Kwiminyaka yakutshanje, bekukho imozulu embi ngakumbi nangakumbi kwihlabathi jikelele, ekwavavanye umzi-mveliso wethu wokutywina, ngakumbi kwiifektri zaseTshayina ezifana nathi ezithumela ngaphandle kuzo zonke iindawo zehlabathi.
Kwiiveki ezimbalwa ezidlulileyo e-China, imvula eqhubekayo kunye namaqondo obushushu aphezulu ashiye indawo yokuphefumla. Ngoko ke ungafaka njani ngokuchanekileyo ama-sealants kwindawo yokushisa ephezulu kunye nokufuma okuphezulu?
1 Ukupakishwa kunye nokugcinwa kwezitywini
Kuba izinto zokutywina ziyimveliso yeekhemikhali, indlela yokunyanga kukusabela kwaye yomelele xa idibana nokufuma. Xa ifakwe emanzini, ukupakishwa kwangaphandle kwee-sealants kunokudlala kuphela indima yomqobo. Ke ngoko, ehlotyeni, ii-sealants kufuneka zigcinwe kwindawo ephezulu, enomoya kunye nepholileyo ukuthintela izitywini ukuba zifakwe emvuleni okanye zifakwe emanzini okubangelwa yimozulu embi kakhulu, eya kuchaphazela ubomi beshelufu yemveliso kunye nonobangela. ukunyanga iingxaki kwipakethe yemveliso.
Ii-sealants ezifakwe emanzini kufuneka zisuswe ngokukhawuleza kwindawo yokumanzisa kwaye zidluliselwe kwigumbi elomileyo nelingena umoya. Ibhokisi yokupakisha yangaphandle kufuneka isuswe, umphezulu kufuneka ucinywe wome kwaye ufakwe ngaphakathi ukuze usetyenziswe ngokukhawuleza.
2 Indlela echanekileyo yokufakwa kwe-sealant
Ngaphambi kokufaka isicelo, nceda uqaphele oku kulandelayo:
Imfuno yobushushu be-ambient ye-brand ye-Siwayi-silicone sealantiimveliso zezi: 4℃～40℃, indawo ecocekileyo enokufuma okungama-40%～80%.
Kwiimeko ezingaphandle kwezi mfuno zobushushu kunye nokufuma okungentla, abasebenzisi abakhuthazwa ukuba bafake isitywini.
Ehlotyeni, iqondo lokushisa langaphandle liphezulu, ngakumbi kwiindonga ze-aluminiyam zamakhethini, apho iqondo lokushisa liphezulu ngakumbi. Ukuba ubushushu be-ambient kunye nokufuma abukho phakathi koluhlu olucetyiswayo, kuyacetyiswa ukuba kuqhutywe indawo encinci yovavanyo lwesicelo se-sealant kwindawo, kwaye wenze uvavanyo lokuncamathisela ukuze uqinisekise ukuba ukunamathela kulungile kwaye akukho ziganeko zimbi ngaphambili. ukuyisebenzisa kwindawo enkulu.
Ngexesha lokufaka isicelo, nceda ulandele la manyathelo angezantsi:
Ulandelelwano lolwakhiwo lwesitywina solwakhiwo (isixhobo sokutywina sokwakheka kweendonga zekhethini, isitywini sesakhiwo esinemiqolo emibini, njl.njl.):
1) Coca i-substrate
Iqondo lokushisa liphezulu ehlotyeni, kwaye i-solvent yokucoca kulula ukuguquguquka. Nika ingqalelo kwimpembelelo kwisiphumo sokucoca.
2) Faka iprimer (ukuba kuyimfuneko)
Ehlotyeni, iqondo lokushisa kunye nokufuma kuphezulu, kwaye i-primer ilula i-hydrolyze kwaye ilahlekelwe ngumsebenzi wayo emoyeni. Nika ingqalelo ekufakeni iglue ngokukhawuleza emva kokusebenzisa i-primer. Ngexesha elifanayo, kufuneka kuthathelwe ingqalelo ukuba xa uthatha i-primer, inani lamaxesha kunye nexesha i-primer idibanisa umoya kufuneka iyancipha kangangoko kunokwenzeka. Kungcono ukusebenzisa ibhotile encinci yokuguqula ukupakisha.
