Anti-frost additives nyob rau hauv mortar hnub no yog heev nquag siv nyob rau hauv kev tsim kho. Lawv qhov zoo li ua rau nws tuaj yeem txhim kho cov tsev thiab cov tsev nyob txhua lub sijhawm ntawm lub xyoo yam tsis muaj kev puas tsuaj rau cov qauv zoo yav tom ntej.
Yuav tsum siv tshuaj tiv thaiv kab mob ntxiv
Yog tias koj nchuav cov tshuaj uas tsis muaj cov tshuaj ntxiv tshwj xeeb ntawm qhov kub thiab txias, tom qab ntawd nws cov tawv tawv yuav tshwm sim maj mam, vim qhov kev ncua ntawm cov dej ntawm cov cement. Thaum qhov kub nce mus txog -3 ° C, cov kua uas muaj nyob hauv cov pob zeb pib tig mus rau hauv dej khov, thiab cov txheej txheem hydration nres. Thaum cov tshuaj thaws, tag nrho cov txheej txheem rov pib dua, thiab cov qauv txuas ntxiv kom muaj zog. Tab sis yog hais tias cov dej khov tshwm sim yuav luag tam sim ntawd tom qab pouring, lub thawing ntawm cov pob zeb yuav tsum tau nrog los ntawm kev nrhiav tau ntawm ib tug monolith ntawm ib tug xoob qauv, qhov no yuav ua rau insignificant lub zog, ntxiv rau, cov qauv yuav tsis resistant rau Frost.
Cov tshuaj tiv thaiv kab mob Frost tsuas yog siv los xyuas kom meej tias cov txheej txheem hardening tshwm sim ib txwm nyob rau hauv cov tshuaj nchuav rau lub caij ntuj no. Anti-freeze agents muaj peev xwm txo qis qhov khov ntawm cov kua, yog li cov pob zeb yuav nce ntxiv zog ntawm qhov kub thiab txias.
Anti-frost additive - ammonia dej
Ammonia dej ua raws li kev lag luam muaj txiaj ntsig zoo ntxiv rau pob zeb. Nws muaj cov yam ntxwv zoo dua qub thaum piv nrog cov tshuaj aqueous ntawm calcium chloride thiab potash. Yog li, nws qhia tau hais tias qhov tsis txaus ntseeg feem pua ntawm kev nthuav dav, uas ua rau nws tsis txaus ntshai heev ntawm cov xwm txheej deformation uas tuaj yeem tshwm sim thaum tsim cov dej khov.
Cov lus piav qhia los tiv thaiv kev tiv thaiv kab mob yog siv rau hauv cov tshuaj hauv qhov nyiaj uas tau hais los ntawm cov cai ntawm huab cua sab nraud. Feem ntau, cov dej ammonia raug xaiv dua lwm cov tshuaj ntxiv ntxiv vim nws tsis ua rau cov khoom siv ntxiv. Cov additive tsis muaj peev xwm txo tau cov nplaum zoo ntawm qhov cuab lub zog nrog mortar, tsis txo lub peev xwm ntawm cov qauv rau Frost tsis kam, thiab tsis tuaj yeem ua rau cov tsos ntawm efflorescence thiab txhua yam stains ntawm lub hauv paus ntawm cov qauv. Ammonia dej qeeb lub sij hawm kom txog thaum cov cements tawv, uas ua rau nws yooj yim rau nteg cov sib tov, uas yuav kav ntev li 4-7 teev.
Ntawm cov tshuaj tiv thaiv kab mob ntxiv
Nws tsim nyog nco ntsoov ua ntej ntxiv cov tshuaj tiv thaiv kab mob ntxiv rau cov tshuaj uas lawv muaj peev xwm txav tau thiab tsim cov pawg hauvqee qhov chaw, xws li hauv cov tav lossis cov khaubncaws sab nraud povtseg. Tom qab ntawd, lawv tuaj yeem tau txais cov qauv ntawm cov muaju. Txhawm rau tshem tawm qhov no, koj yuav tsum tsis txhob pib ua haujlwm thaum qhov kub thiab txias tuaj yeem hloov pauv ntau zaus thaum nruab hnub. Qhov no yog qhov tseeb tshwj xeeb tshaj yog thaum qhov kub hloov pauv ntawm qhov qis mus rau qhov zoo. Cov yam ntxwv ntawm cov huab cua no yog qhov zoo rau lub caij nplooj zeeg-caij nplooj ntoos hlav lossis lub caij ntuj no thaws.
