Txhawm rau kom ntseeg tau ruaj khov rau cov nqaws thiab qhov khoob uas tau tsim thaum tsim ntau yam kev tsim kho lossis kho ua haujlwm ntawm cov chaw, cov kws ua haujlwm siv cov nplaum uas tsis ua kom tawv tawv. Qhov no yog qhov tseeb tshwj xeeb hauv kev tsim vaj tsev ntiag tug thiab vaj huam sib luag loj nrog qhov sib koom ua ke ntawm 20 txog 35 hli . Thiab tseem muaj qhov sib xyaw no feem ntau ua raws li lub foob, uas ua rau qhib qhov nruab nrab ntawm cov phab ntsa uas muaj lub nra thiab lub qhov rooj lossis qhov rooj.

Peculiarities

Sealing mastic yog cov khoom lag luam nrov heev hauv kev tsim kho kev lag luam. Nws ua raws kom zoo rau yuav luag txhua qhov chaw, nws tsis muaj dej txaus vim qhov tseeb tias cov nplaum raws cov bitumen tsis muaj qhov hws, yog li cov dej yuav tsis pom qhov twg.

Txhua qhov xwm txheej rau kev sib xyaw no tau teev tseg hauv GOST . Cov khoom tuaj yeem tiv taus cov dej mus txog 10 feeb, muab tias lub siab nyob hauv 0.03 MPa. Cov npav thauj mus los yuav tsum muaj.

Ntawm cov yam ntxwv ntawm cov muaj pes tsawg leeg, ib tus tuaj yeem nco qhov tseeb tias mastic tsis xav tau daim ntawv thov ntawm kev siv zog tshwj xeeb thaum thov nws ., thiab txheej nws tus kheej yog ruaj thiab muaj zog. Thaum ua ntawv thov raug, tsis pom cov nqaws nyob ntawm qhov chaw. Nws tuaj yeem siv ob qho tib si hauv kev tsim kho tshiab thiab kho dua tshiab ntawm lub ru tsev qub.

Dhau li, nws muaj peev xwm ua tiav qhov xav tau ntau yam xim ntawm txheej . Txhawm rau ua qhov no, koj tsuas yog xav tau ntxiv cov xim tshwj xeeb rau cov muaj pes tsawg leeg. Xws li mastic tau siv txawm tias ua haujlwm nrog lub ru tsev ntawm cov duab sib txuam nrog cov khoom zoo nkauj.

Rau kev txhawb nqa cov mastic, nws raug tso cai siv tsuas yog fiberglass. Vim qhov no, nws dhau los ua qhov muaj zog thiab ruaj khov.

Yog tias peb piv cov dej tsis sib haum nrog mastic nrog cov khoom nqaim-yob, tom qab cov lus xaus hauv qab no qhia lawv tus kheej

• Qhov muaj pes tsawg leeg tuaj yeem thov nrog cov menyuam lossis txhuam, nrog rau tshuaj tsuag tshwj xeeb. Qhov no tso cai rau koj ua haujlwm nrog cov duab sib txawv ntawm cov khoom.
• Kuv yuav tsum hais tias cov muaj pes tsawg leeg yog pheej yig. Qhov no yuav pab txuag nyiaj thaum tsim kho thiab kho dua tshiab.
• Mastic yog qhov sib zog ntau dua li cov khoom siv nqaim-web, thaum nws xav tau tsawg kawg 2 zaug tsawg dua.

Muaj pes tsawg leeg

Muaj ntau hom kev sib khi mastic. Ntawm lawv yog bitumen-polymer, ntxiv rau cais bitumen thiab polymer . Nws nyob ntawm qhov tseem ceeb ntawm cov khoom siv sib xyaw. Ntxiv rau nws, cov kuab tshuaj thiab lwm yam ntxiv tau ntxiv rau ntawm no, ua rau muaj kev sib xyaw zoo tshaj plaws rau koom nrog lub qab nthab.

Hermobutyl mastic tuaj yeem yog ib qho lossis ob qho khoom siv . Lub sijhawm no yuav tsum raug coj mus rau hauv tus account thaum xaiv.

Lub hauv paus ntawm ib qho kev sib xyaw ua ke yog cov kuab tshuaj. Txhawm rau siv nws, tsis tas yuav npaj ua haujlwm. Cov khoom siv tawv tawv tom qab ua tiav cov tshuaj hnyav. Koj tuaj yeem khaws cov mastic li 3 lub hlis.

