Nrog rau kev nce qib ntawm kev siv cov khau hauv tsev thiab kev hloov pauv tas mus li hauv ntiaj teb cov ntaub ntawv khau, ntau yam kev nyab xeeb khau tau maj mam dhau los ua ntau yam thiab muaj ntau haiv neeg.
Cov khau kev nyab xeeb tau muab faib ua cov khau kev nyab xeeb thiab cov khau tiv thaiv, uas yog hais txog cov khau khiab uas tiv thaiv ob txhais taw thiab cov menyuam mos kom tsis txhob raug kev raug mob hauv qhov chaw ua haujlwm sib txawv.
Cov khau tiv thaiv kev nyab xeeb yog cov khoom siv high-tech, cov khoom muaj nqis ntxiv rau khau. Kev tsim cov khau tiv thaiv muaj kev xav tau siab rau cov khoom siv raw, cov khoom siv pabcuam, cov khoom siv tshuaj thiab cov khoom siv ntau lawm.
Cov qauv tsim thiab cov kev cai ntawm kev nyab xeeb khau hauv tsev yog maj mam pib ua raws li cov teb chaws txawv teb chaws. Cov qauv kev nyab xeeb hauv Suav teb yog tsim nrog siv rau cov qauv European. Tus qauv tam sim no rau Suav khau kev nyab xeeb yog GB21148-2007.
Tawv kev nyab xeeb khau GB4014-83; roj hmab ntsej muag anti-mite kev nyab xeeb khau GB7054-86.
Cov txheej txheem European yog tsim los ntawm CEN / TC61 Technical Committee ntawm "Kev Tiv Thaiv ntawm Ko Taw thiab Ob Ceg" thiab Lub Tsev Haujlwm Saib Xyuas Haujlwm yog tus thawj coj los ntawm BSI. European tus qauv EN345 "Kev nyab xeeb tshwj xeeb, tiv thaiv thiab ua haujlwm khau". Tus qauv muaj kev nyab xeeb
Cov qauv thiab kev ua tau zoo ntawm cov qauv khau tsim, tag nrho cov khau, sab hauv thiab sab nrauv, sab saud yog teev.
Kev tswj dej nyab kev nyab xeeb khau
Sab hauv hauv ob sab phlu ntawm kev tiv thaiv ntiv taw kev nyab xeeb khau yog lub hau ntiv taw steel, uas muaj kev tiv thaiv zoo li qub thiab cuam tshuam tsis kam, stab-pov thawj thiab tiv thaiv mite. Nws yog tsim rau kev lag luam hnyav xws li mining thiab kev tsim kho, thiab tiv thaiv cov ntiv taw.
Puncture-proof nkawm khau
Cov khau tiv thaiv kev nyab xeeb tiv thaiv cov khau looj plab los ntawm cov pob txha ntse thiab tuaj yeem tiv thaiv kev nkag mus ntawm 1100N. Lawv haum rau kev tiv thaiv hluav taws, hav zoov, tshuab thiab lwm yam lag luam.
Anti-static khau looj plab hlaub
Nws yog tsim raws li tus qauv GB4385-1995 thiab tsim nyog rau roj av thiab aviation kom tsis txhob muaj hluav taws kub thiab tawg tshwm sim los ntawm hluav taws xob zoo li qub.
Roj resistant haumxeeb khau khau
According to the oil resistance test standard, the volume increase is ≥12%. If the volume is reduced, the reduction amount is ≥ 0.5% of the original volume or the hardness is increased by >10, uas yog tsim rau roj av thiab lwm yam kev lag luam.
Acid thiab alkali resistant khau kev nyab xeeb
Haum rau roj av, tshuaj, thiab lwm yam.
Cov kev ceev faj:
1. Acid-resistant tawv khau yog haum rau acid thiab alkali qhov chaw uas tsis muaj concentration;
2. Tsis txhob muaj qhov kub thiab txias, kev puas tsuaj rau sab sauv thiab ib leeg;
3. Tom qab ntxuav, yaug cov kua qaub thiab alkali ntawm cov khau nrog dej thiab tsis txhob raug tshav ntuj ncaj qha lossis ziab thaum ziab.
Kev nyab xeeb khau muaj qhov ua haujlwm zoo ua haujlwm, tiv thaiv zoo li qub, hnav-tiv taus, tiv thaiv plam thiab lwm yam haujlwm, nyiam hnav, thiab tsis cuam tshuam rau kev ua haujlwm niaj hnub.
Kev tu
Kev nyab xeeb khau yuav tsum tau siv thiab tswj kom zoo. Kev ceev faj yog raws li nram no:
1. Ntxuav nkawm khau tsis tu ncua, tsis txhob siv cov kuab tshuaj ua cov tshuaj detergents.
2. Tsis tu ncua ntxuav cov pob qij txha kom tsis txhob tsub zuj zuj ntawm cov av, uas yuav ua rau cov conductivity los yog anti-static nyhuv yuav cuam tshuam los ntawm av thiab ua rau lub neej txaus ntshai.
3. Tsis txhob arbitrarily hloov kev tsim kho cov khau kev nyab xeeb. Kev hloov pauv hloov pauv tuaj yeem cuam tshuam qhov ntsuas kev nyab xeeb ntawm nkawm khau kev nyab xeeb.
4. Cov khau ruaj ntseg yuav tsum muab cia rau hauv qhov chaw txias, qhuav thiab qhov cua zoo.
Cov neeg feem coob xav tias khau tiv thaiv yog khau kev nyab xeeb. Raws li Tuam Tshoj tus qauv tam sim no, khau kev nyab xeeb thiab khau tiv thaiv yog ob qho qauv sib txawv. Lub teb chaws tus qauv GB21148-2007 rau khau kev nyab xeeb thiab lub teb chaws tus qauv GB21147-2007 rau khau tiv thaiv.
Nkawm khau kev nyab xeeb yog cov qauv siab, cov qauv kev nyab xeeb siab.
