Ungazikhetha kanjani izithasiselo ku-polyurethane etholakala emanzini? Kunezinhlobo eziningi zezinsiza ze-polyurethane ezisekelwe emanzini, futhi ububanzi bokusetshenziswa bubanzi, kodwa izindlela zezinsiza zivamile ngokufanayo. 

01

Ukuhambisana kwezithasiselo nemikhiqizo nakho kuyisici sokuqala okufanele sicatshangelwe ekukhetheni izithasiselo. Ngaphansi kwezimo ezivamile, isithasiselo kanye nezinto ezisetshenziswayo kudingeka ukuthi zihambisane (zifane ngesakhiwo) futhi zizinzile (akukho ukukhiqizwa kwezinto ezintsha) ezintweni ezisetshenziswayo, ngaphandle kwalokho kunzima ukudlala indima yesithasiselo.

02

Isithasiselo ezintweni ezingeziwe kumele sigcine ukusebenza kokuqala kwesithasiselo isikhathi eside ngaphandle kokushintsha, futhi ikhono lesithasiselo lokugcina ukusebenza kokuqala endaweni yokusetshenziswa libizwa ngokuthi ukuqina kwesithasiselo. Kunezindlela ezintathu zokulahlekelwa yizakhiwo zazo zokuqala: ukuguquguquka (isisindo sama-molecule), ukukhishwa (ukuncibilika kwemidiya ehlukene), kanye nokufuduka (ukuncibilika kwama-polymer ahlukene). Ngesikhathi esifanayo, isithasiselo kufanele sibe nokumelana namanzi, ukumelana namafutha kanye nokumelana nesinyibilikisi. 

03

Enqubweni yokucubungula izinto, izithasiselo azikwazi ukushintsha ukusebenza kwasekuqaleni futhi ngeke zibe nomthelela omubi ekukhiqizweni nasekucutshungulweni kwemishini nezinto zokwakha.

04

Izithasiselo zokusetshenziswa komkhiqizo, izithasiselo kudingeka zihlangabezane nezidingo ezikhethekile zezinto ezisetshenziswayo, ikakhulukazi ubuthi bezithasiselo.

05

Ukuze uthole imiphumela engcono, ukusetshenziswa kwezithasiselo kuxutshwa kakhulu. Lapho ukhetha inhlanganisela, kunezimo ezimbili: esinye ukusetshenziswa kokuhlanganiswa ukuze kutholakale imiphumela emihle, kanti esinye senzelwe izinjongo ezahlukahlukene, njengokungagcini nje ngokulinganisa kodwa nokususa i-foam, hhayi nje ukwengeza ukukhanya kodwa futhi nokuvimbela ukuguquguquka. Lokhu kufanele kucatshangelwe: ezintweni ezifanayo kuzokhiqiza ukusebenzisana phakathi kwezithasiselo (umphumela ophelele mkhulu kunesamba somphumela wokusetshenziswa kanye), umphumela wokwengeza (umphumela ophelele ulingana nesamba somphumela wokusetshenziswa kanye) kanye nomphumela wokuphikisana (umphumela ophelele ungaphansi kwesamba somphumela wokusetshenziswa kanye), ngakho-ke isikhathi esihle kakhulu sokukhiqiza ukusebenzisana, ukugwema umphumela wokuphikisana.

 

Enqubweni yokukhiqiza i-polyurethane esekwe emanzini ukuze kufakwe uhlobo oluthile lwezithasiselo, kubalulekile ukunaka indima yayo ezigabeni ezahlukene zokugcina, ukwakhiwa, ukusetshenziswa, kanye nokucabangela nokuhlola indima yayo kanye nomthelela wayo esigabeni esilandelayo. 

Isibonelo, uma upende we-polyurethane osekelwe emanzini usebenza ngezinto ezimanzisa nezihlakazayo, udlala indima ethile ekugcineni nasekwakheni, futhi ulungele nombala wefilimu yopende. Ngokuvamile kuba nomphumela oyinhloko, futhi ngesikhathi esifanayo kubangela uchungechunge lwemiphumela emihle ngasikhathi sinye, njengokusetshenziswa kwe-silicon dioxide, kuba nomphumela wokuphela, kanye nokumuncwa kwamanzi, ukulwa nokunamathela ebusweni kanye neminye imiphumela emihle.

Ngaphezu kwalokho, ekusetshenzisweni kwe-ejenti ethile kungaba nomphumela omubi, njengokwengeza i-ejenti yokuhlanzisisa equkethe i-silicon, umphumela wayo wokuhlanzisisa ubalulekile, ungathola umphumela omuhle ophumelelayo, kodwa futhi ukuhlola ukuthi kukhona yini umgodi wokuncibilika, awunamafu, awuthinti ukwakheka kabusha nokunye. Sekukonke, ukusetshenziswa kwezithasiselo, ekuhlaziyeni kokugcina, kuyinqubo esebenzayo, futhi okuwukuphela kwendlela yokuhlola kufanele kube ikhwalithi yemiphumela yesicelo.
