Lub cultivation ntawm roj hmab ntoo yog concentrated nyob rau hauv cov cheeb tsam huab cua, nrog cov teb chaws xws li Thaib teb, Indonesia, thiab Malaysia yog cov neeg tsim khoom loj tshaj plaws.

Cov khoom ntawm cov roj hmab ntuj

Cov roj hmab muaj suab nrov rau nws zoo heev elasticity, lub zog siab tensile lub zog, thiab kev tiv thaiv hnav thiab kua muag. Nws tseem ua pov thawj cov hluav taws xob hluav taws xob zoo hluav taws xob thiab ua haujlwm tau zoo hauv qhov chaw tsawg-qhov chaw ib puag ncig. Txawm li cas los xij, nws muaj kev txwv, xws li tsis kam mus cua sov, lub teeb, thiab nws, uas tuaj yeem ua rau muaj kev cuam tshuam rau lub sijhawm.

Cov Roj Hmab Hluav Taws Xob: Kev Tsim Kho Niaj Hnub

Kev Loj Hlob Ntawm Cov Roj Hmab Hluav Taws Xob

Cov roj hmab hluavtaws tau tsim los ua cov lus teb rau cov kev txwv ntawm cov roj hmab ntuj thiab kev xav tau ntau yam ntxiv. Thawj cov roj hmab hluav taws xob, hu ua Buna, tau tsim nyob rau hauv thaum ntxov xyoo pua 20th. Txij thaum ntawd los, nce qib hauv cov roj hmab ntau yam ntawm cov roj hmab hluav taws xob, suav nrog roj hmab styrene, xws li ethylene-propylene-diene monomer (epdm).

Cov Khoom Siv Hluav Taws Xob ntawm Khoom Siv Roj Hmab

Cov roj hmab hluavtaws muaj ob peb qhov zoo dhau ntawm cov roj hmab ntuj, xws li kev txhim kho tiv thaiv kom sov, tshuaj lom neeg, thiab kev laus. Nws tuaj yeem raug txiav kom ua tau raws li qhov yuav tsum tau ua los ntawm kev hloov kho nws cov tshuaj lom neeg muaj pes tsawg leeg. Piv txwv li, EPDM yog qhov muaj zog tiv thaiv huab cua thiab ozone, ua rau nws zoo tagnrho rau kev siv sab nraum zoov, thaum NBR paub txog nws cov roj ua tau zoo heev.

Kev Tshaj Tawm Kev Tshawb Xyuas: Cov Roj Hmab Hluav Taws Xob

Kev ua tau zoo hauv ntau yam kev siv

Cov roj hmab muaj cov roj hmab tau siv nyob rau hauv cov ntawv thov thiab lub zog tensile, xws li cov log tsheb, conveyor siv tawv, thiab khau. Ntawm qhov tod tes, cov roj hmab hluavtaws yog nyiam nyob hauv ib cheeb tsam uas tsis kam rau huab cua sov, tshuaj lom neeg, lossis kev laus yog qhov tseem ceeb. Piv txwv li, SBR yog feem ntau siv hauv cov log tsheb ntau, thaum cov roj hmab silicone siv rau hauv cov cuab yeej kho mob thiab cov ntsaws ruaj ruaj.

Cuam tshuam ib puag ncig

Kev tsim cov khoom siv roj hmab muaj ib puag ncig ib puag ncig vim muaj kev tawm tsam thiab siv tshuaj lom neeg hauv cov roj hmab. Cov roj hmab hluavtaws hluavtaws, thaum txo qis chaw nyob ntawm cov khoom siv ntuj tsim, muaj kev txhawj xeeb txog cov khoom lag luam roj carbon monissions thiab tsis yog biodegradability. Kev siv zog tau ua los tsim kev xaiv kom muaj kev xaiv hluav taws xob, xws li roj hmab hluavtaws hluavtaws hluav taws xob hluav taws xob.

Tag

Hauv kev xaiv, kev xaiv ntawm cov roj hmab thiab hluavtaws hluavtaws yog nyob ntawm qhov tshwj xeeb ntawm daim ntawv thov. Thaum cov roj hmab muaj cov roj hmab hauv elasticity thiab tensile lub zog, hluavtaws roj hmab muaj cov roj thiab tshuaj lom neeg. Kev nce qib tsis tu ncua hauv cov thev naus laus zis txuas ntxiv mus nthuav tawm cov peev txheej rau ob hom roj hmab, kom lawv cov kev lag luam sib txawv.

Rau cov neeg nyiam tshawb nrhiav hom ntau ntau hom hluavtaws roj hmab thiab lawv cov ntawv thov, mus saib Cov roj hmab hluavtaws rau cov ncauj lus kom ntxaws.
