Izitywino zesiliconezisetyenziswa kakhulu ekwakheni, ekufakeni iiglasi, nasekulungiseni izinto zasekhaya ngenxa yezizathu zazo.ukuguquguquka, ukumelana nemozulu, kunye nobomi obudeKodwa neyona silicone sealant ilungileyo inokungasebenzi kakuhle ukuba isetyenziswe gwenxa okanye phantsi kweemeko ezingalunganga.
Ngezantsi, sichaza iingxaki eziqhelekileyo ngee-silicone sealants, izizathu zazo, kunye nezisombululo ezithatha inyathelo ngenyathelo zokuzilungisa.
1. Ukuncamathela kakubi (Isitywini asinamatheli)
Iimpawu:I-sealant iyaxobuka, iqhekeze, okanye ayibopheleleki kumphezulu.
Izizathu:
-
--Izinto ezimdaka, ezinothuli, okanye ezinamafutha
-
--Ukufuma kumphezulu ngexesha lokufaka
-
--I-substrate engahambelaniyo (umz., i-polyethylene, i-PTFE, okanye imithi enamafutha)
-
--I-sealant ephelelwe lixesha okanye ekumgangatho ophantsi
Indlela Yokulungisa:
-
1. Susa isitywini esingasebenziyo ngokupheleleyo ngesikrapu okanye ngesisusi sesitywini.
-
2.Coca i-substrate nge-solvent (IPA okanye i-acetone) ukuze ususe iioyile kunye nothuli.
-
3.Sebenzisaiprimerukuba inamathele kwizinto ezinemingxuma ezifana nekhonkrithi okanye ilitye lendalo (Uvavanyo lokuncamathela lwe-ASTM C794).
- 4. Phinda ufake i-bead entsha ye-aisitywina se-silicone esingathathi calaukuze kunamathele ngcono
2. Ukubhabhisa okanye ukuVala kwiSealant
Iimpawu:Iipokotho zomoya, amaqamza, okanye amabala angenanto avela ngaphakathi kwe-sealant evuselelweyo.
Izizathu:
-
--Umoya ovalelekileyo ngexesha lokufaka
-
--Ukufuma okugqithisileyo kwilungu (ingakumbi kwiindawo ezinomswakama)
-
--Isitywini sifakwe kakhulu kwiphasi enye
Indlela Yokulungisa:
-
--Sika uze ususe iindawo ezinamaqamza.
-
--Qinisekisa ukuba i-substrate yomile ngokupheleleyo ngaphambi kokuba uphinde uyifake.
-
--Faka isitywini ngokweengqimba xa ugcwalisa amalungu anzulu, usebenzisaiintonga zokuxhasaapho kufuneka khona (Isikhokelo seDow Construction Sealants).
- --Khetha inqanaba lobungcaliisitywina sesilicone esakhiweyoukuze kubekho uzinzo.
3. Ukuncipha okanye ukuqhekeka kweSealant
Iimpawu:I-sealant iyancipha, itsale imiphetho, okanye ivelise imifantu.
Izizathu:
-
--Ukusebenzisa imveliso ekumgangatho ophantsi okanye esekwe kwisinyibilikisi elahlekelwa bubungakanani xa inyibilika
-
--Ukufaka isitywini kubushushu obuphezulu kakhulu
-
--Uyilo olungalunganga lwamalungu (luncinci kakhulu, alunakuvumela ukuhambahamba)
Indlela Yokulungisa:
-
--Susa i-bead enesiphene uze uphinde uyifakei-silicone sealant yonyango olungathathi cala oluphantsi olunciphayo.
-
--Landela uyilo oludibeneyo olucetyiswayo ngokweImigangatho ye-ISO 11600:2002
- --Faka ngaphakathi komgangatho wobushushu ocetyiswayo ngumvelisi (ngesiqhelo yi-5–40°C).
4. Ukukhula koMngundo kunye nokungunda
Iimpawu:Kuvela amabala amnyama okanye amnyama, ingakumbi kwiindawo zokuhlambela nasekhitshini.
Izizathu:
-
--Ukuvezwa ixesha elide kumswakama kunye nokufuma
-
--Ukunqongophala komoya kuloo ndawo
-
--Ukusebenzisa i-silicone engacocekanga kwiindawo ezimanzi
Indlela Yokulungisa:
-
--Sika ngokupheleleyo isitywina esinobume (ukucoca kuphela akusebenzi).
-
--Coca indawo nge-bleach exutyiweyo okanye i-mold cleaner.
- --Faka isicelo kwakhonaisitywina se-silicone esicocekileyokunye nezongezo zokubulala iifungi.
- --Phucula umoya ukuze uthintele ukukhula kwixesha elizayo.
5. Isitywini Asinyangi okanye Sihlala Sincamathele
Iimpawu:I-silicone ihlala ithambile, ithambile, okanye ayisoze iqine.
Izizathu:
-
--Imveliso ephelelwe lixesha okanye indawo egcinwe kuyo engafanelekanga
-
--Indawo yokunyanga engahambelaniyo (ukufuma okuphantsi kwee-silicone ze-RTV ezinenxalenye enye)
-
Impazamo yokuxuba (kwiisilicone ezineenxalenye ezimbini)
Indlela Yokulungisa:
-
--Susa i-silicone engakavuthwa ngokupheleleyo.