Hauv ob qhov khoom siv sib xyaw, ntxiv lwm cov khoom sib xyaw ua ke, vim tias cov paj ntoo tuaj yeem khaws cia ntau dua 1 xyoos. Ntawm cov txiaj ntsig tseem ceeb yog kev muaj peev xwm ntxiv lwm cov qauv hauv cov txheej txheem ua haujlwm.

Cov ntawv thov

Thaj chaw ntawm daim ntawv thov kev sib khi mastics yog qhov dav heev. Yog tias peb tham txog cov lus qhia tseem ceeb, ua ntej tshaj plaws, ib tus yuav tsum tau sau lub npe ntawm kev sib khi thaum lub sijhawm tsim kho . Tsis tas li ntawd, qhov no siv tsis yog rau kev tsim vaj tsev nkaus xwb, tabsis tseem siv rau kev teeb tsa ntawm txoj kev. Thiab tseem muaj qhov sib xyaw tau siv hauv kev tsim cov choj txhawm rau kaw cov kav dej thiab cov kab hluav taws xob.

Kev siv mastic pab tiv thaiv kev tsim cov xeb saum npoo vim raug rau ultraviolet rays thiab huab cua nag lossis daus. Cov ntaub ntawv no muaj feem cuam tshuam rau kev tsim cov lej . Tsis tas li ntawd, kev tsim muaj pes tsawg yog tsim nyog rau kev ua haujlwm vov tsev.

Cov cai thov

Thaum ua haujlwm nrog kev ua kom tsis muaj zog ua mastic, yuav tsum tau ua raws li ntau txoj cai. Qhov no yuav tso cai rau koj kom ua tiav cov txiaj ntsig xav tau thiab ruaj ntseg koj cov haujlwm.

• Qhov saum npoo yuav tsum tau thov yuav tsum tau ntxuav thiab qhuav . Kev tsim cov cement thiab cov khib nyiab raug tshem tawm, uas ua rau cov pob qij txha txhaws. Lub hauv paus nws tus kheej yuav tsum tau pleev xim ua ntej, vim tias cov yeeb yaj kiab yuav tshwm rau ntawm nws, tiv thaiv kev sib xyaw los ntawm kev nqus dej ntawm cov yas.
• Yog tias peb tab tom tham txog cov av qhuav, tom qab ntawd cov tuab tuab ntawm lub hauv paus tsis muaj dej, nteg ntawm 2 meters, yuav tsum yog 2 hli . Yog tias qhov ntsuas thawj zaug nce ntxiv thiab yuav qhia nyob rau qib siab txog 5 metres, yuav tsum tau siv cov nplaum ua ntej hauv 4 txheej, tag nrho cov tuab uas yuav tsum yog yam tsawg 4 hli.
• Kev tsim kho cov haujlwm yuav tsum tsis txhob ua thaum lub sijhawm nag lossis daus, nrog rau tam sim ntawd tom qab nws, thaum qhov chaw tseem ntub . Hauv qhov xwm txheej thaum siv bitumen kub, koj yuav tsum saib xyuas cov khaub ncaws uas tiv thaiv lub cev los ntawm qhov ua tau los ntawm cov tshuaj yaj yeeb yaj kiab. Ib qho ntxiv, nws tsim nyog siv lub tshuab nqus pa los tiv thaiv kab mob ua pa.
• Kev sib xyaw ua ke raws li bitumen thiab cov kuab tshuaj yog cov nplaim taws, yog li lawv xav tau kev saib xyuas tshwj xeeb thaum ua haujlwm nrog lawv . Txoj cai kev nyab xeeb sau tseg tsis txhob haus luam yeeb nyob ib puag ncig ntawm qhov chaw uas ua haujlwm tiv thaiv dej, thiab tseem yuav tsum zam kev siv nplaim taws qhib. Nws muaj kev nyab xeeb dua los ua haujlwm hauv cov iav tiv thaiv thiab hnab looj tes tiv thaiv kab mob.

Sealing mastics tau thov ntawm qhov kub tsis qis dua -20 degrees. Qhov muaj pes tsawg leeg nws tus kheej yuav tsum nyob ntawm chav sov. Qhov chaw tso hluav taws xob tuaj yeem siv tau yog tias tsim nyog.
