance
· Plasma kuramba: Mukuita sputtering uye PECVD, tepi yakafumurwa kumhepo yeplasma ichaiswa, ichiburitsa fluorine yemahara radicals inosvibisa mafirimu akaiswa uye inobvisa vacuum makamuri. Ongorora kushanda kwacho pachine nguva, kana chinja kune yakawanda plasma-resistant polyimide tepi kana zvichidikanwa.
· Mushonga wemakemikari: Kusara kwemafuta mhute uye kuchenesa zvinonyungudutsa zvinogona kuvapo panguva yevacuum kupisa kupisa; zvese zvinonamira uye substrate zvinoramba kuzvimba uye kuita kwemakemikari.
7. Dimensional Kugadzikana & Thermal Shrinkage Rate
Kuwedzera kupisa kwemafuta pakupisa kwepamusoro kunofumura mipendero yakafukidzwa kana kugadzira makwinya anonamira, kukanganisa masking chaiyo uye kuenderana.
· Chinodiwa chechiratidzo: Ongorora dhizaini shrinkage data yakapihwa nevagadziri (yakaedzwa mushure memaminitsi makumi matatu pa260 ° C). Yekutanga vacuum-giredhi tepi inowana shrinkage pazasi 2% kana kutodzika.
Pfupiso yeSarudzo Rerumbidzo
Paunenge uchitenga PTFE yakakwirira-tembiricha tepi yevacuum nharaunda, kupisa kwega hakuna kukwana. Kumbira ASTM E595 outgassing bvunzo mishumo kubva kune vatengesi, zvakajeka taura vacuum sevhisi mamiriro uye inoda akasarudzika akadzika-outgassing matepi ane yakacheneswa silicone adhesive. Nezvemaitiro akakosha ekugadzira, ita diki-chikero coupon bvunzo kuyera chidimbu kudzvinyirirwa kuchinjika pane vacuum geji uye ongorora inogona kusvibiswa kune zvakapedzwa zvigadzirwa.
Izvo zviri pamusoro pehunyanzvi zvemukati zvinopihwa ne Jiangsu Aokai New Materials Technology Co., Ltd.
Kana iwe uchida kuwana tsanangudzo dzakadzama, mamiriro ekushandisa uye zvigadziriso zvakagadziridzwa zvechigadzirwa chedu chizere chepodfolio chinosanganisira PTFE yakakwirira-tembiricha jira, PTFE yakakwirira-temperature adhesive tepi, PTFE yakakwirira-temperature mesh bhandi, seamless kupisa kupisa bhandi, single-sided PTFE jira, yakakwirira-tembiricha inodzivirira pazasi inodzivirira girazi, tapota taura nesu pazasi-inodzivirira girazi.
