Kev faib tawm tseem ceeb ntawm cov ntawv foob yog txiav txim siab sib cais raws lub hauv paus tseem ceeb hauv kev sib xyaw

Polyurethane foob , uas muaj lub zog siab thiab ua haujlwm ntev, yog li nws feem ntau siv hauv kev lag luam. Tab sis rau tsev neeg lub hom phiaj, nws yog qhov tsim nyog yog tias koj xav tau nrawm thiab tsim cov gaskets, ntxiv rau kaw cov nqaws ntawm lub tsheb. Txawm li cas los xij, nws cov nplaum ntau ntxiv rau lwm cov ntaub ntawv kuj tseem muaj qhov poob qis - hauv nws cov khoom nws zoo ib yam li cov kua nplaum polyurethane, yog li nws tuav txhua yam nruj, yog li cov sealant tsis haum rau txav tau thiab sib tsoo ntawm cov txheej txheem.

Ib txoj hlua khi nrog polyurethane sealant tsis ntshai ya raws lossis hnub ci, yog li cov kua nplaum feem ntau siv rau kev ua haujlwm sab nraum zoov, tshwj xeeb tshaj yog thaum kho lub ru tsev ntawm cov tsev. Tsis tas li, polyurethane sealant nquag tawm tsam cov tshuaj muaj zog, yog li thaum kho lub tsheb tom qab siv nws, koj tuaj yeem kho txhua yam los ntawm saum toj no nrog kev tiv thaiv lossis tiv thaiv xeb txheej. Nrog rau qhov ua tau zoo tshaj plaws thiab tiv taus kom deformation, cov nplaum no kuj tseem zoo rau kev kho vaj tsev.

Qhov tsis zoo ntawm polyurethane sib txuas yog lawv cov tshuaj lom ntau thiab tsis hnov tsw ntxhiab tsw ntxhiab thaum lub sijhawm ua haujlwm, uas yog vim li cas lub foob foob tsis haum rau siv sab hauv. Yog lawm, thiab ntawm txoj kev nrog nws, koj yuav tsum tau ua raws txhua txoj cai kev nyab xeeb, thiab muab cov kua nplaum tso rau hauv qhov tiv thaiv thiab npog ntsej muag.

Anaerobic foob - tus neeg sawv cev muaj zog txaus siv rau kev sib khi thiab tsim cov gaskets hauv ntu ntu ntawm ob lub kav dej thiab ntau yam txheej txheem, piv txwv li, flanges. Lub peculiarity ntawm anaerobic sib txuas yog tias lawv sib zog, qhov tseeb, tsis muaj kev sib cuag nrog huab cua, tab sis dhau los ntawm polymerization hauv kev sib cuag nrog hlau. Txoj kev ziab no kom ntseeg tau tias muaj kev ruaj khov thiab muaj zog.

Ua ntej yuav ib lub foob, koj yuav tsum nkag siab meej txog cov khoom uas nws yuav siv, vim tias nyob ntawm qhov no, koj yuav xav tau cov cuab yeej sib txawv qib ntawm lub zog. Yog li, cov kua nplaum uas tsis muaj zog nrog qib qis ntawm lub zog yuav tsum tau siv rau cov pob qij txha uas nyob hauv qhov tsis tu ncua, raug rau qhov hnyav lossis tshem tawm ntau zaus.

Qhov nruab nrab lub zog nplaum yog xav tau rau cov pob qij txha uas tsis tshua muaj raug tshem tawm thiab feem ntau yog so, piv txwv li, cov khoom hauv tsheb. Cov ntaub nplaum uas muaj zog tshaj plaws yuav tsum tsuas yog siv rau qhov ruaj khov thiab txuas txuas, vim nws yuav luag tsis tuaj yeem cais lawv tom qab.

Ntawm qhov pom tau zoo ntawm anaerobic sealants, ib tus tuaj yeem tawm tsis tiv taus qhov kub lossis tiv tshav kub, txog li 100-150 ° С rau qhov nruab nrab cov kua nplaum hauv kab no thiab nce mus txog 175 ° С hauv qee yam khoom. Ntawm lwm yam, cov ntawv foob no tiv taus cov tshuaj nyuaj xws li roj av, roj cav lossis ethylene glycol. Vim yog qhov xwm txheej no, cov tshuaj anaerobic tau siv los kho ob lub tsheb thiab, piv txwv li, teeb tsa lub tshuab hluav taws xob hauv tsev lossis chav rhaub dej kub.

