Txhawm rau teb cov lus nug no, peb yuav tsum xub nkag siab tias qhov tawg yog dab tsi? Thiab dab tsi yog hlau ua npuas ncauj?
1. Cov khoom tawg feem ntau yog muab faib ua lub cev thiab tshuaj lom neeg tawg
- Lub hauv paus ntsiab lus ntawm lub cev tawg:
Lub cev tawg yog tshwm sim los ntawm kev hloov ntawm lub cev (xws li kub, ntim, siab, thiab lwm yam), thiab cov khoom thiab tshuaj lom neeg muaj pes tsawg leeg ntawm cov khoom tawg tsis hloov ua ntej thiab tom qab tawg.
Cov khoom tawg hluav taws xob feem ntau yog los ntawm lub zog shrinkage, lub zog hloov pauv, lub zog kinetic, ntws lub zog, thermal zog, hluav taws xob hluav taws xob, thiab lwm yam.
Kev tawg ntau dhau ntawm cov txheej txheem tsis muaj tshuaj lom neeg, tawg ntawm cov kua roj gasification, tawg ntawm cov roj liquefied thiab cov kua dej superheated, cua sov ntawm kev tawg, kub ntawm dilution, cua sov ntawm adsorption, tawg tshwm sim los ntawm sab nraud cua sov, tawg tshwm sim los ntawm cov dej ntws, tawg tshwm sim los ntawm overcurrent. , tawg tshwm sim los ntawm qhov chaw tso tawm Air explosions tag nrho yog nyob rau hauv qeb ntawm lub cev explosions.
- Cov ntsiab lus ntawm chemical tawg:
Cov tshuaj lom neeg tshwm sim los ntawm cov tshuaj tiv thaiv.
Txawm hais tias nws yog ib qho kev sib xyaw ntawm cov hluav taws kub thiab cua, lossis cov khoom tawg (xws li dynamite), cov khoom tawg ntawm cov tshuaj lom neeg yog qhov tsis ruaj khov, uas yuav ua rau muaj kev kub ntxhov exothermic nyob rau hauv qhov kev txiav txim ntawm qee lub zog sab nraud. , tsim kom muaj qhov kub thiab txias siab, thiab tsim kom muaj kev puas tsuaj loj.
- Tsib yam hauv qab no yuav tsum tau ua raws li:
A. Cov khoom tawg yooj yim uas muab lub zog, uas yog, tawg;
B. combustion accelerants (oxidants), xws li oxygen, cua;
Cov khoom combustible thiab accelerant yog sib tov sib npaug;
D. Cov sib tov yog muab tso rau hauv ib qho chaw kaw (surrounded);
Ua kom muaj zog txaus.
2. Dab tsi yog hlau ua npuas ncauj?
Hlau ua npuas ncauj yog ib yam ntawm cov hlau ntxeem tau nrog ib tug porosity ntawm ntau tshaj 90% thiab ib tug tej yam lub zog thiab hardness. Cov khoom no yog cov khoom siv hlau uas muaj cov pore ua npuas ncauj, qhov porosity siab dua li cov hlau sintered porous zoo tib yam, thiab qhov pore loj tuaj yeem ncav cuag 7 hli.
Hlau ua npuas ncauj yog ob-theem cov khoom sib xyaw ua ke ntawm pore dispersed theem thiab hlau matrix skeleton nruam theem thiab theem, thiab nws cov khoom nyob ntawm qhov cuam tshuam ntawm cov hlau matrix, porosity, pore qauv thiab txheej txheem kev npaj.
3. Hlau ua npuas ncauj yog siv nyob rau hauv tawg-pov thawj nplaim retardant
Hlau ua npuas ncauj muaj cov kua dej zoo permeability thiab zoo hluav taws kub. Nws tuaj yeem muab tso rau hauv cov kav dej uas nqa cov roj hluav taws xob lossis cov kua dej kom tsis txhob tawg los ntawm kev nqus cua sov kom tsis txhob kis cov nplaim taws.
Cov khoom no yog tsim rau acetylene, oxygen nplaim taws welding thiab roj txiav tshuab, mining motors thiab fais fab hloov, roj refining thiab combustible gas pipelines, burner systems, roj thiab roj rov qab systems, cua sov furnaces, gas purification systems, thiab lwm yam. siv los ua hluav taws-pov thawj thiab tawg-pov thawj muab tub lim rau cia tank xws li roj liquefied thiab roj.
