Hoʻolauna i ka Uea PVC haʻahaʻa a me nā hui kelepona

ʻO ka uahi haʻahaʻa PVC (Polyvinyl Chloride) uea a me nā pūhui uwea he mea thermoplastic kūikawā i hoʻolālā ʻia e hōʻemi i ka uahi a me ka hoʻokuʻu ʻana i ke kinoea ʻona i ka wā o ka puhi ʻana. Hoʻolilo kēia iā lākou i koho koʻikoʻi no nā noi kahi mea nui ka palekana ahi. Hoʻohana maʻamau no ka insulation a me ke kāʻei ʻana i nā kaula uila, hāʻawi kēia mau pūhui i nā hiʻohiʻona nui:

Huina:Hoʻokumu ʻia nā pūhui PVC uahi haʻahaʻa me ka hui pū ʻana o PVC resin, plasticizers (e like me ka dioctyl phthalate a me tri-2-ethylhexyl trimellitate), nā mea pale ahi (eg, antimony trioxide, aluminum trihydrate, a me zinc borate), stabilizers (calcium/zinc-based), fillers (calcium carbonate), a me nā lubricants.

Nā ʻano uahi haʻahaʻa:ʻAʻole like me ka PVC maʻamau, hiki ke hōʻemi i ka ʻike a hiki i ka 90% i nā minuke 30 wale nō ma muli o ka uahi nui, ua hana ʻia nā puʻupuʻu PVC haʻahaʻa e hoʻokō i nā kūlana palekana e like me BS EN 61034. ʻO kēia mau pūhui e ʻae i ka liʻiliʻi o 60% ka transmittance māmā i ka wā o ka puhi ʻana, hoʻomaikaʻi nui i ka palekana.

Hoʻopaʻa ahi: Loaʻa i ka PVC nā waiwai pale ahi ma muli o kona ʻano chlorine, i hoʻonui ʻia me nā mea hoʻohui ahi. Hoʻokō kēia mau pūhui i nā kūlana koʻikoʻi e like me IEC 60332-1-2, UL VW1, a me E84 (induse laha ahi <25, uahi hoʻomohala index <50).

 Nā noi:Hoʻohana maʻamau ʻia i nā kaiapuni kiʻekiʻe e like me nā kikowaena data, tunnels, mokulele, kaʻa kaʻa, a me nā hale aupuni, ʻo ka uahi PVC haʻahaʻa a me nā pūhui uwea he mea nui no ka hōʻemi ʻana i nā pilikia e pili ana i ka uahi a me nā uahi ʻawaʻawa i ke ahi.

Nā Luʻi Hana maʻamau a me nā mea hoʻonā no ka Uea PVC haʻahaʻa a me nā hui kelepona

ʻO ka hana ʻana i nā pūhui PVC uahi haʻahaʻa e pili ana i ka hoʻokele ʻana i nā ʻano paʻakikī, ʻoi loa ma muli o kā lākou hana paʻakikī. Ma lalo nei, kūkākūkā mākou i kekahi o nā pilikia kaʻina hana maʻamau a me kā lākou hoʻonā:

1. Kiʻekiʻe Filler Content Alakaʻi i ka Poor Mobility a High Torque

Paʻakikī:No ka loaʻa ʻana o nā waiwai uahi haʻahaʻa, loaʻa pinepine nā pūhui PVC i nā kiʻekiʻe kiʻekiʻe o nā mea hoʻopiha inorganic e like me ka alumini trihydrate (ATH) a i ʻole ka magnesium hydroxide (Mg(OH)₂) - maʻamau 20-60% ma ke kaumaha. ʻOiai e hōʻemi ana kēia mau mea hoʻopihapiha i ka uahi a me ka lapalapa, hiki iā lākou ke hoʻonui i ka viscosity, hōʻemi i ka kahe, a hoʻopau i nā mea hana.

Nā pane:

E hoʻohui i nā mea hana e like me nā lubricants o loko/waho (e laʻa, calcium stearate, polyethylene waxes, a i ʻole.mea hoʻohui silicone) ma 0.5-2.0 phr e hoʻohaʻahaʻa i ka viscosity a hoʻonui i ke kahe.

E hoʻohana i nā extruder māhoe māhoe L/D ratio kiʻekiʻe e hoʻomaikaʻi i ka hui ʻana a me ka hoʻopiha piha ʻana.

E hoʻohana i nā ʻōnaehana kneader me ka hānai ikaika conical e hōʻoia i ka hui pū ʻana.

E koho i nā mea hoʻopihapiha me ka nui o nā ʻāpana i hoʻomalu ʻia a me ka mālama ʻana i ka ʻili e hoʻomaikaʻi i ka hoʻohālikelike a hōʻemi i ka abrasion.

2. Paʻa wela

Paʻakikī:Hiki i ka PVC ke hoʻohaʻahaʻa i ka wā o ka hana ʻana, ʻoi aku ka nui o ka hoʻopiha piha a me nā haʻahaʻa ahi-retardant, e hoʻokuʻu ana i ke kinoea hydrogen chloride (HCl) e alakaʻi ai i ka hoʻohaʻahaʻa ʻana i nā mea waiwai, discoloration, a me nā mea hana.

Nā pane:

Hoʻohui i nā mea hoʻopaʻa wela e like me ka calcium/zinc-based stabilizers ma 2-4 phr e hoʻokaʻawale i ka HCl a pale i ka hōʻino.

E hoʻohana i ka ʻaila soy epoxidized (ESO) ma ke ʻano he co-stabilizer no ka hoʻomaikaʻi ʻana i ka wela a me ka paʻa kiʻi.

E hoʻomalu pono i nā mahana hoʻoponopono (160-190°C) e pale i ka wela.

