Ngophuhliso loshishino lwemibhobho, izinto ezintsha zidweliswe ngokuthe ngcembe kwimarike. Njengemveliso esebenzayo kwishishini lokufakelwa kwe-thermal, umbhobho we-polyurethane ongcwatywe ngokuthe ngqo kwi-thermal insulation ineempawu ezibalaseleyo zokufakelwa kwe-thermal kunye nokusebenza kakuhle komsebenzi. Isetyenziswa kakhulu ngabantu kwaye iye yamkelwa nabasebenzisi. Loluphi uhlobo lombhobho wokugquma we-polyurethane we-thermal osetyenziswa njengombhobho ongcwatywe ngokuthe ngqo? Kuyimfuneko ukwenza umsebenzi omhle wokhuseleko ngexesha lokwakha, kwaye izilumkiso ngexesha lokwakha nazo zibaluleke kakhulu. Ngezantsi, ndingumbhobho we-polyurethane ongcwatywe ngokuthe ngqo kwi-thermal insulation.

Xa uqala ukwakhiwa kombhobho wokugquma we-polyurethane ngokuthe ngqo, ukuthambeka kwegroove kunye nokoma komzantsi wegroove kufuneka kujongwe kuqala, kunye nesanti eshinyeneyo eyi-200mm kufuneka inikezelwe njenge-cushion ngaxeshanye, Iziphelo ezimbini zombhobho wokugquma we-polyurethane ngokuthe ngqo kufuneka zisetyenziswe. Igqunywe yisanti ecolekileyo. Oku kwenzelwa lula ukwakhiwa kunye nokhuseleko lwemibhobho yokufakelwa kwe-polyurethane.

Ikakhulu emva kokuba kufakwe umbhobho wokufakelwa kwe-polyurethane, uvavanyo loxinzelelo lwamanzi kufuneka lwenziwe. Emva kokuphumelela uvavanyo loxinzelelo lwamanzi, unyango olunogwebu lwe-interface lunokwenziwa. Ngexesha le-interface yonyango lwe-foaming, ukucocwa komlomo wombhobho wensimbi yojongano kufuneka kuqinisekiswe. Oku kukuphakamisa ukuphakama. Ukhuseleko lwemibhobho yokufakelwa kwe-polyurethane.

Kamva, xa umbhobho wokufakelwa kwe-polyurethane ungena kwisakhiwo okanye umsele, kufuneka ufakwe kwi-casing eludongeni ukuqinisekisa ukhuseleko lombhobho. Ngokuqinisekileyo, ukufakwa kombhobho wokufakelwa kwe-polyurethane kukulungele, kodwa ezinye izilumkiso zingundoqo ekuphuculeni ukhuseleko lombhobho, ngoko kufuneka ubeke ingqalelo kulolu hlobo lomsebenzi xa ufaka umbhobho wokufakelwa kwe-polyurethane.
