- Kev ua haujlwm zawv zawg: Nws muaj qhov sib txhuam coefficient tsawg heev thiab nws tus kheej lubricating zog, thiab feem ntau yog siv rau hauv cov txheej tsis lo thiab zawv zawg qhov chaw.
2. Roj hmab
Structure: Roj hmab yog polymerized los ntawm ntau hom monomers (xws li butadiene, isoprene, thiab lwm yam), thiab cov saw molecular muaj qhov yooj thiab elasticity.
Basic Properties:
Elasticity: Nws tuaj yeem deform thiab rov qab mus rau nws cov duab qub tom qab kev ntxhov siab, thiab muaj qhov elongation siab thaum so.
Qhov kub thiab txias: Cov roj hmab sib txawv muaj qhov sib txawv ntawm qhov kub thiab txias, uas feem ntau qis dua PTFE.
Hnav tsis kam thiab tsim kua muag ua haujlwm: Kev hnav tsis kam thiab tsim kua muag zoo heev.
Lub cev muaj zog
1. PTFE
- Hardness thiab brittleness: siab hardness thiab muaj zog brittleness, nrog zoo hnav tsis kam.
- Opacity: feem ntau translucent los yog opaque.
- Hluav taws xob rwb thaiv tsev: zoo heev hluav taws xob rwb thaiv tsev kev ua tau zoo, feem ntau siv nyob rau hauv cables thiab rwb thaiv tsev qhov chaw.
2. Roj hmab
- Flexibility: Nws muaj qhov yooj yooj yim thiab elasticity thiab tuaj yeem hloov mus rau qhov loj deformations.
- Transparency: Nws pob tshab tuaj yeem hloov kho raws li qhov xav tau tshwj xeeb.
- Rwb thaiv tsev: Nws feem ntau kuj muaj cov hluav taws xob rwb thaiv tsev zoo thiab tsim nyog rau kev khoov thiab kev sib khi zoo dua.
Daim ntawv thov teb
1. Daim ntawv thov ntawm PTFE
Kev siv tshuaj lom neeg thiab khoom noj khoom haus: Nws cov khoom tiv thaiv corrosion thiab cov khoom tsis yog nplaum ua rau nws siv dav hauv cov kav dej, cov ntsaws ruaj ruaj, thiab cov txheej tsis-stick.
Kev kho mob thiab bioengineering: Hauv kev cog qoob loo thiab cov khoom siv kho mob, PTFE tau txais txiaj ntsig rau nws cov tshuaj lom neeg ruaj khov thiab kev sib raug zoo.
Hluav taws xob thiab hluav taws xob: Nws zoo heev hluav taws xob rwb thaiv tsev thiab high-temperature kuj ua rau nws yog ib qho zoo tagnrho xaiv rau cable rwb thaiv tsev, connectors, thiab cov khoom cua kub dissipation.
2. Kev siv roj hmab
Tsheb thiab aerospace: ntsaws ruaj ruaj, roj hmab shock absorbers, log tsheb, thiab cables. Lub elasticity thiab hnav tsis kam ntawm cov ntaub ntawv roj hmab ua rau lawv ua tau zoo nyob rau hauv ib puag ncig zoo li no.
Kev tsim kho thiab kev tsim vaj tsev hauv vaj tse: siv rau cov khoom siv dej tsis zoo, cov roj hmab gaskets, thiab cov khoom siv cais tawm seismic, uas tuaj yeem muab kev sib khi zoo thiab tsis zoo.
Cov khoom siv thiab cov khoom lag luam: xws li cov ntsaws ruaj ruaj, gaskets, hnab looj tes, thiab lwm yam, yog siv dav hauv cov khoom siv niaj hnub thiab cov khoom siv hauv tsev.
Economic thiab sustainable
1. Economicalness ntawm PTFE
Tus nqi siab: Cov txheej txheem ntau lawm ntawm PTFE yog qhov nyuaj thiab cov ntaub ntawv raw kuj tseem kim, uas ua rau nws kim dua. Nws feem ntau yog siv nyob rau hauv high-end teb nrog tshwj xeeb yuav tsum tau.
Sustainability: Txawm hais tias PTFE muaj irreplaceable yam ntxwv ntawm tej lub sij hawm, nws cov ntau lawm thiab pov tseg muaj peev xwm cuam tshuam rau ib puag ncig.
2. Economic Efficiency ntawm Roj Hmab
Tus nqi-kev ua tau zoo: Roj hmab feem ntau muaj cov khoom siv qis thiab cov cuab yeej ua tiav, uas ua rau nws siv dav hauv cov neeg siv khoom loj thiab kev lag luam yooj yim.
Sustainability: Cov roj hmab ntuj thiab qee cov roj hmab hluavtaws yog biodegradable, thiab kev nce qib ntawm kev tsim ntsuab thiab kev siv thev naus laus zis tau txhim kho nws txoj kev ruaj khov.
Xaus
Thaum xaiv PTFE thiab roj hmab, tus yuam sij yog kom phim cov kev thov tshwj xeeb. PTFE yog haum rau huab cua puag ncig thiab tshwj xeeb yuav tsum tau nrog nws unparalleled tshuaj stability thiab siab-temperature kam rau ua, thaum roj hmab yog ib tug zoo tagnrho cov ntaub ntawv rau ntau yam kev siv nrog nws zoo elasticity thiab nqi-zoo. Kev nkag siab txog cov yam ntxwv ntawm ob cov ntaub ntawv no thiab lawv qhov sib txawv ntawm daim ntawv thov tuaj yeem pab ua kom muaj kev tshawb fawb ntau dua thiab kev xaiv tsim nyog thaum tsim thiab tsim khoom.
