Ukusukela ngoDisemba, kuye kwakho ukwehla kobushushu kwihlabathi jikelele:
Ummandla weNordic: Ummandla weNordic ungenise ingqele eqhaqhazelisa amazinyo kunye nekhephu kwiveki yokuqala ka-2024, ngamaqondo obushushu asezantsi kakhulu -43.6℃ kunye -42.5℃ eSweden naseFinland ngokulandelelanayo. Emva koko, iimpembelelo zokuhla kweqondo lobushushu elikhulu zanwenwa ngakumbi kwiNtshona Yurophu nakuMbindi Yurophu, kwaye iUnited Kingdom neJamani zakhupha izilumkiso zemozulu etyheli malunga nomkhenkce.
Embindini naseMazantsi Yurophu: Iqondo lobushushu kumbindi nasemazantsi eYurophu nakwezinye iindawo lehle nge-10 ukuya kwi-15℃, kwaye iqondo lobushushu kwiindawo eziphakamileyo zeentaba lehla nge-15 ukuya kwi-20℃. Iqondo lobushushu kwimimandla ethile kumntla Jamani, emazantsi ePoland, empuma Czech Republic, kumantla eSlovakia nakumbindi Romania lehla ngokuphawulekayo.
Amacandelo aseTshayina: Iqondo lokushisa kwiindawo ezininzi zoMntla-mpuma weChina, umzantsi-mpuma we-East China, umbindi kunye nomzantsi we-South China, kunye nomzantsi-mpuma we-Southwest China uphantsi kunexesha elifanayo leminyaka edlulileyo.
KuMntla Melika: Iqondo lobushushu kumntla-mpuma we-United States kunye nombindi nomntla weKhanada lehle nge-4 ukuya kwi-8℃, laze lagqitha kwi-12℃ kwezinye iindawo.
Ezinye iindawo zaseAsia: Iqondo lobushushu kumbindi weRashiya lehle nge-6 ukuya kwi-10℃, laze lagqitha kwi-12℃ kwezinye iindawo.
Ukuhla ngesiquphe kobushushu kunye nomoya obandayo obhudlayo ziyadibana. Njengezinto ezincedisayo ezibalulekileyo ezisetyenziselwa ukudibanisa kunye nokutywinwa kwimimandla yokwakha iindonga zamakhethini, iingcango kunye neefestile, ukuhlobisa kwangaphakathi, njl.izitywinisebenzani ngenkuthalo kuzo zonke iinkalo. Nasebusika, abakhe bayeke ukusebenza ngenkuthalo ukwahlula ingqele ngaphandle “kwesithintelo”.
Iqondo lobushushu kwindawo yasebusika liphantsi kakhulu, kwaye ezi ngxaki zilandelayo zisenokwenzeka:
(1) Ngaphantsi kobushushu obuphantsi kunye neemeko zokufuma okuphantsi, isantya sokunyanga kunye nesantya se-bonding se-silicone sealants structural sealants sicotha kunesiqhelo, esiya kubangela ukuba ixesha lokulondoloza libe lide kwaye lichaphazele ukwakhiwa.

Imilinganiso yokwakha yasebusika
Ngoko yintoni esifanele sinikele ingqalelo kuyo ukuze siphephe ezi ngxaki zingasentla?
Okwangoku, kukho iintlobo ezimbini ze-silicone structural sealants ezisetyenziselwa ukwakhiwa kodonga lwamakhethini: enye i-silicone ye-structural sealant yecandelo elilodwa, kwaye enye inamacandelo amabini e-silicone structural sealant. Indlela yokuphilisa kunye nezinto ezichaphazela ukunyangwa kwezi ntlobo zimbini ze-silicone structural sealants ziboniswe kwitheyibhile engezantsi.
| Icandelo elinye | Amacandelo amabini |
| Isabela ngamanzi emoyeni kwaye iqina ngokuthe ngcembe ukusuka phezulu ukuya ngaphakathi. (Ngokuya unzulu umthungo weglu, kuthatha ixesha elide ukunyanga ngokupheleleyo) | Ukunyangwa ngokusabela kwecandelo A (eliqulathe umlinganiselo omncinci wamanzi), icandelo B kunye nokufuma emoyeni, umphezulu kunye nangaphakathi kuyaphiliswa ngaxeshanye, isantya sokunyanga umphezulu sikhawuleza kunesantya sokunyanga sangaphakathi, esichatshazelwa ubungakanani bomthungo weglue kunye nemeko yokutywinwa) |
| Isantya sokunyanga sihamba kancinci kuneso samacandelo amabini, isantya asikwazi ukulungelelaniswa, kwaye sichaphazeleka ngokulula kubushushu bendawo kunye nokufuma. Ngokubanzi, okukhona usezantsi iqondo lobushushu, kokukhona uyacotha isantya sokusabela; okukhona usezantsi ukufuma, kokukhona uyacotha isantya sokusabela. | Isantya sokunyanga sikhawuleza, kwaye isantya sinokuhlengahlengiswa ngobungakanani becandelo B. Ayichaphazeli kangako ukufuma okukhoyo kwaye ichaphazeleke kakhulu ngubushushu. Ngokuqhelekileyo, okukhona iqondo lobushushu lisezantsi, kokukhona licotha ukunyangwa. |
NgokweCandelo 9.1 le-JGJ 102-2013 "IiNgcaciso zobuGcisa boBunjineli boDonga lweGlasi yekhethini", Isitofu se-silicone se-structural sealant kufuneka siqhutywe phantsi kweemeko zobushushu kunye nokufuma okuhlangabezana nemilinganiselo yemveliso. Umzekelo, iimfuno zokusingqongileyo zokusetyenziswa kwe-siway silicone structural sealant yemveliso zezi: indawo ecocekileyo enobushushu obuyi-10 ℃ ukuya kuma-40℃ kunye nokufuma okunxulumene ne-40% ukuya kwi-80%, kwaye unqande ukwakhiwa kwimozulu yemvula nekhephu.
