PVC Cellular Foam Board: He aha ia i hana ʻia ai a me ka mea i hoʻohana ʻia

Ka mea e pono ai e ike

Pvc cellular foam papa ʻO ia ka papa ʻaʻa māmā i hana ʻia mai ka polyvinyl chloride (PVC) resin i hoʻonui ʻia me kahi mea hoʻohāhā e hana i kahi hale paʻa. ʻAe - he plastic. Hana ʻia ia mai ka polymer PVC, e hana ana i ka synthetic piha, wai ʻole, a me ka pale kemika. ʻO kāna mea hoʻohana mua i ka hoʻopaʻa ʻia ʻana o ka span, ka hōʻailona, ​​​​ka hale keʻena, nā pale kai, a me nā papa hōʻike - ma nā wahi a pau e popopo ai ka lāʻau a i ʻole ka MDF.

ʻO PVC Foam Plastic?

ʻAe - ʻo ka ʻūhā PVC he mea palaki loa. No ka ʻohana thermoplastic, ʻo ia hoʻi, hiki ke hoʻonāwaliwali ʻia e ka wela a hoʻopaʻa hou ʻia me ka ʻole o ka hoʻololi kumu i kona ʻano molekala. ʻO ka polymer kumu - polyvinyl chloride - ʻo ia kekahi o nā plastic synthetic ʻekolu i hana nui ʻia ma ka honua, me ka polyethylene a me ka polypropylene.

ʻO ka mea e hoʻokaʻawale ai i ka ʻūhā PVC mai ka pepa PVC paʻa ʻo ia kona kikowaena pūnaewele. I ka wā o ka hana ʻana, hoʻokomo ʻia kahi kaʻina hana kemika a i ʻole ka hoʻoulu ʻana o ke kino i nā miliona o nā ʻōpū kinoea microscopic i loko o ka PVC i hoʻoheheʻe ʻia, a laila paʻa ʻia ma kahi i ka wā e maʻalili ai ka mea. ʻO ka hopena he papa me:

55% Kaumaha haʻahaʻa vs PVC paʻa o ka mānoanoa like
100% Paʻa wai - ʻaʻohe hoʻoheheʻe wai
0.55 ʻAno maʻamau (g/cm3) no ka papa maʻamau
60 ʻO nā makahiki i manaʻo ʻia ke ola lawelawe ma loko

No ka mea, he thermoplastic, hiki ke ʻoki ʻia ka papa ʻōhua paʻa PVC me nā mea hana lāʻau maʻamau, hoʻoheheʻe ʻia, hoʻoheheʻe ʻia, hoʻopaʻa wela, a wili ʻia me nā pū wili PVC wela - e ʻoi aku ka maikaʻi o ka hana ʻana ma mua o ka hapa nui o nā plastik loea.

He aha ka PVC Foam Papa?

ʻOi aku ka maikaʻi o ka hoʻokumu ʻana o ka PVC foam board ma mua o ka "PVC resin." Loaʻa i kahi hoʻolālā pāʻoihana maʻamau kekahi mau mea i kaulike pono ʻia, e lawelawe ana kēlā me kēia i kahi hana kikoʻī a i ʻole ka hana hana:

PVC Resin (K-Waiwai 65–68) 45–55%

Ka iwi kuamoʻo. ʻO kahi K-waiwai kiʻekiʻe e hōʻike ana i nā kaulahao polymer lōʻihi a hoʻomaikaʻi i ka ikaika mechanical. He mea maʻamau ka resine PVC hoʻokuʻu ʻia no ka hana ʻana i ka papa pahu.

ʻAi Hoʻohuʻi Kemika (Azodicarbonamide) 0.5–2%

Hoʻoheheʻe ʻia ma ka hoʻoponopono ʻana i nā mahana (180–200°C) e hoʻokuʻu i ke kinoea nitrogen, e hana ana i ke ʻano o ka pahu pahu paʻa. Hoʻoponopono pololei ka manaʻo i ka nui o ka papa hope loa - ʻoi aku ka nui o nā mea hana i ka haʻahaʻa haʻahaʻa.

Nā mea hoʻopaʻa wela me ke alakaʻi ʻole 3–5%

Kālepa-zinc a organotin stabilizers pale i ka PVC degradation i ka wā kiʻekiʻe-mehana extrusion. Ke hoʻohana nei nā papa o kēia manawa i nā hoʻolālā alakaʻi ʻole e hoʻokō i nā kuhikuhi RoHS a me REACH.

