Iwindi lwezimpawu amawindi plastic

Iwindi seal for plastic iphrofayela izenzo njengoba ukwahlukanisa, ukuvikela ingaphakathi izakhiwo kusuka umsindo zangaphandle, abandayo, ewela phansi, emoyeni, futhi umswakama. Ungayisebenzisa ku emafasiteleni ezakhiwo nganoma iyiphi injongo. Muva nje, izakhamizi izindlu yesimanje kanye amafulethi ngokuya baqala ukufaka amafasitela amasha, kuhluke Ukusebenziseka nokusebenza kusukela nozakwabo yawo yokhuni. Basiza ukunciphisa izindleko bafudumale inkonzo. Kodwa ngokuhamba kwesikhathi, noma iyiphi, ngisho arcade into engase yonakale, bayajabula, nokubuka amawindi plastic. Uphawu gum nezinye izakhi amasistimu yesimanje njalo adinga yesondlo.

incazelo

Iwindi uphawu kuvimbela ingress izinto angangeni emagcekeni. Ngalo ingavikelwa kusuka umswakama nokufakwa, okungase kubuqede. izakhi uphawu babe namandla high, okuyinto ngezinye izikhathi kuqhathaniswa izimfanelo eyinqaba kuya ephekiwe. Sebenzisa lwezimpawu efanayo kungaba in ezahlukene okushisa, okuyinto ziyahlukahluka phakathi -40 futhi +55 ° C. Lezi zici amelana ukusonteka, zingabantu imvelo, futhi ensimini yabo kwesicelo lisabalele. Uma sikhuluma kugcineke, uphawu iwindi ayiqukethe ingxenye izakhi ukuthi kungaba anobuthi. Ukuvakashela esitolo, ungakwazi ukukhetha umbala uphawu, okuzokwenza ukufanisa umthunzi ifremu ifasitela.

izici lobuchwepheshe

Iwindi seal akwazi ukukhonza kuze kube iminyaka engu-30, futhi izinga lokushisa ezisebenza zingahluka ngokuya ubuchwepheshe ukukhiqizwa. Material ngasesinqeni se element akuzona ngakho nozwelo imiphumela we-ozone UV ukukhanya. izici Technical lwezimpawu lemikhiqizo ezahlukene Ungashintsha, ngakho udinga ukukhokhela ukunakekelwa okukhethekile ukuze le nkinga.

Kukhethwa impahla: lwezimpawu injoloba kanye abicah

Ukukhiqiza inqubo iraba uphawu eqala injoloba iqine usebenzisa isibabule ultraviolet. Isakhi esiyinhloko umule izenzo, ungasebenzisa lezi zinto iminyaka engu-30. Lokhu okufana uphawu inikeza uphawu wonke amalunga etholakalayo.

Silicone ilungele akubo bazokhonza lapha iminyaka isikhathi eside kunaleso 10. Ngo womshini lezi zinto asetshenziselwa izinto imvelo ukuthi umbukiso anda ukumelana nokushintshashintsha kwezinga lokushisa. I izakhiwo kungukuthi elahlekile in operation, ngisho noma uhla lokushisa kusuka -40 kuya +150 ° C. Indaba olumelana kwelanga, umoya-mpilo, i-ozone.

EPDM futhi TPE-seal

Iwindi seal for amawindi plastic zingenziwa ethylene propylene. ukuphila inkonzo kulokhu iminyaka engu-20, okokusebenza amelana ejenti emkhathini futhi akusho crack, angasebenzisa ngempumelelo ezinye izinhloso. Lapho elastomers Thermoplastic kuthiwa impahla based, isihloko kuzwakala TPE, lapho impahla liziphatha njengoba iraba, kusekelwe Ushintshe zokwenziwa polymers.

Izici PVC sealant

Iphrofayela iwindi uphawu nge okuyinto kungenzeka ukwehlukanisa ngempumelelo futhi bavikele singenziwa ka polyvinyl chloride, okuyinto kunezinzuzo eziningi futhi inezici ezithile ezingathandeki. Ungasebenzisa kuphela ezindaweni efudumele ezifana yokuhlala, kodwa ukuphila isevisi yeminyaka 3 kuphela. yokukhiqiza ubuchwepheshe ulula ku isizinda analogue, okuyinto kunomphumela omuhle ukubaluleka, okuyinto, ngeshwa, awukwazi ishiwo izinga.

Isidingo esikhundleni uphawu

Elastics amawindi idinga ukushintshwa, uma ubona ukuthi uvele ekamelweni okusalungiswa, ku ingilazi indawo - condensate namawindi ngokwabo baye baqala ukumisa. Ebusweni engaphakathi kungenzeka kanjalo zimiswe frost, okuyinto enomthelela bafake nhlobo noma ngokwengxenye we iraba uphawu. Ukufingqa kungenzeka komyanga lokuvala enezinto, okuholela izinga lokushisa phakathi liyancipha ingilazi, okuphumela ekwakhiweni umswakama.

