Chikopa chabwino cha PU ndichokwera mtengo kwambiri kuposa chikopa, chokhala ndi mawonekedwe abwino komanso mawonekedwe owala.
01: Zinthu zakuthupi ndi mawonekedwe
Chikopa cha PU chimagwiritsidwa ntchito m'malo mwa chikopa cha PVC, ndipo mtengo wake ndi wapamwamba kuposa chikopa cha PVC. Ponena za kapangidwe ka mankhwala, ili pafupi ndi nsalu yachikopa. Sichifunikira plasticizer kuti chikwaniritse zofewa, chifukwa chake sichikhala cholimba komanso cholimba. Panthawi imodzimodziyo, ili ndi ubwino wa mitundu yolemera ndi mitundu yosiyanasiyana, ndipo mtengo nthawi zambiri umakhala wotsika mtengo kusiyana ndi nsalu zachikopa, choncho amalandiridwa ndi ogula.
Zina ndi PU chikopa. Nthawi zambiri, mbali yakumbuyo ya chikopa cha PU ndi gawo lachiwiri lachikopa chaiwisi, chomwe chimakutidwa ndi utomoni wa PU, motero amatchedwanso chikopa cha ng'ombe. Mtengo wake ndi wotchipa ndipo kuchuluka kwake komwe kumagwiritsidwa ntchito ndikokwera. Ndi kusintha kwaukadaulo, amapangidwanso kukhala mitundu yamitundu yosiyanasiyana, monga yochokera kunja yamitundu iwiri yachikopa yaiwisi. Chifukwa cha luso lake lapadera, khalidwe lokhazikika, mitundu yatsopano ndi zizindikiro zina, ndi zikopa zamakono zamakono, ndipo mtengo wake ndi kalasi ndizocheperapo kuposa chikopa choyamba. PU chikopa ndi chikopa chenicheni ali ndi makhalidwe awo. Maonekedwe a chikopa cha PU ndi chokongola komanso chosavuta kuchisamalira. Mtengo wake ndi wotsika, koma sunavale komanso wosavuta kuswa; Chikopa chenicheni ndi chokwera mtengo, chovuta kuchisamalira, koma cholimba.
(1) Mphamvu zapamwamba, zowonda komanso zotanuka, zofewa komanso zosalala, kupuma kwabwino komanso kuloleza madzi, komanso kusalowa madzi.
(2) Pa kutentha kochepa, imakhalabe ndi mphamvu zokhazikika komanso mphamvu zosunthika, kukana kukalamba bwino komanso kukana kwa hydrolysis.
(3) Sichimamva kuvala, ndipo maonekedwe ake ndi machitidwe ake ndi ofanana ndi a zikopa zachilengedwe. Ndiosavuta kuchapa, kuwononga ndi kusoka.
(4) Pamwambapo ndi yosalala komanso yophatikizika, yomwe imatha kugwiritsidwa ntchito popangira mankhwala osiyanasiyana komanso utoto. Zosiyanasiyana zimakhala zosiyanasiyana ndipo mtengo wake ndi wochepa.
(5) Kuyamwidwa ndi madzi sikophweka kukulitsa ndi kupunduka, ndipo ndikochezeka ndi chilengedwe.
