Silicone ukushisa ukumelana: izinhlobo kanye nezici zabo

Ngo ukwakhiwa ngokuvamile kuyadingeka e uphawu ukuqhekeka nezihlanganiso wadalula okusezingeni eliphezulu lokushisa ukuchayeka. Kusho ukuxazulula izinkinga ezinjalo kumelwe kanyekanye ukumelana lokushisa ekushintshashintsheni kanye nokugcina nakalula. Ukufohla yangempela kulo mkhakha kwakuyisazi kokusungulwa laqanjwa ekhethekile, okuyinto eyenziwa ngesisekelo abicah zenjoloba.

Izici isicelo

Ngaphambi kokufaka isicelo silicate ayinhlama kudingekile imanzise ebusweni. Resistant abicah kumele kusetshenziswe ezingeni lokushisa ezisukela +5 ukuba + 40 °. Uma ezingeni lokushisa elifanele lehla ngaphansi kwezinga-qhwa, ukwakheka omane lukhuni. Njengoba izinga lokushisa elikhulu ukuze isetshenziswe ukubonisa zezitsha zempepho + 20 °. Master ngempela zisebenzisa PPE ngesimo amagilavu, kusukela uphawu abicah ingxube ingaqukatha izinto ezingabanga chemical ukusha phezu kwesikhumba.

Ukuze ugweme ukungcoliswa evele, okuyinto akufanele kube kuncike isicelo se-sealant okufanele isetshenziswe lezisekelo zawo isalothephu lenkhulu, okuyinto ethe njo nhlangothi zombili we umphetho. Ochwepheshe ukweluleka ukunamathela ngokuqinile ezimisweni imiyalelo, okuyinto ukuhlinzekela ukushuba we umthungo, akufanele futhi iyophakama kuno-letiphakanyisiwe. Lokhu kungenxa yokuthi kukhona ingozi imifantu ukuvela kokuthi ukusebenza elinama engasoze lukhuni.

ezihlukahlukene sealants

Silicone Kusekelwe polymers ukushisa ukumelana, okuyinto engase ihluke kakhulu, onikeza ukubunjwa izici ezithile. Kwasetshenziswa Izingxube anjalo amashubhu okungase ziyahlukahluka ngobukhulu futhi ukumisa. On ukudayiswa ungathola ukwakhiwa ezimbili-ingxenye ukuthi ngaphambi kokuqala umsebenzi, isidingo sokuba kunakekelwe ngokwezinto kuhlangana. Kaningi bajwayele ochwepheshe ngoba ukubunjwa izidingo esiqinile. Lapho ukuxuba isilinganiso ukuba ngokuqinile ulandela imiyalo. Nokho, iphutha isamukeleka, kodwa g 1 kuphela Uma izithako axutshwa kahle, ngeke kube khona ukusabela, kanye nokufaneleka abicah kuyinto amahora ambalwa kuphela.

Ukuze ukuxazulula izinkinga zasekhaya kungcono ukusebenzisa elinye izinhlobonhlobo abicah sealants, okuyinto uvezwa unamathisele ifomu, njengoba letihambisana ukusetshenziswa lula. Ukuze amaziko kanye kushimula wakhuthaza ukuthola ephezulu lokushisa izingoma, tiniketwe ukudayiswa ngesimo a, ukushisa ukumelana nokushisa ukumelana izinto ukushisa ukumelana.

Izici sealant ukushisa ukumelana

Silicone ingenye izinhlobo ukushisa ukumelana we izingoma echazwe futhi isetshenziswa zindawo eziku-operation sishisiswe 350 °. ensimini yabo kwesicelo - evele elingaphandle fireplaces nemifantu. Nge sealant ukushisa ukumelana anganqanda igebe phakathi kwezitini ku akhiwe. Nokho, phakathi kwesithando somlilo asakazwe ukusebenzisa sealant ukushisa ukumelana akudingekile. Ingasetshenziselwa bonyana batshidze panel isemishi ukufulela, kanye enhlanganisweni yebhantshi lensimbi, isitini noshimula.

Kodwa kule zikhona ezehlukile, ezingalotshwanga obonakaliswe metal noshimula. Kodwa ukuvala igebe e Ukushisa amanzi ashisayo supply system usebenzisa ukushisa ukumelana sealant ikani.

Ngakho, ukuthuthukisa ukumelana ukushisa sengezwe izithako zensimbi oxide. anamathelayo okunjalo babhekane nethonya lokushisa 250 °. Kafushane lokushisa ongama ku 315 °. Uma, phakathi izithako oxide yensimbi likhona, unama kuyodingeka abe luhlaza iba nsundu ngokubomvu. Izingxube okunjalo asetshenziselwa fireplaces noma izitofu eyakhiwe ngezitini.

Surface ukubukeka lapho Slots kunqanyulwe isivumelwano se konakalisa ngeke, ngoba sealant cishe ezingabonakali. Kubalulekile ukuba banake indlela yokwakheka abicah sealant, njengoba kungaba hlangothi noma ene-asidi. Kulo mBhalo, i-solidification izonikezwa acetic acid. Izingxube okunjalo ngeke likwazi ukusebenziseka kwi ezisansimbi ezingesiyo ukumelana ukugqwala.

izici engeziwe we sealant ukushisa ukumelana

Izingxube achazwe ngenhla esitebeleni UV ukukhanya, ngakho-ke angasetshenziswa ngesikhathi nokusetshenziswa ongaphandle, nokunamathelisa ukudlula ophahleni. Basuke zihlukaniswa okusezingeni eliphezulu ukumelana namanzi FUTHI OBUMBENE. Ukwakheka azigcina ductility, awusebenzi crack ngaphansi vibration kanye deformation. Ijubane sokwelapha kungaba kusuka amahora ambalwa kuya ezinsukwini ezimbalwa, lesi sici kuzoncika ukubunjwa ingxube.

