Kev xaiv cov khoom siv raw: xaiv cov khoom siv kho mob qib roj hmab, xws li roj hmab ntuj,nitrile roj hmab, silicone roj hmab, thiab lwm yam.
Cov qauv tsim: Raws li cov khoom yuav tsum tau ua, tsim cov qauv roj hmab tsim nyog, thiab xyuas kom meej tias nws tsis muaj tshuaj lom thiab tsis ua xua.
Pwm ua: Raws li cov khoom kos duab, ua cov pwm zoo kom paub meej qhov tseeb thiab qhov zoo ntawm cov khoom.
Cov txheej txheem ntau lawm: Kev tsim khoom yog ua raws li txheej txheem txheej txheem ntws, suav nrog roj hmab sib xyaw, calendering, txiav, molding, thiab lwm yam.
Kev Tswjhwm Zoo: Los ntawm kev soj ntsuam nruj thiab cov txheej txheem, xyuas kom meej tias cov khoom ua tau raws li qhov yuav tsum tau ua ntawm qib kev kho mob.
Thaum kho cov khoom siv kho mob roj hmab, cov neeg siv khoom yuav tsum xav txog tag nrho cov hauv qab no:
Biocompatibility ntawm cov ntaub ntawv: xaiv cov khoom siv roj hmab nrog kev sib raug zoo nrog tib neeg lub cev, xws li roj hmab silicone, EPDM roj hmab, thiab lwm yam.
Corrosion resistance: Xav txog cov tshuaj uas cov khoom yuav tuaj yeem tiv nrog thaum siv, xaiv cov khoom siv roj hmab uas muaj zog corrosion kuj.
Kev tiv thaiv kev laus: Xav txog cov xwm txheej ib puag ncig thaum siv cov khoom, xws li ultraviolet rays, kub, thiab lwm yam, thiab xaiv cov khoom siv roj hmab nrog cov khoom zoo los tiv thaiv kev laus.
Kev Nyab Xeeb: Ua raws li cov qauv kev nyab xeeb uas cuam tshuam los xyuas kom meej tias cov khoom yuav tsis tsim cov tshuaj phem lossis ua rau muaj kev tsis haum tshuaj thaum siv.
Cost-effectiveness: Nyob ntawm qhov chaw ua tau raws li qhov yuav tsum tau ua, tswj tus nqi tsim nyog thiab txhim kho cov khoom sib tw.
4. Kev lag luam xav tau thiab kev cia siab
Nrog kev txhim kho txuas ntxiv ntawm kev kho mob thev naus laus zis, kev lag luam xav tau rau cov khoom siv kho mob roj hmab yuav txuas ntxiv mus. Hauv ob peb xyoos tom ntej no, kev tshawb fawb thiab kev tsim kho thiab kev siv cov khoom siv kho mob tshiab yuav dhau los ua qhov tseem ceeb ntawm kev lag luam, xws li cov khoom siv kho mob hnav, cov khoom siv kho mob ntse thiab lwm yam. Nyob rau tib lub sijhawm, raws li lub ntiaj teb cov pej xeem kev laus zuj zus zuj zus, qhov kev thov rau cov khoom siv kho mob roj hmab siv los ntawm cov neeg laus yuav nce ntxiv.