Kulwakhiwo lwasebusika, ukuqinisekisa ukuba ubushushu bokwakha abukho ngaphantsi kwe-10℃, amanyathelo afanelekileyo okufudumeza kufuneka athathwe. Ukuba umsebenzisi ufuna ukwakha kwindawo engaphantsi kancinane kune-10 ℃ ngenxa yeemeko ezikhethekileyo, kuyacetyiswa ukuba kuqala aqhube uvavanyo oluncinci lweglue kunye novavanyo lokuncamathelisa ukukrazula ukuqinisekisa ukuba ukunyanga kunye neziphumo zokubopha i-silicone sealant ilungile. kunye nokwandisa ngokufanelekileyo ixesha lokulondoloza ngokwemeko. Ukuba kuyimfuneko, cinga ukusebenzisa i-xylene ukucoca kunye nokusebenzisa i-primer ukukhuthaza isantya sokudibanisa kunye nokunciphisa umngcipheko wokubambisana kakubi ngenxa yokushisa okuphantsi.
Amanyathelo okuthintela ukunyanga okucothayo
① Thatha amanyathelo okufudumeza afanelekileyo;
② I-sealant yamacandelo amabini kufuneka iqale ivavanywe ukuphulwa ukumisela umlinganiselo ofanelekileyo wokuxuba;
③ Isitywina esinecandelo elinye kufuneka sivavanyelwe ixesha lokumisa umphezulu ukuze kubonwe ukuba sinokunyangeka na kwesi singqongileyo;
④ Kucetyiswa ukuba kwandiswe ixesha lokunyanga emva kwegluing ukuqinisekisa ukuba i-sealant inexesha elaneleyo lokunyanga kunye nokunyanga.
Amanyathelo okuthintela ukusilela kokudibanisa
① Uvavanyo lokunamathela kufuneka lwenziwe kwangaphambili ngaphambi kokwakhiwa, kwaye ulwakhiwo kufuneka luqhutywe ngokungqongqo ngokuhambelana nendlela ekhuthazwa luvavanyo lokubambelela.
② Ukuba kuyimfuneko, cinga ukusebenzisa i-xylene yokucoca kunye nokusebenzisa i-primer ukukhuthaza isantya sokudibanisa kunye nokunciphisa umngcipheko wokubambisana okungahambi kakuhle okubangelwa ukushisa okuphantsi.
③ Emva kokuba i-silicone ye-structural sealant ifakwe, inkqubo yokunyanga kufuneka iqhutywe kwindawo ecocekileyo kunye nomoya. Xa iqondo lobushushu kunye nokufuma kwendawo yokunyanga iphantsi, ixesha lokunyanga lifuna ukwandiswa ngokufanelekileyo. Phakathi kwazo, imeko yokuphilisa yecandelo elinye le-structural sealant inobudlelwane obubalulekileyo kunye nexesha lokuphilisa. Phantsi kwendawo enye, okukhona ixesha lokunyanga lide, kokukhona linyuka izinga lokunyanga.
Ukuba kuyimfuneko, amanyathelo anokuthathwa ukwandisa ubushushu be-ambient kunye nokufuma. Uvavanyo lokugqibela lokucofa irabha kufuneka lusetyenziswe njengesiseko sokumisela ngokupheleleyo ixesha lokugcinwa kweyunithi egqityiweyo. Kuphela emva kokuba uvavanyo lokucofa irabha olugqityiweyo lufanelekile (jonga umfanekiso ongezantsi) unokufakwa kwaye uhanjiswe.
Njengenye yezinto zokwakha, i-sealant idlala indima ebalulekileyo kwaye ichaphazela ngokuthe ngqo umsebenzi, ubomi benkonzo kunye nexabiso lesakhiwo, ngoko ke inkqubo yokwakha kufuneka ilawulwe ngokungqongqo xa usebenzisa iglue. Xa kwakhiwa ebusika kunye neemeko zokushisa eziphantsi, ukudibanisa kwangempela kwe-sealant kufuneka kuqinisekiswe ngokuhambelana nemigangatho efanelekileyo ukuqinisekisa ukuba i-sealant inokuqinisekisa ngokufanelekileyo umphumo wokutywinwa kwesakhiwo. Yasekwa ngo-1984, i-Shanghai siway, ibambelela kwintliziyo yobugcisa, izinikele ekuboneleleni izisombululo zeglue zeglue kwiindonga zesakhiwo sehlabathi jikelele, iglasi engenanto, iminyango kunye neenkqubo zefestile, iglue yoluntu, izakhiwo ezenziwe ngaphambili kunye neendawo zoshishino ezifana namandla, ukuthutha, ukukhanya, izixhobo zombane, unxibelelwano lwe-5G kunye nombane wabathengi, amakhaya ahlakaniphile, izixhobo zombane, njl., ekhokelela kushishino olukhuselekileyo, olunempilo, oluluhlaza kunye noluzinzileyo. uphuhliso, kunye nokwenza ukhetho lwakho olugqibeleleyo kwiinkcukacha ezifihlakeleyo.
Kweli xesha libandayo, masikhathalele zonke iinkcukacha ngentliziyo efudumeleyo ukuze siqinisekise umgangatho wokwakha kunye nesiphumo se-silicone structural sealants.
