UKUBUKEZWA KONKE
Ukukhethwa okulungile kwe-sealant kufanele kucabangele inhloso yejoyinti, usayizi we-joint deformation, ubukhulu bejoyinti, i-joint substrate, imvelo lapho oxhumana nabo abahlanganyeli behlangene, kanye nezakhiwo zemishini i-sealant edingekayo ukuze kuzuzwe. . Phakathi kwabo, ubukhulu bokuhlanganyela bunqunywa uhlobo lokuhlangana kanye nobukhulu obulindelekile bokuguqulwa okuhlangene.
Ukuqinisekisa impilo yesevisi ephelele kanye nokusebenza kwe-sealant, ukukhethwa okulungile kwe-sealant kufanele kucatshangelwe ngokucophelela. Ngokuvamile, izinyathelo ezintathu zingathathwa ukuze kuqinisekiswe ukuthi i-sealant ifinyelela impilo yayo yokuklama efanele.
- 1. Dizayina ama-seams ngokwesayensi nangokunengqondo ngokwezidingo zokusetshenziswa nendawo;
- 2. Thola izinkomba zokusebenza okudingeka i-sealant ihlangabezane nazo kusixhumi esibonakalayo esiklanyelwe;
- 3. Ngokusekelwe ezinkomba zokusebenza ezinqunyiwe, kunconywa ukuba ukhethe i-adhesive futhi uqhube ukuhambisana okudingekayo nokuhlolwa kokunamathela ukuze kuqinisekiswe ukuthi umkhiqizo okhethiwe uhlangabezana nezidingo.
Ama-sealant okwakhiwa enza imisebenzi emithathu elandelayo ngenqubo yokuhlanganisa:
- 1. Iyakwazi ukugcwalisa igebe phakathi kwama-substrates amabili noma ngaphezulu ukuze kwakheke uphawu:
- 2. Ukwakha umgoqo ngokusebenzisa izakhiwo zayo ezibonakalayo nokunamathela ku-substrate
- 3. Gcina ukuqina kokuvala ngaphansi kwesikhathi sokuphila esilindelekile, izimo zokusebenza, nendawo ezungezile.
Izici eziyinhloko ezinquma umsebenzi we-sealant zihlanganisa amandla ayo okunyakaza, izakhiwo zemishini, ukunamathela, ukuqina, nokubukeka. Izakhiwo zemishini nezomshini ikakhulukazi zibhekisela ezinkomba ezinjengokuqina, i-elastic modulus, amandla aqinile, ukumelana nezinyembezi, ukuqina, kanye nezinga lokululama lokunwebeka. Lapho ufaka i-sealant, izidingo zokusetshenziswa eziyinhloko okufanele zicatshangelwe isikhathi samahhala, isikhathi sokubopha, ukuhlehla, impilo yeshalofu (yezinto ezinamathelayo ezinezingxenye ezimbili), ukunwebeka, isivinini esijulile sokuphulukisa, ukungakhihli amagwebu, izindleko, umbala, kanye nokuncipha komugqa phakathi ukwelapha; Ngesikhathi esifanayo, kuyadingeka ukucabangela izakhiwo zokuguga ze-sealant, okuhlanganisa ukumelana kwayo nemisebe ye-UV, izakhiwo zokushisa eziphakeme neziphansi, i-thermal hydrolysis, ukuguga okushisayo, nokumelana ne-oxidation.
Ukunamathela kuyinqubo ehlanganisa ukulungiswa, ukufaka, ukuphulukisa, nokugcinwa kwe-sealant. Ikhwalithi yokusebenza kwe-adhesive ihlobene ngokuqondile nempahla yokubopha, i-sealant, nenqubo yokunamathela. Ngakho-ke, lapho kwenziwa ukwakha, ithonya lezici ezintathu kufanele licatshangelwe ngokuphelele. Kuphela ngokulungisa lezi zici ezintathu ngokunengqondo futhi uzihlanganise ngokwemvelo kungafinyelelwa ukunamathela okuhle, futhi noma iyiphi inkinga kunoma iyiphi isixhumanisi ingaholela ekuhlulekeni kokunamathela.
I-Silicone sealant esetshenziswa ekwakhiweni ihlinzeka ngokuvala uphawu kokumelana nesimo sezulu kanye nokuvala uphawu kwesakhiwo. Ngaphezu komklamo omuhle wesixhumi esibonakalayo, imininingwane yenqubo yokwakha ehambisanayo kufanele futhi ilandelwe phakathi nenqubo yokwakha.
Kunezidingo ezinhlanu eziyisisekelo zokwelashwa okufanele kwendawo yokuhlangana kanye ne-gluing:
- I-interface kufanele ihlanzeke, yome, ingabi nothuli nesithwathwa;
- Uma i-primer idingeka, kufanele isetshenziswe endaweni ehlanzekile;
- Sebenzisa izinto zokubuyela emuva noma i-adhesive tape njengoba kudingeka;
- Uma usebenzisa i-sealant, kuyadingeka ukugcwalisa igebe le-interface nge-sealant;
- Ukuklwebha ukuqinisekisa ukuthi ama-seams abushelelezi, ukuma okulungile, nokuxhumana okuphelele ne-substrate.
