He aha ka PVCʻia?

PVC kumuhana i kemikala polymers i nā kumu polymers. Ma ke kūlana o ka maka mea ua hoʻohana 'ia i loko o ka nui o ka chlorine 57%, a me kaʻaila i loko o ka nui o 43%.

mau hōʻikeʻano

PVC pili i kemikala thermoplastic mea. Ke kaumaha ma muli mea polymerization olelo a pau, hua mai la i kekahi huahana a hiki i kekahi Nine Inch a me physical ano. PVC-ka nānā 'ana i nā mea hiki ke plasticized a me ka' ole-plasticized. Ma helehelena, Tewetewe koloriside mea he keʻokeʻo he lepo lā i mea odorless a me kaʻaiʻana. Ua mau nō, he maikaʻi dielectric ano e like me insoluble i loko o ka wai. PVC kumuhana e hoʻopale i ka waiʻona mai ke kino, alkalis, mea pōhaku mea kāhinu,. Ka mea, ua wailana i loko o Etera, mua i pehu. E like me nā'uheheʻe ke hana ketones, onaona, a chlorinated hydrocarbons. Ka mea i ho'ākāka 'ia nā mea hoʻopale i ka'okesaside a aneane flammable. He hoʻopale, haʻahaʻa thermal kumupaʻa, a me ka wā ma lalo ia o ka wela o ka 100 degere decomposes ho hoʻokuʻu akula hydrogen koloriside. I mea e loaʻa ai? Ienoai aa solubility a kiʻekiʻe wela ia'ku, Tewetewe koloriside ua chlorinated.

I ka papa kuhikuhiE physico-Nine Inch ano

Hakakino kaumaha papa koa mai ka 40 000 a hiki i 145 000. ka mea autoignited i ka wela a mea like i ka 1100 degere. Oiai ka waihonaʻike wahi o 500 degere. Keʻanapu ia lŘlŘ i 624 degere. Nuʻa mea ma ka laulā o ka 1.34 gram no cubic kenimika. Ke bulk nuʻa loli aʻe mai 0,4 e 0,7 nā huna no cubic kenimika. PVC kumuhana hoʻomaka e decompose i 100-140 degere. Vitrification ua lawe mai ma 70-80 degere.

? aneie hoakaka

Tewetewe koloriside mea he ikiʻawahia waiwai a me ka decomposition nā huahana ke i ae hookaawale ana i na kanaka maluna naehana'āpana. Loaa ka lepo o ke ahi. Inā ka mea ua enaena oi ma mua o 150 degere, ka hoʻololi iho o ka pīlali hoʻomaka, pu ma evolution o ka hydrogen koloriside a me ka kalapona monoxide. Mau keʻano o ka hanaʻana i nā palapala i ke kanaka kino.

PVC mea hiki ke noke hoʻohana i kekahi i kā mākou ana wela like i 60 degere. Plasticized? Ueo hiki o undergoing anuanu maila i -60 degere.

Inā 'oe e hoihoi i loko o ka ninau o ka mea PVC mea, e mea pono no ka ike lea i? Iecaianoaaiiuo enehana ka. Common ka paʻakai ua decomposed i electrolysis ma ka hydrogen, chlorine a me caustic soda. Mālama 'mua ke keʻena ua mea hoʻoheheʻe i loko o ka wai, a me ka decomposition i wahi ma lalo o ka aoao o ka pila uku ole. Kaawale mai ke kinoea a me ka aila ma kekahi kaʻina i kapaia o ńlua, lawe'etolina? Iecaianoaaiiie. I kekahiʻanuʻu ka chlorine hui a me ka acetylene. E ho'ōla i ka'etolina dichloride ua loaa i, ma hope o hoʻohana no ka? Iecaianoaaiiie o vinyl koloriside lātoma. He ka hope ke keʻena hana me ke kumu hoa i loko o ka hana o PVC. Iloko o ka polymerization o vinyl koloriside lātoma nā lātoma i hui, o ka hopena mea hiki e loaaʻi granules. He kekahi mea i ka maka mea, a ua hui pu ia mea me ka dukima o ka waiwai, i mea e loaʻa ai i ka laulāʻano o nā 'ano o ka mea.