Qee cov tshuaj tiv thaiv kab mob hauv cov tshuaj khib nyiab tuaj yeem ua rau kev puas tsuaj ntawm cov pob zeb ua tiav. Qhov no feem ntau yog vim muaj peev xwm crystallization ntawm ntsev, uas tuaj yeem raug sau tseg hauv thaj chaw uas cov tshuaj ntxiv tau pom tias nyob rau hauv lub xeev muaj zog. Tom qab ntawd, qhov no tuaj yeem ua rau cov tsos ntawm kev tsim tsis xws luag. Qhov cuam tshuam rau cov xwm txheej zoo li no yog cov khoom siv ntxiv uas muaj potash thiab calcium nitrate ntawm cov khoom xyaw. Koj tuaj yeem tshem tawm cov teeb meem zoo li no los ntawm kev ua tib zoo suav cov ntawv xov xwm ntawm tus lej ntawm cov khoom ntxiv uas cuam tshuam nrog lub ntim thiab muaj pes tsawg leeg ntawm cov tshuaj, nrog rau cov xwm txheej sab nraud.
Caution
Qee cov tshuaj tiv thaiv kab mob hauv cov tshuaj khib nyiab (Astana yog ib lub nroog uas lawv tuaj yeem yuav tau) yuav tsum tsis txhob siv nrog cov pob zeb uas yuav raug cuam tshuam rau ib puag ncig txaus ntshai thaum ua haujlwm. Qhov no siv rau cov formulations uas muaj ob chav ntsev. Yog li, sodium thiab calcium chlorides ua kom muaj zog ntawm cov hlau, uas ua rau muaj feem ntau nyob rau hauv cov xwm txheej uas muaj cov av noo siab thiab muaj cov pa oxygen hauv huab cua. Tab sis yog siv nyob rau hauv tandem nrog additives txaus ntshai rau ntxiv dag zogcomplex compositions uas muaj steel corrosion inhibitors, ces qhov aggressiveness ntawm cov tshuaj chloride yuav txo tau. Yog li, yog tias nitrite ions ntxiv rau pob zeb (qhov loj piv HH: XK yog 1: 1), chloride ions yuav luag tsis txaus ntshai rau kev khaws cia cov yam ntxwv zoo ntawm kev txhawb nqa.
Pros of antifreeze additives
Los ntawm kev sib xyaw cov tshuaj tiv thaiv kab mob rau hauv mortar rau masonry los yog rau kev tsim kho ntawm lub hauv paus thiab lwm yam qauv, nrog rau cov tsev thiab cov qauv, koj tuaj yeem paub tseeb tias lawv:
- nce cov plasticity ntawm cov tshuaj;
- pab kev tsim kho ua haujlwm ntawm qhov kub thiab txias;
- nce cov nplaum zoo ntawm pob zeb;
- nce qhov ntom ntawm pob zeb;
- nce lub zog ntawm cov qauv tom qab kho;
- muab lub neej ntev rau cov qauv tsim.
Tus nqi ntawm cov tshuaj tiv thaiv kab mob ntxiv
Anti-frost additives nyob rau hauv cov tshuaj tej zaum yuav muaj cov nqi sib txawv, uas yuav nyob ntawm seb cov yam ntxwv zoo ntawm cov khoom xyaw, nws cov khoom xyaw thiab lwm yam. Piv txwv li, Lavxias teb sab-made Bitumast additive tuaj yeem yuav hauv lub thawv yooj yim, qhov ntim ntawm 13.5 kg, uas tus neeg siv khoom yuav tsum them 638 rubles.
Yog tias koj npaj siab yuav ua haujlwm hauv lub caij ntuj no, ces koj yuav xav tau cov tshuaj tiv thaiv Frost ntxiv hauv cov tshuaj. Kazan (xws li Prioritet LLP) muaj xws li cov khoom lag luam los ntawm German chaw tsim khoom rau 285 rubles (10 l).
Koj tuaj yeem xaiv qhov sib xyaw los ntawmmanufacturers, uas yog ntau rau koj nyiam nyob rau hauv cov nqe lus ntawm tus nqi. Tom qab tag nrho, cov khoom ntxiv los ntawm ntau qhov chaw ntawm lub ntiaj teb tau nthuav tawm hauv kev tsim kho kev lag luam niaj hnub no.
