Iindaba-Ithini i-Polyredthane Fiam esetyenziselwa ntoni? Umahluko phakathi kwe-pulelant kunye ne-silicone elwandle

Yintoni i-Polyredthane itywina elisetyenziselwa?

I-Polyurethane Fiam SealantIsixhobo esiguquguqukayo esisetyenziselwa ukusetyenziswa kwezicelo ezahlukeneyo, ngokuyintloko kulwakhiwo nasekuphuculeni nasekhaya. Nantsi into eqhelekileyo esetyenziswayo:

Ukufakwa:Inika ukufudumeza ngokugqibeleleyo, inceda ukunciphisa iindleko zamandla ngokuthintela ilahleko yobushushu okanye inzuzo kwizakhiwo.

Ukutywinwa komoya:I-foam iyakhula kwisicelo, ukuzalisa izithuba kwaye ijikeleze iifestile, iingcango, kunye nezinye iindawo ezivulekileyo, ezinceda ekuthinteleni uyilo kunye nokuphucula umgangatho womoya ongaphakathi.

I-POPROFOOOOOOOOF:Inganceda ukunciphisa ukuhanjiswa kwengxolo phakathi kwamagumbi okanye ngaphandle, kwenza kube lula kwizicelo ezivakalayo.

Ukufuma terriers:I-Polyurethane Foam inokusebenza njengesithintelo ngokuchasene nokufuma, incedise ukuthintela ukungena kwamanzi kunye nomonakalo onokubakho ovela kwi-mold kunye ne-maildew.

Inkxaso yesakhiwo:Ngamanye amaxesha,I-puning ceam enyaweniUnokubonelela ngenkxaso eyongezelelweyo yezakhiwo, ngakumbi kwiindawo apho kufuneka khona izinto ezilula.

Gcwalisa izithuba kunye nee-rocks:Isebenza ngokuzalisa izithuba ezikhulu kunye neendonga ezindongeni, imigangatho, kunye nophahla, kunye nokuziphambana kombane kunye nokungena kombane.

Ukunyuka kunye nokunamathela:Ingasetyenziselwa ukukhusela izinto, ezinje ngemikhombandlela yefestile, izakhelo zomnyango, kunye nezinye izinto ezilungisiweyo.

Abalawuli berhorho:Ngamanqaku okutywina, kunokunceda iindawo zokungena kwisakhiwo.

Ingaba unamathele ntoni i-puam?

I-Polyurethane (pu) i-foam itywina yaziwa ngokuba ziimpawu zayo zobuqili, kodwa zikho izinto ezithile kunye nendawo engaphantsi kwazo ukuba ayihambelani kakuhle okanye ingayi kubambeleli kwaphela. Nantsi imizekelo eqhelekileyo:

I-Polythylene kunye nePolypropylene:Ezi playitics zinamandla aphantsi, zenza kube nzima kwi-pum ukuya kwi-chbond.

I-TFNLO (PTFE):Le mpahla inganamathengo yenzelwe ukuphelisa amanye amachaphaza, kubandakanya i-pum foam.

Silicone:Ngelixa u-pull unokubambelela kwindawo ethile ye-silicone, ngokubanzi ayibonwabi kakuhle ukuba iphilise itywina le-silicone.

I-oily okanye i-Greisy Restoy:Nawuphi na umphezulu ongcoliswe yioyile, igrisi, okanye i-wax inokuthintela ukubambelela ngendlela efanelekileyo.

Iingubo ezithile:Ezinye iipeyinti, ii-varnish, okanye izityholo zinokwenza umqobo ukuba i-pumple ye-pull ayinakho ukubambelela ngokufanelekileyo.

Ifihlakeleyo, engacocekanga:Indawo egudileyo egudileyo, njengeglasi okanye i-mellings engcolisekileyo, isenokunganikezeli ukuthungwa okwaneleyo kwigwebu.

Imanzi okanye indawo enamanzi:I-pull foam ifuna indawo eyomileyo yokunamathezeka ngokufanelekileyo; Ukuyisebenzisa kwimigangatho emanzi kungakhokelela ekuqhubeni kakubi.

Isicelo se-pum

1. Eyona nto ibalulekileyo ekukhuliseni iiphaneli zokugcina ubushushu kunye nokuzalisa i-voids xa kusenziwa isicelo.

2. Cebisa ngeZixhobo zokwakha ezenziwe ngomthi kwikhonkrithi yekhonkrithi, intsimbi njlnjl.

I-3. Izicelo zifuna ukwanda okuncinci.

