Txoj kev roj hmabyog ib hom roj hmab thiab hlau lossis cov khoom siv fiber sib xyaw ua ke ntawm lub nplhaib roj hmab siv, feem ntau yog tsim rau cov tshuab ua liaj ua teb, cov tshuab tsim kho thiab cov tsheb thauj khoom thiab lwm yam khoom taug kev.

Cov xwm txheej ntawm cov khoom siv raw khoom ntws los

Lubtxoj kev roj hmabmuaj plaub ntu: kub kub, txheej ruaj khov, txheej buffer thiab roj hmab. Ntawm lawv, cov roj hmab suav nrog cov kua nplaum sab qauv, kua nplaum primer, kua nplaum hlau hlua, kua nplaum txheej cushion, kua nplaum txheej ntaub, kua nplaum hniav, kua nplaum sab log.

Kub tseem ceeb yog qhov sib kis, lub zog kis, kev taw qhia thiab kev txhawb nqa sab, cov ntaub ntawv tseem ceeb siv yog hlau ductile, hlau cam khwb cia wrought, txhuas alloy, hlau alloy phaj, thiab lwm yam, qee qhov kev khiav tuaj yeem siv yas.

Cov txheej muaj zog yog qhov chaw rub, uas yog lub cev ntev ntawm txoj kev roj hmab, uas tiv taus lub zog rub thiab tswj kev ruaj khov ntawm txoj kev. Cov ntaub ntawv tseem ceeb siv yog cov hlua hlau, cov hlua hlau galvanized, cov hlua hlau tsis xeb, cov iav fiber, aramid lossis lwm yam hlua hlau lossis cov hlua uas muaj zog siab thiab tsis ntev.
Cov txheej txheem buffer raug kev co thiab kev poob siab ntawm lub cev siv, thiab tiv taus ntau qhov kev hloov pauv los ntawm cov zog radial, lateral thiab tangential thaum lub sijhawm tsav tsheb. Tib lub sijhawm, nws tseem yog ib txheej tiv thaiv ntawm cov khoom siv traction, uas tiv thaiv cov khoom siv traction los ntawm kev puas tsuaj los ntawm cov zog sab nraud thiab tiv thaiv kev sib txhuam ntawm cov hlau hlau ntawm cov txheej muaj zog los ntawm cov tub ntxhais kub. Cov ntaub ntawv tseem ceeb siv yog nylon cord, nylon canvas thiab lwm yam khoom siv fiber.

Lubib feem roj hmabNws sib xyaw ua ke lwm yam khoom ua ke ua ib qho tag nrho, muab kev taug kev thiab kev tiv thaiv tag nrho, kev nqus dej poob siab thiab txo suab nrov, cov khoom siv tseem ceeb feem ntau yog roj hmab ntuj (NR) raws li NR / styrene-butadiene roj hmab (SBR), NR / SBR / cis-butadiene roj hmab (BR), NR / yaj polystyrene-butadiene roj hmab (SSBR) / BR thiab NR / BR ua ke system thiab polyurethane elastomer.

Cov neeg muab khoom siv raw khoom xws li roj hmab thiab hlau hlau feem ntau yog los ntawm Tuam Tshoj thiab Southeast Asia, Tebchaws Europe, Tebchaws Meskas thiab lwm thaj chaw muaj peev txheej nplua nuj.
