Ntawm ntau yam ntawm cov neeg tua hluav taws loj loj, ib qho ntawm cov pheej yig tshaj plaws thiab tib lub sijhawm, cov ntaub ntawv tua hluav taws zoo heev (xws li lev), ua los ntawm cov ntaub ntom ntom uas tsis yog nplaim taws.

Lub hom phiaj ntawm daim ntaub thaiv hluav taws

Lub luag haujlwm tseem ceeb ntawm cov ntaub tua hluav taws (cov ntaub mats) yog txhawm rau thaiv hluav taws ntawm thawj theem. Los ntawm pov ib daim ntaub hla lub nplaim taws, koj tuaj yeem nres qhov kev nkag ntawm cov pa oxygen, txo cov nplaim taws thiab yog li tsim kom muaj qhov thaiv hluav taws. Ob peb qhov hluav taws kub tuaj yeem muab tua nrog ib daim ntaub uas tsis yog nplaim taws, tsis zoo li cov hluav taws tua hluav taws, uas yuav tsum tau them rov qab tom qab siv. Lub canvas yog siv kom txog thaum nws ua tsis tau. Lawv feem ntau tiv thaiv cov qauv thiab cov khoom siv (cov tank nrog cov kua dej uas muaj hluav taws kub, lub tog raj kheej roj) los ntawm hluav taws xob hluav taws xob thiab hluav taws xob thaum ua haujlwm nrog hluav taws.

Properties

Cov canvas yog ib daim duab plaub ntawm cov ntaub ruaj khov ua los ntawm cov khoom siv hluav taws xob tsis muaj hluav taws kub (fiberglass). Lub cheeb tsam ntawm lub canvas yog peb square meters. Nws qhov hnyav tsis tshaj ib kilogram. Qhov xav tau muab tso rau hauv tshwj xeebnpog uas tso cai rau koj tshem tawm cov canvas sai txaus (hauv tsib vib nas this). Nyob ntawm tus qauv (PP-300, 600, 1000, 1200), cov ntaub yuav tsum tiv taus qhov kub thiab txias los ntawm rho tawm plaub caug rau ntxiv rau ib txhiab degrees. Thaum kub ntawm -40 txog +50 degrees Celsius, nws lub neej txee yog ntau tshaj peb xyoos. Tag nrho cov kev pabcuam yuav tsum tsis pub tshaj 7 xyoo.

Txhua yam ntawm cov ntaub ntawv los ntawm cov ntaub lev tau ua zoo kawg nkaus tiv thaiv kev ua haujlwm ntawm cov rwb thaiv tsev kub.

Thaum yav dhau los, thaum tsis muaj qhov niaj hnub no rau kev tua hluav taws, xav tias yog tsim los ntawm cov ntxhuav los yog yaj ntaub plaub, thiab ua kom nws tiv taus hluav taws, nws yog impregnated nrog av nplaum sib tov.

Hnub no, ntxiv rau qhov hluav taws kub-tawm-hom kev xav lev, cov ntaub ua los ntawm ntau hom silica fabrics yog siv, uas ua tau zoo kawg nkaus ua haujlwm ntawm cov rwb thaiv tsev kub. Cov ntaub ntawv xws li fiberglass, hluav taws kub-resistant tarpaulins, los yog asbestos (roob flax). Lawv tau coated nrog cov tshuaj tshwj xeeb uas muaj polysaccharides, cov pos hniav arabic, guar gum, agar thiab lwm yam tshuaj.

Tawm kom tsis txhob kis hluav taws thiab cawm tib neeg txoj sia ua tsaug rau nws cov yam ntxwv zoo heev refractory.

Qhov chaw

Txhawm rau kom pom cov ntaub ntawv yooj yim, tshem tawm sai thiab siv, nws yuav tsum nyob hauv qhov chaw pom thiab siv tau. Cov ntaub pua plag yuav tsum nyob ntawm cov ntaub thaiv hluav taws (hom ShchP-SKh, ShchP-V, ShchP-E), vim nws yog ib feem ntawm qhov hluav taws kub.cuab yeej. Tsis tas li ntawd, canvases yog nruab nrog mobile hluav taws sawv thiab cov ntaub thaiv npog. Feem ntau, cov pam hluav taws muaj nyob rau hauv tsheb, tsheb nqa cov kua dej thiab cov pa roj, hauv cov chaw kuaj tshuaj, hauv cov chaw ua haujlwm thiab cov chaw ua haujlwm.

Cov Cai Siv

Zoo li lwm yam khoom siv hluav taws kub, cov ntaub so ntswg tsuas siv tau rau nws lub hom phiaj. Lub canvas yuav tsum tau muab tshem tawm los ntawm lub hnab-npog, ncaj thiab coj mus rau hauv xws li ib txoj kev los ntawm cov leeg thiaj li hais tias nws tau muab tso rau nruab nrab ntawm tus neeg uas nqa tawm lub extinguishing thiab hluav taws. Ntxiv mus kom deb ntawm koj yuav tsum npog lub hearth. Lub hauv paus ntawm ignition yuav tsum tau mus txog tsuas yog los ntawm windward sab. Thaum tsis muaj peev xwm npog tau, ib tug yuav tsum sim coj cov nplaim taws nrog ib daim lev.

Txhua zaus cov ntaub pua tsev raug tshuaj xyuas qhov kev puas tsuaj ntawm cov kua muag lossis qhov chaw hlawv. Cov ntaub puas tuaj yeem rov siv dua. Tsis tas li ntawd, tom qab tua hluav taws kub hnyiab tau thiab cov khoom oily, nws yog txwv tsis pub rov siv cov kev xav, vim tias cov tshuaj tuaj yeem nqus tau rau hauv cov ntaub.

Scope of application

Raws li txoj cai tam sim no, daim pam hluav taws yog siv los tua hluav taws ntawm ntau chav kawm. Namely:

• chav A - cov khoom siv hluav taws kub uas muaj cov khoom siv hluav taws xob hauv lub xeev;
• class B - cov ntaub ntawv uas muaj cov khoom siv hluav taws xob hlawv hauv lub xeev ua kua;
• class C thiab E - cov khoom siv hluav taws xob kub kub hauv qab siabvoltage.

txiaj ntsig

Fireproof xav tau ntau yam zoo. Nws cov txiaj ntsig tseem ceeb suav nrog:

• Vim tsis muaj cov tshuaj carcinogenic, tsis muaj kev cuam tshuam rau kev noj qab haus huv thaum siv.
• Thaum raug kub hnyiab, qhov xav tau yog tiv taus shrinkage, tsis ua hluav taws xob.
• Kev tiv thaiv zoo rau qhov chaw nruj heev (corrosion, lwj, kab mob, dej hiav txwv ntsev), hnav-tiv taus. Ib zaug yuav, ib daim duab yuav kav ntev xyoo.
• Kev ua haujlwm siab, txawm tias tus nqi me me.

Flaws

Li ntawd, daim pam hluav taws tsis muaj qhov tsis zoo. Qhov tsuas yog qhov koj yuav tsum tau ua tib zoo saib yog qhov tseeb ntawm txoj kev siv.

Cov haujlwm ua haujlwm

Nws yog txwv tsis pub nyob rau hauv qhov chaw uas cov ntaub pua tsev khaws cia, siv hluav taws qhib, tshuaj lom neeg, roj thiab roj nplua nyeem. Thaum lub xeev txwv ntawm lub canvas los (cov leeg raug puas tsuaj thiab muaj cov kua muag pom), nws kuj raug txwv tsis pub siv.