I-Silicone sealant nayo ingabhekwa njenge-adhesive ngenxa yesakhiwo sayo samakhemikhali. Ukunamathela kokuvala uphawu kwe-silicone kuwukusabela kwamakhemikhali emvelo, ngakho-ke izinyathelo ezifanele zokusebenzisa zibaluleke kakhulu. Ngenxa yokusetshenziswa kwe-OLIVIA silicone sealant ezindaweni nasezifundeni eziningi ezahlukene, imininingwane yenqubo yokwakha ayikwazi ukuthathwa njengohlelo oluphelele noluphelele lokuqinisekisa ikhwalithi. Ukuphathwa kwekhwalithi yokwakha kufanele kwenziwe, futhi ukuhlolwa kwe-adhesive endaweni kufanele kwenziwe ukuze kuqinisekiswe amandla amahle okunamathela futhi kuqinisekiswe noma yiziphi iziphakamiso mayelana nokunamathela.
Ekulawulweni kwekhwalithi yokwakhiwa kwe-sealant, ukunamathela kanye nokuhambisana kwe-sealant nesisekelo sezinto kufanele kucatshangelwe, okuhlanganisa induku esekelayo, i-tape strip enezinhlangothi ezimbili nezinye izinto ezisizayo. Ukuze kuthuthukiswe ukusebenza okuphezulu kwe-silicone sealant, kuyadingeka ukukhetha ama-silicone sealant ahlukene ngokusekelwe ezindaweni ezahlukene zokwakha, izidingo, nezinto zokwakha, kanye namasu okwakha asezingeni eliphakeme. Izindlela zokwakha ezingajwayelekile zivame ukunciphisa ukusebenza okuphezulu kwama-sealant, njengokuhlanza ubuso be-substrate, inani le-primer elisetshenzisiwe, isilinganiso esingafaneleki se-aspect ratio, ukuxuba okungalingani kwezingxenye ezimbili ze-sealants, kanye nokusetshenziswa kwezihlanzi noma izindlela zokuhlanza ezingalungile, ezingathinta. ukunamathela kwama-sealant futhi kuholele ekuhlulekeni kokunamathela, njengokukhetha okunamathiselwe okungafanele okuholela kumabhamuza kanye nokushintsha kombala kwe-sealant. Ngakho-ke ukukhethwa kwe-sealant kanye nokunemba kwenqubo yokwakha kubalulekile. Ngokwethula le misebenzi, kungasiza ukukhetha uphawu olufanele ngokufanele.
I-Seal engenamanzi kanye ne-Weatherproof
Amanye ama-non-silicone sealants athambekele ekugugeni ngokuhamba kwesikhathi nangaphansi kwethonya lezinto eziyingozi endaweni, ikakhulukazi ngaphansi kwemisebe ye-ultraviolet. Ngakho-ke, lapho ukhetha i-sealant, impilo yesevisi ye-sealant kufanele icatshangelwe. Ukuvalwa kwamanzi okungenamanzi kusetshenziselwa ukugcwalisa izikhala phakathi kwezinto zokuvimbela umoya, imvula, uthuli, njll. Ngakho-ke, i-sealant kufanele ihambisane ngokugcwele ne-substrate, ukuze ikwazi ukunqoba izinguquko ngobukhulu obuhlangene obubangelwa ukunyakaza kwe-substrate ngesikhathi sokwandiswa noma ukucindezela. I-OLIVIA silicone sealant inokumelana okuhle kwe-UV, ingagcina imodulus ecishe ibe njalo, futhi ukunwebeka kwayo akushintshi phakathi kwezinga lokushisa elingu--40 ℃ ukuya ku-+150 ℃.
Ama-sealant aphansi asetshenziswa kakhulu ukugcwalisa izikhala ngaphansi kwezimo eziyisisekelo ezimile ukuvimbela ukungena kothuli, imvula nomoya. Kodwa-ke, ukuncipha ngokweqile, ukuqina ngokuhamba kwesikhathi, nokunamathela okungalungile kungathinta ukusebenza kwabo. Ukuhambisana, ukunamathela, kanye nemiphumela yamakhemikhali kufanele kucatshangelwe uma uzisebenzisa.
Seal Sesakhiwo
I-sealant esetshenziselwa ukuvalwa kwesakhiwo inamathela kakhulu ezinhlotsheni ezimbili zama-substrates. Ngesikhathi esifanayo, ingakwazi ukunqoba ukucindezeleka okuhlangene: ukucindezeleka nokucindezeleka kokucindezela, ukucindezeleka kwe-shear. Ngakho-ke, ngaphambi kokubekwa uphawu, amandla esakhiwo salezi zihlanganisi kufanele aqinisekiswe, ukuze aboniswe ngobuningi lapho kubalwa izidingo zobunjiniyela. Amandla esakhiwo avezwa ngokuya nge-modulus namandla okuqina. Ama-sealant esakhiwo adinga ukufinyelela ezingeni elithile lamandla. Esinye isimo esibalulekile sokubekwa uphawu kwesakhiwo ukuthi ukuhlangana phakathi kophawu ne-substrate akulimazi ngokuhamba kwesikhathi. I-OLIVIA i-silicone structural sealants inokusebenza okuthembekile, impilo ende yesevisi, futhi ifanele ukuvalwa kwesakhiwo.
Izinyathelo Zokuqaphela Ukukhetha I-Silicone Sealant Yokwakhiwa
Ukukhethwa okulungile kwe-sealant akubandakanyi nje kuphela ukukhetha izinto ezinezici ezibonakalayo nezamakhemikhali ezifanele, kodwa futhi kucubungula uhlobo nezakhiwo ze-substrate yokuvala, idizayini ehlanganyelwe (okuhlanganisa ukwesekwa noma izinto ezishunyekiwe), ukusebenza okulindelekile, izidingo zokukhiqiza, kanye nezindleko zokonga. izindleko, zonke zicatshangelwa. Uhlu olulandelayo luvame ukusetshenziswa embonini yezokwakha ukukhetha ama-sealants.
