Automotive sealants
Txheem
Automotive sealant yog cov kua nplaum zoo li cov khoom siv los tshem tawm cov xau hauv lub tsheb. Thaum siv kom raug, qhov muaj pes tsawg leeg tuaj yeem tshem tawm cov xau ntawm cov tshuaj tiv thaiv kab mob, dej, roj thiab lwm yam dej hauv tsheb. Nws kuj tseem siv tau los khi ntau qhov chaw thiab sau cov kab nrib pleb.
Hom automotive sealants
Lub tsheb sealants tuaj yeem raug cais raws li ntau yam, tab sis feem ntau ntawm lawv yog: los ntawm cov khoom xyaw (silicone, anaerobic, hluavtaws, polyurethane thiab kub) thiab los ntawm thaj tsam ntawm daim ntawv thov (rau lub cev, lub log tsheb, lub tshuab tso pa, rau radiator, rau qhov rais thiab headlights, rau lub cav, thiab lwm yam).
Silicone sealants
Silicone-raws li sealants yog kub-resistant thiab tuaj yeem tiv taus kub txog +300 ° C. Lawv tuaj yeem siv rau feem ntau cov cav tov. Cov khoom ntim cov khoob mus txog 6 hli tuab thiab tiv taus kev kub siab thiab kev khiav hauj lwm ceev.
Thaum ua hauj lwm nrog silicone high-temperature sealant rau lub tsheb, nws yog ib qho tsim nyog yuav tsum tau ua tib zoo ntxuav cov khoom kom sib koom, uas yog qhov tsis zoo me ntsis.
Cov cheeb tsam ntawm daim ntawv thov ntawm silicone compounds: sealing qhov sib txawv mus txog 7 hli nyob rau hauv qhov loj ntawm txhua qhov chaw ntawm lub cav, gearboxes, pem hauv ntej thiab nram qab axles ntawm lub tsheb, cov pob qij txha thiab mating ntawm lub tog raj kheej liners, nrog rau cov gluing qhov chaw ua los ntawm yas thiab iav - headlights, sidelights, hatches, nres teeb.
Anaerobic sealant
Anaerobic sealants muaj xws li cov khoom uas tawv thaum sib cuag nrog hlau nto nyob rau hauv nqaim qhov khoob qhov twg atmospheric oxygen tsis nkag. Yog li ntawd, nyob rau hauv thiaj li yuav muaj pes tsawg leeg rau polymerize, nws yog tsim nyog los nruj nreem txuas cov nto ntawm qhov chaw.
Qhov zoo ntawm cov tshuaj anaerobic kuj suav nrog kev ua haujlwm siab rau cov tshuaj lom neeg ib puag ncig, kev co, kev hloov siab thiab kub. Cov muaj pes tsawg leeg kuj tiv thaiv kev tsim ntawm corrosion, oxidation, roj thiab kua to.
Ib qho tsis zoo ntawm cov khoom siv yog qhov txhaws ntawm qhov sib txawv me me ntawm 0,05 txog 0,5 hli. Yuav kom polymerize cov muaj pes tsawg leeg ntawm cov hlau tsis yog hlau los yog ntawm qhov kub thiab txias, yuav tsum muaj tus activator.
Lub peev xwm ntawm daim ntawv thov ntawm anaerobic sealants yog sealing, kho thiab sealing threaded thiab flanged kev twb kev txuas, cylindrical qhov chaw thiab welds.
Synthetic sealant
Synthetic sealants yog ib yam khoom tshiab uas tseem tsis tau muaj koob meej ntawm cov kws kho tsheb thiab cov neeg nyiam tsheb. Txawm li cas los xij, cov khoom no muaj ntau qhov zoo:
Siab elasticity.
Ua haujlwm rau cov av noo siab, hluav taws xob ultraviolet, thiab kev puas tsuaj rau txhua yam.
Cov khoom nplaum siab, uas tso cai rau koj kom tsis txhob muaj kev kho mob ua ntej ntawm qhov chaw ua ntej siv lub sealant.
Yooj yim ntawm kev siv.
Multifunctionality thiab versatility.
Qee tus kws kho tsheb pib thiab cov neeg nyiam tsheb hais txog nws qhov kev ua tau zoo raws li qhov tsis zoo ntawm cov khoom siv. Ntau tus neeg nyiam qhov nqaim-profile sealants tsim rau cov ntsiab lus tshwj xeeb thiab cov khoom ntawm lub tsheb.
