Hoʻokaʻawale ʻia nā resins PVC e kā lākou K-Value, kahi hōʻailona o ke kaumaha molecular a me ke degere o ka polymerization.
• ʻO K70-75 nā resins waiwai K kiʻekiʻe e hāʻawi i nā waiwai mechanical maikaʻi loa akā ʻoi aku ka paʻakikī o ka hana.Pono lākou i ka plasticizer no ka palupalu like.ʻO nā insulations kelepona hana kiʻekiʻe i ka resin Suspension a me nā uhi paʻakikī no nā kāʻei Conveyor, Industrial Flooring a me nā noi hopena kiʻekiʻe like i ka papa Paste kekahi mau noi kaulana.ʻO ia ke kumu kūʻai nui loa.
• ʻO K65-68 he resin K waiwai nui i kaulana loa.Loaʻa iā lākou kahi kaulike maikaʻi o nā waiwai Mechanical a me ka processibility.Hana ʻia ʻo UPVC (Unplasticised or Rigid PVC) mai nā māka liʻiliʻi liʻiliʻi a ʻoi aku ka maikaʻi o nā noi Plasticised mai nā māka ʻoi aku ka porous.Nui nā koho papa e like me ka mālama ʻana i ka hapa nui o nā noi PVC.Ma muli o ka nui o ka nui o kēia ʻohana PVC resins ke kumu kūʻai haʻahaʻa loa.
• ʻO K58-60 nā pae K-waiwai haʻahaʻa.ʻOi aku ka haʻahaʻa o nā waiwai mīkini, akā ʻoi aku ka maʻalahi o ka hana ʻana.Nui ka paʻakikī o ka hoʻoponopono ʻana i nā noi e like me ka injection molding, blow molding a me Clear Calendered packaging film i hana ʻia mai nā pae waiwai K haʻahaʻa.ʻOi aku ka nui o nā kumukūʻai ma mua o ka Medium K Value Resins.
• K50-55 nā resins kūikawā i hana ʻia no kekahi mau noi koi.ʻO nā mea hoihoi he Battery Separator Resins a me Blending resins i hoʻohana pū ʻia me Paste Grade resin e hōʻemi i nā kumukūʻai.ʻOi aku ka maʻalahi o ka hana ʻana.
ʻOiai ʻo PVC he 56% Chlorine, ʻo ia kekahi o nā Polymers liʻiliʻi e hoʻopau iā ia iho, ʻoiai ʻo Chlorine kahi mea paʻa ahi ikaika.
He aha ka waiwai K ma PVC?
K - ʻO ka waiwai ke ana o ka degere o ka polymerization a i ʻole ka helu o nā monomer i loko o ke kaulahao PVC a i ʻole ke kaumaha molekala.No ka mea ʻoi aku ka nui o ka % o PVC i nā kiʻiʻoniʻoni a me nā pepa, he mea koʻikoʻi kona waiwai K.K - Loaʻa ka waiwai i nā waiwai o ka resin PVC, ka hana ʻana a me nā waiwai o ka huahana.7.
He aha ka k67 PVC resin?
ʻO PVC Resin Virgin (K -67), i hoʻopau pinepine ʻia ʻo PVC, ʻo ia ke kolu o ka polymer i hana nui ʻia, ma hope o ka polyethylene a me ka polypropylene.Hoʻohana ʻia ke ʻano paʻa o PVC i ke kūkulu ʻana no ka paipu a me nā noi profile e like me nā puka a me nā puka makani.
He aha ka PVC resin?
ʻO ka Poly Vinyl Chloride Resin a i ʻole PVC Resin e like me ka mea i kapa ʻia, he thermoplastic Resin hiki ke hoʻomaʻamaʻa ʻia i ka hoʻomehana ʻana.ʻO kahi huaʻōlelo maʻamau no kēia polymer waiwai ʻo Vinyl.Loaʻa pinepine ʻia ma ke ʻano o ka pauka, kūpaʻa nui nā granule PVC i ka oxidization a me ka degradation ma muli o ka hopena o ka lewa.
He aha ka waiwai K?
He pōkole wale ka K-value no ka thermal conductivity.ʻO ka hoʻoheheʻe wela, n: ka manawa o ka holo ʻana o ka wela ma waena o kahi ʻāpana o kahi mea like like i hoʻoulu ʻia e kahi ʻanuʻu wela ma kahi ʻaoʻao e kū pono ana i kēlā ʻāpana.
