3.Core Features
Wide Temperature Range Adaptability & Performance Stability: Mushure memaawa 1,800 e "-200℃~800℃" thermal cycle testation, kuvharwa kwekuita chisimbiso kwakaderera pane kana kuenzana ne3.8% - kusimba zvakapetwa kaviri kwematepi akajairwa ekuvharisa magirafu (ayo ane 12% kuderera kwekuita kuri pamusoro pe600). Hapana brittleness kana kutsemuka patembiricha yakaderera (10 kupetwa pa-200 madhigirii pasina kutyoka) uye hapana carbonization iri pakati-kupisa kwepamusoro, zvichiita kuti zvienderane nemamiriro akaita semapaipi munzvimbo dzinotonhora dzekuchamhembe (-40 madhigirii ), midziyo yekudzivirira chikafu chekudya (150 dhigirii dhigirii dhigirii) . Iyo yakawanda-yekushanda-mamiriro ekuisa chisimbiso kukundikana mwero wevatengi vepasi inoderedzwa ne85%.
Yakakwirira-Kunyatsovhara uye Kudzivirira kuvunza: Iyo yakasarudzika "arc-yakaita makora maumbirwo" (Corrugation kureba: 0.3-2.5mm, customizable) inowedzera nzvimbo yekubata yekuvharisa ne45%. Mushure me1,000 yepakati-yepamusoro-yepamusoro-yepamusoro yekuvharisa chisimbiso bvunzo (yakanyanya kudzvanywa ye18MPa), iyo leakage rate Ishoma pane kana kuenzana ne8 × 10⁻⁷ Pa·m³/s, inodarika nekure iyo Chinese National Standard GB/T 4622.3-2021 yekuvharika kwesealing leakage (Less than 1×⁵⁵ Pa·m³/s). Chiyero chekufanirwa kweflange chisimbiso chepetrochemical mapaipi chinosvika 99.4%.
Yakasimba Corrosion Resistance & Chemical Compatibility: Mushure memaawa 960 ekuedza kunyudzwa (asidhi-mishonga yepasi ine pH 2-13, organic solvents yakadai seacetone/ethylene glycol), uwandu hwekurasika hwakaderera pane kana kuenzana ne1.8%, pasina kuzvimba kana delamination. Inokodzera kuvhara chlorine{{6}iine mapaipi emvura yetsvina muindasitiri yekuchenesa mvura (chlorine corrosion resistance) uye isina kusimba acid-base media muindasitiri yemakemikari, hupenyu hwayo hwesevhisi hunowedzerwa kusvika kumakore 2-3, zvichienzaniswa nemagasket erabha (ayo ane nguva yekusaora kwemwedzi mitatu).
High Adaptability & Easy Processability: Hukobvu hunotangira pa 0.2-6mm (inogoneka), ine kamuri-tembiricha inoshanduka ichigonesa 300 kubhenda kutenderera pasina kutsemuka. Iyo ichiri kuchengetedza imwe elasticity pa800℃(compression rebound rate Yakakura kupfuura kana yakaenzana ne85%). Kuburikidza neCNC yekucheka kuyedzwa, kutsetseka kwemupendero mushure mekucheka muhukuru husingaenzaniswi (hupamhi hwepamusoro hwe1,500mm) uye zvisimbiso zvisimbiso (semuenzaniso, elliptical flanges) Ishoma pane kana kuenzana ne0.1mm. Inofambirana neinopfuura 96% yenzvimbo dzakajairwa dzekuvharisa maindasitiri (maflange, mavharuvhu, pombi), uye iko kushanda kwayo kwakakwira ne55% kupfuura iyo yechinyakare yekuisa chisimbiso gaskets.
4. Core Applications
Petrochemical Field(35% chikamu, chiitiko chikuru chekushandisa):Corrugated Graphite Sealing Tape inoshandiswa kunama mapaipi ekufambisa mafuta asina kuchena (-20 madhigirii ~80 madhigirii ) uye epakati-mapaipi ekutsemuka kwezvikamu (300 digiri ~500 madhigirii ). Zvinoenderana nedata rekuyedza kubva kuPetroChina Lanzhou Petrochemical, inogona kudzikisa kutadza kwepombi kubva pa6.1% kusvika 0.4%, uye kucheka mutengo wepagore wekugadzirisa chisimbiso chechikamu chimwe chete ne380,000 RMB. Inokodzera sulfur-ine yepakati mapaipi (hydrogen sulfide corrosion resistance), kuvimbika kwayo kwekuisa chisimbiso kunosangana nezvinodiwa zvekuenderera mberi kwekugadzirwa.
Mvura Yekurapa Munda(22% chikamu): Inoshandiswa sevharo yepombi dzecentrifugal mumapombi ekuchenesa tsvina (tembiricha yemumba, chlorine-ine mvura inoraswa) uye mapaipi maflange mumabasa emvura (-5℃~40 degree). Hupenyu hwesevhisi hwayo hunowedzerwa kusvika kumakore 2.5, zvichienzaniswa nerubha gaskets (inoda kuita ngura uye kuchembera neklorini), uye avhareji yekuisa chisimbiso kutsiva kutenderera kwemidziyo yemvura inowedzerwa kubva kumwedzi miviri kusvika kumwedzi gumi nemisere. Inopindirana neGB/T 17219-1998 Safety Standard yeDrinking Water Transmission and Distribution Equipment, isina zvinhu zvinokuvadza zvakanaya.
General Machinery Field(28% chikamu): Inoshandiswa kuvhara mavharuvhu e compressor (150 dhigirii ~ 300 dhigirii), kudhinda michina roller shafts (tembiricha yekamuri), uye machira emichina mabearings (50 dhigirii ~120 dhigirii). Inogadzirisa dambudziko remagaskets echinyakare ari kuda kupfeka uye anoda kugara achivharwa kuti atsive, achidzikisa huwandu hwakakwana hwekutadza kweyakajairwa michina michina ne42%. Inokwanisa kugadzika zvirinani pane magasi esimbi enzvimbo dzisina kuvharika (semuenzaniso,-mavharuvhu akaumbwa).
Food & Pharmaceutical Field(15% chikamu): Inoshandiswa kuvhara maflange ematangi ekudya sterilization (121 dhigirii, nharaunda yeutsi) uye mapaipi emishonga yekuomesa chando (-50℃~80 degree). Iyo inoenderana neFDA 21 CFR Chikamu 177.2600 yezvekudya zvekushandisa, isina kunhuhwirira kunhuhwirira kana kunaya kwetsvina pakupisa kwakanyanya, kuve nechokwadi chekudya uye hutsanana hwemishonga uye kuchengetedzeka. Zvinoenderana nemiedzo yakaitwa naMengniu Dairy, bvunzo dzese dzekutama dzegaskets dzinosangana nezviyero, zvichigutsa kutevedzera zvinodiwa pakugadzirwa kwechikafu.
