Kuumbwa uye Kugadzira Maitiro ePTFE Yakavharwa Fiberglass Fabric
Raw Materials uye Zvinhu Zvazvo
PTFE yakavharidzirwa fiberglass jira chinhu chakaumbwa chinosanganisa kusimba kwefiberglass pamwe neasina-tsvimbo epolytetrafluoroethylene (PTFE). Iyo base zvinhu, fiberglass, inoumbwa neakanaka girazi fiber akarukwa kuita jira. Izvi zvinopa yakanakisa tensile simba, dimensional kugadzikana, uye kuramba kutambanudza. PTFE, a synthetic fluoropolymer, inozivikanwa nekudzika kwayo kukweshana coefficient, inertness yemakemikari, uye yakanyanya-tembiricha kuramba.
Manufacturing Techniques
Kugadzirwa kwePTFE yakavharwa fiberglass jira inosanganisira akawanda-nhanho maitiro. Pakutanga, jira refiberglass rinonyatsocheneswa uye rakagadzirirwa kuve nechokwadi chekunamatira. Tevere, PTFE dispersion inoiswa kune jira uchishandisa nzira dzakasiyana dzekupfekedza senge dip coating, banga, kana spray coating. Iro jira rakaputirwa rinobva raita sintering process pakupisa kwepamusoro, kazhinji kutenderedza 700 ° F (371 ° C), iyo inosanganisa zvimedu zvePTFE uye inozvibatanidza kune fiberglass substrate. Iyi nzira inogona kudzokororwa kakawanda kuti iwane ukobvu hunodiwa uye zvivakwa.
Hunhu Kudzora Matanho
Yakaomesesa yemhando yekudzora matanho anoshandiswa mukati mekugadzira maitiro kuti ive nechokwadi chakafanana kuita kwechigadzirwa. Izvi zvinosanganisira kuongororwa nguva dzose kwezvinhu zvakabikwa, kutarisisa kukora uye kuenzana, uye kuyedzwa kwezvinhu zvemuviri senge simba rekusimba, kuramba kubvarura, uye kutsvedzerera kwepasi. Maitiro epamberi senge electron microscopy uye spectroscopy anogona kushandiswa kuongorora microstructure uye kemikari yejira rakavharwa. Pamusoro pezvo, zvigadzirwa zvakapedzwa zvinoedzwa zvakakwana kuti zvionekwe zvisizvo-tsvimbo, kuramba kupisa, uye kusimba pasi pemamiriro akasiyana.
Zvishandiso uye Zvakanakira zvePTFE Coated Fiberglass Fabric
Industrial Uses
PTFE yakavharwa jira refiberglass rinowana kushandiswa kwakakura muakawanda maindasitiri ekushandisa nekuda kwekusanganiswa kwayo kwezvivakwa. Muindasitiri yekugadzira chikafu, inoshanda sechinhu chakanakira mabhandi ekutakurisa, mashizha ekubikira, uye mapepa ekuburitsa, nekuda kweiyo isiri-tsvimbo uye kutevedzera FDA. Chikamu chezvemuchadenga chinoshandisa jira iri kuvharisa ndege uye kuvaka radome, richibatsirikana kubva pakureruka kwayo uye kuramba kutonhora kwakanyanya. Mumakemikari ekugadzira machira, machira akavharidzirwa ePTFE anoshandiswa kusefa masisitimu, majoini ekuwedzera, uye mabhii ekudzivirira, achiisa mari pakusagadzikana kwavo kwemakemikari uye kusimba.
Architectural Applications
Nyika yezvivakwa yakambundikira PTFE yakavharwa fiberglass jira rekuita zvakasiyana-siyana uye kukwezva kwayo. Isarudzo yakakurumbira yezvivakwa zvinorema, senge matenga enhandare, canopies, uye façade masisitimu. Kupenya kwejira kunobvumira kutapurirana kwemwenje wechisikigo uku uchipa dziviriro yeUV, zvichiita kuti ive yakanakira yekuvharisa atrium uye skylight masisitimu. Yayo yekuzvichenesa zvivakwa, nekuda kweiyo isiri-tsvimbo PTFE coating, inova nechokwadi chekuchengetedza yakaderera mutengo uye inogara kwenguva refu yekuona kukwezva. Zvakare, jira rinodzivirira moto zvivakwa zvinobatsira mukuvaka kuchengetedzwa, kusangana neyakaomesesa kodhi yemoto zvinodiwa.
Unique Advantages
PTFE yakavharwa fiberglass jira inozvirumbidza yakasarudzika seti yemabhenefiti ayo anoisa parutivi kubva kune zvimwe zvinhu. Kupisa kwayo kwakasiyana-siyana kunoibvumira kutsungirira kupisa kubva -100 ° F kusvika 500 ° F (-73 ° C kusvika 260 ° C) pasina kuora. Iro jira rakaderera friction coefficient rinoderedza kusakara uye kubvaruka muzvikamu zvinofamba, zvichiwedzera hupenyu hurefu hwemakina nemidziyo. Hunhu hwayo hwe hydrophobic hunoita kuti irege kudzivirira mvura, nepo oleophobic zvimiro zvayo zvinoramba mafuta negirizi. Izvo zvinhu zvakanakisa zvekuvharisa magetsi zvimiro zvinoita kuti zvikodzere kune akasiyana magetsi ekushandisa. Uyezve, kuramba kwayo kune UV mwaranzi uye zvinosvibisa zvemuchadenga zvinoita kuti igare kwenguva refu mukumisikidzwa kwekunze, zvichiita kuti ive mhinduro inodhura kumaindasitiri mazhinji.
