Iyini i-Polyurethane Foam Sealant esetshenziselwa yona?
Isivali se-foam se-polyurethaneiyinto eguquguqukayo esetshenziselwa izinhlelo ezahlukene, ikakhulukazi ekwakheni nasekuthuthukiseni ikhaya. Nazi ezinye zezindlela ezivamile zokusebenzisa:
Ukuvala:Ihlinzeka ngokuvikela ukushisa okuhle kakhulu, okusiza ukunciphisa izindleko zamandla ngokuvimbela ukulahleka noma ukwanda kokushisa ezakhiweni.
Ukuvalwa Komoya:Igwebu liyakhula lapho lisetshenziswa, ligcwalisa izikhala kanye nemifantu ezungeze amafasitela, iminyango, kanye nezinye izimbobo, okusiza ukuvimbela umoya ophumayo futhi kuthuthukiswe ikhwalithi yomoya wangaphakathi.
Ukuvimbela umsindo:Kungasiza ekunciphiseni ukudluliswa komsindo phakathi kwamakamelo noma ngaphandle, okwenza kube usizo ezinhlelweni zokuvimbela umsindo.
Isithiyo Somswakama:I-polyurethane foam ingasebenza njengesivikelo sokumelana nomswakama, isize ekuvimbeleni ukungena kwamanzi kanye nomonakalo ongaba khona ngenxa yesikhunta kanye nesikhunta.
Ukusekelwa Kwesakhiwo:Kwezinye izimo,I-PU Foam sealantinganikeza ukwesekwa okwengeziwe kwesakhiwo, ikakhulukazi ezindaweni lapho kudingeka khona izinto ezilula.
Ukugcwalisa Izikhala Nemifantu:Isebenza kahle ekugcwaliseni izikhala ezinkulu kanye nezimbobo ezindongeni, phansi, kanye nophahla, kanye nasezindaweni ezizungezile amapayipi kanye nokungena kukagesi.
Ukufaka Nokunamathela:Ingasetshenziswa ukubopha izinto endaweni yazo, njengezinsika zamafasitela, izinsika zeminyango, nezinye izinto ezisetshenziswayo.
Ukulawulwa Kwezinambuzane:Ngokuvala izindawo zokungena, kungasiza ekuvimbeleni izinambuzane ukuthi zingangeni esakhiweni.
Yini i-Pu Foam Enganamatheli Kuyo?
I-polyurethane foam sealant yaziwa ngezakhiwo zayo eziqinile zokunamathela, kodwa kunezinto ezithile kanye nezindawo ezinganamatheli kahle noma ezinganamatheli nhlobo kuzo. Nazi ezinye izibonelo ezivamile:
I-Polyethylene ne-Polypropylene:Lawa mapulasitiki anamandla aphansi omhlaba, okwenza kube nzima ukuthi i-PU foam ihlangane kahle.
I-Teflon (PTFE):Le nto enganamatheli yenzelwe ukuxosha izinto zokunamathela, okuhlanganisa ne-PU foam.
I-Silicone:Nakuba i-PU foam inganamathela kwezinye izindawo ze-silicone, ngokuvamile ayihlangani kahle ne-silicone sealants evuvukile.
Izindawo Ezinamafutha Noma Ezinamafutha:Noma yiluphi uhlangothi olungcoliswe uwoyela, amafutha, noma i-wax lungavimbela ukunamathela okufanele.
Izimbozo ezithile:Amanye amapende, ama-varnish, noma ama-sealant angadala isithiyo i-PU foam engakwazi ukunamathela kuso ngempumelelo.
Izindawo Ezibushelelezi, Ezingenazo Izikhala:Izindawo ezibushelelezi kakhulu, njengengilazi noma izinsimbi ezicwebezelisiwe, zingase zinganikezi ukuthungwa okwanele ukuze igwebu libambe.
Izindawo Ezimanzi Noma Ezimanzi:Ifoam ye-PU idinga indawo eyomile ukuze inamathele kahle; ukuyisebenzisa ezindaweni ezimanzi kungaholela ekubophweni okungekuhle.
