PA80 refractory kua nplaum feem ntau yog siv ntawm cov cib thiab cib nyob rau hauv cov ntaub ntawv ntawm qhov kub thiab txias kev twb kev txuas cov khoom, nyob rau hauv ib tug dav dav, kuj yuav muab teev raws li kub refractory mortar, PA80 refractory kua nplaum thiab zoo tib yam refractory mortar txawm nyob rau hauv zoo thiab nqi, txawv heev.
Qhov sib txawv tshaj plaws ntawm ob yog qhov sib txawv ntawm kev siv qhov kub thiab txias, qhov kev tsim kho ntawm cov khoom siv hluav taws xob zoo li qub tuaj yeem yog cov khoom siv hluav taws xob zoo tib yam, lossis cov phosphate refractory mortar, thiab cov dynamic kiln hauv ob sab phlu yog qhov zoo tshaj plaws los siv PA80 refractory kua nplaum. dynamic mechanical siab thiab kiln kev nyuaj siab, los tiv thaiv lub cib poob tawm ntawm txoj kev sib hloov.
Tseem muaj ntau yam zoo tib yam refractory mortar, tag nrho raws li qhov zoo ntawm kev siv cov refractory cib nrog tib cov ntaub ntawv ntawm kev sib koom refractory mortar, refractory mortar muab faib ua av nplaum thiab siab txhuas, silicon carbide, silicon, magnesium thiab lwm yam sib txawv series. , yog cov khoom sib koom ua ke ntawm masonry refractory cib ntawm cov khoom sib txawv.
PA80 refractory kua nplaum yog siv tshwj xeeb binder thiab hmoov, hmoov thiab av nplaum zoo tib yam muaj kev hloov zoo, cov av nkos feem ntau yog 160-180 lub hom phiaj hmoov thiab av nplaum npaj. Lub PA80 refractory kua nplaum yog ua los ntawm cov hmoov, ntxiv cov hmoov ultrafine, thiab ntxiv ntau yam tshwj xeeb binders rau boil, boil lub kua nplaum nrog ib lub thoob ib leeg, kev siv cov nyhuv kub yog zoo kawg li.
Lub adhesion ntawm refractory mortar yog qhov tseem ceeb heev. Kev sib raug zoo tsis zoo yuav cuam tshuam rau kev sib koom ua ke ntawm firebrick pob qij txha thiab txo cov kev pab cuam lub neej ntawm firebrick. Ordinary refractory mortar thiab PA80 refractory kua nplaum yuav tsum muaj dynamic fluidity thiab plasticity. Tsis muaj fluidity thiab adhesion, cov pob qij txha ntawm cov cib thiab cov cib thaum lub sij hawm tsim kho yuav tsis nruj, thiab qhov tshwm sim ntawm ntog bricks yuav tshwm sim ntawm qhov kub thiab txias.
Lub thermal expansion lossis shrinkage ntawm PA80 nplaum yog zoo dua li ntawm cov tshuaj refractory zoo tib yam, thiab nws yuav tsis cais cov refractory cib los yog ua rau cov av nplaum tawg. Kev ncaj ncees thiab nruj thiab kev sib koom ua haujlwm zoo dua. Lub adhesion ntawm zoo tib yam refractory mortar yog zoo nyob rau hauv nruab nrab thiab tsis kub cheeb tsam, thiab lub zog yog zoo nyob rau hauv qis kub, thaum lub PA80 nplaum yuav nce nrog rau qhov kub thiab txias, thiab lub zog ntawm cib kev koom ua ke yuav ua denser nrog rau qhov nce. kub.
PA80 refractory kua nplaum thiab refractory mortar raug xaiv raws li qhov kub thiab txias thiab txoj hauj lwm ntawm qhov zoo li qub thiab dynamic kiln hauv ob sab phlu, thiab cov khoom sib txawv ntawm cov firebrick.