Teflon Tape: Kuumbwa, Kushandisa, uye Kugumira
Kuumbwa uye Zvinhu
Teflon tepi, inozivikanwawo sePTFE tepi kana tepi yeplumber, chinhu chakatetepa, chinotambanuka chinoumbwa zvakanyanya ne polytetrafluoroethylene (PTFE). Kusiyana nePTFE yakavharidzirwa fiberglass jira , Teflon tepi haina inosimbisa substrate. Iyo tepi inogadzirwa kuburikidza nenzira inonzi paste extrusion, apo PTFE resin inosanganiswa nemafuta uye inomanikidzwa kuburikidza nefa kuti igadzire firimu yakaonda, ine porous. Iyi firimu inobva yatambanudzwa kuwedzera simba rayo uye kuderedza ukobvu hwayo. Iyo tepi inoguma yakapfava, inochinjika, uye ine yakaderera density, kazhinji kubva 0.35 kusvika 0.75 g/cm³. Teflon tepi inogara nhaka yakawanda yePTFE inobatsira zvinhu, zvinosanganisira makemikari kuramba, kukwesha kwakaderera, uye kugona kutsungirira kwakasiyana siyana kwekushisa.
Common Applications
Teflon tepi inowana kushandiswa kwayo kwekutanga mukushandisa pombi dzemvura setambo yekusimbisa tepi. Kana yakaputirwa pashinda dzepombi uye zvinosungirirwa, inozadza mavhodhi pakati peshinda, ichigadzira chisimbiso chisina mvura uye chinopinda mhepo. Izvi zvinoita kuti ive yakakosha mukudzivirira kudonha mumvura uye gasi mitsetse. Kupfuura pombi dzemvura, Teflon tepi yakawana utility mune mamwe akasiyana minda. Mumagetsi, inoshandiswa sechinhu chinodzivirira kune waya netambo. Maindasitiri eAerospace anoishandisa pakuzora zvikamu zvinofamba muinjini dzendege. Mumakemikari marabhoritari, tepi yeTeflon inoshandiswa kuvhara majoini egirazi mumaseta emidziyo. Izvo zvisiri-tsvimbo zvimiro zvinoita kuti zvive zvakakosha mukurongedza maapplication, kunyanya kumichina yekuisa chisimbiso inobata zvinhu zvinonamira.
Kunogumira uye Kufunga
Pasinei nekusiyana-siyana kwayo, tepi yeTeflon ine zvimwe zvipimo zvinotadzisa kushandiswa kwayo mumashandisirwo apo PTFE yakavharwa fiberglass jira rinopfuura. Iyo tepi yakaderera tensile simba inoita kuti isakodzere kune maapplication anoda yakakwira chimiro kuperera. Haikwanise kumirisana nedzvinyiriro dzakanyanya kana kushushikana kwemagetsi, kudzikisira kushandiswa kwayo mumaindasitiri. Teflon tepi yakatetepa uye ine porous hunhu zvinoreva kuti inopa kushoma kwekudziya kwekudzivirira kana ichienzaniswa nePTFE machira akavharidzirwa. Kunyange ichikwanisa kubata tembiricha yakakura, inoshaya kugadzikana kwedimensional yezvakasimbiswa PTFE zvinhu pakupisa kwakanyanya. Iyo tepi kutambanudza, kunyange ichibatsira pakugadzira zvisimbiso, inogona kunge iri dhizaini mumashandisirwo anoda chaiwo, asingachinji chiyero. Pamusoro pezvo, tepi yeTeflon haina kukodzera kushandiswa neakasimba oxidizing agents kana alkali simbi, sezvo izvi zvinogona kukanganisa PTFE zvinhu.
Mhedziso
Nepo PTFE yakavharwa jira refiberglass uye tepi yeTeflon ichigovera zvisiri-tsvimbo zvimiro zvePTFE, zvinoshanda zvakasiyana nekuda kweakasiyana maumbirwo uye zvimiro. PTFE yakavharwa jira regirazi refiberglass, rine mavakirwo aro akasimba uye zvinhu zvakasiyana-siyana, rinokunda muindasitiri nekuvaka zvikumbiro zvinoda simba, kusimba, uye kusapisa kupisa. Teflon tepi, kune rumwe rutivi, inopenya mukuisa chisimbiso nekuzora maapplication uko kutetepa kwayo uye kutambanudza kwayo kunobatsira. Kunzwisisa misiyano iyi kwakakosha pakusarudza zvinhu zvakafanira kune zvakanangana zvinodikanwa, kuve nechokwadi chekuita kwakakwana uye hupenyu hurefu mumashandisirwo akasiyana mumaindasitiri.
Taura nesu
Yemhando yepamusoro PTFE yakavharwa jira refiberglass uye nhungamiro yehunyanzvi pamashandisirwo ayo, vimba Aokai PTFE . Zvigadzirwa zvedu zvekutanga zvinopa kusimba kusingaenzaniswi, kupisa kupisa, uye kusanamatira zvivakwa, kuve nechokwadi chekuita kwepamusoro munzvimbo dzakasiyana dzeindasitiri. Sangana nemusiyano weAokai PTFE - taura nesu nhasi pa mandy@akptfe.com kuongorora kuti zvinhu zvedu zvepamberi zvinogona kukwidziridza mapurojekiti ako uye maitiro.
