PVC Foam Board vs PVC Pepa: Nā ʻokoʻa koʻikoʻi no nā papahana kālepa a me nā ʻoihana

ʻElua mau mea hoʻolako e ʻōlelo i ka like 1220 x 2440 mm, panel 10 mm a hoʻi hou nā kumukūʻai pae ʻana i ʻekolu manawa kaʻawale. ʻAneʻane ʻaneʻane ʻaʻohe palena o ka ʻāpana. He mānoanoa. Holo ka pepa PVC paʻa ma ka 1.38 a 1.45 g/cm3, ʻoiai holo ka papa PVC foam manuahi ma 0.35 a 0.60 g/cm3, no laila, ʻo ka mānoanoa like he 2.4 a 4.1 manawa ʻokoʻa i ka nuipa, ka hoʻohana resin a me ka halihali ukana.

Puhi nā mea kūʻai ma nā ʻaoʻao ʻelua. Kākau ka mea hana ʻaelike i "pepa PVC" ma kahi kauoha kūʻai no kahi hōʻailona lobby a loaʻa iā ia kahi papa e haki ana ma lalo o ka manamana lima. Ke kauoha nei kekahi hale kūʻai kuhina i ka papa huʻihuʻi no ka gusset kūkulu ʻia a wehe ʻia nā wili wati ma kahi hapa o ka ukana i manaʻo ʻia. Hoʻomaka nā hemahema ʻelua me ka mālama ʻana i ʻelua ʻohana waiwai ma ke ʻano he laina laina hoʻokahi. Hoʻokaʻawale kēia hoʻohālikelike iā lākou e nā waiwai i hiki ke ana ʻia: ka hoʻolālā cell, density, paʻa paʻa, hoʻokaʻawale ahi, ʻano hana a me ke kumukūʻai no ka mika square.

ʻO ka ʻokoʻa hana e hoʻonohonoho i kēlā me kēia waiwai ʻē aʻe

ʻO ka hoʻolālā pūnaewele ka laina hoʻokaʻawale: hoʻonui ʻia ka papa puaʻa i ka wā extrusion a mālama i kahi cellular core, aʻo ka pepa PVC i extruded a calendered ma ke ʻano he pūhui piha piha. ʻO kēlā me kēia ʻokoʻa i lalo, mai ke kaumaha o ka panel a hiki i ka hoʻopaʻa ʻana i ka wili a me ka conductivity thermal, e hahai ana mai kēlā ʻano hana hoʻokahi.

Māhele ʻia ka papa puaʻa i ʻekolu mau ʻohana. ʻO ka huʻa manuahi, kūʻai ʻia ma lalo o nā inoa e like me Forex, Sintra a me Sunboard, loaʻa i kahi ʻano cellular core a me nā ʻāina ma waena o 0.35 a me 0.50 g/cm3. ʻO Celuka, i kākau pū ʻia ma ke ʻano he cellular a crust foam, i hana i ka ʻili hoʻohui nui ma luna o ke kumu pahu a holo ka 0.55 a 0.80 g/cm3. Hoʻopaʻa ʻia ka ʻili paʻa i hoʻokaʻawale ʻia i ka ʻiʻo i hoʻopaʻa ʻia i ka ʻili i hoʻopaʻa ʻia ma luna o kahi kumu i hoʻāla ʻia, e hoʻokiʻekiʻe aʻe i ka paʻakikī o ka ʻili a hoʻopuka i nā helehelena hiki ke paʻi ʻia i UV e hilinaʻi ʻia ai ka hana hoʻolaha. ʻO ka pepa PVC paʻa he ʻohana huahana hoʻokahi: paʻa piha, hiki ke hoʻoheheʻe ʻia, a hana ʻia e like me ka pā metala palupalu.

PVC Celuka Foam Papa no na Lako a me na Keena ʻO ka papa puaa PVC paʻa kiʻekiʻe ma 3-17 mm mānoanoa, kūpono i nā keʻena keʻena, nā papa, a me nā papahana lako hale a i waho paha. Nānā Huahana →

Manaʻo ka Density i ka ikaika, ke kaumaha a me ka hana wela

ʻO ka Density ka mea wanana hoʻokahi ikaika loa o ka ʻano o ka panel: ʻo ka pālua ʻana i ka nui o ka pahu mai ka 0.40 a i ka 0.80 g/cm3 e pāpālua i ka ikaika compressive a me ka ʻoʻoleʻa flexural oiai e waiho ana i ka panel 43 pakeneka māmā ma mua o ka pepa PVC paʻa i ka mānoanoa like.

