Yas, roj hmab, seals
Cov khoom sib txawv
Yas thiabroj hmabyog ob hom khoom sib txawv nrog qee qhov sib txawv hauv lawv cov khoom, khoom siv, thiab kev siv.
- Cov Khoom Siv: Cov yas yog tsim los ntawm cov khoom siv hluavtaws, thaum cov roj hmab yog tsim los ntawm cov khoom siv hluavtaws lossis hluavtaws polymer.
- Cov ntaub ntawv raw: Cov khoom siv raw ntawm cov yas tuaj yeem yog cov roj fossil xws li roj, nkev roj, thee, thiab lwm yam, thiab cov polymers yog synthesized los ntawm cov tshuaj tiv thaiv. Cov khoom siv raw ntawm cov roj hmab tuaj yeem yog cov latex ntawm cov ntoo roj hmab (natural rubber) lossis hluavtaws roj hmab (synthetic rubber).
- Lub cev muaj zog: Cov yas feem ntau yog tawv thiab nkig, nrog cov khoom zoo rwb thaiv tsev, corrosion kuj thiab moldability. Roj Hmab muaj cov khoom elastic thiab mos thiab tuaj yeem rov qab mus rau nws cov duab qub tom qab ncab. Nws kuj muaj qhov hnav tsis kam thiab tsim kua muag.
- Kev Siv: Vim muaj cov khoom sib txawv thiab cov yas yas, lawv tau siv dav hauv kev tsim khoom ntawm ntau yam khoom, xws li cov hnab yas, lub raj mis yas, cov kav dej yas, cov rooj tog yas, thiab lwm yam. Vim nws elasticity thiab hnav tsis kam, roj hmab yog dav. siv rau hauv kev tsim cov log tsheb, cov ntsaws ruaj ruaj, roj hmab raj, khau roj hmab, thiab lwm yam.
Nws yuav tsum tau taw qhia tias tseem muaj cov khoom hu ua thermoplastic elastomers (TPE), uas muaj cov yam ntxwv ntawm ob qho tib si yas thiab roj hmab. TPE tuaj yeem ua kom sov, yaj thiab txhaj tshuaj molded zoo li yas, thaum muaj elasticity thiab softness ntawm roj hmab. Cov khoom siv no tuaj yeem hloov cov khoom siv yas lossis roj hmab ib txwm siv hauv ntau daim ntawv thov.
Plastic seals thiab roj hmab foob yog ob hom kev foob uas muaj qee qhov sib txawv ntawm cov khoom, khoom, thiab kev siv.
- Khoom siv: Yas seals feem ntau yog siv cov ntaub ntawv polymer, xws li polypropylene (PP), polyethylene (PE), polyvinyl chloride (PVC), thiab lwm yam. Cov ntsaws ruaj ruaj yog siv cov khoom siv roj hmab, xws li styrene-butadiene roj hmab (BR), nitrile-butadiene roj hmab. (NBR), fluorine roj hmab (FKM), thiab lwm yam
- Sealing kev ua tau zoo: Vim tias roj hmab muaj elasticity zoo thiab yas, cov roj hmab ntsaws ruaj ruaj tuaj yeem muab kev sib khi zoo, muaj kev ua haujlwm siab elastic rov qab, thiab tuaj yeem hloov mus rau qhov loj deformations thiab tsis sib xws. Yas seals muaj qhov ua tau zoo sealing tsis zoo thiab feem ntau haum rau qhov tsis tshua muaj siab, tsis tshua muaj kub, lossis cov ntawv thov uas tsis tas yuav tsum muaj kev sib khi zoo.
- Durability: Roj Hmab cov ntsaws ruaj ruaj muaj zoo hnav tsis kam, corrosion kuj thiab aging kuj, thiab yuav siv tau ntev nyob rau hauv ib puag ncig hnyav. Hauv qhov sib piv, cov ntsaws ruaj ruaj yas tsis tshua muaj zog thiab muaj kev cuam tshuam rau corrosion thiab hnav los ntawm cov tshuaj.
- Scope ntawm daim ntawv thov: Vim lub elasticity zoo heev thiab durability ntawm roj hmab seals, lawv tau dav siv nyob rau hauv high-pressure, high-temperature thiab cov xwm txheej uas yuav tsum tau ntau dua sealing kev ua tau zoo, xws li automotive engine, piping systems, hydraulic khoom, thiab lwm yam. Feem ntau yog siv rau hauv cov xwm txheej uas tsis tshua muaj siab, tsis tshua muaj kub thiab kev sib khi dav dav, xws li cov khoom siv hauv tsev, cov khoom siv niaj hnub, cov kav dej tsis tshua muaj siab, thiab lwm yam.
Nws yuav tsum raug sau tseg tias kev xaiv tshwj xeeb ntawm cov yas los yog roj hmab foob kuj nyob ntawm cov yam ntxwv xws li cov ntawv thov tshwj xeeb, ib puag ncig ua haujlwm thiab nyiaj txiag. Qee qhov tshwj xeeb, cov ntsaws ruaj ruaj uas ua los ntawm cov khoom sib xyaw lossis lwm yam khoom tshwj xeeb kuj tseem siv tau los ua kom tau raws li cov kev xav tau tshwj xeeb.
