Txij li thaum lub sealant yog kuab tom qab tua shrinkage nws tsis, thiaj li tsis muaj tej kab nrib pleb tshwm sim, thiab lub pob qij txha muaj kev tiv thaiv los ntawm noo noo.

Cov khoom muaj zoo heev adhesion nrog luag tag nrho cov kev tsim kho cov ntaub ntawv: cib, hlau, ntoo, ua vaj tse, plaster thiab lwm tus neeg.

Ntawm cov tseem ceeb tshaj plaws yam ntxwv uas muaj Thiokol sealant, siab kuj mus raug nyiaj:

1. Thaum tshav kub kub.
2. Shrinkage deformation.
3. Tsis tshua muaj kub.
4. UV.
5. Infrared tawg.

Qhov no ua rau nws tau siv cov ntaub ntawv uas nyob rau hauv tej climatic cheeb tsam ntawm lub CIS thiab Russia.

Yuav tsum muaj rau sealants

Txawm li cas los ntawm qhov chaw ntawm lub sib koom tes, sib khi cov ntaub ntawv uas yuav tsum tau siv:

1. Khaws tag nrho nws cov yam ntxwv nyob rau hauv tag nrho cov huab cua puag.
2. Kom lawv lub zog rau ib ntev lub sij hawm.

Txawm li cas los, yog hais tias tus ambient kub hauv qab no yog zero, lub hardening txheej txheem slows thiab tag tsis nyob -40 ° C.

Kom ceev li lub vulcanization yog ntim nqaws, lawv yuav tsum tau sov so li. Cov txheej txheem yog ua kom tiav rau xwb 12-16 teev yog hais tias tus cua kub kub yog 80 degrees, thiab 50 degrees thaum hardening yog tiav tom qab 26-36 teev.

Ua ntej thov kev lub Sealer los npaj qhov chaw - ntxuav nws los ntawm te, plua tshauv, av. Thiokol sealant yog thov tsuas yog nyob rau qhuav chaw.

Manufacturers lav ib tug tsawg kawg nkaus txoj sia luv ntawm cov khoom - los ntawm 10 xyoo thiab saum toj no: nws nyob rau hauv lub Aggressiveness ntawm surrounding chaw.

Ib qho tseem ceeb kom meej: thaum lub sij hawm npaj ntawm mastic yog txwv tsis pub siv tej yam kuab tshuaj.

Cia thiab tsheb thauj mus los

Muag khoom sealing mastic nyob rau hauv hlau thawv nyob rau hauv luam duab los qhia drums los yog lwm yam ntim. Lub ntsiab yuav tsum tau rau nws - nws tau ua kev sib khi thiab ntau lub qhov ncauj. Pre-muab tshuaj txhuam yog ntim rau hauv ib lub hnab ntawm polyethylene thiab ces muab tso rau hauv ib tug tare thawv. Nws yuag - 30 los yog 75 kg. Cia cov ntaub ntawv uas yuav ua tau nyob hauv tsev, uas yog zoo ventilated, los yog nyob rau hauv ib tug toj los tiv thaiv los ntawm ncaj qha tshav ntuj thiab tiv thaiv kom txhob ingress ntawm dej.

Yog hais tias mastic thiokol muab tawm sab nraud, qhov kub thiab txias ntawm lub nce saum toj no 30 ^{° C} los yog poob qab ^-20 ° C, cov khoom yuav tsum tau muaj kev tiv thaiv los yog yuav tsum tau tsiv mus rau ib tug cia chav tsev yoog.

Sealant yuav thauj nyob rau hauv tej yam kev thauj, vim hais tias nws yog uas tsis yog-tej substance.

kev ruaj ntseg ntsuas

Txawm hais tias sealant Thiokol tsis yog ib tug txaus ntshai yeeb tshuaj, tseem yuav tsum ua raws ib tug ob peb ceev faj:

1. Tau mus ua hauj lwm, tsuas yog hnav roj hmab hnab looj tes.
2. Tsis txhob sib chwv nrog daim tawv nqaij saum npoo av.

Yog hais tias cov ntaub ntawv uas yog nyob rau hauv raug daim tawv nqaij, nws yuav tsum tau muab tshem tawm siv dej cawv. Ces koj yuav tsum ntxuav cov nplaim ntawm daim tawv nqaij nrog xab npum thiab dej.
