Roj hmab hose yog ib hom yeeb nkab uas ua los ntawm cov khoom siv roj hmab. Nws yog qhov hloov tau yooj yim thiab ntau yam, thiab feem ntau yog siv rau kev hloov cov kua thiab roj hauv ntau qhov kev lag luam. Cov txheej txheem ntawm cov roj hmab hose muaj ob peb kauj ruam, txhua tus ua lub luag haujlwm tseem ceeb hauv kev ua tau zoo thiab kev ua tau zoo ntawm cov khoom kawg.
Kauj Ruam 1: Sib tov
Thawj kauj ruam hauv kev ua cov roj hmab hose yog kev sib xyaw ntawm cov roj hmab sib xyaw. Qhov no suav nrog kev sib xyaw ntau hom hluavtaws lossis roj hmab ntuj nrog lwm cov ntaub ntawv xws li carbon dub, plasticizers, thiab curing agents. Tom qab ntawd cov sib tov yog kneaded kom txog thaum ib tug uniform sib xws yog tiav.
Kauj Ruam 2: Extrusion
Cov kauj ruam tom ntej yog extrusion, qhov twg cov roj hmab compound raug yuam los ntawm kev tuag los tsim ib lub raj txuas ntxiv. Cov txheej txheem no yog ua tiav siv cov tshuab tshwj xeeb uas siv cov cua sov thiab lub siab rau cov khoom siv thaum nws dhau los ntawm kev tuag. Txoj kab uas hla thiab thickness ntawm cov tubing tuaj yeem hloov kho qhov loj thiab cov duab ntawm qhov tuag.
Kauj Ruam 3: Txhim kho
Qee qhov xwm txheej, yuav tsum muaj kev txhawb nqa ntxiv los ntxiv dag zog rau lub hose. Qhov no tuaj yeem ua tiav los ntawm kev siv cov woven los yog braided hluavtaws fibers, uas yog qhwv ib ncig ntawm lub raj thaum lub sij hawm extrusion txheej txheem.
Kauj Ruam 4: Kho
Tom qab extrusion, cov roj hmab hose yog kho kom nws tsim thiab tau txais nws lub cev kawg nkaus. Qhov no suav nrog muab cov hose tso rau hauv qhov cub lossis autoclave thiab ua rau nws kub siab rau lub sijhawm teem tseg. Cov txheej txheem no ua rau cov roj hmab sib txuas rau kev sib txuas, ua kom muaj zog, ruaj khov thiab ruaj khov ntawm cov molecules.
Kauj Ruam 5: Ua kom tiav
Thaum kawg, cov roj hmab hose tau ua tiav cov txheej txheem xws li txiav, kuaj, thiab daim ntawv lo. Lub hose yog txiav mus rau qhov ntev yuav tsum tau, thiab fittings yog txuas rau txhua qhov kawg. Tom qab ntawd lub hose raug kuaj xyuas kom nws ua tau raws li cov qauv tsim nyog. Thaum lub hose tau dhau qhov kev sim, nws tau sau nrog cov lus qhia tsim nyog thiab xa mus rau cov neeg siv khoom.
Hauv kev xaus, kev tsim cov roj hmab hoses yog cov txheej txheem nyuaj uas muaj ntau cov kauj ruam thiab xav tau cov neeg ua haujlwm txawj thiab cov tshuab siab heev. Cov khoom tsim tau yog ntau yam, ruaj khov, thiab tseem ceeb rau ntau qhov kev lag luam. Kev tsim cov roj hmab hoses yog qhov zoo siab thiab tseem ceeb ntawm kev tsim khoom lag luam, thiab nws txoj kev txhim kho txuas ntxiv thiab kev tsim kho tshiab yuav ua kom nws qhov tseeb thiab kev vam meej rau xyoo tom ntej.
