Yini i-polyurethane foam sealant esetshenziselwa yona?
Polyurethane foam sealantIngabe impahla eguquguqukayo esetshenziselwa izinhlelo ezahlukahlukene, ikakhulukazi ekwakhiweni nasekuthuthukisweni kwasekhaya. Nazi ezinye izinto ezijwayelekile:
Ukufakwa:Inikeza ukufakwa okuhle kakhulu okushisayo, ukusiza ukunciphisa izindleko zamandla ngokuvimbela ukulahleka kokushisa noma ukuzuza ezakhiweni.
Ukubekwa komoya:I-Foam ikhula lapho kufakwa isicelo, ukugcwalisa izikhala kanye nemifantu ezungeze amawindi, iminyango, nezinye izinto ezivulekile, ezisiza ukuvikela okusalungiswa futhi kuthuthukise ikhwalithi yomoya yangaphakathi.
Ukuzwakala kwe-Soundproofing:Kungasiza ukunciphisa ukudluliswa komsindo phakathi kwamakamelo noma kusuka ngaphandle, okwenza kube lusizo kuzinhlelo zokusebenza ezi-soundproofing.
Isithiyo sokuswakama umswakama:I-Polyurethane Foam ingasebenza njengesithiyo sokuphikisana nomswakama, isiza ukuvikela ukungena kwamanzi kanye nomonakalo ongaba khona kusuka kubumba nasensimini.
Ukuxhaswa Kwezinkampani:Kwezinye izimo,Pu Foam SealantAnganikeza ukwesekwa okwengeziwe kwesakhiwo, ikakhulukazi ezindaweni lapho kudingeka khona izinto ezingasindi.
Ukugcwalisa izikhala nokufakelwa:Kuyaphumelela ukugcwalisa izikhala ezinkulu kanye nama-voids ezindongeni, phansi, kanye nophahla, kanye nokungena kwamapayipi kanye nokungena kukagesi.
Ukukhwela kanye nokunamathelisa:Ingasetshenziswa ukuvikela izinto endaweni, njengamafreyimu wewindows, ozimele beminyango, nokunye ukulungiswa.
Ukulawulwa Kwezinambuzane:Ngokubopha amaphuzu amaphuzu wokungena, kungasiza ukunqanda izinambuzane ukuthi zingangeni esakhiweni.
Ngabe i-pu foam ayinamatheli?
I-Polyurethane (PU) I-Foam Sealant yaziwa ngezakhiwo zayo eziqinile zokunamathela, kepha kukhona izinto ezithile kanye nezindawo ezinganamathele noma zingakunamatheli nhlobo. Nazi ezinye izibonelo ezivamile:
Polyethylene ne-polypropylene:Lawa mapulasitiki anamandla aphansi, okwenza kube nzima nge-pu foam ukuyobumbana ngempumelelo.
Teflon (PTFE):Le mali engeyona induku yenzelwe ukunciphisa izinamathiseli, kufaka phakathi i-pu foam.
Abicone:Ngenkathi i-PU FOAM inganamathela ezindaweni ezithile ze-silicone, ngokuvamile ayihlanganisi kahle ekuphumeni ama-silicone sealants.
I-Oily noma indawo enamafutha:Noma yimuphi umphezulu ongcoliswe ngamafutha, amafutha, noma i-wax angavimba ukunamathela okufanele.
Imbolo ethile:Amanye amapende, ama-varnish, noma ama-sealants angakha isithiyo sokuthi u-pu foam akakwazi ukunamathela ngempumelelo.
Indawo ebushelelezi, engeyona eye-porous:Izindawo ezibushelelezi kakhulu, njengengilazi noma izinsimbi ezibunjiwe, zingahle zingakunikeli ukuthungwa okwenele kwegwebu ukuyobamba.
Izindawo ezimanzi noma ezinomswakama:I-PU FOAM idinga indawo eyomile yokunamathelisa okulungile; Ukuyisebenzisa ezindaweni ezimanzi kungaholela ekubopheni okumpofu.
Isicelo se-PU FOAM
1. Okuhle kakhulu ekukhuleni kokushisa kwamaphaneli wokufakelwa nokugcwalisa izikhala ngesikhathi sokunamathela.

Izici
Kuyinto eyodwa-ingxenye, uhlobo lwezomnotho kanye nokusebenza okuhle kwe-polyurethane foam. Ifakwe ngekhanda le-adaptha yepulasitiki ukuze isetshenziswe ngesibhamu sohlelo lokusebenza lwe-Foam noma utshani. Igwebu lizokwanda nokwelashwa ngomswakama emoyeni. Isetshenziselwa ukwahlulwa okuhlukahlukene kwezicelo zokwakha. Kuhle kakhulu ukugcwalisa nokubekwa uphawu ngamakhono amahle kakhulu akhuphukayo, ukufakwa okushisayo okushisayo kanye ne-acoustical. Kunobungani bezemvelo njengoba kungaqukethe noma yiziphi izinto ze-CFC.