3) Isitofu se-sealant
Emva kwesitofu seglue, i-sealant echasene nemozulu ayinakusetyenziswa ngokukhawuleza ngaphandle, ngaphandle koko, isantya sokunyanga se-sealant yesakhiwo siya kuncitshiswa kakhulu.
4) Ukucheba
Emva kokuba i-injection yeglue igqityiwe, ukunqumla kufuneka kuqhutywe ngokukhawuleza, okuhambelana noqhagamshelwano phakathi kwe-sealant kunye necala le-interface.
5) Ukurekhoda kunye nokumakishwa
Emva kokuba le nkqubo ingentla igqityiwe, bhala phantsi kwaye umakishe ngexesha.
6) Ugcino
Iyunithi kufuneka iphiliswe ixesha elaneleyo phantsi kweemeko ezimileyo kunye nezingagxininisi ukuze kuqinisekiswe ukuba i-sealant yesakhiwo inokubambelela okwaneleyo.
Ulandelelwano lolwakhiwo lwe-sealant yokumelana nemozulu kunye nomnyango kunye nesitywini sefestile:
1) Ulungiselelo oludibeneyo lwe-Sealant
Intonga ye-foam edibanisa ne-sealant kufuneka igcinwe ilungile. Iqondo lokushisa liphezulu ehlotyeni, kwaye ukuba intonga ye-foam iyonakalisiwe, kulula ukubangela i-blistering; ngelo xesha, ingqalelo kufuneka ihlawulwe ukuhambelana kwe-substrate kunye ne-sealant.
2) Coca i-substrate
I-glue edibeneyo kufuneka ihlambuluke kwindawo yokususa uthuli, ioli, njl.
3) Faka iprimer (ukuba kuyimfuneko)
Okokuqala, qiniseka ukuba ubuso be-glue joint substrate yome ngokupheleleyo. Ehlotyeni, ubushushu kunye nokufuma kuphezulu, kwaye i-primer i-hydrolyzed ngokulula emoyeni kwaye ilahlekelwa ngumsebenzi wayo. Kufuneka kuqatshelwe ukuba iglue kufuneka ifakwe ngokukhawuleza emva kokuba i-primer isetyenziswe. Ngexesha elifanayo, kufuneka kuqatshelwe ukuba xa uthatha i-primer, inombolo kunye nexesha lokuqhagamshelana nomoya kufuneka lincitshiswe kangangoko kunokwenzeka. Kungcono ukusebenzisa ibhotile encinci yokuguqula ukupakisha.
4) Isitofu se-sealant
Zininzi iindudumo ehlotyeni. Qaphela ukuba emva kwemvula, i-glue edibeneyo kufuneka yome ngokupheleleyo ngaphambi kokutofa iglue.
5) Ukugqiba
Iqondo lokushisa ehlotyeni liphezulu, kwaye ixesha lokugqiba lifutshane kunamanye amaxesha onyaka. Emva kokuba isitofu seglue sigqityiwe, ukugqitywa kufuneka kuqhutywe ngokukhawuleza.
6) Ugcino
Kwinqanaba lokuqala lokugcinwa, akufanele kubekho ukufuduka okukhulu.
Iingxaki eziqhelekileyo, indlela yokujongana nazo:
1. Ixesha elifutshane lekhefu le-sealant ye-structural sealant yamacandelo amabini
Isigwebo: Ixesha lekhefu lifutshane kunomda osezantsi wekhefu lekhefu elicetyiswa ngumenzi.
Isizathu: Ubushushu obuphezulu kunye nokufuma ehlotyeni kuyalinciphisa ixesha lekhefu.
Isisombululo: Lungisa umlinganiselo wamacandelo A no-B phakathi koluhlu olucetyiswa ngumenzi.
