Yintoni i-silicone yesakhiwo?

I-silicone structural sealant yi-neutral coating structure adhesive eyenzelwe ngokukodwa ukuhlanganisana kwesakhiwo ekwakheni iindonga zekhethini. Ingakhutshwa ngokulula kwaye isetyenziswe kwiimeko ezahlukeneyo zobushushu, kwaye inyangwa ibe yi-modulus ephezulu, eqinileyo, irabha ye-silicone ethambileyo ephezulu ngokufuma emoyeni. Kudonga lwekhethini leglasi, isetyenziselwa izinto zokuncamathelisa ze-silicone structure phakathi kwepleyiti kunye nesakhelo sesinyithi, ipleyiti kunye nepleyiti, kunye nepleyiti kunye nembambo yeglasi. Yinto ephambili yoxinzelelo lwesakhelo esifihliweyo kunye nodonga lwekhethini lwesakhelo esifihliweyo, kwaye ikwayinto ebalulekileyo echaphazela ukhuseleko lodonga lwekhethini leglasi. Ineempawu zokuxhathisa i-UV, ukuxhathisa i-ozone, ukuxhathisa okuhle kwemozulu kunye nokunamathela okunamandla. Ngaphambi kokusetyenziswa, kufuneka kwenziwe uvavanyo lokuhambelana lweglasi, isakhelo sesinyithi, i-spacer, i-gasket, ibhloko yokubeka kunye nezinye izitywina, kwaye uvavanyo lokuhambelana lungasetyenziswa kuphela emva kokuphumelela uvavanyo.
Ulwahlulo

Isakhiwo seSilicone sokuSebenza okuphezuluIsitywini
Le mveliso inokuvelisa ukunamathela okuhle kakhulu kwizinto ezininzi zokwakha ngaphandle kweprimer.
Ineempawu zemveliso ezibalaseleyo ezilandelayo:
1. Kulula ukuyisebenzisa: Ingakhutshwa kwaye isetyenziswe nangaliphi na ixesha.
2. Ukucoca okungathathi cala: kufanelekile uninzi lwezixhobo zokwakha ezingenazo iziphumo ezibi okanye ukugqwala.
3. Ukunamathela okugqwesileyo: akukho primer ifunekayo, kwaye inokwenza ukunamathela okuqinileyo kwizinto ezininzi zokwakha.
4. Uzinzo oluhle kakhulu lokulwa nokwaluphala.
5. Emva kokunyanga, inokusebenza okuphezulu kwe-modulus kwaye inokuthwala ukwandiswa kunye nomthamo wokufuduka we-±25% yojongano.
6. Kwindibano yesakhiwo, iisampulu zezinto kunye nemizobo yendibano kufuneka zithunyelwe kwinkampani yovavanyo yobungcali ukuze zivavanywe kwaye zihlolwe kwangaphambili.
 
Isitywina sesakhiwo se-silicone esicacileyo nesingathathi cala
Inxalenye enye, ukunyibilikisa okungathathi cala, eyenzelwe ngokukodwa ukuhlanganiswa kwezakhiwo zeglasi kwiindawo ezingaphambili zezakhiwo. Ingakhutshwa lula kwaye isetyenziswe kwiimeko ezahlukeneyo zobushushu. Ixhomekeke kumswakama emoyeni ukuze inyibilike ibe yirabha ye-silicone egqwesileyo, eqinileyo, ethambileyo nethambileyo. Imveliso ayidingi primer kwiglasi, kwaye inokuvelisa ukunamathela okuhle kakhulu. Ineempawu ezilandelayo zemveliso ezibalaseleyo:
1. Kulula ukuyisebenzisa: ingakhutshwa kwaye isetyenziswe nangaliphi na ixesha
2. Unyango olungathathi cala: akukho mpembelelo kumaleko weglasi oqinisiweyo
3. Ukunamathela okugqwesileyo;
4. Uzinzo oluhle kakhulu lokulwa nokwaluphala;
5. Emva kokunyanga, inokusebenza okuphezulu kwe-modulus kwaye inokuthwala ukwandiswa kunye nomthamo wokufuduka we-±25% yojongano;
6. Kwindibano yesakhiwo, iisampulu zezinto kunye nemizobo yendibano kufuneka zithunyelwe kwinkampani yovavanyo yobungcali ukuze zivavanywe kwaye zihlolwe kwangaphambili.

Disivakalisi
Umahluko phakathi kwesakhiwoisitywinikunye nokungabi nasakhiwoisitywini
I-structural sealant ibhekisa kumandla aphezulu (amandla oxinzelelo> 65MPa, amandla okubopha okutsalwa kwentsimbi-intsimbi> 30MPa, amandla okucheba> 18MPa), inokumelana nemithwalo emikhulu, kwaye iyamelana nokwaluphala, ukudinwa, ukugqwala, kunye nokusebenza ngaphakathi kobomi obulindelweyo. Izinzile, ifanelekile kwi-structural bonding eqinileyo.
Isitywini esingesosakhiwo sinamandla aphantsi kwaye asihlali ixesha elide, kwaye sinokusetyenziselwa kuphela ukubopha okuqhelekileyo nokwexeshana, ukutywina, kunye nokulungisa, kwaye asinakusetyenziswa ukubopha okusesakhiwo.
Ubomi benkonzo yeeprojekthi zokwakha ngokubanzi bungaphezulu kweminyaka engama-50, kwaye izinto ezisetyenzisiweyo zinoxinzelelo olukhulu nolunzima, oluhambelana ngqo nokhuseleko lwabasebenzi kunye nepropathi. Izincamathelisi zesakhiwo zisetyenziswa kakhulu kubunjineli, zisetyenziselwa ukuqinisa, ukubambelela, ukubopha, ukulungisa, njl. njl. ukubopha, njl.
