PTFE rau ntim yog nyob deb ntawm cov khoom siv dav tshaj plaws hauv txhua hom kev ua zaub mov thiab dej haus, suav nrog tab sis tsis txwv rau cawv, npias, khoom noj siv mis, dab, syrups thiab seasonings, hnyuv ntxwm, chocolate thiab cov nqaij tiav lawm -Siv PTFE rau conveying thiab tuav cov khoom siv.
Cov khoom zoo hauv qab no ua rau PTFE hose sib dhos ntau yam. PTFE yog chemically inert; txawm tias dhau tag nrho cov kev khiav hauj lwm kub ntawm -60 degree rau ntxiv rau 260 degree, lub hose yuav tsis cuam tshuam rau cov khoom xa tuaj txhua txoj kev. Nws tsis muab cov xim, saj lossis tsw rau cov zaub mov. PTFE tsis nqus los yog tshem tawm cov khoom xyaw, tsis txawm ya raws. PTFE muaj qhov coefficient tsis tshua muaj kev sib txhuam; qhov no txhais tau hais tias cov zaub mov tsis lo, residue tsis tsim, thiab nws yooj yim, ceev, thiab, qhov tseem ceeb tshaj, tu cev kom huv.
Qhov no yuav pab txo cov nqi tu cov cuab yeej, nce lub sijhawm ua haujlwm, nce cov txiaj ntsig thiab tswj cov khoom purity.
Ua ke cov khoom no ua rau PTFE ua ntau yam khoom siv hose rau kev lag luam khoom noj. Tsis muaj lwm cov khoom siv hose siv rau ntau daim ntawv thov lossis tshem tawm ntau yam teeb meem hauv kev nyab xeeb thiab ua zaub mov. Cov yam ntxwv paub zoo txog PTFE hose tau pom zoo los ntawm Food and Drug Administration.
PTFE Properties thiab Cov txiaj ntsig
Inert rau txhua yam khoom noj thiab dej haus thiab yuav luag txhua yam tshuaj paub
Tsis yog-stick thiab yooj yim los ntxuav vim paub tias tsis tshua muaj coefficient ntawm kev sib txhuam; tiv thaiv kev nqus ntawm cov tshuaj ntxuav tu (CIP, COP)
Permanently resistant rau chav sterilization
Muaj peev xwm tuav tau ntau yam kev hloov pauv kub: -60⁰C txog 260⁰C
tsawg heev permeability
Non-reactive, tsis muaj corrosion los ntawm cov khoom los yog extractables paug cov txheej txheem; yog li ntawd, tsis muaj kev hloov hauv saj, tsw lossis xim
Microbial tsis kam
FDA pom zoo thiab USP CLASS VI Ua raws
Yuav siv tau nrog FDA pom zoo cov pa roj carbon monoxide tso cai rau electrostatic paug
zoo pob tshab
Muaj zog khoov qaug zog kuj
lub neej ntev dua
