Cov khoom siv nthuav dav hluav taws yog dab tsi?

Cov khoom siv nthuav dav uas tiv taus hluav tawsyog ib hom khoom siv hauv kev tsim kho uas tsim los nthuav dav thaum raug rau qhov kub siab, tsim ib txheej char insulating uas pab kaw cov qhov sib txawv thiab tiv thaiv kev kis hluav taws, pa luam yeeb, thiab cov pa lom. Cov ntaub ntawv no feem ntau siv rau hauv cov ntawv thov tiv thaiv hluav taws kom txhim kho kev tiv thaiv hluav taws ntawm cov tsev, cov kab ke hluav taws xob, thiab cov qauv kev lag luam.

Hom Khoom Siv Hluav Taws Xob Uas Ua Rau Kom Nthuav Dav:

1. Cov Ua Npuas Ncauj Thiab Cov Tshuaj Sealant Uas Tiv Thaiv Tau Hluav Taws
   • Siv nyob ib puag ncig cov kav dej, cov xov hlau, thiab cov pob qij txha kom nthuav dav thiab kaw cov qhov sib txawv thaum muaj hluav taws.
   • Piv txwv li: Intumescent firestop ua npuas ncauj.
2. Cov Tshuaj Pleev Xim thiab Cov Xim Uas Ua Rau Muaj Teeb Meem
   • Thaum cua sov, nws yuav o tuaj, ua ib txheej tiv thaiv rwb thaiv tsev rau saum hlau, ntoo, lossis lwm yam khoom siv.
   • Piv txwv li: Xim pleev rau cov nqaj hlau uas tiv taus hluav taws.
3. Cov Khoom Siv Sib Koom Tes Uas Tiv Thaiv Hluav Taws
   • Siv rau hauv kev tsim cov pob qij txha kom tso cai rau kev txav mus los thaum tswj hwm kev tiv thaiv hluav taws.
   • Piv txwv li: Cov ntaub plaub mos mos uas muaj cov kab txaij intumescent.
4. Cov Cug Thiab Cov Putty Uas Tiv Thaiv Tau Hluav Taws
   • Nthuav dav kom puv cov kab nrib pleb thiab cov qhov khoob hauv phab ntsa, pem teb, thiab cov ntsaws ruaj ruaj.
   • Piv txwv li: Cov roj hmab silicone uas tiv taus hluav taws.
5. Cov Ntawv Qhia Txog Kev Mob Hlwb Uas Muaj Graphite
   • Siv rau hauv qhov rooj thiab qhov rai kom nthuav dav thiab thaiv hluav taws kom tsis txhob kis mus.

Cov Khoom Tseem Ceeb:

• Qhov Sib Piv Txwv:Thaum cua sov, nws yuav nthuav tau 5–50 npaug ntawm qhov loj qub.
• Kev Tiv Thaiv Hluav Taws:Tiv taus qhov kub ntawm 500 ° C mus txog ntau tshaj 1000 ° C.
• Kev rwb thaiv tsev:Tsim ib txheej charred uas qeeb qeeb hloov pauv cua sov.
• Kev thaiv pa luam yeeb thiab tshuaj lom:Tiv thaiv kom tsis txhob muaj roj xau.

Cov ntawv thov:

• Kev tiv thaiv hluav taws xob cable nkag mus.
• Kaw cov qhov sib txawv ntawm cov phab ntsa thiab cov plag tsev uas muaj hluav taws kub.
• Tiv thaiv cov hlau ua vaj tse los ntawm kev tawg vim cua sov.
• Cov qhov rooj hluav taws, cov kav dej HVAC, thiab cov yeeb nkab nkag mus.

Cov ntaub ntawv no tseem ceeb heev rau cov txheej txheem tiv thaiv hluav taws kub, kom ua raws li cov cai kev nyab xeeb hauv tsev (piv txwv li, ASTM E814, UL 1479). Koj puas xav tau cov lus qhia rau ib daim ntawv thov tshwj xeeb?
