Cov roj hmab hoses siv rau dab tsi?

Cov kav dej tau paub txog txhua tus; lawv yog cov kav dej rau kev thauj mus los. Nyob rau hauv xyoo tas los no, nrog rau txoj kev loj hlob ntawm lub sij hawm thiab kev txhim kho ntawm kev ua neej nyob, muaj ntau thiab ntau cov ntaub ntawv rau cov kav dej siv nyob rau hauv lub tsev kho kom zoo nkauj, thiab lawv cov durability yog ua kom muaj zog. Cov neeg siv khoom feem ntau xav tsis meej pem thaum yuav lawv. Yog li dab tsi yog cov kav dej roj hmab, thiab lawv siv rau dab tsi? Hauv qab no, peb yuav txheeb xyuas qhov no kom ntxaws, vam tias yuav pab tau koj!

1. Kev sib xyaw ntawm cov kav dej roj hmab: Cov yeeb nkab phab ntsa muaj peb ntu: ib txheej roj hmab sab hauv, txheej hlua khi hlua, thiab txheej txheej roj hmab sab nraud; los yog nws muaj tsib ntu: ib txheej roj hmab sab hauv, txheej hlua khi hlua, txheej txheej roj hmab nruab nrab, txheej hlua khi hlua, thiab txheej txheej roj hmab, feem ntau hu ua "peb rubbers thiab ob txoj hlua."

2. Cov yam ntxwv thiab kev siv: Cov yeeb nkab lub cev yog hloov tau thiab muaj qhov sib luag. Nws yog tsuas yog siv los thauj huab cua, inert gases, thiab lwm yam, thiab yog ib qho khoom siv rau cov cua compressors thiab lwm yam khoom siv. Cov roj hmab hoses muaj cov khoom xws li lub cev tsis muaj zog, UV tsis kam, ozone tsis kam, siab thiab kub tsis kam (-80 rau 300 degrees Celsius), siab pob tshab, muaj zog resilience, ruaj khov compression tsis kam, roj tsis kam, cuam tshuam tsis kam, acid thiab alkali tsis kam, tsis kam tiv taus, nplaim hluav taws xob, hluav taws xob tiv thaiv, thiab hluav taws xob conductivity.

Cov txheej txheem ntau lawm suav nrog kev sib xyaw qhib, extrusion (cov roj hmab sab hauv), braiding, ziab, txheej txheej roj hmab (xws li TPX lossis ntaub txheej), vulcanization, tev, ntsuas siab, thiab ntim. Qhov tseeb, kev tsim cov roj hmab hoses yog qhov nyuaj heev. Lawv feem ntau yog siv los txuas cov cav rau cov lim cua, lub cav rau lub tshuab hluav taws xob, thiab cov tshuab cua txias hauv tsheb. Raws li ib feem ntawm cov khoom noj khoom haus, lawv nyob ze rau lub cav, yog li yuav tsum tau muaj kev kub ntxhov, roj tsis kam, corrosion kuj, aging kuj, thiab kub tsis kam. Cov khoom siv sib txawv nyob ntawm qhov kev siv thev naus laus zis, suav nrog cov tshuab hluav taws xob thiab cov cua txias hoses.
