Mu makampani opanga chakudya, lamba wonyamula katundu si gawo lofunika kwambiri pa kayendedwe ka zinthu zokha, komanso ndi chinsinsi chotsimikizira kuti chakudya chili bwino komanso kuti zinthu zikuyenda bwino. Popeza pali zinthu zambiri zomwe zimagwiritsidwa ntchito popanga zinthu, PU (polyurethane) ndi PVC (polyvinyl chloride) mosakayikira ndi zinthu ziwiri zomwe zimagwiritsidwa ntchito kwambiri. Ngakhale kuti mawonekedwe a zinthu ziwirizi ndi ofanana, kusiyana kwa magwiridwe antchito n'kofunika kwambiri. M'nkhaniyi, tikambirana kusiyana kwakukulu pakati pa zinthu ziwirizi kuchokera ku makhalidwe a zinthuzo, momwe zimagwiritsidwira ntchito, momwe zimagwiritsidwira ntchito bwino komanso momwe zimagwirira ntchito, kuti tikuthandizeni kupanga chisankho chanzeru.

 Masewera a Chitetezo ndi Kuchita Bwino

 

Malamba onyamula katundu a PU: "muyezo wagolide" wa chitetezo cha chakudya.

Satifiketi ya chakudya: Malamba onyamula katundu a PUAmapangidwa ndi zinthu zopangidwa ndi polyurethane, zomwe zikugwirizana ndi miyezo yapadziko lonse ya chitetezo cha chakudya monga FDA, sizili ndi poizoni komanso zopanda fungo, ndipo zimatha kulumikizidwa mwachindunji ndi chakudya, makamaka choyenera kuphika buledi, makeke, zinthu za nyama ndi zina zoyera kwambiri.

Mafuta ndi Zosatha Kuvala: Zipangizo za PU zili ndi kukana mafuta bwino kwambiri, zomwe zimatha kukana kuwonongeka kwa mafuta, mafuta a nyama ndi mafuta a makina, ndipo nthawi yomweyo, zimakhala ndi kukana kwakukulu kwa kuwonongeka, komwe kuli koyenera kunyamula buledi, mtanda ndi zinthu zina zosavuta kumamatira.

Kuletsa kudula ndi kukana kuuma: Kulimba kwambiri (92 Kulimba kwa Shore) ndi kusakanikirana kochepa, kotero kuti imatha kupirira kudula kwa mpeni komanso kuwononga mosavuta, komanso magwiridwe antchito oletsa kumatira ndi abwino kwambiri, kuti tipewe zotsalira za chakudya.

Kukana kutentha kwambiri: kutentha kwa ntchito kumatha kufika -20℃ mpaka 80℃, kusinthasintha ku malo ovuta kwambiri monga kusungirako kozizira ndi kuphika.

 

Lamba wonyamulira wa PVC: chisankho chotsika mtengo, koma chiyenera kugwiritsidwa ntchito mosamala

Yotsika mtengo komanso yothandiza: Lamba wonyamulira wa PVCYapangidwa ndi nsalu ya polyester fiber ndipo yokutidwa ndi PVC glue layer, mtengo wake ndi 60%-70% yokha ya PU conveyor lamba, yomwe ndi yoyenera mabizinesi omwe ali ndi bajeti yochepa.

Kukana kwa asidi ndi alkali ndi katundu wopepuka:Ili ndi mphamvu zina zotsutsana ndi asidi wofooka komanso malo okhala ndi alkali ndipo ndi yoyenera kunyamula zipatso ndi ndiwo zamasamba mopepuka, ndi zina zotero. Komabe, ili ndi mphamvu zochepa zotsutsana ndi mafuta, ndipo kukhudzana kwa mafuta ndi mafuta kungayambitse kufalikira kwa rabara ndikugwa mosavuta.

Kuchepetsa kutentha: Kutentha kwa ntchito kumayambira pa -10℃ mpaka 80℃, ndipo n'kosavuta kufooka ndikufupikitsa nthawi yogwira ntchito pansi pa kutentha kwambiri.

Kuopsa kwa chitetezo cha chakudya:enaMalamba onyamulira a PVCZingakhale ndi zinthu zopukutira pulasitiki, kukhudzana mwachindunji ndi chakudya pali zoopsa zina, muyenera kusankha zinthu za PVC zapamwamba zomwe zavomerezedwa ndi FDA.