Anaerobic sealant yog kev lag luam zoo heev, tab sis nws tseem tsim nyog yuav nws nrog cov khoom lag luam yam tsawg. Nws ua tau zoo rau saum npoo tsuas yog tias nws tau muab faib sib npaug thoob plaws txhua qhov chaw nqaws. Yog tias cov kav dej raug kho los ntawm sab hauv, nws tsis tau pom meej tam sim ntawd xav tau ntau npaum li cas cov sealant uas yuav tsum tau muab khi. Yog tias qhov sib txawv tsis tau ua tiav lossis cov foob tau thov hauv ob peb theem, nws yuav tawv tsis sib luag. Hauv qhov xwm txheej zoo li no, nws tsis tas yuav suav nrog qhov ua tau ntev ntawm kev sib txuas, vim tias cov nqaws tuaj yeem sib tsoo hauv qhov cuam tshuam ntawm kev co.

Cov qib siab ntawm cov nplaum ntawm anaerobic sealant rau cov hlau saum npoo kuj tseem muaj qhov tsis zoo - thaum tshem tawm lossis hloov kev sib txuas, qee zaum koj yuav tsum siv cov cuab yeej tshwj xeeb los cais cov ntsiab lus los ntawm ib leeg. Hauv qee kis, nws tseem yuav tsum tau ua kom sov qhov chaw gluing mus rau qhov kub siab kom nws thiaj li tawg, uas ib txwm tsis tuaj yeem ua tau hauv cov xwm txheej hauv tsev. Lwm qhov tshwj xeeb ntawm anaerobics yog kev sib xyaw tsuas yog nrog cov tshuaj zoo sib xws hauv cov muaj pes tsawg leeg, uas tsis ib txwm zoo ib yam txawm tias nyob hauv kab ntawm tib yam, thaum xub thawj siab ib muag, sealants. Thaum yuav ib lub peev xwm ntxiv ntawm qhov muaj pes tsawg leeg, nws yog qhov zoo dua kom paub qhov tseeb qhov sib khi tau ua tiav ua ntej, thiab xaiv qhov sib xyaw ua ke uas zoo ib yam li ua tau rau yav dhau los.

Acrylic foob nrov heev rau kev ua haujlwm sab hauv, tshwj xeeb tshaj yog ua tiav thiab kho kom zoo nkauj. Nws yog qhov nyab xeeb tshaj plaws, ib puag ncig zoo tshaj plaws, qhuav sai, thiab tsis hnov ntxhiab. Thaj chaw ntawm nws daim ntawv thov yog nqaim heev - acrylic tsis ruaj tsis khov rau qhov kub thiab txias, tawg los ntawm deformations thiab kev co nyob rau hauv siab, thiab qis elasticity tsis tso cai rau lawv los ua ke ua ke qhov chaw ntawm cov txheej txheem. Xws li lub foob yog qhov zoo rau siv hauv lub tsev sov, thaum cov av noo yuav tsum tsis txhob siab dhau.

Dua li qhov tseeb tias txhua tus acrylic tau ua los ntawm cov dej, cov foob kuj tseem tau cais ntawm no raws li tsis muaj dej thiab tsis tiv thaiv dej. Ordinary acrylic kua nplaum yaj nrog dej, nws tuaj yeem pleev xim rau hauv cov xim uas xav tau nrog tib xim acrylic, yog tias qhov yooj yim dawb lossis hloov kho pob tshab tsis txaus siab. Los ntawm qhov kub dhau los lossis tiv nrog cov dej noo, nws tuaj yeem tawg hauv ob peb hnub tom qab siv, tab sis rau cov yas thiab, qhov tseem ceeb tshaj plaws, qhov chaw qhuav, nws zoo meej thiab yuav nyob ntev.