Pehea ʻoe e helu ai i ka waiwai k?
Hiki iā lākou ke helu ʻia ma ke ʻano he 1 / (ka huina o nā kū'ē o nā ʻāpana like ʻole o ka mea (kona R-waiwai) + ke kū'ē ʻana o ka ʻili o loko a me waho o ka mea.
Aia nā māka like ʻole o PVC?
ʻElua ʻano maʻamau o ka paipu PVC - ka papahana 40 PVC a me ka papa hana 80 PVC.Hōʻike 40 He keʻokeʻo maʻamau ka PVC i ka waihoʻoluʻu a ʻo ka papa 80 he ʻeleʻele hina hina (hiki ke loaʻa iā lākou i nā kala ʻē aʻe).ʻO kā lākou ʻokoʻa koʻikoʻi, ʻoiai, aia i kā lākou hoʻolālā.Hoʻolālā ʻia ka paipu 80 me ka pā mānoanoa.
He aha ka UPVC e hoʻohana ai?
ʻO UPVC, i kapa ʻia ʻo Unplasticized Polyvinyl Chloride, he mea hale mālama haʻahaʻa i hoʻohana ʻia ma ke ʻano he pani no ka lāʻau pena, ʻo ka hapa nui no nā papa pukaaniani a me nā sills i ka wā e hoʻokomo ai i nā aniani ʻelua i nā hale hou, a i ʻole e pani i nā pukaaniani aniani kahiko.
Pehea ʻoe e helu ai i ka waiwai k?
No ka helu ʻana i ka K-Waiwai o ka insulation, e puʻunaue wale i ka mānoanoa (i nā ʻīniha) me ka R-Value.
He aha ka waiwai K?
He pōkole wale ka K-value no ka thermal conductivity.ʻO ka hoʻoheheʻe wela, n: ka manawa o ka holo ʻana o ka wela ma waena o kahi ʻāpana o kahi mea like like i hoʻoulu ʻia e kahi ʻanuʻu wela ma kahi ʻaoʻao e kū pono ana i kēlā ʻāpana.ʻAʻole paʻakikī loa kēia wehewehe.
He aha ka K i loko o ka viscosity?
ʻO ka waiwai K (viscosity), he ʻano hoʻohālikelike pili pili i ka viscosity intrinsic, i wehewehe pinepine ʻia ma nā ʻano ʻokoʻa iki i nā ʻoihana like ʻole e hōʻike i ka viscosity ma muli o ka manaʻo o ka nui molekiko helu o nā mea polymeric i hoʻohana ʻia no PVC.
He aha ke ʻano kemika no PVC?
ʻO PVC ka Polyvinyl Chloride.He palaki kēia i loaʻa ke ʻano kemika penei: CH2=CHCl (e nānā i ke kiʻi ma ka ʻākau).Ua uhi ʻia ka plastik i ka huhū nui o nā huahana polymerization synthetic a semi-synthetic paha (ʻo ia hoʻi nā molekala "organic" i hoʻokumu ʻia i ke kaulahao lōʻihi) ʻo ia ka inoa e pili ana i ka ʻoiaʻiʻo i kā lākou semi-wai…
He aha ka hopena kemika o PVC?
Hana ʻia ʻo PVC me ka hoʻohana ʻana i kahi kaʻina i kapa ʻia ka polymerization hoʻohui.Wehe kēia pane ʻana i nā paʻa pālua i loko o ka vinyl chloride monomer (VCM) e ʻae ana i nā molekala pili e hui pū me ka hana ʻana i nā molekala kaulahao lōʻihi.nC2H3Cl = (C2H3Cl) n vinyl chloride monomer = polyvinylchloride
He aha nā waiwai kino o PVC?
Nā waiwai kino a me nā mīkini: ʻO PVC kahi polimer atactic a no laila ʻaʻohe crystallized.Eia nō naʻe, hiki i kekahi manawa, ma ka ʻāina, ma luna o nā ʻāpana kaulahao pōkole, he syndiotactic ka PVC a hiki ke lawe i ke ʻano crystalline, akā ʻaʻole i ʻoi aku ka hapa o ka haʻihaʻi shear ma mua o 10 a 15%.ʻO ka nui o ka PVC he 1.38 g / cm3.
