Hauv kev lag luam thiab kev ua neej txhua hnub, cov roj hmab hoses thiab nylon raj yog siv dav vim lawv cov khoom siv lub cev thiab tshuaj sib txawv. Cov roj hmab hoses yog lub npe nrov rau lawv qhov kev tiv taus zoo rau qhov kub siab thiab qis, kev ruaj khov tshuaj lom neeg, thiab kev ywj pheej zoo heev, thaum cov nylon raj tau txais kev nyiam rau lawv qhov kev tiv taus roj, kev cuam tshuam kub qis, thiab qhov sib dua. Tsab xov xwm no delves rau hauv qhov zoo thiab qhov tsis zoo ntawm ob hom raj thiab muab cov ntaub ntawv siv tau los muab cov lus qhia rau kev xaiv ntawm cov roj hmab hoses thiab nylon raj.
Cov Yeeb Nkab Roj Hmab
Cov txiaj ntsig:
- Kev Tiv Thaiv Kub thiab Qis: Cov roj hmab hoses tuaj yeem tiv taus qhov kub thiab txias ntawm -80 ° C txog 300 ° C, ua rau lawv haum rau qhov chaw kub heev.
- Kev Tiv Thaiv Tshuaj: Lawv ua kom pom tseeb tias lawv tiv taus ntau yam tshuaj lom neeg, tshwj xeeb tshaj yog cov roj, kua qaub, thiab alkali.
- Kev Tiv Thaiv UV thiab Ozone: Muaj peev xwm tiv taus UV hluav taws xob thiab kev yaig ozone, cov roj hmab hoses zoo tagnrho rau kev siv sab nraum zoov.
- Muaj Zog Elastic: Nrog rau qhov elasticity zoo, lawv tuaj yeem tiv taus kev sib txhuam thiab tsis yooj yim rau deformation.
- Kev Rwb Thaiv Hluav Taws Xob: Qee hom roj hmab hoses muaj cov khoom rwb thaiv hluav taws xob zoo heev, ua rau lawv haum rau kev lag luam hluav taws xob.
Qhov Tsis Zoo:
- Kev Tiv Thaiv Siab: Lawv qhov kev tiv thaiv siab yog qhov tsawg, yog li lawv tsis haum rau qhov chaw muaj kev kub siab.
- Kev Tiv Thaiv Dej Ntws: Phab ntsa sab hauv ntawm cov roj hmab hoses muaj qhov roughness siab, ua rau muaj kev tiv thaiv dej ntws tseem ceeb.
- Lub Neej Tiv Thaiv Kub: Lawv lub neej tiv taus kub luv heev.
Cov Ntaub Ntawv Siv: Vim lawv tiv taus tshuaj lom neeg thiab tiv taus kub, cov roj hmab hoses feem ntau siv rau hauv kev lag luam xws li tsheb, nkoj tsim, tshuaj lom neeg engineering, thiab roj av. Cov ntawv thov feem ntau suav nrog cov nplhaib sealing, gaskets, zaj duab xis, thiab khaub ncaws tiv thaiv.
Cov raj nylon
Cov txiaj ntsig:
- Kev Tiv Thaiv Roj thiab Tshuaj Lom Zem: Cov raj nylon muaj kev tiv thaiv zoo rau roj thiab tshuaj lom neeg, tshwj xeeb tshaj yog roj av, diesel, roj lubricating, thiab roj.
- Kev Tiv Thaiv Kub Qis: Piv txwv li, PA11 tuaj yeem tiv taus qhov kub qis ntawm -50 ° C, thiab PA12 tuaj yeem ua li ntawd ntawm -40 ° C.
- Lub Neej Ntev Uas Tiv Tau Kub: Piv nrog cov kav roj hmab, cov kav nylon muaj lub neej ntev dua uas tiv tau kub. Qhov kub ua haujlwm ntawm PA11 yog -40 ° C txog 125 ° C, thiab PA12 yog -40 ° C txog 105 ° C.
- Sab Hauv du: Sab hauv ntawm cov raj nylon du dua li cov raj roj hmab, ua rau tsis kam. Qhov roughness ntawm phab ntsa raj roj hmab yog 38μm, thaum ntawm cov raj nylon tsuas yog 2.5μm.
- Lub teeb yuag: Cov raj nylon muaj qhov ceev tsawg, kwv yees li 1/7 ntawm cov hlau thiab tooj liab, uas tuaj yeem txo qhov hnyav tag nrho ntawm cov tsheb.
- Kev Tiv Thaiv Corrosion: Lawv muaj cov yam ntxwv tiv thaiv corrosion, tiv thaiv kev laus, qhov chaw du, thiab yooj yim sib dhos.
Qhov Tsis Zoo:
- Kev Nqus Dej: Cov raj nylon feem ntau yuav nqus dej, uas cuam tshuam rau qhov tseeb ntawm cov khoom.
- Kev Tiv Thaiv Lub Teeb Tsis Zoo: Hauv qhov chaw kub siab, cov raj nylon yooj yim rau oxidation, ua rau xim av thiab tawg.
- Kev Tsis Haum Rau Acid Thiab Oxidant: Lawv tsis tuaj yeem siv ua cov ntaub ntawv uas tiv taus acid thiab tsis tiv taus cov oxidants.
Cov Kev Siv: Vim lawv lub zog tsis hnyav thiab tiv taus tshuaj lom neeg, cov raj nylon siv dav hauv cov kav dej roj tsheb. Lawv tuaj yeem txo qhov hnyav thiab tus nqi ntawm tag nrho lub tsheb thiab ua kom cov kav dej roj zoo ib yam. Hauv cov khoom siv hauv tsev, cov raj nylon kuj siv ua cov kav dej nkag thiab tawm, cov tes tsho tiv thaiv rwb thaiv tsev, cov raj tiv thaiv hluav taws, lossis cov kav dej ntws, vim lawv tiv taus xeb thiab ua haujlwm rwb thaiv tsev zoo heev.
Xaus lus, cov yeeb nkab roj hmab thiab cov yeeb nkab nylon txhua tus muaj lawv tus kheej qhov zoo. Kev xaiv yuav tsum yog raws li kev txiav txim siab txog cov kev cai thov tshwj xeeb, cov peev nyiaj siv, cov xwm txheej ib puag ncig, thiab cov txheej txheem xav tau. Txhua yam khoom siv muaj nws lub zog thiab kev txwv tshwj xeeb, ua rau lawv haum rau ntau qhov xwm txheej thov.
