Global - I-PVA Lephakeme: I-Polymer Lesezingeni Leliphakeme Yekusebentisa Letehlukahlukene
Tindzawo Letinkhulu Tesicelo
I-PVA isetjentiswa kakhulu embonini yetintfo tekugcoka. Isebenta njenge sizing agent yetintsambo, kwenta ncono emandla ato kanye nekushelela ngesikhatsi sekuluka. Loku kusita kunciphisa kwephuka kanye nekutfutfukisa lizinga leliphelele lendvwangu. Ngemuva kwenchubo yekuluka, iPVA ingasuswa kalula ngekugeza, kushiya lendvwangu ngetimphahla tayo tekucala. Ngekwengeta, iPVA isetjentiswa ekukhiciteni tindvwangu tekugcoka kanye nekunamatsela, kuniketa kunamatsela lokuhle kanye nekucina.
Emkhakheni wemaphepha, iPVA isetjentiswa njenge-ejenti yekulinganisa ebusweni kanye ne-binder. Njenge-ejenti yekulinganisa indzawo, yenta ncono kumelana nemanti, emandla, kanye nekuphrinteka kweliphepha. Yakha ifilimu lencane, lebonakalako ephepheni, ivimbela inki kutsi ingasakateki futsi yente ncono kucaca kwetitfombe letishicilelwe. Njengesibopho, iPVA isetjentiswa ekukhiciteni emaphepha lagcotshiwe kanye nemaphepha, kwenta ncono kunamatsela emkhatsini welucwencwe lwekugcobisa kanye ne substrate, kanye nekutfutfukisa emandla onkhe kanye nekucina kwemikhicito yemaphepha.
I-PVA iphindze ibe yintfo lebalulekile embonini yekunamatsela. Inetintfo letinhle kakhulu tekunamatsela, ikakhulukati tintfo letinema-porous letifana netigodvo, emaphepha, kanye netindvwangu. PVA - ema adhesives lasekelwe emanti - ancibilika, kulula kusebentisa, futsi anemandla lamahle ekubopha. Tisetjentiswa kakhulu ekwakhiweni, ifenisha, kanye netimboni tekupakisha tekubopha tintfo letehlukahlukene. Ngekwengeta, ema PVA adhesives angashintjwa naletinye tintfo letingetiwe kwentela kwenta ncono kumela kwawo kushisa, kumela emanti, kanye naletinye tintfo kwentela kuhlangabetana netidzingo letitsite tekusebentisa.
Emkhakheni wekugcobisa, i-PVA isetjentiswa njengefilimu - i-ejenti leyakha. Yakha ifilimu lebonakalako, legucugucukako, futsi lemelana nemanti etulu kwentfo lefakwe, iniketa kuvikeleka kumswakama, emakhemikhali, kanye nemisebe ye UV. PVA - based coatings kusetjentiswa kakhulu ekuvikeleni tigodvo, insimbi, kanye netindzawo tepulasitiki. Tingaphindze tisetjentiswe njenge primer noma kugcoka lokusemkhatsini kwenta ncono kunamatsela kanye nekusebenta kwe top - coat.

Ngalokufishane
I-PVA yetfu yemhlaba wonkhe - Premier iyatfolakala ngemabanga lehlukene kanye netindlela, kufaka ekhatsi emaphuphu, ema-granules, kanye netisombululo, kuhlangabetana netidzingo letitsite tetimboni letehlukene. Libanga ngalinye le PVA linetintfo letitsite letifana ne viscosity, lizinga le polymerization, kanye nelizinga le alcoholysis, lelingalungiswa ngekuya kwetidzingo temakhasimende. Imikhicito yetfu ye PVA ipakishwa ngemswakama - bufakazi kanye nemoya - emaphakethe lacinile kwentela kucinisekisa lizinga layo kanye nekusimama ngesikhatsi sekugcina kanye nekutfutsa. Noma ngabe ungumkhiciti wetindvwangu e-Asia, umshini wekugaya emaphepha eYurophu, umkhiciti wekunamatsela eNyakatfo Melika, noma inkampani yekugcobisa eNingizimu Melika, i-PVA yetfu ye-Global - Premier yi-polymer letsembekile nalesezingeni leliphakeme lengakusita kutsi utfutfukise kusebenta kanye nelizinga lemikhicito yakho.
