Thaum ua tiav kev tsim kho, kev teeb tsa ua haujlwm, cov khoom siv xws li lub foob foob feem ntau siv. Kab lus no yuav tsom mus rau thiokol polysulfide sealants, lawv cov yam ntxwv zoo, yam khoom thiab thaj tsam.

Peculiarities

Lub foob niaj hnub no yog cov khoom siv hauv tsev uas tau siv hauv cov txheej txheem sib khi, pob qij txha thiab lwm yam haujlwm kho.

Txhua lub foob tau muab faib ua ob pawg:

• ib qho khoom siv uas npaj tau siv;
• cov khoom siv sib xyaw uas xav tau kev sib xyaw ua ntej.

Thiokol sealants koom nrog pab pawg ntawm cov khoom siv sib xyaw ua ke. Cov no yog ob, peb qhov kev tsim ua ntu zus.

Nws yog dab tsi?

Polysulfide (thiokol) sealant yog ib yam khoom kim tshaj thiab txhim khu kev qha. Yog tias peb xav txog nws cov yam ntxwv zoo, nws tsim nyog sau cia tias nws lub hauv paus yog kua thiokol, uas nyob hauv nws cov qauv zoo li roj hmab. Polysulfide sealants muaj polymers, plasticizers, fillers, pigments thiab texturing agents.

Hom kev sib xyaw hermetic no tau dhau los ua qhov xav tau vim qee yam khoom thiab qhov zoo

• qib siab ntawm lub zog thiab elasticity;
• ya raws tsis kam;
• qis roj permeability;
• nce qib ntawm kev tiv thaiv rau cov khoom xws li roj av, roj, alkalis, ntxhia acids, cov organic hnyav;

• tiv thaiv UV hluav taws xob thiab lwm yam kev cuam tshuam ib puag ncig;
• lub peev xwm los siv hauv qhov kub thiab txias sib txawv, ntawm -55 txog +35 degrees;
• nplaum zoo heev, tso cai rau siv cov ntawv foob no rau hauv ntau yam lag luam thiab ntawm ntau qhov chaw, suav nrog ntoo, hlau thiab pob zeb ua;
• ua haujlwm ntev (kev pabcuam lub neej ntawm cov khoom siv no ntau dua 20 xyoo);
• cov cim zoo ntawm kev hloov pauv mus tas li.

Cov khoom siv polysulfide muaj ob peb qhov tsis zoo

• Kev tsis sib haum nrog cov khoom yas. Qhov no yog vim qhov tseeb tias cov nplaum muaj cov kuab tshuaj uas muaj qhov tsis zoo ntawm cov khoom yas.
• Tom qab sib tov, cov khoom siv yuav tsum siv sijhawm luv (2-3 teev), txwv tsis pub nws yuav poob tag nrho nws cov khoom.
• Thaum siv lub foob, yuav tsum siv cov khoom tiv thaiv.

Cov khoom siv polysulfide tuaj yeem qhia nws cov khoom 100%. Txawm li cas los xij, rau qhov no koj yuav tsum coj mus rau hauv tus account qee cov lus pom zoo.

"UT-32" thiab "U-30M"

Muaj cov ntaub ntawv uas tau siv hauv kev xyaum ntau dua li lwm yam. Ntawm lawv yog UT-32 polysulfide sealant thiab U-30M.

UT-32 thiokol sealant yog siv rau hermetic sealing ntawm cov qog ntim. Nws feem ntau siv nyob rau hauv cov txheej txheem ntawm kev sib khi cov khoom siv hluav taws xob, cov txuas txuas, ntau yam hlau sib txuas uas ua haujlwm hauv huab cua lossis roj. Qhov no kuj siv rau ntau yam kev tsim qauv uas tsis muaj tooj dag, nyiaj thiab tooj liab sib cuag. Cov ntawv foob no kuj tseem siv dav hauv kev tsim tshuab, kev ya dav hlau, ntsuas qhov ntsuas.

