Iyo Yakasvibirira Material Kuchena Inobata sei PTFE Yakakwira-Tembiricha Yemucheka Performance

PTFE high-temperature jira (PTFE-yakavharidzirwa fiberglass) yakanaka chete seyakagadzirwa inoshandiswa kuigadzira. Zvikamu zviviri zvine basa: iyo PTFE resin / emulsion (iyo yekupfeka) uye iyo fiberglass substrate (iyo yekusimbisa). Kusachena mune chero - simbi ions, yakaderera-molecular-huremu mapolymer, asara saizing ejenti, kana alkali oxides - inogona kukonzera kutadza nguva isati yakwana: kutsvuka, kutsemuka, kurasikirwa kweasina tsvimbo, delamination, kana kuputsika kwekudzivirira.

Aokai PTFE inoshandisa yakakwirira-kuchena mbishi zvinhu uye yakasimba maitiro ekutonga. Gwaro iri rinotsanangura kuti kuchena kunobata sei chikamu chega chega chekuita uye nei zvichikosha pakuda maapplication.

PTFE Raw Material Kuchena - Ndezvipi Zvisina Kuchena Zviripo?

Kusachena kwakajairika muPTFE kunosanganisira:

• Unreacted monomers uye yakaderera-molecular-uremu mapolymers

• Vasara vanotanga uye vanoparadzira (semuenzaniso, PFOA)

• Metal ions (simbi, mhangura, sodium)

• Zvishandiso zvekugadzirisa uye ne-zvigadzirwa

Kuchena kwepamusoro kunogonesa izvo zvinhu kuti zviunze kuita padhuze nekwakanaka zvakatemwa.

1. Kupisa kupisa uye kugadzikana kwekushisa

Metal ions (iron, mhangura, sodium) inoshanda seyakasimba inokonzeresa PTFE kupisa kwemafuta . Pasi pesevhisi yenguva refu iri pamusoro pe260°C, kunyangwe kuronda tsvina yesimbi kunomhanyisa kutsemuka kwemamolecular cheni, zvichikonzera kukurumidza kuputirwa nekutsemuka. High-purity PTFE inoratidzira tembiricha yepamusoro yekuora yekupisa, inoramba yakachena yakachena, uye inoramba yero zvinobudirira.

2. Kusina-tsvimbo kushanda uye pamusoro pemhando

Low-molecular-weight polymers neoiri by-products zvinotamira kunzvimbo yekuputira panguva yekupisa-kupisa, kuumba mvura.

• Yakashata isiri-tsvimbo pfuma: Iyo yepamusoro inova tacky uye inonamira kune yakagadziriswa zvinhu (chikafu, anonamira matepi).

• Njodzi yekusvibiswa: Muchikafu-giredhi uye zvekurapa zvikumbiro, mvura inotama inogona kusvibisa zvigadzirwa uye kutadza hutsanana. Kuchena chiratidzo chepakati chechikafu-kubata PTFE machira.

3. Magetsi ekudzivirira kushanda

Ioni dzisina kuchena (metal cations, halogen ions) inoshanda sevatakuri vanotakura, zvakanyanya kuderedza vhoriyamu resistivity uye kuparara kwemagetsi. Kune yakakwira-insulation application (semuenzaniso, magetsi ekudzivirira gaskets), mbishi zvinhu kuchena kwakakosha. Mapores anokonzerwa netsvina anogonawo kutungamira pakubuda muchidimbu.

4. Kemikari kuramba uye compactness

Soluble tsvina inobuda kunze kana yakafumurwa kumakemikari midhiya, ichisiya micro-pores mukati mejasi. Uku kukanganisa kunobvumira gasi rinoora uye mvura kuti ipinde uye kukanganisa iyo fiberglass substrate, ichikanganisa mashandiro emucheka.

