"Sazilast" yog ob qho khoom siv sib khi, uas muaj txiaj ntsig zoo rau lub sijhawm ntev - txog 15 xyoos. Nws tuaj yeem siv rau yuav luag txhua yam khoom siv hauv tsev. Feem ntau siv rau kev sib khi pob qij txha ntawm lub ru tsev, pob qij txha ntawm phab ntsa thiab qab nthab. Lub sijhawm yuav tsum tau ua kom ruaj khov ntawm cov tshuaj yog ob hnub.

Peculiarities

Sazilast sealant yog thoob ntiaj teb thiab muaj cov yam ntxwv zoo tshaj plaws.

Qhov tshwj xeeb ntawm cov txheej tiv thaiv no yog tias nws tuaj yeem siv rau qhov chaw ntub.

Cov yam ntxwv tseem ceeb yog raws li hauv qab no:

• muaj cov pa tsawg thiab huab cua nruj;
• daim ntawv thov ntawm qhov kub qis yog ua tau;
• cov khoom yog tiv taus diffusion cuam tshuam;
• sib cuam tshuam zoo heev nrog cov ntaub ntawv: qhob, txhuas, ntoo, polyvinyl chloride, cib thiab ntuj pob zeb;
• sib raug zoo nrog cov xim;
• daim ntawv thov rau saum npoo tau tso cai nrog kev tso cai deformation tus nqi tsawg kawg 15%.

Ntau yam

Muaj ntau yam ntim ntim ntim khoom. Qhov nrov tshaj plaws yog cov thoob yas hnyav 15 kg.

Nyob ntawm hom kev thov, 2 pab pawg yog qhov txawv:

1. rau kev teeb tsa hauv paus;
2. rau kev kho vaj tsev.

Txhawm rau kho lub hauv paus, siv "Sazilast" -51, 52 thiab 53. Lawv tau ua los ntawm ob qho kev sib xyaw ua ke, uas yog cov tawv tawv raws li polyurethane prepolymer thiab cov hauv paus muab tshuaj raws polyol.

Tiv taus ultraviolet hluav taws xob / kev sib xyaw 51 thiab 52 /, yog li nws tau pom zoo rau siv rau kev ua haujlwm ru tsev. Thaum ua hauv qhov chaw nyuaj-mus txog qhov chaw, muaj pes tsawg leeg-52 feem ntau yog siv, vim nws muaj cov dej sib xws ntau dua. Rau kev ua haujlwm nrog cov av noo siab, qhov kev xaiv zoo tshaj plaws yog lub foob 53, vim nws tshwj xeeb tshaj yog tiv taus kom raug dej mus ntev.

Txhua lub sealants qhia cov khoom tiv thaiv zoo, lawv ntseeg tau tiv thaiv qhov cuam tshuam ntawm:

• dej;
• cov kua qaub;
• alkalis.

Sazilast -11, 21, 22, 24 thiab 25 tau siv los kho lub ntsej muag ntawm cov tsev, thaj chaw nyob thiab tsis yog tsuas yog txheej txheej. Ob-thooj polysulfide ntsaws ruaj ruaj hom 21, 22 thiab 24 tsis yog npaj rau kev siv nyob. Sealant No. 25 yog polyurethane-based sealant tus yam ntxwv nrawm rau kev siv, vim nws tsis nyob ntawm qhov ntsuas ntawm kev sib koom ua ke thiab qhov ntsuas kub sab nraud ntawm ib puag ncig. Nws kuj tseem tuaj yeem pleev xim nrog cov xim thiab ntau yam tshuaj.

Nws yog siv rau cov dav hlau uas muaj qhov nkhaus ntawm qhov nce txog 25%, nrog rau cov ntsaws ruaj ruaj 22 thiab 24. Cov cim tshwj xeeb ntawm cov ntawv foob 25 tau tshwm sim hauv qhov muaj peev xwm siv li 50% rau qhov tsis xwm yeem. Txhua hom "Sazilast" yog qhov ua tau zoo thiab tiv taus qhov kub tshaj.

Cov khoom muaj daim ntawv pov thawj zoo thoob ntiaj teb, uas ua rau nws muaj xwm txheej thiab lav tau qhov xav tau zoo.

