Qhov tseem ceeb npaum li cas yog txhaj blasting rau qhov zoo ntawm cov yeeb nkab insulated?

Aug 20, 2026 Tso lus

Precast ncaj qha- faus insulated kav muaj peb txheej: ib tug ua hauj lwm steel yeeb nkab, ib tug polyurethane rwb thaiv tsev txheej, thiab ib tug txheej tiv thaiv yeeb nkab. Lub zog ntawm daim ntawv cog lus ntawm peb txheej no ncaj qha txiav txim siab cov yeeb nkab txoj sia. Kev txhaj tshuaj blasting yog thawj kauj ruam hauv kev ua kom muaj kev sib raug zoo ntawm cov yeeb nkab steel ua haujlwm thiab txheej rwb thaiv tsev. Kev txhaj tshuaj blasting yog siv high- tua ceev kom "sib tsoo" ntawm cov yeeb nkab steel. Nyob rau hauv lub tshuab txhaj tshuaj blasting, steel txhaj yog propelled ntawm kev kub ceev mus rau hauv cov yeeb nkab nto, siv cov kev cuam tshuam thiab kev sib txhuam kom tshem tawm cov kab mob xws li xeb, nplai, dov steel flakes, roj, plua plav, thiab ya raws. Ib txhij, qhov siab - txhaj tshuaj nrawm tsim cov micro- qhov sib txawv ntawm cov yeeb nkab nto, hu ua "cov qauv thauj tog rau nkoj." Ib qho chaw huv si thiab ntxhib ntxhib ntxhib ua rau lub ntsej muag polyurethane ua kom nruj dua thaum foaming.

 

Muaj cov qauv kev lag luam meej rau kev kho saum npoo ntawm cov kav dej steel. Cov qib txhaj tshuaj tiv thaiv xeb yuav tsum ncav cuag Sa2.5, thiab cov qauv thauj tog rau nkoj qhov tob yuav tsum ncav cuag 50 txog 90 micrometers. Tsis txaus thauj tog rau nkoj qauv qhov tob yuav ua rau tsis zoo npuas adhesion; Qhov tob ntau dhau yuav ua rau cov yeeb nkab phab ntsa tsis muaj zog, yog li nws yuav tsum tau tswj hwm hauv qhov tsim nyog. Tom qab txhaj tshuaj blasting, cov txheej txheem tom ntej foaming yuav tsum tau ua nyob rau hauv 4 teev los tiv thaiv cov yeeb nkab steel kho kom tsis txhob ntub thiab xeb dua.

Hla txoj kev txhaj tshuaj blasting yuav cuam tshuam ncaj qha rau lub sijhawm ntev - lub sijhawm ua haujlwm ntawm cov kav dej. Kev ua tsis tiav ntawm kev tua blast cov yeeb nkab ua haujlwm yog ib qho ntawm cov laj thawj tseem ceeb rau txheej txheej rwb thaiv tsev tev tawm vim cua sov. Thaum cov txheej txheej rwb thaiv tsev thiab cov yeeb nkab steel sib cais, cov raj xa dej poob nws cov qauv kev sib xyaw, cov av nkos quab yuam tsis tuaj yeem hloov mus rau cov yeeb nkab steel, thiab cov raj xa dej tsis txaus thaum lub sij hawm thermal expansion thiab contraction, yooj yim ua rau lub zos deformation los yog ua rau tag nrho stability ntawm cov kav dej. Dab tsi tshwm sim yog qhov teeb meem adhesion thaum kawg cuam tshuam rau kev nyab xeeb ntawm tag nrho cov kav dej.

 

Ntau cov yeeb nkab insulated manufacturers tau nruab nrog lub tshuab tua hluav taws xob tua blasting cov kab ntau lawm los ua cov yeeb nkab steel ntawm cov kab sib txawv thiab siv cov cuab yeej tshaj lij los ntsuas seb cov qauv thauj tog rau nkoj qhov tob raws li cov qauv. Txawm li cas los xij, qee cov tuam txhab me me yuav tsis muaj cov cuab yeej tua blasting txhua, lossis txawm tias lawv ua, lawv tsuas yog ua cov txheej txheem yam tsis tau tshem tawm xeb thiab impurities los ntawm cov yeeb nkab steel nto ua ntej mus rau cov txheej txheem tom ntej. Cov txheej txheem no yuav zoo li yooj yim, tab sis seb nws puas ua tau zoo yuav tshwm sim tom qab ob peb xyoos ntawm kev ua haujlwm.
