Iyini i-neutral silicone sealant yesimo sezulu?
Impendulo:
I-Neutral silicone weatherproof sealant iyisici esisodwa -, i-neutral organic silicone sealant enokumelana nesimo sezulu esihle kakhulu, ukunwebeka, ukunamathela kanye nezinto ezilwa - nokuguga. Ngemva kokuphulukisa, yakha i-colloid eguquguqukayo futhi ifaneleka i-caulking, i-sealing kanye ne-bonding emikhakheni efana nokwakhiwa, ukuhlobisa kanye nezimoto.
Uyini umehluko phakathi kwe-silicone sealant engathathi hlangothi kanye ne-acidic sealant?
Impendulo:
I-Acidic sealant: Ikhulula i-acetic acid ngesikhathi sokwelashwa, engagqwalisa izinto ezifana nezinsimbi nosimende. Nokho, iyelapha ngokushesha futhi inenani eliphansi uma kuqhathaniswa.
I-Neutral sealant: Ayikhiphi izinto ezibolayo ngesikhathi sokwelashwa, iphephe kakhudlwana ezintweni eziningi (njengengilazi, insimbi, ipulasitiki), futhi inohlu olubanzi lwezinhlelo zokusebenza. Kodwa isikhathi sayo sokuphulukisa sithe ukudlula.
Yiziphi izimo ezifanele i-neutral silicone weatherproof sealant?
Impendulo:
I-caulking yokwakha (njengamalunga eminyango, amafasitela nezindonga zamakhethini).
Ukuhlanganisa nokubeka uphawu kwezinto ezifana nengilazi, i-aluminium namatshe.
Ayizifanele izindawo lapho icwiliswa khona emanzini isikhathi eside noma ichayeke emazingeni okushisa aphakeme kakhulu (njengangaphezu kuka-150 degree).
Kuthatha isikhathi esingakanani ukwelapha?
Impendulo:
Tack - isikhathi samahhala: Cishe imizuzu engama-30 ukuya ehoreni elingu-1 (ifilimu iyamafomu phezulu).
Ukwelapha ngokugcwele: Ngokuvamile kuthatha amahora angu-24 - 72 (kuthintwa izinga lokushisa, umswakama kanye nogqinsi lwesendlalelo sokunamathela).
Ithiphu: Gwema ukuthintana namanzi noma i-extrusion yamandla yangaphandle phakathi nenqubo yokwelapha.
Indlela yokwakha ngendlela efanele?
Impendulo:
Hlanza ingaphezulu le-substrate ukuze uqiniseke ukuthi awekho amafutha, uthuli kanye nomswakama.
Sebenzisa isibhamu se-caulking ukuze usebenzise i-sealant ngokulinganayo ukuze ugcwalise igebe.
Sebenzisa i-spatula noma umunwe weglavu ukuze ubhebhezele i-colloid ukuze uqiniseke ukuthi ihlangene.
Gwema ukuthinta noma ukuhambisa izingxenye ngaphambi kokwelapha.
Ingabe ihambisana nemvelo futhi ayinangozi?
Impendulo:
Ithobelana namazinga kazwelonke (afana ne-GB/T 14683 - 2017) futhi ayiqukethe izinto eziyingozi njenge-formaldehyde ne-benzene. Kodwa-ke, kunconywa ukufaka umoya ngesikhathi sokwakhiwa futhi ugweme ukuthintana ngqo nesikhumba noma amehlo.
Liyini ibanga lokumelana nezinga lokushisa?
Impendulo:
Ngokuvamile kuba ngu-- 50℃kuya ku-150℃, futhi eminye imikhiqizo ephezulu - yokusebenza ingafinyelela ku-200℃. Ezindaweni zokushisa eziphakeme zesikhathi eside - -, ama-sealant akhethekile amelana nezinga lokushisa - - kufanele akhethwe.
Indlela yokugcina?
Impendulo:
Akuvuliwe: Gcina endaweni epholile neyomile (5 - 30℃), futhi impilo yeshalofu ngokuvamile iyizinyanga eziyi-12.
Ivuliwe: Vala umlomo we-sealant futhi uyisebenzise ngokushesha ngangokunokwenzeka (phakathi nenyanga engu-1).
Yiziphi izizathu ezingenzeka zokwehluleka kwesibopho?
Impendulo:
Ubuso be-substrate abuhlanzwa noma bumanzi.
I-colloid igcizelelwa noma ihlangana namanzi ngaphambi kokuba ilapheke ngokuphelele.
Izinto ezisetshenziswayo azihambisani (isibonelo, amanye amapulasitiki adinga ama-sealant akhethekile).
Indlela ukususa sealant ngokweqile?
Impendulo:
Uma ingelapheki: Sula ngendwangu emanzi.
Ngemva kokwelapha: Khipha ngokucophelela nge-blade noma ncibilikisa ngesicoci esikhethekile se-silicone sealant.
Yiziphi izinketho zombala ezitholakalayo?
Impendulo:
Imibala evamile ihlanganisa okukhanyelayo, okumhlophe, okumnyama, okumpunga, njll. Amanye amamodeli asekela imibala yangokwezifiso.
