Choyambira cha polyurethane chofiira (choyambira cha polyurethane chofiira) chimakhala ndi utomoni wokhala ndi hydroxyl, iron oxide red, antidzimbiri pigmented filler, zowonjezera, zosungunulira, ndi zina zotero, ndi utoto wofiira wa polyurethane wachitsulo wokhala ndi zigawo ziwiri wopangidwa ndi polyisocyanate prepolymer.

Kupanga: Palibe chopinga pakugwiritsa ntchito
Mawonekedwe a filimu: Wachibadwa
Momwe zilili mu chidebe: palibe ziphuphu zolimba mutasakaniza ndi kusakaniza, zomwe zili mu mkhalidwe wofanana.
Nthawi youma: kuumitsa pamwamba ≤ 1 ola, kuumitsa kolimba ≤ 24 ola (chiwerengero chokhazikika: GB/T1728-79)
Kukana madzi amchere: palibe ming'alu, palibe matuza, kapena kutayika (standard index: GB/T9274-88)
Kukana asidi: palibe ming'alu, palibe matuza, palibe kutsekeka (Standard index: GB/T9274-88)
Kukana kwa alkali: palibe ming'alu, palibe matuza, palibe kutsekeka (standard index: GB/T9274-88)
Kukana kupindika: 1mm (Chizindikiro chokhazikika: GB/T1731-1993)
Kukana kwa mphamvu: 50cm (chiwerengero chokhazikika: GB/T4893.9-1992)
Kupaka utoto: Kupaka utoto mwachindunji pamwamba pa chitsulo chomwe ubwino wake wochotsa utoto umafika pa giredi ya Sa2.5.
Pambuyo pofananiza: utoto wa polyurethane mica, utoto wa polyurethane, utoto wa acrylic polyurethane top, utoto wa fluorocarbon top.

Kuphulika kwa mchenga pamwamba pa chitsulo kufika pa giredi ya Sa2.5, kukhwima pamwamba pa 30um-75um.
Zipangizo zamagetsi zikutsika kufika pa giredi ya St3.

Makulidwe ofunikira a filimu: 60-80um
Chiwerengero cha majekete omwe akulangizidwa: majekete 2-3
Kutentha kosungirako: -10~40°C
Kutentha kwa zomangamanga: 5 ~ 40°C
Nthawi yoyesera: 6h
Njira yomangira: Kutsuka burashi, kupopera mpweya, kapena kupukuta zingagwiritsidwe ntchito.
Mlingo wongopeka: pafupifupi 115g/m² (kutengera filimu youma ya 35um, kupatula kutayika)
Nthawi yopaka utoto: Kutentha kwa substrate ℃ 5-10 15-20 25-30 Nthawi yochepa h 48 24 12 Nthawi yayitali osapitirira masiku 7.
Kutentha kwa substrate kuyenera kukhala kokwera kuposa mame point opitilira 3 ℃, pamene kutentha kwa substrate kuli kotsika kuposa 5 ℃, filimu ya utoto siikonzedwa, si yoyenera kumangidwa.

Ndi yoyenera kapangidwe ka chitsulo, thanki yamafuta, thanki yamafuta, zida zotsutsana ndi dzimbiri, zida zamagetsi, magalimoto oyendera ngati zokutira zotsutsana ndi dzimbiri.

Mukatsegula mbiya ya gawo A, iyenera kusakanizidwa bwino, kenako tsanulirani gulu B mu gawo A pansi posakaniza malinga ndi zofunikira za gawolo, sakanizani bwino, siyani, phikani kwa mphindi 30, onjezerani kuchuluka koyenera kwa madzi osungunuka ndikukonza kuti kugwirizane ndi kukhuthala kwa kapangidwe kake.
Chosungunula: chosungunula chapadera cha mndandanda wa polyurethane.
Kupopera popanda mpweya: kuchuluka kwa kusungunuka ndi 0-5% (potengera kulemera kwa utoto), kuchuluka kwa nozzle ndi 0.4mm-0.5mm, kuthamanga kwa kupopera ndi 20MPa-25MPa (200kg/cm²-250kg/cm²).
Kupopera mpweya: Kuchuluka kwa kusungunuka ndi 10-15% (potengera kulemera kwa utoto), mulingo wa nozzle ndi 1.5mm-2.0mm, kuthamanga kwa kupopera ndi 0.3MPa-0.4MPa (3kg/cm²-4kg/cm²).
Chophimba cha roller: Kuchuluka kwa dilution ndi 5-10% (potengera kulemera kwa utoto)

Mu nyengo yotentha kwambiri yomanga, kupopera kosavuta kouma, kuti mupewe kupopera kouma, mutha kusintha ndi kupopera kowonda mpaka kupopera kouma kusanaume.
Katunduyu ayenera kugwiritsidwa ntchito ndi akatswiri opaka utoto motsatira malangizo omwe ali pa phukusi la chinthucho kapena bukuli.
Ntchito zonse zokhudzana ndi kugwiritsa ntchito mankhwalawa ziyenera kuchitika motsatira malamulo ndi miyezo yonse yokhudza thanzi, chitetezo ndi chilengedwe.
Ngati mukukayikira ngati mankhwalawa ayenera kugwiritsidwa ntchito, chonde funsani Dipatimenti yathu ya Utumiki Waukadaulo kuti mudziwe zambiri.

Zinthu ziyenera kusungidwa pamalo ozizira komanso opumira mpweya, kupewa kuwala kwa dzuwa mwachindunji, ndikuzipatula ku magwero oyatsa moto, kutali ndi magwero a kutentha m'nyumba yosungiramo zinthu.
Ponyamula katunduyo, ayenera kutetezedwa ku mvula ndi kuwala kwa dzuwa, kupewa kugundana, ndikutsatira malamulo oyenera a dipatimenti yoona za magalimoto.

Malo omangira ayenera kukhala ndi malo abwino opumira mpweya, ndipo openta ayenera kuvala magalasi, magolovesi, zophimba nkhope, ndi zina zotero kuti apewe kukhudzana ndi khungu ndi kupuma mpweya woipa wa utoto.
Kusuta ndi moto ndizoletsedwa kwambiri pamalo omanga.
