Sealants yog cov khoom siv los kaw cov pob qij txha hauv lub tsev lossis lwm yam qauv. Lawv tiv thaiv qhov chaw los ntawm ya raws, chav, roj, pa phem. Sealants yog siv rau kev tsim kho thiab kho, nrog rau hauv lub neej txhua hnub rau ntau yam kev xav tau. Lawv yog qhov yooj yim tshaj plaws los khi txhua qhov thiab cov kab nrib pleb. Txhawm rau xaiv qhov zoo ntawm sealant, koj yuav tsum nkag siab txog lawv ntau yam thiab thaj tsam ntawm txhua tus.
Dab tsi
Txhua cov sealants tau muab faib ua cov chav kawm raws li cov yam ntxwv tshwj xeeb, ntawm cov khoom siv tshuaj, lub hom phiaj thiab qib ntawm elasticity. Lawv tso cai rau koj los qhia txog qhov yuav tsum tau siv ib lossis lwm hom sealant hauv ntau qhov xwm txheej. Kev tsim sealants muab faib ua:
- thiokol;
- polyurethane;
- acrylic;
- silicone;
- butyl.
Thiokol sealants
Cov no yog polysulfide sealants muajraws li thiokol. Hom no suav hais tias yog qhov ruaj khov tshaj plaws, elastic thiab ruaj khov. Lawv lub sijhawm siv tau yog kwv yees li 30 xyoo. Dav siv nyob rau hauv mechanical engineering, lub teeb kev lag luam, shipbuilding, xov tooj cua engineering. Vim nws lub zog thiab kev ntseeg siab, cov khoom siv no suav hais tias yog qhov zoo tshaj plaws sealant rau lub log tsev. Yog li ntawd, lawv tau nce siv hauv kev tsim vaj tsev. Thiokol sealants raws li lawv muaj pes tsawg leeg yog muab faib ua ob- thiab peb-tivthaiv. Cov muaj pes tsawg leeg yog kneaded tam sim ntawd ua ntej siv thiab tag nrho vulcanized nyob rau hauv 10 hnub.
Sealants ntawm hom no zoo heev rau kev sib khi ntau yam duab, yuav luag tsis ntsws thiab tsis tawm cov kuab tshuaj. Kev tsim cov sealants uas muaj thiokol tuaj yeem siv dawb hauv txhua qhov huab cua. Lawv muaj cov qib siab elasticity, roj-tiv taus, muaj peev xwm tiv taus cov khoom hnyav thiab hluav taws xob ultraviolet. Muaj nyob rau hauv dub thiab grey.
YPolyurethane sealants
Lawv yog siv los tsim cov vaj huam sib luag loj, nrog rau cov façade sealants hauv kev tsim cov vaj tse loj. Qhov nrov tshaj plaws sealant tuam txhab "TechnoNIKOL". Nws yog siv rau kev sib txuas thiab sealing ntau qhov chaw los ntawm:
- hlau;
- pob zeb;
- varnished ntawv;
- ceramics;
- pob zeb;
- tsob ntoo;
Y- PVC.
TechnoNIKOL polyurethane sealant yog sealing, nplaum thiab elastic khoom uas ruaj khov mus tas lithawj qhov sib xws. Lub ntsiab ntawm daim ntawv thov ntawm polyurethane sealants yog lub sealing ntawm interpanel pob qij txha nyob rau hauv tej yam kev mob ntawm muaj zog deformation load. Sealant yog tsim rau cov cav cabins, nrog rau tag nrho cov pob qij txha raug kev co los yog deformation. Ua tsaug rau nws lub peev xwm sib txuas tau zoo, nws tuaj yeem tiv taus txawm tias av qeeg txog li 5.
Tsis tas li, TechnoNIKOL polyurethane sealants paub txog lawv cov kev tiv thaiv rau Frost, acids, corrosion, ultraviolet, tsis muaj zog alkaline thiab saline daws. Lawv tuaj yeem siv rau qhov chaw ntub dej thiab pleev xim.
Acrylic Sealants
Lawv nrov vim lawv pheej yig. Acrylic sealant yog siv tshwj xeeb rau sab hauv, kev ua haujlwm hauv tsev, vim nws yog cov yas ntau dua elastic. Nws tsis tuaj yeem rov tsim nws daim ntawv tom qab raug kev cuam tshuam rau txhua yam.
Siv acrylic sealants los kaw qhov thiab qhov uas tsis muaj kev vibration. Piv txwv li, nws tuaj yeem yog qhov chaw me me ntawm lub qhov rais sill thiab lub qhov rais, hauv pem teb boards, lub qhov rooj ncej thiab ib feem ntawm phab ntsa. Acrylic yog zoo diluted nrog dej, yog li nws yog yooj yim mus thov nws nyob rau hauv nqaim qhib. Tsis tas li ntawd, tsis zoo li lwm lub tsev sealants, acrylic tuaj yeem ntxuav tau yooj yim, qhov tseem ceeb yog kom muaj sij hawm ua qhov no ua ntej nws hardens.
