Uyazi? Ebusika, i-structural sealant nayo iya kuba njengomntwana, isenza umsindo omncinci, ngoko ke iza kubangela ziphi iingxaki?
1.Ukuqina kwe-sealant yesakhiwo
Izinto zokuvala ulwakhiwo ziya kuqina kancinci kancinci kwaye zibe bulwelo oluncinci njengoko ubushushu busiya buncipha. Kwinto yokuvala ulwakhiwo enamacandelo amabini, ukuqina kwento yokuvala ulwakhiwo kuya kwandisa uxinzelelo lomatshini weglue kwaye kunciphise ukuphuma kwento yokuvala ulwakhiwo. Kwinto yokuvala ulwakhiwo enecandelo elinye, into yokuvala ulwakhiwo iyanda, kwaye uxinzelelo lompu weglue ukuze ukhuphe into yokuvala ulwakhiwo luyanda, kwaye imisebenzi yesandla inokuvakala ngathi ithatha ixesha kwaye inzima.
Isisombululo: Ukuba akukho mpembelelo ekusebenzeni kakuhle kolwakhiwo, ukuqina kobushushu obuphantsi yinto eqhelekileyo, kwaye akukho manyathelo okuphucula afunekayo. Ukuba ichaphazela ukusebenza kakuhle kolwakhiwo, ungacinga ngokunyusa ubushushu bokusetyenziswa kwe-structural sealant okanye usebenzise amanye amanyathelo okufudumala ancedisayo, njengokugcina i-structural sealant kwigumbi lokufudumeza okanye elinomoya opholileyo kwangaphambili. Faka ubushushu kwindawo yokusebenzela yokuncamathisela ukuze unyuse ubushushu bendawo yokuncamathisela. Ukongeza, ungakhetha izixhobo ezifanelekileyo zokuncamathisela, njengemipu yeglue yesandla ene-high thrust, imipu yeglue ye-pneumatic, imipu yeglue yombane, njl.
2. Ukuqhekeka kwe-sealant yemozulu - ukubonakala okungalinganiyo
Ebusika, umahluko phakathi kobushushu phakathi kwemini nobusuku udla ngokuba mkhulu. Xa isetyenziswa eludongeni lwekhethini lephaneli ye-aluminiyam, i-sealant engamelani nemozulu idla ngokudumba. Isizathu esiphambili kukuba isantya sokuphiliswa kwe-sealant engamelani nemozulu siyacotha kwindawo enobushushu obuphantsi, kwaye ixesha elifunekayo ukuze umphezulu uphiliswe kubunzulu obaneleyo liya kuba lide. Kumphezulu we-sealant engamelani nemozulu Xa ubunzulu beglu bungakhange buphiliswe ngokwaneleyo, ukuba ububanzi bomthungo weglu buhluka kakhulu (oku kudla ngokubangelwa kukwanda kobushushu kunye nokucutheka kwephaneli), umphezulu womthungo weglu uya kuchaphazeleka kwaye kuya kuvela ukungalingani. Emva kokuba umthungo weglu onomphezulu ongalinganiyo ekugqibeleni uphiliswe, ingaphakathi lawo liqinile, alinamngxuma, elingayi kuchaphazela ukusebenza kokutywinwa kwexesha elide kwe-sealant engamelani nemozulu, kodwa lichaphazela kuphela ukuthamba kwembonakalo yomthungo weglu.
Emva kobusika, indawo enkulu iyaphola, ubushushu buphantsi, kwaye umahluko phakathi kobushushu kusasa nangokuhlwa mkhulu. Ngenxa yokwanda okukhulu kwezinto, udonga lwekhethini lephaneli ye-aluminiyam luyatshintshatshintsha kakhulu ngenxa yobushushu. Phantsi kweemeko ezingasentla zokwakhiwa kwe-sealant yesakhiwo, kukho ithuba elithile lokuba iindawo ezinamathelayo zodonga lwekhethini lephaneli ye-aluminiyam ziya kuvuvukala.
Isisombululo:
1. Khetha iglu enesantya esikhawulezayo sokucola, enokunciphisa ingxaki yokudumba kwe-sealant engamelani nemozulu.
2.Ukuba ukuguquguquka kwe-glue joint kukhulu kakhulu ngenxa yokufuma okuphantsi okanye umahluko wobushushu, ubungakanani be-glue joint, njl.njl., kucetyiswa ukuba ukhethe enye okanye ezingaphezulu kwezi ndlela zilandelayo zokwakha.
a).Thatha amanyathelo afanelekileyo okugquma, njengokukhusela i-scaffolding ngeenethi ezingangeni uthuli, ukuze iiphaneli zingavezwa ngqo elangeni, ukunciphisa ubushushu beephaneli, kunye nokunciphisa ukuguquka kwamalungu okubangelwa kukwahluka kobushushu.
b). Zama ukuncamathisela iglu malunga nemini emaqanda, kwaye uphephe ukuncamathisela kusasa nangokuhlwa.
c).Sebenzisa indlela yokufaka iglu yesibini (oko kukuthi, ukuba kukho umthungo weglue ogobileyo kwiglue yokuqala, inokunyangeka iintsuku ezi-2 ukuya kwezi-3, kwaye emva kokuba ithambile, kongezwa umaleko weglue phezu komphezulu).
