Taw qhia ntawm yoov tshauv cenosphere
ya tshauv cenosphere yog hom ya tshauv hollow pob uas tuaj yeem ntab saum dej. ya tshauv cenosphere tawm dawb, nrog cov phab ntsa nyias thiab hollow, hnyav heev, 160-400 kg/m3, qhov loj me me txog li 0.1-0.5 hli, thiab qhov chaw raug kaw thiab du. Tsawg thermal conductivity, refractoriness≥1610℃, nws yog cov khoom siv hluav taws xob tiv thaiv hluav taws xob zoo heev, siv dav hauv kev tsim cov khoom hnyav thiab cov roj drilling. Cov tshuaj lom neeg muaj pes tsawg ntawm cov hmoov tshauv cenosphere feem ntau yog silica thiab aluminium oxide. Nws muaj ntau yam ntxwv xws li cov khoom me me, hollow, lub cev hnyav, lub zog siab, hnav tsis kam, tiv taus kub, tiv thaiv cua sov, rwb thaiv tsev thiab nplaim hluav taws.
Ya tshauv cenosphere muaj qhov zoo hauv qab no
1. Tus nqi ntawm cov tshuaj me me / qhov muaj peev xwm ntxiv tau yog qhov zoo: vim tias nyob hauv ib qho twg, cov duab kheej kheej muaj qhov me me tshwj xeeb tshaj plaws hauv cheeb tsam, thiab ya tshauv cenosphere xav tau cov tshuaj tsawg tshaj plaws.
2. Tsawg viscosity/txhim kho fluidity: Tsis zoo li cov lus tsis sib xws, ya tshauv cenosphere tuaj yeem yooj yim yob ntawm ib leeg. Qhov no ua rau cov txheej txheem siv ya tshauv cenosphere muaj qis viscosity thiab zoo fluidity. Ntxiv mus, kev txau dej ntawm lub kaw lus kuj tau raug txhim kho;
3. Hardness/puas ua haujlwm: ya tshauv cenosphere yog hom muaj zog thiab tawv microspheres, uas tuaj yeem txhim kho qhov nyuaj, txhuam tsis kam thiab txhuam tsis kam ntawm txheej;
4. Cov cua sov ua kom zoo tshaj plaws: vim yog qhov hollow sphere qauv ntawm ya tshauv cenosphere, nws muaj cov cua sov zoo heev thaum ua cov xim;
5. Inertness: ya tshauv cenosphere yog tsim los ntawm cov khoom xyaw inert, yog li lawv muaj kev ua haujlwm tau zoo, tiv taus huab cua, tiv taus xeb thiab tiv taus tshuaj lom neeg;
6. Opacity: Hollow spherical shape of the fly ash cenosphere qeeb thiab ua rau lub teeb tawg, uas ua rau muaj kev nce hauv kev zais lub zog ntawm cov xim;
7. Dispersibility: Lub dispersion ntawm ya tshauv cenosphere yog tib yam li cov ntxhia pob zeb. Vim yog cov phab ntsa tuab thiab lub zog siab ua kom muaj zog ntawm cov hmoov tshauv cenosphere, nws tuaj yeem tiv taus kev ua txhua yam ntawm cov khoom sib tov, tshuab txuas ntxiv thiab tshuab moulding;
Lwm yam kev siv ya tshauv cenosphere
1. Refractory rwb thaiv tsev cov ntaub ntawv uas; xws li cov cib sib tsoo sintered refractory cib, cov cib uas tsis raug rho tawm hluav taws, cov rwb thaiv tsev rwb thaiv tsev, cov rwb thaiv tsev yeeb nkab, cov hluav taws pov thawj txheej txheej, rwb thaiv tsev dhau los, cov rwb thaiv tsev qhuav hmoov, rwb thaiv tsev hnyav thiab hnav-tiv taus iav fiber ntau ntxiv yas,
2. Kev lag luam roj av; oilfield cementing kom txo tau qhov to, pipeline anticorrosion thiab rwb thaiv tsev, subsea oilfields, ntab khoom, roj zoo drilling av nkos reducers, roj thiab cov raj xa dej, thiab lwm yam.
3. Rwb thaiv tsev cov ntaub ntawv; yas ua kom puv, kub thiab insulators siab, thiab lwm yam,
4. Aerospace thiab kev tsim kho chaw; cov ntaub ntawv sib xyaw saum npoo rau lub hnub qub, foob pob hluav taws, thiab lub dav hlau, txheej tiv thaiv hluav taws los ntawm lub hnub qub, cov cuab yeej siv hauv nkoj, nkoj, nkoj hauv hiav txwv tob, thiab lwm yam;
5. Hmoov hlau metallurgy: Nws tau sib xyaw nrog lub teeb hlau xws li txhuas thiab magnesium ua cov hlau ua npuas ncauj. Piv nrog lub hauv paus hlau, cov khoom siv sib xyaw no muaj cov yam ntxwv ntawm qhov ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntaws
