PVC Resin
Aia he 4 mau ʻano o ka PVC Resin i hui pū ʻia e ke ʻano polymerization
1. Hoʻokuʻu Papa PVC
2. Emulsion Grade PVC
3. Pvc Polymerised Nui
4. Kopolymer PVC
Hoʻokuʻu Papa PVC
ʻO ke ʻano ākea ākea, ʻo Suspension grade PVC i hana ʻia e ka polymerizing droplets o Vinyl Chloride monomer i hoʻokuʻu ʻia i ka wai.Ke hoʻopau ʻia ka Polymerisation, ua centrifuged ka slurry a hoʻomaloʻo mālie ʻia ka keke PVC e nā ʻōnaehana hoʻomehana kūikawā i ʻole e hoʻokau i ka resin unstabilised i ka wela wela.ʻO ka nui o ka nui o ka resin mai ka 50-250 microns a loaʻa nā porous popcorn e like me nā hale e komo koke i nā Plasticisers.Hiki ke hoʻololi ʻia ke ʻano o nā ʻāpana PVC ma ke koho ʻana i nā mea hoʻomaha kūpono a me ka Polymerisation Catalyst.Hoʻohana nui ʻia nā ʻano porous liʻiliʻi no ka leo kiʻekiʻe Rigid or Unplasticised PVC noi e like me PVC Pipes, Windows, Sidings, Ductings.ʻO nā māka hoʻokuʻu ʻia o ka nui o nā mea ʻeleʻele a me nā hale porous loa e hoʻopili i ka nui o ka Plasticiser e hana ana i kahi maloʻo maloʻo ma nā mahana e like me ka haʻahaʻa e like me 80oC. Hoʻohana ʻia nā ʻano porous i nā noi Plasticised e like me Cable, Footwear, Soft Calendered Sheeting and Films etc.
Emulsion Grade PVC
ʻO Emulsion Polymerised PVC ʻo ia ka Paste Grade Resin a aneane hoʻohana wale ʻia kēia no Plastisols.ʻO ka resin grade paste he PVC nui loa ka nui o nā mea i hana ʻia ma ka hoʻomaloʻo ʻana i kahi Emulsion o PVC i loko o ka wai e like me ka hana ʻana o ka pauka waiū.ʻOi aku ka nui o ka ikehu e hana ai a ʻoi aku ke kumu kūʻai ma mua o ka resin Suspension.Lawe ʻia ka resin grade paste i nā kemika emulsifying a me nā catalysts me ia.No laila ʻoi aku ka maʻemaʻe ma mua o ka Suspension Polymerized a i ʻole Bulk Polymerized PVC.No laila ʻoi aku ka ʻilihune o nā waiwai uila o Paste grade resin plastisols ma mua o ka Suspension Resin Compounds.ʻOi aku ka ʻilihune ma mua o ka Suspension a i ʻole Bulk PVC.Hoʻopili ka resin grade paste i ke ʻano, a ʻaʻole e komo nui i ka Plasticiser i nā wela lumi.Pono nā mahana ma mua o 160-180oC no ka hoʻokuʻu ʻana i ka plasticer i loko o ka Resin i ka wā e ho'ōla ai.Hoʻohana nui ʻia ʻo Paste grade Resin no Cushion Vinyl Floorings o nā ākea ākea.Hoʻopili ʻia nā ʻāpana like ʻole o nā pāpaʻi i hoʻonohonoho pono ʻia ma kahi substrate kūpono (Direct Coating) a i ʻole ma ka Pepa Hoʻokuʻu (Transfer coating).Hoʻohui mau ʻia nā papa i nā umu lōʻihi a ʻōwili ʻia ma hope o ka wehe ʻana o ka pepa.Hiki i ka papahele maikaʻi i ʻōwili ʻia ke loaʻa i kahi papa lole semitransparent paʻakikī ma luna o nā papa i paʻi ʻia a hoʻoulu ʻia e noho ana ma luna o nā ʻaʻahu kumu piha piha e kūkulu i ka mānoanoa.Hiki ke loaʻa nā hopena maikaʻi loa a waiwai a ʻo ia ka mea i hōʻike i ka hopena kiʻekiʻe o Vinyl Flooring.
PVC Polymerised Nui
Hāʻawi ka Bulk Polymerisation i ke ʻano maʻemaʻe o ka resin PVC no ka mea ʻaʻole hoʻohana ʻia nā mea emulsifying a suspending.Hoʻohana nui ʻia lākou i nā noi transparent.Hoʻolako nui ʻia lākou i nā pūʻulu waiwai K haʻahaʻa, ʻoiai ʻo Unplasticised PVC Foils for Blister Packaging a me nā kiʻi ʻoniʻoni Calendered/Extruded Transparent ʻoi aku ka maikaʻi o ka hana ʻana mai nā māka K Value haʻahaʻa.ʻO ka hoʻomaʻemaʻe ʻana i ka ʻenehana resin Suspension ua hoʻopau i ka Bulk PVC i ka wā i hala.
Kopolymer PVC
ʻO Vinyl Chloride ka copolymerized me nā comonomers e like me Vinyl acetate e hāʻawi i kahi ʻano o nā resins me nā waiwai kūʻokoʻa.ʻO PVAc a i ʻole Copolymer o Vinyl Chloride a me Vinyl acetate ka mea nui loa.ʻO ka hoʻoheheʻe maikaʻi ʻana i nā solvents o PVAc ka mea i koho nui no ka Vinyl Printing Inks a me nā cements solvent.Aia kahi noi kūikawā o PVAc i ka papahele papahele a ʻo ia ka resin o ke koho no nā tile Vinyl Asbestos.ʻO ka Resin he mea paʻa maoli ma mua o ka mea nui.Me Copolymer Resin hiki ke hana i nā tile papahele me nā Fillers e like me Asbestos a me Calcium Carbonate helu helu no ka nui o 84% me ka Copolymer a me nā mea hoʻohui hui ʻē aʻe ma lalo o 16%.ʻAʻole hiki ke kiʻekiʻe me ka resin Suspension no ka mea ʻoi aku ka kiʻekiʻe o kona viscosity melt a ʻaʻole hiki ke hoʻokomo a hoʻopili i nā kiʻekiʻe kiʻekiʻe o ka hoʻopiha piha.Pono nā kaʻaahi callendering kūikawā no nā tile asbestos Vinyl.Eia nō naʻe me ka hāʻule ʻana o ka makemake o Asbestos, ua make mālie ia mau huahana.
