1. Xuab zeb: tsom mus rau kev tshuaj xyuas cov xuab zeb qhov zoo ntawm cov qauv, cov khoom siv gradation, cov ntsiab lus av nkos, cov ntsiab lus ntawm cov av nkos, cov ntsiab lus noo noo, sundries, thiab lwm yam. cov xuab zeb yuav tsum tau txiav txim ua ntej los ntawm txoj kev "pom, pinching, rubbing thiab ntuav".

(1) "Saib", tuav ib txhais tes ntawm cov xuab zeb thiab muab faib rau hauv xib-teg ntawm koj txhais tes, thiab saib qhov sib xws ntawm kev faib cov ntxhib thiab cov xuab zeb zoo.Qhov sib npaug ntau dua qhov kev faib tawm ntawm txhua theem, qhov zoo dua;

(2) "Pinch", cov dej ntsiab lus ntawm cov xuab zeb yog pinched los ntawm tes, thiab qhov nruj ntawm cov xuab zeb yog pom tom qab pinching.Cov xuab zeb hnyav dua, cov dej ntau dua, thiab rov ua dua;

(3) "Xaiv", rub ib txhais tes ntawm cov xuab zeb ntawm koj txhais tes, txhuam nrog ob txhais tes, npuaj koj ob txhais tes maj mam, thiab pom cov av nkos nyob rau ntawm koj txhais tes.;

(4) "Ntev", tom qab cov xuab zeb yog pinched, muab pov rau hauv xib teg.Yog tias cov xuab zeb loj tsis xoob, nws tuaj yeem txiav txim siab tias cov xuab zeb zoo, muaj av nkos lossis muaj cov ntsiab lus dej siab.

2. Crushed pob zeb: tsom rau kev tshuaj xyuas cov pob zeb specifications, particle gradation, av nkos ntsiab lus, av nkos ntsiab lus, koob zoo li particle cov ntsiab lus, khib nyiab, thiab lwm yam., feem ntau yog nyob rau hauv intuitive txoj kev "pom thiab sib tsoo".

(1) "Saib" yog hais txog qhov loj tshaj qhov me me ntawm cov pob zeb crushed thiab qhov sib xws ntawm kev faib ntawm cov pob zeb crushed nrog ntau qhov sib txawv.Nws tuaj yeem txiav txim siab ua ntej seb qhov gradation ntawm lub pob zeb crushed yog qhov zoo los yog phem, thiab kev faib ntawm rab koob zoo li tuaj yeem kwv yees.Qib ntawm kev cuam tshuam ntawm cov pob zeb crushed ntawm kev ua haujlwm thiab lub zog ntawm pob zeb;

Cov ntsiab lus ntawm cov av nkos tuaj yeem txheeb xyuas los ntawm kev saib cov tuab ntawm cov hmoov av uas txuas rau saum npoo ntawm pob zeb;Lub degree ntawm grain faib nyob rau saum npoo ntawm cov pob zeb huv si tuaj yeem txheeb xyuas los ntawm kev sib xyaw nrog "sib tsoo" (ob lub pob zeb sib tsoo) txhawm rau txheeb xyuas qhov nyuaj ntawm pob zeb..

Xyuas seb puas muaj shale thiab daj ntawm daim tawv nqaij nyob rau hauv lub pob zeb, yog hais tias muaj ntau shale hais, nws yog tsis muaj.Muaj ob hom daj ntawm daim tawv nqaij.Muaj xeb ntawm qhov chaw tab sis tsis muaj av nkos.Cov khoom zoo li no muaj thiab yuav tsis cuam tshuam rau kev sib raug zoo ntawm pob zeb thiab mortar.

Thaum muaj av nkos daj nyob rau saum npoo ntawm cov khoom, cov khoom no yog qhov phem tshaj plaws, nws yuav cuam tshuam rau kev sib raug zoo ntawm cov pob zeb thiab cov mortar, thiab lub zog compressive ntawm cov pob zeb yuav raug txo kom tsawg thaum muaj cov khoom zoo li no.

3. Admixtures: pob zeb admixtures, los ntawm kev pom qhov muag ntawm cov xim, nws tuaj yeem txiav txim siab seb nws yog naphthalene (xim av), aliphatic (ntshav liab) lossis polycarboxylic acid (tsis muaj xim lossis lub teeb daj), ntawm chav kawm, kuj muaj naphthalene thiab rog Cov khoom (liab xim av) tom qab compounding kuj tuaj yeem txiav txim los ntawm qhov tsis hnov ​​​​tsw ntawm cov dej txo tus neeg sawv cev.

4. Admixtures: Lub sensory zoo ntawm ya tshauv yog tsuas yog txiav txim los ntawm txoj kev yooj yim ntawm "pom, pinching thiab ntxuav"."Saib" txhais tau tias saib cov duab ntawm cov hmoov tshauv ya.Yog hais tias lub particle yog spherical, nws ua pov thawj tias ya tshauv yog thawj cov pa taws tshauv, txwv tsis pub nws yog av tshauv.

(1) "Pinch", pinch nrog tus ntiv tes xoo thiab ntiv tes ntiv tes, hnov ​​​​qhov qib ntawm lubrication ntawm ob tus ntiv tes, qhov ntau lubricated, qhov zoo dua cov yoov tshauv yog, thiab lwm yam, lub thicker (fineness) yog.

(2) "Xaiv", rub ib txhais tes ntawm cov tshauv ya nrog koj txhais tes thiab tom qab ntawd yaug nrog dej.Yog hais tias cov seem txuas nrog lub xib teg ntawm tes yog yooj yim ntxuav, nws tuaj yeem txiav txim siab tias qhov poob ntawm qhov hluav taws kub ntawm cov tshauv ya yog me me, txwv tsis pub cov residue kuj me me.Yog tias nws nyuaj rau ntxuav, nws txhais tau hais tias qhov poob ntawm qhov hluav taws kub ntawm ya tshauv yog siab.

Cov tsos xim ntawm ya tshauv tuaj yeem cuam tshuam qhov zoo ntawm ya tshauv.Cov xim yog xim dub thiab cov ntsiab lus carbon siab, thiab cov dej xav tau ntau dua.Yog tias muaj qhov xwm txheej txawv txav, qhov kev sib xyaw sib xyaw yuav tsum tau ua raws sij hawm los xyuas qhov cuam tshuam ntawm kev siv dej, kev ua haujlwm, kev teeb tsa lub sijhawm thiab lub zog.

Cov xim ntawm cov hmoov slag yog cov hmoov dawb, thiab cov xim ntawm cov hmoov slag yog grey los yog dub, qhia tias cov hmoov slag yuav tov nrog steel slag hmoov los yog ya tshauv nrog tsawg ua haujlwm.
