I-Silicone sealant yinto ebalulekileyo yokuncamathelisa, ikakhulu esetyenziselwa ukudibanisa iiglasi ezahlukeneyo kunye nezinye ii-substrates. Isetyenziswa ngokubanzi kubomi bentsapho, kwaye kukho iintlobo ezininzi ze-silicone sealants kwimarike, kwaye amandla ebhondi ye-silicone sealants iboniswa ngokubanzi. Ngoko, indlela yokusebenzisa i-silicone sealant? Kuthatha ixesha elingakanani ukunyanga i-silicone sealant?
Amanyathelo okusetyenziswa kwe-silicone sealant
1.Susa ukufuma, igrisi, uthuli kunye nezinye izinto ezingcolisa umphezulu wezinto. Xa kufanelekile, sebenzisa isinyibilikisi (njengexylene, butanone) ukucoca umphezulu, uze usebenzise iragi ecocekileyo ukosule zonke iintsalela ukuze ucoceke kwaye wome ngokupheleleyo.
2.Ngqubuthela umphezulu okufutshane nojongano ngeteyiphu yeplastiki. Ukuqinisekisa ukuba umgca womsebenzi wokutywina ulungile kwaye ucocekile.
3.Sika umlomo wombhobho wokutywina uze ufakele umbhobho womlomo otsolo. Emva koko ngokobungakanani be-caulking, inqunywe kwi-45 ° Angle.
4.Faka i-glue gun kwaye ucinezele izinto zeglue ecaleni kwe-gap kwi-45 ° Angle ukuqinisekisa ukuba izinto zeglue zidibene ngokusondeleyo kunye nomgangatho wesiseko. Xa ububanzi bomthungo bukhulu ngaphezu kwe-15 mm, i-gluing ephindaphindiweyo iyafuneka. Emva kokudibanisa, nciphisa umphezulu ngommese ukuze ususe iglue engaphezulu, uze ukrazule i-tape. Ukuba kukho amabala, zisuse ngelaphu elimanzi.
I-5.i-sealant kwiqondo lobushushu begumbi emva kwemizuzu eyi-10 ye-vulcanization yomhlaba, i-vulcanization epheleleyo ithatha iiyure ezingama-24 okanye ngaphezulu, ngokobunzima bengubo kunye nobushushu kunye nokufuma kwendalo.
Ixesha lokunyanga i-silicone sealant
Ixesha lokunamathela kwe-silicone sealant kunye nexesha lokunyanga:
Inkqubo yokunyanga i-Silicone sealant iphuhliswa ukusuka kumphezulu ukuya ngaphakathi, iimpawu ezahlukeneyo ze-sealant surface eyomileyo kunye nexesha lokunyanga azifani, ngoko ke ukuba ufuna ukulungisa umphezulu kufuneka uqhutywe ngaphambi kokuba indawo yesitywina yome. Phakathi kwazo, iglu yeasidi kunye neglu engathathi hlangothi esobala kufuneka ngokubanzi ibe phakathi kwemizuzu emi-5 ukuya kwe-10, kunye neglu engathathi hlangothi yombala ongathathi hlangothi kufuneka ibe phakathi kwemizuzu engama-30. Ukuba iphepha lokwahlula umbala lisetyenziselwa ukugubungela indawo ethile, emva kokufaka iglue, kufuneka isuswe ngaphambi kokuba ulusu lwenziwe.
Ixesha lokunyanga i-silicone sealant (kwiqondo lokushisa kwe-20 ° kunye nomswakama we-40%) landa ngokunyuka kobunzima bokubambisana. Umzekelo, i-12mm engqingqwa ye-acid silicone sealant inokuthatha iintsuku ezi-3-4 ukuseta, kodwa ngaphakathi kweeyure ezingama-24, umaleko wangaphandle we-3mm uphilisiwe. Ukuba indawo apho i-sealant isetyenziswe ngokuyinxenye okanye ivalwe ngokupheleleyo, ngoko ixesha lokunyanga lichongwa ngokuqiniswa kwesitywina. Kwiimeko ezahlukeneyo zokudibanisa, kubandakanywa iimeko zomoya, umphumo wokudibanisa kufuneka uhlolwe ngokupheleleyo ngaphambi kokuba kusetyenziswe izixhobo ezidibeneyo. Unyango luya kuncipha kumaqondo obushushu asezantsi (ngaphantsi kwe-5 °) kunye nokufuma (ngaphantsi kwe-40%).