Waterproof acrylic sealant tsis tuaj yeem hu ua tsis muaj kev phom sij rau tib neeg, tab sis qhov muaj peev xwm ntawm nws siv yog dav dua. Nws muaj cov nplaum zoo, uas yog, nws tuaj yeem ua ke nrog ntau qhov chaw, txawm tias tsis sib xws thiab nrog txheej xim yav dhau los. Koj tseem tuaj yeem lo cov nqaws nrog lawv txawm tias nyob hauv chav da dej, vim tias cov dej tsis muaj dej acrylic ib txwm ua rau cov dej noo nyob ib puag ncig ib ntus. Txawm li cas los xij, koj yuav tsum tsis txhob siv nws nyob hauv qhov chaw sib cuam tshuam nrog dej xws li pas dej, tsis muaj acrylic yuav tiv taus cov khoom hnyav no.

Lwm hom acrylic sealant yog cov nplaum nplaum. Muaj kev ywj pheej siab thiab tsis tuaj yeem hloov pauv, nws feem ntau siv rau kev teeb tsa ua haujlwm hauv kev kho lub qhov rooj thiab qhov qhib qhov rai. Ntawm qhov zoo ntawm cov ntaub nplaum, ib tus tuaj yeem nco lub peev xwm los pleev xim rau qhov ua tau zoo tsis tsuas yog nrog cov xim acrylic, tab sis kuj nrog cov roj zoo tib yam.

Bituminous foob nrov heev txij li lub sijhawm puag thaum ub, vim nws yooj yim hauv kev ua haujlwm, nce lub zog thiab ua kom nrawm. Ntxiv rau ntuj bitumen thiab cov khoom siv roj hmab, nws muaj cov tshuaj polymer ntxiv, ua tsaug uas cov ntawv foob no siv tau rau yuav luag txhua yam kev kho. Feem ntau nws yog siv thaum kho lub ru tsev slate lossis pobzeb, nrog rau lub hauv paus thiab lub hauv paus ntawm laj kab. Cov khoom siv bituminous kuj tseem zoo rau kev nqa tawm kev sib txuas lus thiab txuas cov pob qij txha hauv cov kav dej.

Yeej, bitumen yog cov khoom tsim los ntawm cov khoom siv roj av thiab zoo li cov roj dub lossis kua roj hmab. Cov qauv no muaj cov viscosity zoo heev thiab cov khoom ntws, yog li cov sealant sib npaug siv rau qhov nyuaj tshaj plaws thiab tsis sib xws. Ntawm nws cov pob nws tau sau ntau zaus tias bitumen tau siv rau ib qho, txawm tias qhov tsis huv. Qhov no tsuas yog siv rau cov xwm txheej thaum cov hmoov av lossis cov khib nyiab tsim kho me me nyob ntawm cov khoom kom raug kaw. Yog tias qhov saum npoo tsis tau ntxuav ntawm cov xim dhau los thiab cov kua roj vanish, tom qab ntawd cov nplaum yuav tsis tshwm sim, thiab tag nrho cov txiaj ntsig yuav ploj tom qab ib hlis.

Lub hauv paus keeb kwm ntawm bitumen cob kuj tseem txiav txim siab nws cov khoom zoo heev hydrophobic, yog li ntawd, cov khoom siv foob feem ntau siv tsis yog txhawm rau txhawm rau nqaws, tab sis kuj yog cov neeg ua haujlwm tiv thaiv dej. Lawv nyiam siv cov khoom zoo li no hauv lub tebchaws lossis hauv lub zos kom tiv thaiv cov kav dej rau cov dej nag lossis cov kav dej hauv cov tsev ntiav. Bitumen zoo tsis tsuas yog vim nws tsis muaj dej, tab sis kuj vim nws muaj peev xwm tiv thaiv kev tsim cov pwm thiab kab mob.

Qhov ntxiv ntawm polymers rau cov muaj pes tsawg leeg tau nthuav dav qhov kev thov ntawm bitumen sealant, txij li nws tau dhau los ua kom khov-tiv taus thiab yog li ntawd haum rau kev ua haujlwm sab nraum zoov. Tsis tas li, cov nqaws glued nrog bituminous fillers tsis sag lossis tawg thaum lawv qhuav. Yog tias peb coj mus rau hauv tus account tus nqi qis dua ntawm cov foob no hauv kev sib piv nrog tib lub silicone lossis acrylic, tom qab ntawd koj tuaj yeem tau txais tus nqi zoo tshaj piv nrog kev ua haujlwm ntev ntawm cov khoom.

