Cov Khau Uas Tiv Thaiv Tau Kev Txiav: Cov Lus Txhais, Cov Ntawv Siv, Cov Khoom Siv & Cov Lus Qhia Txog Kev Yuav Khoom

Hauv cov xwm txheej ua haujlwm uas muaj kev pheej hmoo siab xws li kev ua haujlwm kho tshuab, kev txiav ntoo hauv vaj, kev tsim kho thiab kev tua hluav taws, kev raug mob ko taw los ntawm cov hniav ntse, cov npoo hlau thiab cov khib nyiab ntawm lub tshuab txiav ntoo yog cov xwm txheej hauv kev lag luam uas tshwm sim ntau tshaj plaws. Cov khau ua haujlwm ib txwm thiab cov khau yooj yim tsuas yog tiv taus kev hnav yooj yim xwb thiab tsis tuaj yeem tiv taus kev txiav thiab khawb hnyav.Cov khau looj uas tiv taus kev txiavyog cov khoom siv tiv thaiv ko taw uas ua haujlwm tau zoo uas tiv thaiv kev raug mob ntawm qhov txiav thiab ua haujlwm ua cov khoom siv kev nyab xeeb tseem ceeb rau cov neeg ua haujlwm hauv qhov chaw muaj kev pheej hmoo siab. Tsab xov xwm no piav qhia txog cov ntsiab cai tiv thaiv, cov ntaub ntawv tseem ceeb, cov xwm txheej siv thiab cov lus qhia yuav cov khau tiv taus qhov txiav kom pab cov neeg ua haujlwm thiab cov neeg yuav khoom xaiv tau sai thiab raug.

Khau looj uas tiv taus kev txiav yog dab tsi thiab lawv cov ntsiab cai tseem ceeb ntawm kev tiv thaiv

Cov khau tiv taus kev txiav yog cov khau tiv thaiv kev nyab xeeb tshaj lij uas tsim tshwj xeeb los tiv taus kev txiav riam, khawb thiab kev cuam tshuam. Txawv ntawm cov khau tiv taus kev cuam tshuam thiab tiv thaiv kev tho, lawv tsom mus rau kev tiv thaiv cov khoom tsis muaj zog xws li lub vamp, sab khau thiab pob luj taws. Tsis yog tsuas yog tiv taus kev txiav los ntawm qhov nyuaj, lawv siv cov qauv fiber tshwj xeeb muaj zog siab los faib lub zog txiav, thaiv cov npoo hniav thiab tiv thaiv cov khoom ntse kom tsis txhob nkag mus. Qhov no txo qhov txiav thiab khawb ntawm ko taw, muab kev nyab xeeb rau txhua qhov chaw rau vamp, sab khau, pob luj taws thiab lwm qhov chaw tsis muaj zog.

Cov Khoom Siv Tseem Ceeb ntawm Khau Uas Tiv Thaiv Kev Txiav: Vim Li Cas Lawv Ua Tau Zoo Dua Khau Ib Txwm

Cov khau tiv taus kev txiav tshaj lij tshem tawm cov tawv thiab cov ntaub PVC ib txwm muaj, thiab siv cov ntaub tiv thaiv tshwj xeeb muaj zog - tus qauv xaiv cov khoom siv tseem ceeb rau Patcus cov khau tiv taus kev txiav. Muaj peb cov ntaub ntawv zoo tshaj plaws:

Txheej Txheem Aramid Fiber Composite

Ua ib yam khoom siv tiv thaiv zoo, cov fiber aramid yog cov khoom siv zoo ib yam li cov tsho tiv thaiv mos txwv. Nws mos thiab yoog tau kom haum rau koj txhais taw yam tsis tas txhuam koj txhais taw. Nws muaj lub zog siab, modulus siab thiab elongation qis, nws ua rau muaj kev tiv thaiv txiav ntau dua thiab tiv thaiv cov hniav nkag thaum ntsib cov cuab yeej ntse. Cov txheej fiber aramid feem ntau yog muab tso rau hauv lub vamp ua ib lub qauv sandwich. Lub teeb yuag, ua pa tau, tiv taus corrosion thiab tiv taus kev laus, nws tsis muaj cov khoom siv hlau thiab tsis ua rau lub tswb ceeb toom ntawm lub tshuab ntes hlau, ua rau nws zoo tagnrho rau kev ua haujlwm siab thiab muaj kev pheej hmoo siab.