Isicelo se-PU Foam
1. Kungcono kakhulu ukufaka amaphaneli okushisa nokugcwalisa izikhala ngesikhathi sokufaka i-glue.
2. Kuyelulekwa ukuthi izinto zokwakha zohlobo lwezinkuni zinamathele kukhonkrithi, insimbi njll.
3. Izinhlelo zokusebenza bezidinga ukunwetshwa okuncane.
4. Ukufakwa kanye nokwahlukaniswa kwamafreyimu amafasitela neminyango.
Izici
Luhlobo olulodwa, olungabizi futhi olusebenza kahle. Lufakwe ikhanda le-adaptha yepulasitiki ukuze lusetshenziswe nesibhamu sokufaka i-foam noma utshani. I-foam izokhula futhi iphole ngenxa yomswakama emoyeni. Isetshenziselwa izinhlelo zokusebenza eziningi zokwakha. Ilungele kakhulu ukugcwalisa nokuvala ngamandla amahle okufaka, ukushisa okuphezulu kanye nokuvikela umsindo. Ivikela imvelo njengoba ingenayo impahla ye-CFC.

Uyini Umehluko Phakathi Kwe-Pu Sealant Ne-Silicone Sealant?
Umehluko phakathi kwe-polyurethane (PU) sealant kanye ne-silicone sealant ubalulekile, njengoba uhlobo ngalunye lunezakhiwo zalo ezihlukile kanye nezinhlelo zokusebenza ezifanelekile. Nansi umehluko oyinhloko:
1. Inqubo Yokwakheka Nokwelapha:
Isivali se-PU: Yenziwe nge-polyurethane, yelapha ngokusabela kwamakhemikhali okunomswakama emoyeni. Ngokuvamile iyakhula lapho isetshenziswa, igcwalisa izikhala ngempumelelo.
I-Silicone Sealant: Yenziwe ngama-silicone polymers, iyaphola ngenqubo ebizwa ngokuthi “i-neutral curing,” engadingi umswakama. Ihlala iguquguquka ngemva kokuphola.
2. Ukunamathela:
I-PU Sealant: Ngokuvamile inokunamathela okuhle kakhulu ezinhlotsheni eziningi ze-substrate, okuhlanganisa ukhuni, insimbi, kanye nokhonkolo. Inganamathela kahle ezindaweni ezinezimbobo kanye nezingenazimbobo.
I-Silicone Sealant: Inamathela kahle ezindaweni eziningi, kodwa ukunamathela kwayo kungase kungasebenzi kahle ezintweni ezithile ezifana nepulasitiki noma izindawo ezinamafutha.
3. Ukuzivumelanisa nezimo kanye nokunyakaza:
Isivali se-PU: Inikeza ukuguquguquka okuhle kodwa ingaba nokunwebeka okuncane kune-silicone. Ifanele ukusetshenziswa lapho ukunyakaza okuthile kulindeleke khona kodwa kungase kungabi nokunyakaza okukhulu kanye ne-silicone.
I-Silicone Sealant: Iguquguquka kakhulu futhi ingamelana nokunyakaza okukhulu ngaphandle kokuqhekeka noma ukulahlekelwa ukunamathela, okwenza kube kuhle kakhulu emalungeni athola ukunwebeka nokufinyela.
4. Ukuqina kanye nokumelana nesimo sezulu:
I-PU Sealant: Ngokuvamile imelana nokukhanya kwe-UV kanye nesimo sezulu esibi, kodwa ingawohloka ngokuhamba kwesikhathi uma ivezwa elangeni eliqondile ngaphandle kokugqoka okuyisivikelo.
I-Silicone Sealant: Izakhiwo ezinhle kakhulu zokumelana ne-UV kanye nokuvikela isimo sezulu, okwenza ifaneleke ukusetshenziswa ngaphandle. Ayiboli ngokushesha uma ibhekene ne-UV.
5. Ukumelana Nokushisa:
I-PU Sealant: Ingamelana nokushisa okuhlukahlukene kodwa ingase ingasebenzi kahle ekushiseni okukhulu noma ekubandeni uma kuqhathaniswa ne-silicone.
I-Silicone Sealant: Ngokuvamile inokubekezelela amazinga okushisa abanzi, okwenza ifaneleke ukusetshenziswa kwamazinga okushisa aphezulu.
6. Izicelo:
I-PU Sealant: Ivame ukusetshenziswa ekwakheni, ekushiseni, nasekuvaleni izikhala ezindongeni, ophahleni, nasemafasiteleni nasezicabheni ezizungezile.
I-Silicone Sealant: Ivame ukusetshenziswa ezindlini zangasese, ekhishini, nakwezinye izindawo lapho ukumelana namanzi kubalulekile khona, njengokuvala eduze kwezinki, amabhavu, kanye neshawa.
7. Ukupendwa:
I-PU Sealant: Ingapendwa kaningi uma isilungisiwe, okwenza ifaneleke ukusetshenziswa lapho ubuhle bubalulekile khona.
I-Silicone Sealant: Ngokuvamile ayipendi, njengoba upende unganamatheli kahle ezindaweni ze-silicone.
