Dab tsi yog Lub Ntsiab Cai Ntawm Kev Ua Txhaum Txhaum Cai

Shrinkage-compensating qhob compensates rau pob zeb qhuav shrinkage, densifies lub pob zeb, thiab txhim kho nws impermeability. Hauv kev tsim vaj tsev engineering, nws tsuas yog siv rau kev ua dej tsis sib haum thiab tawg ua haujlwm. Nws yog feem ntau siv los npaj qib high-qib waterproof pob zeb thiab kom tsim nyog ncua qhov sib nrug ntawm cov pob qij txha expansion los yog kev tsim kho pob qij txha.

Cov ntaub ntawv tseem ceeb:

Hom:Calcium sulfoaluminate qhob expansive agent

Yam ntxwv:

Tsis muaj sodium ntsev, yog li tsis txhob alkali-tag nrho cov tshuaj tiv thaiv hauv pob zeb

Zoo durability

ruaj khov expansive kev ua tau zoo

Nruam lub zog nce

Kev siv:Los ntawm kev sib xyaw 8% -12% ntawm tus neeg sawv cev nthuav dav rau hauv cov cement, shrinkage-compensating pob zeb tuaj yeem npaj tau, txhim kho qhov tawg tsis kam thiab tsis muaj peev xwm ntawm cov pob zeb ua vaj tse. Qhov no tuaj yeem tshem tawm qhov xav tau rau kev ua haujlwm sab nraud ntawm cov dej tsis zoo, txuas ntxiv qhov kev ncua deb ntawm kev tsim kho cov pob qij txha, thiab tiv thaiv qhov kub thiab txias qhov sib txawv ntawm cov pob zeb loj thiab lub zog loj.

Daim Ntawv Thov Ntau:

Underground Structures:Subways, underground chaw nres tsheb, underground warehouses, tunnels, mines, pej xeem tiv thaiv tej yaam num, foundations, thiab lwm yam.

Dej Tank thiab Ntim:Cov pas dej da dej, cov pas dej da dej, cov dej yees, cov tso tsheb hlau luam, cov thawv loj, granaries, roj tank, warehouses hauv qhov tsua, thiab lwm yam.

Infrastructure:High-strength txoj kev pavements, choj pob zeb nto, culverts, thiab lwm yam.

Precast Elements:Thauj tog rau nkoj sib txuas rau thav duab cov pob qij txha, cov kav dej sib txuas, cov khoom siv rau cov khoom siv tom qab tensioned precast, backfilling rau kev tsim kho pob qij txha, magma grouting cov ntaub ntawv.

Cov khoom siv cement:Self-stressing, prestressed, thiab steel-sleeved prestressed qhob kav, slabs, kab, kab teeb, waterproof ru tsev panels, thiab lwm yam.

Machinery Foundations:Grouting ntawm thauj tog rau nkoj bolts, hauv paus, thiab pob zeb hauv paus tsis muaj shrinkage.

Tube Linings:Kev tiv thaiv mortar linings rau cam khwb cia hlau thiab steel kav.

Rigid Waterproof Roofs:Waterproofing mortar txheej, damp-proofing mortar txheej, thiab lwm yam.

Lwm tus:Chaw ntau pob, sculptures hauv nroog, tsev cia puav pheej, tsev so, thiab lwm yam.

Txoj kev siv:

Pom zoo Dosage:8% -12%. Rau kev tsim kho cov pob qij txha thiab cov cheeb tsam ntxiv dag zog, nce cov tshuaj kom tsim nyog.

Waterproofing Technology:Cov pob zeb npaj nrog tus neeg sawv cev nthuav dav tuaj yeem siv cov txheej txheem ntawm tus kheej-waterproofing thev naus laus zis, sib txuas cov txheej txheem thiab cov dej tsis zoo, ua kom yooj yim rau lub tsev tsim los ntawm kev tshem tawm cov dej tsis zoo sab nraud.

Kev tsim kho tshuab:Siv super-ntev reinforced pob zeb seamless tsim thiab kev tsim kho cov txheej txheem los txo cov txheej txheem kev tsim kho, ua kev tsim kho yooj yim dua thiab ua rau lub sijhawm siv sijhawm luv. Tsis muaj kev tsim kho cov pob qij txha sab laug, tso cai rau thaj chaw loj-thaj chaw txuas ntxiv pob zeb. Nws kuj tseem siv tau rau kev kho cov pob qij txha hauv cov pob zeb zoo tib yam.

Cov kev ceev faj:

Kev noj tshuaj kom raug:Ntawm qhov chaw tsim kho lossis kev cog cog, kev siv tshuaj yuav tsum ua raws li qhov kev txiav txim siab sib xyaw rau cov pob zeb ua kom qis-compensating. Cov cuab yeej ntsuas yuav tsum yog qhov tseeb. Kev noj tshuaj tsis txaus yuav tsis ua tau raws li qhov yuav tsum tau ua kom txo qis-compensating, thaum noj ntau dhau tuaj yeem ua rau cov pob zeb ua kom puas.

Mixing Sijhawm:Lub sijhawm sib xyaw rau pob zeb nrog tus neeg sawv cev nthuav dav yuav tsum yog 30 vib nas this ntev dua li cov pob zeb zoo tib yam. Qhov kub ntawm cov pob zeb sib xyaw yuav tsum qis dua 30 degree, thiab lub caij nplooj zeeg dawb yuav tsum tswj tsis pub dhau 2 meters thaum lub sij hawm nchuav. Vibrating yuav tsum zoo ib yam, ntom, tsis dhau-vibration, nyob rau hauv-vibration, los yog qhov chaw uas ploj lawm.

Secondary Finishing:Ua cov txheej txheem thib ob ua ntej qhov chaw zaum kawg ntawm cov pob zeb txhawm rau tiv thaiv qhov tawg ntawm qhov tawg.

Kho:Curing yog qhov tseem ceeb rau kev ua vaj tse nrog tus neeg sawv cev nthuav dav. Nyob ntawm qhov kub thiab txias, dej cov pob zeb kom sai li sai tau kom lub ntsej muag tsis tu ncua ntub dej tsawg kawg 7 hnub. Rau kev tsim kho kub tsis zoo, xyuas kom cov pob zeb kub nkag mus rau hauv pwm yog siab dua 5 degree, thiab tam sim ntawd siv cov yas zaj duab xis thiab cov ntaub ntawv rwb thaiv tsev rau rwb thaiv tsev thiab noo noo tom qab nchuav.

Kev ntsuas tom qab dej:Tom qab pouring, backfill lub qab daus nrog txiv qaub av kom sai li sai tau, thiab nruab ib waterproof thiab rwb thaiv tsev txheej ntawm lub ru tsev sai li sai tau.
