Pepa Puka PVC: ʻO ka Density, Durability & Signage Guide

Pepa Puhu PVC ʻO ka mānoanoa: Ke koho ʻana i ka papa kūpono no kāu noi

ʻO ka Density ka hoʻololi kikoʻī mua i Pepa pahupahu PVC koho. Hoʻoholo ʻo ia i ka rigidity, ka paʻakikī o ka ʻili, ka machinability, ka ikaika hoʻopaʻa ʻana, a me ke kaumaha o kēlā me kēia panel - a ʻo ke koho ʻana i ka māka haʻahaʻa hewa ʻo ia ke kumu maʻamau o nā hāʻule ʻana o ka hana ma ka hōʻailona a me nā noi hana.

Kūlana-nui Pepa pahupahu PVC ma 0.45–0.55 g/cm³ uhi i ka hapa nui o nā noi hōʻailona a hōʻike. No ka hoʻokele ʻana o CNC, ka nui o nā leka, a me nā noi e koi ana i ka hoʻopaʻa ʻana i ka mea hoʻopaʻa, ua kuhikuhi ʻia nā māka kiʻekiʻe ma 0.55–0.65 g/cm³. ʻOi aku ke ʻano o nā māka ultra-dense ma luna o 0.70 g/cm³ e like me ka pepa PVC paʻa a hoʻohana ʻia i ka ʻenekinia a me nā noi kai kahi e koi ʻia ai ka lakio ʻoʻoleʻa-a-kaumaha.

ʻOi aku ka lōʻihi ma mua o ka hoʻokūkū

Pepa pahupahu PVC pale i nā ʻano hemahema e hoʻohaʻahaʻa i nā mea ʻē aʻe i ka manawa: ʻaʻole ia e komo i ka makū, ʻaʻole pala, ʻaʻole ʻino, a ʻaʻole hoʻi delaminate. Ke pale kino nei ka hoʻoheheʻe ʻana i ka wai i loko o ka panel, ʻoiai ka ʻili PVC i hoʻokuʻu ʻia e hāʻawi i kahi ʻili inert kemika e kūʻē i nā aila, nā mea hoʻomaʻemaʻe, a me nā ʻakika ʻoluʻolu me ka ʻole o ka hoʻohaʻahaʻa ʻana.

I nā hoʻokolohua ʻelemakule wikiwiki i hana ʻia i ASTM D4329, UV-stabilized Pepa pahupahu PVC paʻa ma luna o 85% o ka ikaika tensile mua a me ka ʻālohilohi o ka ʻili ma hope o 2,000 mau hola o ka hoʻolaha ʻana o UV - e like me 5 mau makahiki o ka ʻike piha ʻana i waho i nā piʻi wela. Paipai ʻia nā māka i hoʻopaʻa ʻole ʻia no nā noi i loko wale nō.

Kūleʻa i ka Lewa: Hana ʻia no ka noho mau ʻana o waho

ʻO ke kū ʻana o ka wā ma Pepa pahupahu PVC he hana o ka hoʻopololei ʻana, ʻaʻole ka mānoanoa. ʻO nā UV stabilizers a me ka TiO2 puaʻa e hoʻouka ana i loko o ka pūhui extrusion e hoʻoholo i ka lōʻihi o ka mālama ʻana o ka ʻili i ka waihoʻoluʻu, ʻālohilohi, a me ka pono o ka dimensional ma lalo o ka hoʻomau mau ʻana o ka lā, ka paikikala wela, a me ka ʻike ʻana i ka wai.

ʻO nā waiwai kūʻē i ka wā e hoʻokaʻawale i ke kūlana kikoʻī mai ka waiwai Pepa pahupahu PVC Hoʻokomo pū ʻia ka manaʻo hoʻopaʻa UV (ka liʻiliʻi he 0.3% ma ke kaumaha), ka hoʻouka ʻana o TiO2 no ka opacity a me ka noʻonoʻo ʻana o UV (maʻamau 8-12%), a me ka mānoanoa o ka ʻili - ʻoi aku ka mānoanoa o ka ʻili e kūʻē i ka ʻili ʻili a me ka micro-cracking e hoʻomaka i ka pōʻaiapili degradation ma nā papa haʻahaʻa.