Uyini umehluko phakathi kwe-pu sealant kanye ne-silicone sealant?
Umehluko phakathi kwe-polyurethane (pu) sealant kanye ne-silicone sealant kubalulekile, njengoba uhlobo ngalunye lunezinto zalo ezihlukile nezinhlelo zokusebenza ezinhle. Nalu umehluko osemqoka:
1. Ukwakheka kanye nenqubo yokulapha:
Pu Sealant: Kwenziwe nge-polyurethane, yelapha ngokusabela kwamakhemikhali ngomswakama emoyeni. Ngokuvamile kuyanda lapho kufakwa isicelo, ukugcwalisa izikhala ngempumelelo.
I-Silicone Sealant: Kwenziwe kusuka ku-silicone polymers, yelapha ngenqubo ebizwa ngokuthi "ukungathathi hlangothi," okungadingi umswakama. Ihlala ivumelana nezimo ngemuva kokwelapha.
2. Adhesion:
I-PU Sealant: Ngokuvamile inokunamathela okuhle kakhulu ezinhlobonhlobo zama-substrate, kufaka phakathi izinkuni, insimbi, nokhonkolo. Ingabopha kahle ezindaweni ezinama-porous ne-non-porous.
I-Silicone Sealant: Futhi inamathela kahle ezindaweni eziningi, kepha ukunamathela kwayo kungasebenza kangako ezintweni ezithile ezinjengamapulasitiki noma indawo enamafutha.
3. Ukuguquguquka nokunyakaza:
Pu Sealant: Inikeza ukuguquguquka okuhle kepha kungaba yinto encane kakhulu kune-silicone. Ilungele izinhlelo zokusebenza lapho kulindeleke khona ukunyakaza okuthile kodwa kungahle kungaphatheki ukunyakaza okwedlulele kanye ne-silicone.
I-Silicone Sealant: Ivumelana nezimo kakhulu futhi ingahlalisa ukunyakaza okubalulekile ngaphandle kokuqhekeka noma ukulahlekelwa ukunqwabelana, okwenza kube kuhle ngamalunga athola ukwanda nokubuyiselwa.
4. Ukuqina kanye nokumelana nesimo sezulu:
I-PU Sealant: Ngokuvamile imelana nokukhanya kwe-UV nokukhanya kwesimo sezulu, kepha kungahle kukonakala ngokuhamba kwesikhathi uma kuvezwa ukukhanya kwelanga ngaphandle kokuhlobisa.
I-Silicone Sealant: Ukumelana kahle kwe-UV kanye nezakhiwo zesimo sezulu, okwenza zilungele izinhlelo zangaphandle. Ayihlanzeki ngokushesha ngaphansi kokuvezwa kwe-UV.
5. Ukumelana Nezinga lokushisa:
I-PU Sealant: Ingamelana nohla lwamazinga okushisa kodwa ingahle ingasebenzi kahle ngokushisa ngokweqile noma kubanda kakhulu uma kuqhathaniswa ne-silicone.
I-Silicone Sealant: Ngokuvamile inokubekezelelana kwezinga lokushisa okubanzi, okwenza kube lulungele izinhlelo zokushisa okuphezulu.
6. Izicelo:
I-PU Sealant: Isetshenziselwa ukwakhiwa, ukufakwa, kanye nezikhala zokubopha ezindongeni, ophahleni nasezindongeni nasezindaweni ezizungeze amawindi nezicabha.
I-Silicone Sealant: Ivame ukusetshenziswa ezindlini zokugezela, amakhishi, nakwezinye izindawo lapho ukumelana kwamanzi kubalulekile, njengokuvalwa kweka uphawu lokucwila, amashubhu nezimvula.
7. Ukupenda:
I-PU Sealant: Imvamisa ingapendwe ngaphezulu kwake yaphulukiswa, okwenza ilungele izinhlelo zokusebenza lapho ama-arehetics ebalulekile.
I-Silicone Sealant: Ngokuvamile ayinapendi, njengoba upende akunamathele kahle ezindaweni ezisolwandle.
