Ukuba i-silicone sealant ineengxaki zomgangatho, iya kukhokelela ekuvuzeni kwamanzi, ukuvuza komoya kunye nezinye iingxaki, nto leyo eya kuchaphazela kakhulu ukuxinana komoya kunye nokuxinana kwamanzi kweengcango neefestile.
Imifantu kunye nokuvuza kwamanzi okubangelwa kukungasebenzi kakuhle kwesitywina somnyango kunye nefestile
Ngoko ke sikhetha njani isitywini esifanelekileyo seengcango neefestile?
1. Khetha ngokuchanekileyo iimveliso ezihlangabezana nemigangatho
Ngexesha lokukhetha isitywini, kufuneka kuqwalaselwe kungekuphela nje umgangatho esiwufikelelayo, kodwa nakwinqanaba laso lokufuduka elihambelanayo. Umthamo wokufuduka yeyona nto ibalulekileyo ekulinganiseni ukuthamba kwesisitywini. Okukhona umthamo wokufuduka uphezulu, kokukhona ukuthamba kwesisitywini sesilicone kungcono. Ukucubungula nokufakela iingcango neefestile kufuneka kukhethwe iimveliso ezinomthamo wokufuduka ongaphantsi kwe-12.5 ukuqinisekisa ukuxinana komoya ixesha elide kunye nokuxinana kwamanzi kweengcango neefestile.
Ngexesha lokufakelwa nokusetyenziswa kweengcango neefestile, isiphumo sokubopha phakathi kwe-sealant eqhelekileyo kunye nesamente yekhonkrithi sidla ngokuba sibi kakhulu kunakwiiprofayili ze-aluminium okanye iglasi yeengcango neefestile. Ke ngoko, kufanelekile ukukhetha iimveliso ezihambelana ne-JC/T 881 njenge-sealant yokufakela iingcango neefestile.
Iimveliso ezinezinga eliphezulu lokufuduka zinamandla angakumbi okumelana notshintsho lokufuduka kwamalungu. Kucetyiswa ukuba ukhethe iimveliso ezinezinga eliphezulu lokufuduka kangangoko kunokwenzeka.
2. Khethai-siliconeiimveliso zesitywina ngokuchanekileyo ngokwenjongo
Iifestile zesakhelo ezifihliweyo kunye neefeni ezivula isakhelo ezifihliweyo zifuna isitywini solwakhiwo ukuze zidlale indima yokubopha kwesakhiwo. Isitywini solwakhiwo sesilicone kufuneka sisetyenziswe, kwaye ububanzi kunye nobukhulu baso bokubopha kufuneka buhlangabezane neemfuno zoyilo.
Ngexesha lokufakelwa kweengcango neefestile, isitywini seejoyinti zamatye okanye iijoyinti ezinelitye kwelinye icala kufuneka sibe sisitywini esikhethekileyo selitye esihlangabezana nomgangatho we-GB/T 23261.
Isitywini esingatshiyo sifanelekile ngakumbi kwiingcango neefestile ezingatshiyo okanye iingcango zangaphandle kunye neefestile zezakhiwo ezifuna ukhuseleko lomlilo.
Kwiindawo ezifakelwa izicelo ezineemfuno ezikhethekileyo zokuthintela ukungunda, ezinje ngeekhitshi, iibhafu zokuhlambela kunye neendawo ezimnyama nezimanzi, ukuvalwa kweendawo zomnyango neefestile kufuneka kusetyenziswe isitywini esithintela ukungunda.
3. Musa ukukhetha i-silicone sealant egcwele ioyile!
Okwangoku, imakethi izele zizinto ezininzi ezitywina iingcango neefestile ezizaliswe yioyile, ezizaliswe yioyile eninzi yeeminerali kwaye zinokumelana nokuguga okunzima, nto leyo eya kukhokelela kwiingxaki ezininzi zomgangatho.
I-silicone sealant exutywe neoyile yeminerali ibizwa ngokuba yi-"oil filled silicone sealant" kweli shishini. Ioyile yeminerali yeye-saturated alkane petroleum distillation. Ngenxa yokuba isakhiwo sayo se-molecular sahlukile kakhulu kweso se-silicone, ukuhambelana kwayo nenkqubo ye-silicone sealant akulunganga, kwaye iya kuhamba kwaye ingene kwi-silicone sealant emva kwexesha elithile. Ke ngoko, "i-oil filled sealant" inokuqina okuhle ekuqaleni, kodwa emva kokusetyenziswa ixesha elithile, ioyile yeminerali ezalisweyo iyahamba kwaye ingene kwi-sealant, kwaye i-sealant iya kuncipha, iqine, iqhekeke, kwaye ide ibe nengxaki yokungabophi.
Uninzi lwee-silicone sealants ezingabizi kakhulu ezithengiswayo zizaliswe yioyile yeminerali, kwaye umxholo we-silicone basic polymer ungaphantsi kakhulu kune-50%, kwaye ezinye zingaphantsi nangaphantsi kwe-20%.
Ukuba isitywini sefestile yokuzalisa igesi sidibana neglasi yokugquma, ioyile yeminerali ezalisweyo iya kuhamba ize ingene kwiglasi yokugquma, nto leyo ebangela ukuba irabha yebutyl yokugquma yeglasi yokugquma kunye nokuhamba kweoyile kunyibilike.
Khetha iimveliso ze-sealant ezikumgangatho ophezulu. Nangona ixabiso le-sealant elithengwe kwinqanaba lokuqala liphezulu kancinci, ukusebenza kwayo kunokugcinwa ixesha elide ngaphandle kweengxaki zomgangatho. Khetha i-"oil filled sealant" engabizi kakhulu, nangona ixabiso liphantsi, iindleko zokuqala zotyalo-mali ziphantsi kancinci; Nangona kunjalo, emva kokuba kubekho iingxaki, iindleko zokugcina kamva, iindleko zemveliso, iindleko zomsebenzi, ilahleko zophawu, njl. ngexesha lokulungiswa kwakhona zinokuba zizihlandlo ezininzi okanye ziphindwe kaninzi kunexabiso le-sealant ngokwayo; Ayizange yonge imali kuphela, kodwa yongeze ingxaki enkulu kubasebenzisi.
