USHWANKATHELO
Ukhetho oluchanekileyo lwe-sealant kufuneka luthathele ingqalelo injongo yejoyinti, ubungakanani be-joint deformation, ubungakanani bomdibaniselwano, i-joint substrate, indawo apho unxibelelwano oludibeneyo, kunye neempawu zomatshini ekufuneka isitywini sifezekiswe. . Phakathi kwabo, ubungakanani bomdibaniselwano buchongwa luhlobo lokudibanisa kunye nobukhulu obulindelekileyo be-deformation edibeneyo.
Ukuqinisekisa ubomi benkonzo obugqwesileyo kunye nokusebenza kwe-sealant, ukhetho oluchanekileyo lwe-sealant kufuneka luqwalaselwe ngokucophelela. Ngokuqhelekileyo, amanyathelo amathathu anokuthathwa ukuqinisekisa ukuba i-sealant ifikelela kubomi bayo boyilo obulungileyo.
- 1. Yila imithungo ngokwenzululwazi nangengqiqo ngokweemfuno zokusetyenziswa kunye nokusingqongileyo;
- 2. Qinisekisa izibonakaliso zokusebenza ukuba i-sealant idinga ukuhlangabezana ne-interface eyilelwe;
- 3. Ngokusekelwe kwizibonakaliso zokusebenza ezimiselweyo, kucetyiswa ukuba ukhethe i-adhesive kwaye uqhube ukuhambelana okufunekayo kunye neemvavanyo zokubambelela ukuqinisekisa ukuba imveliso ekhethiweyo ihlangabezana neemfuno.
Izitywini zokwakha zenza le misebenzi mithathu ilandelayo ngenkqubo yokudibanisa:
- 1. Ukukwazi ukugcwalisa umsantsa phakathi kwee-substrates ezimbini okanye ngaphezulu ukwenza itywina:
- 2. Ukwenza umqobo ngokusebenzisa iipropati zayo zomzimba kunye nokunamathela kwi-substrate
- 3. Gcina ukuqina kokutywina phantsi kobomi obulindelekileyo, iimeko zokusebenza kunye nokusingqongileyo.
Izinto eziphambili ezimisela umsebenzi we-sealant zibandakanya amandla okunyakaza, iimpawu zomatshini, ukunamathela, ukuqina, kunye nokubonakala. Iipropathi zoomatshini nezoomatshini ikakhulu zibhekisa kwizalathisi ezinje ngokuqina, imodyuli enwebekayo, ukomelela kokuqina, ukuxhathisa ukukrazuka, ukuqina, kunye nesantya sokubuya kwe-elastiki. Xa ufaka i-sealant, eyona mfuno iphambili yokusetyenziswa ekufuneka ithathelwe ingqalelo lixesha le-tack free, ixesha lokuzibophelela, ukudilika, ubomi beshelufa (yezinto ezincamathelayo ezinamacandelo amabini), ukuqina, isantya esinzulu sokuphilisa, ukungaphumi ugwebu, iindleko, umbala, kunye nokuncipha komda ngexesha. ukunyanga Kwangaxeshanye, kuyafuneka ukuba kuqwalaselwe iipropathi zokuguga ze-sealant, kubandakanywa ukuxhathisa kwayo kwimitha ye-UV, iipropathi ezinobushushu obuphezulu kunye nobushushu obuphantsi, i-thermal hydrolysis, ukuguga kwe-thermal, kunye nokumelana ne-oxidation.
Ukunamathela yinkqubo ebandakanya ukulungiswa, ukusetyenziswa, ukunyanga, kunye nokugcinwa kwe-sealant. Umgangatho wokusebenza okuncamathelisayo uhambelana ngokuthe ngqo kwizinto ezidibeneyo, i-sealant, kunye nenkqubo yokubambelela. Ngoko ke, xa kusenziwa ukwakhiwa, impembelelo yezinto ezintathu kufuneka iqwalaselwe ngokubanzi. Kuphela ngokulungelelanisa izinto ezintathu ngokufanelekileyo kunye nokudibanisa ngokwemvelo kunokufezekiswa ukunamathela okufanelekileyo, kwaye nayiphi na ingxaki kuyo nayiphi na ikhonkco inokukhokelela ekungaphumelelini kokubambelela.
