Niaj hnub no, ntau yam khoom siv niaj hnub no tau nthuav tawm ntawm kev tsim kho kev lag luam, kev siv uas, vim yog lawv lub cev thiab cov yam ntxwv zoo tshaj plaws, pab txhawb kom ua tau zoo dua thiab nrawm dua ntawm txhua hom haujlwm - los ntawm kev sib dhos ua kom tiav.
Ib qho ntawm cov no yog cov nplaum nplaum, tsis tas yuav teeb tsa lub qhov cub lossis lub qhov cub yog qhov tsis tseem ceeb tam sim no . Hauv kab lus no peb yuav qhia koj txhua yam txog cov khoom siv hauv tsev no, piav qhia nws cov yam ntxwv, ntau yam, cov npe nrov, ntxiv rau thaj chaw ntawm kev thov.
Nqe lus piav qhia
Adhesive mastic yog ib hom khoom siv hauv tsev uas yog nyob rau qeb ntawm cov nplaum. Cov khoom no yog tus yam ntxwv los ntawm kev ua haujlwm zoo heev. Nws muaj qee tus yam ntxwv thiab cov yam ntxwv uas tau hais meej meej hauv GOSTs thiab raug tswj los ntawm cov ntaub ntawv tswj hwm no.
Raws li GOST 24062-80 Roj hmab nplaum nplaum mastics. Cov xwm txheej zoo”cov khoom siv yuav tsum muaj qee yam kev ntsuas.
- Kev sib txuas lub zog - los ntawm 0, 12 MPa (kgf / cm²) mus rau 0, 32 MPa (kgf / cm²). Qhov ntsuas no nyob ntawm hom tshuaj mastic thiab lub sijhawm gluing.
- Viscosity-2-9 (20-90) P;
- Cheebtsam hloov pauv hauv cov muaj pes tsawg leeg - tsis ntau dua 45%;
- Kev nqus dej - ntawm 0.5 txog 1%.
Cov khoom siv ntsuas xws li ntom ntom, ntsuas hauv kg ib m3 (kilogram ib cubic meter), nyob ntawm hom tshuaj nplaum nplaum.
Cov nplaum nplaum, lub cev thiab cov txuj ci uas ua tau raws cov qauv, muaj daim ntawv pov thawj ntawm kev ua raws. Cov ntaub ntawv no lees paub nws qhov tsim nyog rau kev siv.
Cov khoom siv muaj tus lej zoo, ntawm qhov uas nws tsim nyog sau cia:
- siab zog;
- zoo heev adhesion rau lwm cov ntaub ntawv, tiav thiab vov tsev;
- siab coefficient ntawm bio- thiab dej tsis kam;
- tiv taus kub heev;
- kev pab lub neej ntev - cov tuam txhab txhim khu kev qha uas tsim cov khoom lag luam zoo muab kev lees paub yam tsawg 10 xyoo;
- elasticity;
- siab viscosity - qhov no tso cai rau cov khoom siv rau txhua hom nto, yog li ua kom muaj qhov dav ntawm nws daim ntawv thov.
Yav dhau los, rau kev tsim cov nplaum nplaum, tsuas yog siv cov ntoo ntawm tsob ntoo mastic. Tab sis kev tsim cov khoom no yog siv sijhawm ntau heev thiab cov khoom siv, txij li cov khoom pib - cov kua roj hmab ntawm tsob ntoo - yog kim heev. Tias yog vim li cas pheej yig dua cov ntaub ntawv raw tau siv hauv kev tsim khoom niaj hnub no rau kev tsim cov nplaum nplaum:
- roj hmab hluavtaws;
- hnyav;
- muab tub lim;
- polymer cob.
Tag nrho cov ntaub ntawv no muaj cov khoom zoo thiab cov khoom zoo, yog li cov nplaum ua los ntawm lawv yog qhov ua tau tsis muaj qhov qis dua li uas ua los ntawm cov roj hmab ntuj.
