Zvese izvi zvine chekuita negonhi nehwindo sealants!
Iko kushandiswa kukuru kwegonhi nemahwindo sealants ndiko kuvharirwa pakati pemagonhi nemahwindo uye girazi, uye kuiswa chisimbiso kwemahwindo emafuremu uye kuvhara madziro. Kana paine dambudziko negonhi nemahwindo sealants, kuvharidzira, kupisa kupisa, kuvharidzira inzwi, kudzivirira mvura uye mamwe mabasa emagonhi nemahwindo acharasika, uye nhevedzano yemamiriro akanyorwa pamusoro achaitika.
Kana zvasvika kumasuo nemahwindo sealants, vanhu vazhinji vanofunga nezve: Chii? Haasi iwo magirazi sealants here? Hongu, ndiyo magirazi sealants anoonekwa kazhinji mumiromo yedu. Asi haisi magirazi sealants chete.

Mubvunzo: Sei ichinzi girazi sealant?
A: Nekuti iyo silicone sealant yakagadzirwa padanho rekutanga ine acidic uye inogona kungoshandiswa kurova girazi, saka munhu wese anoidana kuti girazi sealant negungano. Vatengiwo zvavo vanoziva zvishoma nezve glue, saka munhu wese anotanga kuidaidza kuti girazi sealant.
Mubvunzo: Sei isiri girazi sealant chete?
A: Nokuti ikozvino nekukurumidza kukura kwesilicone rubber industry, sealants haisi kungoita acidic sealants, asiwo batch itsva ye neutral silicone sealants yakabuda. Isu tinoishandisa pamasuo nemahwindo, uye inonzi silicone gonhi uye hwindo glue.
Acidic glass sealant inonyanya kushandiswa kudzivirira mvura uye kuvhara. Kukanganisa kwayo ndeyekuti ine imwe chiyero chekuora, saka zvinhu zvinogona kushandiswa zvishoma. Mukuwedzera, hupenyu huzhinji huri makore maviri kusvika kumakore matatu, uye zviri nyore kuva brittle mushure mezvo; neutral glass sealant ine huwandu hwakawanda hwekushandisa, haina-corrosive, uye inogara kwenguva refu. Kukanganisa kwayo ndeyekuti inorapa zvishoma zvishoma. Sarudzo chaiyo ye sealant inofanirwa kutariswa zvichienderana nemamiriro chaiwo.
Mubvunzo: Ko gonhi nehwindo sealant inodzivirira mamiriro ekunze?
A: Mhando dzezvisimbiso zvinoshandiswa pamasuo nemahwindo dzinosanganisira: silicone sealant, polyurethane sealant, mvura-based sealant uye silane-modified polyether sealant, pakati peiyo silicone sealant inosarudzwa. Silicone sealant ine yakanyanya kupikisa mamiriro ekunze, uye cheni yayo huru yemakemikari bond simba rakakwirira kupfuura simba re300nm ultraviolet mwenje, ndosaka silicone sealant inogona kuchengetedza kuita kwakanaka pasi pe ultraviolet mwenje kwenguva yakareba.
Tora siway 666 yakakwirira-inoshanda zvakatipoteredza ine hushamwari silicone sealant semuenzaniso. Chekutanga pane zvese, haina kwayakarerekera silicone sealant, saka yayo yemamiriro ekunze kumira kwayo kwacho kwakanaka kwazvo. Nokudaro, pasinei nokuti zita racho rakanyorwa seinodzivirira mamiriro ekunze, kupikisa kwemamiriro ekunze kwesilicone sealant hakugoni kubvunzwa.
Nzira yekusarudza gonhi nehwindo sealant
Sealant inongoverengera 1 ~ 3% yemutengo wakazara wemagonhi ekuchengetedza simba nemahwindo, asi hunhu hwayo hunokanganisa zvakananga kunaka uye simba rekuchengetedza simba reprojekiti yese, uye zvakare inokanganisa zvakananga ruzivo rwedu rwekurarama. Vanhu vanowanzo tarisa zvakanyanya kune "zvinhu zvihombe" zvakaita segirazi nemaprofile, uye kufuratira zvinhu zvidiki zvechisimbiso. Vanhu vashoma vanoziva kuti gonhi nehwindo sealant chinhu chakakosha. Iko kurasikirwa kwesimba kunokonzerwa nekukundikana kwegonhi uye kuvhara kwehwindo kwakakura kudarika simba rekuchengetedza rinogona kuwanikwa nekusarudza zviri nani girazi uye profiles. Kutaura nezvekuchengetedza simba uye kuchengetedza kwezvakatipoteredza muchivako chinodonhedza mhepo nemvura kwakafanana nekutaura kusina maturo.
Kuvharika kwemamiriro ekunze uye kusavharwa nemvura kwemagonhi nemahwindo chirongwa chakarongeka, semadziro eketeni, kusanganisira kuvhara pakati pemahwindo nemagirazi, kuvharika pakati pemadziro ekunze nemafuremu egonhi nemahwindo, nezvimwewo. Muchirimo, kupenya kwezuva kune simba uye Mamiriro ekunze akanyanya semadutu nemadutu emvura anowanzoitika. Inguva yakakwira-chiitiko chematambudziko egonhi nemahwindo. Ndedzipi nyaya dzatinofanira kutarisisa pakusarudza uye kushandisa silicone sealants kumagonhi nemahwindo?