ʻO ka pepa PVC Foam no ka hōʻailona: No ke aha ʻo ia ke kūlana ʻoihana

ʻO ka hōʻailona hōʻailona o ka honua Pepa pahupahu PVC no ka mea, ʻaʻole ia he kuʻikahi - ʻo ia ka hopena o nā makahiki he nui o ka hoʻohālikelike ʻana me ka alumini composite, corrugated plastic, MDF, a me PVC paʻa. ʻAʻohe mea ʻē aʻe e hāʻawi i ka hui like ʻana o ka loaʻa ʻana o ka paʻi, machinability, dimensional stability, a me ke kumu kūʻai no ka mika square.

• Paʻi ʻana o UV Flatbed: ʻO ka ʻili paʻa paʻa paʻa e ʻae i nā inika UV-curable me ka ʻole o ka hoʻomaka ʻana i nā māka maʻamau a me nā māka kiʻekiʻe, e hana ana i nā kiko kiko kiko a me nā waiwai adhesion kiʻekiʻe ma luna o 3B ma nā hoʻāʻo ʻana i ka lipine cross-cut.
• Paʻi ʻana a me ka latex: ʻO ka ikehu ʻili o 38–42 mN/m ma nā māka maʻamau e hōʻoia i ka hoʻopili ʻana i ka ʻīnika maikaʻi loa no ka solvent format ākea, eco-solvent, a me nā ʻōnaehana paʻi latex me ka ʻole o ka corona a i ʻole ke ahi.
• Palapala Vinyl: ʻO ka porosity haʻahaʻa haʻahaʻa a me ka palahalaha mau e pale i ke kahe koko a paʻa i nā ʻōpū o ka ea, e hana ana i ka pahu PVC ka substrate i makemake ʻia no nā overlaminates vinyl paʻakikī a ʻokiʻoki i nā leka vinyl.
• Ka nui palapala a me ka hoʻokele CNC: Hoʻopau maʻemaʻe nā māka kiʻekiʻe ma ka wikiwiki o nā mea hana carbide maʻamau o 18,000-24,000 RPM me ka liʻiliʻi o ka burring, hiki ke hana i nā leka kahawai, nā ʻoki logo, a me nā panela me ka ʻole o ka pau ʻana o ke kaʻina hana.

ʻO ka PVC Foam Sheet Machining: Nā mea hiki a me nā mea kiko'ī

Pepa pahupahu PVC nā mīkini me nā mea hana lāʻau maʻamau a me nā mea hana plastik - ʻaʻohe pono o nā mea hana kūikawā. ʻO nā mea ʻoki ʻoki, nā ala, nā drills, nā ʻili, a me nā thermoforms i wānana ʻia ma waena o kona laulā piha piha, me nā māka kiʻekiʻe kiʻekiʻe e hana ana i nā kihi ʻoi aku ka maʻemaʻe a me nā kikoʻī maikaʻi i nā uku hānai like.

PVC Foam Sheet vs Pepa Acrylic: Hoʻohālikelike kikoʻī pololei

ʻO ke koho ma waena Pepa pahupahu PVC a ʻo ka pepa acrylic kahi hoʻoholo kikoʻī hana. ʻO nā mea ʻelua nā mea panel thermoplastic i hoʻohana nui ʻia i ka hōʻailona a me ka hōʻike ʻana, akā ʻo kā lākou mau waiwai kino, nā koi hoʻoponopono, a me nā kikoʻī kumukūʻai e kūpono i nā noi like ʻole.

FAQ: Pepa Puka PVC

He aha nā koho mānoanoa maʻamau no ka pepa pahu PVC?