Hom kev txheeb xyuas
Muaj ntau hom nplaum polymer resins uas tau siv niaj hnub no rau kev kaw qhov rooj qhib, hauv pem teb, tso cov vuas thiab yooj yim rau kev tiv thaiv dej. Kiag li txhua yam ntawm cov mastic muaj cov nplaum ua haujlwm siab thiab kwv yees tib yam muaj pes tsawg leeg. Cia peb ua tibzoo saib ntawm cov hom tseem ceeb ntawm cov tshuaj.
Bituminous . Cov roj bitumen yog cov khoom siv tau ntau yam uas feem ntau siv hauv cov txheej txheem ntawm cov ru tsev, teeb tsa cov pa thaiv thiab cov khoom tiv thaiv dej. Nws yog cua sov thiab tiv taus ya raws, khov, ywj, ruaj thiab txhim khu kev qha. Muaj cov ntawv bituminous, tshuaj tua kab mob, tshuaj tua kab thiab tshuaj tua kab.
Shale sealing tsis kho MSU . Cov muaj pes tsawg leeg suav nrog cov khoom lag luam roj av, cov tshuaj ntxiv polymer, cov yas thiab cov muab tshuaj txhuam. Nws yog siv rau kev ntim thiab ntim cov iav.
-
Refractory . Lub hauv paus ntawm cov khoom yog cov tshuaj inorganic. Tuav tau qhov kub siab heev, uas yog vim li cas cov khoom siv hluav taws xob polymer refractory tau siv rau hauv cov txheej txheem ntawm rwb thaiv tsev rauv taws thiab cov nkev nkev.
Adhesive raws li FAED . Nws yog cov nplaum ua kom sov-resistant nplaum mastic. Hom tshuaj no tuaj yeem siv hauv ib puag ncig acidic thiab alkaline.
Muaj lwm hom nplaum nplaum rau ntawm kev ua lag luam: waterproofing acrylic, butyl roj hmab, soundproofing, ru tsev.
Hom nrov
Ntawm cov chaw tsim khoom tam sim no ntawm cov nplaum nplaum, nws tsim nyog sau cia:
- "Terracotta";
- Neomid Supercontact;
- Calorygeb;
- Tytan;
- Collafeu.
Txhua lub npe saum toj no tau lees tias muaj txiaj ntsig zoo thiab ua haujlwm ntev ntawm lawv cov khoom, uas, ua ntej nkag mus rau cov neeg siv khoom lag luam, hla tag nrho cov kev kuaj sim tsim nyog, ua raws li cov cai thiab cov qauv, thiab tau ntawv pov thawj.
Cov ntawv thov
Vim nws cov khoom zoo heev, cov txheej txheem kev ua haujlwm siab thiab ntau yam khoom sib txawv, thaj tsam ntawm kev siv cov nplaum nplaum yog dav thiab sib txawv.
Nws yog qhov xav tau hauv kev kho cov plag tsev, rau gluing cov khoom siv hauv tsev lossis tiv thaiv lub ru tsev.
Rau cov cuab yeej thiab kho kom zoo nkauj ntawm lub qhov cub thiab lub qhov cub, ob tus kws tshaj lij thiab cov kws tshaj lij ntawm kev kho vaj tsev kuj xaiv mastic.
Feem ntau, cov nplaum no siv thaum txhim kho:
- hauv pem teb npog;
- cov ntaub ntawv tiav;
- phab ntsa ntsiab;
- vov tsev.
Rau txhua hom kev tsim kho ua haujlwm, muaj cais hom nplaum nplaum, uas muaj qee yam khoom thiab yam ntxwv . Kev siv nws ua rau nws muaj peev xwm ntseeg tau txuas cov ntawv, pobzeb, pem teb thiab cov khoom vov tsev nrog txhua hom hauv paus. Qhov tseem ceeb yog xaiv qhov zoo ntawm cov txheej ntawd, thiab tom qab ntawd qhov kev sib txuas zoo thiab ntseeg tau yog tau lees paub.