Txawm hais tias nws muaj kev tiv thaiv zoo rau kev cuam tshuam ib puag ncig cuam tshuam thiab qhov kub thiab txias, bituminous sealant yuav tsum tsis txhob siv rau hauv kev tsim cov pa taws, chav rhaub dej kub lossis chav saunas. Yog lawm, nws ua siab ntev rau qhov cuam tshuam ntawm hluav taws xob ultraviolet, yog li tsis muaj dab tsi tshwm sim rau nws thaum tshav kub sab nraum. Txawm li cas los xij, nrog qhov kub nce siab tshaj 50 ° C, nws tuaj yeem yaj me ntsis thiab rov qab mus rau nws lub xeev qub ntawm kev sib sau ua cov kua ua kua.

Ntawm qhov kub qis, koj tuaj yeem ua haujlwm nrog bitumen yam tsis ntshai , tab sis tom qab ntawd nws lub peev xwm los tiv taus qhov kev co muaj zog ploj, uas yog qhov tshwj xeeb tshaj yog thaum sib khi lub hauv paus. Rau hom kev kho haujlwm no, nws yog qhov zoo dua los xaiv cov roj hmab foob uas muaj kwv yees li cov txheej zoo ib yam li bituminous, tab sis tib lub sijhawm tseem tiv taus qhov cuam tshuam ntawm tshee ntawm qhov kub ntau txaus: los ntawm -50 ° C txog li + 60 ° C.

Lwm qhov teeb meem tseem ceeb ntawm cov ntaub nplaum yog nws cov xim dub ci, thiab nws tsis tuaj yeem pleev xim. Qhov no txhais tau tias bitumen tsis haum rau sab hauv lossis ua haujlwm zoo nkauj yog tias tus tswv muaj kev txhawj xeeb txog kev ua kom zoo nkauj ntawm cov nqaws. Ib qho kev zam yog qhov xwm txheej raws li qhov xim dub ntawm sab hauv, piv txwv li, hauv chav dej, yog tus sau lub tswv yim. Tom qab ntawd ci ntsa iab roj ntxoov ntxoo ntawm bitumen, ntawm qhov tsis sib xws, yuav koom ua ke nrog ib puag ncig.

Nws tsis yog tsis muaj dab tsi uas nws tau siv feem ntau rau sab nraum zoov ntawm kev ua haujlwm: ua tshuaj lom heev, nws tso cov tshuaj tsis zoo thaum lub peev xwm tsis ua haujlwm, tshwj xeeb tshaj yog nyob rau qhov kub thiab txias. Ib tus neeg muag khoom twg yuav pom zoo xaiv cov hnab looj tes thiab daim npog ntsej muag kom muaj kev nyab xeeb rau tuav lub foob no. Nws yuav zoo li ntuj bitumen nws tus kheej, uas yog lub hauv paus ntawm kev sib xyaw, yog cov khoom uas muaj kev nyab xeeb rau tib neeg thiab tsis nqa cov co toxins thiab carcinogens. Qhov phom sij nyob hauv cov tshuaj polymer ntxiv, tab sis ua tsaug rau lawv, cov hlua yuav dhau los ua yas tom qab siv.

Yog tias kev nkag mus ntawm lub foob rau hauv lub ntsws yog qhov tsis xav tau heev, tom qab ntawd tiv tauj nrog daim tawv nqaij, koj yuav tsum tsis txhob ntshai kub hnyiab. Tau kawg, cov muaj pes tsawg leeg tsis tuaj yeem ntxuav nrog cov dej dawb zoo li acrylic. Lub foob tuaj yeem so ntawm txhais tes nrog tus ntsuj plig dawb, thiab yog tias nws tsis nyob ntawm tes, tom qab ntawd nrog cov ntsia thawv txhuam tas li ib txwm, tsuas yog nyiam nrog cov ntsiab lus acetone.

Cov khoom siv bituminous muaj cov khoom tiv thaiv zoo corrosion , yog li nws yog qhov kev xaiv zoo tshaj plaws thaum txhim kho cov ntawv txhawb nqa hlau, ntxiv rau gluing pob qij txha hauv lub ru tsev. Nws yog qhov zoo kom haum cov kab hlau rhuav kab hlau rhuav, cov ntawv sib txuas, cov txuas txuas xws li tus tuav lub kav hlau txais xov ntawm nws.
