Kwiminyaka yakutshanje, kubekho imozulu embi kakhulu kwihlabathi liphela, nto leyo eye yavavanya ishishini lethu lezitywina, ingakumbi kwiifektri zaseTshayina ezifana nathi ezithumela kwamanye amazwe kuzo zonke iindawo zehlabathi.
Kwiiveki ezimbalwa ezidlulileyo eTshayina, imvula eqhubekayo kunye namaqondo obushushu aphezulu akushiyanga ndawo yokuphumla. Ngoko ke ungazifaka njani ngokuchanekileyo izitywini kwindawo enobushushu obuphezulu kunye nomswakama ophezulu?
1 Ukupakishwa nokugcinwa kwezinto zokutywina
Ekubeni izinto zokutywina ziyimveliso yeekhemikhali, indlela yokutywina kukusabela nokuqina xa kufikwa kumswakama. Xa zifakwe emanzini, ukupakisha kwangaphandle kwezinto zokutywina kunokudlala indima encinci yokuthintela. Ke ngoko, ehlotyeni, izinto zokutywina kufuneka zigcinwe kwindawo elele phezulu, enomoya opholileyo kwaye epholileyo ukuthintela izinto zokutywina ukuba zingafakwa emvuleni okanye zifakwe emanzini abangelwa yimozulu embi kakhulu, eya kuchaphazela ubomi beshelufu yemveliso kwaye ibangele iingxaki zokutywina kwiphakheji yemveliso.
Izinto zokutywina ezifakwe emanzini kufuneka zisuswe kwindawo yokuntywila ngokukhawuleza kwaye zidluliselwe kwigumbi elomileyo nelinomoya. Ibhokisi yokupakisha yangaphandle kufuneka isuswe, umphezulu kufuneka ucinywe wome uze ubekwe ngaphakathi ukuze usetyenziswe ngokukhawuleza.
2 Indlela echanekileyo yokufaka isitywina
Ngaphambi kokufaka isicelo, nceda uqaphele oku kulandelayo:
Imfuneko yobushushu obungqongileyo kwiSiway brandisitywini se-siliconeiimveliso ziyi: 4℃～40℃, indawo ecocekileyo enomswakama oqhelekileyo we-40%～80%.
Kwiindawo ezingezizo iimfuneko zobushushu kunye nokufuma ezingasentla, abasebenzisi abacetyiswa ukuba bafake isitywini.
Ehlotyeni, ubushushu bangaphandle buphezulu, ngakumbi kwiindonga zekhethini ze-aluminium, apho ubushushu buphezulu nangakumbi. Ukuba ubushushu obuphakathi kunye nokufuma azikho ngaphakathi koluhlu olucetyiswayo, kucetyiswa ukuba kwenziwe uvavanyo lwesicelo se-sealant kwindawo encinci, kwaye kwenziwe uvavanyo lokuncamathela okuqhekekayo ukuqinisekisa ukuba ukunamathela kulungile kwaye akukho ziganeko zimbi ngaphambi kokuba uyisebenzise kwindawo enkulu.
Ngexesha lesicelo, nceda ulandele la manyathelo angezantsi:
Ulandelelwano lolwakhiwo lwesitywini solwakhiwo (isitywini solwakhiwo kwiindonga zekhethini, isitywini solwakhiwo esineengqimba ezimbini kwimingxuma, njl.njl.):
1） Coca isiseko
Ubushushu buphezulu ehlotyeni, kwaye isinyibilikisi sokucoca kulula ukusiguqula sibe buthathaka. Nika ingqalelo kwimpembelelo yesiphumo sokucoca.
2） Faka iprimer (ukuba kuyimfuneko)
Ehlotyeni, ubushushu kunye nokufuma kuphezulu, kwaye i-primer kulula ukuyinyibilikisa kwaye ilahlekelwe ngumsebenzi wayo emoyeni. Nika ingqalelo ekufakeni iglu ngokukhawuleza emva kokusebenzisa i-primer. Kwangaxeshanye, kufuneka kuqatshelwe ukuba xa uthatha i-primer, inani lamaxesha kunye nexesha i-primer edibana ngalo nomoya kufuneka lincitshiswe kangangoko. Kungcono ukusebenzisa ibhotile encinci yokutshintsha ukuze upakishe.
