1. Kev faib tawm ntawm EPS foaming tshuab
Muaj ntau hom thiab cov qauv ntawm cov tshuab foaming, tab sis raws li lub hauv paus ntsiab lus ntawm foaming, tsuas muaj peb hom kev siv dav: high-speed impeller type, high-pressure air type, thiab medium thiab low pressure blast type. Qhov sib txawv ntawm tib hom tsuas yog qhov sib txawv ntawm nws cov khoom siv ntxiv thiab kev tswj tsis siv neeg. Cov qauv ntawm cov foamed ib feem yog qhov zoo ib yam.
Qhov thib ob, lub hauv paus ntsiab lus ntawm EPS foaming tshuab
Lub hauv paus ntsiab lus ntawm foaming yog los qhia cov huab cua rau hauv cov tshuaj foaming agent, txawm tias hom foaming tshuab nws yog dab tsi. Kev hloov pauv ntawm cov qauv sib txawv yog tias cov nyhuv sib txawv, thiab txoj kev qhia cov roj kuj txawv.
EPS foaming tshuab kev faib tawm, txoj cai thiab txheej txheem
Muaj ob yam tsim nyog rau kev tsim ua npuas ncauj, ib qho yog foaming agent tov, thiab lwm yam yog huab cua, ob yam no yog inseparable. Yog tias tsis muaj tshuaj tua kab mob, tsis muaj cov yeeb yaj kiab ua kua yuav tsim nyob ib puag ncig cov pa roj, thiab yuav tsis muaj npuas. Yog tsis muaj roj, foaming agent daws ib leeg tsis tuaj yeem tsim foams.
Nyob rau hauv lub npuas tsim system, cov roj yog lub dispersed theem, cov roj yog dispersed nyob rau hauv cov kua los ua npuas, cov foaming agent tov yog dispersion nruab nrab, thiab ntau npuas tsim npuas. Ntxiv nrog rau cov khoom ntawm lub tshuab tshuab, kev qhia txog cov roj hauv cov tshuab tshuab tshuab kuj yog ib qho tseem ceeb. Lub tshuab foaming txais ib txoj hauv kev los qhia cov roj rau hauv cov kua, uas yog, kev taw qhia cov roj rau hauv cov kua yuav tsum ua kom tiav los ntawm lub tshuab foaming.
3. EPS foaming tshuab txheej txheem
1. Kev pub mis thiab kev sib xyaw: Ntxiv cov cement, foaming agent, thiab kev faib tawm, cov ntsiab lus, thiab cov txheej txheem lub zog ntawm EPS foaming tshuab mus rau tov khoom los ntawm kev pub mis, thiab sib tov qhuav rau 30 vib nas this. ;
2. stirring: Ntxiv cov dej sov rau kev faib tawm, txoj cai thiab txheej txheem ntawm EPS foaming tshuab rau hauv lub tov khoom, thiab do rau 2 feeb; ntxiv cov foaming tus neeg sawv cev rau kev faib tawm, lub hauv paus ntsiab lus thiab txheej txheem ntawm EPS foaming tshuab rau lub tov khoom thiab do rau 8-15 vib nas this;
3. Txhaj foaming: Tam sim ntawd txhaj cov slurry rau hauv pwm rau foaming;
4 Kev kho qhov pib: Tom qab kev txhaj tshuaj molding tiav, cia nws sawv ntsug rau ob peb teev rau kev kho thawj zaug;
5 Demoulding: thawj qhov chaw ntawm cov npuas dej cement thaiv vaj huam sib luag tiav, thiab demoulding tom qab ncav lub zog thawj zaug;
6 Txiav: Tom qab demoulding, qee lub zog ntawm foamed cement rwb thaiv tsev boards tuaj yeem raug txiav, thiab txiav cov ntsiab lus tuaj yeem hloov kho raws li qhov xav tau ntawm cov hniav txiav;
7 Kev tu cov khoom tiav: Lub voj voog tu tsis pub tsawg tshaj 7 hnub.