1. Sarudza zvigadzirwa zvenguva dzose zvinosangana nemitemo yenyika
GB/T 8478-2020 "Aluminium Alloy Doors uye Windows" inoisa mberi zvinodiwa zvekuisa chisimbiso uye zvekubatanidza zvealuminium alloy magonhi nemahwindo. Mukuwedzera, GB/T 14683-2017 "Silicone uye Modified Silicone Building Sealant", JC/T 881-2017 "Sealant for Concrete Joints", JC/T 485-2007 "Elastic Sealant Yekuvaka Windows" uye mamwe maitiro akaiswawo anoenderana. zviratidzo zvezvisimbiso zvekuvaka magonhi nemahwindo.
2. Sarudza yakavimbika mhando hombe
Mukova uye hwindo glue musika wakasanganiswa, neanogara mabrand uye copycat brands ari kubuda murukova rusingaperi, uye kune zvakare zvigadzirwa zvemanyepo. Sarudza yakajairika mhando hombe ine simba rehunyanzvi kuita tsvakiridzo yekuita kwechigadzirwa, nyatso kudzora zvigadzirwa uye maitiro ekugadzira, uye zvigadzirwa zvinokwanisa kutumirwa chete mushure mezvikamu zvekuongorora, kuitira kuti mhando ivimbiswe.
3. Nyatsocherechedza kushanda kwezvakatipoteredza kwechigadzirwa
Panyaya yekusagadzikana, zvinyorwa zveVOC, simbi inorema, nezvimwe zvechisimbiso, zvakaoma kuti vatengi vaone chero zviratidzo kubva pachigadzirwa nemeso avo asina kupfeka. Zvinokurudzirwa kutarisisa kuchengetedzwa kwezvakatipoteredza kwemugadziri wechigadzirwa, sekunge akapfuura ISO9001 quality management system, ISO14001 Environmental Management System, ISO45001 Occupational Health and Safety Management System, uye kana iine chiremera chechitatu-bato. Environment protection qualification certification.
4. Kuvaka kwakarurama
Silicone sealant inobatwa zvakanyanya nenharaunda (tembiricha uye humidity). Iyo yakawanda inoshandiswa nharaunda inoda kuti inofanirwa kushandiswa munzvimbo yakachena ine tembiricha ye5 ~ 40 ℃ uye hunyoro hwe40% ~ 80%. Naizvozvo, hazvikurudzirwe kuisa glue munzvimbo inodarika iyo iri pamusoro.
Mukuwedzera, zvakakosha kubhadhara kune yakachena uye yakaoma pamusoro pemasuo nemahwindo ekugadzirwa. Muzhizha, tembiricha uye hunyoro zvakakwirira, uye kutarisisa kunofanirwa kubhadharwa pakuisa glue nekukurumidza (kana primer ichidikanwa, isa glue nekukurumidza mushure mekuisa primer), uye kuchekerera kunofanira kuitwa nekukurumidza mushure mekupera. Mushure meizvi, inofanira kuporeswa kweanopfuura maawa gumi nemaviri pasi pemamiriro ekusimudzira uye asina kusimbiswa maererano nemamiriro ekurapa ezvigadzirwa zvakasiyana.
5. Kuchengetedza kwakarurama
Kupisa kwepamusoro uye kunyorova kwemamiriro ekunze kuchapfupisa zvakanyanya nguva yekuchengetedza yechigadzirwa uye kuita kuti chigadzirwa chisakundikana nguva isati yakwana. Nokudaro, zvinokurudzirwa kushandisa sealant nokukurumidza sezvinobvira mushure mekuvhura muzhizha. Muzhizha, kune hunyoro uye kunaya. Izvo zvinofanirwa kucherechedzwa kuti sealant inofanirwa kuchengetwa munzvimbo inofefetera uye inotonhorera ine nzvimbo yakadzika kudzivirira iyo sealant kubva pakunaya kwemvura kana kunyange kunyudzwa kwemvura kunokonzerwa nekunyanyisa kwemamiriro ekunze, izvo zvinokanganisa hupenyu hwesherufu yechigadzirwa uye kukonzera kurapa. matambudziko mune chigadzirwa kurongedza.
Vazhinji vashandisi vane hurombo hwekuisa chisimbiso kuita kwemagonhi nemahwindo kumba, uye pfungwa yekutanga ndeyekutsiva magonhi nemahwindo - ikozvino tinoziva kuti izvi hazvidiwi. Chekutanga, nyatso tarisa kana gonhi uye hwindo glue rakatsemuka, rakaomarara, kana kuita kushomeka kwekuvhara. Kana dambudziko riri nechisimbiso, saka iwe unongoda kuchitsiva nepamusoro-mhando silicone sealant ine yakavimbiswa mhando.