Fiberglass Substrate Kuchena - Alkali Zvemukati Nyaya

Fiberglass haisi yakachena silicon dioxide. Chimiro chayo chemakemikari chinotsanangura kupisa kupisa, simba remagetsi, uye kubatana nePTFE.

1. Alkali metal oxide content - the decisive factor

Pakupisa kwepamusoro, alkali simbi ions kubva pasi-kuchena girazi haingori simba jira pacharo asiwo inokonzera kuparara kwePTFE coating , ichikurumidza kutadza zvachose. Pamusoro pezvo, girazi repakati / rakakwirira-alkali rinotora hunyoro, zvichiita kuti kudzivirira kwekudzivirira kudonhe zvakanyanya.

2. Sizing agents - imwe tsvina

Sizing agents (starch, PVA, mafuta) anoiswa panguva ye fiberglass weaving kuchengetedza fiber. Kana isina kubviswa zvachose pamberi pe PTFE coating, zvakasara organics carbonize, decompose, uye gasify panguva sintering kunoda kusvika 400°C.

• Kuremara kwepamusoro: Yellow discoloration, mavara matema, mablister - zvigadzirwa zvinotadza kutarisisa chitarisiko.

• Husina kusimba hwekubatana kwechiso: Zvisaririra zveCarbhoni zvinovharira makemikari uye kumira kwemuviri pakati pePTFE nefiberglass, zvichikonzera delamination, mablistering, uye kusvuuka panguva yebasa.

3. Flexural kuneta kuramba

Micro air bubbles uye crystalline tsvina mukati mefiberglass filaments inoderedza kusimba kwesimba remunhu. Pasi pekupeta kwakadzokororwa, kuremara uku kunova nzvimbo dzekushushikana, zvichikonzera kutanga kwefiber kutyoka uye kudzikisa zvakanyanya kushanduka uye kushanduka hupenyu.

Pfupiso – Kuchena kunoseta Performance Ceiling

Raw material kuchena inoisa iyo yakakosha kuita kwePTFE yakakwirira-tembiricha machira:

• High-purity PTFE inosarudza: tembiricha yepamusoro yebasa (260 ° C+), kugadzikana kwekugara kwenguva refu, kugadzika kwemagetsi kwakavimbika, uye kuenderana kwekudya.

• Yakakwirira-kuchena alkali-isina fiberglass (E-girazi, Na₂O <0.8%) pamwe neyakakwana saizi yekubvisa garandi: substrate simba pakupisa kwepamusoro, kugadzikana kwedimensional, uye yakagadzikana coating adhesion pasina delamination.

Kusakwana kuchena mune chero chinongedzo kuchaita kuti kukundikana kusati kwasvika - yero, delamination, insulation kuparara, uye kurasikirwa kweasina tsvimbo - kunyanya pasi pemamiriro ezvinhu akaomarara: tembiricha yenguva refu, high voltage, kana hutsanana hwakasimba zvinodiwa.

Aokai PTFE masosi chete yakakwirira-kuchena PTFE emulsion (yakaderera simbi ion, yakaderera oligomer) uye E-girazi fiberglass jira (alkali-isina, yakazara kupisa-yakacheneswa). Isu tinopa zvitupa zvezvinhu uye tinogona kutsigira chikafu-giredhi uye yakakwira-insulation application. Bata isu kuti uwane ruzivo rwakadzama.

Zviri pamusoro apa zvinopihwa ne Jiangsu Aokai New Materials Technology Co., Ltd.

Kana iwe uchida kudzidza zvakawanda pamusoro pezvakatsanangurwa zvakatsanangurwa, mamiriro ekushandisa uye zvigadziriso zvakagadziridzwa zvechigadzirwa chedu chizere, kusanganisira PTFE machira ekupisa, PTFE yakakwirira-tembiricha matepi, PTFE mesh mabhandi, seamless bonding muchina mabhandi, single-sided PTFE jira, yakakwirira-tembiricha inodzivirira inodzivirira machira egirazi, uye machira anodzivirira girazi
