Isivali sengilazi
I-Glass sealant iyinto esetshenziselwa ukubopha nokuvala izinhlobo ezahlukene zengilazi nezinye izinto eziyisisekelo. Ihlukaniswe kakhulu ngezigaba ezimbili: i-silicone sealant kanye ne-polyurethane sealant (PU). I-Silicone sealant ihlukaniswe ibe yi-acid sealant, i-neutral sealant, i-structural sealant, njll. I-Polyurethane sealant ihlukaniswe ibe yi-adhesive sealant kanye ne-sealant.
Ukusetshenziswa okuqondile kwe-glass sealant
1.Ilungele ukuvalwa kwezindonga ezahlukene zamakhethini okumelana nesimo sezulu, ikakhulukazi inconywa ukuvalwa kwezindonga zamakhethini engilazi okumelana nesimo sezulu, izindonga zamakhethini ephaneli ye-aluminium-plastic, kanye netshe elilenga elomile.
2. Ukuvala ngomthungo phakathi kwensimbi, ingilazi, i-aluminium, amathayili e-ceramic, ingilazi yemvelo kanye nengilazi embozwe ngendwangu.
3. Ukuvalwa okuhlangene kwekhonkrithi, usimende, ukwakhiwa ngamatshe, idwala, imabula, insimbi, ukhuni, i-aluminiyamu e-anodized kanye nezindawo ze-aluminiyamu ezipendiwe. Ezimweni eziningi asikho isidingo sokusebenzisa i-primer.
4. Inokumelana okuhle kakhulu nesimo sezulu njengokumelana ne-ozone kanye nokumelana ne-ultraviolet, futhi iphila isikhathi eside.
Isingeniso se-Sealant
I-Sealant ibhekisela ezintweni zokuvala eziwohloka ngesimo sobuso bokuvala, okungelula ukuzigeleza, futhi zinamandla athile okunamathela. Ngokuvamile zisekelwe ezintweni ezomile noma ezingomi njenge-asphalt, i-resin yemvelo noma i-resin yokwenziwa, irabha yemvelo noma irabha yokwenziwa, bese zengeza ama-inert fillers, kulandelwe ama-plasticizer, ama-solvents, ama-curing agents, ama-accelerator, njll. Zilinde ukukhiqizwa. Ama-Sealant ahlukaniswa ngokusebenza kwawo. Umsebenzi wawo kuphela ukuvala. I-sealant engamelana nesimo sezulu, i-silicone structural sealant, kanye ne-polyurethane sealant konke kunemisebenzi yokuvala, kodwa futhi kuneminye imisebenzi ebaluleke kakhulu, njengokuqina okuphezulu kokubopha kanye nokumelana okuhle nesimo sezulu.
Ukusetshenziswa okuqondile kwama-sealant
1. Ngokusho kwesigaba, ingahlukaniswa ibe yi-building sealant, i-automobile sealant, i-insulation sealant, i-packaging sealant, i-mining sealant nezinye izinhlobo.
2. Ngokwesigaba ngemva kokwakhiwa, ingahlukaniswa ibe yi-sealant elungisiwe kanye ne-sealant elungisiwe kancane. Ama-sealant alungisiwe angahlukaniswa abe yi-sealant eqinile kanye ne-sealant eguquguqukayo. I-sealant eqinile iyi-solid eyakheka ngemva kwe-vulcanization noma ukuqina. Ayina-elasticity encane, ayikwazi ukugoba, futhi ngokuvamile i-joint ayikwazi ukuhamba; i-sealant eguquguqukayo iyanwebeka futhi ithambile ngemva kwe-vulcanization. I-sealant engakhiphi i-sealant ethambile egcina i-tackifier yayo engomi futhi iyaqhubeka nokuthuthela phezulu ngemva kokusetshenziswa.
Isivali sesakhiwo
I-sealant yesakhiwo inamandla aphezulu (amandla okucindezela> 65MPa, amandla okubopha okuthambekelayo kusuka ensimbini kuya ensimbini> 30MPa, amandla okusika> 18MPa), ingamelana nemithwalo emikhulu, imelana nokuguga, ukukhathala, nokugqwala, futhi isebenza kahle phakathi nesikhathi sayo sokuphila esilindelekile. I-adhesive eqinile ifanelekela izingxenye zesakhiwo zokubopha ezingamelana namandla aqinile.
1. Isetshenziswa kakhulu kumadivayisi okubopha angewona awesakhiwo noma angawesakhiwo phakathi kwensimbi yodonga lwekhethini lengilazi nengilazi.
2. Ingilazi ingaxhunywa ngqo ebusweni bezingxenye zensimbi ukuze kwakhiwe ingxenye eyodwa yokuhlangana ukuze kuhlangatshezwane nezidingo zomklamo wohlaka olufihliwe ngokuphelele noma izindonga zamakhethini ohlaka olufihliwe kancane.
3. Ukubopha nokuvala ingilazi evikela ugesi ngesakhiwo.
4. Ifanele ukubopha, ukufaka i-caulking kanye nokuvala itshe elinezimbobo, ingilazi elaminethiwe, ingilazi yokuvikela, ingilazi yesibuko, ingilazi embozwe nge-coated, i-zinc, ithusi, insimbi nezinye izinto.
