tswvyim
Barite plasters yog cov cement-xuab zeb qhuav. Tsis zoo li cov plaster zoo tib yam, lawv muaj barium sulfate concentrate. Nws yog qhov muab tub lim no yog lub luag haujlwm rau cov khoom tshwj xeeb ntawm cov khoom siv. Cov cement qib siab ua raws li kev sib khi, thiab tseem muaj ntau yam plasticizers uas yog lub luag haujlwm rau cov yas ntawm cov tshuaj.
Cov xuab zeb barite suav nrog hauv lawv cov muaj pes tsawg leeg hloov pauv siv cov ntawv txhuas. Nws yog ib txoj hauv kev pheej yig dua los tiv thaiv gamma hluav taws xob, tab sis tsis muaj txiaj ntsig tsawg dua.
Daim ntawv thov
Barite plaster yuav tsum tau siv rau ntawm phab ntsa. Txhawm rau ua qhov no, koj yuav tsum muaj kev txawj ntse. Hauv txoj cai, kev siv tshuab zoo ib yam li kev ua haujlwmnrog cov kev daws teeb meem. Txawm li cas los xij, tseem muaj qee qhov nuances:
- Kev npaj nto. Cov txheej txheem qub tau raug ntaus tawm, cov phab ntsa yog primed, thiab tsuas yog tom qab lawv qhuav tag, barite plaster yog siv.
- Daim ntawv thov thev naus laus zis yog qhov zoo li yog tias nws cov txheej txheem muaj qhov tuab ntawm ntau dua 30 hli, ces cov mesh tshwj xeeb yuav tsum tau ntim rau ntawm phab ntsa. Nws yuav tsim kom muaj zog thiab txhim khu kev qha kev sib txuas ntawm cov mortar thiab lub hauv paus.
- Qhov sib tov yog siv rau hauv ob peb txheej. Lub thickness ntawm txhua ntawm lawv yuav tsum tsis txhob ntau tshaj 10-15 mm. Nws yog ib qho tsim nyog los tiv thaiv lub sijhawm ntawm lawv ziab, qee zaum nws tuaj yeem ncav cuag 3 hnub.
- Txhua txheej yog kho nrog primers.

- Kev siv plaster rau 1 sq. m yog kwv yees li 20 kg, yog tias txheej txheej tsis tuab dua 10 hli.
Scope of application
Feem ntau hom plaster no yog siv nyob rau hauv cov chav uas kev ntsuam xyuas tau ua los ntawm cov khoom siv tshwj xeeb, uas yog qhov chaw ntawm gamma hluav taws xob. Cov no yog cov chaw kho mob, tsev kho mob, chav X-ray, nrog rau cov chaw lag luam koom nrog qee yam kev tshawb fawb.
Yuav kom txwv kev nkag mus ntawm hluav taws xob, cov phab ntsa yog kab nrog cov ntawv txhuas, txawm li cas los xijtxoj kev no yog kim heev. Lwm txoj kev xaiv yog siv barite plaster rau saum npoo nrog ib txheej ntawm yam tsawg 25 hli. Ib txheej ntawm cov tuab no muaj cov khoom siv lead ua thiab yog qhov tsim nyog hloov pauv rau nws. Txij li cov nplooj ntawv ntawm cov hlau no yog cov khoom lag luam tsis tshua muaj, nws siv tsis ntau heev piv rau plaster.

Nyob ntawm qhov tuab ntawm cov txheej txheej, ib qho kev txhawb nqa mesh yog khoom, uas ua kom ntseeg tau thiab muaj zog adhesion ntawm plaster mortar rau saum npoo.
Barite plasters: txoj cai ua haujlwm
- Cov qhuav sib tov yog diluted nrog dej hauv qhov sib piv ntawm 1 kg - 200 ml. Cov kua yuav tsum nyob rau ntawm chav tsev kub: kwv yees li 20 0C. Koj tuaj yeem sib tovmanually los yog siv cov khoom siv tshwj xeeb. Cov tshuaj tiav yuav tsum muaj qhov sib xws. Tom qab sib tov, nws yog ib qho tsim nyog los tiv thaiv 5-8 feeb thiab tsuas yog tom qab ntawd koj tuaj yeem pib thov ncaj qha.