Polyurethane sealant
Nws nplaum qhov chaw sib txawv thiab tsim nyob rau hauv ntau yam xim, uas tso cai rau koj xaiv qhov ntxoov ntxoo rau kev kho hauv qhov chaw pom. Polyurethane tebchaw yog siv los ua sealants rau gluing tsheb qhov rais iav, kho lub taub hau, rau sealing seams, thiab kuj rau tshem tawm qhov khoob ntawm lub cev.
Kub sealant
Siv rau tag nrho cov cav tov thiab lwm qhov chaw. Cov khoom sib xyaw yog tsim uas tuaj yeem tiv taus cua sov txog 3500 degrees. Tab sis rau kev kho lub cav compartment qhov chaw, nws yog txaus kom tiv taus mus txog 2000 degrees.
Cov cheeb tsam ntawm daim ntawv thov ntawm nws pib sealants
Nyob ntawm nws lub hom phiaj, cov khoom siv los ua cov sealant rau:
tsheb taub hau. Tso cai rau koj los kho qhov nruj ntawm cov optics yog tias cov tsom iav taub hau puas lossis hloov.
tsheb qhov rais. Txoj hauv kev zoo tshaj plaws los kaw lub iav pib ntawm lub qhov muag ntawm lub tsheb thiab lwm lub tsheb;
tsheb cav. Txoj kev zoo tshaj plaws los xyuas kom meej qhov kev nyab xeeb ntawm cov txheej txheem ntawm lub hwj chim unit. Siv thaum hloov lub twj tso kua mis, txhawm rau kaw lub valve npog thiab lub lauj kaub kis;
tsheb log tsheb thiab lub log. Pab tawm thaum muaj xwm txheej ceev, i.e. rau punctures thiab puas rau tubed thiab tubeless log tsheb. Tso cai rau koj ua haujlwm kho kho sai sai nyob rau sab nraum zoov;
lub tsheb cua txias. Pab tsis tau tsuas yog tshem tawm, tab sis kuj tiv thaiv kom tsis txhob tso cov tub yees, yog li nws yog feem ntau siv los tiv thaiv kev ntsuas;
tsheb seams. Nws yog siv hauv kev kho lub cev - txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau ntawm lub hood, lub cev, hauv qab, qhov rooj.
xov sealing. Cov khoom sib xyaw tsim los rau cov xov sib txuas tiv thaiv kom tsis txhob xau ntawm qhov chaw tsaws ntawm hoses thiab cov kav dej. Xyuas kom nruj haum ntawm threads txawm nyob rau hauv siab.
Sealant xaiv cov txheej txheem
Thaum xaiv cov sealant, koj yuav tsum tau them sai sai rau kev ua raws li nws cov yam ntxwv thiab kev ua haujlwm ntawm cov khoom.
Ib qho tseem ceeb ntawm kev xaiv cov sealant yog cov khoom ntawm cov khoom siv hauv cov khoom muaj pes tsawg leeg: qib ntawm kev ua haujlwm siab thiab kev vibration loads, elasticity tom qab hardening thiab durability.
Lub xub ntiag ntawm lub dispenser thiab yuav tsum tau siv rab phom sealant kuj ua lub luag haujlwm thaum xaiv lub sealant.
Yog hais tias cov sealing muaj pes tsawg leeg tsis zoo rau qhov kub thiab txias, nws yuav tsum tsis txhob siv rau kev ua cov cav tov.
Tsis tas yuav yuav cov sealants hauv pob loj: koj yuav tsum tsis txhob khaws cov sealant ntxiv, vim tias dhau sijhawm nws yuav poob nws cov khoom.
Cov neeg nyiam tsheb kuj tau them sai sai rau qhov ntev npaum li cas cov khoom siv kom qhuav. Raws li twb tau hais saum toj no, anaerobic compounds harden tsuas yog thaum tsis muaj kev sib cuag nrog oxygen. Qhov no txhais tau hais tias tus neeg tsav tsheb muaj lub sij hawm kom calmly thiab tsis nrawm siv cov khoom rau saum npoo ntawm qhov chaw thiab txuas rau lawv, tsis muaj kev ntshai tias cov khoom yuav nyuaj ua ntej.
Silicone sealants harden nyob rau hauv 10 feeb, tab sis tsis tas yuav tsum tau tshwj xeeb precision ntawm daim ntawv thov, yog li lawv yuav siv tau txawm los ntawm inexperienced tsav tsheb. Ntawm qhov tod tes, kev siv cov khoom siv silicone yog qhov tsim nyog thaum sau qhov sib sib zog nqus, thaum cov tshuaj anaerobic tuaj yeem sau qhov tsis sib xws tsis pub ntau tshaj 0,5 cm tob.
