Cov chaw tsim khoom siv kho mob yeej ib txwm nrhiav kev txhim kho lawv cov qauv tsim khoom siv kom ua rau lawv cov kev ua tau zoo dua. Muaj ntau yam sib txawv hauv kev lag luam khoom siv kho mob uas cov chaw tsim khoom yuav tsum xav txog thaum coj cov khoom mus rau kev ua lag luam. Ib qho ntawm cov qauv feem ntau hauv kev lag luam khoom siv kho mob yog kev txuas cov hlau thiab yas. Lwm qhov yog kom cov ntaub ntawv "lub sijhawm tiag tiag" mus txog rau lub kaw lus kuaj mob. Cov chaw tsim khoom siv kho mob yeej ib txwm txav mus los tsim cov khoom zoo tshaj plaws kom tau raws li cov qauv tshiab thiab kev xav tau kev kho mob.
Ntxiv mus, cov chaw tsim khoom siv kho mob raug khi los ntawm cov cai nruj uas FDA tau siv. Cov khoom siv kho mob tau muab faib ua peb pawg, I-III. Cov khoom siv kho mob Pawg III yog cov uas raug tswj hwm ntau tshaj plaws. Ntxiv rau cov qauv kev cai lij choj dav dav, cov chaw tsim khoom siv kho mob yuav tsum txhawj xeeb txog qhov ua tau zoo ntawm lawv cov khoom siv vim tias lawv tuaj yeem nkag mus rau hauv tib neeg. Cov khoom siv kho mob uas tsis zoo tuaj yeem tua ib tus neeg. Hmoov tsis zoo, cov chaw tsim khoom siv kho mob yuav raug foob yog tias nws cov khoom siv tsis ua haujlwm thiab ua rau muaj kev phom sij. Qhov zoo ntawm cov khoom yog qhov tseem ceeb rau cov chaw tsim khoom siv kho mob.
Vim muaj cov teeb meem no, cov chaw tsim khoom siv kho mob yuav tsum siv cov khoom zoo tshaj plaws, yog vim li cas lawv thiaj li siv feem ntauPTFE tuberaws li lawv xaiv rau lub dab da deje. PTFE yog ib qho fluoropolymer uas tau muaj nyob ib puag ncig rau qee lub sijhawm. Yog tias koj tau hnov txog ptfe raj, qhov no yog qhov peb tab tom tham txog thaum peb hais txog PTFE. Ib qho fluoropolymer yog ib qho tshuaj lom neeg uas muaj ntau yam fluorocarbons.
Muaj ntau yam ntxwv uas ua rauPTFE tubesawv tawm. Ua ntej tshaj plaws, ib yam li txhua yam fluoropolymers, PTFE muaj cov yam ntxwv tsis lo. Qhov no yog vim li cas nws feem ntau siv rau cov khoom siv ua noj. PTFE kuj tsis muaj zog rau feem ntau cov tshuaj lom neeg, yog li cov chaw tsim khoom tsis tas yuav txhawj txog cov tshuaj tsis zoo. PTFE muaj qhov sib txhuam qis tshaj plaws ntawm txhua yam polymer. Nws muaj qhov kub thiab txias siv tau ntau ntawm 500 degrees Fahrenheit, thiab nws muaj cov khoom siv hluav taws xob zoo heev. Nws kuj tiv taus hluav taws xob UV thiab huab cua.
Cov chaw tsim khoom siv kho mob siv PTFE tubing rau ntau yam kev siv. Nws tseem yog fluoropolymer xaiv rau cov chaw tsim khoom siv hluav taws xob, cov chaw tsim khoom tsheb, thiab ntau ntxiv. PTFE tubing yog ib qho ntawm ntau hom fluoropolymer tubing.emuaj nyob ntawm no ntawm Fluorotherm. Peb xav kom koj mus saib peb cov khoom muag kom paub meej ntxiv txog cov fluoropolymer twg zoo tshaj plaws rau koj txoj haujlwm thiab daim ntawv thov.
