Roj hmab khiavyog ib hom roj hmab thiab hlau lossis fiber ntau cov khoom sib xyaw ntawm lub nplhaib roj hmab siv, feem ntau yog tsim rau cov tshuab ua liaj ua teb, kev tsim kho tshuab thiab tsheb thauj mus los thiab lwm qhov chaw taug kev.

Upstream raw khoom raws li txoj cai

Covroj hmab khiavyog tsim los ntawm plaub ntu: core kub, txheej muaj zog, tsis txheej thiab roj hmab. Ntawm lawv, cov roj hmab ib feem muaj xws li qauv sab kua nplaum, primer kua nplaum, steel qaum kua nplaum, cushion txheej kua nplaum, daim ntaub txheej kua nplaum, cov nplaum nplaum, lub log sab kua nplaum.

Tub ntxhais kub yog ib qho kev sib kis kabmob, kev xa hluav taws xob, kev taw qhia thiab kev txhawb nqa sab nraud, cov ntaub ntawv tseem ceeb siv yog cov hlau cam, cam khwb cia hlau wrought steel, aluminium alloy, alloy steel phaj, thiab lwm yam., qee qhov lem tuaj yeem siv cov yas.

Cov txheej txheem muaj zog yog qhov towing, uas yog lub longitudinal tensile lub cev ntawm cov roj hmab khiav, uas tiv taus lub zog traction thiab tswj kev ruaj ntseg ntawm kev khiav suab. Cov ntaub ntawv tseem ceeb siv yog steel hlua, galvanized steel hlau, stainless hlau xaim, iav fiber ntau, aramid los yog lwm yam high-strength low-elongation hluavtaws fiber cord ( hlua) los yog qaum.
Cov txheej tsis yog yuav muaj zog vibration thiab poob siab ntawm lub cev siv, thiab tiv taus ntau yam deformations tshwm sim los ntawm radial, lateral thiab tangential rog thaum tsav tsheb. Nyob rau tib lub sij hawm, nws kuj yog ib qho kev tiv thaiv txheej ntawm traction qhov chaw, uas tiv thaiv cov traction qhov chaw los ntawm kev puas tsuaj los ntawm sab nraud quab yuam thiab tiv thaiv kev sib txhuam ntawm cov hlau hlau ntawm lub zog txheej los ntawm cov tub ntxhais kub. Cov ntaub ntawv tseem ceeb siv yog nylon qaum, nylon canvas thiab lwm yam ntaub ntawv fiber ntau.

Covroj hmab ib feemZoo sib xyaw ua ke nrog lwm cov khoom xyaw rau hauv tag nrho, muab kev muaj peev xwm taug kev thiab kev cushioning tag nrho, kev poob siab thiab lub suab nrov txo kev ua haujlwm, cov khoom tseem ceeb yog feem ntau cov roj hmab (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 sib xyaw ua ke thiab polyurethane elastomer.

Cov neeg muag khoom ntawm cov khoom siv raw khoom xws li roj hmab thiab cov hlau xaim feem ntau yog los ntawm Tuam Tshoj thiab cov teb chaws Asia, Europe, Tebchaws Asmeskas thiab lwm thaj chaw muaj kev nplua nuj.