I-Silicone sealant esetyenziswa kulwakhiwo ikakhulu ibonelela ngokutywinwa kokumelana nemozulu kunye nokutywinwa kolwakhiwo. Ukongeza kuyilo olululo lojongano, imigaqo ehambelanayo yenkqubo yokwakha kufuneka nayo ilandelwe ngexesha lenkqubo yokwakha.
Kukho iimfuno ezisisiseko ezintlanu zokulungiswa komphezulu ochanekileyo kunye nokuncamathelisa:
- Umphezulu wojongano kufuneka ucoceke, wome, ungabinathuli kunye neqabaka;
- Ukuba i-primer iyadingeka, kufuneka isetyenziswe kwindawo ecocekileyo;
- Sebenzisa i-back-back-back materials okanye i-adhesive tape njengoko kufuneka;
- Xa usebenzisa i-sealant, kuyimfuneko ukuzalisa i-gap ye-interface kunye ne-sealant;
- Ukukhuhla kukuqinisekisa i-seams egudileyo, imilo echanekileyo, kunye noqhagamshelwano olupheleleyo kunye ne-substrate.
I-Silicone sealant nayo inokuthathwa njengento yokubambelela ngenxa yesakhiwo sayo sekhemikhali. Ukutywinwa kokutywinwa kwe-Silicone yindlela yendalo yeekhemikhali, ngoko ke amanyathelo achanekileyo okusetyenziswa abaluleke kakhulu. Ngenxa yokusetyenziswa kwe-OLIVIA i-silicone sealant kwiindawo ezininzi ezahlukeneyo kunye neemeko, ukucaciswa kwenkqubo yokwakha akunakuthathwa njengenkqubo epheleleyo kunye neyongezelelweyo yokuqinisekisa umgangatho. Ulawulo lomgangatho wolwakhiwo kufuneka lwenziwe, kwaye uvavanyo lwe-adhesive kwisiza kufuneka lwenziwe ukuze kuqinisekiswe amandla ancamatheleyo alungileyo kwaye kuqinisekiswe naziphi na iingcebiso malunga nokuncamathelisa.
Ekulawuleni umgangatho wokwakhiwa kwe-sealant, ukunamathela kunye nokuhambelana kwe-sealant kunye nesiseko sezinto kufuneka kuthathelwe ingqalelo, kubandakanywa intonga exhasayo, i-tape strip ephindwe kabini kunye nezinye izinto ezincedisayo. Ukwandisa ukusebenza okuphezulu kwe-silicone sealant, kuyafuneka ukuba ukhethe ii-silicone sealants ezahlukeneyo ngokusekelwe kwiindawo ezahlukeneyo zokwakha, iimfuno, kunye nezixhobo, kunye neendlela zokwakha ezisemgangathweni. Ubuchule bokwakha obungavumelekanga buhlala bunciphisa ukusebenza okuphezulu kwe-sealants, njengokucoca umphezulu we-substrate, inani le-primer esetyenzisiweyo, i-aspect ratio engafanelekanga, ukuxuba ukungalingani kwezinto ezimbini zokutywinwa, kunye nokusetyenziswa kwe-solvents okanye iindlela ezichanekileyo zokucoca, ezinokuchaphazela. ukuncamathelwa kwezitywina kunye nokukhokelela ekungaphumelelini kokuncamathelisa, njengokukhetha okuncamathelayo okungafanelekanga okukhokelela kumaqamza kunye nokuguquka kombala we-sealant. Ngoko ke ukukhethwa kwe-sealant kunye nokuchaneka kwenkqubo yokwakha kubalulekile. Ngokuzisa le misebenzi, inokunceda ukukhetha i-sealant efanelekileyo ngokuchanekileyo.
