Ukusukela ngoDisemba, kubekho ukwehla kwamaqondo obushushu kwihlabathi liphela:
Ummandla waseNordic: Ummandla waseNordic uqalise ukubanda okukhulu kunye neemvula ezinkulu kwiveki yokuqala ka-2024, kunye namaqondo obushushu aphantsi kakhulu angama--43.6℃ kunye nama--42.5℃ eSweden naseFinland ngokulandelelana. Emva koko, impembelelo yokuhla okukhulu kwamaqondo obushushu yasasazeka ngakumbi kwiNtshona Yurophu nakwiMbindi Yurophu, kwaye i-United Kingdom kunye neJamani zikhuphe izilumkiso zemozulu etyheli ngenxa yokubanda.
IYurophu eseMbindini neseMazantsi: Iqondo lobushushu kumbindi nakumazantsi eYurophu nakwezinye iindawo lehle nge-10 ukuya kwi-15℃, kwaye iqondo lobushushu kwiindawo eziphakamileyo zeentaba lehle nge-15 ukuya kwi-20℃. Iqondo lobushushu kwezinye iindawo ezikumntla Jamani, kumazantsi ePoland, empuma yeCzech Republic, kumantla eSlovakia, nakwimbindi yeRomania lehle kakhulu.
Iindawo zaseTshayina: Ubushushu kwiindawo ezininzi zaseMantla-mpuma yeTshayina, kumzantsi-mpuma weMpuma yeTshayina, embindini nakumzantsi-mpuma weTshayina, nakumzantsi-mpuma weTshayina uphantsi kunexesha elifanayo leminyaka edlulileyo.
Emantla Melika: Ubushushu kumantla mpuma eMelika nakwiCanada ephakathi nakumantla buye behla nge-4 ukuya kwi-8℃, kwaye badlula kwi-12℃ kwezinye iindawo.
Ezinye iindawo zaseAsia: Ubushushu embindini weRashiya behle ngo-6 ukuya kwi-10℃, kwaye badlula kwi-12℃ kwezinye iindawo.
Ukwehla ngequbuliso kobushushu kunye nomoya obandayo ovuthuzayo ziyadibana. Njengesixhobo esibalulekileyo esincedisayo esisetyenziswa kakhulu ekubopheni nasekuvaleleni kwiindawo zokwakha iindonga zamakhethini, iingcango kunye neefestile, imihombiso yangaphakathi, njl.njl.,izinto zokutywinabasebenza ngokuzimisela kuzo zonke iinkcukacha. Kwanasebusika, abayeki ukusebenza ngokuzimisela ukuze bahlukanise ingqele ngaphandle "kwesithintelo".
Ubushushu obuphantsi kakhulu ebusika buphantsi kakhulu, kwaye ezi ngxaki zilandelayo zinokwenzeka:
(1) Phantsi kweemeko zobushushu obuphantsi kunye nokufuma okuphantsi, isantya sokuphiliswa kunye nesantya sokubopha se-silicone structural sealants sihamba kancinci kunesiqhelo, nto leyo eya kubangela ukuba ixesha lokulungisa libe lide kwaye lichaphazele ulwakhiwo.
(2) Xa ubushushu buphantsi kakhulu, ukufuma kwe-silicone structural sealants kunye nomphezulu we-substrate kuyancitshiswa, kwaye kusenokubakho inkungu okanye iqabaka engabonakaliyo kumphezulu we-substrate, nto leyo echaphazela ukunamathela kwe-silicone structural sealants kwi-substrate.
Iindlela zokulwa nokwakhiwa kwebusika
Ngoko ke yintoni esifanele siyiqwalasele ukuze siphephe ezi ngxaki zingasentla?
Okwangoku, kukho iintlobo ezimbini ze-silicone structural sealants zokwakha ezisetyenziswa ekwakheni udonga lwekhethini: enye yi-single-component silicone structural sealant, kwaye enye yi-two-component silicone structural sealant. Indlela yokulungisa kunye nezinto ezichaphazela ukuqina kwezi ntlobo zimbini ze-silicone structural sealants ziboniswe kwitheyibhile engasezantsi.
| Icandelo elinye | Izinto ezimbini |
| Isabela namanzi emoyeni ize iqine kancinci kancinci ukusuka phezulu ukuya ngaphakathi. (Okukhona umthungo weglue unzulu, kokukhona kuthatha ixesha elide ukuphola ngokupheleleyo) | Inyangwa yindlela esebenza ngayo icandelo A (eliqulathe amanzi amancinci), icandelo B kunye nokufuma emoyeni, umphezulu kunye nangaphakathi ziyanyangwa ngaxeshanye, isantya sokunyangwa komphezulu sikhawuleza kunesantya sokunyangwa kwangaphakathi, sichaphazeleka bubungakanani bomthungo weglue kunye nemeko yokutywina) |
| Isantya sokuphilisa sicotha kuneso sezinto ezimbini, isantya asinakulungiswa, kwaye sichaphazeleka lula bubushushu kunye nokufuma okungqongileyo. Ngokubanzi, okukhona ubushushu buphantsi, kokukhona isantya sokuphendula sicotha; okukhona ukufuma kuphantsi, kokukhona isantya sokuphendula sicotha. | Isantya sokufunxa sikhawuleza, kwaye isantya sinokulungiswa ngobungakanani becandelo B. Alichaphazeleki kangako bumswakama obungqongileyo kwaye lichaphazeleka ngakumbi bubushushu. Ngokubanzi, okukhona ubushushu buphantsi, kokukhona ukufunxa kucotha. |
NgokweCandelo 9.1 le-JGJ 102-2013 "Iinkcukacha zobugcisa zobunjineli bodonga lwekhethini yeglasi", ukufakwa kwe-silicone structural sealant kufuneka kwenziwe phantsi kweemeko zobushushu kunye nokufuma ezihambelana nemigangatho yemveliso. Umzekelo, iimfuno zokusingqongileyo zokusetyenziswa kweemveliso ze-siway silicone structural sealant zezi: indawo ecocekileyo enobushushu obuyi-10℃ ukuya kwi-40℃ kunye nokufuma okulinganiselweyo kwe-40% ukuya kwi-80%, kwaye kuthintele ukwakhiwa kwimozulu enemvula nekhephu.
