Ukukhethwa kwesivalo sesibili sengilazi yokuvikela umswakama

Ingilazi eyonga amandla yezakhiwo ezifana nezindlu zokuhlala, enesivikelo esihle kakhulu sokushisa kanye nokusebenza kahle kokuvikela umsindo, futhi iyinhle futhi iyasebenza. Isivikelo sengilazi yokuvikela asibali inani elikhulu lezindleko zengilazi yokuvikela, kodwa sibaluleke kakhulu ekuqineni nasekusetshenzisweni okuphephile kwengilazi yokuvikela, ngakho-ke ungayikhetha kanjani?

Mayelana nokuvikela ingilazi

Ingilazi yokuvikela yenziwe ngezingcezu ezimbili (noma ngaphezulu) zengilazi kanye nama-spacer ahlanganiswe ndawonye. Uhlobo lokuvala lusebenzisa kakhulu indlela ye-glue strip kanye nendlela ye-glue joint. Njengamanje, ukuvalwa okuphindwe kabili esakhiweni se-glue joint sealing kusetshenziswa kakhulu. Isakhiwo sinjengoba kuboniswe esithombeni: izingcezu ezimbili zengilazi zihlukaniswe ngama-spacer, i-spacer kanye nengilazi zivalwe nge-butyl glue ngaphambili, kanti ingaphakathi le-spacer ligcwele isihlungo sama-molecule, futhi unqenqema lwengilazi kanye nengaphandle le-spacer kwakheka. Igebe livalwe nge-sealant yesibili.

Izinhlobo ze-sealant yesibili yokuvikela ingilazi

Kunezinhlobo ezintathu eziyinhloko ze-insulating glass secondary sealants: i-silicone, i-polyurethane kanye ne-polysulfide. Kodwa-ke, ngenxa ye-polysulfide, i-polyurethane adhesive inokumelana nokuguga kwe-UV okubi, futhi uma ubuso bokubopha nengilazi buvezwa elangeni isikhathi eside, kuzokwenzeka i-degumming. Uma kwenzeka lesi simo, ishidi langaphandle lengilazi evikelayo yodonga lwekhethini lengilazi olufihliwe lizowa noma ukuvalwa kwengilazi evikelayo yodonga lwekhethini lengilazi olusekelwe iphuzu kuzohluleka. Isakhiwo sama-molecule se-silicone sealant senza i-silicone sealant ibe nezinzuzo zokumelana nokushisa okuphezulu nokuphansi, ukumelana nesimo sezulu kanye nokumelana nokuguga kwe-ultraviolet, futhi ngesikhathi esifanayo, izinga lokumuncwa kwamanzi liphansi, ngakho-ke i-silicone isetshenziswa kakhulu emakethe.

Izingozi Zokusetshenziswa Okungalungile

Izinkinga ezibangelwa ukukhethwa okungafanele kwe-sealant yesibili zingahlukaniswa ngezigaba ezimbili ezilandelayo: esinye ukulahlekelwa umsebenzi wokusetshenziswa kwengilazi yokuvikela, okungukuthi, umsebenzi wokuqala wengilazi yokuvikela ulahlekile; esinye sihlobene nokuphepha kokusetshenziswa kwengilazi yokuvikela— — Okungukuthi, ingozi yokuphepha ebangelwa ukuwa kweshidi langaphandle lengilazi yokuvikela.

Izizathu zokwehluleka kwezivalo zeglasi zokuvikela ukuvikela ngokuvamile yilezi:

Ekuhlonzeni izingozi zekhwalithi yodonga lwekhethini, kutholakala ngokuhlaziya ukuthi kunezizathu ezintathu eziyinhloko zokuwa kwengilazi yangaphandle:

1. Ukuhambisana kwe-sealant yesibili yengilazi yokuvikela;

2. Ukuze kongiwe izindleko, amaqembu afanele aphishekela ngamabomu amanani aphansi, kanti isivali sesibili sokuvikela ingilazi sisebenzisa izivali zesakhiwo ezingezona i-silicone njenge-polysulfide kanye nezivali zokwakha ze-silicone;

3. Abanye abasebenzi bokwakha abanalo ulwazi oluphelele futhi abaqinile, okubangela inkinga yobubanzi bomjovo we-insulating glass sealant yesibili.

Izinyathelo zokuphepha zokukhetha isivalo sesibili

I-sealant yesibili yokuvikela ingilazi inethonya elikhulu kwikhwalithi kanye nokuphila kwenkonzo yengilazi yokuvikela. I-sealant yesakhiwo yokuvikela ingilazi ihlobene ngqo nokuphepha kodonga lwekhethini. Ngakho-ke, akumelwe sikhethe umkhiqizo ofanele kuphela, kodwa futhi sikhethe umkhiqizo ofanele.

Okokuqala, kuyahambisana nezindinganiso futhi kuyafunwa. Okwesibili, ungasebenzisi izinto zokuvala ezigcwele uwoyela. Okokugcina, khetha uhlobo oludumile njenge-junbond