Cov Roj Hmab Lag Luam Uas Muaj Thickened & Cov Npuag Muaj Zog Siab Sandwich

Cov khoom siv no ua ke nrog tus nqi tsim nyog, muaj ib txheej roj hmab tuab uas tiv taus kev hnav thiab khawb thiab ib txheej ntaub sab hauv uas tiv taus kev txiav. Nws muaj kev ua haujlwm tsis muaj dej, tiv taus kev hnav thiab tiv taus kev txiav, tsim nyog rau cov xwm txheej txiav nruab nrab thiab qis xws li kev tsim kho vaj tse, kev ua teb thiab kev khaws cia khoom, nrog rau qhov chaw ua haujlwm noo thiab nquag nrog kev siv tau zoo thiab ruaj khov.

Txheej Txheem Polyethylene Composite Ua Haujlwm Zoo

Ua los ntawm cov polyethylene fiber ntau molecular sib xyaw nrog cov iav fiber, cov khoom no yog ultra-light thiab yooj ywm heev nrog kev ruaj khov thiab zoo heevkev ua haujlwm tiv taus kev txiav. Kev sib npaug ntawm kev tiv thaiv thiab kev hnav xis nyob, nws zoo meej rau kev ua haujlwm sab nraum zoov txhua hnub thiab chaw nres tsheb uas xav tau khau sib dua.

Cov Xwm Txheej Tseem Ceeb ntawm Cov Khau Uas Tiv Thaiv Tau Kev Txiav

Cov khau tiv taus kev txiav yog qhov tshwj xeeb rau qhov xwm txheej thiab yuav tsum muaj rau cov haujlwm muaj kev pheej hmoo siab hauv qab no kom tshem tawm cov kev phom sij kev nyab xeeb:

Kev Ua Vaj thiab Kev Txiav Ntoo: Tiv taus kev txiav los ntawm cov chainsaws, cov ceg ntse thiab cov cuab yeej txiav. Kev ua haujlwm ntawm chainsaw xav tau cov khau tiv thaiv chainsaw uas tau ntawv pov thawj - Chav Kawm 1 tiv taus qhov ceev ntawm saw hlau ntawm 20 m/s, thaum Chav Kawm 2 tiv taus 24 m/s, tsim kom muaj kev nyab xeeb tsis sib haum xeeb.

Cov Chaw Ua Haujlwm Kho Tshuab thiab Kho Vaj Khoom SivTiv thaiv kom tsis txhob khawb thiab txiav los ntawm cov hlau ntse, cov khoom ua haujlwm thiab cov hlau pov tseg.

Kev Tsim Kho & Kev Rhuav TshemTiv thaiv ko taw ntawm kev raug mob los ntawm cov iav tawg, cov hlau tawg thiab cov khoom siv hlau ntse.

Kev Tua Hluav Taws thiab Kev Cawm Neeg Thaum Muaj Xwm Ceev: Hloov kho rau qhov chaw cawm neeg nyuaj thiab tiv taus kev pheej hmoo ntawm kev txiav los ntawm cov khoom puas tsuaj thiab cov hlau tawg. Cov khau tiv thaiv kev tua hluav taws feem ntau ua tau raws li ntau tus qauv kev tiv thaiv suav nrog kev tiv taus kev cuam tshuam, tiv thaiv kev tho, tiv taus hluav taws xob thiab tiv taus kev txiav, thiab qee qhov ua raws li NFPA 1971 tus qauv tiv thaiv hluav taws.

Kev Khaws Khoom Thiab Kev Siv Cov Khib Nyhiab Rov QabTsis txhob khawb ko taw thaum lub sijhawm tuav thiab cais cov pob khoom ntse thiab cov khib nyiab hlau.

