Ulwazi olusisiseko lwe-silicone sealants

1. Ukuhlelwa:

I-Silicone sealant inokwahlulwa ibe ngamacandelo amabini ukusuka kwipakethe yemveliso: icandelo elinye kunye necandelo ezimbini. Ukunyangwa kwe-silicone sealant ye-single-component kubangelwa utshintsho kwiimpawu ezibonakalayo ngenxa yokudibanisa nomswakama emoyeni;

I-silicone sealant yamacandelo amabini ithetha ukuba iglue ye-silicone yahlulwe yangamaqela amabini, A kunye no-B. Akukho qela linokuqina ukuba likhona lodwa. Kodwa xa iiseti ezimbini zeglue zixutywe, ziyaqina.

Okwangoku, eyona nto ixhaphake kakhulu kwiimarike i-silicone sealant ye-single-component .

I-Acid silicone sealant isetyenziselwa ikakhulu ukudibanisa ngokubanzi phakathi kweglasi kunye nezinye izinto zokwakha. Iglu engathathi hlangothi iyoyisa iimpawu zeglue yeasidi eyonakalisa izinto zetsimbi kwaye isabela ngezinto zealkaline, ngoko inoluhlu olubanzi lwezicelo kwaye ixabiso layo lentengiso liphezulu kancinci kuneglue yeasidi.

Uhlobo olukhethekileyo lweglue yeglasi kwimarike yi-silicone structural sealant. Ngenxa yokuba isetyenziselwa ngokuthe ngqo kwisakhiwo sentsimbi kunye neglasi okanye indibano engeyiyo i-structural bonding yeendonga zeglasi, iimfuno zomgangatho kunye nomgangatho wemveliso zezona ziphezulu phakathi kweeglues zeglasi. Ixabiso lemarike nalo liphezulu.

2. Injongo

(1) I-Acid silicone sealant (umzekelo Iphosa 733)

① Ilungele ukutywinwa, ukubhloka, ukunqanda ukuvuza kunye neenjongo zokumelana nomoya. Ilungele ukusetyenziswa kwangaphakathi nangaphandle (umphumo wangaphakathi ungcono), kwaye i-anti-seepage kunye ne-leak-proof effect iyamangalisa.

② Ukudityaniswa kwemihombiso eyahlukeneyo yangaphakathi yeemoto, kubandakanya: intsimbi, amalaphu kunye namalaphu endalo kunye neeplastiki.

③ Ukubandakanya iigaskithi kwisixhobo sokufudumeza kunye nokupholisa.

④ Faka iimbambo ngaphandle kwemingxuma yezikrufu, iipleyiti zegama kunye nepeyinti kunye nezixhobo zeplastiki kumphezulu wentsimbi.

⑤ Vala iifestile kucango lwe-oveni, umbhobho, iindawo ezidityanisiweyo zemibhobho, kunye neengcango zokungena kwizixhobo zegesi.

⑥ Ukubonelela ngeegaskets ezivuzayo ezenziwe ngoko nangoko kwiibhokisi zegiya, iicompressor, kunye neempompo.

⑦ Vala ikhabhinethi kunye neefestile.

⑧ Ukutywinwa kweefestile zenqwelwana kunye nekhabhi yelori.

⑨ Izixhobo zebhondi kunye nokutywina.

⑩ Yenza isambatho esichasene nokunxiba.

11 Ilamination yentsimbi ebhityileyo efakwe ngaphakathi kwaye izaliswe yinyani, uthungelwano lombhobho kunye nesingxobo sezixhobo.

(2) Isitywina se-silicone esinganyangekiyo kwimozulu ephakathi ( Iphosa 789)

① Ilungele ukutywinwa okuxhathisa imozulu kwiindonga ezahlukeneyo zekhethini, zicetyiswa ngakumbi ukutywinwa okuchasene nemozulu yeendonga zeglasi yomkhusane, i-aluminiyam-yeplastiki yeeplanga zamakhethini amadonga, kunye nelitye elijingayo elijingayo;

② Ukutywinwa komthungo phakathi kwentsimbi, iglasi, ialuminiyam, iithayile zeceramic, iglasi ephilayo, kunye neglasi egqunyiweyo;

③ Ukutywinwa komthungo kwikhonkrithi, isamente, ilitye, ilitye lenyengane, intsimbi, umthi, ialuminiyam ene-anodized kunye nemiphezulu epeyintiweyo yealuminiyam. Kwiimeko ezininzi akukho mfuneko yokusebenzisa i-primer.

(3) Isincamathelisi seSilicone sesakhiwo (Iphosa 793)

① Isetyenziswa ikakhulu kwizixhobo ezidityanisiweyo ezingeyolwakhiwo phakathi kwentsimbi kunye neglasi yeendonga zeglasi yomkhusane.

② Inokudibanisa ngokuthe ngqo iglasi kumphezulu wamacandelo esinyithi ukwenza icandelo lendibano enye, ukuhlangabezana neemfuno zokuyilwa kweendonga zekhethini ezinezakhelo ezifihlakeleyo ngokupheleleyo okanye ezifihlakeleyo.

③ Ukudityaniswa kolwakhiwo kunye nokutywinwa kweglasi yokugquma.

3. Izithintelo

Zonke iintlobo ze-silicone sealant ziphantsi kwezithintelo zilandelayo xa zisetyenziswa:

① Ayifanelekanga ukwakhiwa kwiindawo ezifakwe emanzini ixesha elide;

② Ayihambelani nezixhobo eziza kuvuza igrisi, iiplastiki okanye izinyibilikisi;

③ Ayinakusetyenziswa kwindawo eneqabaka okanye emanzi. Ukuncamathela;

④ Ayinakuphiliswa kwindawo evalwe ngokupheleleyo (i-silica gel idinga ukunyangwa ngumswakama emoyeni);

⑤ Umphezulu we-substrate awucocekanga okanye womelele.