ʻO nā mānoanoa hana maʻamau no ka pepa pahu PVC mai ka 1 mm a i ka 25 mm, me ka nui o ka nui o ka waihona he 3 mm, 5 mm, 6 mm, 8 mm, 10 mm, 13 mm, 15 mm, a me 19 mm. ʻO ka nui o ka pepa he 1220 x 2440 mm (4 x 8 ft) a me 1560 x 3050 mm, me nā nui maʻamau i loaʻa mai ka hapa nui o nā mea hana. ʻO ka hoʻomanawanui ʻana o ka mānoanoa no nā māka maʻamau he 0.2 mm a i ʻole ka liʻiliʻi ma waena o ka papa piha.

Hiki ke pena a uhi ʻia paha ka pepa pahu PVC ma hope o ka hana ʻana?

ʻAe. ʻO ka pepa ʻōhua PVC e ʻae i ka pena acrylic i hoʻopaʻa ʻia i ka wai, nā ʻāpana polyurethane ʻelua ʻāpana, a me ka pīpī ʻana i nā enamels pololei ma nā ʻili one me ka ʻole o ka hoʻomaka ʻana i ka hapa nui o nā māka. No ka hoʻopau maikaʻi ʻana a i ʻole nā ​​​​ʻano kaʻa, kahi one māmā a hiki i 220 grit a ukali ʻia e kahi mea hoʻolaha adhesion e pili ana i ka PVC e hōʻoia i ka hoʻopili ʻana o ka uhi a me ka paʻa ʻana o ka nani. Pono e ʻalo ʻia nā mea hoʻoheheʻe koʻikoʻi e like me ka lacquer thinners a i ʻole nā ​​pena ketone-based no ka mea hiki ke hoʻoulu i ka ʻili o ka ʻili.

Ua helu ʻia ke ahi pepa pahu PVC no nā noi kūkulu hale?

Loaʻa nā māka pepa pahu pahu PVC i hoʻopaʻa ʻia i ke ahi e kū ana i nā koi EN 13501-1 Class B-s1, d0 a me ASTM E84 Class A a i ʻole Class B, ma muli o ka hoʻokumu ʻana a me ka mānoanoa. ʻO nā māka pāʻoihana maʻamau me ka ʻole o nā mea hoʻohui ahi he maʻamau ka papa C a i ʻole ka papa D ma lalo o EN 13501-1. No ke kūkulu ʻana i ka ʻili o loko, nā tile kaupaku, a i ʻole kekahi noi i hoʻokele ʻia e nā code kūkulu hale, pono nā mea kikoʻī e hōʻoia i ka hoʻokaʻawale ʻana o ke ahi o ka pae kikoʻī a me ka mānoanoa i hoʻohana ʻia.

Pehea e mālama ʻia ai ka pepa pahu PVC e pale ai i ka warping?

Pono e mālama ʻia ka pepa pahu PVC ma luna o ka ʻili pae a i ʻole ma ke kihi me ke kākoʻo lōʻihi ma ka liʻiliʻi o ʻekolu mau wahi hoʻopili like ʻole. ʻO ka hoʻopaʻa ʻana ma luna o nā kākoʻo like ʻole a i ʻole ka waiho ʻana o ka cantilever e hāʻule mau i nā ʻāpana ʻoi aku ka lahilahi ma mua o 6 mm. Pono e mālama ʻia ka mahana o ka mālama ʻana ma lalo o 40°C, no ka mea, ʻo ka wela mau ma luna o kēia paepae e hoʻoneʻe mālie ai ka wela i nā māka maʻamau. Pono e hoʻomaʻamaʻa ʻia nā lau i ka mahana o ka kaiapuni i hoʻokomo ʻia no 24 mau hola ma mua o ka hana ʻana e hōʻemi i ka hoʻololi ʻana ma hope o ka hoʻokomo ʻana.