Ma ka 10 pakeneka deformation, he 0.5 g/cm3 foam core e lawe ana ma kahi o 3 a 6 MPa i ke kaomi. ʻO ka pepa PVC paʻa o ka mānoanoa like me 55 MPa a ma luna. ʻO kēlā āpau ke kumu i hoʻohana ʻia ai ka pepa paʻa no ka lawe ʻana i nā papa, nā milo i hana ʻia a me nā spacers hoʻolālā, a ʻaʻole hoʻi ka papa pahu. Noho ka hana Kuhina ma waena o nā mea ʻelua: 15 a 18 mm papa co-extruded ma 0.55 a 0.65 g/cm3 hāʻawi i kahi ʻili paʻakikī no ka lako puka me ka mālama ʻana i ka māmā o ka panel no ka hoʻoponopono ʻana.

Papa Pua PVC Hoʻohuihui no nā Keʻena a me nā Lako ʻO ka papa pahu pahu PVC i hoʻokuʻu ʻia i ka papa Kuhina, 3-18 mm, me nā ʻili laminate-mākaukau maʻemaʻe, nā ʻāpana paʻa, a me ka hana ʻana e CNC routing, ʻili, wili, a pena. Nānā Huahana →

Holo ka hana wela ma ka ʻaoʻao ʻē aʻe. Hoʻopaʻa paʻa ka cellular core i ka ea a hāʻule i ka conductivity i 0.035 a i 0.045 W/mK, kūʻē i ka 0.16 a i 0.19 W/mK no ka pepa paʻa. ʻO kēlā ʻāpana ʻehā ʻehā ke kumu i kuhikuhi ʻia ai ka papa puaa 10 a 20 mm no nā lining hale kūʻai anu, nā panela kaʻa i hoʻopaʻa ʻia a me nā pahu hōʻike insulated, ʻoiai ʻo ka pepa paʻa e hana ma ke ʻano he alahaka wela ma nā wahi āpau i ʻike ʻia ma ka pā hoʻokahi.

Hana: CNC Feeds, Hoʻopaʻa a hoʻopaʻa

ʻEkolu a ʻehā mau manawa ʻoi aku ka wikiwiki o nā mīkini papa pahu ma mua o ka pepa PVC paʻa, akā koi ʻo ia i nā mea hana like ʻole, nā mea hoʻopili a me nā mea hoʻopaʻa, ʻaʻole hiki ke hoʻopaʻa ʻia i loko o kahi hui e like me ka PVC hiki.

1. ʻO ka hoʻokele CNC. Hoʻomaʻemaʻe ka bit upcut ʻelua 6 mm i ka papa pahu ma 18,000 rpm a me 3 a 5 m i kēlā me kēia minuke. Pono ka pepa PVC paʻa i ka geometry O-flute hoʻokahi-flute ma 1 a 1.5 m i kēlā me kēia minuke me ka ea ikaika, no ka mea e palupalu ka puʻupuʻu a hoʻihoʻi i ka ʻoki me ka ʻole o ka hoʻomaha.
2. ʻO ka wili ʻana a me ka hoʻopaʻa ʻana. ʻO ka huki ʻana i waho o ka ʻūhā 18 mm ka nui o ka ʻāpana o ka ʻōpala paʻa. E hoʻohana i nā bolts, nā mea hoʻokomo i hoʻopaʻa ʻia a i ʻole ke alo i hoʻopaʻa ʻia ma nā wahi a pau e pono ai ka hui e lawe i ka ukana a i ʻole e wehe ʻia i ka lawelawe.
3. Hoʻopaʻa a me ka wili. Hoʻopaʻa ʻia ka pepa PVC paʻa me ka tetrahydrofuran a i ʻole cyclohexanone solvent cement i loko o kahi hui ʻoi aku ka ikaika ma mua o ka mea makua. Pono ka papa foam i ka cyanoacrylate haʻahaʻa viscosity a i ʻole ka mea hoʻoheheʻe PVC i hoʻopili ʻia me ka hoʻopaʻa māmā, no ka mea, hoʻopili ka ʻaoʻao kelepona i ka mea hoʻopili a pōloli i ka laina paʻa.
4. Thermoforming. Hoʻomaʻemaʻe ʻia ka pepa paʻa ma 160 a 200 degere C. Hiki ke hoʻokumu ʻia ka papa puaa ma 120 a 150 degere C, akā ʻoi aku ka ʻili o ka ʻili ma luna o 160 degere C.
5. Hoʻopau ʻili. Maʻemaʻe ka lihi pepa paʻa i hana ʻia a hiki ke hoʻomāliʻi ʻia. Hōʻike ka papa puaʻa i nā pūnaewele a pono e hoʻopaʻa ʻia a i ʻole kahi pāpale ʻoki.

