PVC Cellular Foam Papa: Ka wai, ke ahi, ka hoʻohana ʻana i ke kaupaku a me ke ʻano o ka hana ʻana

Pane wikiwiki: Pvc cellular foam papa he paʻa paʻa, pani-cell polyvinyl chloride panel i hana ʻia ma o ke kaʻina extrusion mau a me ka huʻa. ʻAʻole ia e komo i ka wai (ma lalo o 1% ma ka leo ma ka hapa nui o ka nui), hoʻopau iā ia iho a hoʻopaʻa ʻia ʻo ia ka pale ahi ma lalo o nā kūlana honua, a hiki ke hoʻohana ʻia i nā noi kaupaku - ʻoiai pono ia e hoʻokaʻawale ʻia mai nā papa insulation foam palupalu, e lawelawe ana i kahi hana ʻokoʻa a me ka hana wela. Hāʻawi kēia alakaʻi i kēlā me kēia nīnau koʻikoʻi me ka ʻikepili kikoʻī a me ke alakaʻi kūpono.

Pehea i hana ʻia ai ka papa pahu PVC

Hana ʻia ka Pvc cellular foam papa ma o ka hoʻomau extrusion foaming process ka mea e hoʻololi i ka puʻupuʻu PVC maka i loko o kahi pānaʻi paʻa, māmā me kahi ʻano paʻa i loko. ʻO ka hoʻomaopopo ʻana i ke kaʻina hana e wehewehe ana i ka hapa nui o nā hiʻohiʻona hana o ka mea - ʻo kona kaumaha haʻahaʻa, ka ʻili laulima, ka pale ʻana i ka makū, a me ka paʻa ʻana o ka nui e hoʻi pololei i ke ʻano i hana ʻia ai.

Huina Mea Maka

ʻO ka waihona kumu i hānai ʻia i loko o ka extruder ʻaʻole ia he resin PVC maʻemaʻe. ʻO ia kahi hui i hoʻonohonoho ʻia e komo pū me:

• PVC resin (K-waiwai 55–68): ʻO ka matrix polymer mua. ʻOi aku ka nui o nā K-waiwai haʻahaʻa (55–60).
• Nā mea hoʻoheheʻe kemika (CBA): ʻO ka mea maʻamau ʻo azodicarbonamide (ADC) a i ʻole nā ʻōnaehana kumu sodium bicarbonate. Hoʻopau kēia mau mea ma ka hoʻoponopono ʻana i nā mahana (170–200°C) e hoʻokuʻu i ke kinoea nitrogen a i ʻole carbon dioxide e hana ai i ke ʻano kelepona.
• Nā mea hoʻopaʻa paʻa: ʻO nā stabilizer e pili ana i ke alakaʻi ʻo ia ke kūlana mōʻaukala akā ua hoʻololi nui ʻia e ka calcium-zinc (Ca-Zn) a i ʻole nā ʻōnaehana organotin i nā mākeke me nā koi hoʻokō RoHS a me REACH.
• Nā mea kōkua a me nā lubricants: ʻO nā mea kōkua kaʻina hana Acrylic e hoʻomaikaʻi i ka ikaika heheʻe a me ka like o ke kelepona; ʻO nā lubricants waho a me loko e hoʻomalu i ka fusion a me ka hoʻokuʻu make.
• Nā mea hoʻololi hopena: ʻO ka polyethylene chlorinated (CPE) a i ʻole nā mea hoʻololi i ka hopena acrylic e hoʻonui i ka paʻakikī, ʻoi aku ka mea nui ma nā māka haʻahaʻa haʻahaʻa.
• Nā mea hoʻopiha: Hoʻohui ʻia ka calcium carbonate (CaCO₃) i kekahi mau mea hoʻohālikelike e hōʻemi i ke kumukūʻai a hoʻomaikaʻi i ka maʻalahi o ka ʻili.

Ke Kaʻina Celuka vs. Free-Foam (Straight Extrusion).

ʻElua mau ʻano extrusion nui e hana i ka PVC foam board, a hāʻawi lākou i nā huahana like ʻole:

ʻO ke kaʻina hana Celuka e hana i ka papa hana kiʻekiʻe no ka hoʻohana ʻana i ka hana a me ka hana. ʻO ka ʻili paʻa paʻa i hana ʻia e ka mandrel maloʻo e hāʻawi i nā papa Celuka i ko lākou ʻano maʻemaʻe a hiki ke pena a hiki ke machinable me nā mea hana lāʻau maʻamau me ka ʻole o ka haehae ʻana.

