Qhov tseem ceeb, qhov sib txawv tsuas yog nyob hauv lub npe. PTFE yog lub npe luv ntawm cov tshuaj polytetrafluoroethylene , thiab Teflon yog lub npe lag luam ntawm lub tib yam polymer. Yog tias koj tab tom nrhiav rau cov khoom siv tau yooj yim, tsis yog cov khoom siv uas yog tshuaj lom neeg, hluav taws xob thiab thermal resistant, saib tsis pub dhau. PTFE.
Yog li ntawd, PTFE puas yog Teflon?
PTFE , npe Teflon . Polytetrafluoroethylene (PTFE ) yog ib qho hluavtaws fluoropolymerof tetrafluoroethylene uas muaj ntau yam kev siv rau ntau daim ntawv thov xws li kev siv PTFE Daim kab xev. PTFE yog afluorocarbon khoom, raws li nws yog ib tug high-molecular-yuag compound uas muaj tag nrho cov carbon thiab fluorine.
Ib yam li ntawd, dab tsi yog lub monomer ntawm Teflon? Science qab Teflon Teflon yog ib tug polymer, uas yog tsim los ntawm kev sib koom ua ke ntau ntawm me me molecules hu ua cov monomers . Hauv qhov no, lub monomer yog tetrafluoroethene (TFE), thiab thaum polymerised nws ua poly-TFE, los yog PTFE raws li qee zaum hu ua.
Tom qab ntawd, ib tus tuaj yeem nug, puas yog PTFE tib yam li PFOA?
PFOA , PTFE thiab qhov sib txawv ntawm Ob PFOA , luv luv rau perfluorooctanoic acid, yog asynthetic compound uas muaj ntau yam kev siv. Nws yog lub npe hu rau repelwater thiab roj thiab yog siv nyob rau hauv cov txheej txheem ntawm ib co PTFE cookware. PTFE , ib yam khoom sib txawv, yog asynthetic polymer.
Puas yog PTFE muaj kev nyab xeeb?
Ingestion ntawm PTFE tsis tau tshaj tawm tias yog tshuaj lom thiab residual PFOA hauv PTFE -coated lauj kaub yog me me hloov mus rau zaub mov. Txawm li cas los xij, kev tshawb fawb ntev mus rau PTFE -fumesand PFOA tsis tau ua tiav yog li peb tsis tuaj yeem hais tias nws ua tiav nyab xeeb . Txawm li cas los xij, koj yuav tsum khaws Larry tus noog kom deb ntawm chav ua noj.

Feem ntau, lawv poob qhov chaw ntawm 15 "thiab 19", nrog rau cov chav dej hauv qab 17 ". Txawm li cas los xij, lub rooj zaum qhov siab hauv chav dej, dab tsi Kohler hais txog Comfort Height® chav dej, ntsuas 17 "los yog ntau dua
Dab tsi yog tib neeg engineering thiab tib neeg yam xwm txheej thiab ergonomics cuam tshuam li cas?
Ergonomics (lossis tib neeg yam tseem ceeb) yog kev qhuab qhia kev tshawb fawb txog kev nkag siab ntawm kev sib cuam tshuam ntawm tib neeg thiab lwm yam hauv lub cev, thiab kev ua haujlwm uas siv txoj kev xav, cov hauv paus ntsiab lus, cov ntaub ntawv thiab cov txheej txheem los tsim kom zoo rau tib neeg kev noj qab haus huv thiab kev ua haujlwm tag nrho

Vim li cas nws tseem ceeb los txiav cov plasmid thiab tib neeg DNA nrog tib yam kev txwv enzyme?
Cov enzymes no tseem ceeb vim tias lawv tso cai rau cov noob tshwj xeeb txiav tawm ntawm qhov chaw chromosome. Lawv kuj txiav cov kab mob plasmids. Siv tib yam kev txwv endonuclease enzyme los txiav qhib lub plasmid raws li yog siv los txiav cov noob los ntawm cov chromosome tau ua tiav cov nplaum nplaum uas tsim tawm