Ke ahi, kemika a me ke ano ea

ʻO nā mea ʻelua he mea pale ahi maoli, no ka mea, lawe ʻo PVC paʻa i ka 57 pākēneka chlorine ma ke kaupaona a hiki i kahi helu oxygen palena kokoke i 45. ʻO ka ʻokoʻa kūpono ke ʻano o kēlā me kēia mea i loko o kahi hui i hoʻāʻo ʻia.

Hōʻike maʻamau nā pūhui PVC paʻa i ka helu ASTM E84 lapalapa ahi o 15 a 25, akā holo ka uahi i nā waiwai 300 a 450. ʻAʻole paʻa ka papa UL 94 V-0 ka UL 94 V-0 ma nā ana ma lalo o 6 mm, no ka mea, ʻoi aku ka wikiwiki o ka ʻili o ke kelepona ma mua o ka ʻili. Ke komo ka luna code, e kuhikuhi i ka hui i helu ʻia ma mua o ka inoa mea.

ʻO ke kūʻē kemika kokoke i ka like. Hoʻohana ʻia nā ʻohana ʻelua i nā ʻakika wai, alkalis, nā paʻakai a me nā ʻawaʻawa, a ua hoʻouka ʻia ʻelua e nā ketones e like me ka acetone a me ka methyl ethyl ketone, e ka tetrahydrofuran, e nā solvents chlorinated a me nā hydrocarbons aromatic. E mālama i ka papa puaa ma ke ʻano he spacer, ʻaʻole loa ma ke ʻano he pale kemika.

Hoʻokaʻawale ka lawelawe waho iā lākou. ʻO ka pepa PVC paʻa me ka 4 a i ka 6 phr titanium dioxide a me kahi pūʻolo UV stabilizer e paʻa mau i ka kala a me ka ikaika hopena no 5 a 10 mau makahiki o ka hoʻolaha pololei. ʻAʻole i hoʻopaʻa ʻia a paʻa māmā ʻia nā peni a me nā melemele i loko o 12 a 18 mau mahina, a hiki i kona ʻili ke hoʻoheheʻe i kahi e ʻā ai ka maka i ka makani.

Ke Kumukūʻai Kūʻai ʻāina: Ma kahi e nalowale ai ke kumu kūʻai

He 2.5 a 3.5 ka nui o ka pepa PVC paʻa no ka mika square ma mua o ka papa puaa ma ka mānoanoa like, akā, ʻoi aku ka hapalua o ia uku i ka wā e helu ʻia ai ka ukana moana ma ka uku ma mua o ke kumu kūʻai.

Loaʻa i kahi pahu 40-kapuaʻi ka 26 a i ka 28 tonnes o ka ukana. Ma ka 5.5 kg o ka mika square, hoʻopiha ʻia ka papa puaa 10 mm me kahi 4,700 m2. ʻO ka pepa paʻa ma 14 kg no ka mika square piha i ka 1,850 m2. ʻO ka mea kūʻai aku e hoʻouna ana i ka pepa paʻa e uku no 2.5 manawa e like me ka nui o nā pahu e neʻe i ka ʻāpana like, kahi e hoʻololi pono ai i ka hoʻohālikelike maoli mai ka laina invoice.

• Kākau i ka mānoanoa ma ke kauoha kūʻai. ʻAʻole kikoʻī ʻo "Pepa PVC" wale nō, no ka mea, ʻo 0.55 g/cm3 a me 1.40 g/cm3 nā huahana like ʻole ma nā kumukūʻai like ʻole.
• Hōʻike i ka mānoanoa hoʻomanawanui. ʻO ka pepa paʻa maʻamau e paʻa i ka hoʻohui a i ʻole 0.2 mm; Hoʻohui pinepine ʻia ka papa puaa i ka 0.3 a i ka 0.5 mm.
• Koi i ka ʻōlelo hoʻopaʻa kepau ʻole. Mālama nā ʻōnaehana calcium-zinc i nā paneli i loko o nā palena REACH SVHC a me RoHS, he mea nui ia no ka lawe ʻana mai ʻEulopa a me ʻAmelika ʻĀkau.
• E mālama i ka hōʻike hoʻāʻo ʻekolu ʻaoʻao ma ka waihona like me ka papa inoa packing, ʻaʻole i kanu ʻia i loko o kahi leka uila.

Hoʻolikelike i nā mea me ke ʻano o ka papahana

E hoʻokūkū i ka pahu ukana, ʻaʻole ma ka maʻamau: lanakila ka papa puaa ma nā wahi a pau e paʻa ai ke kaumaha, ka insulation a i ʻole ka paʻi paʻi ʻana, a lanakila ka pepa paʻa ma nā wahi a pau e lanakila ai nā mea hoʻopaʻa, nā kaula a i ʻole nā ​​pili kemika.