2. Ukungasebenzi kwe-primer sealant yesakhiwo
Isizathu: Ubushushu obuphezulu kunye nomswakama ehlotyeni, ukusetyenziswa ngokungafanelekanga kwe-primer kunokulahlekelwa lula ngumsebenzi wayo. I-primer engasebenziyo iya kukhokelela ekudibaneni kakubi kwe-structural sealant.
Isisombululo: Kungcono ukusebenzisa iibhotile ezincinci kwi-primer. Akukhuthazwa ukusebenzisa i-primer engasetyenziswanga kwibhotile engaphantsi kobusuku. Ngexesha elifanayo, kufuneka kuqatshelwe ukuba xa uthatha i-primer, inani kunye nexesha loqhagamshelwano phakathi kwe-primer kunye nomoya kufuneka lincitshiswe kangangoko kunokwenzeka. Kwaye khangela ubume be-primer kwi-sub-bhotile ngexesha. Ukuba ukubonakala kutshintshile ngenxa yexesha elide lokugcina, i-primer kwi-bottle-bottle akufanele isetyenziswe.
3. I-Weathering sealant / ucango kunye nefestile ye-sealant evuzayo
Indlela yesigwebo: Kukho amaqhuqhuva asekuhlaleni kumphezulu we-silicone sealant. Xa umcu onyangisiweyo usikiwe wavuleka, ngaphakathi akukho nto.
Isizathu ①: Umphezulu wentonga ye-foam uhlatywa ngexesha lokuzaliswa, kwaye umoya uphuma emngxunyeni emva kokucinywa;
Isisombululo: Icala lentonga yogwebu elidibene nesitywina lihlala linjalo. Ukuba kunzima ukuzalisa, unokusika inxalenye yomva wentonga ye-foam.
Isizathu ②: Ezinye ii-substrates zisabela ngezitywini;
Isisombululo: Nika ingqalelo ukuhambelana kweentlobo ezahlukeneyo ze-sealants kunye ne-substrates, kunye neemvavanyo zokuhambelana ziyafuneka.
Isizathu ③: Ukugquma okubangelwa kukwanda kwerhasi kwindawo etywiniweyo yeglu;
Isizathu esithile sinokuthi kuyo yonke i-glue evaliweyo edibeneyo, umoya otywinwe kwi-glue edibeneyo emva kokutofa uyanda ngomthamo xa ubushushu buphezulu (ngokubanzi ngaphezu kwe-15 ° C), kubangela ukugquma kumphezulu we-sealant engekafiki. iqinisiwe.
Isisombululo: Kuphephe ukutywinwa ngokupheleleyo kangangoko kunokwenzeka. Ukuba kuyimfuneko, shiya icandelo elincinci lemingxuma yokuphuma kwaye ugcwalise emva kokuba i-sealant iqina.
Isizathu ④: I-interface okanye i-accessory imathiriyeli imanzi;
Isisombululo: Musa ukwakha ngeentsuku zemvula, linda de imozulu icace kwaye i-glue edibeneyo yomile.
Isizathu ⑤: Ukwakhiwa phantsi kweemeko eziphezulu zokushisa ngaphandle;
Isisombululo: Misa ukwakhiwa phantsi kweemeko eziphezulu zokushisa ngaphandle kwaye ulinde de ukushisa kwehle ngaphambi kokwakhiwa.
4. Ixesha elifutshane lokulungiswa kwe-sealant echasene nemozulu / umnyango kunye nefestile yefestile
Isizathu: Ubushushu kunye nokufuma kuphezulu ehlotyeni, kwaye ixesha lokutsala lifutshane.
Isisombululo: Lungisa kwangethuba emva kokutofa.
Qaphela ngexesha lokwakha kwaye ulandele imiyalelo yokuqinisekisa umgangatho.
Ubushushu obuphezulu kunye nemvula enkulu yimingeni emikhulu, kwaye kukho amaqhinga okwakhiwa kwe-sealant.
Ukujongana neengxaki ngexesha elifanelekileyo ukuqinisekisa ukhuseleko lweprojekthi.
I-SIWAY ikukhapha ehlotyeni kwaye ixhobisa ubuhle kunye!