4. Ukunyuka kunye nokuhlala yedwa kwizakhelo zeefestile neengcango.

Iimbonakalo

Licandelo elinye, uhlobo lwezoqoqosho kunye nendlela elungileyo yePolyurethane Fom. Ifakwe kwintloko ye-adaptha yeplastiki yokusetyenziswa kunye nompu osebenza umpu okanye umququ. I-foam iya kwanda kwaye iphiliswe ngokufuma emoyeni. Isetyenziselwa uluhlu olubanzi lwezicelo. Kuhle kakhulu ukugcwalisa nokutywina ngoncedo olupheleleyo lokukhwela, i-thermal ephezulu kunye ne-acoustical. Yisiseko sendalo njengoko inganayo nayiphi na into ye-CFC.

Nguwuphi umahluko phakathi kwe-puselant kunye ne-silicone elwandle?

Umahluko phakathi kwePolyurrethane (Pu) iSealant kunye ne-Silicone Selane iSelares ibalulekile, njengohlobo lwalunye lunezinto ezizodwa kunye nezicelo ezifanelekileyo. Nanga umahluko ophambili:

I-1. Ukuqulunqwa kunye nenkqubo yokunyanga:

I-PU Searlant: Yenziwe kwiPolyurethane, iphika ngokusabela kwikhemikhali enomswakama emoyeni. Ngokuqhelekileyo ukwanda kwisicelo, ukuzalisa izithuba ngokufanelekileyo.

I-Silicoone Sealant: eyenziwe kwi-silicone polymers, iphilisa ngenkqubo ebizwa ngokuba "kukungathathi cala," okungafuni ukufuma. Ihlala iguquka emva konyango.

2. Ubembise:

I-Pu Searlant: Ngokubanzi inesifo sokunamathela ngokugqwesileyo kwiintlobo ezahlukeneyo zamantshontsho, kubandakanya neenkuni, intsimbi, kunye nekhonkrithi. Inshunng kakuhle ukuya kumphezulu we-porous kunye ne-porous.

I-Silicone Sealant: Ikwanamathela emgceni, kodwa ukunamathela nzima kunokuba kusebenza ngezinto ezithile ezinjengeeplastiki okanye iindawo ezinamafutha.

I-3. Ukuguquguquka kunye nentshukumo:

I-PU Searlant: Inika ukuguquguquka okulungileyo kodwa kungaphantsi kwe-elastiki kune-silicone. Ilungele izicelo apho ikho intshukumo ilindelwe khona kodwa ayinakubamba intshukumo egqithisileyo kunye ne-silicone.

I-Silicone Sealant: Iguquguquka kakhulu kwaye ingayifumana intshukumo ebalulekileyo ngaphandle kokuqhekeza okanye ukuphulukana nokunamatheli, ukuyenza ilungele ukudibana kwawo amandla okukhula kunye nokuchasana.

I-4. Ukuqina kunye nokuxhathisa kwemozulu:

I-pulelant: ngokubanzi ukumelana nokukhanya kwe-Uv kunye nemozulu, kodwa inokudeka ixesha elide ukuba ityhilwe kwilanga elathatyathwayo ngaphandle kokuphela kwelanga.

I-Silicoone Sealant: Ukuchasana nokuchasana ne-UV ngokugqibeleleyo kunye neePropathi zeMozulu, zenza ilungele ukusetyenziswa kwangaphandle. Ayithathi hlazo ngokukhawuleza malunga nokuvezwa kwe-UV.

5. Ukuxhathisa ubushushu:

I-Pu Searlant: ingakwazi ukumelana novavanyo lwamaqondo obushushu kodwa akenzi ngokushushu kakhulu okanye ukubanda xa kuthelekiswa ne-silicone.

Isiliki se Selicone: Ngokwesiqhelo inonyamezelo lobushushu, owenza ilungele ukusetyenziswa kobushushu obuphezulu.

6. Izicelo:

I-Pu Searlant: isetyenziselwa ukwakhiwa, ukufudumala, nokutywina izithuba ezindongeni, eluphahleni, kunye neefestile kunye neengcango.

I-Silicone Sealant: ihlala isetyenziselwa igumbi lokuhlambela, ikhitshi, kunye nezinye iindawo apho ukuchaswa kwamanzi kubalulekile, njengokutywina, iityhubhu, kunye nemiboniso.

7. Ukupeyinta:

I-Pu Searlant: ingadla ngokupeyinta ngaphezulu kokuba kuphiliswe, iyenza ilungele izicelo apho i-aesthetics ibalulekile.

I-Silicoone Sealant: Ngokubanzi ayinakufane, njengoko ipeyinti ayihambelani kakuhle kwi-selicone.