Mai Extruder a hiki i ka Panel Hoʻopau

• Hoʻokomo ʻia ka hui ʻana o PVC i loko o kahi extruder māhoe-screw, kahi i hoʻoheheʻe ʻia a hoʻohui ʻia ma 160–200°C .
• Holo ka hehee ma ka lau palahalaha, kahi o ka puhi ana i ka decomposition i ka manawa pono e hiki ai ma ka puka make (free-foam) a i ole ia e hoomaluia e ka mandrel kūloko (Celuka).
• Hoʻokomo ʻia ka ʻōpala i loko o kahi ʻāpana calibration - he papa ʻaina nui i hoʻoluʻu ʻia i ka wai me nā mānoanoa e hoʻopaʻa i ka panel i ka mānoanoa pololei i ka wā e paʻa ai ka hale kelepona.
• Hele ka panel i loko o ka pahu hoʻoluʻu a me ka ʻāpana haul-off, a laila komo i kahi ʻike lele a i ʻole guillotine e ʻoki ai i ka lōʻihi o ka pepa - maʻamau 2440 mm × 1220 mm (8 ft × 4 ft) a i ʻole 3050 mm × 1220 mm (10 ft × 4 ft).
• Hoʻopaʻa ʻia nā lau, nānā ʻia no ka like like ʻana a me ka maikaʻi o ka ʻili, a hoʻopaʻa ʻia. ʻO ka like ʻana o ka density ma waena o kahi panel kahi hōʻailona koʻikoʻi nui - mālama nā papa premium i nā ʻano like ʻole i loko ±5% ma kahi o ka lau.

Hiki i ka PVC Foam ke hoʻopau i ka wai?

ʻAʻole - He haʻahaʻa haʻahaʻa loa ka haʻahaʻa ʻana o ka wai o ka papa cellular foam PVC, e hoʻolilo iā ia kekahi o nā mea paʻa paʻa paʻa paʻa loa i loaʻa. ʻO kēia kekahi o kāna mau mea maikaʻi ma mua o nā mea hoʻokūkū e like me MDF, plywood, particleboard, a me nā huahana foam hoʻokūkū.

ʻO ka hoʻolālā paʻa-paʻa e wehewehe i nā mea a pau

ʻO ka hale paʻa o ka PVC foam board he mau miliona o kēlā me kēia keena piha piha i ke kinoea, kēlā me kēia i hoʻopaʻa piha ʻia e nā pā kelepona PVC lahilahi. ʻAʻole e like me nā huʻa hāmama (e like me ka polyurethane sponge foam), ʻaʻohe ala pili e hiki ai i ka wai wai ke wick a i ʻole ke kahe capillary. Hiki i ka wai ke hoʻopili i ka ʻili o waho a me nā ʻaoʻao ʻoki o ka pā - ʻaʻole hiki ke neʻe i loko o ke kino o ka papa.

ʻIke ʻikepili hoʻoheheʻe wai mai ka hoʻāʻo maʻamau (ISO 62 a i ʻole ASTM D570, 24-hola immersion):

• Pvc cellular foam papa: 0.1–0.5% ma ke kaumaha (ka hapa nui o nā māka ma lalo o 0.3%)
• MDF (papa fiber-density): 15–30% ma ke kaumaha me ka pehu ʻike ʻia a me ka delamination
• Plywood waho: 10–20% ma ke kaumaha ma muli o ke ʻano o ke kāpili a me nā ʻano veneer
• ʻO ka papa ʻāpana maʻamau: 20–40% ma ke kaumaha , me ka pehu mānoanoa nui
• Papa sima: 8–15% ma ke kaumaha

No ka hoʻāʻo ʻana i ka hoʻāʻo lōʻihi, ʻoi aku ka liʻiliʻi o ka papa pahu PVC ma mua 1% ma ka leo ʻoiai ma hope o ka hoʻohaʻahaʻa ʻana i nā lā he 28 - kahi pae hana e kūpono ai i nā wahi pulu mau kahi e pau ai nā paneli kumu lāʻau i loko o nā pule.