Pepa Sintra PVC hiki ke paʻi ʻia UV no nā papa hōʻailona a me nā hae ʻO ka papa ʻōhua PVC kiʻekiʻe ʻo Sintra me kahi ʻili paʻi UV matte, hiki ke koho ʻia 0.4–0.8 g/cm³ mānoanoa, no nā papa hōʻailona, nā hae, nā hōʻike POP, a me nā kiʻi hōʻikeʻike. Nānā Huahana →

No ka hōʻailona pāʻoihana, uhi ʻia kahi papa paʻi UV 5 mm ma 0.55 g/cm3 i ka hapa nui o ka lobby a me ka hana hōʻike. Hoʻohālikelike ʻia nā hale kūʻai Kuhina ma ka 15 a 18 mm co-extruded a i ʻole ka papa Celuka kokoke i 0.60 g/cm3. Hoʻopuka ʻo Hangzhou Jiatao Industrial Co., Ltd. i nā ʻohana ʻelua mai kahi mea kanu 11,000 square meter me ka nui o 25,000 tonnes o ka nui o ka papa PVC makahiki, a ʻo kāna mau laina extrusion e uhi ana i ka mānoanoa mai 3 mm a 330 mm ma waena o ka pahu manuahi, Celuka, co-extruded, kala a me nā māka WPC.

Nīnau Koho Nā mea kūʻai aku ma mua o ke kauoha ʻana

Hiki i ka PVC foam board ke hoʻololi i ka pepa PVC paʻa i kahi ʻāpana haʻahaʻa?

ʻAʻole, ʻaʻole ma kahi o kahi mea hoʻopaʻa a i ʻole ke kaula mīkini e lawe ai i ka ukana. Hāʻawi ʻia ka pahu pahu ma 0.55 g/cm3 ma kahi o ka hapakolu o ka huki ʻana i waho o ka pepa paʻa ma 1.40 g/cm3. ʻO ka foam board ka koho kūpono no ka hoʻopaʻa ʻana i nā panela, e hoʻemi ana i ka nui a me ka lawe ʻana i ka insulation, ʻoiai ʻo ka pepa paʻa ka mea i koho ʻia no nā brackets, bearing pads a me nā hui i wehe ʻia i ka lawelawe.

He aha ka nui e pono e kuhikuhi ʻia no nā hōʻailona waho ma kahi pāhana kalepa?

E wehewehe i ka 0.55 g/cm3 a i ʻole ke kiʻekiʻe, me ka maka UV-stabilized a me ka hoʻouka ʻana o ka titanium dioxide o 4 a 6 phr. ʻO ka huʻa manuahi ma lalo o 0.50 g/cm3 nalo ka ikaika a me ka peni i loko o 12 a 18 mahina o ka lā pololei. ʻO kahi papa 0.55 a 0.65 g / cm3 i hoʻopaʻa ʻia me kahi maka i paʻi ʻia a laminated ka mea maʻamau no kahi hōʻailona waho ʻelima makahiki.

No ke aha i kūlike ʻole ai ka papa i hāʻawi ʻia me ke kiʻi?

I ka hapanui o nā hihia, ʻōlelo ʻia ke kauoha kūʻai "PVC sheet" a ʻaʻohe mea ʻē aʻe. ʻOkoʻa ka papa foam a me ka pepa paʻa ma kahi helu o 2.5 i ka nuipa ma ka mānoanoa like 10 mm, a ma 2.5 a 3.5 mau manawa i ke kumukūʻai. Kākau i ka mānoanoa i ka grams no cubic centimeter, ka mānoanoa me ka hoʻomanawanui, a me ka mālama ʻana i ka ʻili i loko o ka kikoʻī, a nalowale ka ambiguity i ka pae ʻōlelo.

ʻOi aku ka liʻiliʻi o ka papa foam i ka wā e hoʻokomo ʻia ai ka ukana a me ka hoʻokomo ʻana?

ʻAe, ma ka palena ākea ma ka hana papa pālahalaha. Lawe ʻia kahi pahu 40-kapuaʻi ma kahi o 4,700 m2 o 10 mm foam board ma 0.55 g/cm3 me ka 1,850 m2 o ka pepa paʻa ma 1.40 g/cm3, no ka mea, ua kaupalena ʻia nā ukana ʻelua e ka 26 a 28 tonne uku. ʻOiai me ke kumu kūʻai waiwai he 3 mau manawa kiʻekiʻe, ʻoi aku ka nui o ke kumu kūʻai o ka pepa paʻa no kēlā me kēia mika square i hoʻokomo ʻia ma kekahi noi ʻaʻole koi maoli i kona mānoanoa.