-
--Sebenzisa imveliso entsha egcinwe kwindawo epholileyo neyomileyo.
-
--Kwii-silicone eziphilisa umswakama, qinisekisa amanqanaba afanelekileyo okufuma (40–70% RH).
-
--Kwimveliso ezineenxalenye ezimbini, landela umlinganiselo wokuxuba ngokuchanekileyo (Isikhokelo sokuPhilisa isiSealant – BSI).
6. Isitywini Esikhupha Amalunga (Ukusilela Kwamalungu)
Iimpawu:Kuvela izikhewu phakathi kwe-sealant kunye ne-substrate, nto leyo eshiya i-joint ingavalwanga.
Izizathu:
-
--Intshukumo kwi-substrate ngaphaya koluhlu lokuguquguquka kwe-sealant
-
--Uyilo olungalunganga lwamalungu (lunzulu kakhulu okanye alunzulu kakhulu)
-
--Akukho ntonga yomqolo okanye iteyiphu yokuqhekeza ibhondi esetyenzisiweyo
Indlela Yokulungisa:
--Yila kwakhona ijoyinti ngokweImigangatho ye-ASTM C920-18(2024)
--Sebenzisa isitywini esinokukwazi ukushukuma ngendlela efanelekileyo (+/- 25% nangaphezulu).
--Soloko ufaka i-sealant phezu kwentonga yomqolo okanye i-bond breaker ukuze uthintele ukunamathelana kwamacala amathathu.

Izitywini zesilicone ziphakathi kwezisombululo zokuvala ezihlala ixesha elide ezikhoyo—kodwa kuphela xa zisetyenziswa ngokuchanekileyo.iingxaki eziqhelekileyo kunye nokulungiswa kwazo, ungaqinisekisa ubomi benkonzo obude, ukugcinwa okunciphileyo, kunye nokusebenza ngcono kweprojekthi.
At Izitywino zeSiway, sibonelelaizitywina zesilicone ezisebenzayo kakhuluyenzelwe ukunciphisa ezi ngxaki. Nxibelelana nathiiqela lenkxaso yobugcisangeengcebiso zeprojekthi ethile.
Umbuzo 1. Kutheni i-silicone sealant yam inganamatheli kakuhle?
Oku kwenzeka rhoqo ngenxaungcoliseko lomphezulu, ukufuma, okanye ukusebenzisa isitywini esingafanelekanga kwisisekoSoloko ucoca kwaye womisa umphezulu, sebenzisa i-primer ukuba kuyimfuneko, kwaye ukhethe i-silicone sealant efanelekileyo yokulungisa izinto ezibuthathaka ezifana nesinyithi okanye ilitye.
Umbuzo 2. Ndingazilungisa njani iibhamuza okanye izithuba kwi-silicone sealant?
Ukudumba kudla ngokuvela ukuba i-substrate imanzi okanye ukuba i-sealant isetyenziswa ngokukhawuleza kakhulu. Susa icandelo elingasebenziyo, womise umphezulu ngokupheleleyo, uze uphinde uwufake kwi-i-bead ecothayo, eqhubekayoUkuze ufumane iziphumo zobungcali, jonga kuI-ASTM C920-18(2024)izikhokelo zesicelo
Umbuzo 3. Kutheni i-silicone sealant itshintsha ibe ngundo kwiindawo zokuhlambela?
Kwane-silicone “ecocekileyo” inokubangela ukungunda ukuba ichaphazelekaukufuma okungaguqukiyo kunye nokungena komoya kakuhleSebenzisa i-silicone sealant ecocekileyo enezithako ze-fungicide kwaye ugcine indawo yomile xa kunokwenzeka. Ukucoca rhoqo ngezicoci ezingagugiyo kunceda ukwandisa ubomi.
Umbuzo 4. Kuthatha ixesha elingakanani i-silicone sealant ukuphola ngokupheleleyo?
Uninzi lweesilicone luyaphilisa2–3 mm ngosukukodwa ukuqina ngokupheleleyo kungathatha ixesha elide ukuya kuthi gaIintsuku ezisi-7–14, kuxhomekeke kubukhulu beentsimbi, ukufuma, kunye nobushushu. Soloko ujonga amaphepha edatha yobuchwephesha bomenzi ukuze ufumane amaxesha achanekileyo okunyibilika.
Umbuzo 5. Ndingayifaka i-silicone entsha phezu kwe-silicone endala?
Hayi. I-silicone endala kufuneka ibeisusiwe ngokupheleleyokuba isitywini esitsha asizukunamathela kakuhle. Sebenzisa isicoci se-sealant okanye i-mechanical scraper ngaphambi kokuba uphinde ufake isicelo.
Umbuzo 6. Kutheni i-silicone sealant yam ephilisiweyo iqhekeka okanye incipha?
Oku kudla ngokubangelwaukusebenzisa uhlobo olungalunganga lwesitywina kwiindawo ezisebenza kakhuluokanye ukufaka i-bead encinci kakhulu. Kwizihlanganisi zesakhiwo okanye zokwandisa, khetha i-structrual silicone sealant ehambelanaImigangatho ye-ISO 11600 yokukwazi ukuhamba.