3） Inaliti yesitywina
Emva kokufakwa kweglue, isitywini esimelana nemozulu asinakusetyenziswa ngoko nangoko ngaphandle, kungenjalo isantya sokunyanga sesitywini solwakhiwo siya kuncipha kakhulu.
4） Ukucheba
Emva kokuba kugqityiwe ukufakwa kweglue, kufuneka kucuthwe ngoko nangoko, nto leyo evumela ukuba i-sealant kunye necala le-interface ziqhagamshelane.
5） Ukurekhoda nokumakisha
Emva kokuba le nkqubo ingasentla igqityiwe, bhala phantsi uze uphawule ngexesha.
6） Ukugcinwa
Iyunithi kufuneka icocwe ixesha elaneleyo phantsi kweemeko ezingashukumiyo nezingenaxinzelelo ukuqinisekisa ukuba isitywini solwakhiwo sinamathele ngokwaneleyo.
Ulandelelwano lokwakhiwa kwesitywini esimelana nemozulu kunye nesitywini somnyango nefestile:
1） Ukulungiswa kwejoyinti yesitywina
Intonga yefoam edibana ne-sealant kufuneka igcinwe injalo. Ubushushu buphezulu ehlotyeni, kwaye ukuba intonga yefoam yonakele, kulula ukubangela amadyungudyungu; kwangaxeshanye, kufuneka kuqwalaselwe ukuhambelana kwe-substrate kunye ne-sealant.
2） Coca isiseko
I-glue joint kufuneka icocwe endaweni yayo ukuze kususwe uthuli, ioyile, njl.
3） Faka iprimer (ukuba kuyimfuneko)
Okokuqala, qiniseka ukuba umphezulu we-substrate yeglue joint womile ngokupheleleyo. Ehlotyeni, ubushushu kunye nokufuma kuphezulu, kwaye i-primer ifakwa lula emoyeni kwaye ilahlekelwa ngumsebenzi wayo. Kufuneka kuqatshelwe ukuba i-glue kufuneka ifakwe ngokukhawuleza emva kokuba i-primer ifakiwe. Kwangaxeshanye, kufuneka kuqatshelwe ukuba xa uthatha i-primer, inani kunye nexesha lokudibana nomoya kufuneka lincitshiswe kangangoko. Kungcono ukusebenzisa ibhotile encinci yokutshintsha ukuze upakishe.
4） Inaliti yesitywina
Kukho iindudumo ezininzi ehlotyeni. Qaphela ukuba emva kwemvula, i-glue joint kufuneka yome ngokupheleleyo ngaphambi kokuba ufake i-glue.
5） Ukugqiba
Ubushushu ehlotyeni buphezulu, kwaye ixesha lokugqiba lifutshane kunakwezinye iisizini. Emva kokuba ukufakwa kweglu kugqityiwe, ukugqitywa kufuneka kwenziwe ngoko nangoko.
6） Ukugcinwa
Kwinqanaba lokuqala lokugcinwa, akufuneki kubekho ukufuduka okukhulu.
Iingxaki eziqhelekileyo, Indlela yokujongana nazo:
1. Ixesha elifutshane lokuphumla kwe-sealant yolwakhiwo enamacandelo amabini
Isigwebo: Ixesha lokuphumla lifutshane kunexesha lokuphumla eliphantsi elicetyiswe ngumenzi.
Isizathu: Ubushushu obuphezulu kunye nokufuma ehlotyeni kuyalinciphisa ixesha lokuphumla.
Isisombululo: Lungisa umlinganiselo wezinto u-A no-B ngaphakathi koluhlu olucetyiswe ngumenzi.
