Vharuvhu yeshavishavi inodzivirira ngura ine fluoroplasticKuisa polytetrafluoroethylene resin (kana kuti profile processed) pamadziro emukati mesimbi kana simbi yevharuvhu yebhatafurayi kana pamusoro pekunze kwezvikamu zvemukati zvevharuvhu yebhatafurayi nenzira yekuumba (kana inlay). Hunhu hwakasiyana hwevharuvhu yebhatafurayi hunopesana nemidziyo yakasimba inoparadza inogadzirwa kuita mhando dzakasiyana dzevharuvhu yebhatafurayi nemidziyo yekumanikidza.
Muzvinhu zvinodzivirira ngura, PTFE ine mashandiro akanaka kwazvo. Kuwedzera kune simbi yakanyungudutswa, elemental fluorine uye aromatic hydrocarbons, inogona kushandiswa muhuwandu hwakasiyana hwehydrochloric acid, sulfuric acid, nitric acid, aqua regia, organic acid, strong oxidant, concentrated , alternating dilute acid, alternating alkali uye akasiyana-siyana organic agents irandom reactions. Lining PTFE pamadziro emukati me butterfly valve haingokundi chete zvikanganiso zvePTFE strength yakaderera, asiwo inogadzirisa dambudziko rekusagadzikana kwe corrosion kwezvinhu zve butterfly valve theme. Kushanda kusina kunaka uye mutengo wakakwira. Pamusoro pezvo, kuwedzera pakugadzikana kwayo kwakanaka kwemakemikari, PTFE ine hunhu hwakanaka hwekudzivirira fouling uye anti-stick, madiki kwazvo dynamic uye static friction coefficients, uye mashandiro akanaka ekudzivirira friction uye lubrication. Inoshandiswa se sealing pair yekuvhura nekuvhara butterfly valves, uye zvakakosha kuderedza sealing surface. Kukakavadzana pakati pe butterfly valves kunogona kuderedzwa, torque yekushanda ye butterfly valve inogona kuderedzwa, uye hupenyu hwebasa hwechigadzirwa hunogona kuvandudzwa.
Vharuvhu yeshavishavi ine fluorine, inozivikanwawo sevharuvhu remapuruguru rinodzivirira ngura, rinowanzoshandiswa mumamiriro ekushanda akaomarara, makemikari ane chepfu uye anokuvadza, kana kuti rinoparadza zvakanyanya mhando dzakasiyana dzeasidhi-base kana organic solvents. Kushandiswa zvisina kunaka kuchaita kuti pave nekurasikirwa kukuru kwehupfumi uye zvakakomba nekuda kweizvozvo. Kushandiswa nemazvo uye kugadziriswa kwevharuvhu remapuruguru kunogona kuwedzera hupenyu hwebasa revharuvhu remapuruguru rine fluorine, saka ndezvipi zvinhu zvinogona kuitwa kuti rinyatsochengetedzwa?
1. Usati washandisa, verenga bhuku remirayiridzo revharuvhu remashavishavi rine fluorine.
2. Ishandise mukati mehuwandu hwekumanikidzwa, tembiricha uye huwandu hwepakati hwakatsanangurwa papepa remazita kana mubhuku rekushandisa.
3. Kana uchiishandisa, dzivirira vharuvhu yeshavishavi ine fluorine kuti isanyanya kukonzera kushushikana kwepaipi nekuda kwekuchinja kwetembiricha, deredza kuchinja kwetembiricha, uye wedzera majoini ekuwedzera akaita seU vharuvhu yeshavishavi isati yatanga uye yapera.
4. Hazvibvumirwi kushandisa chibatiso kuvhura nekuvhara vharuvhu reshavishavi rine fluorine. Nyatsocherechedza nzvimbo yekuratidza kuvhura nekuvhara uye mudziyo wekudzivirira vharuvhu reshavishavi rine fluorine. Mushure mekunge kuvhura nekuvhara kwaiswa, usamanikidza vharuvhu kuti ivhare, kudzivirira kukuvara kusati kwasvika panzvimbo yekuvharira purasitiki yefluorine.
5. Kune mamwe ma media asina kugadzikana uye ari nyore kuora (semuenzaniso, kuora kwemamwe ma media kunokonzera kuwedzera kwehuwandu uye kukonzera kuwedzera kwekumanikidzwa mumamiriro ekushanda), izvo zvinozokonzera kukuvara kana kubuda kwevharuvhu rema butterfly, matanho anofanirwa kutorwa kubvisa kana kuderedza zvinhu zvinokonzera kuora kwe ma media asina kugadzikana. . Pakusarudza vharuvhu rema butterfly, vharuvhu rema butterfly rine fluorine rine mudziyo wekudzikisa kumanikidzwa otomatiki rinofanira kusarudzwa tichifunga nezvekuchinja kunogona kuitika mumamiriro ekushanda kunokonzerwa nekuora kusina kugadzikana uye kuri nyore kwe medium.
6. Kunevharuvhu yeshavishavi ine fluorinepapombi ine chepfu, inobvira moto, inoputika uye ine simba rinoparadza, zvinorambidzwa zvachose kutsiva kurongedza pasi pekumanikidzwa. Kunyangwe vharuvhu yeshavishavi ine fluorine ine basa rekuvhara repamusoro mukugadzirwa, hazvikurudzirwi kutsiva kurongedza pasi pekumanikidzwa.
7. Pamapaipi ane nzvimbo yekupisa inongoerekana yaitika, matanho anofanirwa kutorwa kuona kuti tembiricha yemhepo nemamiriro ekushanda hazvigone kudarika nzvimbo yekupisa inongoerekana yaitika yenzvimbo yekupisa kudzivirira njodzi inokonzerwa nezuva kana moto wekunze.
Nzira inoshandiswa: huwandu hwakasiyana hwemunyu weacid-base uye zvimwe zvinonyungudutsa zvakasikwa.
