Emulsion Stabilizer & Binder
Hiki ke hoʻohana nui ʻia ka PVA ma ke ʻano he colloid pale a mānoanoa no ka polymerization emulsion o vinyl acetate (VAc) a i ʻole VAc/acrylate.loaʻa nā hiʻohiʻona penei: 0adhesiveness maikaʻi loa; hoʻonui ʻia ka hoʻomaka ʻana a me ka helu maloʻo ʻoiai e hoʻohana ʻia me ka mea hoʻopihapiha;kū'ē maikaʻi i kaʻaila;kiʻiʻoniʻoni koʻikoʻi.
I ka hana fiber
ʻElua mau mea nui o ka PVA e hoʻohana ʻia e like me ka vinylon feedstock a me ka sizing agent no ka textile.Ma keʻano he kumu waiwai o ka fiber vinylon, loaʻa nā mea maikaʻi o ke kiʻekiʻe i ka ikaika, ka hoʻoheheʻe ʻana o ka wai, ka pale ʻana i ka abrasion, ka pale ʻana o ka lā, ka pale ʻana a me ke kala keʻokeʻo.Hiki ke wili ʻia me ka pulupulu, ka hulu hipa a me ka viscose fiber a i ʻole i wili wale ʻia me ia iho. Ma ke ʻano he mea nui no ka textile, ʻaʻole ia e corrode a deteriorate me ka hoʻopili maikaʻi ʻana i ka pulupulu, hemp, polyester a me ka fiber viscose.
Ua ʻike ʻia ʻo Pulp & PaperPVA i ka hoʻohana ākea i ka mālama ʻana i ka ʻili pepa no ka mea he maikaʻi loa ka hoʻopili ʻana a me ka hoʻopuehu ʻana a ʻaʻole e pili i ka waiwai o nā mea hoʻopaʻa ʻē aʻe i hoʻohana ʻia i ka hui pū ʻana.ʻO ka maikaʻi o ka PVA me ka hoʻohana ʻana: Ka ikaika o ka ʻili (ka paʻi ʻana) ；Ka ikaika ma ka Z-axis (ka ikaika i loko o ka pepa); Ka pale ʻana i ka pelu; Ke kūpaʻa abrasive; Hoʻomaikaʻi maikaʻi ʻia; Hoʻomaikaʻi ʻia ka glossiness o ka ʻili; Hoʻokiʻekiʻe ʻia ke kūʻē i ka ʻaila a me ka solvent (waiwai pale).
Kiʻiʻoniʻoni
Hiki ke hoʻohana ʻia ka PVA no ka hana ʻana i ka kiʻiʻoniʻoni wai a me ke kiʻi ʻoniʻoni wai. ʻoihana pūʻolo, ʻaʻole wale no ka textile wale nō, akā no nā kemika, nā meaʻai, nā kemika o kēlā me kēia lā, nā mea kanu mahiʻai, nā mea ʻala, a me nā mea ʻē aʻe.
Hoʻopaʻa hoʻopuehu
ʻO ka PVA, ka mea maikaʻi loa i ka pale colloid a ʻoi aku ka maikaʻi o ka hana ʻili, hoʻohana pinepine ʻia e like me ka dispersion stabilizer no ka hoʻokuʻu polymerization o vinyl chloride monomer (VCM).Hiki ke hoʻonui nui ʻia ka hana o ka resin PVC ma ke koho ʻana i kahi māka PVA kūpono me ka pae kūpono o ka polymerization a me ka hydrolysis.
Loaʻa iā mākou ma mua o 1000m2 hale kūʻai no PVA e hōʻoia i ka lako paʻa a me ke kumukūʻai hoʻokūkū mau.
