1. Xana Rigid PVC sheet i yini?
Vito leri heleleke ra PVC rigid sheet i polyvinyl chloride rigid sheet. Rigid PVC sheet i polymer material leyi endliweke hi vinyl chloride tani hi raw material, laha ku engeteriweke ti stabilizers, lubricants na fillers. Yina super high antioxidant, acid yo tiya xikan’we na reduction resistance, matimba yale henhla, kutshamiseka kahle swinene xikan’we naku nga pfurhi, naswona yinga lwisana na corrosion leyi vangiwaka hiku cinca ka maxelo. Maphepha yo tiya ya PVC lawa ya tolovelekeke ya katsa maphepha ya PVC lawa ya vonakaka, maphepha ya PVC yo basa, maphepha ya PVC ya ntima, maphepha ya PVC ya mihlovo, maphepha ya PVC ya grey, na swin’wana.
2. Hi wihi vuyelo bya Rigid PVC sheet?
Ti PVC sheets leti tiyeke tina swipfuno swotala swofana naku lwisana na corrosion, kunga pfurhi, insulation, xikan’we naku lwisana na oxidation. Ku engetela kwalano, tinga tlhela ti lulamisiwa naswona tina ntsengo wale hansi wa vuhumelerisi. Hikwalaho ka matirhiselo ya tona yohambana hambana xikan’we na minxavo leyi ringaneleke, minkarhi hinkwayo ya teka xiphemu xa makete wa ti plastic sheet. Sweswi, thekinoloji ya tiko ra hina yo antswisiwa na ku dizayina maphepha ya PVC yi fikelele xiyimo xa le henhla xa matiko ya misava.
3. Xana ku tirhisiwa kwihi ka PVC sheet?
Maphepha ya PVC ya cinca cinca swinene, naswona kuna tinxaka tohambana hambana ta maphepha ya PVC, kufana na maphepha ya PVC lawa yanga erivaleni, maphepha ya PVC lawa yanga frosted, maphepha ya PVC ya rihlaza, ti rolls ta maphepha ya PVC, na swin’wana hikokwalaho ka matirhelo ya kahle ya yona yo lulamisa, ntsengo wale hansi wa vumaki, ku lwisana na corrosion xikan’we naku pfaleriwa. Maphepha ya PVC ya tirhisiwa ngopfu naswona ya tirhisiwa ngopfu ku endla: Swifunengeto swo boha swa PVC, makhadi ya PVC, tifilimi to tiya ta PVC, maphepha yo tiya ya PVC, na swin’wana.
4. Hi xihi xiphiqo xa PVC sheet?
PVC sheet na yona i pulasitiki leyi tirhisiwaka ngopfu. I resin leyi vumbiweke hi polyvinyl chloride resin, plasticizer na antioxidant. A hi chefu hi yoxe. Kambe switirhisiwa leswikulu leswi pfunetaka swofana na ti plasticizers nati antioxidants swina chefu. Ti plasticizers eka tipulasitiki ta siku na siku ta PVC sheet ngopfu ngopfu ti tirhisa dibutyl terephthalate na dioctyl phthalate. Tikhemikhali leti ti ni chefu. Antioxidant lead stearate leyi tirhisiwaka eka PVC na yona yina chefu. Ti PVC sheets letingana ti lead salt antioxidants tita precipitate lead loko ti hlangana na ti solvents tofana na ethanol na ether. Maphepha ya PVC lawa yanga na lead ya tirhisiwa eka ku paka swakudya. Loko va hlangana na tinhonga ta nhlama leti oxiweke, tikhekhe leti oxiweke, tihlampfi leti oxiweke, switirhisiwa swa nyama leswi swekiweke, ti pastry na swakudya swo olova, na swin’wana, ti molecules ta lead tita hangalaka eka mafurha. Hikokwalaho, ti plastic bags ta PVC sheet tinga tirhisiwi ku khoma swakudya, ngopfu ngopfu swakudya leswingana mafurha. Ku engetela kwalano, switirhisiwa swa tipulasitiki ta polyvinyl chloride swita bola hakatsongotsongo gasi ya hydrogen chloride eka mahiselo yale henhla, kufana na kwalomu ka 50°C, leswinga na khombo eka miri wa munhu.