Thiokol cov khoom tau txais txiaj ntsig nrog tus lej ntawm cov khoom, suav nrog:

• siab tsis kam rau deformation;
• nce kev tiv thaiv rau cov teebmeem ntawm cov roj, roj av;
• lub peev xwm los tiv thaiv zoo cuam tshuam los ntawm ultraviolet rays, nrog rau cov pa;
• muaj peev xwm siv cov khoom siv ntawm qhov kub thiab txias sib txawv (ntawm -60 txog +130 degrees).

Xws li kev sib xyaw ua ke yog pab pawg ntawm peb cov khoom siv sib xyaw. UT-32 yog cov tshuaj dawb los yog txho uas tau yaj nrog cov kuab tshuaj. Txhua yam khoom siv tau sib xyaw ua ntej siv. Qhov saum npoo uas yuav siv cov khoom siv hermetic yuav tsum tau ua ntej ntxuav cov hmoov av, av, cov khoom txawv teb chaws. Thaum tshem cov roj thiab cov roj nplaum, cov nplaim degreased (siv roj av). Lub sealant tsuas yog siv rau thaj chaw qhuav ntawm qhov chaw.

Thiokol sealant "U-30M" tau tsim los ntawm cov kua thiokol thiab ua kom sov ntawm qhov kub li ntawm +15 degrees txog 0 . Nws yog siv rau kev ntim cov txheej txheem hlau ruaj khov. Cov kev zam yog tooj dag thiab nyiaj tooj liab. Cov muaj pes tsawg leeg yog siv nyob rau hauv ib puag ncig huab cua thiab qhov kub thiab txias.

Nws tau siv ua ke nrog kua nplaum, uas yog siv los ua cov nplaum nplaum. Cov kua nplaum raug xaiv coj mus rau hauv tus account yam khoom siv hauv paus yog ua los ntawm. Tus nab npawb ntawm txheej uas tau thov rau saum npoo yog nyob ntawm hom kua nplaum xaiv. Raws li txoj cai, cov no yog ob txheej. Lub sij hawm qhuav rau txhua txheej yog los ntawm 30 feeb mus rau 1.5 teev.

Ua ntej pib kev sib khi, cov nplaim raug ntxuav los ntawm hmoov av, av (siv txhuam). Yog tias tsim nyog, degrease saum npoo lossis cov khoom ib tus neeg. Roj av yog qhov tsim nyog rau qhov no. Nws yog qhov zoo dua los nqa cov degreasing hauv thaj chaw me me kom lub ntsej muag tsis muaj sijhawm los txhaws dua. Tom qab degreasing, nws yuav siv sij hawm kom qhuav.

Scope thiab thev naus laus zis ntawm kev thov

Vim nws cov yam ntxwv, thiokol sealant tau siv rau txhua qhov chaw nws tsim nyog los tiv thaiv kev sib cuag nrog ntau yam tshuaj. Cov no yog, raws li txoj cai, chaw muag roj tsheb, chaw nres tsheb, chaw tso roj, chaw tso roj thiab roj nplua nyeem. Cov khoom siv no yog siv los kho cov ru tsev hlau.

Lub foob tau pom muaj daim ntawv thov dav hauv kev tsim cov qhov rai ob-glazed. Nws yog siv los ntim cov pob qij txha, tawg, tawg hauv cov pob zeb, txhim kho cov pob zeb ua haujlwm, qhov uas deformation tsis tshaj 25%.

Yog tias koj yuav siv cov khoom sib xyaw no, koj yuav tsum paub koj tus kheej nrog kev siv thev naus laus zis, uas zoo ib yam rau txhua hom.

Ua ntej thov, koj yuav tsum paub tseeb tias:

• saum npoo tau zoo ntxuav cov khoom qub qub;
• countersinking ntawm mounting qhov tau ua;
• cov cheeb tsam uas tsis siv cov khoom siv tau muab lo nrog daim kab xev nplaum;
• cov khoom siv tau npaj rau siv.

Yog tias txhua yam npaj txhij, koj tuaj yeem pib txheej txheem ntim khoom. Txhawm rau ua tiav cov txiaj ntsig ua haujlwm tau zoo, koj yuav tsum xav txog txhua qhov kev pom zoo tseem ceeb.