izici Kobuchwepheshe ukushisa ukumelana sealant

Heat ekumelaneni abicah sealant ayinhlama enzelwe ukugcwalisa izikhala phezu, ezisebenza ezingeni lokushisa kusuka 1200 kuya 1300 °. Ukwanda lezivakashi kungenzeka kuze kufinyelele 1600 °. Ngakho-ke, idatha sealants avame ukusetshenziswa ezindaweni lapho kungase kube ukuxhumana ngqo i ilangabi evulekile. Uma uhlela ukuba bahlangane ngefasitele nanoma isiphi esinye isakhiwo ukuthi kuyoba egoqekayo, kubalulekile ukucubungula amalunga omzimba. Ngezinye nokubhidliza amayunithi ezimbili bazokwazi ukuchoboza ukuhlukanisa izingxenye uphawu. Uma singalitholi evele uphawu ukuba zihlanganiswa, isakhiwo ngeke cishe Monolithic, niyise ngaphandle ngaphandle kokulimaza engasebenzi.

Ukushisa ukumelana abicah anamathelayo babe adhesion abampofu lungisani izinto, ngakho ngaphambi isicelo we ebusweni olwalwenza ukuphathwa ngayo, bese futhi wageza degreased. Ngaphambi ebusweni uphawu kungenzeka Ukwakheka ngokuzikhethela elina uncured isuswe ngendwangu emanzi. Ezinye izingoma zihlanganisa nesidingo sokuba ukudala izimo ezikhethekile. Ngakho, isithando somlilo kufanele sealants omisiwe amahora ambalwa ngesikhathi obuhlukahlukene omlilo umfutho. Uma ukufeza ngokunembile oda, sizokwazi ukuthola uphawu noma umphetho.

abicah sealant Incazelo KLSE ngokudala amafomu

On ukudayiswa ungathola olunye uhlobo sealant - ukushisa ukumelana abicah isikhunta. Umkhiqizo kwaphumela kungenziwa eziqhutshwa ezingeni lokushisa lapho ingeqi 400 °. Uma lokhu embundwini kuyoba ephakeme, emva kwesikhashana yakha ngeke kuyaqina. I sealant echazwe laqanjwa flowable ukuthi uba nombala isitini. Kwasetshenziswa njengoba base futhi kulethe ephelele. Solidification kwenzeka phakathi namahora angu-24 ekamelweni lokushisa, ekugcineni kungenzeka ukuthola imikhiqizo iraba-like.

Ingaphezulu yasekuqaleni, okuthiwa ukususa ifomu, kumele degreased, bahlanza of nokugqwala nokungcola, uma kwamanzi kuyinto ukungena nakwamanye amazwe, kungcono ukusebenzisa ukwakheka uhlukanisa. Kufanele baphathwe nenye izihloko zokuqala futhi ikhefu kulesi sifundazwe ngoba noma engaphansi kwalo ngosuku. Uma ezingeni lokushisa elifanele lingaphansi kunalokhu Kunconywa, isikhathi sokwelapha kungenzeka eside. Thuthukisa enkompolo kungadinga isigamu sehora.

Alternatives ukushisa ukumelana abicah sealant

Uma ufuna ukushisa ukumelana abicah gasket, ungakhetha "Pentelast-1110", okuyinto esetshenziswa njengendlela gasket ketshezi emalungeni nasekubekweni uphawu amapayipi threaded. Kuyinto ukulondoloza ukusebenza ezingeni lokushisa kusuka -50 kuya + 250 °. Esifushane ukuchayeka okushisa aphakeme zingenza, kodwa hhayi ngaphezulu kuka-10 amahora. Ngakho thermometer ukuze akhuphukele 300 °.

Lapho elapha akuyona uketshezi ezinobuthi futhi ene-asidi. Uma kudingekile, ungasebenzisa abicah ukudla nemithi RTV 118, Q, esingeyena umbala eyodwa ingxenye ingcina sealant. It sisetshenziswa ekamelweni lokushisa, futhi isimo sokuqala kuyinto unama. Isicelo singenziwa ezindaweni evundla mpo. izinga lokushisa lokusebenza zokhahlamba kusuka -60 kuya + 260 °.

nezinye iziphakamiso

Silicone ukushisa ukumelana ishidi futhi ethandwa kakhulu phakathi uhlobo oluthile lomsebenzi. Ubukhulu we ipuleti ingahluka ku uhla kusuka 300x300 ukuze 500x500 mm. Uhlonze lwalo kuyahlukahluka kusuka 1 kuya 12 mm. Le nto eyenziwe abicah futhi ingasetshenziswa ukudla processing imishini ezingeni lokushisa kusuka -50 kuya + 250 °. Imikhiqizo ziphephile, esitebeleni amakhemikhali, okungezona ezinobuthi futhi imvelo. Isikhunta abicah esetshenziselwa ukukhiqizwa Linings ukushisa ukumelana. Lesi sakamuva singabangela usetshenziselwe ukubekwa uphawu static.

Lapha, ezimelana nokushisa abicah spray kuyinto igrisi jikelele, okuyinto kuvimbela futhi ivikela metal, iraba noma plastic, nezinkuni. Kungaba ikusize uyifinyelele nokuqedwa imisindo ezingemnandi. impahla Manzi kudala ifilimu zokuzivikela okungadingi ushiye amabala okunamafutha.