Kuphethe esikhundleni kophawu

Uma sinqamukile abicah sealant iwindi, walahlekelwa impahla yabo futhi ayisekho ivikela yomsebenzisi, khona-ke kufanele kuthathelwe indawo. Ukuze wenze lokhu, sebenzisa isethi ezithile zokwakha kanye namathuluzi, kufaka:

• sikelo abukhali;
• glue;
• uphawu impahla.

Njengoba nje uphawu wayeneminyaka kungenzeka ukususa, ukuhlanza ezimbotsheni ukungcola, ngoba lokhu ungasebenzisa ibhulashi nokunwebeka. Anemifantu ke wasula ngendwangu emanzi, bese kahle ezomile. Angles ziphathwa nge glue, ukucutshungulwa wenziwa ezindaweni lapho nenkanuko edlulele-material amasha lekufanele akhicitwe. I intambo kufanele kube njengoba yayinjalo, kubalulekile ukuba anqume ngokweqile nge sikelo kanye okuholela ukuxhuma emalungeni, usebenzisa i-glue.

isazi izincomo

Sealers ngokuba zamafasitela akufanele welulela phakathi nokufaka. Gwema kokuba esikhundleni uphawu anganqanda ukulungiswa indlela lokhu esiqokiwe setha imbobo ukhiye bese liphenduka kuze elamukelekile. Uma le ndlela ayikuvumeli ukufeza nomphumela ofiselekayo, isinyathelo sokuqala isuswe Sash, kungcono ukukwenza kusukela lomnyango phezulu. Ngokulandelayo, uphawu ubudala isuswe, bese ukusetha anemifantu entsha, isenzo kufanele kube kancane kancane.

Uma ufaka iraba uphawu iwindi, asikho isidingo sokuba umuntu alahle kokokunamathisela ubudala. Kungcono ukusebenzisa ungqimba entsha. Rush ngalesi nqubo akufanele, kusukela kokokunamathisela kungase smudge. Kufanele ulinde omiswe ephelele ingxube kuphela ngemva casement Kunconywa ukusetha endaweni. Uma ifika lapho ukuze gum elidala engaboshiwe ngokuphelele futhi ingasetshenziswa namanje, kutuswa ukubuyisela uphawu, ngoba ukuthi nivame nge amafutha spray.

esinye isiqondiso ngokuqondene Ukukhetha kophawu

Uma namanje awazi ukuthi iyiphi ukukhetha sealant, kubalulekile ukuba sinake izici ngamunye wabo. Ngokwesibonelo, i-polymer yenziwa of high quality PVC, kodwa has bokwenza njengoba ezifweni okusezingeni eliphezulu ukuba isimo sezulu esibi. Ehlobo lika lokhu uphawu sashintsha futhi kule Uqinisa ebusika, phakathi kwabanye, ikhishelwa elangeni. Kodwa izimvu zamanzi, injoloba kanye iraba kukhona enokwethenjelwa kakhulu futhi enza izinto ezihlukahlukene iyasebenza. Banezimfanelo ukuphikiswa ukuba lokushisa. Ultraviolet seal ezifana engabathinti, zingabantu kakhulu ukumelana ukugqoka. Self-ingcina iwindi gasket singenziwa ka polyethylene Foam. Lokhu kwaziswa lingaphansi ezivamile ngenxa ukhwaliti ongaphakeme futhi ezihlukahlukene elincane amafomu. Silicone kuyinto eqolo, ngakho-ke isebenzisa ukufuneka kakhulu. Indaba abuthonywa weathering, has ukuzinza okusezingeni eliphezulu futhi kuveza kophawu iraba okukhulunywa ukuchayeka imvelo lokukhanda. Ukuvikelwa okuphansi umoya umsindo sici ukungena nakwamanye amazwe EPDM uphawu.

isiphetho

Impilo inkonzo kophawu gum kuzoncika hhayi kuphela izici zangaphandle negative, kodwa futhi ku ukunakekelwa kahle. Ukuze bandise nokuphila isidingo ukuligcina lihlanzekile timphawu iwindi. Ngenxa yale njongo ezifanele uphawu Kwamanzi bahlanza kusuka ukungcola nothuli nivame ne abicah gel. Izenzo ezinjalo kufanele kwenziwe izikhathi eziningana ngonyaka, kuphela ngaphansi kwezimo ezinje gum esikhundleni uzobe kokuchitha ingasaphathwa.
