Umehluko kanye nokusetshenziswa okuqondile kwe-sealant, i-glass sealant kanye ne-structural sealant

I-Glass sealant

 

I-Glass sealant yinto esetshenziselwa ukuhlanganisa nokuvala izinhlobo ezahlukene zengilazi nezinye izinto eziyisisekelo.Ihlukaniswe ikakhulukazi izigaba ezimbili: i-silicone sealant ne-polyurethane sealant (PU).I-Silicone sealant ihlukaniswe yaba i-asidi sealant, i-neutral sealant, i-structural sealant, njll. I-polyurethane sealant ihlukaniswe yaba i-adhesive sealant ne-sealant.

 

Izicelo eziqondile ze-glass sealant

 

1.Ifanele ukuvaleka okungamelana nesimo sezulu kwezindonga zamakhethini ahlukahlukene, okunconyelwe ikakhulukazi ukuvala amakhethini engilazi ukumelana nesimo sezulu, izindonga zamakhethini zephaneli ye-aluminium-plastic, namatshe alengayo omile.

2. Ukuvalwa komthungo phakathi kwensimbi, ingilazi, i-aluminium, amathayela e-ceramic, ingilazi yemvelo nengilazi eboshwe.

 

3. Ukuvalwa okuhlanganyelwe kukakhonkolo, usimende, amatshe, amatshe, imabula, insimbi, ukhuni, i-aluminiyamu ene-anodized kanye nezindawo ezipendiwe ze-aluminium.Ezimweni eziningi asikho isidingo sokusebenzisa i-primer.

 

4. Inokumelana nesimo sezulu esihle kakhulu njengokumelana ne-ozone nokumelana ne-ultraviolet, futhi inempilo ende yesevisi.

 

Isingeniso se-Sealant

 

I-Sealant isho into yokuvala ewohloka ngokuma kwendawo yokuvala, akulula ukugeleza, futhi inamandla athile okunamathela.Ngokuvamile kusekelwe ezintweni ezomile noma ezingakomisi ze-viscous ezifana ne-asphalt, inhlaka yemvelo noma i-resin yokwenziwa, irabha yemvelo noma irabha yokwenziwa, bese yengeza ama-inert fillers, alandelwa ama-plasticizers, ama-solvents, ama-ejenti okwelapha, ama-accelerator, njll. Ilinde ukukhiqizwa .Ama-sealants ahlukaniswa ngokusebenza.Umsebenzi wabo kuphela ukuhlanganisa.I-sealant evikela isimo sezulu, i-silicone structural sealant, ne-polyurethane sealant zonke zinemisebenzi yokuvala, kodwa futhi zineminye imisebenzi ebaluleke kakhulu, njengamandla okubopha okuphezulu kanye nokumelana nesimo sezulu esihle.

 

Ukusetshenziswa okuqondile kwama-sealants

 

1. Ngokusho kwezigaba, zingahlukaniswa zibe i-sealant yokwakha, i-automobile sealant, i-insulation sealant, i-packaging sealant, i-mining sealant nezinye izinhlobo.

 

2. Ngokwesigaba ngemva kokwakhiwa, ingahlukaniswa ibe i-curred sealant kanye ne-semi-cured sealant.Ama-sealant alashiwe angahlukaniswa abe ama-sealant aqinile nama-flexible sealants.I-Rigid sealant iqinile eyakheka ngemva kokwenziwa i-vulcanization noma ukuqina.Inokuqina okuncane, ayikwazi ukugoba, futhi ngokuvamile ilunga alikwazi ukunyakaza;i-flexible sealant iyanwebeka futhi ithambile ngemva kokwenziwa vulcanization.I-sealant engapholi iyisici esipholile esigcina i-tackifier engomisi futhi siqhubeke sithuthela phezulu ngemva kokufakwa.

 

 

I-Sealant yesakhiwo

 

I-structural sealant inamandla aphezulu (amandla acindezelayo>65MPa, amandla e-steel-to-steel positive tensile bonding>30MPa, shear strength>18MPa), ingakwazi ukumelana nemithwalo emikhulu, imelana nokuguga, ukukhathala, nokugqwala, futhi isebenza kahle ngaphakathi. ukuphila kwayo okulindelekile.I-adhesive ezinzile ifanele ukubopha izingxenye zesakhiwo ezingamelana namandla aqinile.

 

1. Ikakhulu isetshenziselwa amadivaysi okuhlanganisa esakhiwo noma okungezona ezakhiwe phakathi kwensimbi yodonga lwamakhethini engilazi kanye nengilazi.

 

2. Ingilazi ingaxhunywa ngokuqondile ebusweni bezingxenye zensimbi ukuze yenze ingxenye eyodwa yomhlangano ukuze ihlangabezane nezidingo zokuklama kohlaka olufihleke ngokugcwele noma izindonga zamakhethini ezifihliwe kancane.

 

3. Ukuhlanganiswa kwesakhiwo nokuvalwa kwengilazi yokuvikela.

 

4. Ifanele ukubopha, ukugoqa kanye nokubekwa uphawu kwetshe elinezimbotshana, ingilazi elaminethiwe, ingilazi yokuvikela, ingilazi yesibuko, ingilazi eboshwe, i-zinc, ithusi, insimbi nezinye izinto.
