Gyae nkrasɛm bi .
Nnua mfɛnsere wɔ anigyeɛ pɔtee bi wɔ adansiɛ mu-ɔhyeɛ nwene, abɔdeɛ mu hwɛbea, ne atenka a ɛyɛ fɛ a aluminium anaa PVC nhyehyɛeɛ taa ntumi nsi ananmu koraa. Ɛno nti na wɔda so ara de di dwuma kɛse wɔ adan a ɛkorɔn-awieɛ a wɔte mu, nsiesie adwuma, adan akɛseɛ, ne agyapadeɛ a wɔasan asiesie mu.
Nanso sɛ yɛhwɛ nsɔano a, nnua mfɛnsere nso yɛ nneɛma a ɛyɛ den sen biara a wɔde di dwuma no mu biako.
Nnua tu kɔ baabiara. Ɛtwe nsu a ɛwɔ mu no. Ɛtrɛw na ɛtwetwe bere a wim nsakrae ba. Na nea ɛnte sɛ dade anaa plastic a wɔde ayɛ ntama no, ɛnkɔ so yɛ nea ɛyɛ den wɔ ne kɛse mu.
Eyi ne baabi pɔtee a silicone sealant bɛyɛ nea ɛho hia-nanso baabi a nnwuma pii di nkogu nso sɛ wɔpaw ade a ɛnteɛ a.
Wɔ akuw a wɔtɔ nneɛma ne wɔn a wɔyɛ adwuma wɔ hɔ fam no, ɛnyɛ sɛ ebia wobetumi de silicone sealant adi dwuma wɔ nnua so anaa. Ɛda adi pefee sɛ ebetumi ayɛ saa. Asɛmmisa ankasa ne sɛ:a nnuru a wɔde yɛ no betumi atra ase atra ase bere a nnua no keka ne ho wɔ wim tebea mu a ɛrempaapae, ɛrentetew, anaasɛ ɛremfa nkekae mma ne soro.
1. Nea enti a nnua mfɛnsere yɛ beae a ɛhwehwɛ sɛ wɔde nsɔano gu mu
Nea ɛnte sɛ aluminium anaa PVC nhyehyɛe ahorow no, nnua a wɔde yɛ mfɛnsere no yɛ wɔn ade te sɛ "ade a ɛte ase."
Bere a wɔayɛ nnua ho adwuma na wɔayɛ ho adwuma mpo akyi no, ɛkɔ so yɛ n’ade wɔ nneɛma a atwa yɛn ho ahyia ho:
Ɛtrɛw wɔ ɔhyew a ɛkɔ soro mu
Ɛtew wɔ tebea a ɛyɛ kusuu anaa awɔw mu
Ebetumi akyeakyea kakra bere a bere kɔ so no
Ɛnam micro-pores so twetwe nsuo
Bere koro no ara mu no, mfɛnsere mu nkwaa no da:
Osu nsu ne mframa nhyɛso
UV mframa a ɛbɔ
Ɔhyew a wɔde tu sakre (nsonsonoe a ɛwɔ awia/anadwo) .
Nsonsonoe a ɛwɔ dan mu–abɔnten mu nsuo a ɛyɛ nwini mu
Saa nkabom yi ma adwennwen a ɛkɔ so ba sealant nkwaa no so.
Wɔ nnwuma ankasa pii mu no, sealant huammɔdi nyɛ mpofirim-ɛfi ase wɔ micro-movement a ɛde nkakrankakra dan edge cracking anaa debonding.
2. Nea enti a wɔde silicone sealant di dwuma ma nnua mfɛnsere
Ɛmfa ho nsɛnnennen no, silicone sealant da so ara yɛ nneɛma a wɔde di dwuma kɛse wɔ nnua mfɛnsere nhyehyɛe mu no mu biako esiane nneɛma abiɛsa a ɛnyɛ den nti:
(1) Nneɛma a ɛma ɛyɛ den
Silicone kɔ so yɛ nea ɛyɛ mmerɛw bere a bere kɔ so no, na ɛma ɛtwetwe nnua a ɛkeka ne ho a ɛnpaapae.
(2) Wim tebea a ɛko tia
Nnuru a wɔde yɛ nnuru a ɛfata no gyina osu, UV a ɛda adi, ne ɔhyew kyinhyia ano yiye koraa sen acrylic anaa semɛnte-based fillers.
(3) Ɔsom nkwa nna tenten
Wɔ abɔnten so nneɛma mu no, silicone betumi akura adwumayɛ mu mfe pii bere a wɔpaw no yiye na wɔde di dwuma no.
Nanso, ɛnyɛ silicone sealants nyinaa na ɛyɛ wɔn ade yiye wɔ nnua so. Nsonsonoe no fi sɛnea wɔyɛ no ne sɛnea ɛne ne ho hyia no mu.
