Cov evolution ntawm Polytetrafluoroethylene (PTFE) - los ntawm ib tug niche khoom siv tsuas yog nyob rau hauv high-value daim ntaub ntawv mus rau lub mainstream yuav tsum tau maj mam heev.
Txawm li cas los xij, ob xyoo dhau los PTFE kev siv zoo li tau hla qhov loj loj, tso cai rau nws los ua lag luam nyob hauv ntau dua 200 kev lag luam, cov neeg siv khoom thiab kev siv kho mob.Thiab thaum nplooj ntawv, rods, coatings thiab Cheebtsam kaum feem ntau ntawm kev ua lag luam rau PTFE cov khoom, PTFE raj thiab PTFE hose yog tam sim no tshwm sim raws li qhov tseem ceeb ntawm kev loj hlob cheeb tsam.
PTFE tube siv
Kev siv ntawmPTFE cevtau kis thoob plaws ntau yam kev siv xws li tsheb, tshuaj, hluav taws xob thiab kev kho mob.Daim duab 1 qhia txog cov khoom tseem ceeb uas qhia txog kev ua tau zoo ntawm PTFE raj, thaum daim duab 1 qhia nws siv ntau yam.
Hauv kev siv tsheb, lub peev xwm ntawm PTFE tuaj yeem tiv taus qhov kub siab tshaj 250 ° C ua rau nws yog ib tus neeg sib tw zoo tshaj plaws rau kev hloov pauv dej kub.
Hauv kev siv tshuaj kho mob,PTFE cevyog nyob rau hauv loj thov vim nws lubricity thiab tshuaj inertness.Catheters siv PTFE raj tuaj yeem muab tso rau hauv tib neeg lub cev yam tsis muaj kev ntshai ntawm cov tshuaj tiv thaiv lossis kev puas tsuaj nrog txhua lub cev.
Hauv kev siv tshuaj lom neeg - suav nrog cov chaw soj nstuam - PTFE yog qhov zoo tagnrho hloov rau iav vim nws inertness thiab durability.
Hauv kev siv hluav taws xob, qhov zoo tshaj plaws dielectric zog ntawm nkauj xwb PTFE ua rau nws zoo haum rau insulating high voltage cables.
Hom PTFE raj
Nyob ntawm daim ntawv thov, PTFE raj tau muab faib ua peb pawg dav - txhua tus txhais los ntawm lub raj txoj kab uas hla thiab phab ntsa tuab (saib Daim duab 2).
Txawm nyob rau hauv pawg, PTFE raj qiv nws tus kheej mus rau txawv variations, txhua tus tso cai rau ib tug txawv daim ntawv thov (saib Table 3):
PTFE raj hauv khw muag khoom kho mob
Feem ntau, me me txoj kab uas hla spaghetti raj yog siv rau hauv daim ntawv thov kev kho mob.Kev siv PTFE hauv cheeb tsam no yog ob qho tseem ceeb: lubricity thiab biocompatibility.Fluoropolymers muaj lubricity zoo heev piv nrog rau lwm cov yas.PTFE yog lub lubricated polymer tshaj plaws muaj, nrog cov coefficient ntawm kev sib txhuam ntawm 0.1, ua raws li fluorinated ethylene propylene (FEP), nrog 0.2.Ob lub polymers no sawv cev rau feem coob ntawm tag nrho cov fluoropolymer raj siv hauv cov khoom siv kho mob.
Lub biocompatibility ntawm ib qho polymer siv hauv cov cuab yeej kho mob yog qhov kev txhawj xeeb pom tseeb.PTFE ua tau zoo hauv cheeb tsam no thiab muaj keeb kwm ntev ntawm kev siv vivo.Kev kho mob-qib fluoropolymers yuav tsum ua tau raws li USP Chav Kawm VI thiab ISO 10993 cov kev cai xeem.Tau kawg, kev ua kom huv si kuj yog ib qho tseem ceeb.
Tshaj li 18 xyoo dhau los, Besteflon txuas ntxiv tsom mus rau kev tsim cov PTFE Tubes thiab PTFE hose.Raws li cov pioneers hauv cheeb tsam ntawm fluoroplastics manufacturing, peb nrhiav qhov zoo tshaj plaws thiab kev pab cuam tom qab muag.Yog hais tias koj xav pib customizing PTFE raj rau koj daim ntawv thov tshwj xeeb, thov koj xav tiv tauj peb!
