Kodi mungasankhe bwanji zowonjezera mu polyurethane yoyendetsedwa ndi madzi? Pali mitundu yambiri ya zinthu zothandizira polyurethane zochokera m'madzi, ndipo mitundu yosiyanasiyana ya zinthu zomwe zimagwiritsidwa ntchito ndi yotakata, koma njira zothandizira ndizokhazikika. 

01

Kugwirizana kwa zowonjezera ndi zinthu ndi chinthu choyamba chomwe chiyenera kuganiziridwa posankha zowonjezera. Muzochitika zachizolowezi, chothandizira ndi zinthuzo ziyenera kukhala zogwirizana (zofanana mu kapangidwe kake) komanso zokhazikika (zopanda kupanga zinthu zatsopano) muzinthuzo, apo ayi zimakhala zovuta kuchita gawo la chothandizira.

02

Chowonjezera mu zowonjezera chiyenera kusunga magwiridwe antchito oyamba a chowonjezera kwa nthawi yayitali popanda kusintha, ndipo kuthekera kwa chowonjezera kusunga magwiridwe antchito oyamba mu malo ogwiritsira ntchito kumatchedwa kulimba kwa chowonjezera. Pali njira zitatu zothandizira kutaya mawonekedwe awo oyamba: kusinthasintha (kulemera kwa mamolekyulu), kutulutsa (kusungunuka kwa zinthu zosiyanasiyana), ndi kusamuka (kusungunuka kwa ma polima osiyanasiyana). Nthawi yomweyo, chowonjezeracho chiyenera kukhala ndi kukana madzi, kukana mafuta ndi kukana zosungunulira. 

03

Mu ndondomeko yokonza zinthu, zowonjezera sizingasinthe momwe zinthu zinalili poyamba ndipo sizingawononge kupanga ndi kukonza makina ndi zinthu zomangira.

04

Zowonjezera kuti zinthu zigwirizane ndi momwe zinthuzo zimagwiritsidwira ntchito, zowonjezera ziyenera kukwaniritsa zofunikira zapadera za zinthuzo pakugwiritsa ntchito, makamaka poizoni wa zowonjezerazo.

05

Kuti mupeze zotsatira zabwino, kugwiritsa ntchito zowonjezera nthawi zambiri kumakhala kosakanikirana. Posankha kuphatikiza, pali zochitika ziwiri: chimodzi ndi kugwiritsa ntchito kuphatikiza kuti mupeze zotsatira zabwino, ndipo china ndi cha zolinga zosiyanasiyana, monga osati kungolinganiza komanso kuchotsa poizoni, osati kungowonjezera kuwala komanso antistatic. Izi ndi zofunika kuganizira: mu chinthu chomwecho chidzapanga mgwirizano pakati pa zowonjezera (zotsatira zonse ndi zazikulu kuposa kuchuluka kwa zotsatira za kugwiritsidwa ntchito kamodzi), zotsatira zowonjezera (zotsatira zonse ndi zofanana ndi kuchuluka kwa zotsatira za kugwiritsidwa ntchito kamodzi) ndi zotsatira zotsutsana (zotsatira zonse ndi zochepa kuposa kuchuluka kwa zotsatira za kugwiritsidwa ntchito kamodzi), kotero nthawi yabwino yopangira mgwirizano, kuti mupewe zotsatira zotsutsana.

 

Pakupanga polyurethane yochokera m'madzi kuti muwonjezere mtundu wina wa zowonjezera, ndikofunikira kulabadira ntchito yake m'magawo osiyanasiyana osungira, kumanga, kugwiritsa ntchito, ndikuganizira ndikuwunika ntchito yake ndi momwe imakhudzira mu gawo lotsatira. 

Mwachitsanzo, pamene utoto wa polyurethane wochokera m'madzi umagwiritsidwa ntchito ndi zinthu zonyowetsa ndi kufalitsa, umagwira ntchito inayake pakusunga ndi kumanga, ndipo umakhalanso wabwino pa mtundu wa utoto. Nthawi zambiri pamakhala zotsatirapo zazikulu, ndipo nthawi yomweyo zimayambitsa zotsatira zabwino zingapo nthawi imodzi, monga kugwiritsa ntchito silicon dioxide, pamakhala zotsatira zotha, komanso kuyamwa kwa madzi, kukana kumatira pamwamba ndi zotsatira zina zabwino.

Kuphatikiza apo, pakugwiritsa ntchito chinthu china, chingakhale ndi zotsatirapo zoipa, monga kuwonjezera chinthu chochotsera poizoni chokhala ndi silicon, zotsatira zake zochotsera poizoni zimakhala zazikulu, zitha kukhala ndi zotsatira zabwino, komanso kuwunika ngati pali dzenje lochepa, silili ndi mitambo, silikhudza kubwezeretsanso ndi zina zotero. Pomaliza, kugwiritsa ntchito zowonjezera ndi njira yothandiza, ndipo chofunikira chokhacho chowunikira chiyenera kukhala mtundu wa zotsatira za kugwiritsa ntchito.