Kev pom zoo

Txhawm rau thov lub foob thaum lub sijhawm ua haujlwm kho, cov cuab yeej hauv qab no xav tau:

1. kev xyaum qis nrog lub duav txuas;
2. spatulas;
3. daim npog qhov ncauj.

Nws yog ib qho tseem ceeb rau kev ua haujlwm kom nyab xeeb kom huv huv ntawm cov qauv. Cov txheej tiv thaiv tau siv rau qhov chaw qhuav lossis ntub. Rau qhov zoo nkauj thiab zoo nkauj zoo nkauj ntawm qhov sib koom ua ke nthuav dav, daim kab xev nplaum tau lo rau ntawm cov npoo ntawm cov khoom tiav.

Tsim nyog los siv rau yam:

1. txoj cai proportions;
2. kub tswj.

Koj yuav tsum tau ua raws cov lus pom zoo no: tsis txhob siv cov tawv tawv hnyav. Txwv tsis pub, txheej txheej tiv thaiv yuav tawv tawv sai, uas yuav ua rau cov qauv tsis muaj zog txaus. Yog tias tsis muaj cov tawv tawv txaus, tom qab ntawv muaj cov nplaum sib xws uas tsis ua tau raws li qhov xav tau.

Thaum ua ntawv thov tiv thaiv ib feem tiv thaiv foob 11, nws tsis raug tso cai rau txheej saum npoo nrog cov dej noo ntau dua 90%, nrog rau nws sib cuag nrog dej. Qhov ntxiv ntawm cov kuab tshuaj yog txwv tsis pub nruj, vim cov yam ntxwv ntawm cov sib xyaw yuav hloov pauv, yam tsis muaj kev txhim kho txhim khu kev qha yuav tsis yooj yim sua. Rau kev sib xyaw 51, 52 thiab 53, nws raug nquahu kom siv cov khoom siv rau saum npoo ntawm qhov kub ib puag ncig ntawm -15 txog + 40 degrees C. Cov txheej yuav tsum tsawg dua 3 hli; yog tias qhov sib koom ua ke dav dua 40 mm, tom qab ntawd thaj chaw yuav tsum tau muab ntim rau hauv ob txoj hauv kev. Ua ntawv thov rau cov tshuaj nyob ib ncig ntawm cov npoo, tom qab ntawd hliv hla qhov sib koom tes.

Kev nyab xeeb engineering

Nws yog ib qho tseem ceeb heev tsis yog kom ntseeg tau thiab raug ua tiav kev teeb tsa cov pob qij txha deformed, nqaws, tab sis kuj ua raws li kev nyab xeeb xav tau. Txhawm rau ua qhov no, koj yuav tsum ua raws cov cai tau teev tseg. Tsis txhob tso lub foob rau hauv daim tawv nqaij, yog tias qhov no tshwm sim, tom qab ntawd nws yog qhov tsim nyog kom yaug thaj chaw tam sim ntawd nrog dej siv xab npum tov.

Txoj cai yooj yim rau txhua lub tsho tiv thaiv yog tiv thaiv kom tsis txhob ya raws. Rau kev tiv thaiv txheej 21, 22, 24 thiab 25, lub sijhawm lav yog 6 lub hlis ntawm qhov kub ntawm -20 txog +30 degrees C. Cov qauv tiv thaiv 11 kuj tseem khaws cia rau 6 lub hlis, tab sis raug rau qhov kub tsawg kawg +13 degrees C, thaum khaws cia tsis qis dua -20 degrees C khaws nws cov khoom rau 30 hnub.

Ob -tivthaiv polysulfide sealants 51, 52 thiab 53 tau khaws cia ntawm qhov kub ntawm -40 txog +30 degrees C rau 6 lub hlis.

Lub sijhawm

Cov txheej tiv thaiv 21, 22 thiab 23 yog siv tau rau 10 txog 15 xyoos. Nrog txheej tuab ntawm 3 hli thiab kev sib hloov deformation txog li 25% nplaum sib xyaw 21, 22, 24 thiab 25, lub sijhawm txwv los ntawm kev pib ua haujlwm yog 18-19 xyoo.