Hoʻohui i nā antioxidants phenolic (e laʻa, Bisphenol A ma 0.3-0.5%) e hoʻoikaika i ke kūʻē ʻana i ka wā kahiko.

3. ʻO Plasticizer Migration

Paʻakikī:Hiki ke neʻe i nā mea hoʻolalelale i hoʻohana ʻia no ka hoʻonui ʻana i ka maʻalahi (e laʻa, ma nā kikowaena data), e alakaʻi ana i ke kūkulu ʻana i ke koena e hoʻopilikia i ka hoʻouna ʻana i ka hōʻailona a hōʻemi paha i ka lōʻihi o ke kaula.

Nā pane:

E hoʻohana i nā plasticizer polymeric non-migrating ma kahi o nā monomeric (eg, DOP, DINP) e hōʻemi i ka neʻe ʻana.

E hoʻomohala i nā palapala plenum "ʻaʻohe wai", e like me ka mea i hoʻokumu ʻia e OTECH, e pale i ka neʻe ʻana o ka plasticizer ma nā wahi wela kiʻekiʻe.

E koho i nā plasticizers e like me TOTM, he haʻahaʻa haʻahaʻa a ʻoi aku ka maikaʻi no nā noi wela kiʻekiʻe.

4. Ke kaulike ʻana i ka hoʻopaʻa ʻana i ke ahi a me ka hoʻopau ʻana i ka uahi

Paʻakikī:ʻO ka hoʻonui ʻana i ka lapalapa ahi ma o nā mea hoʻohui e like me ka antimony trioxide (3-5%) a i ʻole nā pūhui brominated (12-15%) hiki ke hoʻonui i ka hoʻokuʻu ʻana i ka uahi, no laila paʻakikī ke kaulike i nā waiwai ʻelua. Pēlā nō, hiki i nā mea hoʻopihapiha e like me ka calcium carbonate ke hōʻemi i ka uahi akā hiki ke hoʻohaʻahaʻa i ka helu o ka oxygen, e pili ana i ka hoʻopaʻa ahi.

Nā pane:

E hoʻohana i nā hui hoʻopaʻa ahi synergistic (e laʻa, ATH me ka zinc borate) e hoʻopaʻa pono i ka hoʻopaʻa ʻana o ka lapalapa a me ka hoʻopau ʻana i ka uahi. No ka laʻana, hoʻokuʻu ʻo ATH i ka mahu wai e hoʻopau i ka puhi ʻana a hana i kahi papa char pale, e hōʻemi ana i ka uahi.

E kaupalena i ka hoʻouka ʻana o CaCO₃ i ka 20-40 phr e hoʻopaʻa i ke kaulike ma waena o ke kumukūʻai, ka hoʻopaʻa ʻana i ka uahi, a me ka hoʻopaʻa ʻana o ke ahi, no ka mea, hiki i ka nui ke hōʻemi i ka helu o ka oxygen.

E ʻimi i nā hoʻohua PVC hiki ke hoʻopili ʻia, e like me ka PVC i hoʻopili ʻia i ka radiation, e hoʻoikaika i ka hoʻopaneʻe ahi me ka hilinaʻi nui ʻole i nā mea hoʻohui halogenated.

5. Hiki ke kaʻina hana a me ka maikaʻi o ka ʻili

Paʻakikī:Hiki i ka mea hoʻopihapiha kiʻekiʻe a me nā mea hoʻohui ke alakaʻi i ka hopena maikaʻi ʻole o ka ʻili, make drool, a me ka extrusion inconsistent, e pili ana i ke ʻano a me ka hana o ka huahana kelepona hope loa.

Nā hoʻonā:HoʻohanaSILIKE silicone pauda LYSI-100A. ʻO kēiamea hoʻohui siliconehoʻohana nui ʻia ma ke ʻano hemea hoʻohui hoʻoheheʻe ʻaila maikaʻino nā ʻōnaehana resin kūpono PVC e hoʻomaikaʻi i nā ʻano hana a me ka maikaʻi o ka ʻili. E like me ka maikaʻi o ka resin flowability, mold filling & release, liʻiliʻi extruder torque, a me ka haʻahaʻa haʻahaʻa o ka friction, ʻoi aku ka nui, a me ke kūpaʻa abrasion ...

ʻO nā pōmaikaʻi nui o ka silicone Powder LYSI-100A no nā pūhui PVC a me nā noi huahana hope loa:

1) Haʻahaʻa uahi PVC uea a me ka uwea pūhui: paʻa extrusion, emi make kaomi, laumania ili o ka uea & uwea.

2) Haʻahaʻa friction PVC uwea a me ka uwea: Haʻahaʻa Coefficient o Friction, lōʻihi-mau loa laumania manaʻo.

3) Huahana PVC kū'ē i ka'ōpala: Anti-scratch, e like me nā pani PVC.

4) Nā kiʻi PVC: ʻoi aku ka maikaʻi o ka hoʻopiha piha ʻana a me ka hoʻokuʻu ʻana, ʻaʻohe uila uila.

5) ʻO ka paipu PVC: ʻoi aku ka wikiwiki o ka extrusion wikiwiki, hoʻemi ʻia ka COF, hoʻomaikaʻi i ka maʻalahi o ka ʻili, a mālama ʻia ke kumukūʻai.

Inā ʻoe e alo nei i nā pilikia me ka hoʻoponopono ʻana i ka pūhui PVC a me nā hemahema o ka ʻili, a i ʻole e hakakā nei me ka uahi PVC haʻahaʻa a me ka hoʻoili uila, e hoʻāʻo.LYSI-100A Silicone Powder no ka extrusion maʻalahi a ʻoi aku ka maikaʻi.
