Isinyathelo Ngesinyathelo Umhlahlandlela Wokusebenzisa Igwebu Le-PU Elinwebekayo

Ukusebenzisa igwebu le-PU elinwebekayo kungaba yindlela enhle yokuvala izikhala, ukuvala izindawo, nokugcwalisa izikhala. Kodwa-ke, kubalulekile ukulandela izinyathelo ezifanele zokuqinisekisa ukuthi igwebu lisebenza ngempumelelo nangempumelelo. Kulo mhlahlandlela wesinyathelo nesinyathelo, sizokuhamba ngenqubo yokufaka igwebu le-PU elinwebekayo elinezincazelo ezinemininingwane namathiphu ukukusiza ukuzuza imiphumela engcono kakhulu ngangokunokwenzeka.

Ukulungiselela

Ngaphambi kokuthi uqale ukusebenzisa igwebu le-PU elinwebekayo, kubalulekile ukulungisa indawo kahle. Okokuqala, qiniseka ukuthi uhlanza indawo lapho uzobe usebenzisa khona igwebu. Susa noma yikuphi ukungcola, uthuli, amafutha, noma imfucumfucu njengoba lokhu kungase kuthinte ukunamathela kwegwebu. Okulandelayo, hlola amazinga okushisa nomswakama endaweni. Izinga lokushisa elifanele lokusebenzisa i-PU Foam elinwebekayo liphakathi kuka-60-80°F (15-27°C) nomswakama ongaphansi kuka-60%. Qiniseka ukuthi ugqoka izinto zokuzivikela ezifanele, okuhlanganisa amagilavu, izibuko, kanye nemaski ukuze uzivikele kumakhemikhali ayigwebu.

Inqubo Yohlelo Lokusebenza

Inqubo yokufaka isicelo segwebu le-PU elinwebekayo ibandakanya izinyathelo ezimbalwa zokuqinisekisa ukwanda nokwelashwa okufanele. Qala ngokunyakazisa i-canister ngamandla imizuzwana engaba ngu-30 ukuze uhlanganise izingxenye kahle. Namathisela utshani besicelo ku-nozzle bese uhlola ukugeleza kwegwebu endaweni ehlukile ngaphambi kokuyisebenzisa endaweni oyifunayo. Bamba i-canister ulibhekise phansi bese uqala ukusebenzisa igwebu ngokunyakaza okuqhubekayo, ususa i-canister kude nendawo njengoba igwebu likhula. Qinisekisa ukuthi ungagcwalisi izikhala noma ama-voids, njengoba igwebu lizokhula.

Isikhathi sokuphumula

Ngemuva kokufaka igwebu le-PU elinwebekayo, kubalulekile ukuyivumela ukuthi yelapheke kahle. Isikhathi sokuphulukisa sizohluka kuye ngezinga lokushisa, umswakama, nokuqina kongqimba lwegwebu. Ngokuvamile, igwebu le-PU elinwebekayo lizoqala ukungathinteki phakathi kwemizuzu eyi-10-15 futhi lelaphe ngokugcwele phakathi kwamahora angu-6-8. Kubalulekile ukugwema ukuthinta noma ukuphazamisa igwebu ngesikhathi senqubo yokwelapha ukuze uqinisekise ukwelashwa okuphelele nokufana. Uma igwebu selipholile, ungakwazi ukusika noma yiliphi igwebu elidlulele ngommese womsebenzi noma isaha ukuze ufinyelele isiphetho esibushelelezi.

Ukubeka uphawu kanye nokuvikela

Igwebu le-PU elinwebekayo lihle kakhulu ekuvaleni izikhala, imifantu, nama-voids ukuvimbela ukuvuza komoya nokungena komswakama. Uma usebenzisa igwebu ukuze uvale izikhala, qiniseka ukuthi ugcwalisa yonke indawo ukuze udale uphawu olungangenisi umoya. Ngezinjongo zokufaka i-insulating, sebenzisa igwebu ngezendlalelo ukuze ufinyelele inani elingu-R elifiselekayo lokufakwa kwe-thermal. Igwebu le-PU elinwebekayo lingasetshenziswa futhi ukugcwalisa imigodi nezikhala ezizungeze amafasitela, iminyango, amapayipi, nezitolo zikagesi ukuze kuthuthukiswe ukusebenza kahle kwamandla kanye nokunethezeka kwangaphakathi.

Hlanza Nokuphepha

Ngemuva kokuqeda ukusetshenziswa kwegwebu le-PU elinwebekayo, kubalulekile ukuhlanza noma yiliphi igwebu elidlulele namathuluzi ngendlela efanele. Sebenzisa isicoci segwebu noma i-solvent ukuze ususe igwebu elingalapheki endaweni, esikhunjeni, namathuluzi. Gwema ukusebenzisa i-acetone noma amanye amakhemikhali anokhahlo ngoba angalimaza indawo engaphezulu. Lahla amathini egwebu angenalutho ngokwemithetho yendawo yemfucuza eyingozi. Khumbula ukugcina amathini egwebu angasetshenzisiwe endaweni epholile, neyomile kude nemithombo yokushisa nalapho izingane nezilwane ezifuywayo zingakwazi ukufinyelela kuzo.

Sengiphetha, ukusebenzisa igwebu le-PU elinwebekayo kungaba indlela elula nephumelelayo yokuvala, ukuvala indawo, nokugcwalisa izikhala ezizungeze ikhaya lakho noma indawo yokusebenza. Ngokulandela umhlahlandlela wesinyathelo ngesinyathelo ovezwe ngenhla futhi uthathe izinyathelo zokuphepha ezifanele, ungafinyelela imiphumela yobungcweti ngegwebu le-PU elinwebekayo. Noma ngabe ungumthandi we-DIY noma usonkontileka ochwepheshe, igwebu le-PU elinwebekayo liwumkhiqizo oguquguqukayo ongakusiza uthuthukise ukusebenza kahle kwamandla, ukunethezeka kwangaphakathi, nobuqotho besakhiwo.