Nā Manaʻo Hoʻomaʻamaʻa o ka Haʻahaʻa Wai

• ʻAʻohe pehu a i ʻole ka ʻāʻī ʻana ma nā kihi: Pehu nui nā panela lāʻau ma nā ʻaoʻao i ʻoki ʻia i ka wā e komo ai ka wai i ka palaoa hope. ʻO nā ʻaoʻao ʻokiʻoki ʻo PVC e like me ka maka.
• ʻAʻohe ʻōpala a ulu ʻole paha: ʻO ka PVC kahi polymer synthetic ʻaʻole hāʻawi i nā meaʻai no ka poʻo, ka maʻi, a me nā meaola pala. Hoʻohui pū ʻia me kona haʻahaʻa haʻahaʻa haʻahaʻa, ʻaʻole e kākoʻo ka papa puaʻa PVC i ka ulu ʻana o ke ola - he pōmaikaʻi nui i nā lumi ʻauʻau, nā lumi kuke, a me nā kaiapuni kai.
• Paʻa manaʻo: No ka mea, ʻaʻole e komo ka papa i ka makū, ʻaʻole ia e komo i ka hoʻonui ʻana o ke kau a me nā pōʻai hoʻokaʻawale e hoʻoheheʻe ʻia nā paneli kumu lāʻau i ka wā.
• ʻAʻole koi ʻia kahi hoʻopaʻa lihi kūikawā: ʻAʻole like me MDF, kahi e koi ai i ka priming lihi a me ka sila ʻana ma mua o ka pena ʻana i nā wahi haʻahaʻa, hiki ke waiho ʻia nā ʻaoʻao ʻoki ʻoki ʻo PVC me ka ʻole i ka nui o nā noi o loko.

Hoʻokahi Hōʻike: Hoʻopā ʻili

ʻOiai ʻaʻole e komo ka papa ponoʻī i ka wai, hiki ke hoʻokumu ʻia ka condensation o ka ʻili ma luna o nā panela puʻupuʻu PVC anuanu ma nā wahi haʻahaʻa, e like me ka hana ʻana ma luna o kekahi ili anu. I nā noi i hiki ke hoʻohālua - e like me ke kāʻei ʻana o waho a i ʻole nā ​​lining hale mālama anu - pono e noʻonoʻo ʻia ka ʻili o ka papa no nā kikoʻī wai kūpono a i ʻole ka hoʻokele mahu.

Hiki ke wela ka PVC Foam Board?

Pvc cellular foam papa is classified as self-extinguishing and flame retardant — it does not sustain combustion once the ignition source is removed. Eia nō naʻe, ʻaʻole hiki ke hoʻopau ʻia, a ʻo kāna ʻano i ke ahi e pono ai ka ʻike ʻoi aku ka nuanced ma mua o kahi binary flammable/non-flammable maʻalahi.

No ke aha i loaʻa ai i ka PVC ke kūpaʻa ahi

Aia ma kahi o ka polymer PVC 57% chlorine ma ke kaumaha - kekahi o nā mea chlorine kiʻekiʻe loa o kēlā me kēia palaki hana maʻamau. Hana ʻo Chlorine ma ke ʻano he mea pale ahi maoli ma o nā hana ʻelua:

• ʻO ka hoʻopau ʻana i nā radical manuahi: I ka wā o ka puhi ʻana, hoʻokuʻu ʻia nā ʻātoma chlorine mai ka decomposing PVC i ka hydroxyl (OH·) a me ka hydrogen (H·) manuahi manuahi e hoʻolaha ana i ka kemika lapalapa, e keakea ana i ka hopena o ke kaulahao puhi.
• Hoʻokumu Char: Hana ʻia ka PVC ma mua o ka hoʻoheheʻe ʻana a me ke kahe ʻana, e hōʻemi ana i ka hana ʻana o nā kulu wai ʻā ahi e hohola i ke ahi (he pōʻino nui me ka polyethylene a me ka polypropylene).

ʻO kēia maʻiʻo chlorine inherent 'o ia hoʻi, loaʻa i ka PVC foam board ka hoʻokaʻawale ʻana i ka lapalapa ahi me ka ʻole e koi ʻia i nā mea hoʻohui hou e pale ai i ka lapalapa - ʻaʻole like me ka polyurethane foam, polystyrene foam, a i ʻole polyethylene foam, e koi ana i ka hoʻouka mea hoʻohui kaumaha e hoʻokō i nā helu ahi like.

