Kev tsim cov txheej txheem ntawm PTFE corrugated hose
May 01, 2026
PTFE corrugated kav, uas yog ib qho tseem ceeb nyob rau hauv cov kav dej systems, undergo ib tug series ntawm ua cov kauj ruam los ntawm raw khoom npaj mus rau qhov kawg khoom tsim.
Cov txheej txheem tsim khoom pib nrog kev xaiv qib siab - zoo PTFE cob ua cov khoom siv raw, ua kom nws cov purity, molecular hnyav, thiab uniformity raws li qhov yuav tsum tau muaj. Cov txheej txheem cov khoom xav tau PTFE resin purity ntawm 99.9% lossis siab dua thiab cov ntsiab lus hlau impurity tswj qis dua 50 ppm. Lub PTFE resin yog ces qhuav kom tshem tawm cov dej noo thiab ua kom muaj kev ruaj ntseg. Yog tias tsim nyog, PTFE resin tuaj yeem sib xyaw nrog cov khoom siv ntxiv thiab granulated siv cov khoom siv.
Cov pre-kho PTFE granules yog pub rau hauv extruder thiab yaj-extruded nyob rau hauv kub thiab siab mus rau hauv ib tug nruam tubular preform. Thaum lub sij hawm extrusion, kub, siab, thiab ceev yuav tsum tau nruj me ntsis tswj kom lub uniformity thiab seem raug ntawm lub preform. Lub extruded preform yuav tsum tau txias sai thiab zoo li tus los tiv thaiv deformation.
Sab hauv thiab sab nrauv ntawm lub preform yog polished kom tshem tawm burrs thiab qhov chaw tsis sib xws, txhim kho nto smoothness. Cov kuab tshuaj tsim nyog lossis cov txheej txheem ntxuav yog siv los tshem tawm cov roj, plua plav, thiab lwm yam impurities los ntawm preform nto.
Dhau li ntawm extrusion molding, PTFE corrugated kav kuj tuaj yeem tsim los ntawm lwm txoj kev. Piv txwv li, PTFE resin tuaj yeem ua ntej- tsim los ntawm kev sib xyaw nrog cov roj nplua nyeem, ua raws li extrusion, siab - nrawm nrawm ntawm qhov kub hauv qab lub melting point, thiab qhov kub ntawm qhov kub siab tshaj qhov melting point kom tau txais cov khoom kawg. Lwm txoj kev muaj xws li kub nias, machining, stretch forming, thiab stretch spiral forming.
Qhov kev ncaj ncees thiab kev sib haum xeeb ntawm cov yeeb nkab corrugated yog cuam tshuam los ntawm cov khoom xws li winding nro, zaj duab xis thickness, sintering kub, thiab lub sij hawm. Cov txheej txheem no yuav tsum tau tswj nruj me ntsis kom ntseeg tau qhov zoo.
