Iglu yodonga lwekhethini yinto efunekayo kwiiprojekthi zokwakha, kwaye isetyenziswa kwisakhiwo sodonga lwekhethini lwesakhiwo sonke, esinokubizwa ngokuba "yimfanelo engabonakaliyo". Iglu yodonga lwekhethini inamandla aphezulu, iyamelana nokukrazuka, iyamelana nempembelelo, kulula ukuyila, kwaye isetyenziswa kakhulu ekwakheni nasekufakeni, ekuhombiseni, ekutywineni, ekubopheni ulwakhiwo nakwezinye iindawo. Icala lophuhliso lwezakhiwo zanamhlanje liza kuba kuyilo (umgangatho, ukwenziwa koomatshini bokwakha, ukwenziwa kwangaphambili kwezinto kunye nobunzima obulula, amandla aphezulu kunye nezixhobo zokwakha ezisebenza ngeendlela ezininzi). Kwaye iglu yodonga lwekhethini isetyenziswa kakhulu, iya kukhawulezisa inkqubo yale mine, kwaye ekuphuculeni isantya sokwakha, ihombise isakhiwo, iphucule umgangatho wokwakha, yonge ixesha namandla, inciphise ungcoliseko kunye nezinye izinto ezininzi ezibalulekileyo, ngoko ke iglu yodonga lwekhethini ibe yenye yezinto ezibalulekileyo zokwakha iikhemikhali. Ziziphi iingxaki eziqhelekileyo ezifunyanwa ekwakhiweni kweglu yobunjineli bodonga lwekhethini edlala indima ephambili? Sijongana njani nazo?
1.iglu yolwakhiwo enamandla aphezulu kwimeko apho kufuneka ubungqina bengcali bube khona?
Kudonga lweglasi olune-structural silicone sealant super specification design, iiprojekthi zodonga lwe-curtain kufuneka zisebenzise i-junbond brand ultra-high performance structural silicone sealant ukuphucula ixabiso le-f1 (ixabiso loyilo lwe-structural silicone sealant strength strength xa kukho umoya okanye inyikima), ixabiso le-f2 (ixabiso loyilo lwe-structural silicone sealant strength xa kukho umthwalo osisigxina), ixabiso le-δ (umthamo we-structural silicone sealant displacement bearing, ukusombulula inkqubo yoyilo. Ububanzi okanye ubukhulu boyilo lwe-structural silicone sealant obudibene nabo budlula ixabiso le-specification. Ukuba kunokwenzeka kolu lwakhiwo lwe-super specification, imfuneko yesikhokelo kwiprojekthi ikwiphondo lezindlu kunye nesebe lokwakha izixeko kunye nelasemaphandleni ukuze lifake isicelo, isebe lezindlu kunye nelasemaphandleni ukuze lilungiselele ixesha lokuqesha iqela leengcali, ukuze kuqinisekiswe iingcali.
2. Iza kuba yintoni impembelelo yokufunxa ixesha elide i-adhesive yolwakhiwo kunye ne-adhesive engangeni manzi? Iza kuba nefuthe elingakanani ekusebenzeni kokufunxa?
Izincamathelisi zesakhiwo kunye nemozulu zii-silicone sealants (ngenxa yesakhiwo se-molecular se-silicone sealants ngokwazo, amanzi ahlala ixesha elide emanzi, ezinye iibhondi zeekhemikhali ziya kufakelwa i-hydrolyzed kwaye zaphuke, ukusilela kokubopha. Kwi-GB16776 standard "yokwakha i-silicone structural sealant", i-silicone structural sealant ephilisiweyo kufuneka yenze uvavanyo lokubopha, uvavanyo lokucwilisa iintsuku ezili-14, i-bonding iselungile. Kwi-American standard ASTM 1184, i-structural sealant kufuneka ivavanywe ngamanzi i-UV iiyure ezingama-5000, i-junbond brand structural adhesive inokuphumelela uvavanyo ngaphandle kweengxaki. Nangona kunjalo, kuxhomekeke kuyilo lweefomyula ezahlukeneyo ze-silicone adhesives, mhlawumbi zifakwe emanzini iinyanga eziliqela ukuya kwiminyaka eliqela, ziya kuchaphazela ukusebenza. Kwiimeko zobunjineli bokwenyani, i-silicone sealant ayifanelekanga ukucwiliswa ixesha elide kwindawo engqongileyo, njenge-aquariums kunye nezinye iindawo zokubopha ezingaphantsi kwamanzi.
3. Ngaba i-adhesive yesakhiwo seglasi yeyunithi ingadlala indima yokutywina engangeni manzi?
I-adhesive yolwakhiwo lweglasi yeyunithi inokudlala indima ethile yokuvala amanzi. Nangona kunjalo, uyilo lodonga lwekhethini, alunakufikelela kwiimfuno zokuvala amanzi, okanye kufuneka luxhomekeke kwi-adhesive yangaphandle yemozulu ukuhlangabezana neemfuno zokuvala, kwaye i-adhesive yolwakhiwo ukuntywiliselwa emanzini ixesha elide nayo iya kuchaphazela ukubopha kwayo, inciphise ukhuseleko lodonga lwekhethini. Ukuba i-adhesive yolwakhiwo isetyenziswa njenge-adhesive yemozulu, amandla ayo okufuduka anokungakwazi ukuhlangabezana neemfuno zokususwa komthungo wodonga lwekhethini, ukuqina kokuvala akulunganga njenge-adhesive yemozulu ekhethekileyo.