Kokua Hana Hana Acrylic 5–8%

Hoʻomaikaʻi i ka viscosity hehee a me ka hoʻohui like ʻana o nā cell foam. He mea koʻikoʻi no ka loaʻa ʻana o ka ʻili ʻili paʻakikī (ʻoi loa ma nā papa hana ʻo Celuka) ʻoiai e mālama ana i kahi kumu paʻa paʻa.

Nā mea hoʻopiha (Calcium Carbonate) 10–20%

Hoʻemi i ke kumu kūʻai kumu a me ka ʻoʻoleʻa. ʻO ka nui o ka CaCO3 e hoʻopilikia i ka ikaika o ka hopena - mālama nā mea hana maikaʻi i ka pale kaulike e mālama i ka hana mechanical.

Nā Lubricants a me nā mea hoʻololi hopena 2–4%

ʻO ka hoʻoheheʻe ʻana o ka lubricants i loko a me waho ma o ka make. Hoʻemi nā mea hoʻololi i ka hopena CPE a i ʻole ACR i ka brittleness - pono no nā papa i hoʻohana ʻia i ka piʻi anuanu a i ʻole nā ​​noi me ka haʻalulu mechanical.

ʻO ke Kaʻina Celuka vs ʻO ke Kaʻina Kūʻokoʻa-Foam: He aha ka ʻokoʻa?

15–18mm 0.60–0.70 g/cm3 ʻO nā kupapaʻu keʻena, nā papa, nā lako hale ʻauʻau
20–40mm 0.65–0.75 g/cm3 ʻO nā paneli kūkulu, nā poʻo moana, nā ʻāpana hana kaumaha

Nā nīnau maʻamau e pili ana i ka PVC Foam Board

Hiki ke hoʻohana ʻia ka papa pahu PVC ma waho o ka wā lōʻihi?
ʻAe. ʻO ka PVC foam board he UV maikaʻi loa a me ka pale ʻana i ka wā. Loaʻa i nā papa keʻokeʻo maʻamau nā titanium dioxide UV stabilizers a hiki ke mālama i ka hoʻolālā a me ka pono o ka ʻili no 10-15 mau makahiki ma waho me ka pena ʻole. Pono nā papa kala e hoʻohana i nā puaʻa paʻa UV a i ʻole nā ​​pale pale no ka lōʻihi like.
He palekana anei ka papa ʻaina PVC?
ʻAʻole nā ​​papa āpau. Hoʻohana ʻia nā papa puaa PVC i hoʻopaʻa ʻia i ka meaʻai i nā hoʻoponopono e like me nā lula FDA 21 CFR a i ʻole EU 10/2011, me ka ʻole o nā mea hoʻopaʻa metala kaumaha. E noi mau i ka pepa ʻikepili palekana a me ka palapala hōʻoia pili meaʻai inā e hoʻohana ʻia ka papa i ka hoʻomākaukau ʻana i ka meaʻai, mālama ʻana, a i ʻole nā ​​wahi hōʻike.
He aha ka helu ahi o ka PVC foam board?
Loaʻa ka hapa nui o nā papa puaa PVC pāʻoihana i ka helu ahi B1 (a i ʻole ka papa 1 like) - ʻo ia hoʻi ke kinai ʻana iā lākou iho a ʻaʻole e hoʻomau i ka lapalapa ke wehe ʻia ke kumu hoʻā. ʻOi aku ka maikaʻi o kēia ma mua o ka lāʻau i mālama ʻole ʻia a i ʻole ka polystyrene foam maʻamau. No ka hoʻokō ʻana i ke code hale, e hōʻoia mau me ka palapala hōʻike hōʻike a ka mea hana (DIN 4102 B1 a i ʻole EN 13501-1 Class B-s1-d0).
Hiki iaʻu ke pena i ka PVC foam board i kekahi kala?
ʻAe — ʻae ʻia ka papa ʻōhua PVC i ka acrylic i hoʻopaʻa ʻia i ka wai a me ʻelua ʻāpana polyurethane pena maikaʻi. No nā papa ʻili Celuka, ʻaʻohe mea e pono ai. E pale i nā waihoʻoluʻu ʻeleʻele (ʻeleʻele hoʻi) ma nā papa i ka lā piha ma waho, no ka mea, hiki i ka hoʻonui ʻana i ka wela ke piʻi i ka 7mm no ka mika ka lōʻihi, hiki ke hoʻoulu ʻia inā paʻa paʻa ka papa ma nā kihi ʻelua.
