Sezvatinoziva tese, zvivakwa zvinowanzotarisirwa kuve nehupenyu hwesevhisi hweanenge makore makumi mashanu. Nokudaro, zvinhu zvinoshandiswa zvinofanirawo kuva nehupenyu hurefu hwebasa. Silicone sealant yakashandiswa zvakanyanya mumunda wekuvaka kudzivirira mvura uye kuvhara nekuda kwekunaka kwayo kwepamusoro uye yakaderera tembiricha kuramba, yakasarudzika mamiriro ekunze kuchembera, uye yakanaka yekubatanidza zvivakwa. Nekudaro, mushure menguva inotevera kuvakwa, discoloration yesilicone sealant yave nyaya inowanzoitika, iyo inosiya kamwe kamwe "mitsara" pazvivakwa.
Sei silicone glue ichichinja ruvara mushure mekushandisa?
Pane zvikonzero zvakawanda zvekusarudzika kana kuzara kwesilicone tunnel sealant kana girazi glue, kunyanya mune zvinotevera zvinhu:
1. Kusapindirana kwezvinhu zvakasiyana-siyana zvechisimbiso Acidic sealants, neutral alcohol-based sealants, uye neutral oxime-based sealants haigoni kushandiswa pamwe chete, sezvo inogona kukanganisa mumwe nomumwe uye inokonzera kushanduka. Acidic girazi sealants inogona kukonzera oxime-based sealants kushanduka yero, uye kushandisa kwaakarerekera oxime-yakavakirwa uye kwaakarerekera doro-based girazi sealants pamwe chete kunogona kukonzera kutsvuka.
Mamorekuru anoburitswa panguva yekurapa kweasingarereki oxime-mhando sealants, -C = N-OH, anogona kuita nemaacids kuti aumbe mapoka emaamino, ayo anonyorerwa nyore nyore neokisijeni mumhepo kuti agadzire zvinhu zvine mavara, zvichiita kuti chisimbiso chive nemavara.
2. Kubata nerabha nezvimwe zvinhu
Silicone sealants inogona kushanduka yero kana yakanangana nemamwe marudzi erabha, seyakasikwa rabha, neoprene rabha, uye EPDM rabha. Aya marabha anoshandiswa zvakanyanya mumadziro emaketeni nemahwindo / magonhi semarubha mitsetse, gaskets, uye zvimwe zvikamu. Uku kushanduka kwemavara kunoratidzwa nekusaenzana, uye zvikamu chete zvinosangana zvakananga nerabha ichishanduka yero nepo dzimwe nzvimbo dzichiramba dzisina kukanganiswa.
3. Sealant discoloration inogonawo kukonzerwa nekunyanya kutambanudza
Chiitiko ichi chinowanzonzi chinokanganisa kurasikirwa kwemavara echisimbiso, izvo zvinogona kukonzerwa nezvinhu zvitatu zvakajairika.
1) Iyo sealant yakashandiswa yakapfuura kugona kwayo kusimuka uye iyo joint yakatambanudzwa zvakanyanya.
2) Ukobvu hwechisimbiso mune dzimwe nzvimbo hwakanyanya kutetepa, zvichikonzera shanduko yemavara yakatarisana munzvimbo idzodzo.
4. Kuchinja kwechisimbiso kunogonawo kukonzerwa nemamiriro ekunze.
Rudzi urwu rwekushanduka ruvara rwakanyanya kuwanda mune zvakarerekera oxime-mhando sealants, uye chikonzero chikuru chekuchinja kuvepo kwezvinhu zvine acid mumhepo. Kune zvakawanda zvinobva kune acidic zvinhu mumhepo, sekurapa acidic silicone sealant, acrylic coatings anoshandiswa mukuvaka, yakakwira sarufa dioxide mumhepo munguva yechando munzvimbo dzekuchamhembe, kupisa marara epurasitiki, kupisa asphalt, nezvimwe. Zvese izvi zvinhu zvine acidic zviri mumhepo zvinogona kukonzera oxime-type sealants kudzima.
Nzira yekudzivirira sei kusvibiswa kwesilicone sealant?
1) Asati avaka, ita bvunzo yekuenderana pane izvo zvinosangana nechisimbiso kuti uve nechokwadi chekuenderana pakati pezvigadzirwa, kana sarudza zvimwe zvinowirirana zvekushandisa, sekusarudza zvigadzirwa zverabha zvesilicone pachinzvimbo chezvigadzirwa zverabha kuderedza mukana wekutsvuka.
2) Panguva yekuvaka, neutral sealant haifaniri kunge yakabatana ne acid sealant. Izvo zvinhu zveamine zvinogadzirwa nekuora kweine kwazvakarerekera sealant mushure mekusangana neasidhi inozoisa mumhepo uye kukonzera kushanduka.
3) Dzivisa kubata kana kuratidzwa kwechisimbiso kunzvimbo dzinoparadza senge acids uye alkalis.
4) Discoloration inonyanya kuitika mumagetsi-mavara, machena, uye akajeka zvigadzirwa. Kusarudza zvisimbiso zvakasviba kana zvitema zvinogona kuderedza njodzi yekushanduka.
5) Sarudza zvisimbiso nemhando yakavimbiswa uye yakanaka brand mukurumbira-JUNBOND.
