Yuav ua li cas xaiv thiab siv cov txheej txheem tiv thaiv hluav taws rau cov qauv hlau

Rau cov tsev ua los ntawm hlau, yuav tsum muaj kev tiv thaiv hluav taws. Txawm hais tias hlau nws tus kheej tsis kub hnyiab, nws lub zog yuav txo qis sai sai thaum kub siab, ua rau cov qauv puas tsuaj. Yuav tsum muaj kev tiv thaiv hluav taws rau cov qauv hlau, thiab kev siv cov txheej tiv thaiv hluav taws yog ib qho ntawm cov txheej txheem tseem ceeb thiab tseem ceeb tshaj plaws los ua tiav qhov no. Niaj hnub no, peb yuav qhia txog yuav ua li cas xaiv thiab siv cov txheej tiv thaiv hluav taws rau cov qauv hlau.

Cov txheej txheem tiv thaiv hluav taws rau cov qauv hlau muaj ob hom: intumescent thiab non-intumescent. Hauv qab no yog cov lus qhia luv luv txog lawv qhov sib txawv:

Tam sim no peb paub lawv cov ntaub ntawv thiab qhov sib txawv, cia kuv qhia koj yuav ua li cas xaiv cov txheej tiv thaiv hluav taws uas haum rau koj: Rau cov chaw sab hauv tsev uas muaj kev xav tau zoo nkauj, xws li cov khw loj, cov chaw ua haujlwm, cov chaw ua yeeb yam, thiab cov chaw tos tshav dav hlau, cov hlau beams thiab kem raug nthuav tawm, thiab tsis yog tsuas yog xav tau qhov zoo nkauj xwb tab sis kuj ua haujlwm tiv thaiv hluav taws zoo, yog tias xav tau lub sijhawm tiv thaiv hluav taws tsawg dua 2 teev (lossis 2.5 teev), xav kom siv cov txheej tiv thaiv hluav taws intumescent. Rau cov qauv hlau sib dua thiab cov qauv thav duab chaw, kuj xav kom siv cov txheej tiv thaiv hluav taws intumescent, vim tias cov qauv no rhiab rau kev thauj khoom, thiab qhov sib dua ntawm cov txheej tiv thaiv intumescent yog qhov zoo heev.

Rau cov qauv hlau siab thiab cov khoom siv thauj khoom, qhov twg kev nyab xeeb ntawm cov qauv tseem ceeb dua li cov txiaj ntsig zoo nkauj, thiab rau cov haujlwm hnyav lossis petrochemical xws li cov nroj tsuag kev lag luam thiab cov chaw petrochemical uas muaj kev tiv thaiv hluav taws kub heev, xav kom xaiv cov txheej tiv thaiv hluav taws uas tsis kub hnyiab; rau lub sijhawm tiv thaiv hluav taws ≥3 teev; thiab rau cov qauv zais thiab cov qauv hlau uas tsis tshua muaj kev saib xyuas cov yam ntxwv zoo nkauj, cov txheej tiv thaiv hluav taws uas tsis kub hnyiab kuj yuav tsum tau muab qhov tseem ceeb.

Txawm hais tias tus nqi ntawm cov txheej tiv thaiv hluav taws kub intumescent kim dua, lawv xav tau tsawg dua thiab yooj yim siv. Tus nqi ntawm cov txheej uas tsis yog intumescent pheej yig dua, tab sis lawv cov txheej tuab dua, xav tau ntau dua rau ib cheeb tsam, yog li tus nqi ntawm cov khoom siv tsis tas yuav qis dua. (Qhov tuab ntawm cov txheej uas tsis yog intumescent yuav tsum tsis pub tsawg dua 15 hli, txwv tsis pub, nws nyuaj rau lav qhov zoo ntawm kev siv thiab cov nyhuv tiv thaiv hluav taws.)

Hauv ntej, nws yog qhov sib pauv ntawm "kev zoo nkauj thiab lub teeb yuag" thiab "kev tiv taus hluav taws thiab kev ruaj khov." Yog tias qhov project yog sab hauv tsev thiab kev zoo nkauj yog qhov tseem ceeb, cov txheej txheej intumescent yog thawj qhov kev xaiv; txawm li cas los xij, yog tias nws cuam tshuam nrog cov khoom tseem ceeb ntawm cov tsev lag luam hnyav lossis cov qauv hlau siab, cov txheej txheej tsis-intumescent, nrog lawv qhov ruaj khov thiab kev tiv taus hluav taws siab, yog lub hauv paus txhim khu kev qha dua.

Tom qab xaiv cov txheej txheem uas tiv taus hluav taws tau zoo lawm, kev tsim kho kom raug yog qhov tseem ceeb rau kev ua tiav cov txiaj ntsig zoo tshaj plaws. Nov yog qee cov lus qhia zoo rau kev tsim kho:

1) Kev Kho Qhov Chaw: Xyuas kom tseeb tias qhov chaw hlau huv, qhuav, thiab tsis muaj xeb lossis cov khoom qias neeg. Kev siv ib txheej ntawm cov tshuaj tiv thaiv xeb tuaj yeem ua rau muaj kev sib txuas zoo dua thiab txhim kho kev ua haujlwm tag nrho. Qhov no yog qhov tseem ceeb rau kev ua kom muaj kev sib txuas ruaj khov ntawm cov txheej tiv thaiv hluav taws thiab cov qauv hlau thiab yuav tsum tsis txhob raug tshem tawm.

2) Qhov tuab yog qhov qhia tseem ceeb: Tus qauv hauv tebchaws GB 14907-2018, "Cov Txheej Txheem Tiv Thaiv Hluav Taws Xob rau Cov Qauv Hlau", qhia meej meej tias qhov tuab ntawm cov txheej txheem tiv thaiv hluav taws kub tsis pub tsawg dua 1.5 hli, thiab qhov tuab ntawm cov txheej txheem tiv thaiv hluav taws kub tsis pub tsawg dua 15 hli. Qhov no yog qhov yuav tsum tau ua kom ntseeg tau tias kev tsim kho zoo thiab cov nyhuv tiv thaiv hluav taws kub. Tib lub sijhawm, cov lus qhia ntawm cov chaw tsim khoom txog qhov tuab ntawm cov txheej txheem, lub sijhawm ziab, thiab cov xwm txheej ib puag ncig yuav tsum tau ua raws. Qhov no yuav ua kom ntseeg tau tias cov txheej txheem ua tiav nws qhov kev ua tau zoo.

3) Kev saib xyuas tsis tu ncua: Tshawb xyuas qhov chaw ntawm cov xim pleev kom paub seb puas muaj cov cim qhia tias puas los yog puas tsuaj. Kho cov teeb meem sai sai kom tswj tau qhov ntsuas tiv taus hluav taws.

Thaum siv cov txheej tiv thaiv hluav taws intumescent, nws yog ib qho tseem ceeb kom paub tseeb tias sib xws thiab sib xws nrog cov txheej tiv thaiv xeb thiab cov txheej sab saud; txwv tsis pub, qhov cuam tshuam intumescent yuav raug cuam tshuam, uas ua rau txheej tev tawm. Cov txheej txheem siv ib txwm yog: primer tiv thaiv xeb → txheej nruab nrab tiv thaiv xeb → txheej tiv thaiv hluav taws intumescent → txheej sab saud tiv thaiv xeb. Yog xav paub ntxiv txog cov txheej tiv thaiv hluav taws, thov hu rau Forest Paint, tus thawj coj hauv kev lag luam.