3. Asiane titiriw no: adhesion a entumi nnyina wɔ nnua so
Nnua nyɛ ade a wɔde hyɛ ase a ɛyɛ pɛ. Wɔ frame koro no ara mu mpo no, ebia wowɔ:
Abɔde mu nnua aburow a ɛsakrasakra
Nneɛma a wɔde kata so anaasɛ varnishes
Ayaresa ahorow a wɔde hyɛ nsu mu
Micro-porosity nsonsonoe
Eyi de asɛnnennen kɛse ba:adhesion a ɛnhyia.
Nneɛma a ɛtaa di huammɔ wɔ nnua mfɛnsere a wɔde hyɛ mu no bi ne:
Sealant peeling fi nneɛma a wɔde akata so
Edge lifting akyi bere mu kankyee
Ntrɛwmu nketenkete a ɛba wɔ ntwea so
Adhesion a ɛyera wɔ mmeae a ɛhɔ yɛ nwini
Mpɛn pii no, sealant no ankasa nyɛ "bɔne"-ɛrentumi nkura nkitahodi a ɛyɛ den mu kɛkɛ wɔ kankyee tebea ankasa mu.
4. Acid cure vs neutral cure: nea enti a ɛho hia kɛse mpo ma nnua
Wɔ nnua mfɛnsere dwumadie mu no, curing nhyehyɛeɛ no di dwuma titire wɔ bere tenten-dwumayɛ mu.
Acid aduru silicone (acetoxy su) .
Mpɛn pii no, wɔnkamfo nkyerɛ sɛ wɔmfa nnua mfɛnsere nyɛ.
Nsɛmpɔw atitiriw:
Ebetumi ne nneɛma a wɔde kata so anaasɛ nnua a wɔayɛ ho adwuma no adi nkitaho
Hua a ano yɛ den bere a wɔde rehyɛ mu no
Asiane a ɛkɔ soro sɛ ɛbɛba sɛ asase ani yɛ ade wɔ baabiara
Ɛnyɛ den koraa wɔ afrafra-nneɛma nkwaa mu
Acid cure systems taa fata yie ma glass anaa ceramic-nko dwumadie, ɛnyɛ nnua frame.
Neutral cure silicone (wɔpɛ sɛ wɔpaw) .
Neutral cure silicone ne gyinapɛn a wɔde yɛ nnua mfɛnsere nhyehyɛe wɔ adwumayɛfo adansi mu.
Nea enti a ɛyɛ adwuma yiye:
Nneɛma a wɔde yɛ acidic by-nneɛma biara nni hɔ
Asiane a ɛwɔ hɔ sɛ ɛbɛsɛe nneɛma a wɔde kata so anaasɛ nea wɔde awie no so tew
Nnua a wɔayɛ ho adwuma a ɛne ne ho hyia yiye
More stable bere tenten-bere adhesion suban
Wɔ abɔnten nnua mfɛnsere adwuma dodow no ara mu no, neutral cure silicone yɛ nea etu mpɔn a ɛyɛ mfitiase nkyerɛkyerɛmu.
5. Nea ɛkyerɛ sɛnea wɔyɛ adwuma wɔ nnua mfɛnsere so ankasa
Wɔ curing nhyehyɛe no akyi no, real-wiase adwumayɛ gyina formulation quality so. Akuw a wɔtɔ nneɛma taa bu wɔn ani gu nneɛma atitiriw yi so:
1. Modulus a ɛba fam-modulus nhyehyɛe
Nnua tu kɔ so tu. Silicone a ɛba fam-modulus betumi atrɛw na ayɛ mia ntɛmntɛm a ɛnhyɛ bond line no so dua.
2. Primer a ɛne ne ho hyia
Nnua a ɛwɔ soro anaa nea wɔde kata so no bi hia primer na ama atumi abata ho denneennen. Wɔayɛ nhyehyɛe a ɛkorɔn-a ɛyɛ adwuma sɛ ɛne primer anaasɛ enni mu a egyina substrate tebea so.
3. UV a ɛma ɛyɛ den
Wɔ abɔnten nnua mfɛnsere fam no, UV a ɛda adi bere nyinaa. UV a entumi nnyina ano yiye no ma:
Nneɛma a ɛwɔ soro a ɛpaapae
Elasticity a ɛyera
Kɔla sesa bere a bere kɔ so no
4. Nsu a wotumi gyina ano bere a wɔreyɛ no yare no
Nnua tumi gyae anaasɛ ɛtwetwe nsu bere a wɔde rehyɛ mu no. Ɛsɛ sɛ silicone nhyehyɛe a ɛyɛ den no gyina nneɛma a atwa yɛn ho ahyia mu nsakrae a ɛkɔ fam ano bere a wɔresa no yare no.
5. Paint ne coating a ɛne ne ho hyia
Wɔ adansi adwuma pii mu no, wɔde adwini anaa wɔde nkekae gu nnua a wɔde ayɛ ntama so. Ɛnsɛ sɛ sealant ma kɔla sesa anaasɛ nnuru ne nneɛma a wɔde kata so no di nkitaho.