Products i ka PVC

I o PVC mea a pau ano o nā huahana i keia mea he mea. E hana i kēia, hoʻohana okoa loea, i waena o lākou nō ka ua hiolo, mōlina ma lalo o ka puʻuwai a me ka extrusion. Wehe PVC, no ka laʻana, hoʻohana no ka? Iecaianoaaiiie o palupalu, paʻakikī a me ka kalaka nui-pahee a me ka plasticized lula ea. Emulsion PVC mea i ke kumu no ka pahee huahana.

Laulā o ka i

Material PVC-lole komoʻuʻuku nona, maopopo i ke kanaka ma muli o PVC, ua loaʻa i keia la kona palapala noi i laau lapaau. Ke impetus no ka nuipa a hana i loko o kēia wahi,ʻo ia ka pono, e puku i ke aniani a me ka laholio, a sterilized disposable a me ka reusable. Over manawa, PVC ua loaʻa hou he ākea ma muli o ka 'oni' ana a me ka Nine Inch kumupaʻa. Lapaʻau o huahana i o PVC, hiki ke hoʻohana i loko o ke kino o ke kanaka, ka mea e ole crack maʻalahi sterilized a aole i liu.

Tewetewe koloriside ua hoʻomano māhele like me ka mea i kaa? Iecaianoaaiiuo. Ma ka nō ka mea, o ka lua o ka loa nui pīlali ma hope o polypropylene. Ma ke kaʻa hana ka mea, ua hoʻohana 'ia no ka hana o ka hoailona iho la i' atikala, ka paleʻana, uwea'īpale, limaʻanuʻu, mea hana puka makani,ʻoki, a pela aku. I ka pa apŘ o ka mea o PVC a me kona 'ē aʻe ano helu' ia ma luna, e hohola aku i ka manawa o ke ola o ke kaʻa. I keia la, i ka palapala hoʻokō manawa o 17 makahiki, oiai nō i loko o nā seventies o ka hope ke kenekulia, keia huahelu ua i oi aku mamua o 11 makahiki.

Noi i loko o ke kula i alakai i haʻahaʻa wahie na koina. O ke kumu ho i ka mea i ka pīlali kaupaona emi mai, me ka kaʻa e like ai ua i hoemiia. Tewetewe koloriside ua hoʻokāʻoi 'ke kaa i ka maluhia. Ua Ua hoʻohana 'ia i loko o ka? Iecaianoaaiiie o na Panel, airbags a me nā mea a pau. Material ia'ku e ke ahi, hoi, maoli i ka maluhia o ke kaʻa.

Inā 'oe manaʻo e pili ana i ka mea PVC mea, ia mea pono e ike no hoi i ka mea, ua' Imi hoʻohana no ka manao hana. O ke kumu ho i ka mea e mai ia makou ke hana i nā huahana o kekahi shape.

E hoʻohana i kukulu

Inā mākou e noonoo a pau o na polymers, ka mea, o ka loa hoʻomano hoʻohana PVC i kūkulu. I ka papa kuhikuhiE ano i i mahalo i ke akamai, hiki e kūlana Wear ia'ku, haʻahaʻa ke kaupaonaʻana, ma paʻi ikaika, ia'ku i ka popopo, a me keʻano o ka hanaʻana, e like me thermal 'ole a me ka nanaʻike manaʻo. PVC hiki ke kapaia he maikaʻi refractory mea, i mea pilikia e ignite. I mea no ke aha la ka mea hiki ke hoʻohana 'ia ma luna o ia mau kahua, a mea paha i kūikawā e pono ai no ke ahi maluhia.

ka hopena

Inā e koho e hana PVC no ka hana, i nā mea maikaʻi ma mua o ia, ia mea nui e hooholo mua ke kuai. Naʻe, ka mea e e kaulana i PVC ua hoʻomano palahalaha ae ma kekahi wahi no kaʻano o Pahuhopu kumu. Ka hapa nui o ia i ua hōʻike ma ka pauku.