Nā Kūlana Kūlana ahi a me nā helu maʻamau

Ka Puka Uhi a me HCl Gas

ʻO ka mea koʻikoʻi koʻikoʻi i ka pale ʻana o ka lapalapa o PVC ʻo ia kona ʻano hoʻopau ʻana i ka huahana. Ke wela ka PVC, hana ia:

• Uahi ʻeleʻele nui: ʻOi aku ka nui o ka uahi ma mua o ka nui o nā mea hoʻokūkū. Ma lalo o EN 13501-1, ʻo ka hoʻohālikelike ʻana o ka uahi "s2" e hōʻike ana i ka ulu ʻana o ka uahi haʻahaʻa - kahi hopohopo maoli no ka ʻike a me ka haʻalele ʻana i ka palekana ma nā wahi paʻa.
• Ke kinoea hydrogen chloride (HCl): ʻO ka HCl he kinoea ʻawaʻawa a ʻino e hana ʻia i ka wā e wela ai ka PVC. Ma ka hoʻokuʻu ʻana ma luna o 5 ppm ke kumu ia i ka ʻeha hanu; ma luna o 50 ppm ua pilikia koke. Ma ke kūkulu ʻana i ke ahi, hoʻopilikia pū ʻo HCl i ka pōʻino ʻino i nā mea uila a me nā metala.

ʻO kēia mau hiʻohiʻona, ʻaʻole pono e hoʻohana ʻia ka PVC foam board i nā noi kahi e ʻike ʻia ai nā wahi nui me ka ʻole o nā ʻōnaehana kinai ahi e hana ai i ka uwahi a i ʻole ka pōʻino kinoea - ʻoi aku ka nui o nā wahi i hoʻopaʻa ʻole ʻia a i ʻole nā ​​noi kokoke i nā uila uila. No nā wahi e pili ana i ke ahi, ʻo nā mea pānaʻi haʻahaʻa haʻahaʻa zero-halogen (LSZH) ke koho kūpono.

Hoʻohālikelike me nā mea hana ʻē aʻe o ka papa puaʻa

Hiki ke hoʻohana ʻia ka Papa Foam ma nā lei?

ʻAe - Hoʻohana nui ʻia ka PVC cellular foam board i nā noi kaupaku, a ua kūpono maoli ia no ke kumu. Eia nō naʻe, ʻokoʻa ka pane ma muli o ka pili ʻana o ka nīnau i ka PVC foam board ma ke ʻano he papa hoʻonaninani a i ʻole ke kūkulu ʻia ʻana o ke kaupaku me nā papa insulation foam paʻa i hoʻohana ʻia ma luna a i ʻole ma loko o nā hui kaupaku. ʻO kēia nā huahana like ʻole me nā profile hana like ʻole.

ʻO ka Pvvv Cellular Foam Papa ma ke ʻano he Panel Ceiling

Ma ke ʻano he pānaʻi i hoʻopili ʻia a hoʻopaneʻe ʻia paha, hāʻawi ka PVC cellular foam board i kahi hui ikaika o nā waiwai:

• ʻO ke kaumaha haʻahaʻa e hoʻemi ana i ka noi hale: Ma ka 0.55–0.75 g/cm³, he 5 mm ma'amau o ka PVC foam ceiling panel ma kahi o ke kaumaha. 2.75–3.75 kg/m² - ʻoi aku ka māmā ma mua o ka papa gypsum (drywall ma ~ 10 kg/m² no 12.5 mm) a hoʻohālikelike ʻia me nā tile kaupaku PVC maʻamau. Hoʻemi kēia i ka hoʻouka ʻana ma ka hoʻopili ʻana i ke kaupaku a maʻalahi ka hoʻonohonoho ʻana, ʻoi aku hoʻi no nā retrofits.
• ʻO ka pale ʻana i ka wai no nā wahi pulu: ʻO nā lumi ʻauʻau, nā lumi kuke pāʻoihana, nā ʻauʻau ʻauʻau, a me nā mea kanu meaʻai e hoʻohana maʻamau i nā kaupaku o ka PVC foam board ma muli o ka emi ʻana o ka papa gypsum maʻamau i nā wahi haʻahaʻa haʻahaʻa. ʻAʻole hāʻule, ʻeleʻele, a ulu paha ka ʻōpala PVC i ka wā e ʻike ʻia ai i ka mahu a me ka condensation.
• ʻili paheʻe, hiki ke pena: Hoʻopuka nā papa hana Celuka i kahi ʻili e ʻae i nā pena acrylic me ka solvent-free ma hope o ka hoʻomaʻamaʻa māmā ʻana, e ʻae ana i ka hoʻololi nani e like me ka plasterboard pena.
• Maʻalahi o ka ʻoki ʻana a me ka hoʻopili ʻana: Hiki ke ʻoki ʻia ka papa puaa PVC me ka lima niho niho maikaʻi, ʻike pōʻai, a i ʻole ka mea alaala e hoʻohana ana i nā mea hana lāʻau maʻamau, e hiki ai ke hoʻomaʻemaʻe ʻia a puni ke komo ʻana o ke kaupaku, nā kukui kukui, a me nā mea hana me ka ʻole o nā lako loea.