6. Installation quality yɛ adwumayɛ ade titiriw
Silicone a ɛkorɔn-grade mpo betumi adi nkogu sɛ wɔanhyɛ instɔlehyɛn no so a.
Afuw mu nsɛm a ɛtaa ba no bi ne:
(1) Nnua a wɔansiesie so a wɔde kata so
Mfutuma, ngo, anaa nneɛma dedaw a wɔde kata so no brɛ nea ɛbata ho no ase kɛse. Ɛsɛ sɛ nnua ani ho tew na ɛyɛ den ansa na wɔde ahyɛ mu.
(2) Nkwaa nhyehyɛe a ɛnteɛ
Ɛsɛ sɛ nnua a wɔde ayɛ mfɛnsere nkwaa ma ɛyɛ nea ɛfata. Sɛ nkwaa no mu nnɔ dodo anaasɛ ɛyɛ teateaa dodo a, nhyɛso boaboa ano wɔ anoano.
(3) Sealant no mu duru a ɛnnɔɔso
Nkwaa a ɛyɛ tratraa ntumi nnye nnua a ɛkeka ne ho wɔ bere bi mu, na ɛma ɛpaapae ntɛm.
(4) Osu anaa nsu a ɛtɔ ntɛm
Ayaresa a edi mũ gye bere. Sɛ wɔda no adi ntɛm dodo a, ebetumi ama sealant no mu nhyehyɛe ayɛ mmerɛw.
7. Sɛnea ɛsɛ sɛ akuw a wɔtɔ nneɛma no susuw silicone a wɔde yɛ nnua mfɛnsere ho
Wɔ adetɔ ho gyinaesi ankasa mu no, ɛnsɛ sɛ wɔde adwene si "generic silicone sealant" so, na mmom ɛsɛ sɛ wɔde adwene si nhyehyɛe no a ɛfata so.
Nhwehwɛmu a wɔde yɛ nhwehwɛmu a mfaso wɔ so no bi ne:
Neutral cure system (ɛyɛ ahyɛde ma nnua dodow no ara a wɔde di dwuma) .
Low-modulus flexibility ma kankyee absorption
Nnua a wɔakata so ne nea wɔmfa nkata so a wɔada no adi sɛ ɛbata ho
UV a ɛko tia a wɔde di dwuma wɔ abɔnten
Nea ɛne paint ne stains hyia
Wɔakyerɛw bere tenten-afuw mu adwumayɛ
Mfiridwuma ho nsɛm nkrataa ne application ho nkyerɛkyerɛmu ankasa taa ho hia sen aguadi ho nsɛm.
8. Baabi a silicone sealant yɛ adwuma yiye wɔ nnua mfɛnsere nhyehyɛe mu
Silicone sealant yɛ nea etu mpɔn kɛse wɔ:
Abɔnten so atwa ho ahyia a wɔde nsɔano atwa nnua a wɔde ayɛ nnua ho ahyia
Glass-kɔ-nnua ntam nkitahodi nkwaa
Ntrɛwmu nkwaa a ɛda nnua ne abo ntam
Wim tebea ho nsɔano wɔ façade window nhyehyɛe ahorow mu
Mfinimfini finishing joints baabi a ɛho hia sɛ wɔyɛ nsakrae
Ɛnyɛ nea ɛfata kɛse mma:
Structural adesoa-asoa bonding
Ntrɛwmu a emu dɔ a enni nneɛma a wɔde gyina akyi
Nnua a srade pii wom anaasɛ entumi nnyina a wɔmfa nnuru nhyɛ mu
Awie
Nnua mfɛnsere de adansi ho mfaso ba, nanso ɛde mmeae a wɔde nsɔano a ɛyɛ den sen biara a ɛwɔ adansi mu no biako nso ba.
Silicone sealant ne adeɛ a wɔtaa de di asɛnnennen yi ho dwuma-nanso nkonimdie gyina paw ne dwumadie a ɛteɛ so kɛseɛ.
Wɔ akuw a wɔtɔ nneɛma ne wɔn a wɔyɛ adwuma wɔ hɔ fam no, ade titiriw a wɔde kɔ no yɛ tẽẽ:
Ɛnyɛ nea ɛdɔɔso sɛ wobɛkyerɛ "silicone sealant ma mfɛnsere."
Wohia nhyehyeɛ a ɛte nnua no kankan, asase ani nsakraeɛ, ne wim tebea a ɛda adi bere tenten-te ase.
Efisɛ wɔ nnua mfɛnsere nhyehyɛe mu no, sealant ntaa mfi ase bere a wɔde ahyɛ mu no.
Efi ase asram pii akyi, bere a mmere mu kankyee fi ase sɔ nkwaa biara a ɛwɔ nhyehyɛe no mu hwɛ no.