2. Ukungasebenzi kakuhle kweprimer yesitywina yesakhiwo
Isizathu: Ubushushu obuphezulu kunye nokufuma ehlotyeni, ukusetyenziswa gwenxa kweprimer kunokuphulukana nomsebenzi wayo ngokulula. Iprimer engasebenzi kakuhle iya kukhokelela ekubotshelelweni kakubi kwe-structural sealant.
Isisombululo: Kungcono ukusebenzisa iibhotile ezincinci njenge-primer. Akukhuthazwa ukusebenzisa i-primer engasetyenziswanga kwi-sub-bottle ubusuku bonke. Kwangaxeshanye, kufuneka kuqatshelwe ukuba xa uthatha i-primer, inani kunye nexesha lokudibana phakathi kwe-primer nomoya kufuneka kuncitshiswe kangangoko kunokwenzeka. Kwaye jonga imeko ye-primer kwi-sub-bottle ngexesha. Ukuba imbonakalo itshintshile ngenxa yexesha elide lokugcina, i-primer kwi-sub-bottle akufuneki isetyenziswe.
3. Isitywini esitshintsha imozulu/isitywini socango kunye nefestile
Indlela yokugweba: Kukho amaqhuma akufutshane kumphezulu we-silicone sealant. Xa umcu ocociweyo unqunyulwa, ngaphakathi kuba mnyama.
Isizathu ①: Umphezulu wentonga yefoam uyabhobozwa ngexesha lenkqubo yokuzalisa, kwaye umoya ukhutshwa emngxunyeni emva kokuba ucinezelwe;
Isisombululo: Icala lentonga yefoam edibene ne-sealant lihlala linjalo. Ukuba kunzima ukuyizalisa, ungayinqumla inxalenye engasemva kwentonga yefoam.
Isizathu ②: Ezinye ii-substrates zisabela kunye ne-sealants;
Isisombululo: Nika ingqalelo ekuhambelaneni kweentlobo ezahlukeneyo zezitywina kunye nezinto ezisetyenziswa phantsi kwazo, kwaye kufuneka uvavanyo lokuhambelana.
Isizathu ③: Ukudumba okubangelwa kukwanda kobushushu begesi kwindawo etywiniweyo yeglue;
Isizathu esithile sisenokuba kuyo yonke i-glue joint evaliweyo, umoya ovalekileyo kwi-glue joint emva kokufakwa uyanda ngomthamo xa ubushushu buphezulu (ngokubanzi bungaphezulu kwe-15°C), nto leyo ebangela ukudumba kumphezulu we-sealant engekaqini.
Isisombululo: Kuphephe ukuvala ngokupheleleyo kangangoko kunokwenzeka. Ukuba kuyimfuneko, shiya icandelo elincinci lemingxuma yomoya uze uyizalise emva kokuba i-sealant iqine.
Isizathu ④: Ujongano okanye izinto ezincedisayo zimanzi;
Isisombululo: Musa ukwakha ngeentsuku zemvula, linda de imozulu icoceke kwaye i-glue joint yome.
Isizathu ⑤: Ulwakhiwo phantsi kweemeko zobushushu obuphezulu ngaphandle;
Isisombululo: Misa ulwakhiwo phantsi kweemeko zobushushu obuphezulu ngaphandle uze ulinde de ubushushu behle ngaphambi kokuba wakhe.
4. Ixesha elifutshane lokulungisa isitywini/isitywini somnyango kunye nefestile esingamelani nemozulu
Isizathu: Ubushushu kunye nokufuma kuphezulu ehlotyeni, kwaye ixesha lokutsala lifutshane.
Isisombululo: Ukulungiswa ngexesha emva kokufakwa kwenaliti.
Lumka xa usakha kwaye ulandele imiyalelo ukuqinisekisa umgangatho.
Ubushushu obuphezulu kunye nemvula enkulu zizinto ezinzima, kwaye kukho amaqhinga okwakha isitywini.
Sombulula iingxaki ngexesha elifanelekileyo ukuqinisekisa ukhuseleko lweprojekthi.
I-SIWAY ihamba nawe ehlotyeni elishushu kwaye inika amandla ubuhle kunye!
