I-Global - Premier PVA: I-Polymer ekumgangatho ophezulu kwizicelo ezahlukeneyo
IiNdawo eziPhambili zeSicelo
I-PVA isetyenziswa kakhulu kwishishini lempahla. Isebenza njengearhente yokulinganisa imisonto, iphucula amandla ayo kunye nokugudama kwayo ngexesha lokuluka. Oku kunceda ukunciphisa ukuqhekeka kunye nokuphucula umgangatho welaphu. Emva kwenkqubo yokuluka, i-PVA inokususwa ngokulula ngokuhlanjwa, ishiye ilaphu lineempawu zalo zokuqala. Ukongeza, i-PVA isetyenziswa ekuveliseni iingubo zelaphu kunye nezincamathelisi, inika ukunamathela okuhle kunye nokuqina.
Kwishishini lephepha, i-PVA isetyenziswa njengearhente yokulinganisa umphezulu kunye nesixhobo sokubopha. Njengearhente yokulinganisa umphezulu, iphucula ukumelana namanzi, amandla, kunye nokuprintwa kwephepha. Yenza ifilimu encinci, ecacileyo kumphezulu wephepha, ithintela i-inki ukuba ingasasazeki kwaye iphucule ukucaca kwemifanekiso eprintiweyo. Njengesixhobo sokubopha, i-PVA isetyenziswa ekuveliseni amaphepha agqunyiweyo kunye nebhodi yephepha, iphucula ukunamathelana phakathi komaleko wokufaka kunye nesiseko, kwaye iphucula amandla kunye nokuqina kweemveliso zephepha.
I-PVA ikwayinto ebalulekileyo kwishishini lokuncamathelisa. Ineempawu ezibalaseleyo zokuncamathelisa, ngakumbi kwizinto ezinemingxuma ezifana nomthi, iphepha, kunye nempahla. Izincamathelisi ezisekelwe kwi-PVA ziyanyibilika emanzini, kulula ukuzisebenzisa, kwaye zinamandla amahle okunamathela. Zisetyenziswa kakhulu kumashishini okwakha, ifenitshala, kunye nokupakisha ukuze zinamathele kwizinto ezahlukeneyo. Ukongeza, izincamathelisi ze-PVA zinokuguqulwa nezinye izongezo ukuphucula ukumelana kwazo nobushushu, ukumelana namanzi, kunye nezinye iimpawu ukuhlangabezana neemfuno ezithile zokusetyenziswa.
Kwicandelo leengubo zokugquma, i-PVA isetyenziswa njenge-arhente yokwenza ifilimu. Yenza ifilimu ecacileyo, eguquguqukayo, nengangeni manzi kumphezulu wento egqumayo, inika ukhuseleko kumswakama, iikhemikhali, kunye nemitha ye-UV. Iingubo ezisekelwe kwi-PVA zisetyenziswa kakhulu ekukhuseleni umphezulu womthi, isinyithi, kunye neplastiki. Zingasetyenziswa njenge-primer okanye i-intermediate coating ukuphucula ukunamathela kunye nokusebenza kwe-top-coat.