Kwixesha lokwakha lasebusika, ukuqinisekisa ukuba ubushushu bokwakha abukho ngaphantsi kwe-10℃, kufuneka kuthathwe amanyathelo okufudumeza afanelekileyo. Ukuba umsebenzisi ufuna ukwakha kwindawo engaphantsi kancinci kwe-10℃ ngenxa yeemeko ezikhethekileyo, kucetyiswa ukuba kuqala enze uvavanyo lweglue oluncinci kunye novavanyo lokuncamathela oluxobukayo ukuqinisekisa ukuba iziphumo zokuphilisa kunye nokunamathela kwe-silicone sealant zilungile, kwaye wandise ixesha lokulungisa ngokufanelekileyo ngokwemeko. Ukuba kuyimfuneko, cinga ngokusebenzisa i-xylene ukucoca kunye nokusebenzisa i-primer ukukhuthaza isantya sokunamathela kunye nokunciphisa umngcipheko wokunamathela okubi ngenxa yobushushu obuphantsi.
Amanyathelo okuchasa ukucotha konyango
① Thatha amanyathelo okufudumeza afanelekileyo;
② Isitywini esineenxalenye ezimbini kufuneka siqale sivavanywe ukuba asiphukanga na ukuze kuchongwe umlinganiselo ofanelekileyo wokuxuba;
③ I-sealant enecandelo elinye kufuneka ivavanywe ukuze kubonwe ukuba inganyangwa na kule ndawo;
④ Kucetyiswa ukuba kwandiswe ixesha lokunyibilikisa emva kokuncamathisela ukuqinisekisa ukuba isitywini sinexesha elaneleyo lokunyibilikisa nokunyibilikisa.
Amanyathelo okuchasa ukungaphumeleli kokubopha
① Uvavanyo lokuncamathela kufuneka lwenziwe kwangethuba ngaphambi kokuba kwakhiwe, kwaye ulwakhiwo kufuneka lwenziwe ngokungqongqo ngokwendlela ecetyiswe luvavanyo lokuncamathela.
② Ukuba kuyimfuneko, cinga ngokusebenzisa i-xylene ekucoceni nasekufakeni i-primer ukukhuthaza isantya sokubopha kunye nokunciphisa umngcipheko wokubopha okubi okubangelwa kubushushu obuphantsi.
③ Emva kokuba i-silicone structural sealant ifakiwe, inkqubo yokulungisa kufuneka yenziwe kwindawo ecocekileyo nengena umoya. Xa ubushushu kunye nokufuma kwendawo yokulungisa kuphantsi, ixesha lokulungisa kufuneka landiswe ngokufanelekileyo. Phakathi kwazo, imeko yokulungisa ye-single-component structural sealant inobudlelwane obubalulekileyo nexesha lokulungisa. Phantsi kwendawo efanayo, kokukhona ixesha lokulungisa lide, kokukhona inqanaba lokulungisa liphezulu.
Ukuba kuyimfuneko, amanyathelo anokuthathwa ukonyusa ubushushu kunye nokufuma kwemozulu. Uvavanyo lokugqibela lokucofa irabha kufuneka lusetyenziswe njengesiseko sokumisela ngokupheleleyo ixesha lokugcinwa kweyunithi egqityiweyo. Kuphela emva kokuba uvavanyo lokucofa irabha olugqityiweyo lufanelekile (jonga umfanekiso ongezantsi) apho lunokuthi lufakwe kwaye luthuthwe.
Njengenye yezixhobo zokwakha, i-sealant idlala indima ebalulekileyo kwaye ichaphazela ngokuthe ngqo umsebenzi, ubomi benkonzo kunye nexabiso lesakhiwo, ngoko ke inkqubo yokwakha kufuneka ilawulwe ngokungqongqo xa kusetyenziswa iglu. Xa kusakhiwa ebusika nakwiimeko zobushushu obuphantsi, ukubopha kwangempela kwe-sealant kufuneka kuqinisekiswe ngokuhambelana nemigangatho efanelekileyo ukuqinisekisa ukuba i-sealant inokuqinisekisa ngokufanelekileyo isiphumo sokutywina kwesakhiwo. Yasekwa ngo-1984, iShanghai siway, inamathela entliziyweni yobugcisa, izibophelele ekuboneleleni ngezisombululo zeglue yenkqubo yokutywina kwiindonga zekhethini zesakhiwo sehlabathi, iglasi engenanto, iinkqubo zomnyango neefestile, iglue yoluntu, izakhiwo ezenziwe ngaphambili kunye namacandelo emizi-mveliso afana namandla, ezothutho, izibane, izixhobo zombane, unxibelelwano lwe-5G kunye ne-elektroniki yabathengi, amakhaya akrelekrele, izixhobo zamandla, njl.njl., ikhokela uphuhliso olukhuselekileyo, olusempilweni, oluluhlaza noluzinzileyo kushishino, kwaye yenza ukhetho lwakho olufanelekileyo kwiinkcukacha ezincinci.
Kweli xesha libandayo, masinyamekele yonke into ngentliziyo efudumeleyo ukuqinisekisa umgangatho wolwakhiwo kunye nefuthe lezinto zokutywina ze-silicone structural.
