Okumbi polyurethane foam njengoba ukwahlukanisa

Ngaphambi kokuba uthenge noma iyiphi impahla esinye, umsebenzisi ngamunye ubona amaphutha. Polyurethane foam akuyona ngaphandle. Lokhu kwaziswa, okuthiwa futhi polyurethane, njalo Umakhi namuhla wezwa ulwazi oluningi.

Yini impahla ukukhetha

Uma uke wakucabanga yini ukuthi ukufudumala ekhaya lakho, cishe alalelwa le ndlela njengoba zihlale zifudumele. Mhlawumbe wayeyoba isixazululo esingcono kakhulu, ngoba kanye nemibi ke kunezinzuzo eziningi.

incazelo

Polyurethane foam, okuyinto nemibi kufanele baqaphe ngaphambi kokuqala umsebenzi ukufudumala, uhlobo plastic. Izihloko zayo akheke lezinyosi. Ukwakheka polyurethane kuhlanganisa into gaseous okuyinto eziqukethwe inani kusuka 85 kuya 90%. Yonke isakhiwo siqukethe amaseli encane ukuthi avaleke ngcí komunye nomunye izindonga, lezi cell futhi ugcwale igesi. Inani elisele yesithakazelo iyingxenye okuqinile, okungukuthi izindonga ngokwabo.

Okumbi polyurethane foam njengoba ukwahlukanisa kufanele kubhekwe. Izinhlobonhlobo Foam esetshenziswa namuhla kaningi, okokusebenza ethandwa phakathi abathengi njengoba ukwenza kube silula, kungenziwa ngqo esakhiweni. izingxenye ezimbili liquid ngakho-ke kuyadingeka ukuba uhlanganise ngemva kokuba ungene ukusabela zamakhemikhali. Uma kudingekile ukuba bagcine olinganise izithako, i-polymer iqina is kuhlelwe umqondo okuyinto imelelwa Foam eqina. Uma ezingaphezu kweyodwa ushintsho ukulungiselela ubuchwepheshe, kungenzeka ukuthola polyurethane foams, okuyizinto nezakhi ezihlukene kusuka komunye nomunye. Ezinye zazo yilezi efanelekayo zifudumele of iminyango namafasitela, kuyilapho abanye - ukuze ukwahlukanisa of izakhiwo ngokhonkolo njalo nakakhulu noma isitini. Ngokuphathelene zilwane lwesithathu, basuke kabanzi amapayipi. Ngakho, kuye ngokuthi wacondza izinto, ingatholakala eMhlanganweni ekhishwa polyurethanes okuyinto aqukethe sebuningini amaseli angusayizi ohlukile. Lezi zindonga kungase kudingeke obuhlukahlukene ukujiya kanye namandla.

Ububi main polyurethane foam

Polyurethane foam, ogama kwamaphutha ethulwa ngezansi, ingasetshenziswa ezindaweni eziningi ukwakhiwa. Nokho, ngaphambi kokuthenga kubalulekile ukuthola okuseduzane nge minuses impahla. The main umthelela ongemuhle izenzo kwelanga phezu, okungabangela bafake okusheshayo imikhiqizo. Ukuze uvimbele nokwehliswa kwesithunzi ukushisa ukwahlukanisa, kubalulekile ukuhlinzeka zokuzivikela. Ungasebenzisa usimende, ngidwebe ngopende kanye nokwenza zonke izinhlobo iphaneli abavamile. Lawa izindlela belulekwa abakhi abanolwazi.

I yokuntula Foam ukwahlukanisa njengoba izindonga kuzokuvumela ukuba baqonde yini noma cha ukuyisebenzisa. Isakhiwo avikelayo singawathola ukuvikela ukwahlukanisa kusuka emisebe yama-UV, futhi wenze Foam polyurethane ikhange nakakhulu. Uma ngaphezulu cabangela lokhu negative, kungase kuqashelwe ukuthi ukulondolozwa Foam izakhiwo akudzingi umtfombo ezingaphezu kuka sisebenza ku weatherization ehilela izinto angadingi ngokuvikeleka okwanele. Phakathi kwezinye izinto, hhayi zonke ekhaya-okuyinhloko ziyakwazi ukukhiqiza usimende umsebenzi, kanye qualitatively isicelo Umbala izingoma. Ngenxa yalokho, ebusweni kungenzeka angabi muhle kangako kodwa kunangaphambili nokucwengwa.