Lawv tsis muaj cov tshuaj txaus ntshai thiab tshuaj lom, lawv yooj yim pleev xim thiab plaster. Sealant yog thov siv rab phom tshwj xeeb lossis los ntawm ib lub raj. Qhov kawg hardening ntawm cov khoom tshwm sim tom qab 24 teev. Ntawm qhov tsis txaus ntseeg tuaj yeem txheeb xyuas qhov tsis muaj zog, tsis muaj peev xwm tiv taus qhov kub thiab txias.
YSilicon Sealants
Paub tias yog qhov feem pua ntawm kev faib khoom hauv kev kho thiab kev tsim kho. Haum rau industrial thiab domestic siv. Silicone sealants yog siv rau kev ua haujlwm sab nraum zoov (kev sib khi ntawm lub tsev, chimneys, cov kav dej thiab cov kav dej), nrog rau kev ua haujlwm sab hauv (kev teeb tsa cov iav, ceramics, ob chav glazed qhov rais).
Cov txiaj ntsig hauv qab no yog cov yam ntxwv ntawm pawg tshuaj no:
- Y UV resistant;
- muaj peev xwm tiv taus qhov kub thiab txias;
- qib siab ntawm adhesion;
- resistance rau ib puag ncig nruj;
- durability.
Silicone sealants, txawm tias lawv tsis pleev xim, muaj lawv tus kheej palette ntau yam. Raws li lawv cov qauv, lawv tau muab faib ua ib- thiab ob-cov khoom. Cov yav tas yog siv nyob rau hauv lub teb ntawm industrial ntau lawm. Single-component sealants muab faib ua nruab nrab thiab acidic sealants. Cov kua qaub muaj zog ntau dua, tab sis thaum lub sij hawm vulcanization, acetic acid raug tso tawm los ntawm lawv, uas ua rau muaj ntxhiab tsw ntxhiab thiab ua rau tsis yooj yim thaum ua haujlwm. Vim tias muaj cov kua qaub, lawv yuav tsum tsis txhob siv cov khoom siv hlau thiab cov cement. Txwv tsis pub, muaj kev pheej hmoo loj ntawm corrosion. Tab sis kua qaub silicone sealants muaj qhov zoo dua - qhov no yog lawv tus nqi tsim nyog.
Butylsealants
Lawv yog cov khoom siv thermoplastic raws li cov roj hmab hluavtaws (polyisobutylene). Nws tiv taus cov tshuaj dawb, alkalis, acids thiab ntau lwm yam tshuaj. Cov qauv ntawm vulcanized sealant zoo ib yam li roj hmab.
Ntawm qhov zoo ntawm lub tsev sealants ua los ntawm polyisobutylene, ib qho tuaj yeem tawm nws txoj kev nyab xeeb rau tib neeg kev noj qab haus huv, qib siab ntawm adhesion rau iav, nrog rau txhuas thiab hlau, cov qauv galvanized. Cov yam tseem ceeb yog elasticity, plasticity, durability thiab tus nqi qis ntawm sealant. Nws qhov chaw tseem ceeb ntawm kev siv yog kev tsim cov qhov rais ob chav glazed.
Hauv kev lag luam hauv tsev, butyl sealant feem ntau siv los kaw cov kab nrib pleb, qhov khoob thiab cov pob qij txha ntawm cov qauv. Lawv muab cov kab hluav taws kub-insulating nrog nws, kaw cov cua ducts, cua txias tshuab. Lub txee lub neej ntawm cov sealants no yog hais txog 20 xyoo. Ntawm qhov tsis txaus, tsuas yog xim dub ntawm cov khoom thiab qhov nqaim tuaj yeem paub qhov txawv.
Kev xaiv cov ntaub ntawv rau kev sib khi
Kho lub tsev vaj huam sib luag, thiab tshwj xeeb tshaj yog nws txoj haujlwm tiav, yuav tsis ua haujlwm zoo yam tsis muaj kev sib khi chav dej, qhov rais, qhov rooj thiab ntau yam seams. Yog li ntawd, nws yog ib qho tseem ceeb heev uas yuav tau xaiv cov khoom siv hauv tsev zoo nrog lub neej ua haujlwm ntev, ua tib zoo saib xyuas lub teb chaws ntawm lub hauv paus chiv keeb, lub tuam txhab, hom polymerization (acidic los yog nruab nrab), nrog rau cov Scope. Nws yog tsis yooj yim sua kom tsis pom lub sij hawm tsim zaj duab xis ntawm lub sealant, lub sij hawm uas nws yuav tsum tau qhuav,Kev hloov pauv qhov kub thiab txias, thiab tsis yog thaum siv cov khoom siv xwb, tab sis kuj tseem nyob rau lub sijhawm ua haujlwm tag nrho.