Cov Qauv Tseem Ceeb rau Kev Yuav Khoom Rau Khau Uas Tiv Thaiv Tau Kev Txiav

Muaj ntau tus neeg yuav khoom tsis nkag siab txog kev tiv thaiv kev hnav thiab kev tiv thaiv kev txiav. Cov khau tiv thaiv kev hnav ib txwm tsuas yog tiv taus kev sib txhuam thiab tsis tuaj yeem tiv thaiv kev txiav ntawm cov hniav ntse. Kawm peb lub ntsiab lus tseem ceeb kom xaiv cov khau tiv thaiv kev txiav uas tsim nyog:

Xaiv Cov Khoom Siv Uas Tiv Thaiv Kev Txiav Thiab Cov Qauv Uas Tau Ntawv Pov Thawj

Xaiv cov khau looj plab hlaub uas muaj cov txheej aramid uas tiv taus kev txiav thiab cov ntaub uas tiv taus kev txiav ntau, thiab zam cov khoom tsis zoo uas hais tias tawv lossis roj hmab tuab tuab ua rau tawv tawv tsis kam txiav. Qhov tseem ceeb tshaj plaws, xyuas kom meej cov qauv ntawv pov thawj: cov khau looj plab hlaub uas tiv taus kev txiav yuav tsum ua raws li EN 388 tus qauv tiv taus kev txiav, EN ISO 20345 tus qauv khau kev nyab xeeb lossis ASTM F2413 tus qauv khau tiv thaiv. Rau cov xwm txheej tua hluav taws hauv tsev, tus qauv GA 6-2004 kuj siv tau. Cov khoom lag luam raug cai cim cov qib tiv thaiv ntxaws ntxaws ntawm cov ntawv cim lossis phau ntawv qhia kom paub tseeb.

Kev Tiv Thaiv Tag Nrho & Kev Hnav Xis Nyob

Cov khau ua haujlwm zoo uas tiv taus kev txiav tau txais kev tsim qauv npog tag nrho yam tsis muaj qhov tsis pom ntawm lub vamp, sab khau thiab pob luj taws. Cov ntaub ntawv zoo tshaj plaws thiab cov duab khau tshem tawm cov qhov tsis zoo ntawm cov khau tiv thaiv ib txwm muaj, txhaws thiab nkees, ua kom muaj kev ywj pheej thiab cua nkag tau rau kev ua haujlwm ntev teev hauv qhov chaw.

Sib phim qib kev tiv thaiv nrog cov xwm txheej ua haujlwm tiag tiag: xaiv cov khau looj roj hmab-ntaub sib xyaw (Qib A1-A3) rau kev ua haujlwm txhua hnub me me; xaiv cov khau looj aramid fiber qib siab uas tiv taus kev txiav (saum toj no Qib A4) rau cov xwm txheej siab thiab muaj kev pheej hmoo siab. Cov qib tiv taus kev txiav thoob ntiaj teb ntawm kev lag luam yog txij li A1 txog A9 - qib siab dua, kev tiv thaiv muaj zog dua. Kev ua haujlwm muaj kev pheej hmoo siab xws li kev ntaus ntawv thiab kev txiav ntoo yuav tsum muaj tsawg kawg yog Qib A4 tiv thaiv kom tsis txhob muaj kev tiv thaiv tsis txaus lossis kev ua haujlwm tsis zoo.

Yuav tsum paub qhov txawv ntawm kev txiav thiab kev tiv thaiv kev tho. Kev tiv thaiv kev tho feem ntau tiv thaiv lub hauv paus ntawm cov khoom ntse, thaum kev tiv thaiv kev txiav tiv thaiv cov vamp thiab sab khau los ntawm kev txiav hniav kab rov tav. Ob lub luag haujlwm tsom mus rau ntau qhov sib txawv thiab cov ntsiab cai thiab tsis tuaj yeem hloov ib leeg. Cov xwm txheej muaj kev pheej hmoo siab xav tau ob qho kev ua tau zoo kom tsis txhob raug mob hauv kev lag luam.