negative ezengeziwe

Uma unquma ukhethe Foam polyurethane, okuyinto nemibi kwabanye abathengi bangase babe umxhwele kakhulu, kuhle ukucabangela ukuthi lokhu kokusebenza thermally ngci, okuyinto, lapho zihlatshwa umlilo uqala lungaqhubeka. Lokhu ukungabi ochwepheshe bathi. Naphezu kweqiniso lokuthi Foam uba impahla esha, akusiyo ukwazi ukubhekana umlilo at 100%. Ngokusho Ukwahlukaniswa ukwahlukanisa libhekisela eqenjini combustibility G-2. Lokhu kubonisa ukuthi lapho zihlatshwa ongaphakeme lokushisa ukuthungela ngeke kwenzeke. Ilangabi uyaphuma, inqubo uzoyeka ngokushesha nje lapho yendwangu uzokwazi luphole. Uma kukhona amathuba eqinile kungenzeka umlilo noma ukushisa ukwahlukanisa ezindaweni ezithile, kulesi simo ungawasebenzisi polyurethane foam.

Kungani ungakhethi Foam for nangokuvikela amakhaya

Okumbi nge polyurethane foam ukwahlukanisa Yiqiniso, zikhona. Uma unquma ukwenza ukwahlukanisa, kubalulekile ukucabangela. Uma usebenzisa inqubo engalungile ngokuhamba emsebenzini, kungase zibulale izici ukusebenza ukwakhiwa. Ukuze ugweme lokhu, kufanele ucabangele ezinye izindawo ndaba kuchazwe. Ngakho, igwebu has a ongaphakeme umhwamuko permeability - lokhu kubhekisela zilwane impahla elukhuni. Uma isetshenziswa isakhiwo odongeni, ukucutshungulwa phansi ekamelweni elisophahleni noma ezinye iphaneli ngokuqinisekile kuholele ukuvela umswakama Laphezu engaphakathi isakhiwo. Njengoba imiphumela kungenziwa dampness kanye isikhunta okukhulunywe ngaye, kodwa uma kukhona umnkantsha, izakhi eziveza kuthiwa igoqe unaphakade. Leli phuzu kaningi kuphawulwe ukubuyekeza kwabo abakhi abanolwazi.

Isidingo ukuvikelwa umlilo

Uma unquma ukuthenga polyurethane foam ukukhubazeka Izibuyekezo ikhasimende kudingeka uchaze ngokuningiliziwe. Phela izici ezingezinhle abantu uqaphela kuqala. Ngakho, kufanele ube ukulungele ukuqinisekisa ukuthi ngokuhamba kwesikhathi isakhiwo ilahlekelwa izinga layo ekuvikeleni, kakhulu, bayazibuza nje ukwehla. ukuguga okunjalo Imininingwane akugcini impahla, kodwa futhi okushisa nokuchayeka emisebeni ultraviolet. Kaningi, lapho zifudumele usebenza ngokusebenzisa indlela sputtering, inikeza isivikelo ukuchayeka ukuvula ilangabi. Uma ungafuni ukudala i umlilo ingozi isimo olwengeziwe, kubalulekile ukuthatha ezifanele zokuphepha. Baphinde babe umthombo izindleko ezengeziwe unganelisekile umthengi njalo.

Minus: isidingo cabanga amandla kwesakhiwo

Polyurethane foam, nebubi, ukubuyekezwa okuye ihlaziye kulesi sihloko sinikeza isinqumo efanele isidingo amandla kwesakhiwo. Lokhu kuyiqiniso esimweni lapho umsebenzi ukuphakamisa ohlabayo out ukwahlukanisa esikhaleni phakathi kwezindonga. Ngemva kwalokho, isakhiwo iqala wanda, kamuva kungase kubangele Foam ekubhujisweni. It is hhayi njalo abanikazi izindlu zangasese unekhono lokwenza izibalo lesifanele.

Kungani-ke ngezinye izikhathi abathengi bayenqaba ukusebenzisa Foam

Uma unquma ukusebenzisa le Foam, nebubi, ukubuyekezwa mayelana impahla udinga lihlolwe. Ngakho-ke, engathandeki ukuyisebenzisa ukuze zihlale zifudumele kulesi sakhiwo. Lokhu kungadala displacement iphuzu amazolo odongeni elingaphandle amakamelo ohlangothini. Kulokhu, wogange uqala iqhwa, dampness kwakhiwa kubangela isikhutha ukusabalala ngemuva ukhuni iqala sibole. Kulesi simo, izindonga ahlale emanzi ngisho ehlobo, lapho omubi kuthinta microclimate yamagceke. Ochwepheshe ukweluleka uma ungeke ukwazi ukusebenzisa i-analog izinto, lulwimi ngendlela elukhuni polyurethane foam uhlobo isicelo. Kulesi kuyoba ungqimba ngokwanele kabani ukujiya 30 kwangu.