Itywina elingangenwa ngamanzi kunye nemozulu
Ezinye ii-non-silicone sealants zivame ukuguga ngokuhamba kwexesha kwaye ziphantsi kweempembelelo zezinto ezinobungozi kwindalo, ngakumbi phantsi kwemitha ye-ultraviolet. Ngoko ke, xa ukhetha i-sealant, ubomi benkonzo ye-sealant kufuneka buqwalaselwe. Ukutywinwa okungangeni manzi kusetyenziselwa ukuzalisa izikhewu phakathi kwezinto zokuthintela umoya, imvula, uthuli, njl. Ngoko ke, i-sealant kufuneka ibambelele ngokupheleleyo kwi-substrate, ukwenzela ukuba ikwazi ukunqoba utshintsho kubukhulu obudibeneyo obubangelwa ukunyakaza kwe-substrate ngexesha lokwandiswa okanye ukunyanzeliswa. I-OLIVIA i-silicone sealant inokumelana ne-UV elungileyo, inokugcina imodyuli engatshintshiyo, kwaye ukuqina kwayo akuguquki kuluhlu lobushushu obuphakathi kwe -40 ℃ ukuya +150 ℃.
Izitywini zokusebenza ezisezantsi zisetyenziswa ikakhulu ukuvala izikhewu phantsi kweemeko ezisisiseko ezimile ukuthintela ukungena kothuli, imvula kunye nomoya. Nangona kunjalo, ukucutheka okugqithisileyo, ukuqina ngokuhamba kwexesha, kunye nokubambelela kakubi kunokuchaphazela ukusebenza kwabo. Ukuhambelana, ukunamathela, kunye nefuthe lemichiza kufuneka kuthathelwe ingqalelo xa uzisebenzisa.
Itywina loLwakhiwo
I-sealant esetyenziselwa ukutywinwa kwesakhiwo ibambelela ngokukodwa kwiindidi ezimbini ze-substrates. Kwangaxeshanye, inokoyisa uxinzelelo olufunyenweyo: uxinzelelo kunye noxinzelelo loxinzelelo, uxinzelelo lwe-chear. Ngoko ke, ngaphambi kokutywinwa, amandla okwakhiwa kwala malungu kufuneka aqinisekiswe, ukuze abonakaliswe ngobuninzi xa kubalwa iimfuno zobunjineli. Amandla okwakhiwa abonakaliswa ngokwemodyuli kunye namandla okuqina. Izitywini zesakhiwo kufuneka zifikelele kwinqanaba elithile lamandla. Enye imeko ebalulekileyo yokutywinwa kwesakhiwo kukuba ukudibanisa phakathi kwetywina kunye ne-substrate akonakali ngokuhamba kwexesha. I-OLIVIA i-silicone structural sealants inomsebenzi othembekileyo, ubomi obude benkonzo, kwaye ifanelekile ukutywinwa kwesakhiwo.
Izilumkiso zokuKhetha isitywina seSilicone soKwakha
Ukhetho oluchanekileyo lwe-sealant alubandakanyi kuphela ukukhetha izixhobo ezineempawu ezifanelekileyo zomzimba kunye neekhemikhali, kodwa ziqwalasela uhlobo kunye neempawu ze-substrate yokutywina, uyilo oludibeneyo (kubandakanya inkxaso okanye izinto ezifakwe ngaphakathi), ukusebenza okulindelekileyo, iimfuno zemveliso, kunye neendleko ezisebenzayo ngokwezoqoqosho. iindleko, zonke ziqwalaselwe. Uluhlu olulandelayo lusetyenziswa ngokuqhelekileyo kwishishini lokwakha ukukhetha izitywini.
