I-Global - Premier PVA: I-Polymer Esezingeni Eliphezulu Yezinhlelo Zokusebenza Ezihlukahlukene
Izinkambu Ezinkulu Zokufaka Isicelo
I-PVA isetshenziswa kabanzi embonini yezindwangu. Isebenza njenge-ejenti yokulinganisa izindwangu, ithuthukisa amandla azo kanye nokushelela kwazo ngesikhathi sokuluka. Lokhu kusiza ukunciphisa ukuphuka nokuthuthukisa ikhwalithi iyonke yendwangu. Ngemva kwenqubo yokuluka, i-PVA ingasuswa kalula ngokuwasha, kushiye indwangu inezakhiwo zayo zokuqala. Ngaphezu kwalokho, i-PVA isetshenziswa ekukhiqizeni izembozo zezindwangu kanye nezinamathiselo, okuhlinzeka ngokunamathela okuhle nokuqina.
Embonini yephepha, i-PVA isetshenziswa njenge-ejenti yokulinganisa ubuso kanye ne-binder. Njenge-ejenti yokulinganisa ubuso, ithuthukisa ukumelana namanzi, amandla, kanye nokunyatheliswa kwephepha. Yakha ifilimu elincane, elibonakalayo ebusweni bephepha, ivimbela uyinki ukuthi ungasabalali futhi ithuthukise ukucaca kwezithombe eziphrintiwe. Njenge-binder, i-PVA isetshenziswa ekukhiqizeni amaphepha amboziwe kanye nebhodi lephepha, ithuthukisa ukunamathelana phakathi kwesendlalelo sokugqoka kanye ne-substrate, futhi ithuthukisa amandla nokuqina kwemikhiqizo yephepha.
I-PVA nayo iyinto ebalulekile embonini yokunamathisela. Inezakhiwo ezinhle kakhulu zokunamathisela, ikakhulukazi ezintweni ezinezimbobo njengokhuni, iphepha, nezindwangu. Izinamathiselo ezisekelwe ku-PVA ziyancibilika emanzini, kulula ukuzisebenzisa, futhi zinamandla amahle okubopha. Zisetshenziswa kabanzi embonini yokwakha, ifenisha, kanye nokupakisha ukubopha izinto ezahlukahlukene. Ngaphezu kwalokho, izinamathiselo ze-PVA zingashintshwa nezinye izithasiselo ukuze kuthuthukiswe ukumelana kwazo nokushisa, ukumelana namanzi, kanye nezinye izakhiwo ukuze kuhlangatshezwane nezidingo ezithile zokusetshenziswa.
Emkhakheni wezingubo zokumboza, i-PVA isetshenziswa njenge-ejenti yokwakha ifilimu. Yakha ifilimu ecacile, eguquguqukayo, futhi engangeni manzi ebusweni bento embozwe, ehlinzeka ngokuvikelwa ekuswakameni, amakhemikhali, kanye nemisebe ye-UV. Izingubo zokumboza ezisekelwe ku-PVA zisetshenziswa kabanzi ekuvikeleni izindawo zokhuni, zensimbi, nezepulasitiki. Zingasetshenziswa futhi njenge-primer noma i-intermediate coating ukuthuthukisa ukunamathela nokusebenza kwe-top - coat.

Ngokufigqiwe
I-Global - Premier PVA yethu itholakala ngamamaki namafomu ahlukene, kufaka phakathi ama-powder, ama-granule, kanye nezixazululo, ukuze kuhlangatshezwane nezidingo ezithile zezimboni ezahlukene. Imaki ngalinye le-PVA linezakhiwo ezithile ezifana ne-viscosity, izinga le-polymerization, kanye nezinga le-alcoholization, ezingenziwa ngokwezifiso ngokwezidingo zamakhasimende. Imikhiqizo yethu ye-PVA ipakishwe ngomswakama - ingangenisi umswakama futhi ipakishwe kahle ukuze kuqinisekiswe ikhwalithi nokuqina kwayo ngesikhathi sokugcina nokuthuthwa. Kungakhathaliseki ukuthi ungumkhiqizi wezindwangu e-Asia, umshini wephepha eYurophu, umkhiqizi we-glue eNyakatho Melika, noma inkampani yokumboza eNingizimu Melika, i-Global - Premier PVA yethu iyi-polymer ethembekile nekhwalithi ephezulu engakusiza ukuthuthukisa ukusebenza kanye nekhwalithi yemikhiqizo yakho.
