PTFE Powder Plasma Hydrophilic Kurapa
PTFE Powder Plasma Hydrophilic Kurapa
PTFE powder inoshandiswa zvakanyanya seyekuwedzera muakasiyana-siyana-based coatings uye poda coatings, senge mapurasitiki ejasi, pendi yehuni, coil coil, UV kurapa machira, uye pendi, kuvandudza mashandiro avo ekuburitsa mold, pamusoro pekutanga kuramba, lubricity, chemical resistance, kupikisa mamiriro ekunze, uye kudzivirira mvura. PTFE ma micro-powder anogona kushandiswa semafuta akasimba panzvimbo pemafuta ekuzora. Iwo anogona zvakare kushandiswa kunatsiridza kuyerera kweinki uye seanopokana-kupfeka mumiririri, ane yakajairika kuwedzera huwandu hwe1-3wt%. Iwo anogona zvakare kushandiswa mune asina-tsvimbo coatings yekubika, ine yakajairika yekuwedzera huwandu isingapfuuri 5wt%. Organic solvent dispersion inogonawo kushandiswa seyekuburitsa mumiririri. Iwo anogona zvakare kushandiswa seanoshanda zvakanyanya anti-drip agents mumapurasitiki akasiyana, akadai seABS, polycarbonate (PC), polyurethane (PU), uye polystyrene (PS).
PTFE icrystalline polymer yakagadzirwa kubva kune tetrafluoroethylene monomers, ine yakanakisa magetsi ekudzivirira, yakadzika pasi tension uye friction coefficient, isingabatike moto, kuramba kuchembera kwemuchadenga, kuchinjika kwepamusoro uye kuderera, uye yakakwirira michina.
Nekudaro, nekuda kweiyo yakanyanya symmetric uye isiri-polar chimiro, kushomeka kwemapoka anoshanda, uye yakakwirira crystallinity, PTFE chinhu chakanyanya chisiri-polar chine simba hydrophobicity, makemikari inertness, yakaderera pamusoro pesimba, uye yakashata yekunyorova uye kunamatira kune zvimwe zvinhu, izvo zvinomisa zvakanyanya kushandiswa kwayo. Naizvozvo, kuwedzera kushandiswa kwe PTFE, nzvimbo yayo inofanirwa kurapwa kuti iwedzere simba repamusoro uye kuvandudza hydrophilicity yayo.
Plasma kurapwa ndeimwe yeanokurumidza kusimukira matekinoroji e PTFE kugadziriswa kwepamusoro mumakore achangopfuura. Nheyo yekugadziriswa kweplasma ndeye kushandisa ion bombardment kana jekiseni kumusoro kwepolymer kugadzira zvisungo zvakatyoka kana kuunza mapoka anoshanda, nekudaro kumisa pamusoro kuti kuwedzere kunamatira kwechinhu. Magasi akajairika anoshandiswa anosanganisira oxygen, hydrogen, nitrogen, carbon tetrafluoride, uye argon. Iyo bombardment yeinert gas plasma inogona kushandura chimiro chepamusoro checopolymer.
Plasma ine zvimedu zvinoshanda senge maerekitironi, ions, uye mahara radicals. Kugadziriswa kwepamusoro kweplasma kunosanganisira kushandurwa kwemuviri uye kemikari. Shanduko yemuviri ndiko kubhomba kwemaerekitironi nemaion pamusoro pepolymer, izvo zvinotyora zvisungo zvemakemikari zvepolymer cheni, zvinokonzeresa maitiro, uye zvinogadzira zvigadzirwa zvinosvibisa zvinoisa pamusoro pepolymer. Kugadziriswa kwemakemikari kunosanganisira kuunza mapoka anoshanda kuburikidza nemahara radicals anobata nepolymer pamusoro, achichinja kemikari yepasi. Zvese zviri zviviri kugadziridzwa kwemuviri uye kemikari zvinokonzeresa shanduko pazvinhu zvepasi. Munguva yekurapa kweplasma, kuiswa kwemapoka ekushanda uye maitiro ekuora mwoyo haagoni kuparadzaniswa asi anoitika panguva imwe chete, uye maitiro ekuderedza haadzivisiki. Kiyi yekuchinja kwepamusoro kunoshanda kudzikisa maitiro ekudzikisira uye kuwedzera basa rekuita basa rekutanga boka.
The PTFE poda shanduko inoshandisa poda plasma yekuchenesa muchina. Plasma inoshanda paupfu kuti ichinje nemaune chimiro chayo chemuviri uye chemakemikari, ichichengetedza iyo yepakutanga zvimiro zvehupfu, kuti ipe hutsva hutsva hwepamusoro, ichichinja nzvimbo dzayo dzepamusoro kubva kune hydrophobic kuenda kune hydrophilic kana zvinopesana, nekudaro ichivandudza kunyorova kwehupfu hupfu uye. kuwedzera kunamatira kwehupfu zvidimbu mukati.
